NEW OR OTHERWISE INTERESTING TERTIARY
MOLLUSCAN SPECIES FROM THE EAST COAST
OF AMERICA aes
BY
KATHERINE VAN WINKLE
AND
G. D. HARRIS
INTRODUCTION
In resuming an intensive study of the east American Ter- |
tiary molluscan fauna after an interval of about twenty years,
devoted of necessity to other phases of investigation, the senior |
author finds that there has accumulated in our laboratory several
little lots of fossils, odds and ends, so to speak, that will scarcely
fit into the general systematic studies here being undertaken, for
some time to come. But a knowledge of these fossils and their
occurrence may not be without interest now to Tertiary geolo-
gists and paleontologists in that they may give suggestions as to
where to look and what to look for in various out-of-the-way
places.
The junior author has endeavored to clear up some of the
obscure points in the molluscan faunas of the Eocene of Virginia
and Trinidad, while the the senior author is responsible for what
is said regarding those from the Carolinas and Texas.

REMARKS ON VIRGINIA EOCENE FOSSILS
By KATHERINE VAN WINKLE
The following notes and descriptions are based on material
collected by members of the first cruise of the IANTHINA in Vir-
ginian waters in 1897. Most material, then new, has been sub-
sequently described by members of the Maryland Geological Sur-
vey ; and interesting geographic data on the Virginian beds have
been published by members of the Survey of that State. How-
ever, these few additional notes seem worthy of publication.
Genus LEDA Schumacher
Leda ceelatella, n. sp. Plt Figs. 4,5
Specific characterization.—Size and general form as indicated
by the figures and explanations; rather thick; of the cv/ata
stock, but differing from the Claiborne form by its smaller size,
less inflation medially, less relative contraction posteriorly and
especially by its more primitive surface marking—great diagonal
rugze of nearly equal strength across the whole valve with only
a down-dipping in the young stage as they approach the umbonal
ridge, whereas in cv/ata these rugee are strong only on the sector
just posterior to the middle; in advance of the same such mark-
ings become fainter, swing upward across the channel from beak
to anterio-basal margin and finally resume their former direction
till they reach the margin of the shell; lunule, escutcheon artd
post-umbonal markings very similar to those of célata, though
the radial ribs are more generally and coarsely granulate, thus
recalling cevlatozdes.

Genus CORBULA Bruguiére
Anapteris, new subgenus
Description.—\,esser or left, only valve known ; large, flat,
surface of shell strongly corrugated, this corrugation extends
to the anterior margin where the extreme, anterior portion of the
valve appears as though it had been broken ; on the interior of
the shell this area corresponds to a wing or flare which is bounded
below by a strong ridge; this ridge suggests the original margin
of the valve. The wing bears very fine, radiating striz.
Anapteris regalis, n. Sp., / WO Ts LENS Tha
Description.—Size and shape of shell as indicated by the fig-
ures. Left valve nearly flat, thick, dorsal margin bent out-
ward, giving intimation ofa gape; a pronounced carina extends
from the beak to the posterior margin. Surface ornamented with
prominent, concentric lines which extend from the umbonal
ridge to the anterior end where they terminate in a_ peculiar
manner as though the anterior end had been broken; on the
posterior portion of the shell anterior to the umbonal ridge where
the lines merge into the ridge a separation of the lines occurs
giving place to very short, equally prominent, surface markings.
Just anterior and parallel tothe umbonal carina is a fine channel.
the prominent lines posterior to the umbonal ridge extend almost
vertically to the dorsal margin. On some specimens two slight
channels are noted which are situated between the dorsal margin
and the posterior ridge and extend from the beak to the poster-
ior margin ; on the anterior internal surface of the left valve a
raised margin-like ridge extends from the beak concavely,
and then rounds into the ventral margin ; the portion of the-shell
dorsal to the ridge has the appearance of a flare or wing. The
projecting, cartilage process in the left valvein this form differs
from that in the genus Coréu/a, in having only a very narrow,
short, posterior groove; the anterior groove is slightly marked,
in some cases practically obsolete.

Cenus FICUS Klein
Ficus affinis, n. sp., Plt Big. 10, a:
Description.—Size and shape of shell as indicated by the fig-
ures ; whorls five ; last two whorls of spire smooth ; whorls very
convex ; surface ornamented by numerous, subequally spaced,
longitudinal ribs ; the intersection of the ribs gives the surface of
the shell a cancellated appearance ; both the longitudinal and re-
voling lines extend over the full length of the body whorl and
the first two whorls of the spire.
This form resembles in general outline the species /7czs
mississsippensis (Conrad) from Vicksburg but differs in the
greater regularity of the revoling ribs, in the smaller interspaces
between the revoling ribs and in the absence of finer, intervening,
revoling lines which are characteristic of /. mzssissippensis.
These lines vary in the young and adult stages of the Vicksburg
form, from one totwo in number. A single, partially developed,
intervening line is noted on a specimen of /. affinis. ‘The gener-
al resemblance of the two species seems to indicate /. afinis as
the ancestor of /. we/ssissippensis.

surface smooth except for fine lines of growth. | Body whorl dis-
coidal, ornamented with three very strong, equally distant carine ;
aperture subovate, posterior margin straight ; umbilicus moder-
ately large, surface decorated with fine, regularly, revoling strie;
base convex, smooth; at about the middle of the volution of the
bedy whorl the basal carina divides, gradually producing two
ribs or ridges of equal size with a slight interspace ; they appear
to merge into the aperture as one carina, but examination under
the microscope shows the dual character.

extend continuously over the margin and probably over most of
the surface of the base.

A FEW MID-UPPER EOCENE FOSSILS FROM THE
CAROLINAS AND TEXAS.
BY
G. D. HARRIS
The following specimens from isolated localities whose geol-
ogic horizons are for the most part not very definitely established
seem worthy of description and illustration.
Venericardia eutawcolens, PO: oO cee
Specific characterization.—Size and general form as indicated
by the figures and explanations; rather inflated ; substance of
the shell rather thin, showing on molds of the interior the posi-
tion of the ribbing ; ribs about 28-30 in number, compound, tri-
partite, the middle part strongest, highest and most crenulate or
Spinose ; interspaces from % to % the width of the compound
ribs ; ribs about the umbonal region simple, finely crenulate, dis-
tinctly so just in front of the lunule which is small, deeply sunken.
The ornamentation, or ribbing of this form differs materially
from that of any other species of the genus with which we are ac-
quainted. Inthe usual a/¢zcostata type of ribbing there is a central
keel superimposed upon a broader foundation, giving a terraced
structure on each side. Here there are actually three raised,
radiating, nodose, strong riblets upon each rib, the center one
being somewhat the strongest, however. This reminds one of
the exterior markings on some Pectens.
The ribs in Conrad’s lV’. blandingz are of the very carinate
‘‘wilcoxensts’’ type and not of the trilinear style of our new form.
The ‘‘side-ribs’’ in perantigua as figured by Whitfield in Mon. U.
14 BULLETIN 33 14
S. G. S., No. 9, pl. 30 lack the prominence of those in the South
Carolina form and are not nodose while the interspaces are as
wide as the ribs.
Type—C. U. Museu:
Locality.—Eutaw Springs and Centre Hill, S. C. ; specimens
are casts ina hard creamy-white limestone.
Metis ? eutawensis, n. sp., Pika Rica
Characterization. —A quadrangular cast of the interior of a
Tellinoid shell measuring 45x37x8 mm., showing no signs of lat-
eral teeth, with but faint indication ora posterior flexure, but
with traces of a profound pallial sinus ; interiorly with low ridges
radiating before and behind the anterior muscular scar, accurately
delimiting the same, while the posterior muscular scar is not
sharply defined; post-umbonal slope clearly defined but not
marked off by a sharply carinated ridge.
Type.—Paleont. Museum, Cornell Univ.
Locality.—Eutaw Springs, 5S. C. Expedition of 98.
Crassatellites eutawcolens, n. sp., JPM Ds ee
Characterization.—Internal cast of a medium sized (39x30x
to mm), sharply angular and elevated form, quite different from
any known Eocene Crassatellites above the basal beds of the Gulf
States ; marginal crenulation fine on the posterior, very coarse
postero-basally and disappearing anteriorly ; basal margin rather
full or sub-angular medially ; umbonal ridge sharply defined ; ex-
terior apparently with well-defined, even, concentric lirations.
7ype.—Paleont. Museum, Cornell Univ.
Locality.—Eutaw Springs. Cornell Expedition of ’98.
Meiocardia carolina, n. sp., Pll 2 ie seaseaoe
Characterization.—Size and general appearance as indicated
by the figures; inflated, with a well-defined post-umbonal slope,
on which, about two-fifths way from the ridge to the ligamental
margin there is a well-defined radiating ridge ; traces of interior
radiating lines sometimes present; marginal impressions indi-
cating a fairly thick shell; concentric undulations noticeable
I5 AMERICAN TERTIARY SHELLS 15
basally and posteriorly.
Small casts of these species are common at Wilmington and
Eutaw Springs. Sometimes at the former locality specimens the
size of fig. 5 arefound. An impression of the exterior of what
appears to be the same species is in our collections, labelled Neuse
River, 16-17 miles above Newbern, N. C. This shows, besides
rather regular concentric undulations posteriorly, fine concentric
lining. These lines are almost rectilinear medially but curve up
rather abruptly anteriorly and posteriorly. | This reminds one of
Dall’s 1/7. agassizi, a recent West Indian species.
Types.—Paleont. Museum, Cornell Univ.
Localities.—Eutaw Springs, S.C. ; Wilmington, N. C., and
Neuse River above Newbern.
Pecten trentensis, n. sp., ILD, ies. Sh, Gi:
Specific charactertzation.—Form and size as indicated by the
illustrations ; ribs highly variable in number, size and amount of
ornamentation ; generally bifid and generally ornamented by
highly raised, scale-like or imbricating concentric lines ; costation
showing a strong tendency towards a tri-or quinque-costate pat-
tern, especially in the left valve ; central rib largest of the three
or five major ones.
The general appearance of this shell is so different from any-
thing we have heretofore found in the Eocene of this part of the
United States that, owing toa lack of well-known species from
the same locality, its horizon must at present be considered as
doubtful.
Type and specimens figured.—Deposited by G. D. Harris in
Museum at Cornell Univ.
Locality.—Found in light, marly bed, right bank of Trent
river, near the water’s edge, about six miles below Polloksville,
North Carolina, in the so-called Trent formation, The latter
has been referred to the upper Claiborne or Jackson Eocene.
Pecten elixatus Con. ? IBA, Ieee. Wey Tite
A few fragments of another species of Pecfen were found
16 BULLETIN 33 16
among the. representatives of the species just described, which
seem at first sight to belong to P. fouwlson?. But upon direct
comparison of the two the left valve of pow/sonz is never flat and
in some instances decidedly gibbous, whereas in this species the
fragment figured indicated a plane, or even concave valve.
Again, the ribs on the posterior ear are much more numerous in
this North Carolina species and the posterior cardinal angle less
than 90°. The tops of the ribs in fowlsonz appear broad and
tri-partite ; in this species, bi-partite. The concentric sculptur-
ing is much the same in both species. However, a large series of
these forms may cause them to be finally regarded as one species.
If so, it would seem that a considerably greater geologic range
should be given to this species than has been admitted heretofore
else the horizon on the Trent whence these specimens came is far
higher than has been suspected. A rather near relative of powl-
sonz has been described by Dall as Burnszz from the Chipola marls
of Florida: (iraus. Wag. Tl, 1898) p. 720) sole eaeesommsns)
Conrad’s elzxafus from ‘‘near Santee Canal, South Carolina, in
white, friable limestone’’ is generally referred to poulsonz Mort.
Pecchiolia dalliana, n. sp., PR incom a
Specific characterization.—-Size and general appearance as in-
dicated by the figure ; extremely inflated and generally Exogy-
roid surface marked by numerous radiating small ribs becoming
stronger and farther apart as the position of the umbonal ridge
is approached ; there occasional inter-riblets appear ; passing the
umbonal ridge the strength of the ribs decreases to the ligamental
nlargin ; a radiating channel divides the post-umbonal into two
nearly equal portions ; concentric markings consist of numerous
rather irregular and ill-defined undulations, strongest basally.
This shell is strikingly similar to P. wemmelensis Vincent from
the ‘‘Sadles de Wemmel’’ (Bull. Soc. royal Mal. de Belg. vol. 32,
1897, p. Xxx) and, since these sands are the equivalent of the
Barton Beds of England one instinctively thinks of the aid, small
though it may be, that this form may render usin correlating
the upper Eocene deposits on either side of the Atlantic.
17 AMERICAN TERTIARY SHELLS 17
Our specimen is mainly in form of a cast, from the City Quarry
near Wilmington, N. C., found among many other beautiful
molluscan remains, echinoderms and branchipods.
We take great pleasure in styling this the Dall Pecchzolia not
only on account of the great and valuable Tertiary work of this
author, but especially on account of his early extensive and pains-
taking work on this branch of Pelecypoda.
Type.—Deposited by Harris in Museum at Cornell.
Meretrix angeline n. sp., LD, | TNS. A, Ane
Specific characterization.—Shell large (65x54x15mm) and
oblong, asindicated by the figures ; anterior somewhat extended
as in Cornell: but posterior not with broad circular sweep of con-
centric lines, but with more or less of a rectilinear truncation ; pal-
lial sinus small, V-shaped ; anterior muscular scar sharply defined,
posterior scarcely visible ; a few obscure radiating ridges intern-
ally and a few radiating lines.
This large species, (figures somewhat less than life size, ) is
found in the state of casts and impressions in sandy ironstone
fragments gathered by A.C. Veatch along the Angelina River,
Angelina County, Texas, 2 miles above Marion.
It seems very different from anything with which we are ac-
quainted in the lower Eocene beds, and is here associated with an
abundance of Azomza, (also Plicatula filameatosa, Ostiea var. ver-
nulla, Spherella tulla and anteproducta, ) reminding one strongly
of the St. Maurice beds of Louisiana; alsoa small, smooth Pecten ;
but most telling among its associates are Haminea grandis, Pleur-
otoma creno-strinata Heilp., of Jackson age; but one of the most
abundant speciesis Rimella cf. texana, a St. Maurice form. A
Fusoficula and an unusually large Zornatina are among the un-
described associates. (See below. )
7 ypes.— Deposited in the Paleont. Mus., Cornell Univ.
Tornatina angeline, n. sp., Pl. 2. Fig, 14.
Specific characterization.—Form and general appearance as
figured ; shell thin, smooth, marked only by indistinct longitud-
18 BULLETIN 33 aig 18
inal lines of growth which swing forward in the medial portion of
the volution giving the margin of the lip a broad, curved form ;
margin of the lip somewhat in-flected ; spire very short, of scarcely
over two volutions, suture broadly channelled.
Thisis a large, imposing type of Zornatina, measuring in
adult specimens 23mm. in length by 13in diameter. It is found
abundantly in the material above described in association with
Meretrix angeline.
Fusoficula angelinensis, n. sp., Pl: 2yeabneeeise
Specific characterization.—More or less long—Scaphella-
shaped as illustrated ; differing from all other members known to
the writer in its elongate form, with no traces of a shouldering
above on the body whorl and notraces of tri-carination medially ;
revolving lines stronger than the longitudinal, and showing gen-
erally a secondary intermediate lesser series.
Found associeted with the above on Angelina River, Tex.
REMARKS ON SOME NEW SPECIES FROM TRINIDAD
BY
KATHERINE VAN WINKLE
The material from which the following species were obtained
was collected in 1912, on the island of Trinidad by A. C. Veatch
under the auspices of the General Asphalt Company of Phila-
delphia, Miss Carlotta J. Maury being the Paleontologist. The
stratigraphy and paleontology was subsequently worked up by
Dr. Maury and published in the Journal of the Academy of Sci-
ences of Philadelphia. A few forms not reported seem interest-
ing and worthy of description.
Thanks are due to Professor Harris for the use of the mater-
ial from both Virginia and Trinidad and for suggestions in the
determinations.
The descriptions of the localities where these forms were
collected have been taken from the notes of Miss Maury, that
were found with the material.
Genus ASTARTE Sowerby
Astarte mauriana, n. sp., yeas 3y Fig. it
Description.—Size and shape of shell as indicated by the fig-
ures ; inequilateral, beaks situated about one-third the length of
the shell from the anterior end ; a very slight, umbonal ridge ex-
tends from the beaks part way down the posterior end of the shell
causing a faint, noticeable concavity behind ; surface ornamented
with wide, heavy concentric ribs, interspaces half the width of
the ribs. In the situation of the beaks and in general outline
this form varies from a typical As¢arfe and recalls the form of
Pitaria or allied Venerid genera. Longitude of shell 15mm.

Astarte trinidadensis, n. sp., Pl.22 eigewe
Description.—Size and shape of the shell as indicated by the
figures ; subequilateral ; lower portion of the anterior and poster-
ior ends similarly rounded, blunt in outline ; surface decorated
with six prominent, narrow, raised concentric ribs, the inter-
spaces very wide, two or three times the width of the ribs. This
species differs from A. mauriana, n. sp., in the beaks being
more central, in a more rounded posterior end, lower in form and
in the (character and number of the concentric mbss, =iniae
trinidadensis the ribs are more pronounced, much narrower and
fewer in number. ‘There are lessthan twice the number of ribs
in this species than in our other form of Astarfe. Longitude of
shell 15mm ; altitude romm.

terior, ventral margin ; surface ornamented with prominent, con-
centric lamellee which are much more pronounced and heavier
on the anterior and central portion of the valve, decreasing in
size from the posterior umbonal ridge backward. Longitude of

Genus MACROCALLISTA Meek
Macrocallista ? veatchi, n. Sp.. Pl. 3. Figs. 6, 7.
Description.—Size and shape of shell as indicated by the fig-
ures ; high compared with the size of the shell; beaks situated
nearly centrally, swollen ; surface sculpture consists of numerous,
moderate in size, radiating ribs with very narrow interspaces,
less than one-half the width of the ribs. The first cardinal of the
right valve differs from the type of J/acrocallista in being a very
large, heavy tooth, the posterior ligamental groove in this form
is not as deep or external asin most species of Macrocallista.
These characteristics, with the shortness of form probably makes
the species of sectional rank. Longitude of shell 22mm: altitude

whorls five or six ; on the specimen we have, the last volutions of
he spire are broken, but the spire would probably measure half
he length of the body whorl; suture distinct, appressed ; a ser-
-ies of large, sharply rounded nodes occur on the upper portion of

the anterior end ; upper volutions similarly decorated with nodes
which begin at the sutural line and become obscure just above
the central portion of the whorls; surface of the shell smooth ;
below the nodulation of the body whorl, with the aid of the mi-
croscope, very fine revoling strize may be detected.

Genus PSEUDOLIVA Swainson ,
Pseudoliva soldadoensis, n. sp., Pl 3.) bigesios
Description.—Size and shape of shell as indicated by the fig-
ures ; whorl, six, convex, with a slight shoulder ; last three volu-
tions of the spire, narrow and very pointed ; the shoulder of the
body whorl extends at about an angle of thirty degrees and
bears numerous small nodes. Much of the surface of the body
whorl of our specimen has been destroyed but on the remaining
portion which is about a third of the whole whorl there are
twelve nodes ; on the whorls of the spire a groove extends irreg-
ularly around the shoulder ; traces of nodes can beseen along the
front of this groove. The surface of the shell is otherwise
smooth except for lines of growth. This species is related to
Pseudoliva sp. that Professor Harris has figured from the Midway
of Alabama, pl. 9, fig. 22, Bulletins of American Paleontology,
vol. 1, no. 4. They both have the small nodes on the shoulder
of the body whorl and the upper portion of the spire, similarly
shaped. P. soldadoensis n. sp. is a more robust form, the upper
portions of the whorls are more convex and the nodes are more
numerous. Altitude of the shell 33mm ; diameter 20mm; _alti-
tude of spire 7mm ; angle of spire 83.

Gyprea vaughani Maury, Jour. Acad. Nat. Sci, Fhila., 2nd ser. vol.
REV OKA ps OT. ple XT he. 145. 15.
Original description.—‘‘Shell small; pyriform, tapering to a pointed
base ; inflated ; surface smooth except for faint lines of growth, which are
most apparent on the earlier whorls; spire distinct, acute, showing two
small volutions, with a clearly defined suture; aperture rather wide, but so
filled with the indurated matrix that all plications are concealed ; outer lip
much thickened, inner lip with a rather fine callus.
Height of shell 24, greatest width 17, thickness 14 mm.
_ Remarks: This particular Cyprea is wholly unlike anything described
jrom the-lower Eocene horizons.”’
We have been able to obtain, since Miss Maury described
this species, three additional specimens and remove the rock ma-
trix so as to reveal the character of the aperture, the smooth col-
umella and crenulated outer lip.
Size and shape of shell as indicated by the figures ; whorls
five; a deep posterior sulcus, the margin of the outer, if height-
ened or extending over the whorls of the spire as in many young
Cypree; the very characteristic feature of this species is the
elongate, Pyrula-like base or canal.

PLEUROPHOPSIS, new genus
Description.—The form known only from casts ; large, elong-
ate, inequilateral, beaks situated about one-fourth the length of
the shell from the anterior end; surface sculpture cotisists of
heavy, concentric lines of growth ; two cardinal teeth in the left
valve, the posterior cardinal very large, the anterior slender ;
24 BULLETIN 33 24
right valve bears two cardinals of subequal size ; anterior adduct-
or impression very large and high with a wide, deep groove be-
hind, which would correspond on the shell to a deep adductor
scar and ridge between it and the umbonal area ; pedal muscle
scar conspicuous and situated dorsal to the adductor, posterior
muscle impression and pallial line very indistinct, no sinus notice-
able.
From the dental and muscular structure this form seems to
be a descendant of the Pre-Tertiary genus Pleurophorus.

Unio sp. Maury, Jour. Acad. Nat. Sci. Phila., 2nd ser. vol. XV, 1912,
p. 50, pl. VIII, figs. 18, ro.
Description.—Size and shape as indicated by the figures and
explanations; slight umbonal ridge extends from the beaks and
merges into the posterior ventral margin ; surface sculpture con-
sists of rather heavy, concentric lines of growth. Longitude of
shell 77 mm ; altitude 33 mm.
Remarks.—This and the following new species from the saine
locality represent a large collection of casts, the hinge structure
of which, for the most part, are but poorly preserved. The
fauna is very peculiar and unlike any known. Because of its
uniqueness and questionable origin it was thought that the forms
should be figured and described as far as possible, thus placing on
record the occurrence of such a fauna.
The species just described, in outline and in the occurrence of
the heavy muscular impression, resesembles a Unzo. But the
presence of clear cut dentition eliminates that genus. We have
also in the collection a species of Leda, Nucula and Modiolaria as
well as a number of marine gastropoda.

Pleurophopsis unioides var. fernandensis, n. sp., Pl. 3. Fig.13, 14.
Description.—Size and shape as indicated by the figures ;
umbonal ridge which extends nearly to the posterior, ventral mar-
gin well marked in the young ; two very wide, deep furrows ex-
tend on the anterior portion of the shell from the area of the beak
to the ventral margin ; the groove most anterior extends prac-
tically straight to the basal margin, while the second groove ex-
tends obliquely toward the posterior end of the shell ; where this
furrow inerges into the base, the margin of theshell forms on in-
dentation, from here the anterior portion is drawn out at about
an angle of 30 degrees to the dorsal margin ; this gives the form
on aviculoid appearance, this extreme contortion is characteristic
of the large, adult specimens, the young show the two anterior
furrows but are more moderate in form, showing the shape of the
parent species, P. unzozdes ; surface sculpture consists of heavy
lines of growth which in the adult become very rugose along the
tmbonal ridge ; longitude of shell 134 mm; altitude 55 mm.

Unio sp. Maury, Jour. Acad. Nat. Sci. Phila., 2nd ser. vol. XV, 1912,
p. 50, pl. IX, fig. 1.
Description.—Shell attaining a very great size; shape as in-
dicated by the fignres, in the young form the shape is more quad-
rate, the posterior end less attenuated ; in the young and inter-
mediate stages a very characteristic, strong fold or flexure extends
from the beaks to the posterior margin ; this groove which is
so marked in the early and medium stages is greatly reduced in
26 BULLETIN 33 26
the adult.
Our collection of this species consists of a series of four spec-
imens, which range in length, 22 mm, 87mm, 118 mmand123mm
respectively ; were it not for this series showing the gradation in
size and umbonal ridge one would not be inclined to identify the
two extremes as the same species.
This form resemble 7hyastva bisecta (Conrad) from the Mio-
cene of the West Coast of North America. The Pacific species,
however, does not reach such a ponderous size. No species of
this genus has been reported from the East Coast American Ter-
tiaries. This would seem to give our fauna a closer affinity with
the West Coast forms of the Middle Tertiary Stages.
Types.—Pal. Museum, Cornell Univ.
Age.—Probably Middle Tertiary.
Locality.—*‘One mile west of Godineau River, on the shore

SOLARIELLA S. Wood
Solariella godineauensis, n. sp., : Pl, 27 Eos wanige mice
Descriptiou. —Size and shape of shell as indicated by the fig-
ures ; body whorl ornamented with three, pronounced, equally
distant carinz ; all of the whorls are carinated but with each suc-
ceeding volution the carination is diminished by one ; as the car-
inze extend to the apex they become more and more crenulated ;
in the concave area between the shoulder and the suture is a
smaller keel very strongly crenulated, producing a nodose condi-
tion; these are caused by the intersection of the keels with
prominent, radiating ribs which extend from the suture to the
shoulder carina, traces of these ribs may be seen on the lower
portion of the body whorl; they have interspaces of about three
times the width of a rib; aperture wide and flaring, this flare ex-
tending conspicuously out from the basal margin; two or three
additional revoling ridges extend on the body whorl below the

RECENT MOLLUSCS OF THE GULF OF MEXICO AND
PLEISTOCENE AND PLIOCENE SPECIES FROM
THE GULF STATES
BY
CARLOTTA JOAQUINA MAURY
INTRODUCTION
While acting as paleontologist on the Louisiana State Geo-
logical Survey, some years ago, a great number of deep well fos-
sils were placed in my hands for identification by the Director of
the Survey, Professor G. D. Harris.
Many of the well fossils had been collected in the Jennings
oil field which was then being actively exploited, and an interest-
ing series was presented to the Survey by Mr. Knapp from his
experimental wells in Terrebonne Parish. Mr. Krackie of New
Orleans also presented a collection from the Gymnasium Club
well in that city. Specimens from Alabama wells were loaned by
Mr. Aldrich.
Professor Harris made extensive collections of recent shells
at points along the coast from Cedar Keys, Florida, to Galveston,
Texas, and he and Mr. Whitney collected a large number of
Pleistocene shells at Grand Chénier, Louisiana, and at the New
Orleans pumping station. These recent and Pleistocene shells
were also identified by the writer and used for comparative study
with the well fossils.
It is rather singular that while the molluscan faunas of our
Atlantic and Pacific coasts have been extensively studied, the
Gulf Coast fauna has been comparatively neglected. For this
reason it seems as though an annotated catalogue, embracing the
results of our work, and that of Dr. Dali, Messrs. Hilgard, Sing-
ey, Aldrich, Mitchell, Vanatta and others, might be of value.
4 BULLETIN 34 36
The field covered by the following catalogue includes the
recent littoral species from Tampa, western Florida, to Galves-
ton and Corpus Christi, Texas; the recent deep water and abys-
sal species dredged by the Steamer Blake in the Gulf of Mexico,
south to the Straits of Florida and the Channel of Yucatan; the
Pleistocene, Pliocene, and a few Miocene species from Gulf State
wells; the Pleistocene species of Grand Chénier; the marine Pli-
ocene species of North Creek, western Florida, and the curious
brackish water Pliocene species of Alexandria, Louisiana, and of
Burkeville, Texas, which are closely related to those of the Sa-
tilla River, Georgia.

Remarks.—This species, which is ancient and widely distrib-
uted, varies greatly in concentric sculpture. Conrad, in
the original description, speaks of the concentric strize as
prominent and Dall states that in some instances they may
even become coarse ribs or waves. Other forms are near-
ly smooth. ‘This is generally so with our material from
the Gulf border.

coast, and is the commonest Avca in the adjacent wells.
The specimens from the wells are often extremely small,
young forms. A Miocene variety, dusana Harris, was
found in the Galveston well in 1895, It is more elongated
and less inflated than the typical form of this species.

Shell very small, suborbicular, with nearly central, rather
prominent, acute beaks. Lunule deep, lanceolate ; radial
sculpture of fine but well-marked, rounded riblets, slight-
ly unequal, not divaricating. and alternating with narrow-
er interspaces. Riblets absent from the dorsal area. Con-
centric sculpture of narrow, slightly raised lamellz, which
cross the broader riblets. The lamellae become stronger
over the dorsal area where the riblets are absent. Hinge
heavy in proportion to the shell. Right valve with a
strong posterior, and a weaker anterior lateral tooth, and
one rather prominent cardinal tooth. Inner margin of
shell crenulate. Length and height 4mm., semidiameter
I.5 mm. This species resembles closely Phacoides approx-
imatus Dall, dredged in the Gulf of California at 26 fms.
The two species would seem to have been undoubtedly de-
rived from a common ancestor.

a doubtful horizon where, though recent forms largely
prevail, a slight change in the fauna appears. This leads
one to think that one may be approaching the Upper Mio-

Note.—The type locality of Conrad’s V. Jdatilirata was the
Miocene of Calvert Cliffs, Maryland. Conrad laid stress
upon the irregularity of the ribs (one being usually very
wide), of the Miocene specimens, and we have noticed
this peculiarity strongly in specimens from great depths in
the deep wells. It cannot, however, be taken as an invari-
able characteristic, for the regularly ribbed type, which is
rather more characteristic of the Recent, occurs also in
the Miocene.
