Sir:<br />

Transmitted, herewith, is Part I1 <strong>of</strong> <strong>Bulletin</strong> 61, <strong>The</strong> <strong>Cretaceous</strong><br />

Fossils <strong>of</strong> h'eur <strong>Jersey</strong>. This, together with the already published Part<br />

I, will provide up-to-date references and descriptions <strong>of</strong> the <strong>fossils</strong> <strong>of</strong><br />

the <strong>Cretaceous</strong> formations <strong>of</strong> the <strong>New</strong> <strong>Jersey</strong> Coastal Plain. Basic information<br />

such as this is needed for the development <strong>of</strong> nat.ural resources<br />

(particularly water, oil and natural gas) where the occurrence<br />

<strong>of</strong> these resources is restricted to specific geologic formations. Tlie<br />

identification <strong>of</strong> <strong>fossils</strong> removed from core borings and drill holes permits<br />

the identification <strong>of</strong> specific formations at great depth 1)elow the<br />

surface. Although oil and natural gas hare not been found in <strong>New</strong><br />

<strong>Jersey</strong>, there is increasing interest in the geologic conditions in the<br />

Coastal Plain.<br />

A11 authors were requested to follolv a specified, concise style in<br />

writing their descriptions <strong>of</strong> <strong>fossils</strong>. No attempt ~vas made to change<br />

the minor variations in the general format because each author was considered<br />

the espert best acquainted with the ~lescriptive style generally<br />

used by his colleagues in the same field.<br />

Respectfully submitted,<br />

two full volntions shown in the internal cast, with the suture well defined<br />

Description.-"\Vhorls very convex, with four equidistant, revolving,<br />

raised lines, 1~11ieh are crossed by equidistant longitudinal ribs<br />

<strong>of</strong> a corresponding size, which form equal, q~ta(Irate, interstices, except,<br />

below the suture \\-here t,he longitudinal rills become obsolete. At tlrc<br />

junction <strong>of</strong> the two series <strong>of</strong> raised lines are small tubercles throughout<br />

the entire shell. Owing to the imperfect apertures <strong>of</strong> the five specimens,<br />

its generic position remains doubtful, but its distinct sculpture will<br />

distinguish the species. Length <strong>of</strong> the larg,:st speeimens. 6 mill. prol~ably<br />

attains the length <strong>of</strong> about 10 mill." (Johnson)<br />

volutions five or more, very round and full, hut closely compacted; thc<br />

suture line deep and sharp, but close; aperture (as shown on the only<br />

specimen in hand, which is a matrix containing thc shell <strong>of</strong> one side <strong>of</strong><br />

the specimen in place and from which a gutta-percha cast is taken for<br />

description and figure), is round, but the margin is not preserved;<br />

surface <strong>of</strong> the shell marked by oblique varices, which have a slightly<br />

backward direction in crossing from the upper to the lower side <strong>of</strong><br />

the volution; the Tarices are thin and recurved, ,and numher eight<br />

on one-half <strong>of</strong> the circumference <strong>of</strong> the last volution, but decrease<br />

somewhat in number toward the apex <strong>of</strong> the spire; axis imperforate:<br />

the base <strong>of</strong> the last volution bordered by a raised carina, helolr<br />

which the varices do not appear to extend. So far as can he ascertained<br />

from the specimen, I should judge that the varices were slightly<br />

produced in the upper part to form subspines around the base <strong>of</strong> tl~e<br />

preceding volntion. <strong>The</strong> minute surface character <strong>of</strong> the shcll ean not<br />

be ascertained from the specimen in use, as only the inside <strong>of</strong> the substance<br />

Description.-"Shell <strong>of</strong> large size, robust in proportions, number. -<br />

<strong>of</strong> volutions unknown but compact, comparatively-shcri,.not very ventricose<br />

and closely united at the suture line_s;.ilfiical angle 20' to 2s0,<br />

giving a rather elongated spire ; volutions crossed b$f'from 12 to 14 very<br />

strong vertical varices, which form thick rounded ribs, rather closely<br />

arranged, and each marked by two rounded tubercles, one just below<br />

the upper suture line and the other near the lower su,ture !ine-; also a<br />

central line <strong>of</strong> smaller ridge-like nodes intermediat$;Wetw&n the other<br />

two, apparent on the last volution, marking the'position <strong>of</strong> a spiral<br />

carina on the center <strong>of</strong> the volution, while other spiral earinae cross the<br />

upper and lower lines <strong>of</strong> nodes, and on the base <strong>of</strong> the last volat,ion the<br />

usual carina surrounding the umbilicus is also marked by a thickening<br />

<strong>of</strong> the vertical ribs, but ~vithout forming distinct ribs; form <strong>of</strong> aperture<br />

and intermediate surface structure nn(leterminec1," (%'hitfield)<br />

Remarks.-"<strong>The</strong> original specimens used hy Whitfield are very in-<br />

complete. <strong>The</strong> species is a large one and the larger specimen used hy<br />

Whitfield must have been 100 mm. or more in height and 30 mm. or<br />

more in maximum diameter. <strong>The</strong> vertical ribs upon the volutions <strong>of</strong><br />

this species arc somelvhat different than is usual in the genus, they he-<br />

ing rounded, thickened ribs and not simply varieal lips, the rariz hav-<br />

ing been filled to a solid rib before the growth <strong>of</strong> the shell had pro-<br />

gressed beyond it. <strong>The</strong> number <strong>of</strong> rarices varies somewhat in the dif-<br />

ferent volutions. <strong>The</strong> finer markings <strong>of</strong> the shell are not ell prl:servecl<br />

in the specimens, but on one specimen they seen1 to consist <strong>of</strong> ~:loselg-<br />

only fragments representing medium sized parts <strong>of</strong> the tubes, or parts<br />

from the large irregularly coiled portions. <strong>The</strong> tube is very gradually<br />

tapering, and either compactly or loosely coiled in the upper part, but<br />

all show their relations to the genus Siliquaria, by the narrow ridge<br />

left along the upper side <strong>of</strong> the tube by the material whicli has filled the<br />

slit. <strong>The</strong>re is no distinctive feature represented on the specimens by<br />

which they can be distinguisllcd from casts <strong>of</strong> other species <strong>of</strong> the genus ;<br />

a narrow, almost closed sutural cavity, indicating a thin shell, and they<br />

Description.--Shell with a rather high spire having an apical angle<br />

<strong>of</strong> about 30°, and a comparatively short body volution, with a slender<br />

rostrate, anterior canal; the dimensions <strong>of</strong> a moderately large internal<br />

east retaining a little more than three volutions, and incomplete at both<br />

the apex and the anterior extremity, are: length, 51mm.; greatest diameter,<br />

30 mm.; height <strong>of</strong> aperture, 21.5 mm.; width <strong>of</strong> aperture, 10.5<br />

mm. If this specimen were complete it would have an additional height<br />

at the apex <strong>of</strong> about 20 mm., and an anterior beak about 30 mm. in<br />

length. <strong>The</strong> outer lip <strong>of</strong> the aperture is produced and terminates in t\vo<br />

unequal pointed proeesses--one directed forward and the otlier baek-<br />

ward. Surface <strong>of</strong> the shell marked by a rather strong, nodose, subangu-<br />

lar, revolving keel at a little above the mid-height <strong>of</strong> the outer volution.<br />

Upon the expanded portion <strong>of</strong> the outer lip this keel curves upward to<br />

the posterior process <strong>of</strong> the lip. Above and below the median keel the<br />

surface is marked hy moderately broad, rather depressed revolving ribs,<br />

and by less conspicuous vertical markings. On the internal casts, in<br />

which condition only the species has been seen in <strong>New</strong> <strong>Jersey</strong>, the sur-<br />

face is marked in the younger individuals by more or less indistinct re-<br />

volving and vertical ribs, which evidently were obliterated by the in-<br />

ternal thickening <strong>of</strong> the shell, since the larger individuals are all smooth.<br />

<strong>The</strong> aperture in the casts is narrowly subelliptical in outline, the outer<br />

side being a little more strongly curved than the inner. l'hc eolumellar<br />

cavity left in the casts is rather broad and is not marked by revolving<br />

folds. (Weller)<br />

Remarks.-<strong>New</strong> <strong>Jersey</strong> specimens have been observed only as in-<br />

ternal casts in which the apex and the outer lip <strong>of</strong> the aperture have<br />

been imperfectly preserved.<br />

appear to have been somewhat sigmoidally curved in passing from<br />

above downward, being directed slightly forward below. (Weller)<br />

Top portion <strong>of</strong> type not preserved. I'rominent lateral ribs on each<br />

the incomplete preservation <strong>of</strong> the type, it is impossible to estimate the<br />

number <strong>of</strong> ribs. However, they are slightly closer together and ap-<br />

parently more numerous than in A. pontana Stephenson. Tbe body<br />

whorl is covered with conspicuous spiral ribs separated by interspaces<br />

<strong>of</strong> irregular width. No riblets were observed in the interspaces. <strong>The</strong><br />

crossing <strong>of</strong> the spirals and growth ridges produces a semi-eaneellated<br />

penultimate and antepenultimate. Because <strong>of</strong> the lack <strong>of</strong> a perfect<br />

penultimate whorl they are approximately 2 mm. apart. A fair trace<br />

<strong>of</strong> spiral lines can be seen on the body whorl. <strong>The</strong> outer lip was ap-<br />

parently greatly expander1 to form a wing-like structure, character-<br />

Description.-<strong>The</strong> dimensions <strong>of</strong> tlie type specimen, with some res-<br />

toration, are: height, 25mm. ; height <strong>of</strong> spire, 14mm. ; greatest diameter,<br />

15 mm.; apical angle, about 40'. Shell with probably five or six volu-<br />

tions, the suture well defined, the outer volution produced below into<br />

a very short anterior canal. Surface <strong>of</strong> the volutions <strong>of</strong> the spire con-<br />

vex from suture to suture, the curvature a little flattened above, with<br />

about 12 strong subangular vertical nodes or varices upon each volu-<br />

tion, which extend from suture to suture and are separated by broad<br />

eoncave areas. Upon the outer volution t.he varices become obsolete be-<br />

low, and the surface becomes concave as it passes into the short anterior<br />

canal. Aperture suhovate in outline, somewhat oblique, pointed below,<br />

about twice as high as wide ; at the lower extremity <strong>of</strong> the columellar<br />

lip in the cast three notches can be detected which seem to indicate the<br />

presence <strong>of</strong> three somewhat obscure revolving columellar folds; the<br />

outer lip is marked by revolving ribs internally. <strong>The</strong> surface <strong>of</strong> tlie<br />

shell is marked by revolving costae about one millimeter apart, with<br />

the spaces between filled with exceedingly fine revolving lines; the cli-<br />

tire surface is also marked with exceedingly fine transverse lines <strong>of</strong><br />

growth. (Weller)<br />

Ren~arks.-<strong>The</strong> type <strong>of</strong> this species consists <strong>of</strong> an incomplete in-<br />

ternal cast which has been restored to its normal form so far as pos-<br />

sible, and a partial impression <strong>of</strong> the exterior, which has furnished thc<br />

character <strong>of</strong> the finer surface markings. Upon the casts the vertical<br />

nodes are well shown, but are broader and rounder than on the shell<br />

itself, and the stronger revolving costae are present to\vards the aper-<br />

Description.-<strong>The</strong> dimensions <strong>of</strong> the type specimen are: height, 29<br />

mm. ; height <strong>of</strong> spire, 7 mm. ; greatest diameter, 17.5 mm. ; apical angle<br />

about 75". Shell pyriform with four or fire oolutions, the outer volution<br />

the nodes are produced below for a short distance as obscure, rounded<br />

ridges; between the sutural ridge or shouldcr and the row <strong>of</strong> nodes,<br />

the surface is concave; below the row <strong>of</strong> nodes the surface is broadly<br />

and regularly convex, becoming concave below as it passes into the an-<br />

terior canal. Surface ornamented by obscure lines <strong>of</strong> growth which<br />

show a broad but slight sinuosity beneath the suture. Columella with<br />

two faint revolving folds. (Weller)<br />

Remarks.-"<strong>The</strong> best specimen <strong>of</strong> this species which has been ob-<br />

served consists <strong>of</strong> a nearly complete internal cast with a partial mould<br />

<strong>of</strong> the exterior from which a plaster cast has been taken. Only the<br />

larger nodes, those near the aperture, are visible upon the cast. <strong>The</strong><br />

species is especially characterized by its curved anterior canals. <strong>The</strong><br />

folds <strong>of</strong> the columella are seen only as impressions in the cast;, and are<br />

almost too faint to be detected except when the specimen is held in a<br />

certain position.<br />

This species resembles Strepsidzcra tippana Conrad, a species which<br />

mas afterwards placed by the same author in his genus Hercorhynchus.<br />

<strong>The</strong> <strong>New</strong> Jersev shell differs from this form, however. in the absence <strong>of</strong><br />

the convexity and in the sharpness <strong>of</strong> the contraction <strong>of</strong> the body is<br />

were preserved, but in the absence <strong>of</strong> these there are not very<br />

satisfactory criteria for separation." (Gardner)<br />

Ren1arks.-This species is evidently not a true Pyropsis because <strong>of</strong><br />

the presence <strong>of</strong> the eolumcllar fold. Whitfield was not able "to place it<br />

satisfactorily under any known genus," at the time he described it,<br />

and it may he allowed to remain with a question, where it mas placed<br />

groove, indicating the presence <strong>of</strong> a rather strong, tooth-like ridge<br />

at the base <strong>of</strong> the colt~mclla; columella concave, giving an elliptical form<br />

to the filling <strong>of</strong> the aperture which nearly equals one-half the height,<br />

<strong>of</strong> the entire cast, and is very oblique as seen in front, but from the<br />

Description.-"Shell small, pyriform; volutions ahout three, very<br />

contracted to form a moderately long, slender canal and bealr, which<br />

is very slightly bent; splre low, hut the inner volutions distinctly show-<br />

ing above the outer ones, with a well-defined suture; aperture elongate-<br />

elliptical, prolonged below to the end <strong>of</strong> the canal, which is very nar-<br />

row; surface <strong>of</strong> the shell marked by 12 principal prominent, spiral<br />

carina, between vhich there is in each space a single subordinate ridge<br />

showing on the east; toward the lower part <strong>of</strong> the volution and on the<br />

beak they are more equal in size, and on the body <strong>of</strong> the volution the<br />

principal carina are nodose, or serrated, from the crossing <strong>of</strong> transverse<br />

ribs which pass across the volution in a nearly straight line parallel to<br />

the margin <strong>of</strong> the outer lip <strong>of</strong> the aperture. In a fragment <strong>of</strong> the matrix,<br />

from near the inner part <strong>of</strong> the outer whorl the principal spiral ridges<br />

are seen to be sharply carinate, and the transverse striae fine and nu-<br />

merous; eolun~ella without ridges or folds <strong>of</strong> any kind." (Whitfield)<br />

Remarks.-This species somewhat resembles h7apulus retifor<br />

(Gahb). In this respect IVeller states: "<strong>The</strong> casts <strong>of</strong> P. precedens,<br />

however, do not show so large a columellar cavity and the anterior beak<br />

is more slender. <strong>The</strong> spiral ridges are also more numerous and more<br />

sharply elevated than in P. (i.e., A'apnlus) retijer, and the decided al-<br />

ternation among them is a distinguishing character."<br />

alternately larger and smaller, and very closely arranged; these again<br />

crossed by fine transverse lines <strong>of</strong> growth, which make a broad and<br />

near the middle <strong>of</strong> its length; attenuate and rostrate below, and nearly<br />

or quite one-half the length <strong>of</strong> the shell as seen from the outside <strong>of</strong> the<br />

aperture; sutures very distinct, bordered by a broad band which is very<br />

distinctly separated from the other part <strong>of</strong> the volution by an impressed<br />

line nearly or quite as deep and distinctly marked as the suture line itself;<br />

surface <strong>of</strong> the shell marked by numerous vertical folds, with slightly<br />

concave spaces between; the folds are narrow and distinct, and very<br />

slightly bent backward in the middle <strong>of</strong> their length in their passage<br />

across the volution, hut not interrupted perceptibly at the line separat-<br />

ing the band from the body <strong>of</strong> the volution, and become obsolete on the<br />

rostrated part <strong>of</strong> the last one. Besides the vertical folds, the entire<br />

shell is marked by sharp, closely arranged spiral lines, which are finer<br />

and more numerous on the upper part, becoming more distant and<br />

stronger below, especially on the lower part <strong>of</strong> the last volution, where<br />

they seem to have alternated with finer intermediate striae. This latter<br />

feature may be only apparent, however, as the condition <strong>of</strong> the speei-<br />

mens is not such as entirely to establish this feature as a character <strong>of</strong><br />

the shell. <strong>The</strong> crossing <strong>of</strong> the vertical folds by the spiral striae in the up-<br />

per volutions produces a very decided and beautifully caneellated struc-<br />

ture.'' (Whitfield)<br />

Descriptioa.-"Shell fusiform, with a moderately elevated and<br />

turreted spire, the apical anglc <strong>of</strong> which is somewhat less than 30';<br />

volutions five or six in number, flattened in the direction <strong>of</strong> the spire,<br />

or very little eonvex on the surface, and bordcred on the lower margins<br />

in the cast by a distinct band, which forms about one-third <strong>of</strong> the<br />

height; body ~olution proportionally rather more convex in the middle<br />

than the others and constricted below, forming a beak <strong>of</strong> moderate<br />

length; the height <strong>of</strong> this volution as seen from the back <strong>of</strong> the outer<br />

lip forms, with the beak, rather more than one-half <strong>of</strong> the entire length<br />

<strong>of</strong> tlic shell ;shell m;~rked t,liro~~gl~out by clistinct verticlil ridges or folds,<br />

more numerous and more closely arranged on the body whorl than on<br />

those above? esccpt perhaps the apical ones, and have a slight backward<br />

curvature in t,l~c middle in passing from suture to suture; the shell also<br />

marked by spiral ridges which, on thc body volution, are <strong>of</strong> nearly<br />

equal strength with the vertical folds, but are invisible on the other rolutions<br />

in the specimens used." (Whitfield)<br />

Remarks.-This species differs from Vz~bpccula reileyi in its less<br />

slender form and its proportionally shorter spire with a smaller num-<br />

ber <strong>of</strong> volutions; and in the coarser surface markings. (Weller)<br />

CRETACEOUS NAUTILOIDS OF XEX' JERSEY<br />

In North America Late Mesozoic nautiloids are <strong>of</strong> \\ridespread oc-<br />

currence, are not particularly rare, and are locally rather abundant,.<br />

However, their variety is limited, and only five genera arc knomn to<br />

be represented in our <strong>Cretaceous</strong> strata: Cymatocerm, Paracj~n~ato-<br />

ceras, Eleminautilus, Auplithes, and Eutrephoceras. <strong>The</strong> first tmo <strong>of</strong><br />

these belong in the family Cymatoceratidae, which in 1945 was treated<br />

in detail by Miller and IIarris', who discussed all <strong>of</strong> the American<br />

species known at that time; most <strong>of</strong> them are Lower <strong>Cretaceous</strong> in age,<br />

as are the single knomn representatives <strong>of</strong> Hominat~tilus and Angu-<br />

lathes. Eutrephoceras is therefore the only genus that has been found<br />

to occur in any abundance in the North American Upper <strong>Cretaceous</strong>.<br />

It is known to he <strong>of</strong> widespread distribution in those strata, and alto-<br />

gether we have been able to assemble almost a hundred specimens from<br />

six states. In addition, the literature contains data in regard to forms<br />

from these and ten other states and from one <strong>of</strong> the provinces <strong>of</strong> Canada.<br />

1 Family Eutrephoceratidae Miller<br />

In 1951 Miller ~ointed out that the genus Eut~ephocerm is not<br />

particularly close to Naz~tilus, with which it had previously been classed<br />

in the family Nautilidae. He therefore established the monogeneric<br />

family Eutrephoceratidae. Typical representatires <strong>of</strong> it have globnlar<br />

or subglobular nautiliconic conchs, small umbilici, relatively smootl~<br />

testsa, more or less straight and directly transverse external sutures,<br />

and small central or subcentral orthochoanitic siphuncles. <strong>The</strong> internal<br />

sutures form a broad shallow rounded dorsal lobe which is due to the<br />

involution <strong>of</strong> the conch and not to an inflection <strong>of</strong> the septa. Annular<br />

lobes are present in some forms and absent in others-they are most<br />

probably <strong>of</strong> little taxonomic significance.<br />

Geographically this family seems to be <strong>of</strong> world-wide distribution.<br />

Stratigraphically it ranges from the <strong>Cretaceous</strong> to the Oligocene, inclusive,<br />

and it may be represented also in the Jurassic and the Miocene.<br />

In North America it is most abundant in the Upper <strong>Cretaceous</strong> and the<br />

Eocene.<br />

Genus Eutrephoceras Hyatt<br />

<strong>The</strong> original description <strong>of</strong> this genus, which was published in 1804,<br />

contains the statement "type Ez~trepllocerns Deliayi." Its author,<br />

When illorton established this species, he gave only a few notes in<br />

regard to it, but he illustrated a specimen which has come to be regarded<br />

as the holotype. Fortunately, it has been preserved, and<br />

through the courtesy <strong>of</strong> Dr. Horace G. Richards it has been made available<br />

to us for study (pl. 65, figs. 5, 6).<br />

This specimen, which has been somewhat restored, appears to represent<br />

an almost complete body chamber preserved in dark-colored<br />

"<br />

greensand marl.'' Its maximum overall measurement is about 8 em.,<br />

and at its adoral end its conch attains a maximum height and corresponding<br />

width <strong>of</strong> about 48 mm. and 80 mm., respectively. <strong>The</strong><br />

adapical end <strong>of</strong> this holotype is hounded by a septum, the size and shape<br />

<strong>of</strong> which are cluci~lated by text figure 1E.<br />

<strong>The</strong> conch is suhglobular, rapidly expanded orad, and broadly<br />

rounded ventrally and laterally. It is more or less semicircular in cross<br />

section but is impressed dorsally to a little more than a third its height.<br />

<strong>The</strong> lateral margins <strong>of</strong> the aperture seem to be slightly flared.<br />

Traces <strong>of</strong> fine growth lines on remnants <strong>of</strong> the test show that the aperture<br />

bears a wide, moderately deep, broadly rounded, ventral sinus and<br />

on either side <strong>of</strong> it a similar hut narrower and less broadly rounded<br />

lateral salient which extends to the umbilicus.<br />

<strong>The</strong> umbilicus is small, closed, and inconspicuous. <strong>The</strong> umbilical<br />

shoulders are rounded and indefinite.<br />

<strong>The</strong> external suture is almost straight and directly transverse. However,<br />

it forms very slight hut nevertheless distinct ventral and lateral<br />

lobes. <strong>The</strong> siphuncle is small and subcentral but is distinctly nearer the<br />

dorsum than the venter.<br />

<strong>The</strong> immediately preceding paragraphs refer specifically lo illorton's<br />

holotype, but we have under consideration a large number <strong>of</strong> specimens<br />

from a variety <strong>of</strong> Upper <strong>Cretaceous</strong> horizons at many widely<br />

separated localities in the United <strong>State</strong>s. <strong>The</strong> individual represented<br />

by figures 1 and 2 on plate 66 is essentially complete and free from distortion.<br />

Its adoral camera is shorter than the preceding ones, indieating<br />

that it had reached full maturity; and the apcrtural margins are<br />

slightly hut distinctly flared and are parallel to the grorvth lines. which<br />

located near t,he center <strong>of</strong> a median line (cf. test figs. 1C-E and<br />

qnite appropriate. It vas proposed provisionally in 1834 for internal<br />

molds that are "abundant at Prairie Bluff, Alabama, . . . are rounder<br />

no strong feelings. In general, we have found that trinomials are too<br />

eumhersome to be practicable, and therefore we are inclined to avoid<br />

their use. <strong>The</strong> case undcr consideration may, ho~rever, be one in which<br />

they are warranted, for many specimens can not be placed mith a rcasonable<br />

degree <strong>of</strong> certainty in any <strong>of</strong> t,he varieties we envisage, though<br />

they can readily be referred to E. deka.yi, as an inclusive and somewhat<br />

variable species.<br />

Certain <strong>of</strong> the features <strong>of</strong> this species seem to merit further consideration.<br />

According to Morton, some <strong>of</strong> the <strong>New</strong> <strong>Jersey</strong> specimens<br />

hen entire could have been little short <strong>of</strong> eight inches in diameter";<br />

we have an individual from the uppermost <strong>Cretaceous</strong> <strong>of</strong> Mississippi<br />

that must have had comparable dimensions ; the masimum diameter <strong>of</strong><br />

beside's holotype <strong>of</strong> E. dekayi alcesense, which is from the Telegraph<br />

Creelr formation <strong>of</strong> Wyoming, is given as 240 mm. ; when he established<br />

the last form, Reeside stated that another one "from the Mortonbernr<br />

tezanz~nt zone in the Gnlf region is stouter and even larger;'' and in<br />

1926 \Trade reported specimens from the Ripley at Coon Creek, Tennessee,<br />

"some attaining a maximum diameter <strong>of</strong> 15 or 18 inches." TTonrever,<br />

the great majority <strong>of</strong> our specimens have a diameter <strong>of</strong> less than<br />

100 mm., even when they retain the body chamber. That chamher is<br />

about half a volution in length during adolescence ant1 maturity.<br />

As shown by fignre 6 on plate 67, the extreme adapical portion <strong>of</strong><br />

the conch is very rapidly expanded orad, it bears a few transverse corrugations,<br />

and on the apes there is a slight dorso-ventrally elongate<br />

depression which is reminiscent <strong>of</strong> the alleged cicatris <strong>of</strong> ;~t,taehment <strong>of</strong><br />

the protoconch in modern Nautilz~s, which Hyatt figured long ago. Tl~e<br />

siphuncle extends to the apes <strong>of</strong> the phragmoeone, where it terminates<br />

in a caecum-in 1899 Clarke published a diagrammat,ic longitudinal<br />

section <strong>of</strong> the adapical portion <strong>of</strong> the eonch, showing the general nature<br />

<strong>of</strong> the siphuncle there. TJntil the eoneh attained a diameter <strong>of</strong> some<br />

15 mm., the esternal surface <strong>of</strong> the test was retienlate, with the longitudinal<br />

and the transverse lirae being <strong>of</strong> about equal prominence. Gradually<br />

the transverse lirae (growth lines) dcvcloped a ventral sinus and<br />

ventrolateral saddlesthcse can first be recognized at a diameter <strong>of</strong><br />

some 7 mm. Almost immediately thereafter, the longitndinal lirao<br />

gradually deereased in prominence, and they are obsolete on fully mature<br />

portions <strong>of</strong> the eonch, ~vherens the growth lines were retained<br />

thronghout ontogenetie development. During late adolescence and/or<br />

early maturity, the ventral and ventrolateral portions <strong>of</strong> the test <strong>of</strong><br />

some individuals became temporarily pustulous, a development that<br />

may have been pathological (see p1. 65, figs. 3, 4).<br />

Well preserved internal molds retain traces <strong>of</strong> the growth lines.<br />

Also, on some such specimens there is a distinct median longitudinal<br />

ridge along the venter (<strong>of</strong> \\.\.]lie11 tt~ere is no espression on the outer<br />

snrfacc <strong>of</strong> thc test).<br />

Throughout ontogenetic development, the umbilicus was small and<br />

was closed by the test, except possibly in the first volution. Thc clorso-<br />

lateral portions <strong>of</strong> the mantle secreted a relatively thick calcareous<br />

deposit, which merged with the rest <strong>of</strong> the test, tended to fill the umbilical<br />

depressions, and thus formed a structure which some authors<br />

have termed a "columella".<br />

In this species, the sutures characteristically do not form an annular<br />

lobe. However, in the specimen represented by test figure 1B tllcre<br />

seems to he a slight one. Except possibly in the extreme aclapical portion<br />

<strong>of</strong> the conch, there are about 15 to 17 camerae per volntion. In general,<br />

the length <strong>of</strong> the camerae increased progressively during ontogenetic<br />

development, though in the adoral portion <strong>of</strong> the phragmocone<br />

<strong>of</strong> large individuals the septa are closely spaced, as is characteristic <strong>of</strong><br />

fully mature nautiloids.<br />

Remarks.-Several <strong>of</strong> the authors cited in our synonymy have compared<br />

E. dekayi with certain Eurasian species, some <strong>of</strong> which, in our<br />

opinion, are not very close. For example, <strong>of</strong> the forms originally described<br />

from Britain, Nautilus elcgans Sowerby has sinuous ribs and<br />

sutures and is a cymatoceratid ; N. expaltsua Solverby is flattened ventrally<br />

and laterally, is almost subangnlar ventrolaterally, and is most<br />

probably a paracenoceratid; and A'. intperdis Solverby has sutures and<br />

a general physiognomy mliiel~ indicate that it belongs in Conrad's<br />

genus Cin~omia.<br />

As has been noted by Foord and others, the Vancouver Island,<br />

European, and African specimens that have been referred to E. dekayi<br />

sllould probably be thought <strong>of</strong> as representing distinct species. Certain<br />

<strong>Cretaceous</strong> forms have, holirever, been described from abroad that are<br />

indeed reminiscent <strong>of</strong> the one under consideration and should be regarded<br />

as congeneric with it. <strong>The</strong>se include E. lauerdei Durham <strong>of</strong> the<br />

upper Aptian <strong>of</strong> Colombia; h'autilus dlOrbignyanus Forbes <strong>of</strong> the<br />

"<strong>Cretaceous</strong>" <strong>of</strong> Chile; N. Belleropho?b Lnndgren <strong>of</strong> the Danian <strong>of</strong><br />

Denmark; N. Bouckardianus d'orbigny <strong>of</strong> the Senonian <strong>of</strong> France<br />

awl the specimens from Britain, continental Europe, and the Indian<br />

subcontinent mhich have been referred to it; N. IVekayi Fame 1869,<br />

not Morton, 1833 <strong>of</strong> the <strong>Cretaceous</strong> <strong>of</strong> southern Poland; E. denkabense<br />

Spath <strong>of</strong> the Upper Valanginian <strong>of</strong> South Africa (Uitenhage)<br />

i~nd the congeneric forms described by Spath in 1921 from the Senonian<br />

<strong>of</strong> the same general region (Zululand) ; Nautilus bla?~fordianus Kilian<br />

and Reboul <strong>of</strong> the Upper <strong>Cretaceous</strong> <strong>of</strong> the Antarctic region, etc.<br />

Occurrence.-This species, as me interpret it, is <strong>of</strong> widespread distribution<br />

in the Upper <strong>Cretaceous</strong> <strong>of</strong> the United <strong>State</strong>s and has also<br />

been recorded from the same general horizon in southwestern Canada.<br />

It is known from at least the following states and provinces: Ne~v <strong>Jersey</strong>,<br />

Delaware, Maryland, North Carolina, Tennessee, Georgia, Alabama,<br />

Mississippi, Arkansas, Missouri, Texas, Nev Mexico, Utah, Nebraska,<br />

South Dakota, Wyoming, Idaho, Montana, and Alberta or Saskatchewan.<br />

In the <strong>Cretaceous</strong> <strong>of</strong> <strong>New</strong> <strong>Jersey</strong> this species is not abundant, but<br />

it occurs in the Navesink marl and the Red Bank sand, both <strong>of</strong> the<br />

Description.-This species is best characterized 11y its small size,<br />

broad-orate eross section, small taper <strong>of</strong> the shell, and its orntunenta-<br />

tion-widely spaced round nodes on the antisiphonal half <strong>of</strong> the flanks<br />

and numerous weak undulations on the siphonal side that hare only<br />

the faintest conneet,ion mith the nodes. Forms <strong>of</strong> large size and mith<br />

arcuate nodes, even though distant, n:irrowly ovate or suhtriangular<br />

in eross section, belong to other species. As is usual with ammonites, it<br />

grades toward other species in that in some specinlens the nodes tend<br />

to show a degree <strong>of</strong> areuation, and in ot.her specimens the cross section<br />

is subcircular or tends to show a flattening <strong>of</strong> the antisiphonal sirle.<br />

Remarks.-Morton in 1833 cited only "Alabama" as ti locality, but<br />

in 1834 he wrote that the species "was discoverer1 by Xr. Nuttall at<br />

Cahawba and more recently hy Mr. Conrad at Prairie Bluff." <strong>The</strong><br />

smaller <strong>of</strong> the two specimens fi~ired in 1834 (pl. 1, figs. 13-14) is still<br />

available and is accompanied by a label in Rforton's handwriting that<br />

states the locality as Prairie Bluff. This locality would place the horizon<br />

in the Prairie Bluff chalk, but that unit is definitely higher than<br />

the levels now assigned to 13. asper in the region and elst:mhere and has<br />

not yielded the species in more recent eollect,ions. On the ot,her hand,<br />

the locality at Caha~vba should 1)c in thc lower part <strong>of</strong> the Sclma chalk,<br />

which with the Tombigbee sand memher has yielded the species at many<br />

localities and includes horizons equivalent to those that have yielded<br />

B. asper elsewhere. <strong>The</strong> evidence seems 1.0 support the judgment that<br />

Conrad's assignment, accepted by Iforton, is erroneous.<br />

<strong>The</strong> specimen from the Navesink marl illustratecl by Whitfield and<br />

by Weller as B. asper obviously does not belong to the species. Weller<br />

rer~orts, but unfortunately does not illustrate, a specimen from the<br />

Cliffwood clay (now Rlagothy formation) 10 mm. in diameter "ehar-<br />

acterized by somewhat eonspieuous node-like inflations <strong>of</strong> t,he sides <strong>of</strong><br />

shell" that may belong to B. aspor. At the horizon statecl, such an<br />

identity seems highly probable, though the writer has not seen the speci-<br />

men, and a donht must remain. <strong>The</strong> species is n,idcly rlistrihuted in mid-<br />

dle Upper <strong>Cretaceous</strong> deposits (Coniacian, Santonian, early Cnmpt~n-<br />

ian) .<br />

both [lcstral and sinistral spc:ein~ens, and eziell is a nearly co~nplctc<br />

living chamber, from the last septum to the aperture. No directly associated<br />

coile(1 parts are reported. Each specimen forms a distinct TJ,<br />

with rnore or less parallel sidcs connected by an arc, differing in this<br />

respect fron~ the more or less continuously curved living chamber reported<br />

for lIirl.jn~occras.<br />

On these specimens the ribs arc strong and widely spaced and two<br />

rows <strong>of</strong> ventral nodes are pronlinently developed, largest on the enrved<br />

part <strong>of</strong> the specimen. <strong>The</strong> cross section is snbeireular to very 11ro;idly<br />

ovate.<br />

Description.-This species rests primarily on the type, described<br />

by Iforton from the Navcsink marl at Arneytown, Burlington County,<br />

a not too well-preserved single whorl <strong>of</strong> a sinistrally coiled spiral shell.<br />

<strong>The</strong> specimen appears to be missing, but several plaster casts <strong>of</strong> it are<br />

available. It mas described as unseptate, with a cross section distorted<br />

by pressure from an original probably subcircular form into a dcpressed<br />

oval; without a depressed zone or other evidence that thc<br />

~vhorls were in contact; with surface ornamented by ribs that on thc<br />

upper surface rise from t,hc umbilicus (perhaps 40 per whorl), incline<br />

backwards, then curve radially and pass transversely orcr the outcr<br />

surface <strong>of</strong> the shell. Some <strong>of</strong> the ribs rise into a node at the midpoint.<br />

beyond which each third or fourtl~ rib joins its neighbor to form a nodc<br />

near the bottom <strong>of</strong> the outer surface. On the lower surface each rib<br />

passes mith gentle forward curve to the nmbilicus (about 30 per<br />

whorl). Whitfield attributes a second fragment to the same species<br />

and locality. No trace <strong>of</strong> the suture appears on the cast <strong>of</strong> the type<br />

or on the second specimen.<br />

Remarks.-Both Whitfield and Weller associate mith C. conradi a<br />

number <strong>of</strong> specimens <strong>of</strong> a retroversal living chamber from the Nave-<br />

sink formation at Atlantic IIighlanrls. Three additional specinlens<br />

are available at the U. S. National Mnseu~m. No directly associated sep-<br />

Descriptio+~.-This species has broad, stout whorls, a swollen living<br />

chamber with flanks smooth except for two prominent primary nodes,<br />

and nine to seven low rounded nodes bordering the venter on tlie re-<br />

fleeted part. <strong>The</strong> ribs <strong>of</strong> the straight part tend to be widely spaced.<br />

Variations from the typical form are common. <strong>The</strong> height <strong>of</strong> the<br />

tubercles and the distinctness <strong>of</strong> the obcure primary ribs on the living<br />

chamber, the relative coarseness <strong>of</strong> the ribs, and other characters vary<br />

with different individuals. <strong>The</strong> suture is the normal scaphite suture,<br />

with the ventral lobe largest and the others progressively smaller; the<br />

first lateral lohe is alxays bifid.<br />

Ren~arks.-This species is a cosmopolitari form that has been noted<br />

in western Europe and North Africa, and in the Gulf region and the<br />

Western Interior <strong>of</strong> the IJnited <strong>State</strong>s. <strong>The</strong> writer agrccs with Gabh<br />

that Scaphites rc?liforn~is Morton is mobt likely a juvenile <strong>of</strong> S. hippocrepis<br />

and disagrees with Weller that 9. sin~ilis IVhitfield is to be<br />

Description.-This species attains a large size, individuals approaching<br />

500 mm. having been recorded. <strong>The</strong> venter in the largest individuals<br />

is rounded, but even at a large diameter the ventral trnncation<br />

characteristic <strong>of</strong> the genus is still observable. <strong>The</strong> shell at all<br />

stages is relatively compressed, the flanks gently convex, the umbilicus<br />

very small. Whitfield states that he saw no nodes on the flanks, but<br />

Rlorton records umbilical tubercles and Hyatt writes <strong>of</strong> three rows <strong>of</strong><br />

t~ribercles on smaller specimens, umbilical, two-thirds the distance out<br />

from the umbilicus on the flank and distantly spaced, and on the margin<br />

<strong>of</strong> the venter. Hyatt describes the ventral tubercles as large and<br />

elongated parallel to the venter; Weller clescribes them as alternate.<br />

<strong>The</strong> larger individuals are essentially smoot,h. <strong>The</strong> suture is much dissected,<br />

with long elements, ranging from long and narrow to more<br />

solid and rounde(1. <strong>The</strong> ar~alogons species in the Westcrn lntcrior is<br />

P. nleeki Hoehm (zuhitfieldi ETyatt), hnt mceki is more compressed, the<br />

ventral truncation is narrower and lilore persistent, nodes are lacking<br />

on the flanks, and the suture is more con~ples.<br />

Rc~i~arks.-Much confusion has existed in the literature becanse <strong>of</strong><br />

a long-standing tencleney to assign all species <strong>of</strong> Placentieeras to plncenta.<br />

IIyatt's work has helped to correct this tendency, but bcca~~sc<br />

<strong>of</strong> his habit <strong>of</strong> discussing rather than (lcscribing features? some <strong>of</strong> it is<br />

difficult to follow, <strong>The</strong> species place~~tr~ is relativelp frequent in the<br />

olrler horizons, the Nerchantville clay-according to \fTellcr-provirling<br />

the most and best specimens. Those from othcr horizons arc more<br />

fragmentary and smaller.<br />

<strong>The</strong> specimen here illustrated is accompanied by a label indicating<br />

t,hat it was figured by Ibforton in his Synopsis (pl. 2, fig. 1). Out <strong>of</strong> hand<br />

the specimen does not look like Morton's figure, as the latter shows no<br />

defects and the specimen lacks all but the basal part <strong>of</strong> the living chamber,<br />

but Morton's figure is apparently much restored (as are those <strong>of</strong><br />

Ammonites vannxemi on the same plate, for which therc can he no<br />

question as to the original specimen). In size it fits the septate part<br />

<strong>of</strong> Morton's figure very well, for Morton says the specimen was 15<br />

inches in diameter, including a large part <strong>of</strong> the living chamber. <strong>The</strong><br />

opposite side <strong>of</strong> the specimen here ill~istrated was figurerl by Whitfield<br />

(his pl. 40, fig. 1).<br />

Description.-Collignon describes dclawarensk as a relatively thick<br />

ammonite with three stages <strong>of</strong> development-a young stage with three<br />

tnbcrcles on each flank; an intermediate stage bearing five tubercles<br />

on each Rank, <strong>of</strong> ~vhich the second tubercle from the umbilicus is small<br />

and pointed, the middle tubercle is large and on a strong rib, and the<br />

fourth and ventrolateral tubercles are elongated parallel to the ventral<br />

keel; and an adult stage, in which the tubercles except the umbilical<br />

and ventrolateral, weaken or disappear. In the adult stage the primary<br />

ribs are thick and massive, about 20 per whorl, concave forward. A few<br />

<strong>of</strong> these continue to the venter as simple ribs hut more frequently diyide<br />

at the middle tubercle to make about 30 ventrolateral ribs.<br />

Remarks.-<strong>The</strong> species dela~irarellsk has been noted in the litera-<br />

ture as widely distributed over the world in the eiirly Campanian. It has<br />

been conceived rather loosely, holvever, anct Collignonhas drastically re-<br />

stricted it. Zle has also made it the type <strong>of</strong> a subgenus <strong>of</strong> a genus based<br />

on a species from lladagasear. <strong>The</strong> material availal)le to the writer does<br />

not seem adequate to determine the validity <strong>of</strong> this procedure, but he<br />

has adopted it as the best procedure available and leaves to time the<br />

ultimate disposition <strong>of</strong> the questions involved.<br />

<strong>The</strong> three specimens figured hare all been previously illustrated by<br />

Whitfield, Weller, and Gardner and show three stages in development<br />

<strong>of</strong> the shell.<br />

shows 9 umbilical tubercles and 18 ventrolateral tubercles, with 3 more<br />

rows <strong>of</strong> tubercles on the fianks. Whitfield figures a second specimen<br />

about 55 mm. in diameter, on which, the ribs to about 40 mm. diameter<br />

show 5 rows <strong>of</strong> tubercles, and the latter part appears to have nearly<br />

lost the 3 rows on the flanks. From Whitfield's figure the dimensions <strong>of</strong><br />

Whitfield (1892, p1.42, fig. 9 ; p1.43, figs. 1-2) figures as Ammonites<br />

height <strong>of</strong> whorl <strong>of</strong> 90 mm. and width <strong>of</strong> 60 mm. A little more than one<br />

whorl is preserved and all <strong>of</strong> the early stages are missing. Only the<br />

umbilical and ventrolateral nodes are displayed, and the ribs are very<br />

weak. <strong>The</strong> keel is visible but sub~lned. Collignon (1948, fasc. 14, p. 30)<br />

large stage <strong>of</strong> S. vanztxemi, but as the authentic specimens <strong>of</strong> vam~cxenai<br />

<strong>The</strong> record <strong>of</strong> B. (T.) dentato-carinatic.m in <strong>New</strong> <strong>Jersey</strong> rests upon<br />

a single small fragment, about one-fifth <strong>of</strong> a whorl, with an estimated<br />

shell diameter <strong>of</strong> 50 mm. It was described and figured by both Whitfield<br />

and Weller. Its source is entirely unlmown, though it came to<br />

\Vhitfiel(l labelled as from the <strong>Cretaceous</strong> <strong>of</strong> <strong>New</strong> <strong>Jersey</strong> and still bears<br />

t,hat label. He attribvrted it tentatively to the "I~omcr Green Marls,"<br />

the modern A'a~rcsink marl, saying that limestone concretions in that<br />

formation have a similar lithology. Weller cites formation and locality<br />

as "Unknown, <strong>New</strong> <strong>Jersey</strong> (Whitfield)."<br />

Tl1e writer has clse\vhere (1932, U. S. Geol. Surrey Pr<strong>of</strong>. Paper 170,<br />

p. 10) expressed the opinion that the source <strong>of</strong> the specimen is so dubious<br />

that it should not be eonsidered. He also expressed the opinion,<br />

from descriptions and illustrations, that it is not destato-cari?latzc~n..<br />

Examination <strong>of</strong> tlie specimen itself and comparison with specimens <strong>of</strong><br />

similar size from Texas lead now to the opinion that it is authentic<br />

dentato-eorinatir.?)~ and that it is from Texas, not <strong>New</strong> <strong>Jersey</strong>. Three<br />

considerations lead to this conclusion: one, that the specimen is identical<br />

in minute details <strong>of</strong> morphology mith specimens from Texas and<br />

very similar in general appearance: though the color is a light tan rather<br />

than cream, and the matrix does not effervesce wit11 dilute hydrochlori(1e<br />

acid; two, that over the ~vorld the genus Rarroisieeras is found<br />

onlyin early Coniacian beds, which ~ ~~ould he well below the level <strong>of</strong> the<br />

Narcsink marl, and that nothing in tl~c earlier faunas, such as those<br />

reported from the Magothy formation, suggests this age; and three,<br />

the specimcn has a polish that snggests, as Morton reported for Baculitcs<br />

ounttis, long transportation as a pocketpiece before it came to rest<br />

in the collectioils <strong>of</strong> the Academy <strong>of</strong> Natural Sciences. It is, <strong>of</strong> course,<br />

perilous to press such evidence too far, but the writer believes it good<br />

enough to make the probability <strong>of</strong> the occnrrenee <strong>of</strong> B. dentatoearinatam<br />

in <strong>New</strong> <strong>Jersey</strong> very small.<br />

but, as is his habit, he describes specimens in minute detail hut nowhere<br />

actually defines the species. From his discussion it may be inferred that<br />

he had in mind ammonites that displayed no umbilical shoulder, had<br />

smooth flanks and compressed shells, and had a suture with abont five<br />

bilobed saddles, the remaining seven or eight being entire.<br />

species with some reservation, "a fragment <strong>of</strong> a cast * * * from Bir-<br />

sutures are different from those <strong>of</strong> any other form, having the ventral<br />

produced on pl. 1, fig. 2 is drawn only in its outline and so is unsuitable<br />

as the type specimen. Furthermore, this specimen could not be positively<br />

identified by the writer in the type-lot <strong>of</strong> Morton. This leaves the<br />

large specimen reproduced on pl. 1, figs. 1, 3 .as the only possible choice<br />

and this specimen is herewith salectccl as the leetot,ype <strong>of</strong> Belemnitel/a<br />

an~ericana (Morton). This very large guard, ~hich is actually the largest<br />

representative <strong>of</strong> Belc?~tn,itella americana (Morton) s. lato' seen by<br />

the writer, is reproduced on pl. 76, figs. la-le, as the original figures and.<br />

~lescription <strong>of</strong> Morton (1630a-e; 1834) arc somewhat imsatisfnctory.<br />

<strong>The</strong> original figure <strong>of</strong> RIorton (1830b, pl. 1, fig. I), however imperfect,<br />

shows clearly the asymmetry <strong>of</strong> the apical quarter <strong>of</strong> the guard and <strong>of</strong><br />

its mucro in the ventral aspect. This asymmetry is actually present on<br />

t,he original specimen and is clearly ~isible on pl. 76, figs. la, le. This<br />

puts the identification <strong>of</strong> the leetotype <strong>of</strong> R. an~nricana (Morton) heyond<br />

any donbt in the opinion <strong>of</strong> the writer. It is fclt, however, that<br />

this asylnmetry is pat,hologic;~l in its nature, as its appearance and a<br />

short and deep longitudinal groore associated with it are too irregular<br />

in their outline to be esplaincd in any other may. Besides, similar features<br />

only occur in the pathological (crippled) specimens in any hitherto<br />

described represontatires <strong>of</strong> the family Belemnitellidae Pavlom. <strong>The</strong><br />

sectioning <strong>of</strong> other specimens <strong>of</strong> Relei~lnitella aincricasa s. 1. and allied<br />

Xorth i\merican forms has sho~n that similar malformations are due<br />

t,o the juvenile guard having been broken and regenerated with subsequent<br />

loss <strong>of</strong> symmetry and normal proportions <strong>of</strong> the grown-up specimen.<br />

Even similar apical grooves hare becn observed sometimes. <strong>The</strong>rcfore,<br />

in spite <strong>of</strong> the fact that the guard has not been split, it seems safe<br />

to assuu~c that also the lcctotype <strong>of</strong> Belen~?~itclla at~lcrieana s. 1. has<br />

sulkred an injury <strong>of</strong> its juvenile g~~arcl (probably was broken) hut<br />

survivcd it and managed to hcal the fracture and to reach a very large<br />

(one could say gigantic as Belamnitella go) size.<br />

It is rather nnfortunate to have R pathological specimen for the<br />

lcctotype <strong>of</strong> Belo~l?litella antericonn (Morton) ; yet the writer does not<br />

see any escape route, the only figure <strong>of</strong> the ot,her specimen published<br />

simultaneously mit,h it being useless and the specimen itself apparently<br />

lost. Besides, the ahove described malformation is only a slight one and<br />

does not destroy or strongly distort the normal proportions <strong>of</strong> the<br />

guard or its external sculpture. Thus, it does not impair the usefulness<br />

<strong>of</strong> the leetotype as a type specimen once it is recognized as such. Apart<br />

from it the specimen chosen as lectotypc is almost complete, very well<br />

preserved, and quite typical <strong>of</strong> Rolentnitella amoricn@a s. 1. as nnderstood<br />

by the writer.<br />

Illorp11ology.-<strong>The</strong> description <strong>of</strong> the n~orphology <strong>of</strong> the guard <strong>of</strong><br />

Belemnitella americana s. I. is made rathcr difficult by the exceedingly<br />

great variability <strong>of</strong> almost all its morphological characters. <strong>The</strong> range<br />

<strong>of</strong> the variation is, in fact, so great that the writer is tempted to doubt<br />

that all the extreme morphological Hclcmnitella-like forms studied by<br />

him from the Mount Laurel sand and A'avesink marl <strong>of</strong> Ncm <strong>Jersey</strong> and<br />

their equivalents in Delaware and RIaryland are actually <strong>of</strong> one and<br />

the same variable species. Such doubts seem to find further support in<br />

the fact that most <strong>of</strong> the Belemnitclla collections studied by the writer<br />

from <strong>New</strong> <strong>Jersey</strong> and adjoining <strong>State</strong>s do not exhibit the mholc range <strong>of</strong><br />

the morphological variation presented by the sum total <strong>of</strong> the eollee-<br />

tions studied from the Mount Laurel sand and Navcsink marl <strong>of</strong> these<br />

three <strong>State</strong>s. This observation is, on the other hand, contradicted by the<br />

circumstance that there are several fossil localities in the <strong>State</strong>s <strong>of</strong> <strong>New</strong><br />

<strong>Jersey</strong> and Delaware where all, or nearly all, morphological forms <strong>of</strong><br />

Belemnitella described below as the varieties <strong>of</strong> B. americana s. I. occur<br />

together and appear to intergrade with one another. Nor isas it pos-<br />

sible to establish any regular changes in the composition <strong>of</strong> the Belenlr<br />

ititella fauna within the sncccssion <strong>of</strong> beds <strong>of</strong> the IIount Laurel and<br />

Navesink formations. If me further consider that aceorcling to Urey<br />

et al (1951, pp. 413, 415) the Xcw <strong>Jersey</strong> occurrences <strong>of</strong> Bele~rniitella<br />

represent partly or wholly (7) the postmortem concentrations <strong>of</strong> bhe<br />

guards in the shallolv and agitated waters, the above discussed varia-<br />

tions in the ranges <strong>of</strong> morphological variation observed from one lo-<br />

cality to another may well be due solely to the postmortal sorting <strong>of</strong><br />

specimens, according to their size and shape, 11y waves and currents.<br />

As most <strong>of</strong> the collections studied bave not been collected bed by<br />

bed, and as, consequently, there is no detailed information about the<br />

stratigraphical ranges <strong>of</strong> the various morphologically distinct Belem-<br />

nitella forms present in the collections studied, the writer prefers to<br />

treat them all as mere morphological varieties <strong>of</strong> one and thc same vari-<br />

able (= "polytypic") species Belemnitella americana s. 1. <strong>The</strong>se va-<br />

rieties are described in the following pages. In some extreme cases the<br />

writer's doubts about the varietal status <strong>of</strong> the forms concerned are<br />

expressed informally in their description.<br />

<strong>The</strong> grouping <strong>of</strong> the representatives <strong>of</strong> the species according to the<br />

outline and proportions <strong>of</strong> the guard has been found to be the best<br />

solution <strong>of</strong> the intricate problem <strong>of</strong> organization <strong>of</strong> the numerous mor-<br />

phological forms referable to B. a~nericana s. 1. In distributing the<br />

guards among the varieties it has been found necessary, however, to<br />

talrc into nccount the valne <strong>of</strong> the Schatsky IndexL, the appearance <strong>of</strong><br />

the apical end <strong>of</strong> the guard and the degree <strong>of</strong> its mucronation, the depth<br />

<strong>of</strong> the alveolus, and the degree and the character <strong>of</strong> the sculpture cover-<br />

ing the surface <strong>of</strong> the guard.<br />

Introduction.-Belentnitclla alnerica~la (3Iort.) var. a~noricnna nor.<br />

var. is morphologically intermediate between the estre~ne varieties <strong>of</strong><br />

the species described belom.<br />

It is also hy far the 111ost common variety <strong>of</strong> B. amerieana (Morton)<br />

s. I. in almost ill1 fossil lots <strong>of</strong> the species studied by the writer from<br />

<strong>New</strong> <strong>Jersey</strong>, Delaware, and Maryland. <strong>The</strong>refore B. anlericana var.<br />

amevicana may appropriately be eonsiclered as typical <strong>of</strong> the species,<br />

all the more so as thc above discnssed leetotype <strong>of</strong> R. a~aericana s. I. is<br />

its typical representative.<br />

Morphology: Guard generally large, this variety including nearly<br />

all the largest specin~ens <strong>of</strong> 1). a,n~erica?ra s. I. known to the writer. In<br />

its proportions the guard fluctuates from long an11 n~odcrately sturdy<br />

to short and stout. <strong>The</strong> extremes known to the writer are reproduced<br />

on pl. 77, fig. 2a-2b; pl. 78, fig. 4a-411: 111. 79,. figs. la-lb, 6a-6c. In<br />

the majority <strong>of</strong> the specimens studie[l the guaril in (.he lateral aspect<br />

tapers gradually and evenly all thc may from its alvcolar edge to a<br />

point some 10-30 mm. above its apical end. From this point the tapering<br />

increases more or less strongly, mith its second increase <strong>of</strong>ten occurring<br />

just hefore the apical end <strong>of</strong> the guard (see pl. 76, fig. la,<br />

Id; pl. 77, fig. 2b). <strong>The</strong>se increases in tapering produce more or less<br />

vide or narrow but alvays more or less rounded and obtuse apieal<br />

ends mith or without a clearly defined mucro. Somewhat more rarely<br />

the guard tapers at the same or almost the same rate to its very end,<br />

nVhieh thus becomes very narrow, long and acute (see pl. 79, figs.<br />

la-lc) and mostly but feebly mucronate. In other rare instances the<br />

guard does not perceptibly taper apically over the anterior third or half<br />

<strong>of</strong> its length, remaining virtually subcylindrieal throughout this section,<br />

(see p1.79, figs. 2,3a, 6a-6c). In such instances, howt:ver, the guard<br />

nearly always tapers more or less pronouncedly over its posterior half<br />

or two-thirds.<br />

In the rentral aspect the guard is mostly subcylindrical to feebly<br />

conical from its alveolar edge to a point 25-50 mm. above its apieal end.<br />

Below the said point thc tapering toward the apical end <strong>of</strong> the guard<br />

increases markedly producing a more or less rounded and obtuse end <strong>of</strong><br />

the guaril with or ~vithout a clearly defined mucro (see pl. 76, figs. la,<br />

lc; pl. 77, figs. 2a-c ; pl. 78, fig. +a). In the remaining minority <strong>of</strong> specimens,<br />

however, the vcntral outline <strong>of</strong> the guard raries from a markedly<br />

conical shape with or ~x.itliout ;L strongly rounded apical end and well<br />

(lefined mucro to somewhat li~necolate shape with a fairly olituse and<br />

NEW JERSEY GEOLOGICAL SURVEY


ounded short apical entl with or without well defined muero (see pl.<br />

77, fig. 3a; pl. 79> fig. Ga). <strong>The</strong>se estrcmes <strong>of</strong> the ventral outline <strong>of</strong> t,he<br />

guard connect 11. aa~ericnlia rar. anlerica?~~ wit11 L-'. n~rlei.icana var.<br />

and also with the younger species E. ef. bz~lbosa Afcclc and Hayden.<br />

In the majority <strong>of</strong> the specimens studied, the ventral i~nd dorsal<br />

sides <strong>of</strong> the guard are fairly to very strongly flattened, either tl~roughout<br />

their entire length or? at least, hctweeu the base <strong>of</strong> the ventral fissure<br />

and the apical end <strong>of</strong> the guard. This flattening generally increases<br />

gradually tolr.ard the apical end <strong>of</strong> the guard and results in the<br />

pronouncedly oval cross sections <strong>of</strong> the guard all over its posterior half<br />

to two-thirds (see pl. 7G> fig. le; pl. 77, fig. 3c; pl. 79, figs. ld, 3h, 5b).<br />

Tile dorsal side <strong>of</strong> the gaartl is <strong>of</strong>ten more strongly flattened than the<br />

ventral side. In a number <strong>of</strong> guards, including the leutotype <strong>of</strong> the<br />

species, it is virtually flat (see pl. 76, fig. le; pl. 79, figs. Id, 3b). 'rhe<br />

xrentral side <strong>of</strong> the guard only rarely beco~ncs con~pletely flattened. <strong>The</strong><br />

dorso-ventral diameter is comluonly larger tl~an tlie lateral diameter at,<br />

the base <strong>of</strong> tlie alveolar fissure and further orad. <strong>The</strong>re are, ho~ve~er,<br />

quite a few guards in which this relationship is reversed, and some<br />

with hot11 diameters virtually equal. As t,he allore (leserihed dorsoventral<br />

flattening <strong>of</strong> t,he guard is accomp;~nic(l 11y its market1 (lorsoventral<br />

compression below the level <strong>of</strong> (,he alveolar fissure, the dorsoventral<br />

diameters are alrvays markedly less than the lateral ilialneters<br />

at the same levels throaghout this part <strong>of</strong> t,hc guard (see pre\rio~isly<br />

listed cross sections <strong>of</strong> the guard). Tn tho ~najority <strong>of</strong> the specimens the<br />

cross section <strong>of</strong> the guard at its alveolar rim is either almost perfect,ly<br />

round or feebly oval with the lateral di;lmeter still somewhat exceeding<br />

the dorso-ventral cliameter. In rarer instances the dorso-ventral iliameter<br />

sligl~tly cseeeds the lateral one at the alveolar rim. Even in these<br />

instances, ho~vever, this relationship <strong>of</strong>ten bccornes reversed above the<br />

level <strong>of</strong> the base <strong>of</strong> the ventral fissure. <strong>The</strong> other more common estremc<br />

is represented by the guards 1aBie11 are pronouncerlly (lorso-ventrally<br />

flattened and colnpressed even at their t~lvcolar rim. <strong>The</strong> leetotype <strong>of</strong><br />

the species (see pl. 76, figs. la-lcl) sl~o\~s this relationship.<br />

Over the anterior two-t,hir(ls to three-quarters <strong>of</strong> the length <strong>of</strong> the<br />

guard its markedly flattened dorsal surface is situated between t,hc<br />

dorso-lateral depressions <strong>of</strong> the nsnal Eclemnitellidac type. At their<br />

bottoms these depressions commonly earry indistinct cloahle dorsolateral<br />

furrows (or secondary depressions) separated 11y ;I lorn longitudinal<br />

ridge. Ilorso-lateral depressions run generally longitudinally<br />

but they converge more or less marlredly toward the median plane <strong>of</strong><br />

the dorsal surface <strong>of</strong> the guard as they approach its alveolar rim. This<br />

gradually reduces the width <strong>of</strong> the flattenccl ilorsal side <strong>of</strong> the guard<br />

over its alveolar third. <strong>The</strong> ilorso-lateral ~leprcssions gradually become<br />

shallower apically unt,il they finally (1isal)pear ~vithin the apical third<br />

or quarter <strong>of</strong> the lellgtll nf t,he guard. Furthermore: the (loltble dorso.<br />

lorn and narrom, in the same direction. Over the apical third or quarter<br />

<strong>of</strong> the length <strong>of</strong> the guard these double dorso-lateral furroms are cut<br />

directly into the more or less regularly rounded flanks <strong>of</strong> the guard ;<br />

they run slightly obliquely toward the ventral side <strong>of</strong> the guard and<br />

gradually approach the lateral position toward its apex, not quite reaching<br />

this position just before their final disappearance on the obtnse<br />

part <strong>of</strong> the apical end <strong>of</strong> the gnard some 5-15 mm. above its mucro.<br />

11s a rule, the dorso-lateral donhle furrows are ahout 0.3 to 0.6 mm.<br />

wide and are separated by a low ridge some 0.5 to 1.0 mm. wide; in<br />

the majority <strong>of</strong> instances they run quite or almost parallel and straight.<br />

In some 15.20% <strong>of</strong> the guards studiecl, however, their course becomes<br />

wavy or quite irregular on one or both sides <strong>of</strong> the guard, or one or thc<br />

other furrow departs from its normal direction. Also the total disappearance<br />

<strong>of</strong> the double dorso-lateral furrows in a maze <strong>of</strong> branching<br />

vascular imprints and strong longitudinal furrows and striae has been<br />

observed in several instances (e.g. on both flanks <strong>of</strong> the lectotype <strong>of</strong> the<br />

species, see pl. 76, figs. la, lc). <strong>The</strong>se irregularities are, however, believed<br />

to be either pathological in their nature (e.g. in the lectotype)<br />

or caused by the very strong development <strong>of</strong> the vascular imprints and<br />

longitudinal striae, which obscure or distort the normal Belemnitellnlike<br />

character <strong>of</strong> the double furrow in the adult age.<br />

<strong>The</strong> main vascular imprints on the lower third or quarter <strong>of</strong> the<br />

gnard tend to branch <strong>of</strong>f the double dorso-lateral furro~vs undcr acute<br />

angles averaging 15-25' and not exceeding 30' (Belenmitella-like type<br />

<strong>of</strong> branching). Thcre are numerous instances, hoxever, when at least<br />

some <strong>of</strong> these main branches either become quite irregular in their<br />

course or branch from the double dorso-lateral furrows at angles exceeding<br />

30". Generally speaking these instances coincide with the previously<br />

described cases <strong>of</strong> the abnormal development <strong>of</strong> the furrox\.s<br />

themselves. <strong>The</strong>refore they are helicred to be mainly or totally due to<br />

pat,hological causes or to the excessively strong development <strong>of</strong> the<br />

vascular imprints and longitudinal striae.<br />

In the majority <strong>of</strong> the adult specimens <strong>of</strong> the variety the surface<br />

<strong>of</strong> the guard is fairly to very strongly sculptured by dense and pronounced,<br />

somewhat irregular, longitudinal striae and furrows, and<br />

with an equally pronounced and very dense net <strong>of</strong> ramifying vascular<br />

imprints. <strong>The</strong> crossing <strong>of</strong> both t,yl)es <strong>of</strong> sculpture prodnces a coarse and<br />

irregular granulation which covers parts or all <strong>of</strong> the surface <strong>of</strong> the<br />

guard. This granalat,ion is distinct from that <strong>of</strong> the Eurasian genus<br />

pl. 3, figs. la-lh, 2a-2b; pl. 5: figs. 6a-6b, 111. 6, figs. 4a-4b). As a rule, the<br />

above descrihed scnlptnre is most prououncedly expressed on the anterior<br />

half <strong>of</strong> the guard. <strong>The</strong> granulation is for the most part completely<br />

or mainly restricted to it. On the posterior half <strong>of</strong> the guard<br />

NEW JERSEY GEOLOGICAL SURVEY


tile seolpture is niostly dominated by the longitudinal striae and furrows<br />

and the vascular imprints become somewhat less dense and less<br />

ramified. <strong>The</strong> strongly ohlique vascular imprints become predominant<br />

on tho flanks <strong>of</strong> the guard. Sometimes the longitudinal striae and forralvs<br />

almost completely suppress all other types <strong>of</strong> sculpture Over parts<br />

or all <strong>of</strong> the posterior half <strong>of</strong> the guard (e.g. pl. 76, fig. le ; pl. 77, figs.<br />

2a-c). A11 above described types <strong>of</strong> sculpture, including granulation,<br />

occur also inside <strong>of</strong> the dorso-lateral depressioas <strong>of</strong> the guard. It should<br />

also bc noted that the sculpture, and in particular the granulation, are<br />

particularly strongly developed on the ventral surface <strong>of</strong> the guard<br />

nronnd its ventral fissure.<br />

In some guards, otherxvise indistinguishable from B. americana var.<br />

'n~ericnnn, the seulpture <strong>of</strong> the ventral and dorsal sides <strong>of</strong> the guard<br />

becomes ~veakened over its posterior half. In a few other guards this<br />

xveakening <strong>of</strong> the sculpture progresses so far as to make the flanks and<br />

the ventral and dorsal sides <strong>of</strong> the guard appear semi-smooth all over<br />

its posterior half. Such guards are usually more slender and so appear<br />

to connect B. amcricana var. alnericana with feebly sculptured semismooth<br />

to almost completely unsculptured varieties B. amerieanu var.<br />

polifa and B. an~erieana var. intennedia. Another extreme is represented<br />

by the guards which are densely granulated all over their surface.<br />

<strong>The</strong> lectotype <strong>of</strong> the species (see pl. 76, figs. la-ld) and the more<br />

slender gnard reproduced on pl. 79, figs. la-le approach this extreme,<br />

as does the semi-adult guard on the variety reproduced on pl. 76, figs.<br />

6a-6h. It should be mentioned, however, that the poor preservation <strong>of</strong><br />

the guards <strong>of</strong> B. ancericu?ta s. I. <strong>of</strong>ten makes them appear semi-smooth<br />

or even almost smooth. With all such worn out or somewhat etched<br />

specimens weeded out, the semi-smooth or relatively feebly sculptured<br />

specimens are uncommon in B. americana var. americana.<br />

In the majority <strong>of</strong> the reasonably to almost complete guards <strong>of</strong><br />

B. anlerieana var. americana the depth <strong>of</strong> the alveolus approaches one<br />

third <strong>of</strong> the total length <strong>of</strong> the guard (see pl. 76, fig. 2, pl. 79, fig. 3a).<br />

In some rare specimens belonging to the most sturdy and short form<br />

<strong>of</strong> the variety, or in those transitional to B. antericana var. intermdia.<br />

the depth <strong>of</strong> the alveolus approaches two-fifths <strong>of</strong> the guard (see pl.<br />

79, fig. 6c). In other relatively more common specimens, which are<br />

mostly transitional to B. americana var. subfi~sifomis, B. americana<br />

var. lon.ga, H. an~ericana var. polifa, and B. ef. bulbosa Meek & Hayden<br />

in their other morphologieal features, the depth <strong>of</strong> the alveolus becomes<br />

reduced to one quarter <strong>of</strong> the total length <strong>of</strong> the guard. <strong>The</strong> alveol~~s is<br />

relatively narrow, its dorso-ventrally measured angle fluctuates between<br />

19' and 22" with the mean value around 20". On the dorsal side <strong>of</strong> the<br />

alveolus there is a longitudinal median furrow 2-3 mm. wide and 1-2mm.<br />

deep which is characteristic <strong>of</strong> all Belentnitello-like forms <strong>of</strong> the family<br />

with the doubtful exception <strong>of</strong> nelemnitella Itoefcri Schloenhaeh 1.867.<br />

This median furrow continues clo~vn~!~arcl almost to the embryonic bulb,<br />

gradually becoming more and more narrow and shallow in this diree-<br />

which is 0.25-0.5 mm. thick. Except for the above discussed longitudinal<br />

dorsal furrom and the sometimes preserved impressions <strong>of</strong> the<br />

chambers <strong>of</strong> the phragmaeone, the eonotheea appears to the nalted eye<br />

to be quite smooth. In the majority <strong>of</strong> the guards it is destroyed, holx7ever,<br />

with the exception <strong>of</strong> the apical part <strong>of</strong> the a1veo:ns. <strong>The</strong>refore<br />

Sometimes the ventral fissure reaehes the surface <strong>of</strong> the guard at the<br />

level <strong>of</strong> the embryonic bulh or even somcwhat below this latter. In<br />

some instances irregularly bent (see pl. SI): fig. 3a) or straight bottoms<br />

<strong>of</strong> ventral fissure running very ol)liquely ul)mard and forming angles <strong>of</strong><br />

only 5-lj0 15-it11 tl~e inner xvall <strong>of</strong> the alveolus (see pl. 77, fig. 5e) dso<br />

<strong>The</strong> median line ;11\~ays runs closer to the ventral side <strong>of</strong> the guard,<br />

being as a rule two-fifths <strong>of</strong> the thickness <strong>of</strong> the gnard away from this<br />

latter. Its course is com~nonly quite to almost straight within the anterior<br />

t,hrec-quarters <strong>of</strong> the postalveolar part, <strong>of</strong> the guard hut it deviates<br />

slightly toward t,llc median plane <strong>of</strong> the guard in the apical<br />

quarter <strong>of</strong> the same. <strong>The</strong>refore t,he rnrtcro nearly ;~l~vays lies within<br />

ihe median plane <strong>of</strong> the guard or eseeetlingly close to this latter.<br />

<strong>The</strong> alveolar fissure is always long in relation to the depth <strong>of</strong> the<br />

al~,eolus. In the majority <strong>of</strong> the guards studied it reaches well into the<br />

posterior third or quarter <strong>of</strong> the alreolns (pl. 79, figs. lc, 2, 3a, 6e, 7).<br />

Taxonomic Renfarks.-<strong>The</strong> form here dcsoibed as Belemnitelln<br />

nn~ericnna (Morton, 1830) var. subfnsiforn~is Whitfield, 1892, was<br />

first differentiated from the t,ypical Bolentnitellu untcricana by Morton<br />

(1834, p. 34, pl. 1, fig. 3) himself, who has considered it to be a variety<br />

<strong>of</strong> this species. In so far as Morton did not use the latinizctl form <strong>of</strong><br />

the word "subfusiform" either in the test or in the explanation <strong>of</strong> the<br />

figure, the name is clearly not a\.ailahle under thc Rules <strong>of</strong> Zoological<br />

Nomenclature from his Synopsis. Should it. be available, however, it<br />

would fall into synonymy <strong>of</strong> Belen~nites szcbfzisiformis Raspail, 1820,<br />

as both forms have been referred to the same genus Belc~n~~ites Lamarek,<br />

1799, by their authors.<br />

Whitfield (1892, p. 280, explanation <strong>of</strong> plate XLVII) was apparently<br />

the first to use Morton's informal name LLSubfusiform" in its<br />

latinized form ".sztbfii.siforii~is". 11e has also refigured the original<br />

specimen <strong>of</strong> Morton under this name. Accordingly Whitfield (1892)<br />

must he considered to be the author <strong>of</strong> this variety in spite <strong>of</strong> the fact<br />

that he has passed it into the synonymy <strong>of</strong> Belornnitella americana<br />

(Morton). In so far as this variety was referred by Whitfield to the<br />

genus Belemnitclla dlOrhigny 1842 and not to Belemnites Lamarck,<br />

1799, the name Belemnitella americana (Morton) Tar. subfusiformis<br />

Whitfield, 1892 does not become a junior synonym <strong>of</strong> Belernnites subfesiformis<br />

Raspail, 1829, \~hich, in the meantime, has hcen assigned to<br />

t.he genus llibolitos hlontford, 1808 (see Bulow-Trummer, 1920, p. 154).<br />

Type specimen.-<strong>The</strong> original specimen <strong>of</strong> Morton (ANSP 19488)<br />

hecomes the holotype <strong>of</strong> Belemnitella americana var. subfusiformis<br />

Whitfield by monotypy, as Whitfield has applied the name only to that<br />

specimen (pl. 78, figs. la-lc). <strong>The</strong> esact locality and the formation from<br />

which this and other <strong>of</strong> Morton's types <strong>of</strong> B. ainericanu have been col-<br />

lected are unknown.<br />

.Morphology.-Guard usually small to mcclium sized, its proportions<br />

vary from moderately short and sturdy (see pl. 78, figs. la-lc) to long<br />

and slender (see pl. 78, figs. 2a-2c). D. nn~ericana Tar. sz~bf~~siforntis<br />

is the smallest <strong>of</strong> all the known varieties <strong>of</strong> the species; all its largest<br />

representatives known to the mriter are transitional to II. anrericanu T~I..<br />

polita, B. americana var. longn, or to B. an~ericana var. americana. <strong>The</strong><br />

guard is normally pronouncedly to moderately lanceolate in its ventral<br />

aspect and feebly lanceolate, subcylindrical or very feebly subconical<br />

(rarely) in its lateral aspect (see pl. 78, figs. la-lc, 3a-3c; pl.<br />

BELEMNITIDAE 149<br />

to moderate (seldom) dorso-ventral flattening and compression<br />

occur thronghout the postnlveolar part <strong>of</strong> the guard, or rarely over<br />

its entire length, tending to increase in the posterior direction. <strong>The</strong>re<br />

are rare representatives <strong>of</strong> the variety, however, which almost lack any<br />

(lorso-ventral flattening and do not show any dorso-ventral compression<br />

at all (sce pl. 78, figs. 3a-3c). <strong>The</strong> maximun~ lateral diameter is<br />

llsually situated very low in the apical third <strong>of</strong> the guard, or in its<br />

apical quarter (see pl. 78, figs. la, 2;1). In the slender representatives<br />

<strong>of</strong> the variety, ho~vever: it may be situated much higher (see pl. 78, fig.<br />

as that <strong>of</strong> the double dorso-lateral fnrro~vs anrl thr: main vascular iinpressions<br />

not seem to sliow any material differenccs from those <strong>of</strong> lI. a~iiericoirn<br />

Tar. a~~tericana (see pl. '78, figs. lb-c, 2b-c, :3b).<br />

<strong>The</strong> dcpth <strong>of</strong> the alveolus varies very consiilerably in the spec' >imens<br />

studied; in the majority <strong>of</strong> specimens (e.g. pl. 78, figs. lc, 2c) its depth<br />

fluctuates bet\veen 20 and 30% <strong>of</strong> the total length <strong>of</strong> tlic gn;~rd (27%<br />

in the holotype). In some extreme cases, ho~vcrcr, the depth <strong>of</strong> the alveolus<br />

may decrease to 73.15% <strong>of</strong> the total length <strong>of</strong> the gnard (e.g.<br />

pL 78, fig. 3c).<br />

<strong>The</strong> \ralues <strong>of</strong> the SehatsLy Inclcs lie, as a ritle, between 2.5 and 3.5<br />

mm. In relatively rare instances, however, values <strong>of</strong> 1.5-2.5 mm. and<br />

<strong>of</strong> 3.5-4.5 mm. have also been observed.<br />

<strong>The</strong> values <strong>of</strong> the alveolar angle in the dorso-ventral plane fluctuate<br />

het~vccn 18" and 28' in specimens mliich could be aceiirately mcasurecl.<br />

<strong>The</strong> length <strong>of</strong> the ventral fissure in relation to the depth <strong>of</strong> the alveolus<br />

varies in about the same limits as that <strong>of</strong> B. a~~lericano wr.<br />

amoricana (see pl. 7S1 figs. la-lc; 2a-2c, 3a-3c; pl. 79, fig. 4). <strong>The</strong> fissure<br />

<strong>of</strong> B. antcricana var. suhfusifor)ni,$ is shorter, lio~vever, than that<br />

<strong>of</strong> R. americnna rar. antcricana in relation to the total length <strong>of</strong> the<br />

guard.<br />

<strong>The</strong> limits <strong>of</strong> the variation in the outline <strong>of</strong> l.11c ventral fissnre appear<br />

to be the same as in B. an~erica?ra Tar. a)rro.ica~ta. Contrary to this<br />

variety, horrcver, the do~~~n~\~ardly concave outline <strong>of</strong> its bottom with<br />

the ventral fissure rcaching the surface <strong>of</strong> tl~e guard only a few mm.<br />

above the level <strong>of</strong> its beginning on the inner \\.all <strong>of</strong> the alveolus (see<br />

in sonic 45-5070 <strong>of</strong> t,he specimens st.~~~lie(l. Tlie nest most common<br />

outline <strong>of</strong> tlie bottom is the S-like one (see pl. 78, fig. 2c). ~vliieli<br />

is also decidsdly uncommon in 11. anlovicuna vdr. illlle~iea?la. It ocel11's<br />

in some 10.15% <strong>of</strong> the speciulens studied. <strong>The</strong> irregularly bent outlines<br />

<strong>of</strong> the bottom (see pl. 79, fig. 4), with tlie fissiirc reaching the<br />

surface <strong>of</strong> the guard at about the lcvel <strong>of</strong> its beginning on the inner.<br />

H. f~iitericaaa rar. szibfzlsiformis than in B. ai~tcricnzla rar. a~~tcri(~a~rr<br />

It appears that the forms <strong>of</strong> B. americana var. sribfusifor~~tis possessing<br />

the more sliallow alrcolus, a typically laricet~late ventral outline<br />

<strong>of</strong> the gnard, and strongly flattened and co~npressc~l dorso-ventrally,<br />

forms appear to deser\.e a formal varietal n;~me, \vhich is not proposed<br />

here only because <strong>of</strong> the paucity <strong>of</strong> sufficiently well preserved<br />

and typical specimens <strong>of</strong> them in the material studied. Conversely, the<br />

stressed, however, that at least some juvenile guards <strong>of</strong> B. americana.<br />

.szrbfusiformis are indist,inguishable from the more slender and<br />

longer jnrenile guard types occurring in 1:. amoricana var. americana<br />

Dktribzitwn and Stratiprapi~ica' Runye.-Within the state <strong>of</strong> <strong>New</strong><br />

almost eyery one <strong>of</strong> the localities from which belemnite collections hare<br />

as Barnsboro and Glassboro, <strong>New</strong> Jerscy, and Reedy Point, Delaware,<br />

which is probably owing to t,he small amount <strong>of</strong> the gnards availahle<br />

(1 to 7) from these localities.<br />

that are transitional betmecn both groups <strong>of</strong> forms in this respect,.<br />

Also the pronouncedly laneeolate outline <strong>of</strong> its guard in ventral aspect<br />

and n~ostlyfeebly lanceolate outline in lateral nspeet readily distinguish<br />

R. an~ericann var. sabfiisifornlis from all other varieties with the eseeption<br />

<strong>of</strong> B. amcricana var. interntedia. This latter variety is, however,<br />

distinct from B. omoricana var. subfusiforz~lis in its greater value<br />

<strong>of</strong> the Schatsky Index, its much deeper alveolus, and in the acute, long:<br />

and almost nonmueronate outline <strong>of</strong> the apical end <strong>of</strong> its guard. <strong>The</strong><br />

shallower alveolus is also helpful in the differentiation <strong>of</strong> l3. antericann<br />

reproduced on pl. iii figs. 2a-2e, in the proportions and general outline<br />

<strong>of</strong> its guard, as well as in the obtuse, distinctly mucronate apical end<br />

<strong>of</strong> the same, and in the cl~aracter <strong>of</strong> the sculpture <strong>of</strong> the surface <strong>of</strong> its<br />

guard. It differs, hoxvever, in the greater length and slenderness <strong>of</strong> its<br />

guard, its lesser dorso-ventral flattening and compression, and in the<br />

much smaller value <strong>of</strong> its Sellatsky Index, which fluctuates from 3.0<br />

to 3.5 mm. in the specimens studied. It also seems to differ from R.<br />

americana var. americana and to approach closely B. americann var.<br />

s~abf~csiforiiais (see PI. 79, fig. 5a) in the character <strong>of</strong> its ontogenetic<br />

(levelopment.<br />

In the value <strong>of</strong> its Schatsky Index R. ainericana var. longa is very<br />

close tn 5'. amerieana Tar. polifa and R. americana var. sirbflasiformis.<br />

It is, furthermore, connected with H. amc?icana var. polita by semismooth<br />

intcrme~liate forms, like that reprorinced on pl. '77, figs. 4a-4c,<br />

and with tho slen(1er and long forms <strong>of</strong> R. americana var. ~mbfusiformi.~<br />

by int,ermcdiatc forms: like that reprodrrced on pl. '78, figs. 2a-2c. <strong>The</strong>refore<br />

this rariety appears to be an extreme development <strong>of</strong> the slender<br />

and feebly lanceolate forms <strong>of</strong> B. americana Tar. subfiisiformis (see<br />

p1 78, figs. 2a-2c). It differs from these latter forms in the considerably<br />

greater length and slenderness <strong>of</strong> its guard, in the regular and slow<br />

apical tapering <strong>of</strong> the lateral outline <strong>of</strong> this latter, in the regularly and<br />

feehly conical ventral outline <strong>of</strong> its guard, and in the greater amount<br />

<strong>of</strong> its dorso-ventral compression and flattening.<br />

<strong>The</strong> guard <strong>of</strong> R. anwricana var. longa differs sharply from that <strong>of</strong><br />

R. americana var. polita in its pronouncedly sculptured surface, markedly<br />

conical lateral and rent,ral outlines: and obtuse, short, and distinctly<br />

mucronate apical end.<br />

groups <strong>of</strong> forms are more strongly expressed, however, with the exception<br />

<strong>of</strong> the value <strong>of</strong> the Schatsky Index. <strong>The</strong> greater depth <strong>of</strong> the<br />

K. antericana var. sabfusiforn~is. its ontogeny would be similar to that<br />

<strong>of</strong> the two last mentioned varieties.<br />

B. unlericai~a var. polita is an extreme form <strong>of</strong> the species that appears<br />

to he closest to the slender semi-smooth forms <strong>of</strong> 13. a~nericana var.<br />

subfusifornris and <strong>of</strong> B. a~iaericai~a var. loaga on the one hand and to<br />

the extremely slender and most feebly sculptured forms <strong>of</strong> B. americana<br />

var. interinetlia on the other. It is connected by the numerous<br />

t,ransitional forms with the former two varieties but there do not seem<br />

t,o be any transitional forms between B. americana Tzar. polita and B.<br />

antcricnna var. intermedia with regard to the value <strong>of</strong> the Schatsky<br />

Index. This favors the idca that It. antoricana Tar. polifa is yet another<br />

extreme derclopinent <strong>of</strong> the group <strong>of</strong> forms surrounding B. americanrr<br />

rar. s~rbfnsifortitis and is not elose to B. atncricana rar. infarmedin.<br />

<strong>The</strong> guard <strong>of</strong> B. americana rar. polita. differs marlcedly from other<br />

fissure is long and reaches well into the lower third or quarter <strong>of</strong> the<br />

alveolus. <strong>The</strong> bottom <strong>of</strong> the ventral fissurc usually forms an angle <strong>of</strong><br />

30"-50" with the inner wall <strong>of</strong> the alveolus; it is either almost straight<br />

or has an S-like shape (see pl. 77, fig. le) in the specimens studied.<br />

Also sharply bent or rounded, concave downward bottoms <strong>of</strong> the ventral<br />

fissure have been noted in some specimens. Alveolus is deep and wide,<br />

it fluctuates between tnro-fifths and one-half <strong>of</strong> the total depth <strong>of</strong> the<br />

guard and the alveolar angle is from 20' to 23'. <strong>The</strong> Sehatsky Index<br />

fluctuates between 4.5 and 5.5 mm. <strong>The</strong> apical end <strong>of</strong> the guard is long,<br />

acute, and almost to quite devoid <strong>of</strong> amuero. <strong>The</strong> sculpture <strong>of</strong> the guard<br />

usually consists <strong>of</strong> relatively feeble and widely spaced vascular imprints<br />

and longitudinal striae. Often the guards become semi-smooth over<br />

part or all <strong>of</strong> the posterior half. <strong>The</strong> sculpture varies, however, from a<br />

type almost indistinguishable from that <strong>of</strong> the typical R. antoricanavar.<br />

atnericana to one approaching the semi-smooth specimens <strong>of</strong> R. amerieana<br />

var. longa (see pl. 77, figs. 4a-4c).<br />

<strong>The</strong> guard reproduced on pl. 77, figs. la-le is herewith designated<br />

as the holotype <strong>of</strong> B. americana var. intermetlia nov. var.<br />

<strong>The</strong> guards referable to B. antericana var. internledia closely resemble<br />

those <strong>of</strong> the short, sturdy varieties <strong>of</strong> R. a?)terical~a var. antericana<br />

(see pl. 79, figs. 6a-c, 7) and are connected with them by numerous<br />

transitional forms. Also forms transitional between B. a?ncricana var.<br />

intermedia and the slender forms <strong>of</strong> B. alnericanu var. americana are<br />

common in some lots. B. americana Tar. internledia differs, however,<br />

from B. americana var. a,acricana in its distinctly lanceolate shape in<br />

ventral and lateral aspects. It shows a marked contraction at about the<br />

level <strong>of</strong> the base <strong>of</strong> the ventral fissure. This contraction is follo~ved by<br />

a gradual and even, but marlredly increased expansion <strong>of</strong> the guard all<br />

the way up to its alveolar rim. This contraction and the anterior expansion<br />

<strong>of</strong> the guard are especially well marked in its lateral aspect;<br />

they result in the pronounced widening <strong>of</strong> the alveolar part <strong>of</strong> the guard<br />

which is characteristic <strong>of</strong> R. arnoricana Tar. intermedia (see pl. 77: figs.<br />

lb-lo). Also the much feebler sculpture <strong>of</strong> the surface <strong>of</strong> the guard, the<br />

lack <strong>of</strong> granulation, and the deep alveolus reaching from two-fifths to<br />

one-half <strong>of</strong> the total length <strong>of</strong> the guard distinguish B. americana var.<br />

intermedia from B. americana var. americana, although some <strong>of</strong> the<br />

forms <strong>of</strong> the latter variety may become indistinguishable from the<br />

former variety in these features. <strong>The</strong> extremely slender and distinctly<br />

mueronate forms <strong>of</strong> B. alaericana, var. americana like that reproduced<br />

on pl. 77, figs. 2a-2c, and on pl. 79, figs. la-ld, are also much more<br />

slender and longer than B. americana var. intermedia, apart from being<br />

pronouneedly mucronate and obtuse in their apical ends, mhieh is never<br />

the case in B. anaericana var. interr~~edia. <strong>The</strong>re are, however, numerous<br />

transitional forms connecting these forms with the slender representatives<br />

<strong>of</strong> B. amcricana var. intermedia, some <strong>of</strong> then1 occurring in the lot<br />

liSNRf 16287, together with the extreme slender forms <strong>of</strong> R. americana<br />

From Belemnitella amerieana var. A, the' guard <strong>of</strong> B. antericarza<br />

var. intermedia differs primarily in its feebly lanceolate outline in<br />

lateral and ventral aspect, and in its marked dorso-ventral flattening<br />

and compression. Otherwise the two forms are very similar.<br />

lateral diameter <strong>of</strong> the guard over the dorso-ventral one than in otl~er<br />

varieties <strong>of</strong> B. americana s. 1. <strong>The</strong> ratio, lateral (liameter/~lorso-ventral<br />

diameter is, in fact, only 12.0 to 10.0 at the point 23 mm. above the apical<br />

end <strong>of</strong> the guard and only 12.7 to 13.1 at the level <strong>of</strong> the base <strong>of</strong> the<br />

alveolar fissure, compared with thc respective ratios <strong>of</strong> 10.3 to 8.7 and<br />

11.5 to 12.2 for the typical 6. amcriccnla var. arnoricana specimen. In<br />

ndclition to the above feature the saicl guard is distinguislied by the insignificant<br />

length <strong>of</strong> its alveolar fissure, which only amounts to about,<br />

two-fift.hs <strong>of</strong> the depth <strong>of</strong> the alveolus, its unusually deep alveolus reaching<br />

almost one half <strong>of</strong> the total lengtll <strong>of</strong> the gnard, and in the very long<br />

has been considered preferable not to give a formal varietal name to<br />

may be partly due to its mode <strong>of</strong> preservation.<br />

<strong>of</strong> the sturily: short forms <strong>of</strong> R. nntericana var. antericil?~a. As srtch it<br />

incomplete in its alveolar part and appears to be some\rhat corroded<br />

It should also be considered that in the shape <strong>of</strong> its guarrl the specimen<br />

Arlihangelsky, 1912 (see Arkhangelsky, 1912, pl. IS,. figs. 20-21, pl. X,<br />

thought to embrace the Alount Laurel sand as well as the Navesink marl<br />

(see Groot, Organist and Richards, 1954, pp. 43,45) and not tlie 1lou11t<br />

Laurel sand alone as it was thought earlier (e.g. Stephenson, 1933 1<br />

Stephenson et al., 1942). This makes B. an~ericana s. 1. the third invertebrate<br />

Jeletzky, in Cobban 6; Reeside! 1953, pp. 1026-25). This is inclicated<br />

by the fact that the Exogyra cancellntn zonc carries ill Tenncssec (ser<br />

Remarks.-This is the second giant Enoplocl7~tia that has been<br />

found in the Americas, the first being E. (P.) zudkeri (JQ~itfield, 1880.<br />

p. 37, pl. 16, figs. 1 a-c; pl. 17, fig. 1 a; Upper Albian; Texas), a species<br />

with a strongly curved and tapered dactylus. <strong>The</strong> straight dactylar<br />

axis and coarse surface tnberculation <strong>of</strong> our species agree with the de-<br />

scription <strong>of</strong> E. (P.) image1 M'Coy (1849, p. 332 ; Senonian ; England) ;<br />

however, the dactylar teeth <strong>of</strong> M'Coy's species-which has never heen<br />

figured-are said to be less than their diameter apart.<br />

Description.-Carapace about one and fonr-fifths longer than higb ;<br />

branchial an6 pterygostomial fields rougliened with adpressed conicill<br />

granules. Median groove <strong>of</strong> rostrum narrow, lateral earinae transversely<br />

rounded, spinulate above, and cont~nned backward on the gastric<br />

field by two steadily diverging rows <strong>of</strong> oblique conical granules.<br />

Proximal slope <strong>of</strong> supraorbital spine long, spinulate, followed by a row<br />

<strong>of</strong> granules which parallels the row behind the lateral earina <strong>of</strong> t,he<br />

rostrum. Antennal field inconspicuously t,rilobed, the lobes convex rertically;<br />

distal edge <strong>of</strong> anterior lobe beaded, the two posterior lobes<br />

granulated medially. <strong>The</strong> antennal spine is replaced by a blunt tubercle<br />

at the antennal angle.<br />

Postcervical groove (e) broader and deeper than the other earapacal<br />

grooves. Cervical groove (e-el) barely areuate, rising to a point<br />

slightly below the level <strong>of</strong> the infraorbital spine. Anterior arm <strong>of</strong> hepatic<br />

groove (b~) deep and straight, posterior and lower arms shallow,<br />

the latter ascending to join (c). Antennal groove (b) angulated before<br />

the prominence omega (v), its proximal arm straight. u equilateral,<br />

lower border marked by a shallow groove.<br />

Abdominal terga dotted with small widely spaced punetae ; pleurons<br />

roughened with crowded soekets. A broad thickened rim horders the<br />

posterior margin <strong>of</strong> each pleuron; along the upper border <strong>of</strong> the pleuron,<br />

extending forward from the rim to the distal margin, there is a<br />

rounded and closely pitted ridge.<br />

Major chelae equal and symmetrical (WFIS 16947), elongateelliptical<br />

Renlarks.-<strong>The</strong> carapacc <strong>of</strong> Eloplopariu {labbi is rare and has not<br />

been described heret<strong>of</strong>ore. It is distinguishable from all other Coastal<br />

l'lain hoploparids by tlie absence <strong>of</strong> ridges and tubercles from t,l~e antennal<br />

field. Rathhitn (1926, p. 187) points out that tht! palms suggest<br />

those <strong>of</strong> If. te~~nessecnsis Rathbun; ho~~~ever, the palm <strong>of</strong> the latter<br />

species reaches its greatest height at tlio distal extremity, whereas in<br />

FI. gabbi it is highest betmeen the anterior quarter and third. <strong>The</strong> synt,ype<br />

palms are incomplete and represent small individuals. One <strong>of</strong><br />

them (ANSP 527) bears a small spine-not present on t,he other 22<br />

Remarks.-ProtocalLianassa mortoni is the commonest Upper <strong>Cretaceous</strong><br />

decapod in Xeu~ <strong>Jersey</strong>. <strong>The</strong> palms vary considerably in snrface<br />

texture, number and arrangement <strong>of</strong> tlie papillae and sockets and<br />

in the ratio <strong>of</strong> the length to the height. Dccort,icated specimens may<br />

look quite different from those retaining either the inner or the outer<br />

layer <strong>of</strong> the integument.<br />

In spite <strong>of</strong> these differences, two races <strong>of</strong> the species can be dist,inguished<br />

: race a-height to length ratio varies from 1 :1.32 to 1 :1.62<br />

for major palms, and from 1 :1.1 to 1 :1.28 for minor palms; race b-<br />

rat,io for major palms is 1 :1.19 to 1 :1.25, and 1 :1.35 to 1 :1.48 for minor<br />

palms. Race a is the commoncr <strong>of</strong> the two, at least in <strong>New</strong> <strong>Jersey</strong> where<br />

it is particularly ahundant in the JIerchantrille formation. <strong>The</strong> syntype<br />

hands described by Pilsbry (1001, pl. 1, figs. 1-4, 8-10) belong to<br />

race a. Sixteen <strong>of</strong> tlie 442 <strong>New</strong> <strong>Jersey</strong> and Dclalvare specimens studied<br />

by tlie writer are race b indivirluals, as are the following:<br />

1) broad palms from A'e~r. <strong>Jersey</strong>, Delaware and Maryland cited<br />

by Pilsbry (1916, p. 365) ;<br />

2) bolotype <strong>of</strong> Cnlliai~assa. clnrki Pilsbry (1916, p. 368, p1. 11,<br />

fig. 8) ;<br />

3) specimens figured by Rathbun (192fi> p1. 67, figs. 1, 4-9) from<br />

Coon Creek beds in Tennessee.<br />

Both races range from Aferchantville age to Tinton age. Although race<br />

b hands are rare in Xelv <strong>Jersey</strong> and Delaware, to the south in Tenncs-<br />

see and Tvfississippi they appear to be the predominant form.<br />

Rathbun's (1935, p. 30) record <strong>of</strong> this species in the Woodbury<br />

pair <strong>of</strong> articular nodes <strong>of</strong> which the lower node twists inward and np-<br />

ward at the tip. <strong>The</strong> form <strong>of</strong> the wrist is oval-spheroidal wi1.h a large<br />

facet on the inner side. <strong>The</strong> proximal half <strong>of</strong> this facet serves as the<br />

articular surface <strong>of</strong> the carpomeral joint. Two grooves mark the outer<br />

surface <strong>of</strong> the wrist; one extends longitudinally across the mi(lclle, the<br />

Rathbun (1935, pl. 10, fig. 18 only) identified with Tetracoreinus sub-<br />

described here. However, her specimen is more elongated and the<br />

groove along its outer surface is at the middle rather than itt the upper<br />

third. It should be noted that Rathhun's figure 18 is retouched, giving<br />

the impression that the posterior margin <strong>of</strong> the hand is present and that<br />

its upper and lower posterior angles are rounded. Actually, the poster-<br />

<strong>The</strong>se are :<br />

PLANTS. Those <strong>of</strong> the Raritan formation \\.ere fully deseribe(1 I)y<br />

Berry (1911) and little work has been done suhseq~~ently other than a<br />

critical analysis by Dorf (1952).<br />

FORil~ITNIFERA. This group <strong>of</strong> <strong>fossils</strong> was included in the original<br />

edition <strong>of</strong> \\Teller, the work largely being taken from Hagg<br />

(1898). <strong>The</strong> a~lrances in the fielcl <strong>of</strong> mieropi~leontology have made much<br />

<strong>of</strong> this work obsolete and it therefore seems unlvise to reprint this seetion.<br />

Little work has been pnblishe(1 on the <strong>Cretaceous</strong> foraminifera <strong>of</strong><br />

<strong>New</strong> <strong>Jersey</strong> (luring recent years. Jcnnings (1936) described some<br />

speeies from the Cretaeeous and Eoeenc, and Cnshman (1948) described<br />

a <strong>Cretaceous</strong> fauna from 3Iaryland inclnding species uvhieh almost<br />

certainly occur also in <strong>New</strong> <strong>Jersey</strong>. <strong>The</strong> foraminifera <strong>of</strong> the Vincentown<br />

formi~tion, inclu~led with the <strong>Cretaceous</strong> by Weller hut now<br />

regar~lecl as Eoeene, have been discussed by R1eLe;ln (1952,1953).<br />

BRyOZO1l. No species <strong>of</strong> Rryozoa 11ave been reported from the<br />

true Cretaeeous <strong>of</strong> <strong>New</strong> <strong>Jersey</strong>. <strong>The</strong> extensive fanna <strong>of</strong> the Vineentown<br />

formation, included in \\Teller's original volume, is now thought to be<br />

<strong>of</strong> Eocene age. A thorough discussion <strong>of</strong> this fauna was given by Canu<br />

and Bassler (1933).<br />

OSTRACODA. Only ;I few ostraeotles have been reported from the<br />

<strong>Cretaceous</strong> <strong>of</strong> <strong>New</strong> <strong>Jersey</strong> although it is know that they occur in scvera1<br />

<strong>of</strong> the formations. Sonre ost,racodes from the Cretaeeor~s <strong>of</strong> nearby<br />

Delaware and Maryland have l~een discussed by Schmidt (1948) and<br />

Svain (1948).<br />

I~ISII. Thc most eo~nplete ~vorlr on the fossil fish <strong>of</strong> the Cretaeeol~s<br />

and Tertiary <strong>of</strong> <strong>New</strong> Jcrscv is that <strong>of</strong> Fowler (1911). Unfortunately,<br />

many <strong>of</strong> the locality records are very vague and it is therefore difficult<br />

to correlate the <strong>fossils</strong> \vit,h exact formations. <strong>The</strong>se reeords are furtl~er<br />

eomplieated by the fact t,l~at the Hornerstonn formation at that time<br />

mas regarded as <strong>Cretaceous</strong>. 3Zany <strong>of</strong> the specimens are merely referred<br />

<strong>Cretaceous</strong>, a number <strong>of</strong> species have been found in true <strong>Cretaceous</strong><br />

localities such as Maple Shade, Mullica Hill, Holmdel, ete. <strong>The</strong> most<br />

frequent genera are Lan~na, Isurus, Otodus, Coraz, Carcliarhinns<br />

(Glyphus) and ilemipristis. Other fish from the <strong>Cretaceous</strong> <strong>of</strong> <strong>New</strong><br />

<strong>Jersey</strong> include the following genera: Pyenodus, EnckotEt~s, an11 1st.hyvhiza.<br />

BIRDS. Eight species <strong>of</strong> birds mere described from the <strong>Cretaceous</strong><br />

deposits <strong>of</strong> <strong>New</strong> <strong>Jersey</strong> by Marsh. Six <strong>of</strong> these, Gracalauis ucloz, G.<br />

puntilus, Telmrornis priscus, T. affinis, Palaeotringa littoralis and<br />

P. vagans, were from the Hornerstown formation. P. vetus was from<br />

Arneytown and Laornis eduarsianus war; from Birmingham. Wetmore<br />

(1930), following the removal <strong>of</strong> the Hornerstown formation from the<br />

<strong>Cretaceous</strong> to the Eocene, suggested that these birds mere <strong>of</strong> Eocene<br />

rather than <strong>Cretaceous</strong> age. No specinlens <strong>of</strong> fossil birds have been<br />

found during recent years.<br />

BORINGS IN NEW JERSEY<br />

In 1951, the Transcontinental Gas Pipe Line Corporation drilled<br />

a series <strong>of</strong> test wells in Burlington and Ocean Counties, <strong>New</strong> <strong>Jersey</strong>,<br />

in an attempt to locate a buried structure suitable for the storage <strong>of</strong><br />

natural gas. Through the courtesy <strong>of</strong> George Grow, geologist with that<br />

company, and Meredith E. Johnson, former <strong>State</strong> Geologist <strong>of</strong> Nc\v<br />

<strong>Jersey</strong>, 1 have been permitted to examine the <strong>fossils</strong> obtained from<br />

these borings. A preliminary report on the <strong>fossils</strong> was given before the<br />

International Geological Congress in Ilexico City in 1956 (Richards<br />

1957-1959), while a complete list <strong>of</strong> the species will be puhlished clsehere.<br />

<strong>The</strong> <strong>Cretaceous</strong> <strong>fossils</strong> obtained from the cores include 48 spccics<br />

<strong>of</strong> which twelve are described as new. Notes and figures <strong>of</strong> a few species<br />

not hitherto reported from the <strong>Cretaceous</strong> <strong>of</strong> <strong>New</strong> <strong>Jersey</strong> are inclutled.<br />

In addition, a new species <strong>of</strong> the echinoid A't~cleop~gus (9) from the<br />

Navesink formation at Mullica IIi11, N. J. is described.<br />

<strong>The</strong> approximate location <strong>of</strong> the wells mbicl~ yielded the most significant<br />

<strong>fossils</strong> is as follows:<br />

1. 2 miles north <strong>of</strong> Chats~vorth, Burlington County<br />

2. 2.5 miles north <strong>of</strong> Chatsworth<br />

Ostrea ratitanensis lliehards n. sp.<br />

Plate 93, Fignres 13, 14<br />

Shell small, laterally areuate. IIinge-line slightly curved. Shell<br />

marked with from seven to ten deep plieations which extend inward<br />

from the lower or convex margin but do not reach the opposite side.<br />

NEW JERSEY GEOLOGICAL SURVEY


APPENDIX C 203<br />

Very faint plieations on the anterior hinge extremity which do not<br />

connect with the larger plications <strong>of</strong> the opposite side. <strong>The</strong> central<br />

portion <strong>of</strong> the shell is relatively smooth, without conspicuous rihs or<br />

plications. <strong>The</strong>re are faint indications <strong>of</strong> concentric groxth lines and<br />

very faint radial rihs near the beak.<br />

Ostrea raritanensis differs from the common <strong>Cretaceous</strong> 0. falcafa<br />

biorton by its much less conspicuous plications which do not extend<br />

across the shell. Also, 0. raritanensis is smaller in size and is more<br />

point,ed at the posterior end than in the case <strong>of</strong> 0. falcata.<br />

Dimensions: Length 9 mm., midth 3.1 mm., thickness 1.6 mm. (holo-<br />

Several specimens from Core 16 at 1648 feet appear to he identical<br />

with this species originally described from the <strong>Cretaceous</strong> <strong>of</strong> Texas.<br />

G. aucella is closely related to G. convcza (Say) and may actually be<br />

a variety.<br />

Crenella growi Richards n. sp.<br />

Plate 93, Figure 15, 1.6<br />

Shell small, inflated, slightly longer than high, subeqnilateral, equi-<br />

valve. All margins arched. Hinge typical <strong>of</strong> the genus. Beaks moder-<br />

ately prominent, incurved and located at the center. Onter surface<br />

ornamented with smooth closely spaced radial rihs numbering about<br />

10 to the millimeter at the ventral margin. Interspaces cut by fine eon-<br />

centric threads.<br />

Crenella grolci differs from C. .subcirci~laris Stephenson from the<br />

Woodbine <strong>of</strong> Texas in that it is much more rounded and shows both<br />

concentric and radial sculpture.<br />

Calliornphalus oceanicus Richards n. sp.<br />

Plate 94, Figures 1, 2, 3<br />

Shell small, nacreous, rather depressed, typically troehoid in shape<br />

and umbilieate; spire low; whorls four or five, rounded, sutnres im-<br />

pressed, circular in cross section ancl gradually increasing in size;<br />

protoconeh relatively flat. Sculpture <strong>of</strong> about 19 spiral nodulose<br />

ribs; tubercles arranged in parallel axial rows which are crossed b,v<br />

faint spiral-shaped ridges, giving a somewhat cancellate appearance to<br />

the shell ; suture slightly impressed ; subsutural rib strong ; aperture<br />

subcircular; umbilicus broad, umbilical heel tuberculate.<br />

Calliomphalas oceanicus differs from C. americanus Wade from thr:<br />

Ripley formation <strong>of</strong> Tennessee (Coon Creek) in that it has a lower<br />

spire, and more strongly cancellate sculpture. C. oceaniclcs lacks the<br />

conspicuous nodes surrounding the umbilicus as in C. antericanus.<br />

Dimensions: Height 6.9 mm. ; width 9.5 mm. (holotype).<br />

Locality: Boring 16 (1648 feet) RARITAN formation.<br />

Halotype: ANSP 30438; also 8 paratypes, badly crushed.<br />

Named from Ocean County, <strong>New</strong> <strong>Jersey</strong>, in which the well was lo-<br />

Tuba ( ?) fontis Richards n. sp.<br />

Plate 94, Figures 5, 6<br />

Shell <strong>of</strong> medium size, spiral but broacl at base, spire acute, whorls<br />

seven, convex and circular in cross section increasing in size toward<br />

the aperture; apical whorl very small. Sculpture consists <strong>of</strong> beaded<br />

spiral threads <strong>of</strong> unequal size, with two very eonspieuous rows on spiral<br />

whorls, but with five or more on the body whorl; beaded etiect <strong>of</strong> threads<br />

produced by numerous narrow sharply elevated axial lines across the<br />

crests <strong>of</strong> the spiral ridges. Suture distinctly impressed; aperture ap-<br />

parently circular; lip not distinct.<br />

Tuba ( 9 ) fo?~t&s differs from T. parabella Wade from the Ripley<br />

format~on at Coon Creek, Tennessee, by its less eonspieuons oruamentation,<br />

its fewer spiral ribs, and by having one less whorl. It is also<br />

considerably smaller than T. parabella. It is placed in the genus Tuba<br />

cluestionably because the aperture and eolnmella are not clearly visible.<br />

It is much larger than 7'. (?) retiel~l(cta Johnson from the IVoodbnry<br />

formation <strong>of</strong> <strong>New</strong> <strong>Jersey</strong> and lacks the radial sculpture. Nanled from<br />

the Latin fons = well.<br />

APPENDIX C<br />

DISCUSSION<br />

1. <strong>The</strong> most significant part <strong>of</strong> the fauna here described is the ma-<br />

terial obtained from Core 16 between the depths <strong>of</strong> 1648 and 1658 feet<br />

(near Harrisville, Burlington County, <strong>New</strong> <strong>Jersey</strong>). <strong>The</strong> <strong>fossils</strong> are<br />

believed to come from the Raritan formation (basal Upper <strong>Cretaceous</strong>)<br />

and to be closely related to the fauna <strong>of</strong> the Woodbine formation <strong>of</strong><br />

Texas as recently described by Stephenson (1952 = 1953).<br />

2. A core from Boring 17 at a depth <strong>of</strong> 1710 feet consists <strong>of</strong> massive<br />

fossiliferous limestone quite unlike anything reported from the Raritan<br />

formation. Horvever, judging by its fauna and by its position in the<br />

section, it is clearly part <strong>of</strong> the Raritan formation. (Plate 94, Figure 9).<br />
