INTRODUCTION

This paper is the seventh part of a work the intent of which is to
describe and illustrate the Foraminifera of the Atlantic Ocean,
especially those species which have occurred in the waters adjacent
to the shores of the United States, including the whole of the Gulf
of Mexico and the Caribbean Sea, that being the area in which most
of the work of the vessels of the United States engaged in dredging
work has been done. This part includes the families Nonionidae,
Camerinidae, Peneroplidae, and Alveolinellidae. Many of the species
of these families live in warm, shallow waters and are not abundant
in the deeper waters dredged by the United States Bureau of Fisheries
steamer Albatross. Some of the Nonionidae, however, are very
abundant in these dredgings.

THE FORAMINIFERA OF THE ATLANTIC OCEAN

NONIONIDAE, CAMERINIDAE, PENEROPLIDAE, AND
ALVEOLINELLIDAE

By JosePpH AUGUSTINE CUSHMAN
Of Sharon, Massachusetts

INTRODUCTION

This seventh part of the work on the Atlantic Foraminifera deals
with the Nonionidae, Camerinidae, Peneroplidae, and Alveolinellidae.
The Nonionidae are represented in the Atlantic by but three genera.
These are represented by numerous species, however, often very
abundant in dredgings and in shoal-water samples. The Camerinidae
are almost wanting in the Atlantic, but are abundant in the Indo-
Pacific. The Peneroplidae and Alveolinellidae are represented by
simpler, more primitive species in the Atlantic than in the Indo-
Pacific, but a few of the species are very abundant in the West
Indian region.

Family 24. NONIONIDAE

Test typically planispiral, more or less involute; wall calcareous,
finely perforate; aperture simple or cribrate, if simple, at the base
of the apertural face.

This family is most abundantly represented in rather shallow
water. Of the three most abundant genera, Elphidium, Nonion,
and Nonionella, Elphidium reaches a great development in warm,
shallow waters, especially of the Indo-Pacific where the largest
species are found. It is also very abundant along the shores of
cold regions, but the species are usually much smaller. Nonion and
Nonionella are more abundant in a little deeper water as a rule,
but the various species are well adapted to geographic ranges as
are those of Elphidium.

The Palaeozoic genera, Cribrospira and Bradyina, may not belong
in this family, although they have much in common with the other
members. Orbignyna is limited so far as is known to the Cretaceous.
Polystomellina and Faujasina show peculiar modifications, a trochoid
form taking the place of the planispiral in the adult.

The structure in most of the genera is fairly simple, but in the larger

species of Elphidium it becomes complex.

Genoholotype.— Nautilus incrassatus Fichtel and Moll.

Test free, planispiral, more or less involute, bilaterally symmetrical,
periphery broadly rounded to acute; chambers numerous; wall finely
perforate; aperture, an arched, usually narrow opening between the
base of the apertural face and the preceding coil.

Carboniferous (?) to Recent.

Most of the species of Nonion are simple in their structure,
without a canal system, usually with little ornamentation and not
reaching any great size. The passage to Elphidium is a gradual
one and there are some species of the latter which do not develop
the retral processes until toward the end of the growth of the test
and which in their early stages would be classed as Nonion. This
seems to be the most primitive genus of the group.

NONION (?) UMBILICATULUM (Walker and Jacob)
Plate 1, figures 1 a—b

“‘Nautilus spiralis umbilicatus sulcatis’” Wa.LkER and Boys, Test. Min.,
1784, pl. 3, fig. 69.

Nautilus umbilicatulus WALKER and Jacos, Adams’s Essays, Kannmacher’s
ed., 1798, p. 641, pl. 14, fig. 34.

A reproduction of the original figure is given here. There is much
uncertainty regarding this species. As will be seen by the figures,
the two sides are evidently not the same. Parker and Jones com-
mented on this figure as follows: ‘Figure 69 is a common form of
Truncatulina lobatula, having the outline of the cells uniform or
flush; the septal lines being merely ‘furrowed.’ According to Walker,
it was from Sandwich—not common.”

“Montagu, (Test. Brit. Suppl. p. 78), refers to this figure when
describing a little Nonionina; and Williamson (Monogr. p. 42),
makes it a Polystomella. We believe that they must both be wrong,
because in the specimen figured by Walker the two faces are decidedly
unsymmetrical.”

FORAMINIFERA OF THE ATLANTIC OCEAN 3

If the Boys specimens are preserved, it would be a simple matter
to straighten out this tangle, but until such time as this is done
there is much uncertainty as to the species. In this connection
it is enlightening to note Montagu’s comments on the Walker and
Jacob figures (copied from Boys), as he had at that time both the
original specimens and drawings. ‘Indeed we perceive so consid-
erable a difference between the original drawings * * * and.
the engravings taken from them that we would scarce have known
them to be the same, had they not been marked with the same

numbers.”
NONION (?) CRASSULUM (Walker and Jacob)

Plate 1, figures 2 a-b

‘‘Nautilus spiralis crassus utrinque umbilicatus geniculis lineatis’’ WALKER
and Boys, Test. Min., 1784, pl. 3. fig. 70.

Nautilus crassulus WALKER and Jacos, in Adams’s Essays, Kannmacher’s ed.,
1798, p. 641, pl. 14, fig. 35,

This species described from Reculver on the north coast of Kent,
England, has been little referred to and the original figure leaves much
to be desired. If the types are extant, it may be possible to estab-
lish this species on a firm basis. Williamson has referred a form to
it which is evidently not at all the same. The original figure is copied

here.
NONION DEPRESSULUM (Walker and Jacob)

Plate 1, figures 3-6

‘‘Nautilus spiralis utrinque subumbilicatulus’’ WaLKER and Boys, Test.
Min., 1784, p. 19, pl. 3, fig. 68.

Nautilus depressulus WALKER and Jacos, in Adams’s Essays, Kannmacher’s
ed., 1798, p. 641, pl. 14, fig. 33.

Nonionina depressula HERON-ALLEN and Earuanp, Trans. Linn. Soc. Lon-
don, ser. 2, vol. 11, 1916, p. 279, pl. 43, figs. 4-7.

There are a great many records given for this species. It was de-
scribed from Reculver on the north coast of Kent, England. The
type figure which is copied here (pl. 8, fig. 3), shows a form with many
low, elongate, curved chambers with a small, central, umbilical area.
There are very few figures indeed of this species although the number
of references is large. Brady’s Challenger figures do not at all fit this
form, but seem nearer to N. umbilicatulum. Of the figures given,
those of Heron-Allen and Earland quoted above and copied here,
(pl. 8, fig. 4) seem to come the nearest to the originals, but these have
fewer and broader chambers. Such forms are certainly abundant
about the British Isles and the adjacent coast of Europe, and it seems
that the name should be restricted to this form. The periphery is
rounded, the sides slightly concave, sutures slightly limbate and

much curved, chambers about 10 in number which is several fewer
than in the type figure.

NONION POMPILIOIDES (Fichtel and Moll)

figs. 10-12, Modéles No. 86.

Nonionina melo p’OrBiGNy, Ann. Sci. Nat., vol. 7, 1826, p. 293.

Test planispiral, bilaterally symmetrical, entirely involute, except
that the umbilici are deeply excavated, periphery very broadly
rounded, entire; chambers 8 to 10 in the last-formed coil, of the same
general shape, not inflated; sutures flush with the surface, generally
limbate, fusing along the umbilicus to form a slight thickening about
it but not raised above the surface; wall smooth, coarsely perforate;
aperture slit-like between the base of the apertural face and the previ-
ous coil, apertural face broad and low.

This species described by Fichtel and Moll from Recent specimens
from the Mediterranean and Pliocene ones from Coroncina, Italy,
has been widely recorded. It isnot common, however, in the Western
Atlantic, but does occur typically, especially in the Late Tertiary of
Italy. Joseph Wright recorded a specimen from southwest of Ireland,
1,020 fathoms,' and Heron-Allen and Earland a single specimen from
the Clare Island region of Ireland.?

It occurs sparingly in deep water material. Brady records it in the
Challenger material from seven stations in the North Atlantic ranging
from 1,000 to 2,750 fathoms, and one in the South Atlantic 2,200
fathoms.

The species is similar to N. umbilicatulum (Walker and Jacob) butis
a much broader, more globular form and the umbilicus is not usually
so open.

It is probable that Nonionina soldanii d’Orbigny from the Vienna
Basin Miocene belongs here also.

depressed, not limbate; wall smooth, finely perforate; aperture, a
small opening at the base of the apertural face next to the preceding
coil.

Both Nautilus scapha and N. faba of Fichtel and Moll seem to
represent the same species, and d’Orbigny’s Nonionina communis
from the Vienna Basin is apparently the same from material exam-
ined.

There are a great many records for Nonion .scapha in the literature,
but as very few of them are accompanied by illustrations, they can
not be definitely placed here until the material representing them can
be examined and checked.

As already noted, there is a tendency toward N. asterizans especially
in the Italian region.

Test planispiral, bilaterally symmetrical, completely involute or
very slightly evolute, periphery angular, umbilici depressed, often
with a few very small beads; chambers numerous, usually about 12
in the last-formed coil, broad and low, of uniform shape throughout;
sutures distinct, depressed, usually somewhat limbate, the broadest
part toward the inner end thence thinning toward the periphery,
evenly curved; wall smooth, except for the umbilical region which
occasionally has a few small beads, finely perforate; apertural face
convex, in peripheral view with the sides convex, aperture itself at
the base of the face next to the previous coil, short and narrow or
sometimes rounded.

The originals of Fichtel and Moll came from the Mediterranean.
The species is common in the Pliocene of Italy and in the Pliocene and
Miocene of many parts of Europe. Many species have been placed
under this name that obviously do not belong here. d’Orbigny’s
Nonionina boueana from the Vienna Basin Miocene does not differ
essentially from Fichtel and Moll’s species. In fact, the figure
given by Fornasini from the ‘‘planches inédites’”’ has the umbilical
region slightly beaded.

FORAMINIFERA OF THE ATLANTIC OCEAN 7

There seems to be no authentic record of the species from the West-
ern Atlantic and it apparently has a Mediterranean and Indo-Pacific
distribution at the present time. A few specimens are referred to
N. boueana from the Coast of England by Heron-Allen and Earland.
Goés records it in his paper from 48° N. latitude and 10° W. longitude.

Nonion scaphum (Fichtel and Moll) is very close to this species, and
in the Pliocene of Italy the two seem to merge one into the other.
“ Nautilus faba’’ Fichtel and Moll is also close to this species. It is
also from Rimini on the Adriatic and from the Pliocene of the Siena
region.

8 BULLETIN 104, UNITED STATES NATIONAL MUSEUM

D’Orbigny described this species from the Canaries. It is widely
distributed in cold waters. Someofthe Atlantic records areas follows:
Shetland Islands (80 fathoms, very rare); off Nova Zembla, Franz-
Joseph Land and Spitzbergen, Smith Sound, as far north as latitude
82° 33’ N.; off the British Isles, 64-155 fathoms and sparingly on the
British and French coasts (Brady); off coast of Dublin (Balkwill and
Wright); Liverpool Bay (Siddall); Jersey (Halkyard); off South-
port, England (Chaster); off Southwest Ireland and shore sands of
Dogs Bay, Ireland (Wright); Harlem River, N. Y. (Woodward);
Spitzbergen and coast of Norway (Goés); Bognor, Sussex, England
(Earland); Norway and between Norway and Greenland (Kiaer);
off Galway (Millett); Clare Island region, Ireland and west of Scot-
land (Heron-Allen and Earland); Hudson Bay (Cushman).

In the Pleistocene of Ireland (Wright), and near Portland, Me.
(Morton), it appears. There are other fossil records not so well
defined, and a few records for its occurrence in the Mediterranean
and the Pacific but specimens are not typical.

There is a Pacific form similar to that figured by Brady (pl. 109,
fig. 5), which has fewer, higher and more inflated chambers. The
specimens figured by Heron-Allen and Earland from west of Scot-
land are composed of fewer chambers than in the typical form.

A few of the records of N. asterizans (Fichtel and Moll) may be
N. stelligerum, but the originals must be seen to determine this.

region which is filled; wall smooth, distinctly but finely perforate;
aperture, a narrow slit at the base of the apertural face.
_ Diameter usually less than 0.50 mm.; thickness about 0.18 mm.

This is a very common species in the North Sea and about the
British Isles, well figured by Williamson. It is somewhat difficult
to place earlier records without figures, but this has probably been
recorded from this area. It is very close to the species of Elphidium
from the same area such as is referred to by Heron-Allen and Earland
in their report from the west of Scotland as ‘“‘Polystomella faba.”
It is apparently not found on the western side of the Atlantic.

This may be a form of N. scaphum (Fichtel and Moll). It differs
from JN. gratelowpi in the broader apertural face and the narrower
form in front view. d’Orbigny described and figured this species
from Jamaica as rare, and mentioned that it was like a similar form
occurring fossil at Dax. I had material referred to this species from
Late Tertiary marl, from the gorge of the Yumuri River, Matanzas,
Cuba and from Bluff 2, Cercado de Mao, Santo Domingo. It also
occurred in recent collections from San Juan Harbor, Porto Rico.
It may prove to be only a more inflated, but narrower form of
N. grateloupi (d’Orbigny).
Very close to this is the species described by d’Orbigny from shore
sands of Cuba and Jamaica as Nonionina brown. It is a somewhat
inflated form and probably is a synonym of NW. sloaniv.

Test planispiral, bilaterally symmetrical, mostly involute, in
peripheral view the sides nearly parallel, periphery rounded; chambers
numerous, usually 10 to 12 in the last-formed coil in adults, chambers
increasing rapidly in length, especially in the last few chambers;
sutures distinct, slightly depressed; wall smooth, finely perforate;
aperture small, at the base of the last-formed chamber, narrow.

Length, up to 0.60 mm.; breadth, 0.35 mm.; thickness, 0.22 mm.

D’Orbigny originally noted this species from the Miocene of Dax,
France. Later he described and figured a species under the same
name from shore sands of Cuba, Jamaica and Martinique. I have
recorded it from Montego Bay, on the north coast of Jamaica, from
numerous stations about the Tortugas, and from San Juan Harbor,
Porto Rico. It occurred fossil in the Late Tertiary of the gorge of
the Yumuri River, Matanzas, Cuba, and from Bluff 3, Cercado de
Mao, Santo Domingo. It is the most common species of the genus
in the West Indian region.

Plate 4, figure 5

Nonionina barleeana Wiuu1aAMsoNn, Rec. Foram. Gt. Britain, 1858, p. 32, pl. 3,
figs. 68, 69.

Test planispiral, bilaterally symmetrical, much compressed; pe-
riphery rounded, umbilici depressed and open; chambers numerous,
12 or more in the last-formed coil, of rather uniform shape and size;
sutures curved, slightly limbate, not depressed; wall smooth, coarsely
perforate; aperture semicircular, at the base of the apertural face.

Diameter slightly less than 0.65 mm.; thickness, 0.18 mm.

Williamson’s specimens were from Skye, Stornoway, Shetlands,
and Scarborough. Such forms have been recorded from about the
British Isles as Nonionina umbilicatula. With the great uncertainty
existing in regard to the latter species, it seems best to use Williamson’s
name for this cold-water species.

bate; wall thin, finely perforate; aperture, a narrow slit at the base
of the apertural face.

Length, 0.50 mm.; breadth, 0.30 mm.; thickness, 0.30 mm.

This is an abundant species in the cold waters from northern New
England northward, and occurs also off the western coast of America.
Dawson’s specimens were from the Gulf of St. Lawrence.

The apertural face is very broadly triangular.

Test planispiral, ‘bilaterally symmetrical, completely involute,
periphery very broadly rounded; chambers 10 to 12 in the last-
formed coil, distinct, not inflated, of uniform shape; sutures distinct,
slightly depressed, slightly limbate toward the proximal end; wall
very finely perforate, smooth; aperture, a long, very narrow slit at
the base of the apertural face, sometimes divided into several openings.

Diameter, 0.75 mm.; thickness, 0.50 mm.

This species described from the Arctic off Nova Zembla has occurred
typically in Hudson Bay, and is recorded by Heron-Allen and Ear-
land off the west coast of Scotland. Brady in the Challenger Report
gives the following localities: West coast of Nova Zembla, 55 fathoms;
shores of Spitzbergen, 7 fathoms; Faroe Channel, 632 fathoms;
west coast of Scotland, 25 fathoms, and off Valentia, 112 fathoms.
He also records it fossil from a Post-Tertiary clay on the coast of
Fifeshire.

The forms recorded from warm waters and referred to this species
are not the same.

Test planispiral, bilaterally symmetrical, involute, periphery
angular; chambers, about nine in the last-formed coil, of uniform
shape and relative size, slightly inflated; sutures distinct, slightly
depressed, limbate toward the proximal end, the umbilicus filled
and confluent with the sutures; wall distinctly perforate, smooth;
aperture, a low opening at the base of the apertural face.

There are numerous records for this species about the British
Isles, the following among them: Off Dublin coast (Balkwill and
Wright); off Jersey (Halkyard); off Southport, England, rare in
shore gatherings and shallow water (Chaster); southwest of Ireland,
53 and 345 fathoms; Dogs Bay, very rare (Wright); Bognor, Sussex,
rare (Harland); Galway, very rare (Millett); Selsey Bill, Sussex;
Clare Island region of Ireland; west of Scotland (Heron—Allen and
Earland). Wright also records it from the Pleistocene of the north
of Ireland.

This is very much like N. germanicum and may be only a slightly
broader form of the same species.

final whorl consisting of about 7 or 8 segments; margin entire; septa

‘‘A form somewhat allied to N. depressula but differing from that
species in its evolute mode of growth, its even sutures and noninflated
segments. ”’

This species was described and figured by the authors from 940
fathoms off the Abrohlos Bank off Brazil. Its position as a Nonion
seems doubtful, but it is included here for the record.

There are several names given by Ehrenberg which it is difficult
to identify and which with our present knowledge can not be definitely
placed.

1872 (1873), pl. 4, fig. 3, from bottom sample from Atlantic Tele-
graph line, 9,600 feet in depth.

Genoholotype.— Nonionella miocenica Cushman.

Test subtrochoid, the dorsal side only partially involute, ventral side
completely so, close coiled; chambers especially in the adult inaequi-
lateral, the ventral side developing a distinct elongate lobe at the
umbilical end, which covers the umbilicus itself; wall calcareous,
finely perforate; aperture at the base of the apertural face of the cham-
ber, low and elongate, extending from the peripheral border toward
the ventral side.

Cretaceous to Recent.

FORAMINIFERA OF THE ATLANTIC OCEAN 15

The subtrochoid forms belonging to this genus are close to Nonion,
and the microspheric form may be very close to it in many species.
In the megalospheric form there is a tendency to adopt the adult
character at an earlier stage, and it is in this form that the trochoid
character usually becomes most marked. The genus is known as far
back as the Lower Cretaceous. Some of the older fossil species are
as trochoid as Recent ones. The genus seems to be most at home in
fairly cool waters and in the temperate zones although there are a few
species in warmer waters.

This is a common species especially in muddy dredgings about the
British Isles. Whether the species identified with this from other
regions are the same remains to be seen. ‘The following records
seem definitely to belong here: Skye, Arran, Shetland, abundant;
Whitehaven, rare (Williamson); off the Dublin coast (Balkwill and
Wright); south of Norway (Terquem and Terquem); Liverpool Bay,
rare (Siddall); southwest of Ireland, 1,000 fathoms, frequent
(Wright); Isle of Jersey (Halkyard); Portree Bay, Scotland, frequent
(Robertson); off Southport, England, rather rare (Chaster); West
Africa (Egger); Scandinavian coast (Goés); Dogs Bay, very rare
(Wright); south coast of Norway from Brevik Fiord to the Bukn
Fiord, 90 to 350 meters, and is found at Svolvaer, Lofoten, 200
meters; Vesteraalseggen, 1,187 meters (Kiaer); off Galway (Millett);
Clare Island region of Ireland at 16 stations; 20 stations west of
Scotland (Heron-Allen and Earland). There are records for it in the
Pleistocene beds of Norway, Scotland, and Ireland.

Brady’s specimens from off the Shetlands (pl. 109, figs. 17, 18)
(according to Nuttall), show an equilateral face, but this is not usual
in specimens I have seen from the eastern North Atlantic. Brady
speaks of it, however, as follows: ‘This chamber is frequently devel-
oped inequilaterally, and in such cases the test assumes a Rotaliform
aspect, which has been an occasional source of confusion and error.”’

This is a very beautiful little species and occurs abundantly in
dredgings sent me by the late Joseph Wright a number of years ago.
Figures of some of these are given on Plate 13.

Special Publ. No. 1, Cushman Lab. Foram. Res., 1928, p. 204.

Genoholotype.—Orbignyna ovata Hagenow.

Test planispiral, involute; chambers distinct, later ones with the
sides continuing back over the umbilical area; wall calcareous, finely
perforate; aperture in the adult, rounded, in the middle of the aper-
tural face.

Cretaceous of Europe and America.

This genus is allied to Nonion and differs largely in the position of
the aperture which in Orbignyna is rounded and in the middle of the
apertural face instead of a slit between the apertural face and the
preceding coil as in Nonion.

Test mostly involute, bilaterally symmetrical, at least in the adult;
aperture, a single opening or series of openings at the base of the
apertural chamber in the middle line with a supplementary series in
a crescentic line near the peripheral margin of the apertural face,
connecting with the exterior after new chambers are added by a row
of pits along the sutural lines.

Carboniferous.

These two genera, Cribrospira and Bradyina, are peculiar in many
ways and may not belong to this family. They are mostly confined
to the Palaeozoic and probably did not live after that period. Their
relationship to such forms as Endothyra is probably close.

Jurassic to Recent.

The retral processes characteristic of this genus are variously
developed. In some primitive species they are hardly developed but
in others they become very highly developed together with the canal
system of the interior of the wall. In the larger tropical species of
the Indo-Pacific the umbilical bosses become very highly developed
with large pores, and the chambers are very numerous. There are a
great many species as might be expected in such a highly developed
genus, and their geographic ranges are well defined.

Test much compressed, periphery subacute, not carinate, margin
entire, even, sides nearly parallel in peripheral view, umbilical re-
gions not umbonate; chambers not inflated, 10 to 12 or more in num-
ber in the last-formed coil; sutures not depressed, marked by the
retral processes which are short and broad, 7 to 8 in number; aper-
ture composed of several rounded openings at the base of the apertural
face.

Diameter, 0.60 mm.; thickness, 0.20 mm.

D’Orbigny’s types were from ‘‘Patagonia, not far from the Rio
Negro and in sands from the Falklands.’ Specimens comparable to
this species as figured and described by d’Orbigny occur in material
collected by Dr. Waldo Schmitt from the coast of South America and
from the the Falklands. Specimens of this same general form from
as far north as the West Indies may also be placed in this species.

The last chamber as mentioned by d’Orbigny and as is usual in
many species of Elphidium is somewhat inflated, due possibly to
reproductive conditions.

20 BULLETIN 104, UNITED STATES NATIONAL MUSEUM

This form is recorded by Kiaer and Awerinzew from the Arctic of
Siberia, Greenland, and off the coast of Norway. I had it from the
Canadian Arctic Expedition.

The form figured by Heron-Allen and Earland from the west of
Scotland as ‘‘Polystomella decipiens Costa”’ is this species. Their
Figure 21 is very close to the figures of incerta from the same general
region. Costa’s species evidently has a granular umbilical region
and is a different species, the original figure showing a somewhat
keeled specimen.

ELPHIDIUM INCERTUM (Williamson), var. CLAVATUM, new variety
Plate 7, figure 10 a, b

Variety differing from the typical in the ornamentation of the
test, the umbilical portions being occupied by several large irregular
bosses, very distinct but not forming a definite umbonate mass, test
usually yellowish-brown in color.

Holotype (Cushman Coll. No. 10400) from Spar Landing, French-
mans Bay, Me.

This variety is common on the coasts of New England and north-
ward. It occurs on the northern coast of Europe as well.

ELPHIDIUM STRIATO-PUNCTATUM (Fichtel and Moll)

There are very many Atlantic records referred to this species.
The types of Fichtel and Moll were from the Arabian Sea, and are
very different from the many forms assigned by later authors to
this species. Some of these forms will be found here under Elphidium
incertum (Williamson), F. excavatum Terquem, etc.

For the type form of Elphidium macellum (Fichtel and Moll) see
Cushman and Leavitt.’

ELPHIDIUM MACELLUM (Fichtel and Moll)

Although this species is recorded from the Atlantic by authors,
the specimens I have seen are not the same as this species as developed
at the type locality in the Mediterranean.

For the type form of Elphidiwm macellum (Fichtel and Moll) see
Cushman and Leavitt.*

ELPHIDIUM CRISPUM (Linnaeus)

Numerous authors have recorded ‘“‘Polystomella crispa”’ from the
eastern coast of the Atlantic. Williamson in 1858 figured specimens
such as occur off the southern coast of England and which are repro-
duced here. These are not the same as the Mediterranean types of
Elphidium crispum, but are more like E. macellum in some of their
characters. The early stages have a series of sharp spines about the
periphery but these are usually reduced and finally wanting in the
adult. In some respects these forms are close to d’Orbigny’s

FORAMINIFERA OF THE ATLANTIC OCEAN 21

*‘Polystomella aculeata”’ from the Vienna Basin. These are left for
a more intensive study of this genus now under way. Nothing of
the sort occurs so far as I have seen in material from the western
side of the Atlantic.

For the type form of Elphidium crispum (Linnaeus) see Cushman
and Leavitt.®

ELPHIDIUM EXCAVATUM (Terquem)

Polystomella umbilicatula WILLIAMSON (not Walker and Jacob), Rec. Foram.
Gt. Britain, 1858, p. 42, pl. 3, fig. 81.

Test of small size for the genus, much compressed, periphery
broadly rounded, margin entire or slightly lobulate, umbilical regions
usually slightly depressed, sometimes with one or more small, rounded
bosses; chambers few, 8 to 10 making up the last-formed coil, slightly
if at all inflated; sutures distinct, very slightly depressed, marked by
the very short, narrow, retral processes with wide openings, between
8 and 10 in number, usually rather even and distinct; wall smooth;
aperture composed of a row of small, rounded pores at the base of
the apertural face.

Diameter, 0.40 mm.; thickness, 0.12 mm.

This species described and figured by Terquem from off the Atlantic
coast of France seems to represent well a common species found on
the coasts of Belgium and about the British Isles. It is somewhat
like E. incertum (Williamson), but is more compressed, has the retral
processes more even and in larger numbers, and the umbilical region
is different. It has passed under the general name of ‘‘ Polystomella
striato-punctata’”’ but as noted is not that species. Williamson’s
figured specimen referred to above is probably the same as Terquem’s
species.

Var. selseyensis Heron-Allen and Earland, from off the southern
coast of England is probably a form of this with a somewhat more
open coil.

Test of medium size for the genus, somewhat compressed, periphery
subacute, margin entire, greatest thickness in peripheral view at the
umbilical regions which are not distinctly umbonate; chambers
numerous, distinct, not inflated, averaging about 15 in the last-
formed coil; sutures distinct, limbate, the retral processes elongate,

rod-like, occupying almost the entire height of the chamber; aperture,
a series of rounded openings at the base of the apertural face.

Diameter, 0.75 mm.; thickness, 0.30 mm.

D’Orbigny described this species from the “‘coast of Patagonia, to the
south of the Rio Negro.”’ It is distinct from the other species of this
region in its thickening at the umbilical region in peripheral view and
the subacute margin and distinct sutures.

Challenger, Zoology, vol. 9, 1884, pl. 110, fig. 9 (not 8, 10, 11).

Test of large size for the genus, compressed, periphery rounded,
margin very slightly lobulate, sides nearly parallel in peripheral
view, umbilical regions not umbonate but occupied by a group of
irregular raised areas; chambers numerous, 20 to 22 in the last-formed
whorl, slightly inflated; sutures sigmoid, indistinct except as marked
by the retral processes which are prominent, elongate, rod-like usually
15 or more, extending nearly the whole width of the chamber, the
interspaces deep; aperture, a series of rounded openings at the base
of the apertural face.

Diameter, 1.20 mm.; thickness, 0.35 mm.

D’Orbigny’s type locality for this species is given as “‘coast of
Patagonia, to the south of Rio Negro.”’ His specimen was evidently
a young, immature specimen. It has proved to be abundant and very
well developed in Doctor Schmitt’s collections from the Falklands.
at some stations the dominant species.

This is one of the most beautifully sculptured species of the genus
and hardly to be confused with any other. Its distribution appears to
be rather limited so far as material available shows, as it has occurred
only in the South Atlantic.

The young specimens are very close to the figure given by d’Orbigny,
but the adults have a more rounded periphery and more chambers.

Brady’s specimen from the Falklands noted above is this species
probably.

umbilical regions each with a large rounded boss, in peripheral view
protruding strongly beyond the outline of the test; chambers only
slightly inflated, distinct, averaging about 10 in number in the last-
formed coil; sutures slightly depressed, somewhat broadening toward
the inner end, marked also by the retral processes which are short,
and 10 to 12 in number; wall smooth, very distinctly perforate,
umbos of clear shell material, nearly transparent, with numerous
coarse tubules; aperture composed of several, small, rounded openings
at the base of the apertural face.

Diameter, 0.65 mm.; thickness, 0.30 mm.

D’Orbigny described this species from shore sands from Cuba and
Jamaica, recording it as common. It has a general West Indian
distribution.

The species is close to E. laniert (d’Orbigny), and is to be distin-
guished from it mainly by the less prominent retral processes, the
more depressed sutures, the more prominent umbos, and the smaller
number of chambers.

ELPHIDIUM LANIERI (d’Orbigny)

Carnegie Instit. Washington, 1919, p. 49.

Test of medium size for the genus, periphery subacute, margin
entire, not lobulate; sides convex in peripheral view giving a rhomboid
outline to the test, umbilical regions each with a large rounded boss
in peripheral view forming the greatest width of the test but con-
tinuous with the sides; chambers not inflated, distinct, numerous,
averaging 18 to 20 in the last-formed coil; sutures not depressed,
marked by the retral processes which are short, 10 to 12 in number
and slightly oblique, those of the earlier portion tending to merge
into oblique lines; wall smooth, distinctly perforate, translucent, the
bosses of clear material with numerous tubular perforations; aperture
composed of several, small, rounded openings at the base of the
apertural face.

Diameter, 0.60 mm.; thickness, 0.40 mm.

D’Orbigny’s types of this species were from shore sands of Cuba.
I have recorded it from the Late Tertiary of Rio Cana, Cercado de
Mao, Santo Domingo and from the gorge of the Yumuri River,
Matanzas, Cuba. The specimens I have noted from Porto Rico and
from the Miocene of Yellow River, Florida, belong under EF. sagrum
(d’Orbigny) as noted under that species.

In the earlier work on the Recent West Indian collections, I often
included £. lanierit and E. discoidale under the latter species.

Test of small size for the genus, periphery broadly rounded, margin
entire, not lobulate, sides convex in peripheral view, the last-formed
portion wider than the earlier portions, umbilical regions depressed;
chambers in the last portion slightly inflated, fairly distinct, 12 to
15 in the last-formed coil; sutures not depressed, except between the
last few chambers, marked by the retral processes about 10 in num-
ber, short and broad, continuous over the earlier portion of the test
to form ridges slightly oblique to the periphery; wall fairly thick,
perforate; aperture composed of a series of small, rounded openings
at the base of the apertural face.

Diameter, 0.55 mm.; thickness, 0.33 mm.

D’Orbigny’s types of this species were from shore sands of Cuba
where it is recorded as rare. It occurs very rarely in the Recent
collections from the West Indian region but seems to be more common
in the Late Tertiary of the same region, occurring in Florida, Cuba,
and Santo Domingo. The character of the distinct costae and the
shape in peripheral view will distinguish this species from others in

the region.

Test of medium size for the genus, strongly compressed, periphery
acute, with a narrow carina, somewhat lobulate, sides nearly parallel
in peripheral view, umbilical regions depressed, often with a small
central boss of clear shell material but in peripheral view not projecting
beyond the contour of the test; chambers distinct, 10 to 15 in the last-
formed coil, slightly inflated, especially in the last-formed portion;
sutures depressed, marked by the retral processes which are short,
about one-fourth the width of the chamber, 12 to 15 in number; wall
smooth, translucent, finely and distinctly perforate; aperture composed
of a series of small rounded pores at the base of the apertural face.

Diameter, up to 0.50 mm.; thickness, 0.15 mm.

The types of this species are from the Tortugas region off southern
Florida. The species is well distributed in warm, shallow water of
tropical regions. It is very different from von Miinster’s species
from the Oligocene of northern Germany. It is not as common
in the West Indian region as are several of the other species.

It apparently occurs in the Late Tertiary of the West Indian region.

ELPHIDIUM ADVENUM (Cushman), var. MARGARITACEUM, new variety

Variety differing from the typical mainly in the character of the
wall which in the variety is pearly and coarsely perforate, giving a
very distinctive appearance to the test.

E. advenum and somewhat similar specimens appear off the coasts of

Europe.

the very short, broad retral processes, averaging about 15 in number;
wall thin, translucent, smooth, conspicuously but finely perforate;
aperture composed of a series of small, rounded openings at the base
of the apertural face.

Diameter, 0.50 mm.; thickness, 0.20 mm.

D’Orbigny described and figured this species from shore sands of
Cuba and Jamaica. It has proved to be the most common species of
the genus in the general West Indian region. It is one of those species
which has been included under ‘‘ Polystomella striato-punctata”’ but is
very different from that species.

There is a considerable amount of variation in the specimens of this
species, in the shape, which is often somewhat longer than broad and
especially in the number of the chambers. In its general characters,
however, it is distinct from any other in the region.

D’Orbigny’s types were from “‘the coast of Patagonia, near the
Rio Negro, and also from the Falklands.”’ The species is common in
this region in the collections made by Dr. Waldo Schmitt. It is a
smooth, polished species with a fairly thick wall which may be dis-
tinguished from E. poeyanum (d’Orbigny) of the West Indian region
which somewhat resembles this. Both of these species have been
included under the name ‘‘ Polystomella striato-punctata” but are very
different from that species as has been noted.

28, Sci., 1885, p. 353, pl. 13, fig. 27.

Test of comparatively large size for the genus, compressed, periph-
ery broadly rounded, margin only slightly lobulate, umbilical regions
slightly depressed, smooth; chambers comparatively few, 10 to 12
in the last-formed coil, very slightly inflated; sutures distinct,
slightly depressed, marked by a double row of rounded pores, no
distinct retral processes; wall apparently sometimes double, often
slightly rugose; aperture consisting of a row of small rounded pores
at the base of the apertural face with occasionally a second row
slightly above it.

Diameter, 1.25 mm.; thickness, 0.50 mm.

The types of this species were described and figured by Parker
and Jones in Brady’s Shetland paper. The species is widely distri-
buted in the Arctic and North Atlantic; Gulf of St. Lawrence (Daw-

The double row of pores is due to a splitting of the canal from
the chamber cavity as shown by Brady’s figures in the Challenger

also has this same character.

Test of very large size for the genus, strongly compressed, periphery
rounded, slightly lobulate, umbilical regions slightly depressed and
the coils not completely involute, exposing some of the early coils in
the central region; chambers numerous, as many as 25 in the last-
formed coil, very slightly inflated; sutures distinct, very slightly
depressed, marked by a single or double line of pores; wall smooth;
aperture consisting of numerous small rounded pores in an inverted
V-shaped arrangement.

Diameter, up to 4 mm.; thickness, 0.30 mm.

Goés described this species from off Nova Zembla in shallow water at
about 15 fathoms. I have recorded typical specimens from Albatross
Station D 3600 in 156 fathoms in Bering Sea. It is to be looked for
in shallow water of the Arctic bordering on the North Atlantic.

Test similar to Elphidvum in general structure but trochoid, plan-

The species of this genus seem to be largely confined to the Pacific
region. No species are recorded from any part of the Atlantic.

Some of the fossil species of this genus become very abundant at
restricted localities. It was probably an attached form. There do
not seem to be any living Atlantic species.

0 BULLETIN 104, UNITED STATES NATIONAL MUSEUM
Family 25. CAMERINIDAE

Test generally planispiral and bilaterally symmetrical, in the early
stages involute, in the later stages often evolute; wall calcareous,
perforate; in the higher forms with a secondary skeleton and complex
canal system.

This family evidently started very early and there are Carboniferous
forms which apparently are the earliest beginnings of the group,
although the family did not reach its greatest development until
the Eocene. During that geologic period very large species were
developed and were very abundant, especially in the Eastern Hemis-
phere. In America, Operculina and Heterostegina were large and
abundant during the Middle and Upper Eocene, but the very large
complex Nummulites evidently did not migrate to this region. In
the shallow waters of the Indo-Pacific there are still living many large
forms related to the Eocene ones but in the western Atlantic the family
is almost wanting, the only genus represented in the collections
studied being Heterostegina, and that is evidently very rare.

Test bilaterally symmetrical, planispiral, complanate, usually all the
coils visible from the exterior, earlier coils sometimes involute; wall
calcareous, perforate, smooth or ornamented with bosses; aperture
single, at the base of the apertural face, median.

Lower Cretaceous to Recent.

There are many records, especially from the North Atlantic, referred
to ‘“‘Operculina ammonoides (Gronovius).”” This small species is not
an Operculina, but belongs with the Anomalinidae, and should be
known as Planulina ammonoides (Gronovius) and will be taken up in
the next part of this work.

True Operculinas are apparently not found in the Atlantic although
they occurred in the West Indian region abundantly in the Upper
Eocene and less so in the Oligocene. They are still persistent and
reach large size in the warm shallow waters of the Pacific.

Genotype, by designation.—Heterostegina depressa d’Orbigny.

Test similar to Operculina, the early chambers simple, later ones
divided into chamberlets; aperture consisting of a row of rounded
openings on the narrow apertural face.

Eocene to Recent.

This genus reached its climax in the Upper Eocene, and is now
represented in the Atlantic only in the West Indian region, and there
by but a single species. It is represented in the tropical Pacific by
large fine species which have still persisted and find their natural
habitat in warm waters of less than 30 fathoms.

Heterostegina depressa (part) H. B. Brapy, Rep. Voy. Challenger, Zoology,

Test comparatively small for the genus, close coiled throughout, not
complanate, greatest thickness in the umbonal region, thence sloping
to the subacute periphery; chambers strongly curved, narrow, the
outer portion divided up into a single row of chamberlets, those of
each chamber not connecting with one another; sutures distinct,
slightly limbate, not depressed; wall smooth; aperture consisting of a
few pores on the apertural face.

Diameter, about 2 mm.

D’Orbigny records this species from shore sands of Cuba and
Jamaica, but notes that he had but few specimens and that it is
apparently rare. Itis worthy of note that the two stations at the Dry
Tortugas, off Florida, where I found the species, were both in ab-
normally warm water for the region, and it may be that the species is
only holding on in such favorable localities. I did not find it in
material from Porto Rico, Cuba, or Jamaica in the collections I have
examined from these localities. A single typical specimen from
Albatross Station D-2758, from the east coast of Brazil, in 20 fathoms,
shows that it has the same general distribution as others of the West
Indian fauna. More collecting will undoubtedly increase its known
distribution in the region.

Cretaceous (?) Tertiary and Recent.

This genus as well as the whole family are characteristic of warm
shallow waters and generally coral-reef conditions. They often
occur in great numbers and show a great deal of variation. Double
and monstrous forms are not unusual. The student of this and allied
genera is referred to the work of Dreyer.® In the Atlantic the genus
is most abundant in the general West Indian region. Little is known
of it from the eastern tropical Atlantic.

Numerous writers have considered all the forms of Peneroplis as
varieties of a single species. Brady adopted this grouping in the
Challenger report, and many later authors have followed him. In
1915, Heron-Allen and Earland in their paper on the Recent Fora-
minifera of the Kerimba Archipelago, examined the early descrip-
tions and figures with the result that they used five distinct specific
names in their report. Some of these belong in other genera as now
recognized, and to them must be added certain species of d’Orbigny
based on material from the West Indies as well as one described by
Dr. J. M. Flint from material also of West Indian distribution.
For the stages of development in the microspheric and megalospheric
forms, the reader is referred to part 6 of Bulletin 71 of the United
States National Museum, where on pages 85 and 86, this develop-
ment is discussed.

In the West Indian region this species is the least common of all
those recorded when actual material is studied. The d’Orbignyan
species, P. elegans, seems to be identical with this species as commonly
understood. He recorded it from Cuba and Jamaica. I have re-
corded it from Jamaica, Porto Rico, and the Tortugas, and it occurs
at Habana. In the Indo-Pacific region and in the Mediterranean
this species is often abundant.

Test close coiled, completely involute, periphery subacute;
chambers 12 to 15 in the adult coil, low and broad, distinct; sutures
distinct, depressed, not limbate; wall smooth, not striate; aperture
a series of pores in the central portion and toward the base of the
apertural face.

D’Orbigny’s original locality was “‘not far from the mouth of the
Rio Negro, Patagonia,’’ where it was rare. Specimens from various
regions have been referred to this species, but in the material I have
had from the West Indian region, it is very rare and did not occur
at all in the abundant Bermuda material I have had.

Orbiculina adunca H. B. Brapy, (part), Rep. Voy. Challenger, Zoology, vol.
9, 1884, pl. 14, figs. 3, 4.

Test with the early portion close coiled and completely involute,
thickened, later portion assuming various shapes and variously
flaring but not becoming entirely embracing; chambers numerous,
but not many, 10 to 12 usually in the coils of the early portion,
usually somewhat higher than in most other species; sutures dis-
tinct, depressed; wall very smooth, thick, usually opaque; apertures
formed by the row of pores along the median line of the apertural
face.

Length, up to 1.5 mm.

This is by far the most common species of the genus in the warmer
regions of the Western Atlantic. D’Orbigny had it from Cuba
and Jamaica. I have had it from the north coast of Jamaica where
it was common. It is abundant in the shallow water collections of
the Tortugas, off Florida, and elsewhere off southern Florida north
at least to Biscayne Bay. It is the most common species of the
genus in Bermuda, the Bahamas, and Porto Rico, and probably is
widely distributed in the general West Indian region. Brady’s
specimens referred to above are from off Pernambuco, Brazil, and
are typical P. proteus. The Albatross obtained it in the same
region.

Some of the variations of this very plastic species are shown on
the plate and these could easily be much increased.

Test much compressed, the early portion coiled planispirally but
often partially evolute, later portion very much campanulate and
spreading out, reaching back on both sides toward the earlier chambers
but not entirely embracing; chambers distinct, very slightly inflated,
broad and low; sutures distinct, depressed, occasionally somewhat
limbate; wall very distinctly striate, the striae numerous and nearly
parallel to the periphery; apertures along the median line of the nar-
row apertural face.

This species is abundant in the Mediterranean and in the Indo-
Pacific, but does not, so far as I have seen, come into the West Indian
region, where it is replaced by the following species. In the eastern
Atlantic, what seem to be typical specimens are recorded from off
the coast of Great Britain, and very likely the species like other
Mediterranean ones extends out into the warmer parts of the eastern
Atlantic.

Test small, very greatly compressed, early portion planispirally
coiled, usually partially evolute, later portion broadening, forming a
flaring test; chambers distinct, long and low; sutures very distinct,
depressed; wall finely pitted but not striate; apertures in the central
line of the apertural face.

Length, usually less than 1 mm., often much less.

Holotype.—(Cushman Coll. No. 4840), from Montego Bay, Jamaica.

This species is next to P. proteus the most common in the West
Indian region. It occurs at numerous stations off the Tortugas and
the Florida Keys, at Bermuda and Jamaica. It is probably widely
distributed in the general West Indian region.

Peneroplis planatus, so far as I have seen, does not occur in the
western Atlantic and is apparently replaced by this species.

Karrer described a variety of P. planatus as var. laergata from the
Miocene of Kostej, but it is not the same as the West Indian species.
I have topotypes of Karrer’s variety for comparison. Brady’s speci-
mens, figured under this varietal name,’ are from Bermuda and
probably are P. bradyi.

1921, p. 63; Publ. 311, Carnegie Instit. Washington, 1922, p. 80.

Test much compressed, in the young close coiled and involute, the
chambers later becoming elongate, finally spreading out and embracing
the earlier portion of the test, forming in the adult completely annular
chambers; sutures distinct, depressed; wall entirely smooth; aperture
in the adult formed by pores about the median line of the periphery.

Diameter, up to 2.25 mm.

Flint described this species from shallow water of Key West Harbor,
Fla. I collected very typical specimens at this same locality, at the
Tortugas, off Jamaica and at Bermuda. It also occurs in the Baha-
mas and probably has a very wide general West Indian distribution.
It occurs also in the Late Tertiary of Cercado de Mao, Santo Domingo,
and in wells of southern Florida.

There are no records of its occurrence in the Pacific, and like P.
proteus is probably a species of the western tropical Atlantic.

It may be easily confused with Sorites compressa (d’Orbigny),
which may have developed from it. The Peneroplis, however, does
not have its chambers divided into chamberlets, a character easily
brought out by moistening the test.

Peneroplis (part) of AuTHORs.

Genotype, by designation —Dendritina arbuscula d’Orbigny.

Test similar to Peneroplis, the test usually thick and showing a
tendency to uncoil; aperture dendritic, in the apertural face.

Kocene to Recent.

The species of this genus are very highly developed in the Eocene,
but a few are found in the present oceans, especially in the Indo-
Pacific region. I have not found any Atlantic species belonging to
this genus.

Peneroplis (part) of AUTHORS.

Genotype, by designation.—Spirolina cylindracea Lamarck.

Test similar to Peneroplis, thick; early chambers close coiled,
usually not completely involute, later ones uncoiled; aperture rounded
terminal.

Cretaceous (?) to Recent.

This genus is especially well developed in the Upper and Middle
Eocene, but occurs also Recent, especially in warm, shallow waters of
the Indo-Pacific. There are but two species, so far as the material
examined shows, in the western tropical Atlantic, and these are very
rare.

Test with the earliest chambers close coiled but making only a
small portion of the test which in the adult is cylindrical or very
slightly tapering, circular in transverse section the chambers becoming
as high as broad; sutures distinct, slightly depressed; wall longitudin-
ally striate, translucent, thin; aperture consisting of one or more
pores in the middle of the terminal face.

FORAMINIFERA OF THE ATLANTIC OCEAN 43

Length of western Atlantic specimens not over 0.50 mm.

This form has usually been referred to Lamarck’s ‘‘P. cylindracea”’
based on Eocene specimens from France. An examination of the
French specimens shows that Lamarck’s species is thicker and heavier,
and the wall has distinct, sharply raised costae, altogether different
from the species that occurs in the present ocean, at least in the
western Atlantic. These specimens which are very rare from Jamaica
and the Tortugas are referred to Batsch’s recent species, the types of
which are from the Mediterranean.

A comparison of other recent material referred to Lamarck’s
species should be made with Eocene material from the type locality.

wall longitudinally striate; aperture consisting of a series of independ-
ent pores in the central portion of the apertural face.

This species, often abundant in the Mediterranean and Indo-
Pacific, is very rare in the western tropical Atlantic. Woodward
records it from Bermuda, and I collected it there also, but it was
very rare. It occurs at the Tortugas, but there also it is very rare.
I found it rare also at Montego Bay, Jamaica.

This is evidently a widely distributed form occurring but in small
numbers in the general West Indian region.

Genotype, by designation.— Monalysidium sollasi Chapman.

Test with the early chambers close coiled, later ones uncoiled in a
rectilinear series; wall imperforate, smooth or with vertical rows of
minute tubercles; aperture circular, terminal, sometimes with a short
neck and lip.

Recent.

The early chambers of specimens are easily broken, and it is usual
to find only the uniserial chambers present after samples are washed.
The constrictions at the sutures leave the test very weak. The neck
and lip that are developed are similar to those seen in so many of the
uncoiled genera of various families of the foraminifera.

FORAMINIFERA OF THE ATLANTIC OCEAN 45

So little is known of this genus that it is difficult to specifically
place specimens. Brady’s specimens figured in the Challenger Report
are from the Cape Verde Islands. Chapman’s figures seem to be
different in shape and surface characters from those of Brady and
from those found at the Tortugas and Porto Rico. The specimens
from the West Indian region are all of the same species, but consist
of a rectilinear series only, and all appear to be broken. One specimen
shows two tubular orifices at one end instead of one as is usual.
Specimens were rare at all stations. I did not find it at Bermuda.

following chamber, perforate; aperture in the early stages, as in
Peneroplis, a narrow slit, then a series of pores, one to each chamberlet,
in a slight depression in the median line of the peripheral face.

Miocene to Recent.

This species is very abundant in the West Indian region, and very
much less so in the Indo-Pacific. In the western tropical Atlantic,
it is often the dominant species in comparatively shallow water.

FORAMINIFERA OF THE ATLANTIC OCEAN 47

The original specimens of Fichtel and Moll are recorded from the
Mediterranean and the Arabian Sea. There is much question as to
its occurrence in the Mediterranean, and it may be that the authors
had West Indian material from some source. The material from the
Red Sea that I was able to see in the Brady collection has certain
characters that seem to distinguish it from West Indian specimens.
In the western Atlantic there may be two living species in addition
to that often referred to as Orbiculina compressa d’Orbigny which is
here included under Archaias. These species should all be studied
in detailed section and the relationships of the microspheric and
megalospheric forms determined. The species occurs fossil in the
West Indies, Panama, and Florida.

Test circular in outline, the early portion with several layers of
chamberlets and the chambers much thicker than in later growth
which is annular and the chamberlets in a single or double layer,
greatest thickness of the test formed by the earlier involute portion;
wall calcareous, imperforate, except in the proloculum and second
chamber; aperture in the adult formed by a marginal row of pores,
either single or double.

Diameter up to 2.50 mm.

The original material described by d’Orbigny came from the West
Indies and was recorded as rare in Cuba, more common at Guadeloupe
and St. Thomas, but abundant in Jamaica. It has occurred fossil
in the Late Tertiary of Jamaica, Florida, and Panama.

It is not the same as Sorites marginalis Lamarck and can be dis-
tinguished from that species especially by the thickening of the
earlier portion. A discussion of this species has already been given ®
with the early stages in development.

This species has often been included with Archaias angulatus
but the two are distinct. A. angulatus, as shown in the figures of
that species, does not become completely annular and is a much
thicker, heavier species.

Taramellina Munier-Chalmas is probably a synonym of Sorites.

Under this genus are included those species which have a single
layer of annular chambers divided into chamberlets in the adult
often referred to ‘‘Orbiculina” and ‘‘Orbitolites.”’

Genus AMPHISORUS Ehrenberg, 1838

Amphisorus Eurensera, Abhandl. k. Akad. Wiss. Berlin, 1838, p. 130.—
CusuHMaN, Special Publ. No. 1, Cushman Lab. Foram. Res., 1928, p. 221.
Orbitolites (part) of AuTHoRs, (not Lamarck).

Genoholotype—Amphisorus hemprichit Ehrenberg.

Test discoid, planispiral in the early stages, at least of the micro-
spheric form, later annular, completely divided into chamberlets;
typically in two layers, those of each annular chamber communicating
with the adjacent ones of the preceding and succeeding annular cham-
bers and those of the two layers communicating; wall imperforate
except in the very earliest chambers; apertures in a double, alter-
nating line along the periphery.

Miocene to Recent.

Bradyella Munier—Chalmas is probably a synonym of Amphisorus.

Test much compressed, circular in outline, the early chambers,in
the microspheric form coiled planispirally, soon widening and becom-
ing annular, in the megalospheric form the annular chambers beginning
at once after the large rounded or oval proloculum; chambers in two
layers in the adult, and each divided into many chamberlets, the
chamberlets of each newly added series alternating with those of the
preceding series; wall imperforate except in the proloculum and
succeeding chamber which are finely porous; apertures at the periphery
of the chamberlets in a double series as are the chamberlets.

Diameter, up to 2 mm.

The species, if those of the West Indian region and those of the
Indo-Pacific and Mediterranean are the same, has a wide distribu-
tion. In the West Indies it occurs in great numbers attached to the
leaves of the short eel-grass, Posidonia, which grows in great profusion
in shallow water.

I have examined the types of Amphisorus hemprichivi in the Ehren-
berg collection in Berlin, and it seems that Carpenter’s species is a
synonym in which case Ehrenberg’s name will take precedence.

Specimens were found in Jamaica which had megalospheric young
in the outer chambers of the parent test.

Genoholotype.—Craterites rectus Heron-Allen and Earland.

Test probably attached in life, the whole composed of numerous
layers of chambers, the basal layer without trace of spiral develop-
ment, form in side view contracted above the base, and the outer
end broadening and convex; chambers very numerous; wall calcare-
ous; outer surface with numerous small rounded openings.

Recent. South Pacific.

Family 27. ALVEOLINELLIDAE

Test imperforate except the proloculum and second chamber;
general shape of the test fusiform, coiled about an elongate axis;
chambers completely involute, divided into chamberlets; apertures
numerous, in one or more rows on the face of the last-formed chamber.

The foraminifera belonging to this family are highly developed, and
have probably been derived from such forms as Peneroplis by the
division of the close-coiled forms into chamberlets and an elongation
of the axis. Some of the Eocene species of Borelis are much com-
pressed in the line of the axis and for the exception of the division
into chamberlets are close to Peneroplis. The greatest development
of the family seems to have been in the Eocene when they were
widely distributed in both the Eastern and Western Hemispheres.
With the exception of a single small species of Borelis, the distribution
of the family in the present oceans is mostly confined to the Indo-
Pacific where large specimens are often very abundant in shallow
warm water of coral reef regions.

The single species from the West Indian region is all that is recorded
from this part of the Atlantic. Brady gives records from the Cape
Verde Islands, but I have not seen the material.

Observer, vol. 4, 1893, p. 78.

Test small, completely involute, globular or slightly fusiform;
chambers distinct, usually four in a coil, divided into elongate cham-
berlets but the chamberlets not again subdivided, growing edge low
and connecting the two umbilici; wall imperforate, milky-white;
apertures consisting of a single row of rounded pores, one to each
chamberlet, in the apertural face.

Diameter, 0.45 mm.

This species is rare in the West Indian region. Brady gives the
West Indies, Bermuda, and Cape Verde Islands for Atlantic localities.
D’Orbigny’s types are from Cuba. I have collected it on the north
coast of Jamaica, at a few stations in the Tortugas region, and at
Bermuda.

So far as I have seen, material from the Indo-Pacific, the material
to be referred to Borelis melo (Fichtel and Moll), is definitely larger
and usually has more chambers in the coil.
