INTRODUCTION. 


This paper is the fifth part of a work the intent of which is to 
describe and illustrate the Foraminifera of the Atlantic Ocean, espe- 
cially 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 Carribbean 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 Chilostomellidae 
and Globigerinidae. ‘The first part, issued in 1918, included the fam- 
ily Astrorhizidae, the second part, issued in 1920, included the family 
Lituolidae, the third part, issued in 1922, included the family Textu- 
lariidae; and the fourth part, issued in 1923, included the family 
Lagenidae. Other parts to be issued will include the families Rota- 
liidae, Nummulitidae, and Miliolidae.

THE FORAMINIFERA OF THE ATLANTIC OCEAN, 


CHILOSTOMELLIDAE AND GLOBIGERINIDAE. 


By JosrrH AUGUSTINE CUSHMAN, 
Of Sharon, Massachusetts. 


INTRODUCTION. 


This fifth part of the work on the Atlantic Foraminifera deals with 
the Chilostomellidae and Globigerinidae. The same arrangement of 
data as that used in the earlier parts is here followed. As most of 
the species are pelagic at some time in their life history the distribu- 
tion shows less well-marked faunal areas than in the bottom-living 


forms. 
SYSTEMATIC PART. 


A systematic presentation of the various groups follows: 
Family 6. CHILOSTOMELLIDAE. 


Test calcareous, conspicuously punctate, chambers usually some- 
what inflated, irregularly coiled, the last-formed chamber in the 
various genera making up a large portion of the last-formed volution; 
aperture usually a curved opening between the base of the chamber 
and its predecessor, sometimes terminal. 

This family is represented in the present oceans by three genera, 
Chilostomella, in which each chamber takes up 180° of the periphery 
as added; Allomorphina, in which it takes up typically 120°; and 
Seabrookia, which has a somewhat more definitely coiled appearance. 

As Chilostomella is somewhat alternating in dorsal view, it has been 
placed near the Textulariidae, but in many ways the family seems 
nearer the Globigerinidae. 

The family also includes the genus Ellipsoidina Seguenza, which 
occurs in the later Tertiary, but is not known as a Recent genus.

Description.—Test composed of a series of chambers in a coil, each 
chamber making a half coil of 180° and embracing so that but a 
small part of the preceding chamber is visible from the exterior; 
wall smooth, finely perforate, either thin and transparent or thick 
and opaque; aperture at the inner margin of the ventral face of the 
chamber curved, often with a slightly upward-turned lip. 

This genus has been described as composed of an alternating series - 
of chambers, but in reality it seems to be a coiled test in which each 
chamber takes up 180° of the volution. The peculiar form of the 
test is distinctive, as is the form of the aperture. Chilostomella 
ovoidea Reuss is thin walled and very widely distributed; OC. grandis 
Cushman is known as yet only from the Pacific about the Philip- 
pines. The species described from the London Clay as Lagena 
(Obliquina oviformis) Sherborn and Chapman ! seems to be a species 
of Chilostomella and should be known as Chilostomella oviformis 
(Sherborn and Chapman). The geological range of the genus there- 
fore is from the Eocene to the present oceans. 

From the very wide distribution of C. ovoidea and its thin test it 
might be supposed to be pelagic, but little is known of it except as 
a bottom-living species.

Description.—Test composed of several chambers in a coil, each 
chamber 180° from the preceding, the chambers all visible from the 
dorsal side, but the two last-formed ones making up nearly the whole 
surface of the test; chambers increasing very rapidly in size as 


1 Journ. Roy Micr. Soc., 1886, p. 745, pl. 14, figs. 19 a-d. 


FORAMINIFERA OF THE ATLANTIC OCEAN, 3 


added, the last-formed one the largest and covering most of the 
preceding ones; sutures not depressed, rather indistinct; wal! smooth, 
translucent, usually very thin and conspicuously punctate; aperture 
a curved, somewhat arched opening between the base of the chamber 
and the preceding one, often with a slightly thickened somewhat 
flaring lip. 

Length up to 1 mm. 

Distribution.—This species seems to have a very wide distribution 
in both tropical and temperate seas and at considerable depths. 
It has many characters which seem to indicate a possibility for 
pelagic condition. It is a very thin-walled species compared with 
Chilostomella grandis Cushman, which is certainly a bottom-living 
form. There are numerous Albatross records, as the accompanying 
table shows, and the species is also known from the eastern Atlantic, 
especially off the British Isles. It occurs also in the Indo-Pacific 
at scattered stations.

Description.—Test made up of a few ovate chambers in a coil, 
each chamber making up 120° of the volution so that but three 
chambers are visible from the exterior; wall thin, translucent, 
finely punctate; aperture a narrow slit at the base of the chamber. 

The genus is closely related to Chilostomella and bears somewhat 
the same relation to it that Triloculina does to Biloculina. 

The geological range of the genus is apparently somewhat greater 
than that of Chilostomella, going back to the Upper Cretaceous.

Description.—Test composed of several ovate chambers, coiled, 
each chamber making 120° of the volution and embracing so that 
but three chambers are visible from the exterior; chambers longer 
than wide, inflated; sutures somewhat depressed; wall smooth, con- 
spicuously punctate, usually thin and translucent; aperture a narrow 
curved opening at the base of the ventral margin of the chamber 
between it and the previously formed adjacent chamber. 

Length about 0.40—-0.60 mm. 

Distribution.—About the only Atlantic record for this species 
seems to be that of Goés, who records it from off Spitzbergen. Other 
records for the species as a living form are from the Indo-Pacific.

Description.—Test composed of a series of chambers, each par- 
tially or entirely inclosing the preceding one; wall thin, hyaline, 
perforate; aperture terminal, rounded, with a slightly thickened lip. 

The records for this genus are all from recent seas, but are widely 
scattered in the various oceans.

end of the segment; chambers usually five in number.” 

Length 0.30 mm. 

Distribution.—Wright described this species from two stations off 
the southwest coast of Ireland, 374 fathoms (69 meters), off Castle- 
town, County Cork, Ireland, and 345 fathoms (631 meters), latitude 
51° 2’ north, longitude 11° 27’ west. Herron-Allen and Harland 
record ‘‘a single quite typical specimen from Station 12” of the 
Clare Island region. They also make the following note: “Itis 
much more abundant in some of the deeper Goldseeker dredgings 
in the North Sea and the Norwegian fjords, and is undoubtedly a 
deep-water form.”’ The only other record seems to be that of Side- 
bottom from the Australian region. The other species S. pellucida 
H. B. Brady, is known only from the Indo-Pacific. 

No specimens of the genus have been noted in the Albatross 
dredgings from the western Atlantic. 


Family 7. GLOBIGERINIDAE. 


Test composed of numerous chambers, usually much inflated, 
arranged typically in a trochoid coil, but in some species becoming 
planospiral; often umbilicate; wall calcareous and perforate, usually 
with a more or less regular reticulation and in perfect specimens in 
some species with long slender spines; aperture either large and simple 
or with numerous accessory openings. 

This family is represented by comparatively few genera and 
species, yet in individuals they are probably the most abundant and 
widely distributed of all the Foraminifera. They make up a very 
high percentage of the Globigerina-ooze which covers a large propor- 
tion of the bottom of the ocean basins down to 2,000 or 2,500 fathoms 
(2,658 to 4,572 meters). Fossil species in the Cretaceous and Ter- 
tiary often make up a large percentage of certain limestones, show- 
ing the abundarice of members of this family through various periods 
of later geological time. 


6 BULLETIN 104, UNITED STATES NATIONAL MUSEUM. 


Many of the species are pelagic at least at some stage in their life 
history and occur in enormous numbers in the ocean currents such 
as the Gulf Stream. <A few species occur in cold waters, but the 
greatest development seems to be in the Tropics or subtropical 
waters, except where these are widely distributed by ocean currents. 

The tendency in the family, as in all pelagic foraminifera, is to 
develop aform in which the protoplasm of the tést may have free access 
to the surface. This is accomplished in part by a large umbilical 
aperture or in other species by numerous accessory apertures leading 
to various parts of the surface. The protoplasm in the pelagic forms, 
as has been shown by numerous authors, is very vesicular and is far 
greater in bulk than the test. In some of the species long spines are 
developed which radiate from the surface and apparently help in 
supporting the protoplasm. These are easily broken and are there- 
fore usually wanting in bottom specimens. In the interior chambers 
of various species they may be often seen. 

Another adaptation to pelagic life is the taking on of a generally 
spherical character. This is best seen in Orbulina universa, but a 
nearly spherical shape occurs in Globigerina conglobata, which is 
roughly spherical. All the species have inflated chambers. 

While the species are widely distributed, especially the pelagic 
ones, there are others which seem to be evidently bottom-living 
forms and do not have the broad distribution of the former. In the 
western Atlantic there seem to be certain forms which differ with 
latitude or bottom temperature, and although these are not here 
separated, it is not impossible that it may later be possible to do so. 


Genus GLOBIGERINA D’Orbigny, 1826. 


Globigerina D’OrB1eNyY (type, G. bulloides D’Orbigny), Ann. Sci. Nat., vol. 
7, 1826, p. 277.—H. B. Brapy, Rep. Voy. Challenger, Zoology, vol. 9, 
1884, p. 589.—CuaApMAN, The Foraminifera, 1902, p. 205.—CusHMan, 
Bull. 71. U. S. Nat. Mus., pt. 4, 1914, p. 5. 

Deservption.—Test composed of numerous inflated chambers 
arranged typically in a trochoid manner, but which in later develop- 
ment may be variously arranged; wall typically coarsely perforate, 
reticulate; aperture large, arched, at the base of the inner margin of 
the chamber, in some species opening on the umbilicus, in others 
with numerous accessory openings. 

This genus has a number of very well characterized species, largely 
those described by Brady in the Challenger report and a few others. 
They make up the larger constituent of the typical Globsgerina-ooze 
and form also a large element in Pteropod-ooze. There are evi- 
dently a considerable number of bottom-living species which should 
be more closely studied, for from the present studies it seems that 


FORAMINIFERA OF THE ATLANTIC OCEAN, 7 


there may be varieties or species which have a definite distribution in 
the western Atlantic. The species of Globigerina can hardly be con- 
fused with any others, as the form of the test, coupled with the 
peculiar reticulate surface, should at once distinguish them. 


GLOBIGERINA BULLOIDES D’Orbigny. 
Plate 2, figs. 1-4. 


From a study of the western Atlantic Albatross material the prob- 
lem of what to refer to G. bulloides D’Orbigny has become a trying 
one. So many forms have been assigned to this species from all 
parts of the present oceans and from so many fossil formations that 
a reference to the various figures show a very wide range. There 
are very few specimens in all the Albatross stations examined that 
can at all be assigned to this species as defined by D’Orbigny in his 
Modele. Variety triloba Reuss is also very nearly wanting. There 
are many young specimens of other species that seem to be referable 
to G. bulloides, but it is easy to determine in a very large series of 
specimens that these are really young of other species and not adults. 
I have given in the accompanying table a list of the slides which have 
been assigned to G. bulloides, but these are often marked with a 
question. I have come to the conclusion that G. bulloides if present 
is a very rare species in the western Atlantic.

Description.—Test composed of numerous inflated chambers 
arranged in a nautiloid spiral; chambers all visible from above, 
umbilicate below, with only the chambers of the last volution visible, 
usually 5 to 6 in number; wall reticulate; apertures of the chambers 
opening into the umbilical cavity. 

Diameter, 0.50-0.80 mm. 

Distribution.—From the records G. dubia is a very widely dis- 
tributed species. That more than one species may be passing under 
this name is a very evident conclusion from the study of published 
figures. I have placed under it here three or four forms which may 
later prove to be distinct. In the Gulf of Mexico there are specimens 
with a rather high test and a deep umbilical region very different from 
the ordinary form of the species. Such forms may later be found to be 
distinct. In other parts of the area also there seem to be varietal 
forms which need further study before a final disposition of them can 
be made. This must be left to future dredgings. - 

Especially in such species as this where the original specimens were 
fossil ones a study of the type material is necessary to make clear 
just what the author had in mind and whether this should apply to 
so great a mass of recent material from many regions. 

GLOBIGERINA SUBCRETACEA Chapman. 

Under this name Chapman has placed the recent species which 
has been referred by many authors as Globigerina cretacea. It is 
probable that the recent species is not the same as the Cretaceous 
one. In the Albatross material I have not attempted to dist'.guish 
this from G@. dubia Egger.

Description-x—Test regularly spiral, trochoid, consisting of two or 
three volutions; early chambers inflated, subspherical, later chambers 
much elongated, the tip usually rounded; wall reticulate; aperture 
opening into the central umbilical opening; or in the elongate, adult 
chambers making up the larger part of the base of the chamber, 
the area of attachment being very much reduced. 

Diameter of single Atlantic specimen slightly less than 1 mm. 

INstribution.—This seems to be typically a species of the Pacific and 
Indian Oceans. Brady in the Challenger report recorded it from 
three stations in the South Atlantic. Flint recorded a single specimen 
from the Gulf of Mexico, Albatross station D2377, and I have another 
specimen from this same material. It is therefore very rare in the 
North Atlantic.

sutures depressed; aperture single, on the inner margin of the last- 
formed chamber in the umbilical area. 

Diameter up to 0.60 mm. 

Distribution.—D’Orbigny originally described this species from the 
West Indian region. It has since been recorded from very widely 
scattered areas in the present ocean basins. In the present paper 
it has probably been included under G. dubia. Until D’Orbigny’s 
type specimens can be studied it may be impossible to determine just 
what this West Indian species may be.

Description.—Test composed of numerous inflated chambers 
arranged in a trochoid spiral test of about three volutions, the last- 
formed one usually composed of four chambers, the dorsal side of 
the test flattened or slightly convex, the ventral side strongly convex; 


FORAMINIFERA OF THE ATLANTIC OCEAN. Hs 


test in side view about as high as broad, very finely reticulate, some- 
times almost smooth, being the smoothest of the common species 
of the genus; aperture a long arched opening, running from the 
umbilicus nearly to the dorsal edge of the chamber, somewhat 
broadest toward the ventral side. 

Diameter usually 0.50-0.80 mm., sometimes slightly more. 

Distribution —A tabulation of the Albatross records and the 
plotting of them on the Atlantic map has shown a very distinctive 
distribution for this species in the western Atlantic. Unlike most of 
the other species of the genus, it occurs very sparingly in the Tropics. 
There are three records for the Caribbean, two in the Gulf of Mexico, 
three off Florida, one off the coast of Georgia, and, except for one off 
Brazil, the remainder of the records, nearly a hundred in number, are 
off the northeastern coast of the United States. 

This species therefore is one which is apparently for the most part 
a bottom-living species or else its distribution would probably be 
similar to that of G. conglobata, G. aequilateralis, and G. sacculvfera.

ser. 5, vol. 1, 1878, p. 485, pl. 21, figs. 10 a-c. 

Globigerina bulloides D’OrBiaNy, var. borealis H. B. Brapy, Proc. Roy. 
Soe. Edinb., vol. 11, 1882, p. 716. 


Description.—Test coiled in a depressed spire, the general form 
subglobular, the last-formed volution consisting of four chambers, 
the sutures somewhat depressed; aperture an arched opening along 
the ventral margin of the inner face of the last-formed chamber. 

Diameter up to 0.30 mm. 

Distribution.—This species is an arctic one so far as published 
records show. According to Brady it is common within the Arctic 
Circle, but occurs only in bottom dredgings, not in the pelagic gather- 
ings. Pearcey records it from the Faroe Channel, and Heron-Allen 
and Earland from a single station west of Scotland and in the Clare 
Island region. I have failed to find it even in the colder areas along 
the northeastern coast of the United States. Pearcey records it 
from the Antarctic. Egger records it from numerous stations in 
various parts of the world, and there are a few other scattered rec- 
ords, but it may be questioned as to whether it really occurs in its 
typical form except in the arctic or subarctic regions, with occasional 
occurrences in cold waters somewhat farther south.

Desecription.—Test composed of several inflated chambers arranged 
in an elongate trochoid spire of about three volutions, each with 
three chambers; walls reticulate, with spines in pelagic specimens; 
aperture an arched opening at the umbilical border of the chamber, 
and in the later chambers this is supplemented by two or more 
nearly circular openings on the upper border of the chamber near its 
connection with the preceding chambers; color of the early chambers, 
sometimes all the chambers, pink. 

Length about 0.75 mm.; diameter about 0.50 mm. 

Distribution.—This was originally described by D’Orbigny from 
the West Indian region. In the Caribbean, the Gulf of Mexico, and 
in the path of the Gulf Stream this species is often very abundant. 
It has a very brightly colored test when well preserved and specimens 
are fairly fresh. 

It becomes less well developed in more northern bottom samples, 
and although its range extends to the western coast of Europe, it 
was always taken in the tow nets in the Tortugas region, which is on 
the border of the Gulf Stream. 

Outside the West Indian region the red color seems to be largely 
wanting and it may be that the species in its typical form is confined 
to the Atlantic. 

Pelagic specimens have a distinctly spinose test.

Description.—Test subglobular, the early chambers arranged in a 
compact spiral; in the adult the last three chambers become much 


FORAMINIFERA OF THE ATLANTIC OCEAN. 19 


flattened and extended laterally so that they form nearly the whole 
surface of the test; wall strongly reticulate, the angles between the 
reticulations often being almost spinose; aperture at the inner margin 
of the chamber near the umbilicus and with several rounded secondary 
apertures along the contact between the last-formed chamber and the 
previous ones to which it is adjacent. 

Diameter up to or exceeding 1 mm. 

Distribution.—This is essentially a pelagic species and its distribu- 
tion seems to be largely determined by ocean-current movements, 
especially of those currents which sweep away from tropical regions. 
The Gulf Stream distributes this species, which is most abundant and 
best developed in the Caribbean. Specimens found farther north 
are often somewhat smaller and few, if any, of them show the large 
fine tests developed in the Tropics. 

This species has the test well modified for a pelagic existence. ‘The 
generally spherical shape of the test with the large aperture and num- 
erous accessory openings allow free egress of the protoplasmic con- 
tents which seems necessary to the floating of the somewhat heavy 
test. 

The early development of the test is a trochoid spire which soon 
becomes modified to the subspherical form. It is one of the most 
easily recognized species of the genus.

Description.—Test composed of numerous chambers, the early 
ones similar to Globigerina bulloides, but very soon developing acces- 
sory openings, especially on the dorsal side of the test where the new 
chamber meets the previous one; early chambers nearly spherical, 
the later ones becoming somwhat elongate and compressed, the final 
chamber in fully developed or senescent specimens often much 


22 BULLETIN 104, UNITED STATES NATIONAL MUSEUM. 


flattened and the outer end with numerous projecting points; wall 
strongly reticulate, except in the final chamber, which is often much 
smoother than the preceding ones; aperture large, on the ventral 
side near the umbillicus, with numerous other secondary openings 
about the inner border of the chamber. 

Diameter up to and sometimes exceeding 1 mm. 

Distribution.—This, seems to be a truly pelagic species and its 
distribution therefore very dependent upon surface movements of 
the ocean waters. Like certain of the other pelagic species, the best 
development seems to be in the Caribbean. There in the bottom 
samples there are very fine large specimens. 

The last-formed chamber is much modified in several ways. In 
the adult or senescent specimen this last formed chamber becomes 
very large, the periphery often with lobate projections which are 
often of bizarre shapes. The chamber itself on account of the very 
large aperture, often taking up most of the base, is somewhat loosely 
attached. The surface of this chamber also, instead of being coarsely 
reticulate as in the earlier chambers, is much more finely reticulate 
or even almost smooth. = 

This early stages of this species might be mistaken for @. bullovdes, 
but the accessory openings on the dorsal side are developed or at 
least suggested at a very early age.

Description.—Test oblong or evate, composed of several chambers 
more or less irregularly arranged, inflated, the later chambers being 
added on the periphery of the test without regard to the spiral 
arrangement of the earlier ones; wall reticulate; aperture on the 
basal side of the inner margin of the chamber, but also are added 
one or more accessory apertural openings on the upper side of the 
test, especially in the added last chambers. 

Diameter up to 1 mm. 

Distribution.—Specimens which can be referred to this species are 
rare in the Albatross dredgings. It is recorded from both the North 
and South Atlantic by Brady. 

There seems to be some doubt as to whether this should be recog- 
nized as a valid species. It has very much the appearance of an 
abnormal form in specimens which I have found both in the Atlantic 
and Pacific. Some of the specimens of G. rubra where abnormal 
chambers are developed give much the appearance of the specimens 
of G. helicina figured by various authors.

Description.—Test composed of numerous inflated chambers ar- 
ranged in a bilaterally symmetrical, planospiral coil of one and a 
half to two volutions; chambers increasing rapidly in size as added, 
usually five to six visible in side view; sutures much depressed, giving 
a lobulated contour; wall reticulate, often with broken spines; aper- 
ture large, an arched opening at the base of the chamber. 

Diameter up to 1 mm. 


26 BULLETIN 104, UNITED STATES NATIONAL MUSEUM. 


Distribution.—The typical form of this species, that with the coil 
decidedly open, is found in abundance in the Caribbean and generally 
in the path of the Gulf Stream. Farther north there are bottom 
specimens which have the more involute character of the variety I 
have described as var. involuta.? 

The typical form develops to a considerable size and it is possible 
in some specimens to see between the last whorl and the preceding 
one in side view. In the early development the test is somewhat 
trochoid, but this soon gives rise to a planospiral arrangement of the 


chambers.

GLOBIGERINA CONCINNA Reuss. 


Under this name Egger* records and figures specimens from nu- 
merous localities in the eastern Atlantic, between Madeira and 
Cape Verde Islands, Cape Verde, West- Africa, West South Africa, 
etc. The form figured as far as can be made out is more flattened 
than the typical G. dubia. There is little in the western Atlantic 
that I should feel justified in referring to this species. 


GLOBIGERINA OCELLATA (Ehrenberg). 


Kggex* records and figures specimens from the eastern Atlantic 
and elsewhere as ‘“‘Globigerina (Rotalia) ocellata Ehrenberg.” The 
figures are not such as would allow a definite determination of just 
what Egger had that he placed under this name. 


GLOBIGERINA DIPLOSTOMA Reuss. 


Keeer° records and figures under this name specimens from a num- 
ber of localities in the Atlantic as well as elsewhere. It belongs in 
the group which I have here included under G. dubia Egger. Egger’s 
records are from the eastern Atlantic from the coast of Portugal 
southward along the coast of Africa. 


GLOBIGERINA QUADRILOBA D’Orbigny. 


The ventral side of a specimen which is referred to this species is 
figured by Egger.© He gives an Atlantic record from off West 
Africa, but it is not definite at all just what he may have had.

GLOBIGERINA REGULARIS D’Orbigny. 


Egger’ figures specimens under this name. <A number of the Ga- 
zelle stations from which he obtained specimens are in the eastern 
and southern Atlantic. I have had no specimens that I could refer 
to this species. 

GLOBIGERINA LINNEIANA (D’Orbigny)? 

Brady in the Challenger report (p. 598) refers D’Orbigny’s Rosalina 
inneiana to Globigerina. The original specimens were from shore 
sands of Cuba. There are numerous Cretaceous specimens referred 
to this name following Brady’s use of it in the Challenger report. 
No such form has appeared in the Albatross collections.

Description.—Test in the early stages composed of several Globige- 
rina-like chambers rapidly increasing in size as added, finally entirely 
surrounded by the adult chamber which is spherical, with numerous 
small pores, and one large circular orifice, or occasionally more than 
one; wall reticulated, in living condition with long, fine spines. 

This genus is evidently derived from Globigerina, as a later devel- 
opment for the young Globigerine stages have often been found within 
the spherical chamber. Just what becomes of the earlier chambers 
in the empty globular chamber as usually found is not entirely known 
but it is probably resorbed. They are more often found in smaller 
than in larger spherical chambers. 

According to Chapman the geological history goes back to the 
pre-Cretaceous.

Description.—Test in its early development consisting of a series 
of Globigerina-like chambers, the adult developing a globular cham- 
ber about this early Globigerina-like portion; surface usually finely 
reticulate, with a small pit at the bottom of each reticulation and 
one larger circular aperture forming the main opening into the 
interior; in the living condition the surface develops long spines 
from its exterior. 

Diameter up to 1 mm. 


30 BULLETIN 104, UNITED STATES NATIONAL MUSEUM. 


Distribution.—Specimens of this species occur very widely dis- 
tributed, as would be expected of a species which is so well adapted 
for a pelagic life. It is very finely developed and very abundant 
in the bottom samples from the Caribbean, but good specimens are 
found in most bottom samples where Globigerinidae occur at all. 
The specimens outside the Tropics, however, are usually smaller. 

The adaptation to the pelagic condition is first of all brought 
about by the spherical form. There are a great many small open- 
ings beside the ordinary punctae and one opening of still larger 
size, thus allowing easy access for the protoplasm to the exterior. 
In a living pelagic specimen there are developed very numerous 
elongate spines from the exterior and these evidently serve in some 
way to support the extended protoplasm. 

The young is Globigerine in character and shows that Orbulina 
belongs to that group and is a genus derived from a Globigerine 
ancestry. The addition of the spherical chamber comes as the last 
character in its development. There are many spherical chambers 
in which these early chambers do not appear. This may be from 
two causes. One may be that the earlier chambers are resorbed as 
occurs elsewhere in the animal kingdom. ‘The other is that these 
may be microspheric forms of the species and the earlier develop- 
ment retained as is the case elsewhere among the foraminifera, the 
smaller globular chambers without the early stages being the mega- 
lospheric form of the species. Whether the plahular chamber grows 
larger at all after its development is a mooted question. nce 
are often found specimens, especially among the larger ones, in 
which several layers of the test are developed. These may possi- 
bly be additions on the exterior of the smaller test represented by 
the inner layer. 

In some specimens two large chambers are developed instead of 
one, a condition that would be easily accounted for on the basis 
of development of a final globular chamber after a series of coiled ones.

Brady refers to this species some very coarsely reticulate specimens 
from the following stations: Challenger, off Culebra Island, West Indies, 
390 fathoms (713 meters), and from Valorous stations in the North 
Atlantic, station 9 in 1,750 fathoms (3,200 meters), and station 15 
in 1,485 fathoms (2,716 meters). 

I have had Albatross dredgings from near the Challenger station 
recorded above, but have not seen specimens which I could refer to 


this species.

as added and the sutures much depressed; wall finely perforate, 
nearly smooth except for long rodlike spines with parallel sides, the 
edges of which are serrate, especially toward the base; aperture very

34 BULLETIN 104, UNITED STATES NATIONAL MUSEUM: 


Pistribution.—This is a truly pelagic species, having been taken in 
all the great ocean basins, especially in tropical and subtropical 
waters. In the Albatross bottom samples it occurred only in those 
from the Caribbean, where it seldom occurred in any considerable 
numbers. It is recorded from the coast of the British Isles in the 
warm area of the Faroe Channel (Pearcey), and a smgie specimen 
was found at 750 fathoms (1,370 meters) off the southwest of Ireland 
(Wright). 

The plate of figures of this species is from the Challenger report, as 
all the bottom samples are largely without spines.

Genus CANDEINA D’Orbigny, 1839. 


Candeina D’OrBIGNY (type, C. nitida D’Orbigny), in De la Sagra, Hist. 
Fis. Pol. Nat. Cuba, 1839, ‘‘Foraminiféres,’”’ p. 107.—H. B. Brapy, Rep. 
Voy. Challenger, Zoology, vol. 9, 1884, p. 622.—Cuapman, The Fo- 
raminifera, 1902, p. 209. 

Description.—Test generally trochoid, usually with the spire 
somewhat compressed and the later chambers often irregular; cham- 
bers numerous, rapidly increasing in size as added, inflated; wall 
usually clear and translucent, in old-age specimens occasionally 
thickened and opaque; apertures numerous, elliptical in form, placed 
in a somewhat regular manner along the sutural lines between the 
chambers. 

This genus described by D’Orbigny in his Cuban Monograph is 
often abundant in some of the bottom samples of the West Indian 
region, especially in the Caribbean. It is recorded from the other 
great ocean basins, but never seems to be abundant elsewhere than 
in the West Indian region from which it was first described. 

In spite of its being in general form like certain other members of 
the Globigerinidae, its early development occasionally has very much 
the character of some of the Rotaliidae. The early chambers are 
often of a dark-brown color, such as is found in numerous genera of 
the Rotaliidae, and there seems*to be no real reason why it should 
not be placed in that family rather than in the Globigerinidae.

Micr. Soc., 1918, p. 152.—Cusuman, Bull. 100, U. S. Nat. Mus., vol. 4, 
1921, p. 296. 

Deseription.—Test composed of numerous inflated chambers in a 
trochoid spiral, rather rapidly increasing in size as added; wall 
smooth, finely punctate; sutures depressed; aperture consisting of 
a series of rounded elliptical openings at the junction of the chambers 
along the sutures. 

Diameter usually less than 1 mm. 

Mistribution.—The map of distribution of the Albatross specimens 
is an interesting one. The largest number of stations are from the 
‘Caribbean and also by far the largest number of specimens are from 
this same region. Specimens occur at the stations south of the 
Equator in tropical waters of the coast of Brazil. There are also 
a very few specimens from scattered stations along the Florida 
coast and northward as far as the Carolina coast, but no specimens 
have been noted northward from Cape Hatteras. 

The species was originally described by D’Orbigny from shore 
sands of Cuba and it is probably found in such conditions throughout 
the West Indies, for it is a pelagic species. The adaptation of the 
nearly spherical form and instead of one large aperture the large 
number of elliptical openings along the sutures allowing free access 
of the protoplasmic contents to the exterior are both for pelagic 
conditions. 

There are numerous records for this species from other parts of the 
world, but the general West Indian region seems to be its typical 
habitat.

Description.—Test composed of a few chambers arranged in an 
irregular spire, the later chambers especially much inflated, increas- 
ing rapidly in size and embracing, a few only visible from the ex- 
terior; wall perforate; aperture an arched opening at or near the inner 
margin of the chamber, often with a calcareous, toothlike process 
“partially closing the opening. 

According to Chapman, the genus ranges back to the Cretaceous, 
but in the Tertiary it becomes more abundant. 

The two common recent species are very unlike.

Description.—Test subspherical, the exterior usually formed by 
the last three chambers, entirely covering the earlier chambers, 
which are irregularly spiral; sutures very slightly depressed; wall 
smooth and polished, thick, minutely perforate; aperture compara- 
tively small, consisting of an arched semicircular opening, usually 
nearly closed by a broad flat semicircular tooth. 

Diameter up to about 1 mm. 

Distribution.—W hile specimens of this species occur in the Albatross 
dredgings from the coast of Brazil to the latitude of Cape Cod, the main 
distribution seems to be near the latter locality. There are scattered 
specimens, as the table shows from off Brazil, the Caribbean, and 
the Gulf of Mexico; but the great mass of records are in the region 
between Cape Hatteras and Cape Cod, on the northeastern coast of 
the United States. 

The species is apparently not known as a pelagic one. While it has 
in general a spherical form, there are no secondary openings and the 
single aperture is nearly closed by a large flat tooth. This does not 
correspond with the character of free accessibility of the protoplasm 
to the surface seen in most pelagic species.

FORAMINIFERA OF THE ATLANTIC OCEAN. 39 


Description.—Test inflated, usually somewhat longer than broad, 
composed of a few chambers, the earlier ones irregularly spiral, but 
in the adult three chambers usually making up the entire visible 
portion of the test; the fully developed test is marked by fissure-like 
sutures, the edges of which are slightly cariate, or sometimes becom- 
ing fimbriate and nearly closing the fissure; wall thick, in the young 
translucent but with large perforations, in the adult usually opaque 
and the perforations very large and conspicuous, sometimes even 
making the test reticulate and rough; aperture an arched opening into 
the chamber from the deep fissure near its base. 

Diameter up to 1 mm. but in adults sometimes exceeding this. 

Disiribution.—The Albatross records for the western Atlantic show 
this species well scattered over the area from off Brazil just south of 
the Equator to latitude 40° north. It is known as a pelagic species 
and its distribution thus roughly corresponds in the Albatross samples 
with the general condition of ocean-current movementgin the North 
Atlantic. 

The best developed specimens are from the Caribbean. Those 
from other regions are usually less well developed and represent 
young individuals in many cases. 

The young is generally in the form of a trochoid spire, but the 
irregular shape is soon taken on. The smooth surface and very 
coarse punctae will distinguish the young from any of the species of 
Globigerina. In the young the sutures are not depressed, but as 
growth progresses the sutures become much depressed and finally 
in well-developed or senescent specimens the sutural areas become 
much cleft and the edges of these become fimbriate.

Pullenia PARKER and JoNEs (type, P. sphaeroides (D’Orbigny)), in Car- 
penter, Parker, and Jones, Introd. Foram., 1862, p. 184.—H. B. Brapy, 
Rep. Voy. Challenger, Zoology, vol. 9, 1884, p. 614.—Cuapman, The 
Foraminifera, 1902, p. 207.—CusHMAN, Bull. 71, U.S. Nat. Mus., pt. 4, 
1914, p. 20. 

Description.—Test composed of several chambers arranged in a 
planospiral or oblique nautiloid more or less involute spiral, chambers 
not greatly inflated, only those of the last-formed volution visible; 
wall smooth, perforations small and indistinct; aperture a curved 
opening at the base of the inner face of the chamber. 

The genus is only superficially like the others of the Globigerinidae. 
P. obliquiloculata is more nearly like them than are the others, being 
more inflated, having a large aperture, and being rather coarsely 
perforate. 

The other two recent species much more resemble species of 
Nonionina, but they do not have any of the characteristic complex 
structures of the Nummulitidae. 

P. obliquiloculata is a pelagic species, as much of its structure 
indicates, and may really differ generically from the other two.

Pullenia bulloides Rruss, Denkschr. Akad. Wiss. Wien, vol. 25, 1866, p. 150. 


Description.—Test subspherical, sometimes compressed laterally, 
composed of numerous chambers, making three or four volutions, 
each consisting of four chambers, entirely embracing so that the last 
volution only is visible from the exterior; surface of the test smooth; 
wall very finely but indistinctly perforate; aperture a narrow semi- 
circular curved slit near the base of the ventral face of the last-formed 
chamber and the previously formed volution. 

Diameter usually less than 0.50 mm. 

Distribution.—This is a rare species in the western Atlantic collec- 
tions. The small size makes it easily overlooked, although it as a rule 
occurs in the “‘floatings”’ if at all. The few stations in the accompany- 
ing table representing the Albatross records show that it has usually 
occurred as single specimens in the material examined. The only 
station at which it occurred in any numbers is in cold water, and as 
this is not known as a pelagic species nor does it show any special 
adaptations for pelagic life, it may be inferred that it is most at home 
in deep and cold waters. The desirability of placing this species and 
the following one with P. obliquiloculata seems very questionable.

Pulienia sphaeroides PARKER and Jones (part), Philos. Trans., vol. 155, 


1865, p. 368, pl. 17, fig. 53. 


Description.—Test close coiled, planospiral, bilaterally symmetri- 
cal, biconvex, the last-formed coil usually consisting of five chambers, 
varying between four and six; peripheral edge broadly rounded; sur- 
face smooth, shining, the chambers very slightly inflated; sutures 
correspondingly depressed; aperture an elongate, narrow semicircular 
slit between the base of the last-formed chamber and the previous 
volution. 


FORAMINIFERA OF THE ATLANTIC OCEAN, 43 


Diameter up to 0.75 mm. 

Distribution.—As in the preceding species, the distribution seems to 
be in cold, deep waters as arule. There is a single record from off the 
coast of Brazil, a very few from the Gulf of Mexico and the Caribbean, 
and one from off the southeastern coast of the United States. In 
contrast to this there is a large number of stations from the north- 
eastern coast of the United States, in cold and deep water. 

This seems, as far as the literature shows, to be a bottom-living 
species.

291, Carnegie Inst. Washington, 1919, p. 40; Bull. 100, U.S. Nat. Mus., 
vol. 4, 1921, p. 299. 

Description.—Test obliquely nautiloid, subglobular, inaequilateral, 
the outer volution consisting of about five chambers and covering 
the early portion of the test entirely; chambers inflated but the sut- 
ures very slightly depressed; wall smooth, distinctly punctate, 
shiny; aperture elongate, narrow, curved, between the ventral face of 
the last-formed chamber and the adjacent volution with the chamber 
wall forming a rounded lip. 

Diameter from 0.50 mm. to nearly 1 mm. 

Distribution.—This is a truly pelagic species and its distribution is 
almost ocean wide. In the Albatross collections it is widely scattered 
over the region in which dredgings were made. 

The coarsely punctate test and large aperture fit the species for a 
pelagic existence, but make it seem very, different from either P. 
sphaeroides or P. quinqueloba in most of its characters. Their generic 
differences would seem to be a matter worthy of consideration.
