PREFACE.

The purpose of this catalogue is to record Jbe;results of \aiiJ examina-
tion of a portion of the bottom material obtkmed' during the dredgiug
operations of the U. S. Fish Commission sf earner; Albwifo'$s,'' pnil at tlie
same time to furnish a convenient book of Reference for those who are,
or may become, sufficiently interested to continue the study of this
material.

The examination, while very far from exhaustive, has been pursued
with greater or less diligence, as time and opportunity offered, for sev-
eral years. Material from about one hundred and twenty-five stations
has been carefully studied, and specimens from more than a hundred
localities have been preserved and identified. Of these localities,
fifty-eight are in the North Atlantic Ocean, twenty-one in the Gulf of
Mexico, seven in the Caribbean Sea, one in the South Pacific, and
five in the North Pacific. The depths at these stations vary from 7 to
2,512 fathoms.

The figures in illustration are from photographs of mounted speci-
mens on exhibition in the U. S. National Museum, Division of Marine
Invertebrates. A uniform enlargement of about 15 diameters has
been maintained in the figures, sometimes at a sacrifice of detail in
the smaller specimens which would have been made clearer by the use
of a higher magnifying power, but for the purpose of identification it
is believed to be more useful to mark distinctly the relative size of the
objects. The exhibition series has been mounted expressly for public
display. The individuals of each species are attached in various atti-
tudes to the bottom of the shallow cavity of a concave, blackened disk
of brass. For security each disk is provided with a removable fenes-
trated brass cap having a top of thin glass. These disks are arranged
in concentric rows upon a large circular metal plate which occupies
the place of the stage of an ordinary microscope. The circular plate
is given both a rotary and a to-and-fro movement by means of a fric-

tion roller and a rack and pinion, so that all the mounts may be suc-
cessively brought under the microscope. The specimens thus arranged
are inclosed in a box having a glass top, through which the objective
of a microscope projects.1

In the following catalogue the classification of Mr. H. B. Brady has
been followed, as presented in " The report on the Foraminifera col-
lected by H. M. S. Challenger," and his definitions of families and
genera have been appropriated bodily. The analytical table is also
compiled chiefly from the above-mentioned report. The descriptions
of species have been prepared after study of the reserve series as well
as of the typical specimens reproduced in the illustrations.

The localities given are only those from which specimens have been
taken in selecting the series exhibited and in reserve, and do not
profess to represent the distribution of the species.

A supplementary table gives the latitude, longitude, and depth of
water of the stations referred to in the catalogue.

THF. FORAMINIFERA.

The Foraoninifrra are minute aquatic, mostly marine, animals, having
semifluid bodies, composM -jf. granular protoplasm, inclosed in shells
or "tests" either secreted by the animal or built up of available foreign
material, such as mud, sand, sponge spicules, or dead shells. In zoologi-
cal classification they belong to the Ixhizopod group of the Protozoa,
and are distinguished from other members of the group by the single
character of the reticulated form assumed by their pseudopodia when
extended.

These minute animals are interesting objects of study, geologically
and biologically as well as esthetically. As objects of beauty they
arrest the attention of even the casual observer by the delicacy of
their structure as well as the symmetry and variety of their forms.
Geologically they are of interest because they are among the most
ancient and abundant of fossils and also the most efficient of rock
builders. Biologically they are instructive examples of the powers and
possibilities of an individualized bit of protoplasm — "a little particle
of apparently homogeneous jelly, changing itself into a greater variety
of forms than the fabled Proteus, laying hold of its food without mem-
bers, swallowing it without a mouth, digesting it without a stomach,
appropriating its nutritious material without absorbent vessels or a
circulating system, moving from place to place without muscles, feeling
(if it has any power to do so) without nerves, propagating itself without
genital apparatus, and not only this, but forming shelly coverings of a

symmetry and complexity not surpassed by those of any testaceous
animals."1

From the resemblance of some of the shells of the foramiuifera to
those of the nautilus, they were for a long time regarded as minute
cephalopod mollusks; that is, among the highest of the invertebrates,
and it was not until the year 1835 that their true nature was discovered
and announced by M. Dujardin to the French Academy of Sciences.
Since that time the study of this order of animals has been pursued by
able naturalists, and the results of their investigations appear in a
voluminous literature. Much yet remains to be learned of the life his-
tory of the animal, but its zoological position is established and its
importance in the economy of nature recognized.

As fossils the foraminifera are common in all geological systems from
the Devonian upward, but they are especially abundant in Mesozoic and
Cenozoic time. The chalk and many of the most extensive limestone
beds are formed principally of their remains. As to present habitat,
their shells are found wherever dredgings are made, all over the ocean
floor except in the polar regions. A few species are "pelagic;" that is,
they are found living at or near the surface of the water, but the weight
of evidence is in favor of the conclusion that the vast majority of them
pass all stages of life at the bottom, where they are found. In the
experience of the naturalists of the Albatross it was rare to find any
but the most minute and thin-shelled forms in the surface dredgings,
and still more rare for any to be taken in the "wing nets" that were
usually attached to the dredging apparatus.

The living foraminifer is a minute bit of viscid, granular protoplasm,
without organs or tissues, without differentiation of substance into outer
membrane and inner contents, and in most instances without evident
nucleus or contractile vesicle. A nucleus has been recognized in a few
individuals, and hence this characteristic element of most living cells
is inferred to be present in all the members of the order. Like other
Rhizopods, it has the power to protrude any parts of its body as "pseu-
dopodia," for the purpose of locomotion or the prehension and absorption
of food. It differs, however, from the other Khizopods in that the
pseudopodia do not necessarily remain distinct, but flow together when-
ever they touch one another, forming sometimes an elaborate and
extended network of protoplasmic threads, which, however, may be
readily retracted and flow again into the body mass, leaving no indica-
tion of their previous existence.

How the function of nutrition is accomplished and the nature and
condition of the organic material used as food by these minute animals
is not yet determined. Without doubt the pseudopodia are capable of
seizing and inclosing small organic particles with which they may come
in contact, and any part of the protoplasmic body, of which the pseudo-
podia are but temporary extensions, is able to digest and assimilate the

nutritive portion. To furth'er account for the necessary food supply, it
is believed that the Foraminifera absorb organic matter held in solu-
tion by the sea water. This theory is the more easily accepted since
we know that they have the power to separate inorganic matter (car-
bonate of lime in particular) from its solution, with which to construct,
wholly or in part, their shells.

Of the process of reproduction little is known beyond the fact of
multiplication by gemination and fission. Every part of this simple
animal being sufficient unto itself for purposes of nutrition and growth,
it follows that a fragment of the protoplasmic body cast off from the
parent becomes at once a new individual and the possible founder of a
fresh colony. But it is not in accord with what we know of the life
histories of other living things that this process of subdivision or prop-
agation by cuttings or shoots can go on indefinitely. It is more likely
that some kind of sexual reproduction takes place, the manner of which
is yet to be demonstrated.

The most striking characteristic of this simple, semifluid animal, of
indefinite and changeable shape, is its ability to construct a shell or
test of definite form in which to shelter itself. This shell or test may
be irregular, simple, and rude in construction, or symmetrical and of
great delicacy and beauty, in variety of forms rivaling the shells of the
Mollusca, of which it was long thought to be a diminutive example.

Structurally there are three quite definite and distinct types of tes-
taceous covering. The first, to begin with the lowest and least common,
is the "chitinous" test — a thin, transparent, yellowish or brownish
membranous investment secreted by the animal. It has one or more
general apertures, but is not perforated with fine foramina, and there
is no means of communication between the inside and outside of the
test except by the general apertures. The foraminifera with this kind
of shell have been grouped in the single family of Gromidce. As a rule
they inhabit only fresh or brackish water. They have not been found
in deep-water marine collections, and do not appear in the following
catalogue.

The second type is the so-called "arenaceous" test. This is an
investment constructed of grains of sand, or of the dead shells of other
foraminifera, or of sponge spicules, or even of mud, cemented together
more or less firmly by means of a calcareous cement secreted by the
animal. Usually it has one or more general apertures of comparatively
large size, and in addition there may be minute orifices between the
sand grains, or other substances of which the test is constructed,
through which the delicate threads of protoplasm can be projected.
The surfaces may be rough and coarse or smooth and highly finished,
according to the fineness of the material used and the amount of cement
deposited in the crevices and angles between the grains. When con-
structed of mad these tests are found, in some instances, to have a
chitiuous base, which maintains the shape of the investment.

DESCRIPTIVE CATALOGUE OF RECENT FORAMINIFERA. 255

The third type of structure is a true shell, composed almost entirely
of carbonates of lime and magnesia separated by the animal from their
solution in the sea water, and fixed in solid form. It is through the
agency of the foraminifera principally that the limestone, which is con-
stantly being dissolved by rains and carried by rivers to the sea, is
restored to the solid crust of the earth. Of these "calcareous" shells
there are two kinds, quite distinct in appearance, known as "porcel-
lanous" and " hyaline." The former are usually white, opaque, shining
with the peculiar luster of porcelain, and "imperf orate;" the latter arc
transparent, glassy, and "perforate," more or less densely, by minute,
parallel, unbranched tubes for the passage of delicate pseudopodia. In
both kinds there are usually one or more comparatively large, general
apertures. Surface marking, or "ornamentation," is common in both
the porcellanous and hyaline shells. In the former they take the form
of striatious or pittings, more or less regular and conspicuous; in the
latter, of ridges, tubercles, or spines, of clear nontubular shell-substance,
varying constantly in number and prominence among individuals of the
same species.

Architecturally the first and most obvious division of these shells is
into single-chambered (inonothalamous, or unilocular) and many-cham-
bered (polythalamous, or rnultilocular). While the primitive form of
both the single and many chambered shells is evidently globular, yet
the possibilities of ultimate conformation, depending chiefly upon direc-
tion of growth, are very great. Thus a mouothalamous shell, beginning
as an incomplete spherical chamber, may become ovate, flask-shaped,
spindle shaped, star-shaped, or tubular, and the tubular form may be
straight, curved, coiled, or quite irregular. And these forms pass from
one into another by quite insensible degrees. The polythalamous shell
is a consequence of the process of reproduction by "gemmation," as
the other is of reproduction by "fission." In this case the growing
sarcode pushes outside the initial chamber until at a certain stage it
builds a new wall around itself, while still maintaining connection with
the parent cell. This second segment may give origin to a third, and
so on until a colony is established, each offspring occupying an apart-
ment added to the parental home. It is easy to see that the style of
architecture of these tenements may be almost infinitely varied by vary-
ing the shape and position of these annexes. Each annex may have
any of the forms of the mouothalamous shells or any modification of
them, and the arrangement may be in straight or curved lines, in con-
centric circles or planospiral coils, in single or double series spirally
coiled, in two or three alternating series not spiral, or even in an irreg-
ular and disorderly mass.

Usually in the development of the polythalamous 'shell each succes-
sive segment uses the party walls of the preceding segments, so far as
they may be available, in the construction of its own annex, but in
some of the higher types of the hyaline series it will be found that

256 REPORT OF NATIONAL MUSEUM, 1897.

each chamber has a complete wall of its own, thus making double par-
titions between them. In some of these higher types there is devel-
oped also what is called a " supplemental skeleton," which consists of
a deposit of shell-substance on the outside of the original wall, thereby
adding to its thickness, filling in the hollows between the segments and
at the umbilici, and sometimes growing out into protuberances of
various shapes. This supplemental skeleton is generally traversed by
a set of canals or sinuses — passages left during the deposit of the
shell-substance, and probably occupied by threads of sarcode during
the life of the animal.

The separation into families, genera, and species of a group of ani-
mals like the foraminifera, where variation is the rule and passage from
one type to another is by a sliding scale and not even by a series of
steps, is extremely difficult, and must always remain unsatisfactory in
some particulars; but for convenience of reference, if for no other
reason, a classification of some sort is demanded, and various schemes,
which it is unnecessary here to enumerate, have been put forth to bridge
the difficulty. In all these schemes the primary divisions are founded
upon the structure of the test as above described — that is, whether
chitinous, arenaceous, or calcareous, and whether perforate or imperfo-
rate. Beyond these distinctions, which seem to have a physiological
foundation, there is nothing upon which to base a classification but the
form of the test, which, as we have seen, is never determinate enough
to permit of the establishment of fixed boundary lines. Generic and
specific names of foraminifera, therefore, must not be considered as
having much zoological value, but only as convenient titles applied to
certain typical forms around which many varieties may be grouped.
And it must be remembered that, however elastic the definitions of
species, or even genera, there will often be a margin of doubt, and
the determination of place in the classification must be left to the
preference of the individual observer.

A few words concerning the manipulation of material and specimens
may be of assistance to those beginning the study of the foraminifera.

Collection of recent shallow- water forms may be made from shore
sands, from the anchor and chains, and especially from the " chain
lockers " of ships, from sponge sand, and by means of boat dredges from
the shallow waters of the coast. Deep-water forms are only obtain able
by special apparatus, such as is used in deep sea sounding or in purely
scientific explorations of the ocean bed. The specimens may be freed
from mud by the process of decantation — that is, repeatedly agitating
in water, and, after a very brief period to allow subsidence of the shells,
pouring oif the turbid surface water. Or the material may be put in a
bag made of fine bolting cloth and the bag shaken in a bucket of water.
The remaining foraminifera, mixed with more or less sand, pteropod
shells, sponge spicules, and debris of various sorts, should then be
thoroughly dried, bottled, and labeled.

For examination of the dried material a dissecting microscope stand,

DESCRIPTIVE CATALOGUE OF RECENT FORAMINIFERA. 257

with a good ticromatic lens magnifying about 10 diameters, is most
convenient. A small quantity of the material in a shallow watch glass
blackened on the under side, being placed under the lens, is carefully
inspected, and when a specimen is found which it is desired to pre-
serve it may be readily removed by means of a very fine camel's hair
pencil slightly moistened between the lips. Transfer of specimens
should be attempted with the moistened pencil only, as the use of forceps
is certain to crush the delicate shells.

For preservation of the identified specimens in numbers for study
nothing is better than wooden slides of regulation size — 1 by 3 inches.
These may have either a concavity drilled in one side nearly through
the wood and painted black, or a hole bored entirely through the slide
and one side covered with heavy blackened paper. A removable cover
to this little cavity may be cut from a thin sheet of mica and held in
place either by a spring clamp or by slipping it under the thin paper
front of the slide, which is left uuglued about the center for that
purpose.

To make a section the specimen should be attached in the desired
attitude to the face and near the end of a glass slip by means of the
minutest drop of liquid glue. The attitude of the specimen must be
carefully preserved until the glue has set. The shell is then covered
with chloroform or xylol balsam, which may be made to penetrate the
chambers of the shell and be rapidly hardened by the application of
direct heat up to the boiling temperatnre. Superfluous balsam being-
cut away, the shell supported by the balsam is rubbed lightly upon a
hone, kept thoroughly wet with water, until the desired section is
exposed. The balsam is then dissolved away by chloroform, and the
glue by water, and the specimen mounted.

The manner in which specimens shall be mounted will depend upon
the preferences or ingenuity of the preparator, and the arrangements he
may make for the storage of his collection. If a cover-glass is used it
should not be sealed on, as the underside of the glass is almost certain
to "sweat" sooner or later, and obscure the specimen. It may be worth
while to say that for the attachment of the shells to any surface the
author has not found anything better than microscopists' gold size.
The best instrument for transferring the minute drop of adhesive
material of Avhatever kind to the point where the shell is to be attached
is the finest obtainable sewing needle, the eye end inserted in a slender
handle and the point broken off at the thickest part of the needle.

The literature of the subject is very large, though most of it is to be
found in journals of natural history and transactions of societies. With
Carpenter's "Introduction to the Study of the Foraminifera," Brady's
"Beport on the Foraminifera collected by H. M. S. Challenger" and
Sherborn's "Index to the Genera and Species of the Foraminifera," the
student will be able to begin work in an intelligent manner and to find
references to all that has been published on this subject up to the most
recent date.

(Plate 40, fig. 3.)

This species has the same general characters as B. depressa and its
variety serrata, but the last two chambers are more or less separated at
the sides, giving the shell the appearance of rupture from internal

a whole shell resting upon its side, the other being a transverse section
of a similar shell standing on end. The few specimens exhibited show
a passage from one form to the other by well-defined steps, but with a
large number of specimens the gradation is so easy that it becomes
indefinable. The series illustrates the difficulties of classification in
this order of animals.

periphery of the shell. If but one spine is present, that is generally a
prolongation of the final segment.

Locality. — Collected at the same station as A. coronata.

Genus RUPERTI.A.

Test columnar, growing attached by a slightly-spreading base; seg-
ments numerous, spirally arranged; aperture at the inner margin of
the final segment.

RUPERTIA STABILIS Wallich.
(Plate 79, fig. 4.)

Irregularly flask-shaped, having a moderately-inflated body, a short,
thick neck, and an expanded lip. The lip is formed by the spreading
base by which the shell adheres to some other body. The neck is
formed by about two superimposed convolutions; the body by the
inflated segments of the succeeding convolutions; walls thick and
coarsely perforated; aperture at the inner edge of the final segment.
Length, 1.5 mm. (^ inch), more or less.

Localities.— North Atlantic and Gulf of Mexico (stations 2530, 2383),
956 and 1,181 fathoms.

Subfamily TUN'OIPORHSTJE.

Test consisting of irregularly-heaped chambers, with a more or less
distinctly spiral primordial portion.

Genus GYPSINA.

Test free or attached, spheroidal or spreading; structure acervuline,
radiating, or laminated; chambers rounded or polyhedral, coarsely
perforated.

GYPSINA INH^ERENS Schultze.
(Plate 79, fig. 6.)

Adherent; contour discoidal, more or less distorted according to the
form of the surface to which it was adherent; composed of numerous
subglobular segments irregularly heaped together, except at the very
beginning, where a brief spiral arrangement is perceptible on the under
side; walls coarsely perforated; no general aperture. Diameter, about
1.25 mm. (-^ inch).

Localities. — Off Florida Keys, Straits of Yucatan, and Exuma Sound
(stations 2641, 2358, 2629), 60 to 1,169 fathoms.

Family X. NUMMULINID^E.

Test calcareous and finely tubulated; typically free, polythalamous
and symmetrically spiral. The higher modifications all possessing a
supplemental skeleton and a canal system of greater or less complexity.

Subfamily FOI.YSTOMELLIN^C.

Test bilaterally symmetrical ; nautiloid, lower forms without supple-
mental skeleton or interseptal canals ; higher types with canals open-
ing at regular intervals along the external septal depressions.

Genus NONIONINA.

Supplemental skeleton absent or rudimentary; no external septal
pores or bridges; aperture a simple curved slit.

NONIONINA BOUEANA d'Orbigny.
(Plate 79, tig. 5.)

Oval, compressed, bilaterally symmetrical; composed of numerous
long, narrow, curved segments coiled in a close flat spiral, the last con-
volution completely inclosing the others; outline smooth; sutures flush;
surface granular about the umbilici, which are depressed; no intersep-
tal pores. Diameter, about O.G mm. (-4-i0- inch).

Locality.— Gulf of Tokyo, 9 fathoms.

NONIONINA SCAPHA Fichtel and Moll.
(Plate 80, fig. 1.)

Oval, compressed, symmetrical, smooth, not granular about the
umbilici; segments comparatively few, increasing rapidly in size; face
of the terminal segment broad and round. Diameter, about 0.4 mm.
(eV inch).

Localities.— Panama Bay, coast of Yucatan, and Gulf of Tokyo
(stations 2805, 2358), 9 to 222 fathoms.

Genus POLYSTOMELLA. .

Supplemental skeleton, septal bridges, and canal system more or
less fully developed ; canals opening externally at the umbilicus and
by a single or double row of pores along the siitures. Aperture a
v-shaped line of perforations at the base of the septal face.

POLYSTOMELLA STRIATOPUNCTATA Fichtel and Moll.

(Plate 80, fig. 2.)

Discoidal, bilaterally symmetrical.; final convolution incloses all the
others; margin rounded; Avails finely perforated ; septal bridges dis-
tinct; a single row of pores along the sutures. Diameter, about O.G mm.
(/o inch).

NAT MUS 97 22

338 REPORT OF NATIONAL MUSEUM, 1897.

Localities. — Coast of Yucatan, North Atlantic (stations 2358, 2530,
2614), 10 to 956 fathoms.

POLYSTOMELLA CRISPA Linneeus.
(Plate 80, fig.- 3.)

shell-substance more or less porous. Diameter, about 0.7 inm. (-3\ inch )

Locality. — Not recorded.

Subfamily IJ^TTJMIVITJIl.ITIlSrjE.

Test lenticular or complanate; lower forms with thickened and finely
tubulated shell-wall, but no intermediate skeleton; higher forms with
inter septal skeleton and complex canal system.

Genus AMPHISTEGINA.

Test spiral, lenticular, inequilateral; chambers equitant, the alar pro-
longations on one side simple, on the other divided by deep constric-
tions so as to form supplementary lobes. Shell-wall thickened near the
umbilicus and finely tubulated, but presenting no true canal system.

AMPHISTEGINA LESSONII d'Orbigny.
(Plate 80, fig. 4.)

Lenticular, somewhat unequally convex on the two sides; margin
angular; surface smooth; segments numerous, narrow, bent, simple on
the upper side, but constricted on the inferior side, and sharply bent
backward; aperture on the under side of the last segment. Diameter,
about 1.5 mm. (^ inch).

Localities. — North Atlantic, coast of Yucatan, Gulf of Mexico (sta-
tions 2415, 2629, 2641, 2363, 2370), 9 to 1,169 fathoms.
