PART IV.

CATALOGUE OF THE FRESH-WATER FISHES OF
TROPICAL AND SOUTH TEMPERATE

AMERICA.

BY

C. H. EIGENMANN,
INDIANA UNIVERSITY.

IN the following list are enumerated the orders, families, genera and
species of fishes inhabiting the fresh waters of the West Indies,
South America, and Middle America south of a line joining the Rio
Panuco on the east and the Rio Presidio near Mazatlan on the west. The
list attempts to be complete to June, 1909.*

Under each genus will be found the synonyms and the type of the
genus, and the total range of its species. The range will be the sum of
the distributions of the species enumerated, except in cases of genera
having extralimital species.

Under each species are given its synonyms and the geographical dis-
tribution.

Opposite each species, except in the case of the Characins and species
dealt with in the Patagonian section of this work, will be given a refer-
ence which will connect this work with the literature on the species.

A catalogue of the fresh-water fishes of South America was published
by Eigenmann and Eigenmann in the Proceedings of the United States
National Museum, 1891, and a catalogue of the Middle American species
in the same serial for 1892. Free use has been made of these catalogues.
The task of bringing the work down to date has been greatly lessened
by the following works of recent years :
Jordan & Evermann, Fishes of North and Middle America. Bull. U. S.

Nat. Mus., 47, Washington, 1896-1898.

*The entire MS. was completed to 1906. Delay in publication has enabled me to bring the
catalogue down to June, 1909. In consequence of bringing the catalogue down to 1909 some
discrepancies between the preceding and following lists of species will be found. An especially
large number of additions are made to the Characins and the fauna of Guiana.

These papers, exclusive of the MS. monograph on the Characidae, are
referred to under the name of the author and the page. Other papers are
quoted by the author, year of publication and the page. The full titles
may readily be found in the bibliography at the end of the Catalogue.

All fishes recorded from fresh water are enumerated. In tropical
America many marine species enter fresh water. Some of these do not
go far beyond the mouths of rivers, others ascend streams several thou-
sand miles. Perhaps some of the marine species enumerated should have
been excluded, probably others should have bee'n added. The author will
be very glad to be informed of any omissions or errors of any sort.

In order to emphasize the Pacific slope fauna the species from this area
are in heavy type. To readily distinguish the Amazonian species, these
are preceded by an A.

relationships, and for the purpose of discussing the geo-
graphical distribution, it will be better to recognize a
larger number of genera. My estimate of the character
of these can best be expressed by the following key, in
which I have followed to a very large extent the
phraseology of Regan, but in which are recognized
a larger number of genera than are admitted by him.
The list of species is accepted with but slight modifica-

& Eigenmann, E. 446.

Habitat: Amazons.

1 Doubtful species of this genus are Citcetostomus
sericeus Cope and Hypostomus erinaceus C. & V.

Kner (1853) described the genus Ancistrus to in-
clude many species, which he divides into the two
groups, Brachypteri, D. I, 7-!, 9, and Macropteri, D. I,
u-I, 13.

Gill (1859) separated the Macropteri under the name
Pterygoplichthys, saying: "The genus Ancistrus seems
to have been framed with special regard to those fishes
to which the name is here restricted, and is by Dr. Kner
divided into tw» sections, which correspond to Ancistrus
and Pterygoplichthys, his section a answering to the
former genus and b to the latter."

The species known to Kner and included in his
Brachypteri are: Hypostomus cirrhosus C. & V, An-
cistrus dolichopterus Kner, Ancistrus gymnorhynchus
Kner, Ancistrus mystacinus Kner, Ancistrus pictus
Kner, Ancistrus brachyurus Kner, Ancistrus scaphirhyn-
chus Kner. There can be no mistake as to what Gill
meant.

Gill redescribed the genus Ancistrus, not to restrict

it, but as he described or redescribed all of the other
genera of fresh-water fishes from Trinidad.

His description of Ancistrus was either drawn from
his specimens of guacharote or from Cuvier & Valen-
cienne's (XV, 508) description of guacharote. Gua-
charote was known to Kner only through C. & V.'s
description and on account " der Ungenauigkeit der
Beschreibung ", he was unable to place it with certainty.
He thought it might be his mystacinus.

Regan considers guacharote as belonging to his new
subgenus Lasiancistrus. But because Gill's wording of
the description applies only to brachyurus and scaphi-
rhynchus (and medians) of Kner, Regan considers the
latter typical of Ancistrus. Gill's diagnosis based on
guacharote, a species not known to Kner and at least
subgenerically distinct from brachyurus and scaphi-
rhynchus, can have no bearing whatever on the restric-
tion of Ancistrus.

Fortunately Bleeker definitely restricted the name to
Kner's first species, cirrhosus.

I am not certain of the position of most of the

from the Atlantic slope unless specifically stated that
they are from the Pacific side.

1 In a recent paper (The Gymnotidae, Proc. Wash.
Acad. Sci., VII, p. 174) I followed Gill in using the
name Gymnotus for the current Gymnotus carapo
Linnaeus, this species being the only one described
by Linnaeus in his tenth edition. No doubt seems to
have been entertained about the nature of the Gymnotus
carapo of Linnaeus and its supposed synonymy and
bibliography were given in the paper quoted above,
P- 175-

Mr. Lonnberg has kindly called my attention to his
paper (Bihang till K. Svenska Vet.-Akad. Handb.,
XXII, Afd. IV, 23, 1896) on Linnean Type-specimens
in which he has shown that the type of Linnaeus is
not the current Gymnotus carapo, but the Gymnotus
fasciatus of Pallas or Giton fasciatus Auct. The latter

Type : Synbranchus marmoratus Bloch.
Range : Tropical America and Indies.
Ai. Synbranchus marmoratus Bloch,

Synbranchus immaculatus Bloch ; S.

species must therefore stand as Gymnotus carapo Lin-
naeus, the name Gymnotus replacing the more recent
Giton.

The current Gymnotus carapus must be known by its
oldest name, which is macrurus Bloch & Schneider.
Miiller & Troschel in 1849 proposed the name Sterno-
pygus for macrurus, tumifrons, virescens, lineatus, and
aquilabiatus. In 1894 I selected as the type of Sterno-
pygus the then current carapo, of which macrurus was
a synonym. The fact that the name carapo of Linnaeus
did not refer to the species under consideration need
not invalidate this restriction, since there was no doubt
whatever about the fish that was intended to serve as
type. It may stand as Sternopygus macrurus (Bloch &
Schneider) .

Inasmuch as the species described by Heckel in-
cluded members of four distinct genera and since he
added members of three other genera from species
known to him from descriptions, we cannot say that he
had any very definite thing in mind when he framed
the genus.

In the generic description he refers to figures of the
lower pharyngeals and gill-arches of Acara tetramerus
and crassispinis.

As far as Heckel's work is concerned, his Acara,
containing the type of Swainson's Astronotus (to the
figure of which Heckel definitely refers in his generic
description) might be a synonym of Astronotus or
separate from it, depending altogether on which of his
species, if any, he considered his type. If any presump-
tion is permitted, it must be in favor of his first species
or the last, or one of the species whose figures are
referred to in his generic description. The first species
is a synonym of Sci&na bimaculata Linnaeus and be-
longs to the genus Cichlasoma of Swainson. If the
first species is selected, the name Acara becomes a syn-
onym of Cichlasoma. If the last species, crassispinis,
is selected, Acara becomes a synonym of Astronotus,

Heckel; Chromys punctata and uni-
ocellata Castelnau.

Habitat : Essequibo ; Amazons south to
Rio Janeiro and Paraguay.

since crassispinis is a synonym of ocellatus, the type of
the latter genus. If one of the two species figured is
selected we may have tetramerus or again crassispinis
as the type for Acara. If the former is selected the
name Acara will stand.

Inasmuch as Heckel does not select a type, it is
incumbent on a later naturalist to select a type from
among the four species discussed, or from among any
of Heckel's species.

In the earliest paper by Gill (Synopsis of the Fresh-
Water Fishes of Trinidad) he says, p. 19: "As it
[Labrus punctatus, the type of Cichlasoma'] is a true
Acara, the latter genus is consequently synonymous with
Cychlasoma, and in accordance with the law of priority,
the Swainsonian name must be adopted as that of the
present genus." Gill re-defines the genus Cichlasoma,
excluding several of Heckel's species, and continues:
" With these characters, that species which Mr. Heckel
. . . has described as the Acara crassispinis, will also
be excluded [from the genus Cichlasoma'] ; this species
appears to be generically distinct from both Cychlasoma
and from Astronotus of Swainson. ... If it should be
found, on a more critical examination, to be really
distinct from Astronotus, to which it is most nearly
allied, Heckel's name of Acara might appropriately be
retained as its generic name. ... It belongs to the
section E of the genus Acara, in the arrangement of
Heckel . . . ; the other sections ... all belong to
Cychlasoma as now restricted."

Gill thus removed from Acara all of Heckel's species
but crassispinis.

There can be no question that it was entirely within
the province of Gill to restrict the genus to this species.
But it was found later that crassispinis is a synonym of
ocellatus, the type of Astronotus. Acara is therefore
the exact synonym of Astronotus and cannot be used for
anything else. Inasmuch as tetramerus and other spe-
cies are distinct from Astronotus, I coined the name
/Equidens for them in 1894. (Ann. N. Y. Acad. Sci.,
VII, 616, using the Acara tetramerus Heckel as type.)

The name Acara has been resurrected by Regan (Ann.
and Mag. Nat. Hist. (7), XV, 1905, p. 330), who says:
" After removing from Heckel's genus the species
which belong to Astronotus, Cichlasoma and Acaropsis,
I use Acara for the remainder, regarding Gill's restric-
tion of the name Acara to a species which was already
the type of another genus as invalid."

I know of no rule, ancient or modern, of scientific
nomenclature which authorizes anyone to regard as
invalid the work done by someone else, unless that work
was done contrary to the accepted canons. In fact, the
rules (if I am not mistaken) have been made especially
to prevent this sort of procedure.

NON-MARINE MOLLUSCA OF PATAGONIA.

BY

HENRY A. PILSBRY,
ACADEMY OF NATURAL SCIENCES, PHILADELPHIA.

This report deals with the non-marine mollusks of Tierra del Fuego
and Patagonia as far north as the thirty-ninth parallel, where the Rio
Negro Valley forms a transition region, the Patagonian fauna giving place
to the La Platan.

The scope of the work has been extended to include some account of
all the South American forms of certain little-known families, such as the
AmmcoBda and Spliczriidce, and all of the Chilinida occurring east of the
Andes. Finally, the relationships of the South American molluscan fauna
with the faunas of other continents are considered.

The collections made by Mr. J. B. Hatcher and placed in my hands by
Professor William B. Scott form the basis of this report. The material
from the region along the Rio Chico de la Santa Cruz and in the base of
the Andes above its head is ample. Elsewhere but few mollusks were
collected, and I have used material which I owe to the generosity of Dr.
H. von Ihering, Director of the Museu Paulista, Dr. W. H. Rush, U.S.N.,
and others.

ZONAL DISTRIBUTION OF PATAGONIAN MOLLUSCA.

An inspection of the data existing on Patagonian mollusks shows that
several faunulas largely distinct in species occupy zones extending from
the Atlantic to the Andes and succeeding one another from north to south.
So far as aquatic animals are concerned, these zones are determined by
the drainage systems, which are separated by poorly wratered plains, and
flow independently into the Atlantic. The aquatic mollusks known from
these several zones are enumerated below.

C/n'liiia, Lymncea and Pisidium are the only genera of fresh-water mol-
lusks which extend throughout Patagonia, the first two also in Tierra del

Fuego. The Unionidce and Mutelidce, groups copiously represented in the
La Plata, have their southern limit in the Rio Negro, each represented by
one species ; Planorbis has two, Ancylus one species, the rest of the fauna
being Patagonian. The Rio Negro fauna, including the region of Bahia
Blanca, is transitional also in land mollusks, the genera Bulimulus, Odon-
tostomus and Strophocheilus reaching their southern limit in the Sierra
Ventana, near Bahia Blanca. In the humid region west of the Cor-
dillera the faunal zones are deflected southward, the transition zone as
marked by the southern limit of Unionidce being in the neighborhood of
Chiloe Island. That the transverse faunal zones of Patagonia run north-
ward in the Andean region is shown by the occurrence on the upper Rio
Chico of several Magellanic forms.

I. LA PLATAN ZoNE.1

Includes the Plata and its tributaries in Argentina, Uruguay, .Paraguay,
Brazil, and rivers flowing into the Atlantic in the Brazilian states of Sao
Paulo and Rio Grande do Sul. Except in Chilinida, only the genera of
this fauna are mentioned below, the species being very numerous.
Chilinidae: Chilina fluminea, C. f. microdon, C. globosa, C. rushii, C. parva,

C. portillensis, C. tehuelcha mendozana.
Physidae : Physa.
Lymnaeidae: Lymncea, Planorbis.
Ancylidae: Ancylus.

Amnicolidae: Littoridina, Potamopyrgus, Potamolithus.
Ampullariidae : Ampullaria, Asolene.
Cyrenidae: Corbicida.
Sphaeriidae : Musfodimn, Pisidium.
Unionidae: Diplodon, Castalia, Castalina.
Mutelidae: Anodontites, Leila, etc.

II. PATAGONIAN ZONE.

A. Rio Negro Patina?

(All of the known aquatic mollusks of this fauna and those following
are enumerated.)

1 Probably the La Platan fauna is a subdivision of the Amazonian, chiefly characterized by the
great development of Chilinidce and Amnicolidez.

Including also the Rio Colorado, and known solely by the works of d'Orbignyand Doering.

PILSBRY: NON-MARINE MOLLUSCA OF PATAGONIA. 515

Chilinidae : Chilina tehuelcha, C. puelcha, C. parchappii.
Lymnaeidae : Lymncea viator, Planorbis peregrinus, P. anatinus.
Ancylidae : Ancylits concentricus bonariensis.
Amnicolidae : Littoridina parchappii, L. australis.
Sphaeriidae : Not reported, but doubtless present.
Union idae : Diplodon patagonicus.
Mutelidae : Anodontites puelchana.

C. lebnmi, C. perrieri.
Lymnaeidae: Lymncea viator, L. diaphana, L.^d. inelegans, L. patagonica

riochicoensis, L. andeana.

Amnicolidae : Littondina hatcheri, L. simplex, L. sublineata.
Sphaeriidae : Musculium patagonicum, Pisidium magellanicum, P. pata-

gonicum, P. observationis.

D. Magellanic, Fuegian and Falkland Faunas?

Chilinidae : Chilina patagonica, C. amozna, C.fuegiensis, C. monticola, C.

fusca, C. nervosa, C. falklandica.
Lymnaeidae : Lymncea diaphana, L. patagonica, L. pictonica, L. brunneo-

flavida.
Sphaeriidae : Pisidium magellanicum.

These several faunas may be roughly compared with the life-zones of
North America. The La Platan zone is equivalent to the Austral, the Rio
Negro fauna to the Transition, and the remainder of the Patagonian zone
to the Boreal zone of the northern continent.

The distinctness of the Patagonian faunas A, C, D may be attributed
to three main factors : (i) Climate, which imposes limits on the north
or south distribution of species. (2) Absence of streams flowing north or
south, and the consequent isolation of the river systems, favoring the evo-

lution of distinct species. (3) Ignorance of the Patagonian faunas be-
tween the Rio Negro and the Rio Santa Cruz system, and along the base
of the Andes, where Transition forms and intermingling of the species
may occur.

GASTROPODA.

Family ENDODONTIDsE.

Two genera of this family are known from Patagonia : Stephanoda and
Radiodiscus. The relationships of these forms to genera of other regions
are unknown, since we have as yet no knowledge of their soft anatomy.
Endodontidce were present in the North American Carboniferous, repre-
sented by forms resembling the modern Gonyodiscus and Charopa in shell
characters, and like their descendants, living in and upon decaying stumps.
The family is now found all over the world, even on the most remote

islands.

RADIODISCUS Pilsbry.

Radiodiscus Pils., Proc. A. N. S. Phila., 1906, p. 154, for R. milleco status.

Minute, discoidal, openly umbilicate Patuloid snails, with the embryonic
\Y^ whorls minutely engraved spirally, the rest of the shell densely radi-
ally costulate. Aperture rotund-lunate, but slightly oblique, and as high
as wide. Type R. millecostatus Pils. & Ferr.

In the Endodontidce, where small differences in the shell characterize
extensive series of species, it seems desirable to recognize as of generic
rank such readily definable groups as Radiodiscus.

The distribution of this genus is very wide, extending from Tierra del
Fuego to the mountain ranges of the southern boundary of Arizona, where
it meets the Holarctic Gonyodiscus and the Nearctic Helicodiscus, both at
their southern limits. At present, the known distribution of Radiodiscus
is markedly discontinuous, one area extending from southern Arizona to
central Mexico, the other from southern Brazil to Cape Horn ; yet it must
be remembered that the Andes and northern South America are un-
searched for minute shells. We know very few so small as these (2 to
3 mm. diam.); and some of the species imperfectly described may turn
out to belong to Radiodiscus. It is likely that the group is an Austral
one, which has invaded Mexico from the south.

Some Tasmanian snails have a great resemblance to Radiodiscus, in

size, form and sculpture — a resemblance possibly due to convergence, but
perhaps indicating affinity. I have not been able to actually compare
specimens. On account of their spirally sculptured embryonic shells
Hedley has referred them to the subgenus Allodiscus of the genus Flam-
mulina. J

RADIODISCUS COPPINGERI (E. A. Smith).

Helix (Patuld] coppingeri Smith, P. Z. S., 1881, p. 36, pi. 4, f. 14, 140.
Patula coppingeri Smith, Strebel, Zool. Jahrb., XXV, 1907, p. 159.

The shell is described as i X i# mm., composed of y/2 whorls, the
" umbilicus moderately small, equalling about one-sixth of the basal
diameter."

It was described from Tom Bay (Dr. Coppinger), found on a rotten
tree. This is near Madre de Dios Island, on the west coast. Strebel
reports specimens which he identified as coppingeri from the west coast
of Tierra del Fuego, Ushuaia, and Navarin Island. While this form must
stand near R. patagonicus, it appears distinct by the much smaller um-
bilicus, if we may trust the published figures. I have not seen specimens.
The apical sculpture has not been described.

The above description and the figures are from a shell collected alive
50 miles above the Sierra Oveja. The original description, in Portuguese,
was based upon fossil specimens, which had lost the color and part of the
finer sculpture. The original lot of patagonicus was from Santa Cruz, on
the coast, in a modern deposit. Part of the original lot is before me.
They are a little larger than the living shell described, with the whorls
slightly deeper ; yet in the series examined from all of the localities yet
known, the very slight differences seem to intergrade.

STEPHANODA Albers.

This group comprises Patuloid species in which the embryonic whorl is
typically smooth, but in some forms now referred here it is marked with
radial striae, but no spirals. It differs from Amphidoxa (with which I
formerly united it) by the more numerous, less rapidly widening whorls.
Without a knowledge of the soft parts, the relationships of these South
American snails to the Austral Charopa and Flammulina, and to the northern
Patuliform genera, cannot be defined. The following species from southern
Patagonia belong here :
S. lyrata (Gld.), summit of highest mountain near Orange Harbor, etc.

(Helix lyrata Gld.).

S. leptotera (Mab. et Rochebr.), Orange Bay (Patula leptotera M. & R.).
S. rigophila (Mab. et Rochebr.), Orange Bay (Patula r., M. & R.).

Family ZONITIDsE.

The small land snails originally described as Helix saxatilis Gld. and
H. ordinaria Smith have all the external characters of the Hyalinia group
of Zonitidce. H. saxatilis has pedal grooves and a mucous pore at the
tail. Mabille and Rochebrune have proposed for it the generic term
Payenia. What status this group will ultimately be given depends wholly
upon the internal anatomy, of which we know nothing. It may possibly
belong to the Endodontidce.

Dr. Doering's description and figures apply fairly well to a Succinea of
the S. avara group, which is abundant and widely distributed in the ter-

Specimens from a spring 7 miles above the Sierra Ventana, "on horse

from honey-yellow to whitish-yellow, always with the first whorl of a
deeper yellow shade. The suture is very deep and the whorls extremely
convex. The specimens figured measure :

It will be noted that, as compared with Doering's description, these shells
have the aperture shorter.

At all other stations the shells are smaller. Two figured from the Rio

LYMN^A Lamarck.

Lymncea is more widely distributed than any other genus of freshwater
mollusks, extending from the shores of the Arctic Ocean to Tasmania and
Cape Horn, and in the Pacific reaching the Hawaiian group. The genus
in its present limits is a synthetic group, which no doubt will ultimately
be divided into several genera.

There are very few species in tropical South America, where the genus
seems to be of rare occurrence ; but in Patagonia the species are more
numerous, individuals are abundant and generally distributed. South
American Lymnaeas fall into three subgenera or sections of the genus.
Section I is clearly an intrusive element from North America. Sec-
tion II may possibly be of North American origin, but its relationships
are unknown, as no specimens with the soft parts have been received.
Section III is peculiar to Patagonia, and not closely related to any nor-
thern forms.

I. Section GALBA Schrank. The marginal teeth of the radula differ
from the laterals by being more oblique, but are essentially tr^ispid. The
shell is small, compactly coiled, of very convex whorls, usually umbilicate,
the columellar lip broadly revolute, not folded. The type is L. truncafala
of Europe. South America species, L. viator, L. cousini.

II. Section ? Dentition unknown. The shell is lengthened,

fragile, Succmea-shaped, of few whorls, the last large and elliptical. L.
peregrina, L. andeana.

III. Section PECTINIDENS n. sect. The marginal teeth are broad and
short, the cusps split into a comb-like series of many narrow denticles.
Type Lymncea diaphana King. There are two groups of species.

Group of L. diaphana. Moderately large, elongated forms, with very
convex whorls and a narrow umbilical chink.

Group of L. patagonica. Small forms, with very short spire (peculiarly
liable to truncation) and few whorls, the last relatively very large and
short, rimate or imperforate. L. patagonica, L. p. riochicoensis, L. pic-

tonica. It is possible that the presence of acid in the water, causing erosion
of the shell, may also account for the stunted stature of these forms.

DENTITION OF SOUTH AMERICAN LYMN^EAS.

Dentition of L. viator d'Orb. — The radula examined was from one of
the specimens taken on the Rio Chico near the Sierra Oveja. The central
tooth is narrow and unicuspid as usual. There are three or four lateral
teeth, having two long cusps. In the following transition teeth the inner
cusp (entocone + mesocone) is long and bifid, ectocone simple. The

marginal teeth are very oblique, with three cusps, entocone, mesocone and
ectocone. In some of the outer marginal teeth there may be one or two
minute accessory cusps.

The radula of L. viator agrees well with that of the European L. trun-
catula as figured by Lehmann. It differs from typical Lymncea by retain-
ing the primitive tricuspid type of teeth in the marginal series, with few
small accessory cusps or none. Lymnaeas with this type of teeth have a
continuous distribution from Patagonia to Alaska and in the Palaearctic
region.

Dentition of Lymncea diaphana King. — These are about 30, 7, I, 7,
30 teeth. The central tooth is wider than usual in Lymneea, unicuspid.
The lateral teeth are bicuspid, the broad inner cusp becoming bifid on
the transition teeth. The inner marginals have the mesocone and ento-

parallel to the long axis of the tooth, and are split into a comb-like series
of denticles.

The marginal teeth of L. diaphana differ from those of typical Lymncea
by their prostrate position, the cusp of one tooth overlying the basal plate
of the succeeding one in the same transverse row, and also by the comb-
like cusps. In typical Lymncea (L. stagnalis, fig. 3) the cusp stands
obliquely erect, its cutting edge transverse to the long axis of the tooth.

Lymncea patagonica riochicoensis (fig. 4, two outer lateral and two inner
marginal teeth) has a radula closely resembling that of L. diaphana.
There are ten lateral teeth.

No Lymncea of the northern hemisphere, of which the teeth are known,
has marginals like those of L. diaphana, but I have shown that some-
what similar teeth exist in a Hawaiian species.1

Limnaus viator d'Orb., Magazin de Zoologie, 1835, p. 24; Voy. dans
1'Amer. Merid., Moll., p. 340, pi. 43, figs. 1-3.

A species of the group of L. truncatula. The shell is small and
smoothish, composed of five very convex whorls, joined by a very deep
suture ; the aperture is oval or nearly round, more than half the length of
the shell. The axis is very distinctly umbilicate. Length 8, diam. 4 mm.

d'Orbigny records this species from the banks of the Rio Negro, 41° S.
lat, 7 or 8 leagues above the mouth, very abundant. This may be con-
sidered the type locality. Afterwards he collected it also at Santiago,
Chili, and at Callao and Lima, Peru, in irrigation ditches. The speci-
mens from Peru, he notes, are constantly more elongate than those of
Patagonia and Chili, with the whorls more deeply separated. Dr. W. H.
Rush collected many specimens in a creek in the Prado, at Montevideo,
Uruguay. These specimens, with others from Lima before me, do not
seem separable from the Antillean L. ctibensis Pfr. (1840) by any character
in the shells.

Specimens from a pool on the bank of the Rio Chico, a mile west of
the Sierra Oveja (PI. XLVI, fig. 8) are larger than those from Uruguay,
the individual figured measuring length 10, diam. 5.1, length of aperture
5 mm., whorls 5^. The spire is longer, and the umbilicus somewhat
narrower. The columellar margin is broadly revolute and without fold
or perceptible sinuosity. This form differs from that figured by d'Orbigny,
and from the Montevideo shells examined, chiefly by having a longer spire
and shorter aperture, the latter half as long as the shell ; by having more
whorls, a smaller umbilicus, and by its somewhat greater size.

King's type measured about 17 X 7.5 mm. ; Strebel's shells were smaller,
10-13 mm. long, and he seems to have entertained some doubt of their
identity with King's. L. lebruni is described as 16 to 20 mm. long, and
agrees well with L. diaphana in other respects. It may be noted that
Mabille and Rochebrune do not mention L. diaphana, and evidently
overlooked it.

On the Rio Chico de la Santa Cruz Mr. Hatcher collected numerous
Lymnaeas of the L. diaphana type, some agreeing with the typical form
from the Straits of Magellan, others divergent therefrom.

In what I take to be typical L. diaphana, from a spring on the Rio
Chico, 15 miles above the Sierra Oveja (PI. XLVI, figs. 3, 7, 9) the
shell is thin, but moderately strong, narrowly rimate, rather long, the last
whorl swollen, but much smaller than in L. d. inelegans, very evenly
rounded, with sculpture of unequal growth-lines, but not malleated, and
very glossy. The spire is long, slender and acuminate. The shortly
ovate aperture is rather small ; columella very narrowly revolute, not
adnate above, continuing free to the parietal wall above the axial crevice.
The color is light brown, or, when the cuticle is worn off, pink, or pinkish
white. Specimens measure :

The specimens from the second locality mentioned are more regular in
contour. Up to a length of 15^ to 16 mm. the surface shows no mallea-
tion, and at that size the shells of this lot reach maturity. The lip
expands slightly and a very thin, white, submarginal callus strengthens it.
In one individual growth has proceeded beyond this stage, the part added
being strongly malleated. This shell (PI. XLVI, fig. 5) measures, length
17, diam. 10, length of aperture 9.8 mm.; whorls 5.

In two of the four lots from "springs on the Rio Chico, 25 miles above
Sierra Oveja," there are some dwarf individuals. One measures, length
10, diam. 6, aperture 6.5 mm.; whorls 4%. In another lot, all the shells
are similarly dwarfed.

In the Rio Chico, 50 miles above Sierra Oveja, a similar dwarf shell
was taken.

and more or less malleation. One measures, length 14, diam. 8, length
of aperture 8.6 mm.; whorls 45^. Those from the Arroyo Eke, near the
head of Spring Creek, are also small.

In Swan Lake (about 50 miles north of the Rio Chico) the shells are
very delicate, almost like tissue paper, but little malleated or (usually)
without malleation, and of a pale olive color. Most of the examples con-
form nearly to PI. XLVItf, fig. 2, in shape, but I have also figured the most
elongate (fig. i) and the shortest (fig. 3) shells. Fig. 2 measures, length
19, diam. n, length of aperture 10.9 mm.; whorls 4^4.

Mr. Hatcher in his narrative has alluded to the abundance of shells in
this lake (Reports of the Princeton University Expeditions to Patagonia,
I, p. 166). The lake basin is composed of igneous rocks dammed by a
lava flow. To the absence of calcareous material, the tenuity of the shells
is probably due.

Lymncea brunneoflavida Preston, Annals and Magazine of Natural His-

an entire specimen (fig. n) there are 3% convex and rapidly enlarging
whorls, the last inconspicuously marked with rather widely spaced, very
low longitudinal wrinkles, and some weak malleation in places. The
aperture appears to be less rounded than in L. patagonica. The parietal
and axial callus is a mere transparent film (not distinct as shown in fig.
1 1 ), closely adnate throughout. The columella is white, solid and rounded,
nearly straight, and without trace of a fold. The largest specimen (fig.

Oveja, one characteristic individual.

Most of the adult examples taken are very much eroded, the spire re-
moved, and the last whorl deeply eaten in places, as though by acid.
The parietal callus is thick, with the outer edge distinctly raised. The
external erosion is compensated by thickening of the shell from the inside.
Fig. 10 measures:

Length 5, diam. 4, aperture 4.1 X 3 mm.; 2*4 whorls.

Although the perfect and the deeply eroded shells were in one lot when
received, yet I have no doubt that they came from two sources, one of pure
water, the other carrying CO2, doubtless from leaching through decaying
organic matter.

400 to 500 miles farther north, by L. p. riochicoensis. It is quite possible,
however, that these several forms may prove to be independent shortened
forms, each directly related to more normal forms.

SECTION UNDETERMINED.
LYMN^EA ANDEANA sp. nov.

(Plate XLVI0, Figs. 4, 40.)

The shell is acuminate-oblong, imperforate, very thin and fragile, pale
yellowish-corneous, translucent. Surface dull, smooth to the eye except
on the last part of the last whorl, where it is conspicuously malleated.
Under the microscope the dullness is seen to be caused by extremely fine
hair-lines, mainly longitudinal in direction, but forming a close mesh over
the whole surface. There are also faint growth-lines and weak traces of
spiral bands of vertical wrinkles. Whorls barely 4, the first convex, those
following only weakly so. The last whorl has the form of a long ellipse.
Aperture ovate. Parietal film scarcely perceptible. Columella slender,
slightly concave, dilated above, the dilatation thin and adnate.

Length 11.9, diam. 6.3 mm.; aperture 7.3 mm. long.

Near the base of the Andes in drying pools on a high divide, 50 miles
north of the Rio Chico.

This species is apparently related to L. peregrina Clessin of southern
Brazil and Uruguay, but differs conspicuously by the very weak develop-
ment of spiral sculpture, that species being even more copiously striate
spirally than the North American L. colmnella.

A few immature specimens of another thin, fragile species, probably
related to L. andeana, were taken in small streams on the Rio Chico, 10
and 25 miles above the Sierra Oveja.

The apex in Chilina differs from that of all Lymnaeid snails in the initial
half whorl of the embryo, which is tilted up, as shown in fig. 5. Growth
of the shell seems to be upward at first, the nucleus lying below the
summit. At the end of the third whorl, in C. fulgttrata and several other

species, the color-pattern begins weakly. Previous to this the shell is
uniform corneous-brown. The columellar fold is present at a very early
stage, but my material does not show when it first appears.

532 PATAGONIAN EXPEDITIONS I ZOOLOGY.

The growth of the shell in Patagonian species is periodic, growth-arrest
periods being marked by streaks interrupting the normal pattern. On
resumption of growth, the zigzag pattern is sometimes replaced by irregu-
lar streaks ; but in a later growth-period the original pattern may be

resumed.

The subgenus Pseudochilina was based upon a form shaped about like
fig. 7 of Plate XLIII. The irregular or fibrous surface, which served to
characterize the subgenus, seems to me to be wholly due to erosion, the
cuticle or periostracum being lost from the unique type in the National
Museum. In other characters the shell is a typical Chilina.

Acyrogonia of Mabille and Rochebrune is a Chilina in which the colu-
mellar plait is wanting. I have found this plait variable in development
in some forms of Chilina from the Rio Chico. In C. fulgurata oligoptyx
it approaches the condition described in Acyrogonia.

DISTRIBUTION OF CHILINA.

Chilina occupies the temperate and cold zones of South America from
the Tropic of Capricorn to Cape Horn. No member of the group, either
living or fossil, has been found outside of these limits.1 It is noteworthy
that no trace of the group has been found in other Austral lands --Tas-
mania and New Zealand having sufficiently similar climatic conditions to
favor the survival of Chilinidce, if the family ever had a wider range in
the Antarctic area.

Within their area, the Chilinidcz are abundant snails in all suitable sta-
tions, as Physidce are in the north. They swarm in springs, small streams,
lakes, and in some places the margins of rivers. They are most abundant
southward, becoming rarer and local toward the northern borders of their
range.

The species from west of the Andes are in all cases, so far as we know,
distinct from those east of the divide. In the cold temperate and cold
zones at least, the widely diverse physical features on opposite sides of
the Andes would lead us to expect different snail faunas.

^Chilina olivida Repelin, Ann. Mus. d'Hist. Nat. de Marseille, VII, p. 69, of the Cenomanian
of central France, has no columellar fold, and is clearly a Lymnseid snail with no relations what-
ever to Chilina. Chilina in Europe, like Partitla, Polygyra, Glandina, etc., is one of those myths
of European palaeontology which astonish and amuse the investigator using modern methods with
Pulmonate snails.

PILSBRY I NON-MARINE MOLLUSCA OF PATAGONIA. 533

The eastern fauna, with which alone we have now to deal,1 inhabits a
comparatively arid region, poorly watered by roughly parallel streams
flowing southeastward into the Atlantic. Each of the principal river
systems has its own series of freshwater mollusks, in large part distinct
specifically or racially from those of other rivers. The Chilinidce of the sev-
eral drainages have been enumerated on pp. 514-5.

of which to patagonica seems open to doubt.

The specimens figured by Strebel from Gente Grande Bay, under the

of Chilina, and descending to the base of the aperture."

This group is known only by the original account. Neither of the two
species has been figured. I do not think it generically distinct from Chilina.
In some species of that genus the columellar fold is reduced to an incon-
spicuous vestige.

minute, indistinct spiral striae. The ground-color is rather bright yellow
on the last whorl, copiously marked with purplish-brown zigzag streaks,
each with 4 principal angles projecting forward, and more or less
widened at the angles. On the latter part of the whorl the streaks dis-
appear, leaving four bands of spots. The spire is dark blue, with dusky
brown zigzag markings on the penultimate and next earlier whorls, those
above being uniform purplish-brown or dull blue. Whorls between 5^
and 6, convex, regularly increasing, the last elliptical, widest in the middle.
The aperture is nearly vertical, white, rich brown deep in the throat,
showing the external markings as purplish-brown spot-bands. Columella
rather broad, white, bearing a rather stout oblique fold above, a slight
spirally entering prominence below it (in most examples scarcely showing
in front view). Parietal callus thin, bearing a low, spirally entering fold
at its lower third, usually hardly visible in a front view.

Mount of Observation, 40 miles south of Santa Cruz River.

This fine species was collected in some quantity. It is distinguished
from Chilina puelcha d'Orb. by the presence of a parietal fold, among
other peculiarities. No other species from south of the Rio de La Plata drain-
age has this fold developed. In the young stages (figs. 27, 28) the color-
streaks are less distinctly defined, fading at their edges,1 and the parietal
fold is present only as a very thin whitish callus-

CHILINA SMITHI sp. nov.

(Plate XLIII, Figs. 1-4.)

The shell is oblong-ovate, solid, minutely rimate, rather rudely sculp-
tured, with wrinkles of growth and more or less distinct spiral lines ; always
more or less deeply eroded in the adult stage. The color of the cuticle
is olive, or in the newly-formed band behind the outer lip it is yellow. In
adults a large part of the cuticle is wanting, exposing the calcareous layer
beneath, which is blue and gray, or when deeply worn (as in figures 3 and
4), it is white. The spire is worn, whorls convex, the last one distinctly
shoiddered, compressed laterally, widest at the middle or below it. The

aperture is nearly vertical, very dark chestnut-colored within in adults,
less dark in younger shells, fleshy-whitish near the lip-edge, which is thin
and acute. The columella is not very wide, flat, white or flesh-tinted,
more or less concave, and bears a rather small, very oblique fold above.
Parietal callus very thin, transparent.

Springs on the Rio Chico, 15-25 miles above the Sierra Oveja.

This is one of the largest species of the genus, remarkable for its solid,
inornate shell, shouldered at the last whorl (a feature not very well shown
in the figures), and very dark chestnut or purplish-chestnut interior. Typi-
cally the spire is well produced, as in figs, i, 3, but the lot contains also
shortened forms, such as fig. 4.

The shouldered last whorl, solidity and color distinguish this species
from C. parchappii d'Orb. It also attains a larger size. Named in honor
of Mr. E. A. Smith, to whom we owe a very useful catalogue of the genus.

Young shells up to 22 mm. long show faint traces of waved longitudinal
brown streaks on the last whorl, but in older ones these disappear, though
faintly indicated spot-bands may persist up to 30 mm. long in some
examples. Figures 8, 9, 10 of Plate XLIII represent young shells 17.2,
1 6 and 14.5 mm. long respectively. At this stage there are 5^ to 6
whorls. The spire is acuminate and the apex perfect in some individuals.
On a yellow ground there are chestnut streaks, which show three (figs. 8,
9) or four (fig. 10) forwardly projecting angles, with a row of spots just

below the suture.1

CHILINA FULGURATA sp. nov.

(Plates XLIII, Figs. 11-15 ; XLIII*, Fig. 4.)

The shell is imperforate, elliptical, with short, conic spire, thin. Fully
grown shells are in large part dull gray from loss of the cuticle on the
back, but what remains in front is dull pale yellowish, with numerous
dusky brown, angular streaks (fig. 15). Younger shells (fig. 1 1, length 12
mm., and fig. 12, length 13.2 mm.) are densely marked with reddish-chest-
nut, zigzag stripes on a whitish or in places yellow ground, the penultimate
whorl with a blue ground. In an older stage (figs. 13, 14, length 16 mm.)
the ground color on the back and spire is blue, but whitish at the base.
The brown stripes have four forwardly projecting angles. The apices are
more or less eroded in the type lot, but there are evidently not less than
5 whorls. The aperture shows the external marking on a ground more
or less suffused with rich light chestnut in shells not fully adult, but in
old shells the markings are not seen, and the throat becomes chestnut,
fading to whitish near the lip. The columella is rather narrow, white,
straight, or only slightly arcuate, and bears a small and rather thin, very
oblique lamella above.1

Small stream on the Rio Chico, 5 miles above the Sierra Oveja, type
locality ; also northward to the foothills of the Andes, in various springs
and streams.

This species has the elaborate color-pattern of Chilina puelcha
d'Orbigny, but differs from that by its comparatively narrow contour. The
dimensions of the type of C. puelcha are, length 20, diam. 15 mm. C.
fnlgurata is probably related more closely to C. parchappii d'Orb., a
more slender and lengthened species, deficient in color-ornamentation.

The type of C. fnlgurata is drawn in Plate XLIII, figs. 13, 14, and
Plate XLIIIrt, fig. 4.

In springs twenty-five miles above the Sierra Oveja, a large, thin form
of fulgurata was found. The elaborate color-pattern persists through
the period of maturity, but fails in the aged or gerontic stage. The sur-
face has minute axial plicae and distinct spiral lines, giving it a decussate-

granular appearance, more or less developed in different examples. The
columella is flat, vertical, nearly straight, with a small, compressed and
acute fold above. PI. XLIIIa, figs. 6, 6a, represent an"old shell deeply
eroded in places. Length 18 (spire largely eroded), diam. 11, length of
aperture 13 mm. In this lot the cuticle persists over most of the surface.

At 30 miles above the Sierra Oveja similar large shells were found in a
spring. In even the largest, the color-pattern and sculpture persist to
the lip-edge. PI. XLIIIA, fig. 7, represents an area immediately below the
termination of the suture. The shell measures, length 20.7, diam. 11,
length of aperture 13.4 mm. The apex is eroded.

In a small running stream on the south side of the Rio Chico, 25 miles
above Sierra Oveja, two forms of Chilina were found : numerous small C.
fiilgurata, the largest 10 to n mm. long, and probably not fully adult;
and three examples of a very elongate form, one of them figured in PI.
XLIV, fig. 23. In this shell the waved streaks appear only on the last
half of the last whorl, being preceded by two bands of small spots. x The
columella is Lymnaeid. Sculpture as in the large decussate C. fiilgurata.
Axis rimate. Length 17, diam. 8, length of aperture 10 mm. The sig-
nificance of these examples is doubtful.

Small specimens which seem to be C. fulgurata were taken in a spring
on the south side of the Rio Chico, seven miles above the Sierra Ventana.

CHILINA FULGURATA OLIGOPTYX subsp. nov.

(Plate XLIV, Figs. 18, iSa, 20-22^.)

The shell is oval, inflated, with short but acuminate spire of between
5 and 6 whorls. The cuticle is extremely thin and deciduous, but more
or less usually remains on the face and behind the outer lip. It is corneous,
or slightly yellowish (somewhat too yellow in figs. 20, 21, 22), with faint
reddish-brown streaks. Where the epidermis is removed, the shell is ash
colored, or livid purplish or fleshy, sometimes showing traces of the waved
color-markings, the spire often dark purple (as in fig. 22*2). The colu-
mella is only moderately arched, and either has no fold (fig. 18) or a
small fold may be seen above, in an oblique view, sometimes somewhat
stronger than in fig. 22. The outer lip is somewhat thickened within,
in adult shells.

1 The scattered dots shown in fig. 23 are ferrous deposits, foreign to the shell.

By its shorter form, weak or wanting columellar fold, and the less devel-
oped color-pattern, this race differs from C. fulgurata. Some examples
from 25 miles below the Sierra Ventana are more fully colored, resembling
C. fulguvata in this respect ; and it may be said that dead shells which
retain the cuticle also show the color-pattern more distinctly than living

shells.

CHILINA FULGURATA LIVIDA subsp. nov.

(Plates XLIII, Figs. 5-7 ; XLIV, Figs. 16, 17, 19.)

The spire is longer than \n fulgurata, acuminate, and consisting of fully
6X whorls ; spiral strise distinct. In the adult stage the surface, where
unworn, is livid purplish on the back, and color-streaks are wanting or
very weak, though one to three faint spot-bands are generally retained.
The eroded spots have the appearance of mould, the edges under a
hand-lens, appearing fuzzy or fibrous. The columellar fold is usually well
developed, though often appearing weak or blunt in a face view. The
interior is dark purplish-brown.

CHILINA FULGURATA ANDICOLA subsp. nov.

(Plate XLIII«, Figs. 5, 50.)

A series of three quite young shells from under stones along a small
running stream near the mouth of the Rio Belgrano, and a single shell,
perhaps adult, from a spring 50 miles north of the Rio Chico, at an ele-
vation of 1750 ft., indicate that a special race inhabits the Andean foot-
hills, though the material at hand is hardly sufficient for its full charac-
terization. The cuticle is rather bright yellow, with a full development of
the fidgurata pattern in young shells. This pattern begins about the
middle of the third whorl.

In the larger shell (PI. XLIIL?, figs. 5, 5*2), from the second locality, the
ground is olive or greenish-yellow. The first half of the last whorl has
the usual fulgurata streaks, but the last half (following a growth-arrest
period) has the streaks broken, leaving four spot-bands. The yellow
ground also has many fine olive lines. The aperture is like that of
fulgurata. The apex is eroded. Length 8.5, diam. 5, length of aperture
6.8 mm.

CHILINA FULGURATA HATCHERI subsp. nov.

(Plate XLIIIa, Figs. 3, 3«.)

The shell is thin, of a dilute dull red color, variegated with four bands
of spots, more or less indistinct, often hardly noticeable. There are also
some obscure red-brown longitudinal' streaks. The spire is darker,
acuminate above, its surface more or less eroded. There would be over
5 whorls if the apex were perfect. Surface glossy, with fine growth-lines
and very delicate spiral striae, much as in C. f^llg^^rata from 30 miles above
Sierra Oveja, but much more delicate. Columella straight and flattened
below, acutely folded above, similar to large forms of C. fulgurata.

Arroyo Eke, near the headwaters of Spring Creek (north of the Rio
Belgrano), April 10, 1898.

Except on the spire, the cuticle is generally well preserved. When
worn on the last whorl, it is deciduous along the spiral striae, which other-
wise are hardly noticeable. These shells are readily distinguishable from
any taken at lower levels, along the Rio Chico.

CHILINA CAMPYLAXIS sp. nov.

(Plate XLIIIa, Figs. i-2a.)

The shell is oval, much inflated, thin. Dead individuals, but evidently
almost or wholly unchanged in color, are light reddish-brown, with rather
faint streaks of chestnut, which are angular and dilated to form three bands
of sagittiform spots besides a row of small spots below the suture. These
markings are often less fully developed than in the figured specimens, and
they are generally removed in part by the erosion of the surface. Where
the cuticle is retained behind the outer lip, it is yellow. The surface
shows spiral striae more distinct than usual. The aperture is light brown
or fulvous inside. The outer lip does not seem to be thickened within, as
it is in C. f. oligoptyx. The columella is narrow, deeply concave, and has
a small but distinct fold above (rarely subobsolete.)

The numerous specimens vary but slightly in size or other features.
They have some resemblance to the Magellanic C. patagonica, which
however is figured as having a straight columella and a stronger colu-
mellar fold.

All of the specimens are "dead" shells. At this spring C. fulgurata
oligoptyx was also found, both alive and among the dead shells which
were preserved separately ; the larger individuals have the outer lip
noticeably thickened. The shells of C. campylaxis differ constantly from
the associated oligoptyx in various structural features, and must, I think,
be regarded as specifically diverse.

The shell is thin but rather strong, translucent chestnut, with separated,
dilute, waved streaks, or spot bands also, mostly indistinct ; comparatively
broad, with short, acute spire of about 5 whorls. Columella has a very
weak fold, not visible in front view.

Strebel seems to entertain some doubt as to whether this may not be
an immature stage of C. ovalis Sowerby. I have not seen specimens.

CHILINA MONTICOLA PILULA subsp. nov.

(Plate XLIV, Figs. 29, 30, 300.)

The shell is very small, shortly oval, with a very short conic spire ;
thin ; glossy when unworn, sculptured with fine growth-striae and indis-
tinct, minute spiral lines. Adult shells are generally dull ashy- or brown-
ish-white from loss of the cuticle, but where preserved, it is yellow or
dusky reddish, closely marked with indistinct reddish-brown streaks, upon
which there are spots at intervals, forming five spiral bands, one just
below the suture, the others at subequal intervals on the last whorl. The
longitudinal streaks are scarcely visible on some examples, and the spot-
bands are often very faint or reduced to three. The very short spire is eroded
in all the specimens seen, the number of whorls being therefore uncer-
tain. The aperture is quite ample and shows the external color through
the thin outer lip. The columella is white, rather narrow and weakly

hardly noticeable in most specimens.

Springs on the Rio Chico, 25 miles below the Sierra Ventana, Feb. 15,

1899-

This species is known from 40 specimens in two lots, taken the same
day in the same neighborhood, but apparently from two springs, the sta-
tion numbers being different and the condition of the specimens as
regards erosion slightly diverse. There is also another individual from a
different station, "freshwater spring on the Rio Chico," date and locality
not given. They range in size from young shells less than 3 mm. long
to slightly over 5 mm. In a shell of 3 mm. there are fully three whorls.
All the adults have the spire worn, so that the number of whorls is un-
certain, but there are evidently four or more.

The very globose shape of these shells shows that they are not young
or dwarf individuals of the larger species of the same region. Moreover,
the larger ones have the eroded and old appearance of adult snails.
Whether the species attains greater size in the streams running from the
springs which they inhabit remains uncertain. I know of several instances
of dwarf snails inhabiting springs, having put at least one such case on
record.1 It is evident that the usual explanations of dwarfing in small
quantities of water are not pertinent, since in flowing springs there is no
lack of aeration and no accumulation of the toxines of metabolism. It
seems likely that the dwarfing of snails in springs may be due to the
purity of the water, which affords an insufficient supply of diatoms, other
algae and vegetable food.

This form is, for the time being, ranked as a subspecies of Chilina monti-
cola from Punta Arenas, but I suspect that it is related rather to C. ftilgu-
rata. Apparently adult shells are only about half the size of monticola.

A short-oval, inflated shell, with usually olive ground-color, but some-
times olive-yellow or bright green, and either unicolored or marked with
one to five spiral bands of dark chestnut spots, alternating with spots paler
than the ground-color. The upper bands are more persistent than those
below. Very rarely the pattern is of irregularly zigzag streaks flowing
from the suture down, not quite reaching the base (fig. 38). The ample
aperture is blue-white within, and usually shows the external markings
through. The columellar lamella is very strong, and a long entering callous
ridge stands on the parietal wall, and is always well developed in adult
snails. The specimens figured from San Gabriel's Island, opposite
Colonia, Uruguay, measure :

of this race, which inhabits the Jacuhy river system.

As in C. fluminea, there is wide variation in the size and prominence of

much more produced, figs. 42, 43. The tip of the spire is worn away in

According to Frauenfeld, this is a round-oval, brownish yellow shell,
with three hardly noticeable spot-bands on the last whorl. Columellar lip
very thick, covered with a white callus to the upper end, two-toothed.

angle, which crowns the last whorl. It is also stained with iron oxide in
front and under the parietal callus. The very heavy columellar callus
continues upon the parietal wall, bearing thick, obtuse, parietal and colu-
mellar lamellae.

This species is chiefly distinguished from C. fluminea by its very heavy
parietal callus.

This family of minute river-snails has been but little studied or col-
lected in South America. We have some knowledge of the species of
the Rio de La Plata system though the work of d'Orbigny, Doering and
Strobel and collections made by Dr. W. H. Rush, U.S.N. In south-
ern Brazil Dr. von Ihering has done good work, though hampered by
the want of La Platan material for comparison. In Ecuador K. Miller
has described a few forms collected by Wolf and others. In the north,
Dr. von Martens has recorded a few Venezuelan species. None are
known from the Orinoco or Amazon systems. Through the collections of
Mr. Hatcher we are now enabled to add several forms from Patagonia.
The opportunity has also been taken fully to describe and figure the
known species of Potamolithus, part of them new forms, most of the rest
hitherto defined only by a brief "key" published in 1892. Only six of
the thirty species now known have hitherto been figured.

All of the South American genera and species of Amnicolidce are de-
scribed or referred to below.

The following genera of this family are represented in South America :

Amnicola Gould and Haldeman, Idiopyrgus Pilsbry,
Littoridina Souleyet, Potamolitkus Pilsbry,

Potamopyrgus Stimpson, Lithococcus Pilsbry.

Of these genera, Amnicola has been found only in the extreme north.
A. ernesti (Martens) of Lake Valencia, Venezuela, is closely related to
A. panamensis Tryon and several Mexican species, and is undoubtedly
of North American origin. *

Potamopyrgus is the dominant genus of Amnicolidce in New Zealand
and Tasmania. It is unknown in the Oriental region. In America it
extends from Argentina to Venezuela, through Mexico to central Texas
and throughout the West Indies. This distribution is explicable on the

supposition that the genus had its origin in Antarctica, or one of the
Austral lands once connected therewith.

Littoridina resembles the Holarctic Pahidestrina and the genus Flumo-
pitpa * of Australia and the Melanesian Plateau, but until the external
genitalia of all can be compared, no well-founded opinion of the affinities
of these genera can be formed.

Idiopyrgns is an Archhelenic genus, if my estimate of its affinities is
correct.

The affinities fAIMkococcus are uncertain.

Potamolithus, in the form of the shell, closely resembles the genera
assembled by Tryon in the subfamily Lithoglyphina : Fluminicola of
western North America, Lithoglyphus of eastern Europe, Pachydrobia,
Lacunopsis and Julliema of Indo-China. All of these genera differ from
Potamolitlins by the small number and large size of the cusps of the outer
marginal teeth.2 Fluminicola has male genitalia of widely different form.

550 PATAGONIAN EXPEDITIONS: ZOOLOGY.

radula resembles that of Potamolithus in the important character of having
many minute cusps on the marginal teeth, more than double the number
of those on the admedian tooth. It differs from Potamolithus by having
a single basal cusp or denticle on each side of the central tooth, Potamo-
lithus having two or more. I have found the number of basal cusps so
variable in many genera that I do not attach much importance to this
character. Of all known genera, Petterdiana is, in my opinion, the most
closely related to Potamolittms.

Marginal teeth with a small number of cusps characterize the subfamily
IMhoglyphina. The Austral genera Potamolithus and Petterdiana cannot
be included in this subfamily. They may for the present be placed in the
Amnicolince.

but slightly convex, rarely carinate ; aperture ovate, not very oblique, less
than half as long as the shell ; peristome thin and simple, continuous or
interrupted. The operculum is thin, ovate, paucispiral, the nucleus below
the lower third and near the columellar margin. The long penis has
several digitate lateral papillae or simple warts, and is curved at the end.
The central tooth of the radula has one to four basal denticles on each
side. The marginal teeth have very numerous denticles, more than twice
as many as the admedian tooth. The animal is oviparous.

DENTITION OF LITTORIDINA.

Littoridina guadichaudii, the type of the genus, has several, probably
four, basal denticles on each side of the central tooth. Souleyet's figure
shows five, but allowance must be made for the difficulty of the object and
the date, 1852.

Dr. von Ihering found two basal denticles on each side in L. australis.

a shell resembling Paludestrina or Bythinella, but differing by the penis,
which is not bifid, and has several lateral papillae or warts.

We owe to Souleyet an excellent account of the anatomy of L. guadi-
chaudii, and Dr. von Ihering has published valuable notes on that of
several species of southern Brazil. Many other species are referred to
Littoridina from the resemblance of the shells and their distribution alone.
Most of them have been described under genera based upon European
types, such as Paludestrina and Hydrobia, which, so far as we know, differ
anatomically from the type of Littoridina. Provisionally, therefore, we
refer to Littoridina all of the smooth, slender and thin oviparous Amni-
colinae of South America, having the lip simple.

Most of the species are fresh-water forms, but a few live as well in the
brackish water of estuaries, or even in the salt water of sheltered bays.
They are known to extend from below the mouth of Santa Cruz River in
Patagonia north to Ecuador in the west, and to the state of Rio Janeiro,
Brazil, in the east.

Many species of Littoridina have been described from the La Plata sys-
tem and the Sierras of western Argentina (Provinces of Cordoba and Men-
doza) by d'Orbigny,1 Strobel2 and Doering,3 but none have heretofore been
reported from the southern territories. Mr. Hatcher's collections extend
the range of the genus south to the Mount of Observation, below the
mouth of the Santa Cruz River.

Several species of Littoridina have both slender and stouter forms,
with others of intermediate shape, in any large lot. These differences
may be sexual, but no observations bearing on the point have been made.
In some other species the contour is nearly uniform.

Various authors having referred the Littoridinas to d'Orbigny's Palu-
destrina, it may be well to give some account of that genus.

Paludestrina was proposed by A. d'Orbigny in i8394 f°r Paludina
acuta of France and the South American rissoids of fresh and brackish
water, having the operculum spiral, such as P. lapidum, P. peristomata and
P. australis. Various subsequent authors have mentioned or discussed

the group, but no type species seems to have been selected until William
Stimpson, in 1865, selected P. auberiana d'Orb. as type.1 Bourguignat
in January, 1887, named P. acuta Drap. as type of the genus.2 In 1895
Dr. von Ihering proposed to restrict Paludestrina to the group now called
Potamolithus, with P. peristomata as type.3 This course cannot be fol-
lowed because of Bourguignat's earlier selection. P. acuta (Drap.) must
stand as the type of Paludestrina.

The following names will fall as synonyms of Paludestrina : Littori-
nella Braun, 1846, type L. acuta (Drap.). Ecrobia Stimpson, 1865, type
Turbo minutus Totten. The preceding live in brackish water, or in
sheltered bays or estuaries, or sometimes where the water is fresh.
The exclusively fresh- water groups Bythinella Moq., 1851, type B. mridis
Moq., and Stimpsonia Clessin, i8y8,4 type B. nickliniana (Lea), are in-
distinguishable from Paludestrina in shell, operculum and dentition, but
according to Moquin-Tandon the penis of B. ferrusma is bifid, while
that of P. minuta (Totten) was found to be simple by Stimpson. Until
the types of these proposed genera are studied and the forms of their
penes ascertained, there seems to be little reason for recognizing more
than one genus of these slender Amnicoloid snails in North America and
Europe, although it is likely that several may ultimately be defined.

In Paludestrina (including Bythinella] the central tooth has a single
well-developed basal denticle on each side, but often a second one is
weakly developed.

The shell is minute, imperforate (though slightly rimate), rather solid,
olivaceous brown, smooth ; in shape ovate or somewhat pupiform. The
outlines of the spire are convex ; the summit minute, a little obtuse,
though the apex is not depressed. Whorls 4, convex, at first slowly, then
rapidly widening, the suture therefore descends more rapidly and
obliquely in its last volution, and it is also deeper than in those preceding.

This selection was not valid for the reason that auberiana was not one of the species included
in Paludestrina in d'Orbigny's original publication, but was added some years later.

The last whorl is rounded and expands towards the aperture, at the upper
angle of which it descends slightly. The aperture is subvertical, sym-
metrically ovate, narrower but not angular above. The peristome is con-
tinuous, of a deep reddish brown color, almost black at the edge. The
outer margin is slightly thickened and obtuse ; the inner margin is rather
heavily calloused, forming a raised ledge across the preceding whorl,

This small snail is evidently abundant in springs and small streams
along the whole course of the Rio Chico de la Sta. Cruz. It is apparently
related to L. kuesteri and especially to L. k. cordillercz (Strobel),1 from the
Province of Mendoza, but differs from these by its wider, convexly conic
spire, the shape of L. hatcJieri being rather pupiform, whereas the spire is
strictly conic in L. kuesteri and cordillerce.

L. hatcheri varies within wide limits in nearly all of the colonies col-
lected. This variation is chiefly ( i ) in size, nearly every lot consisting of
both large and small individuals, the difference being greater than I have
ever observed in North American Amnicolidce ; and (2) in the degree
of descent, lateral deviation or uncoiling of the last whorl. As type I
have selected a shell nearly normal in shape, PI. XLII, figs. 7, ja, 2.25

mm. long. Some others in the same lot are smaller and more pupiform,
with the parietal callus barely free from the preceding whorl, as in fig. 8,
length 1.7 mm. The entire lot from the type locality consists of shells
which do not depart much from the normal Littoridina contour.

At two stations, 40 and 50 miles above the Sierra Oveja, a considerable
proportion of the shells have the last whorl deeply descending to the aper-
ture and becoming free, or partially free near the termination. A series
from 40 miles above Sierra Oveja is figured, PI. XLII, figs, n, na, 12,
13. Fig. 12 represents a nearly normal shell; figs, n, na and 13,
those with the last whorl loosening its coil ; all are fully mature, but not
old snails. The individuals figured measure :

" 13. " 2.1 " 1.3 " " i " "

The same tendency is well-marked in a lot from far down the river,
below the mouth of the Rio Chalia. The other lots of the species resemble
the type lot, having the shape nearly normal, but with a variable proportion
of individuals in which the peristome is partly or for a short distance free.

L. hatchen is thus a species distinctly aged or gerontic, with this feature
much more strongly emphasized in certain colonies.

LITTORIDINA SIMPLEX sp. nov.

(Plate XLII, Figs. 9, 10.)

The shell is minutely rimate but scarcely perforate, rather thin, ovate-
conic, of a very pale olivaceous-yellowish tint, the apex and first whorl
reddish in the type lot, smoothish, but lightly marked with growth-lines.
The spire is straightly conic, the apex minute and very slightly obtuse.
Whorls 4^ , all rather strongly convex, regularly enlarging, and joined
by an impressed suture, which on the last whorl or two shows a narrow
faint margination below caused by transparence. The aperture is ovate,
subvertical. Peristome continuous, its edge delicately marked with a
brownish line. The outer lip curves forward a little in the middle, and
has a very delicate whitish thickening within. Inner margin thickened a
little, continuous, in contact with the preceding whorl.

556 PATAGONIAN EXPEDITIONS I ZOOLOGY.

Springs along the Rio Chico de la Sta. Cruz, at the following places :
About 15-20 miles above the mouth of the Rio Chalia; springs 20 and
25 miles below the Sierra Ventana ; spring near the Sierra Ventana (type
locality) ; 25 and 50 miles above the Sierra Oveja. Also near Mt. of
Observation, on the coast, below the mouth of the Santa Cruz River.
Also at the foot of the Andes, 50 miles north of the Rio Chico.

This species resembles several forms of the Rio de La Plata system, but
is distinguished by the combination of quite strongly convex whorls and
a continuous peristome ; its inner margin, though not much thickened, yet
forms a distinct ledge across the preceding whorl. The striation is exag-
gerated in fig. 9, and the umbilical chink is represented too wide and
prominent in both figures. The apex is reddish in the type lot, but not
in others. L. simplex occurs in the same springs with L. hatcheri along
the Rio Chico, but it is apparently less abundant and it does not seem to
ascend the river so far.

LlTTORIDINA SUBLINEATA Sp. nOV.
(Plate XLVItf, Figs. 5, $«.)

The shell is imperforate, ovate-pyramidal, thin, light brown. Surface
faintly marked with growth-lines, and on the last half of the last whorl
there are several (four or five in the type specimen) very low spiral cords,
grouped in the peripheral region. The spire is rather straightly conic,
the summit a little obtuse, the apex rising but little above the level of the
first whorl. Whorls 5, convex, the last very indistinctly angular below
the periphery, causing the base to appear slightly flattened. The aperture
is ovate, very slightly oblique; peristome thin and acute, the outer margin
not darkened or thickened. Columella concave, slightly thickened, con-
tinued in a thin adnate callus across the parietal wall.

Length 3.6, diam. 2.2 mm., length of aperture 1.5 mm.

Small stream on the Rio Chico, 35 miles above the Sierra Oveja (type
locality) ; also in a spring 25 miles above the Sierra Oveja, and in a "big
spring on the Rio Chico," the exact location of which was not noted on
the collector's label.

It sometimes attains a larger size than the type, a shell from the second
lot noted above being 5.4 mm. long with 5^ whorls. This species differs
from L. simplex by its weakly subangular periphery, marked with a few
spiral lines, the less prominent parietal callus and fragile outer lip.

d'Orbigny gives the dimensions, length 6, diam. 3 mm., whorls 7. Fig.
7, drawn from a specimen from Bahia Blanca, the type locality, is of this
size. Some examples are narrower (fig. 6), and others much larger, length
8.5 mm. (fig. 5). The whorls are almost flat except in the largest shells,
where the last whorl is convex. Under a strong lens very faint spiral
striae may be seen on most examples. Figures 5-7 represent bleached
shells from Bahia Blanca, the type locality, received from Dr. von
Ihering.

At Montevideo, in a creek in the Prado, the shells taken by Dr. Rush
are large, olivaceous, with noticeably more convex whorls. They measure :

8.2 " 3.9 " " 3.2 " " y#.

8-4 3-9 " 3-3 " 8#.

In a small spring back of the Cerro, Montevideo, the shells are similar
but smaller, about 5 mm. long with 6% whorls.

Shells from Rio Grande do Sul, sent by Dr. von Ihering, are about 6
mm. long, 2.3 to 2.9 mm. in diameter. The more slender shells are less
numerous than the stouter ones, and some are transitional in shape. The
color varies from dark to pale olive (Plate XLI<:, figs. 3, 4, 8). A small
form has been sent also from Ilha Comprida, near Iguape, on the Sao
Paulo littoral.

Melania dubiosa Clessin, judging from specimens sent from S. Leopoldo,
State of Rio Grande do Sul, by Dr. von Ihering, is identical with the
large form of L. australis noticed above from Montevideo.

Puerto Bertoni, Paraguay. Types No. 103,045, A. N. S. Phila., from No.

This species differs from Potamopyrgus peteningensis (Gld.) by its much
less convex whorls, smaller size and minute spiral striae. Potamopyrgus
scottii has far more convex whorls and coarser sculpture.

In some specimens from the type locality the spiral striae are extremely
minute and weak, yet visible under the compound microscope. These
were sent under No. 190 Museu Paulista.

A few other species at present referred to Litioridina, such as L. pedrina
Miller, have spiral sculpture ; yet the presence of this unusual feature raises
some doubt as to the genus, which can be definitely determined only by
examination of the genitalia. L. bertoniana may prove to belong to
Potamopyrgus.

ingensis (Gld.) which, however, has a smooth surface. The specimens
are bleached and apparently fossil, being filled with sandy mud. A
minute embryonic shell was obtained from the matrix washed out of one
of the specimens figured. This confirms the generic reference to some
extent, as all Potamopyrgus species are viviparous.

8.5 mm. long, 2.5 wide, with 6 whorls. One of the original lot is figured

(fig. 12). It measures 5.4 mm. long, 2.4 wide, the aperture 1.8 mm. long,
and is composed of 6^ whorls. The apex is very obtuse. Another lot,
received from G. von Frauenfeld, contains shells slightly more slender
than that figured. In one of them I found two minute embryonic shells.

IDIOPYRGUS gen. nov.

The shell is perforate, solid, turrite, with long spire of very convex
whorls ; aperture diagonal, oval, its plane sloping forward below, posterior
end rounded, sinused ; a small sinus at junction of the outer lip with the
basal margin. Lip slightly expanded, thickened within. Operculum
paucispiral, with the nucleus at the lower fourth, near the columellar
margin. Radula having the formula ^. 7. 9. 16.

Type, I. souleyetianus.

The snail for which this genus is proposed differs from all known species
of Littoridina by its internally thickened, somewhat expanded and bisinu-
ate peristome, the diagonal aperture, and by having fewer cusps on the
upper reflection of the central teeth, as well as on the marginal teeth. The
scoop-like shape of the outer marginal tooth is also rather peculiar.

FIG. 12.

Idiopyrgus souleyetianus, half row of teeth and an isolated marginal tooth.

Idiopyrgus has some resemblance to the Dalmatian genus Lanzaia
Brusina, and to the Mexican Pterides Pilsbry. In all of them the long
axis of the aperture stands strongly diagonal to that of the shell, the
posterior end of the aperture is rounded, effuse or sinused, the lip ex-
pands more or less, and the whorls of the tapering spire are strongly
convex. These apertural characters are so unusual in Amnicolidce, that I
am disposed to view them as indications of real relationship between the
three genera, rather than convergent structures in snails otherwise diverse.

PILSBRY: NON-MARINE MOLLUSCA OF PATAGONIA. 565

Unfortunately Lanzaia and Pterides are known by dead and bleached
shells only, so that the relationship suggested remains hypothetical. It
affords no safe basis for deductions concerning the antecedents of the three
groups, each known from a single spot, and separated from its supposed
relatives by thousands of miles.

The genera are characterized as follows :

Common characters : — Shell turrite, composed of very convex whorls ; aperture strongly
diagonal to the axis of the shell, oval, the posterior end rounded, spreading or sinused,
the basal margin also retracted or effuse ; peristome continuous, more or less expanding,
running forward below.

a. Shell openly umbilicate, thin, sculptured with sinuous longitudinal ribs and fine spiral

stria, minute (2 to 3 mm. long, with 6 whorls) ; the aperture elliptical, lip broadly
flaring. Dalmatia. Lanzaia Brusina.

b. Shell rimate, thin, smooth, minute (2.5 to 3 mm. long, with 7 to 10 whorls) ; the aperture

ovate ; lip sinused or spreading above, broadly retracted or spreading at the base.
Mexico. Pterides Pilsbry.

c. Shell perforate, solid, smooth, of about 71^ whorls ; the aperture oval, small, the lip

having a rounded sinus above and a smaller one at junction of outer and basal margins,
which expand but little. Southeastern Brazil. Idiopyrgus Pilsbry.

IDIOPYRGUS SOULEYETIANUS sp. nov.

(Plate XLI<r, Figs. 14, 140.)

The shell is perforate, solid, turrited, greenish-yellow, opaque. The
surface is smooth and glossy, growth-lines very faint. The spire tapers
regularly to a small but obtuse apex. Whorls 7^ , all strongly convex,
joined by deep sutures. The aperture is oval, oblique, the basal margin
being advanced, the outer lip retracting upward. The peristome is con-
tinuous, the outer lip expanded, somewhat thickened within. It has a
rounded sinus just below the upper insertion, and a small sinus at the junc-
tion of the outer and basal margins. The continuous columellar and
parietal margins are arcuate, forming a raised ledge across the parietal wall.

In old individuals the spire becomes more or less shortened by erosion
of the early whorls. This form differs from the Littoridinas by its peculiar
peristome. It is probably a straggler from the fauna of eastern Brazil, of
which little is yet known.

fied as P. lapidum}- In this form "the penis is inserted nearly on the
median line of the back of the neck (fig. 13). It was not found for a long
time, because the number of females far exceeded the males among the
animals examined. It is very broad at the base, provided with an obtuse
hump and runs somewhat coiled towards the right side, where its summit
lies near the base of the tentacle. It is perforated throughout by the vas
deferens, and terminates in a slender conical point, which is encircled by
a sort of prepuce."

Dentition of Potamolithus. — I have examined the teeth of P. rushii

narrow, and the side cusps are small. The cusps of the admedian tooth
are of about equal width, but are longer in the middle, as shown in fig.

numerous, and on the outer. they are still more numerous.

those of P. rushii, the difference in the figures being chiefly due to the
side teeth being shown in their natural positions, while in P. rushii they
are drawn from a frayed radula, as is usually done in allied genera.

The teeth of a form from the Santa Maria River, a tributary of the
Sinos, identified as P. lapidum (probably not that but an allied species)
have been figured by Dr. H. von Ihering, as having two basal teeth on

sembling P. I. siipersulcatus.

The eggs are deposited in plano-convex chitinous capsules about .6
or .7 mm. in diameter, adhering to shells and probably stones. The
embryonic shell is smooth, Naticoid or globular in probably all of the
species. So far as I can see, it is quite continuous with the neanic stage.
In all of the species studied, the earlier portion of the neanic stage is also
Naticoid. In some forms this shape persists to maturity, but in others
angles or carinae set in, their appearance dividing the period of youth into
two or three substages ; so that a highly specialized form may pass suc-
cessively through rounded, singly carinate, bicarinate, tricarinate, and
finally varicose stages. The degrees to which these sculpture-conditions
are accelerated and the stage finally reached, allow us to fix the relation-
ships and evolutionary grade of the several forms with some degree of
accuracy, in species where the young stages are accessible.

These little river snails live on and under stones, at and below low-
water mark, often in copious numbers. Up to this time, they have been
collected at comparatively few places, yet the range of the genus probably

PILSBRY: NON-MARINE MOLLUSCA OF PATAGONIA. 569

embraces the whole La Plata drainage, together with some rivers flowing
directly into the Atlantic, but having their rise adjacent to or interposed
between the head streams of the Uruguay and Parana Rivers. Many new
forms doubtless remain to be found, since only an inconsiderable part of
the waters of the Plata system have been explored for mollusks.

To what extent the specific characters of the forms vary from place to
place, we cannot say, since most of them are known from a single locality.
P. lapidum, which has been assigned a wide range, seems to vary with
locality, and probably several species will eventually be recognized in
what is now considered lapidum. Of most of the forms, many specimens
have been studied, some of them by hundreds, and I have been astonished
at the absence of intermediate or ambiguous individuals, such as one finds
in the fresh-water Pleiiroceratidce or Meldniidce. It is however well known
to those who have studied large quantities of fresh-water snails, that the
Amnicolidce are generally conservative ; the specific features are crystal-
lized, while in the Melanians they are fluid.

SIGNIFICANCE OF THE CHARACTERS OF POTAMOLITHUS.

In the Amnicolidce, as in the Viviparidce, the prevalent genera almost
everywhere are smooth-shelled forms with rounded or convex whorls.
Such forms have prevailed since the first appearance of these families. In
those Amnicolidce which are sculptured in the adult stage, the early
(embryonic and early neanic) stages are smooth or nearly so. These facts
apparently point to the conclusion that smooth, rounded shells are prim-
itive and sculptured shells derivative in these families.

Throughout Neocene time, carinate, varicose or otherwise strongly
sculptured species or genera of these families have frequently appeared,
but their distribution has been local and their duration brief. In some
cases the genesis of these sculptured or distorted forms from smooth and
normal types has been traced, as in the case of Viviparus hoernesi of the
Pliocene of southeastern Europe, and Viviparus altior and limnothauma of
the Floridian Pleistocene. At the present time, sculptured Viviparidce
and Amnicolidce are comparatively rare and confined to small areas.
Margarya in Lake Tali, Tulotoma in the Coosa River, Pyrgulopsis in
Pyramid Lake, Nevada, and Tryonia in a very restricted area in the
Southwest, are familiar examples. To these may be added the group of
carinate species of Potamolithus in the Uruguay River. In all of these

570 PATAGONIAN EXPEDITIONS : ZOOLOGY.

cases, the distribution of the forms is very restricted, often to a single lake,
or a few springs; and in some cases, as Pyrgtdopsis and Tryonia, we
have evidence that the species had a wider range in the Pleistocene and
are now apparently approaching extinction.

The facts indicate that in Amnicolidce and Viviparidce, shell-sculpture
is a phylogerontic character, showing the approach of senility of the race ;
strongly developed sculpture in a species signalizes its last incarnation.

The considerations advanced above go to show that the present Pota-
molithus fauna consists in large part of species which in an evolutionary
sense are aged, are more or less distinctly gerontic or senile. Over 80
per cent, of the species have characteristics which indicate, as experience
has shown, that they represent side lines of evolution, impotent to continue
the phylum, or to give birth to new phyla. There remains also a small
group of unspecialized species represented by P. lapidwm of the Parana
and its allies in southern Brazil.

I have been unable to find a shred of evidence to connect the develop-
ment of sculpture in these fresh-water snails with the concentration or
increased alkaline content of waters they inhabit, as some conchologists
have assumed. It is doubtful whether any such modified forms inhabit
alkaline or saline waters, while it is positively known that most of them
do not. Amnicolidce which live in brackish or sea water are not strongly
sculptured, but as smooth as their congeners in fresh water. Examples
of this are found in certain species of Paludestrina (P. minuta (Tott), P.
acuta (Drap.), P. salsa Pils.) and Littoridina (L. aitstmlis (d'Orb.), etc.).
It is extremely likely that these are forms of fresh-water origin, which have
become adapted secondarily to more or less saline waters. Part of them
live also in perfectly fresh water.

INTERRELATIONS OF THE SPECIES OF POTAMOLITHUS.

The species now known belong to four collateral phyla, each compris-
ing forms in several very diverse stages of specialization. The less dif-
ferentiated species in each phylum retain in adults a globular or Naticoid
shell without keels or angles, and in three of the groups have the lip
simple and unspecialized. This type of shell is common to other genera of
the subfamily. In all of the phyla some species have developed ortho-
genetically a varix or crest at the lip ; the shape of the shell is profoundly
altered by spiral keels in some species. These modifications are more or

less exactly parallel in the several series. I have attempted to express
the above ideas graphically in the following diagram, in which the least

[In these diagrams the most primitive, Naticoid species of each group are below ; those modi-
fied by the development of carinae above ; and the right-hand column contains derivative species
having the outer lip varicose. The connecting lines indicate the chief affinities of the forms.]

While the above diagrams are not intended for phylogenetic trees, all
the species being contemporaneous, yet it is likely that the ancestral forms
in groups II, III and IV did not differ materially from the least differ-
entiated of the recent species. It is significant that the only form known
to have a wide distribution, P. lapidum, is one of the least specialized of
the genus.

The evolution of carinae and varices in the several groups seems to have
been homoplastic. It will be shown below that the keels are superposed

upon the Naticoid form much earlier in some species than in others ; and
judging from these various degrees of acceleration, it would seem that the
specialized species are of unequal antiquity.

This species has some resemblance to P. hidalgoi, from which it differs
by the entirely different shape of the aperture, the swelling between keel
and suture, etc. The bisinuate outer lip, the texture and color-pattern of
the shell, etc., show it to be a carinate member of the group of P. bisinu-
atus. Described and figured from the type specimen.

Potamolithus sykesi Pilsbry, Nautilus, X, p. 88, Dec., 1896.

The shell is imperforate, globose-conic, rather solid, yellowish olive,
smooth and glossy, faintly marked with growth lines. The spire is conic,
truncate at the summit in adult shells of the type lot, about 3^ moder-
ately convex whorls remaining. The last whorl is evenly convex, smooth,
and expands strongly at the lip. There is a narrow umbilical crescent.
The aperture is very oblique and subcircular. The outer lip is strongly
expanded, built forward and convex beyond the expansion, and then
contracted, with three deep notches in its margin, one near the upper
insertion, another median, the third wider and basal in position. The
columella and parietal wall are moderately calloused, and the whole

Development. — The neanic stage in this species is like that of P.
bisinuatus. The ephebic stage is described above. A single gerontic
individual before me has built the median region of the outer lip forward,
obliterating the median notch of the lip (PI. XLI, figs. 2, 2.0).

This remarkable form is the most advanced of the bisinuatus phylum
known. It resembles P. bisinuatus in contour, and neanic shells of the
two species are distinguishable only by the bands of the latter, when these
are developed. The ephebic stage differs widely by the strong expansion
of the outer lip, its thickened and thrice notched face.

What relation P. bisinuatus and P. sykesi bear towards P. petitianus
(d'Orb.) of the Parana River is unknown, pending the discovery of the adult
stage of the latter, the specimen described and figured by d'Orbigny being
supposed to be immature. It is likely that petitianus will prove to be
different from either of the other species.

This may be the neanic stage of a species allied to P. bisinuatus ; but
in this group of forms (bisinuatus and sykesi] the neanic stage shows no
specific differentiation, the specific characters appearing only in the final
stage of development. Until the adult form of P. petitianus is collected
at the type locality, San Pedro on the Parana, no good purpose will be
served by uniting either of the other species to petitianus as its hypotheti-
cal adult. There remains also the possibility that P. petitiamis is a per-
manently undeveloped form, not passing beyond the neanic stage of the
bisinuate species, and therefore falling more properly in the lapidum
group. Compare also P. paranensis, p. 589.

(Plate XLI, Figs. 6-70.)

Potamolithus bisinuatus Pilsbry, Nautilus, X, p. 88, Dec., 1896.

The shell is imperforate, globose-conic, moderately solid, green or pale
yellowish-green, sometimes one-colored, but usually begirt with three nar-
row reddish-brown bands, one bordering the suture, another above the
periphery, and on the penultimate whorl visible above the suture, and the
third band below the periphery. The nearly smooth surface is weakly
marked with lines of growth. The spire is conic and rather high, trun-
cated at the summit in all adult shells seen, by the erosion of the early
whorls, about 3^ remaining. These are strongly convex, the last one
globose, without keels or angles of any kind, and with no expansion or
varix behind the outer lip. There is a distinct and concave but quite
small columellar area. The aperture is moderately oblique, round-ovate,
white or brownish inside. Its posterior angle is more or less filled with
a callous deposit. The peristome is edged with a black line. The thin
outer lip has a deep rounded sinus near its posterior insertion, and there
is a second sinus, wider and not so deep, at the base, the lip projecting
as a broad truncated lobe between the two embayments. The columella
is concave, narrowly calloused and the parietal callus is rather thick.

Development. — The shell is of the ordinary simple Naticoid shape
throughout the neanic stage, differing from P. lapiditm only in having a
longer spire. The peculiar Pleurotomoid sinuosities of the peristome
have their origin and development wholly in the ephebic stage. In this
respect, P. bisinuatus is like Pachycheilus dalli Pils., and differs widely
from Gyrotoma and Pleurotoma, in which the anal notch appears very early.

This species is related to P. sykesi, from which, however, it differs totally
in characters of the ephebic stage.

The shell is more slender than P. bisinuatus, acutely ovate-conic, green,
without color bands. The outer and basal margins of the peristome have
only shallow sinuses in place of the deep ones of P. bisinuatus ; the upper
one is often hardly perceptible, and, when developed, is nearer the upper
insertion of the lip than in bisinuatus. The inner margin of the peristome
is less heavily calloused, and the columellar area is excessively narrow,
hardly noticeable. The apices are perfect in the type lot, the shell con-

Development. — The young of about three whorls and 2 mm. diameter
are essentially similar to the adult stage in shape. The columella is
somewhat wider in proportion.

This is the smallest Potamolithus now known. It has the globular shape
of P. lapidum, but the wide columella of the neanic stage shows that P.
agapetus is related to P. buschii. It differs from P. buschii by the evenly
rounded shape of the last whorl, the diminutive size and clear green color,
as well as by the total absence of a peripheral angle or keel ; but the
young stages of P. buschii are not always readily distinguishable from im-
mature P. agapetus.

In some shells the aperture is smaller than in that figured, by reason
of a greater descent of the last whorl immediately behind the lip. The
columellar crescent varies from quite narrow, almost linear, to quite wide
and concave.

This snail has the texture, color and size of P. agapetus, from which it
differs by the longer, Amntcola-Vkz. shape and the small aperture. There
is no differentiated umbilical area.

Verhandlungen der k. k. zoologisch-botanischen Gesellschaft in
Wien, 1865, XV, p. 530, Taf. 11, first two figures.
The shell is obliquely trochiform, being flattened below, semiglobose
above ; moderately solid ; green or olive-green with irregular buff flecks
or zigzag streaks, and usually a dusky-brown band midway between the
periphery and suture. Surface with faint growth-lines and indistinct spiral
striae. Spire very short, the apex usually reddish. Whorls 4^/2 , convex,
the first one or two usually eroded in adult shells. The last whorl is
carinate, strongly angular, or with a rounded angle at the basal periphery,
very convex above the keel, and usually having a low ridge on the back
a short distance below the suture ; there is also, sometimes, a second
obtuse ridge below the upper one (fig. 13), much as in P. lapidum super-
sulcatus. Base flattened, but slightly convex. There is a well developed
concave columellar area bounded by an acute ridge. The aperture is
very oblique, ovate, the outer lip without a varix, but built downward
somewhat near and at the upper angle, contracting the aperture. The
columellar and parietal margins are heavily calloused ; columella rather
wide, concave and flattened.

Province of Colonia, Uruguay (type locality); San Gabriel's Island in the
La Plata, near Colonia, in the same Province, and Fray Bentos on the
Uruguay River (Wm. H. Rush).

Development. — At the end of the second whorl the periphery begins to
be weakly angular, the shell being about 2 mm. in diameter. Before that
stage the shape is globose-depressed, with a rounded periphery. At the
end of the third whorl the angle is strong. The columella is very broad,

its face concave, throughout the neanic stage. Figs, n, na represent a
young shell 3.3 mm. in diameter.

P. biiscJiii is related to P. agapetus, but it attains a larger size, and dif-
fers in the coloration and angular periphery ; yet there are some imma-
ture specimens in the lot from San Gabriel's Island, which approach very
near to P. agapetus. It differs from P. tapidum and P. tricostatus by its
wide columella at all stages of growth. It is a very abundant snail at
San Gabriel's Island, on the northern shore of the Rio de La Plata.

The figures on Plate XL represent the least angular forms of the
species from San Gabriel's Island. The type was a carinate shell, such
as that represented in Plate XLI<5, fig. 3, from Fray Bentos, on the Uru-
guay River. The ridge below the suture on the back is usually incon-
spicuous. Most of the specimens from San Gabriel's Island are similar
to those figured on Plate XL, or somewhat more angular, but less so than
shells from the mainland. They also have the ridges or sulcus on the
back more strongly developed in some examples.

POTAMOLITHUS CONICUS (Brot).

Lithoglyphus conicus Brot, Journal de Conchyliologie, XV, 1867, p. 69,

pi. i, fig. 5 (Uruguay River in the Province of Entrerios).
The shell is high-trochiform, rather straightly conic, solid, green or
brownish-olive, variegated with pale green or yellow zigzag streaks. The
smoothish surface is rather glossy, with the usual fine growth-lines. The
conic spire is longer than in related species, and often eroded at the apex.
Whorls nearly 4^ , convex. The last whorl slopes steeply and with little
convexity to the carinate periphery, which is basal in position. On the
back there is sometimes a very weak ridge below the suture and parallel
to it, but this is usually wanting. The base is flat, and there is a rather
wide crescentic, concave columellar area defined by a sharp angle. There
is no varix at the lip. The aperture is very oblique, symmetrically ovate,
in fully adult shells is contracted somewhat, being filled in above ; with
a continuous, black-edged peristome. The columella is concave and
narrow.

Uruguay River at Paysandu, Uruguay, under stones at extreme low

water.

Development. — The youngest shells at hand lack about one whorl of
completion. At this stage the shape is practically that of adults, except
that there is no columellar crescent and the columella is wide and flat.
The weak subsutural ridge, when developed at all, appears on the back
of the last whorl only. The most fully developed shells therefore have
the characters of the four-whorled stage in P. tricostatus, while most
shells, wanting the upper keel, are like tricostatus at the three-whorled
stage.

P. conicus differs from P. tricostattts by its smaller, size, more highly
conic shape, and the less developed sculpture of the last whorl. It is
more closely related to P. buschii, both having the columella wide during
the neanic stage ; but in the adult stage P. btischii is depressed and P.
conicus elevated in shape.

The color in life is probably always more or less green. The rich brown
tint of those figured may be due to change in alcohol, though I am not
sure that this is the case, as the shells were dry when they came into my
possession. A lot of P. buschii which had been in alcohol have changed
to brown, while all of those dried fresh are green.

POTAMOLITHUS ORBIGNYI Pilsbry.
(Plate XL, Figs. 1-5.)

Potamolithus orbignyi Pilsbry, Nautilus, X, p. 88, Dec., 1896.

The shell is imperforate, globose, solid and strong. Uniform olive
colored, or with brown bands below the suture and in the middle of the
last whorl, on an olive or green ground. Surface smoothish, with faint
growth-lines and fine, very indistinct spiral striae. The spire is very short
and conic. Whorls nearly 4^ , strongly convex, the later third of the last
whorl descending more rapidly. The last whorl is squarish, obtusely
biangular, being shouldered above, flattened in the middle, and more or
less angular at the basal periphery. The ample crescentic columellar area
is concave and bounded by an angle. The lip is strengthened by a narrow
varix, which is blackish and bevelled to the lip-edge. The aperture is
very oblique, and rounded-ovate. The outer lip is thickened within, the
inner lip heavily calloused. The columella is broad and flattened.

In the typical form of the species the flattening of the last whorl is
nearly vertical below the shoulder. In other examples (PL XL, figs. 2, 3)
the flattened surface slopes steeply, and the periphery is somewhat more
angular, though still rounded off. Young shells (PL XL, figs. 4, 4^) with
3^ whorls, having a diameter of 2.5 mm., have a distinct flattening above
the periphery, though less marked than in adults. This was not seen by
my artist, who drew the peripheral region of fig. 4 much too regularly
rounded. Fig. 5 represents a slightly larger shell, diam. 2.8 mm., the
basal aspect drawn to show the very broad, flat, columellar callus. In
contour it resembles fig. 2.

P. orbignyi is somewhat related to P. dinochihis, but differs in the
lower varix, absence of a spiral ridge below the suture, the larger columellar
area, broader columella, etc. It is similar to P. philippianus in shape,
but lacks the columellar furrow of that species.

POTAMOLITHUS JACUHYENSIS Pilsbry.
(Plate XXXIX, Figs. 3, 30.)

PotamolitJms jacuhyensis Pilsbry, Nautilus, XII, p. 113, Feb., 1899.

The shell is globose, solid and strong, smoothish, with the usual slight
growth lines and scarcely visible spirals ; covered with a strong, rich brown
cuticle, becoming more reddish towards the apex, and dark green below
the last turn of the suture, behind the lip, and at the base. Spire short
and conic. Whorls 4^ , those of the spire convex, the last very obtusely
biangular, being flattened peripherally, subangular at the shoulder, flat-
tened and sloping above it, and tapering basally. There is in some
specimens a well-developed flattened columellar crescent, but in other
individuals it is reduced and inconspicuous. The aperture is large and
somewhat spreading, moderately oblique and irregularly semicircular.
The outer lip is sharp, with a dark line at the edge, not expanded, and
not in the slightest degree varicose or contracted. The inner lip is
heavily calloused.

584 PATAGONIAN EXPEDITIONS: ZOOLOGY.

No immature stages are represented in the series before me. The
species belongs to the more primitive or youthful group, by its simplicity
of form, the absence of varices, and the want of contraction at the mouth.
It is not closely related to any of the La Plata drainage forms, but has
some resemblance to P. lapidum, from which it differs by the obtusely
biangular shape, the much larger aperture, and the heavily calloused
columella, which allies it to species of the Uruguay system, and those
following.

POTAMOLITHUS INTRACALLOSUS Sp. nOV.

The shell is imperforate, solid, globose with short, conic spire, olive-
green, blackish in the axial region. Surface very lightly marked with
growth lines. Whorls 43^ , convex, the last strongly convex below the
suture and at the periphery, which is below the middle, somewhat flattened
above the periphery ; base convex ; an acute keel divides off a crescentic
umbilical area. The suture descends slightly near the aperture. The
aperture is ample, oblique, very shortly oval. The peristome is black-
edged, not expanded. The continuous columellar and parietal margins
are very heavily calloused, the columella broad and flattened. In oblique
view in the aperture, a broadly rounded prominence is seen in the middle
of the columella.

This small species of the P. buschii group is notable for its very broad
columella, with an internal node or rounded prominence. This last
feature differentiates it from P. ribeirensis, which closely resembles intra-
callosus in shape.

POTAMOLITHUS RIBEIRENSIS sp. nov.

only. Spire short, conic. Whorls y/2 , convex, the last globose, most
convex at the periphery and just below the suture, the intervening surface
somewhat flattened in some examples, but strongly convex in others.
The periphery is very indistinctly subangular in front, but in fully adult

PILSBRY: NON-MARINE MOLLUSCA OF PATAGONIA. 585

shells this is often scarcely noticeable. The base tapers and is not very con-
vex. The suture descends very slightly in front. There is an extremely
narrow umbilical area. The aperture is oblique and ample, angular above.
The outer lip is thin and acute, and forms a half-circle. The columella
is very heavily calloused, its face flat or excavated, with a longitudinal
depression. Parietal callus heavy within, thin and adnate at the edge.

Rio Ribeira, Yporanga, State of Sao Paulo, Brazil. Types collected
by R. von Ihering, 1908.

This form resembles P. lapidum (d'Orb.) in shape, but differs by its
very broad columella and diminutive size. It is rather closely related to
P. bnscliii, though differing by the rounded periphery, which even in im-
mature shells shows the hardly noticeable trace of an angle. P. intracal-
losns is an allied species.

A series of eight shells from Hiririea, Rio Ribeira, State of Sao Paulo,
collected dead, but not bleached, has been submitted by Dr. von Ihering.
The cuticle is olive-green or clear green. The shape is about as in ribeir-
ensis. In several shells there is a very narrow umbilical area, defined by
a raised line. In the youngest shells, diam. 2 mm., the columella is very
wide, as in ribeirensis, but in the largest shells, length 5.2, diam. 4.2
mm., it is quite noticeably narrower. In one shell of this lot (Plate
XLI£, fig. 4) there is a wide, lunate, concave umbilical area, defined
by an acute black keel, the columella being wide, as in P. ribeirensis. It
measures, length 4.2, diam. 4 mm. Further material is needed to show
the status of this form, which for the present may be considered a race of
P. ribeirensis.

POTAMOLITHUS CATHARINE Sp. nOV.

aperture. The last whorl is strongly convex throughout ; near the aper-
ture it dilates a little. The aperture is slightly oblique, ovate, fleshy-
gray within, blue-white near the lip. The outer lip is thin and black at
the edge, and with the basal lip forms a half-circle ; in profile its edge is
even. The columella is heavily calloused, the callus extending across the
parietal wall, where it is less thickened. There is a distinct umbilical

"This species is closely related to the preceding (P. peristomatus] by
its short shape ; it differs constantly by wanting a carina, and by the non-
reflexed peristome" (d'Orbigny).

"P. lapidnm inhabits the whole course of the Parana and La Plata, from
well above Corrientes to Buenos Aires, or from 27° to 34° S. lat; on
stones, clinging in great numbers to the under side, at extreme low water.
It moves quite actively" (d'Orbigny).

The typical form of P. lapidum, figured by d'Orbigny, has an evenly
rounded last whorl, though his phrase, " le dernier [tour] est souvent
comme deprime," indicates that the Parana shells are frequently com-
pressed around the upper part of the last whorl. Mr. E. R. Sykes, who
kindly examined the types of the species for me, states that one specimen
is so characterized. The aperture is ample, the lip not in the least con-
tracted and not thickened, the columella only moderately thickened.

The variety dunkeri of Strobel, from the Rio de La Plata at Olivos, near
Buenos Aires, seems to differ from P. lapidum only by its small size ;
length 4, diam. 3.5 mm., with 4 whorls. It was described from a single
individual, and probably has no racial significance.

I have not seen typical P. lapidum from the Uruguay River.

In the State of Sao Paulo P. lapidttm has been reported by several
authors from streams flowing into the Atlantic, as quoted in the references
above, which I am unable to control ; but I doubt whether the true P.
lapidum is found in those waters.

A form of P. lapidum having the spire rather longer than d'Orbigny's
type figures is drawn in figs. 4, 5, 5« of Plate XXXIX. It is from the
Uruguay River, exact locality not noted.

At Paysandu, Uruguay a race occurs differing somewhat from typical

588 PATAGONIAN EXPEDITIONS: ZOOLOGY.

P. lapidum (Plate XLI£, fig. 5). The shell is solid, globose, with conic
spire longer than in P. lapidum, though the apex is eroded in all speci-
mens seen. Aperture smaller than in lapidum, somewhat contracted by
an internal thickening and contraction of the lip above. Columella
narrow. A very narrow umbilical area is defined by an angle, which runs
very close to the columellar lip. This race may be called var. elatior.

Length 4.5, diam. 3.5 mm.

The long spire separates this form at once from P.paysanduanus, which
moreover differs in the shape of the last whorl. In old examples the
aperture is more contracted than in that figured, and the spire is more worn.

Potamolithus lapiditm stipersulcatiis, Pilsbry, Nautilus, X, p. 88, Dec., 1896.
The shell is like P. lapidum in its globular shape. It is dark green,
usually with pale, irregular zigzag markings, sometimes confined to the
spire, and there is usually an indistinct brownish band above the pe-
riphery. On the last whorl an obtuse ridge revolves not far below the
suture, most prominent on the back ; this is followed by a concavity,
below which there may be a second obtuse angle. The base is quite full
and rounded. The suture descends suddenly to the aperture, which is
therefore a little contracted, oblique and ovate. The peristome is acute,
dark-edged, continuous, without trace of a varix. The columella is
narrow and concave, and the parietal wall is only moderately thickened.

Development. — The spiral ridges appear only on the last whorl, and
usually only on its last half. Up to that time the whorls are rounded and
the shape Naticoid. At all stages of growth the columella is quite narrow.

Potamolithus I. supersulcatus is quite closely related to P. tricostatus
(Brot), from which it differs chiefly by the weaker spiral ridges, which are
only one or two in number, not three, as in P. tricostatus. These ridges
are not only less emphatic in supersukatus^ but they do not appear so

PILSBRY: NON-MARINE MOLLUSCA OF PATAGONIA. 589

early in the development of the individual. The narrow columella is
similar in the two species.

The specimens from Fray Bentos and Paysandu (where only a few were
taken), have no second angle below the upper spiral ridge on the back.
It is a very abundant snail at San Gabriel's Island. Specimens preserved
in alcohol become brown when dried ; and this is also true of most, prob-
ably all, of the dark green species.

The figures by von Iterson, on Plate XXXIX, represent a very dark
green specimen. They are not so characteristic as that on Plate XLI«,
which shows the back of an example with the color-pattern fully developed.

fine growth-lines and very fine, indistinct spiral striae. Whorls strongly
convex, the last swollen below the suture, in its latter part flattened below
the swelling, rounded at the periphery and base. The aperture is very
oblique, ovate, outer lip thin and sharp. Columella moderately calloused.

From the sharpness of the outer lip, I am disposed to think that none
of the specimens is fully mature, though the largest one must be nearly
so, as it is eroded like an old shell. It differs from P. lapidum by the
longer spire, small size and pale color. There are two specimens in the

that of the Museu Paulista.

for weak growth-lines, shining. The spire is very low, conic, the apical
whorls eroded in all the individuals seen ; three whorls remaining are
strongly convex. The. last whorl is swollen below the suture, then some-
what flattened, rounded at the periphery and base. The suture descends
abruptly to the aperture in fully adult shells. The aperture is somewhat
oblique, ovate. The peristome is black, with obtuse, flat edge ; the outer
and basal margins are narrow ; the upper part of the outer lip and the
upper angle are wide, and the columellar and parietal margins are very
wide and flat, black, contracting the aperture.

This form differs from P. lapidum by its contracted aperture, the inner
and upper margins of the peristome being heavily thickened within, the
thickening covered with a blackish cuticle. In P. lapidum the aperture
is ample, with no such heavy thickening. In the stage immediately pre-
ceding maturity the columella has a moderate white callus within, and
the parietal callus is quite thin. The type specimen is figured. Six
others I have seen show no significant variation.

With these specimens two other forms were sent which seem to be
phases or varieties of the same species, but not intergrading in the mate-
rial examined. Whether they occurred in the same or in separate colonies
is not known.

Form SINULABRIS (Plate XLIa, figs. 2, 3). The shell differs from typical
P. paysanduanus by having a low rounded ridge behind the outer lip,
which is black, contracted, and has a rounded sinus above. The basal lip
is narrow and a little retracted. The columellar and parietal margins are
not so broad as in paysanduanus. There is an excavated umbilical area,
but it is generally not distinctly defined by an angle. The shape is other-
wise as in P. paysanduanus.

Form IMPRESSUS (PI. XLI#, figs. 4, 40). The shell resembles typical
paysanduanus as far as the middle of the last whorl, after which it has an
impressed, concave zone a short distance below the suture, and usually a
sinus in the upper part of the lip. The outer lip is thin and sharp, with
no external varix or swelling. The shell, under the cuticle, is light yellow.

Length 5, diam. 4.8 mm.

Up to the time of reaching the size of adult P. paysanduanus, this form
grows normally. After that, instead of forming a contracted aperture, it
adds a half whorl, which is distorted by a superior concave zone and finally
terminates with a thin outer lip. The specimens were sent with typical
paysanduanus.

The shell is solid, imperforate, light olivaceous-brown, lightly marked
with growth-lines, shining. The spire is very short, y/2 whorls remain-
ing, the apex being eroded. The penultimate whorl has a strong angle
at its upper third, is flat and horizontal above the angle, flat and sloping
below it. The last whorl is bicarinate, the peripheral and shoulder carinae
being about equally strong, giving it a square appearance. The base
tapers to a rather high ridge, which bounds a wide, excavated, umbilical
area. The peripheral angle becomes obsolete just behind the outer lip,
and it is visible only on the last whorl. The aperture is very oblique,
ovate, white within. Peristome a little contracted, its face flat and thick-
ened within, at and above the periphery and in the upper angle ; below
the periphery it is thin and a little retracted. The columella and parietal
wall are moderately calloused, a groove in the face running parallel to
their outer margin.

This snail differs from P. carinifer in the shape of the last whorl, the
much stronger upper keel (which is developed earlier) and in having a
large umbilical area. It lacks the median keel and variegated colora-
tion of P. tricostatus.

A young shell 2.4 mm. diam. consists of 2>£ whorls, the first il/2 are

(Plate XLIa, Figs. 5, 50.)

The shell is imperforate, trochiform, solid, blackish-brown in old
individuals, the shell of a brick-red tint below the cuticle. Surface lightly
marked with growth-lines. The spire is very short, conoidal. Whorls
about 4, the earlier ones convex. The first half of the penultimate whorl
is convex ; then a small carina gradually arises a short distance below
the suture, the surface flat and sloping below it ; a little later a strongly
projecting keel appears just above the lower suture, being uncovered by
the descent of the last whorl. The last whorl has a strongly projecting

PILSBRY: NON-MARINE MOLLUSCA OF PATAGONIA. 593

peripheral keel and a small keel near the suture, the surface flat between
the keels. The base is a little convex. The umbilical area is slightly
excavated, but not bounded by a ridge or keel. The suture descends
slowly in its last third of a whorl, and then rapidly at the aperture. The
aperture is very oblique, shortly ovate, flesh-tinted inside. Peristome
blunt, not expanded. Columella concave, rather narrow, its face slightly
grooved. Parietal wall rather heavy-calloused.

Length 4.2, diam. 4.1 mm.

Paysandu, Uruguay. Dr. Florentino Filippone.

This species closely resembles P. microthauma, from which it differs
by the entire absence of a varix behind the outer lip ; the coloration is
also different, but the type is probably abnormally dark, being an old shell
which has lost part of the cuticle.

Lithoglyplius tncostatus Brot, Journal de Conchyl., XV, 1867, p. 68, pi. i,

fig. 4 (Uruguay River, Province of Entrerios).

The shell is trochiform, solid and strong ; olive-colored, profusely
marked with irregular or zigzag buff spots. The surface is glossy when
clean, with the usual weak growth-lines and minute spiral striae. Spire
short, convexly conoidal. Whorls 4^ , the first three convex. A ridge
then gradually appears below the suture, increasing to a strong carina on
the back of the last whorl. The last whorl has also a thick, strong keel
defining the base, and a short keel, chiefly dorsal, above the middle of the
slightly convex surface between the two keels. The base is flattened, but
a little convex ; a small columellar area is usually distinctly differentiated.
The last whorl expands slightly at its termination, and then contracts.
The aperture is very oblique, rounded-ovate, bluish-white within. The
peristome is continuous, black-edged. The columella is narrow and con-
cave ; and, with the parietal wall, is moderately calloused.

upper and lower keels are already strongly developed near the lip, but
there is no trace of the intermediate keel, which in adults is less than one
whorl long. The two keels present are very weak at the beginning of
the fourth whorl, the basal one stronger there than the upper, so that
apparently at 2>£ whorls the form must be Naticoid, like P. lapidum.
The next stage, at about 3 whorls, would have a basal angle only, like
P. buschii. The columella is narrow, as in P. lapidum, throughout the
neanic stage. The ephebic stage is marked by a slight expansion, forming
a narrow and low varix. Fully adult shells are markedly gerontic by
reason of the strong post-variceal contraction.

The figures of this species given by Brot are unsatisfactory from being
too small properly to show its characters. The median keel is shown too
low in position. The original locality was indefinite, but comprised an
area including the river in the neighborhood of Paysandu. Three speci-
mens of the original lot, received from Dr. Brot, agree with those col-
lected by Dr. Rush at Paysandu.

POTAMOLITHUS HATCHERI Sp. nOV.
(Plate XXXVIII, Figs. 6, 6a.)

The shell is imperforate, turbinate, solid and strong, pale yellowish-
green, becoming darker and narrowly streaked with dark green on the later
half of the last whorl ; on the penultimate whorl the color changes to rich
reddish-brown, becoming darker towards the summit. Surface glossy, with
faint growth-lines and fine, indistinct spiral striae. >Spire conic, high and
rather slender, the apex lost in the type, a pit in its place. Three whorls
remain, the first two of them evenly convex. The last fourth of the
penultimate whorl is very obscurely biangular, the lower angle more dis-
tinct than the other. These angles are more pronounced on the face of
the last whorl, and on its later half the upper angle rises into a strong keel,
the surface above it concave ; at the same time, the lower angle loses in
prominence, and is quite lost behind the lip. An extremely weak spiral
ridge is developed on the back below the suture. The base is rounded.
The last third of a volution of the suture descends more rapidly. There
is no trace of a varix at the lip. The aperture is quite oblique, as wide as
high, almost circular, but slightly angular above. The lip is obtuse, thick-
ened within, with a continuous blackish marginal line. The columella is

PILSBRY: NON-MARINE MOLLUSCA OF PATAGONIA. 595

very concave, and not wider than the outer lip, and is bounded outside by
a linear, hardly noticeable columellar area.

Length 5.5, diam. 4.9 mm.

Uruguay River, at Paysandu, Uruguay. Type, No. 90,218, A. N. S. P.

This species is based upon a single specimen, quite adult and to all
appearance perfectly normal, yet so unlike other known species that its rela-
tionships are doubtful. The prominent characters of P. hatcheri are the
elevated and tapering spire and the approximation of the two angles of the
last whorl, the upper one finally dominating, while the lower becomes obso-
lete on the last half of the last whorl. The absence of a lip-varix and of
a noticeable columellar area, as well as the rather narrow columella, are
features like the P. lapiditm group. The young shell, up to the middle of
the penultimate whorl, must be ovate, without angles ; but in the absence of
immature specimens, not much can be said of the development of the species.

It is named to honor Mr. J. B. Hatcher.

POTAMOLITHUS DINOCHILUS Pilsbry.
(Plate XXXVIII, Figs. 5, 7, 7a, 76, 8.)

Potamolithiis dinocJiiliis Pilsbry, Nautilus, X, p. 87, Dec., 1896.

The shell is globosely trochoidal, imperforate, very solid and thick ;
green, profusely marked with irregular, zigzag buff streaks. The surface
is smoothish, with the usual faint growth-lines and indistinct fine spiral
striae. The spire is conic, rather high when preserved entire (fig. 8), but
worn to a blunt summit in all adult shells seen. There are 4^ whorls,
but only 2^ to 3 remain in adults. The earlier whorls are rounded, but
at the beginning of the last a small ridge arises a short distance below the
suture. The last whorl is somewhat flattened and slopes steeply to the
basal periphery, which is full and narrowly rounded or subangular. The
ridge below the suture is narrow, but well developed on the back. The
columellar area is ill-defined and very narrow. The lip is strengthened
by a varix, which above the periphery is very high, massive and recurved,
but becomes weak at the base. The aperture is very oblique, contracted,
irregularly rounded, with the margins built out beyond the varix, con-
tinuous around the mouth, thick and obtuse. The columella is strongly
concave, and moderately calloused, not more than the lip generally.

Development. — The series at hand contains no young shells, one only
(PI. 38, fig. 8) has not yet formed the post-variceal contraction. It ap-
pears however that, until the last whorl is reached, the'shell has the primi-
tive Naticoid shape. The last whorl represents morphologically the
second neanic substage of such accelerated forms as P. microthaiima. The
strong post-variceal contraction and heavy thickening of the inner margin
of the peristome declare that the last stage is distinctly gerontic.

P. dinochilus differs conspicuously from P. microthauma, hidalgoi and
peristomattis by the absence of a peripheral keel, and from P. orbignyi
by the shape of the last whorl and the ill-developed columellar area. It
has perhaps more in common with the P. lapidum group, especially in the
coloration and the persistence of the Naticoid form to the beginning of the
last whorl ; but the very high, massive lip-varix of P. dinochilus is a fea-
ture unlike any of the lapidum group.

POTAMOLITHUS HIDALGOI Pilsbry.
(Plate XXXIX, Figs. I, la, i£.)

Potamolithus hidalgoi Pilsbry, Nautilus, X, p. 87, Dec., 1896.

The shell is imperforate, trochoidal, with flattened base and conic spire ;
moderately solid. The type specimen is dull reddish-brown, somewhat
olive-tinted at the base, and olivaceous blackish on the lip-varix ; . but
some immature shells of the original lot are dull olive-colored, darker on
the keel. The surface is slightly marked with growth-lines. The spire is
conic. There are 4^ whorls, the first 2^ convex; then a keel appears,
immediately above and filling the suture. The last two-thirds of the last
whorl descends slowly, the peripheral keel projecting above the suture.
The last whorl is flat and slopes steeply above the peripheral keel, and is
slightly convex below it. A very narrowly crescentic columellar area is
defined by an inconspicuous, but acute angle. The outer lip is strength-
ened by a moderately strong varix, not continued below the termination
of the peripheral keel. The aperture is extremely oblique, rounded-ovate,
angular above and indistinctly so outwardly, at the termination of the
keel. The columella is arcuate and moderately calloused.

Length 5.2, diam. 5 mm.

Uruguay River, at Paysandu, Uruguay. Types, No. 69,687, A. N. S. P.

A very weak ridge below and near the suture may be seen in two
immature shells of the type-lot, but this is not developed in the others.
The early neanic substage is Naticoid, like the corresponding age in P.
microthaiima. The rest of the neanic stage is the equivalent of substage
2 in P. microthaiima. The deep descent of the last whorl gives a markedly
gerontic character to the adult stage. P. hidalgoi is therefore less evolved
sculpturally in wanting the third neanic substage, senile characteristics
supervening earlier.

The species is named in honor of Dr. J. G. Hidalgo of Madrid, author
of a beautiful work on the mollusks of the Spanish Commission to South
America, among many other important labors.

POTAMOLITHUS MICROTHAUMA Pilsbry.

(Plate XXXVIII, Figs. 2, 20, 26, 3.)
Potamolithus microthauma Pilsbry, Nautilus, X, p. 87, Dec., 1896.

The shell is imperforate, biconic, very solid and strong. The last whorl
is olive-green, rather profusely marked with irregular buff maculae, which

598 PATAGONIAN EXPEDITIONS I ZOOLOGY.

are sometimes absent on the base. The lip-varix is bright green. On the
penultimate whorl the ground-color changes to purple-brown and the
markings disappear, the earlier whorls being uniform dark purple-brown.
The surface shows delicate growth-striae and a very minute, almost effaced
spiral striation. The spire is conic, with straight outlines, the apex entire
and obtuse, though small. Whorls 5, the early ones convex, the first 2%
being rounded, without trace of keels. A peripheral keel then begins,
strong from the beginning, and projecting flange-like above the suture.
The last whorl descends slowly from about its last third and much more
rapidly near the aperture. The peripheral keel projects very strongly and
is slightly undulating ; and a small keel arises below the suture, becomes
stronger on the back, then gradually decreases. On the base, midway
between the periphery and center, a low keel revolves, the area within it
being nearly flat. There is a very narrow crescentic columellar area.
The outer lip is strengthened by a very high and massive varix, which is
recurved above, with a rib on its face running to the lip-edge, and below
passes into the basal keel. The aperture is very oblique, ovate ; the outer
lip thin at the edge. The columella is narrowly calloused and regularly
concave.

Development. — The neanic stage is sharply divided into

(1) A lapidum substage, in which the shell is rounded, without keels,
comprising the first 2^ whorls.

(2) A carinate substage, initiated by the almost abrupt rise of the periph-
eral carina. From a half whorl to a whorl this is the only keel developed.
This stage corresponds to the adult P. hidalgoi, and is of brief duration.

(3) The basal and the subsutural carinae begin, weak at first, becoming
stronger near the end of the substage.

The ephebic stage is announced by the expansion to form the varix,
which, however, is not terminal, the whorl continuing and contracting
beyond it, thus assuming gerontic characteristics.

P. microthauma is related to P. hidalgoi and P. peristomatus, but it is
a much more evolved form than either, structures added in the second

POTAMOLITHUS RUSHII Pilsbiy.

(Plate XXXVIII, Figs. I, la, \b, 4.)

Potamolithiis rushii Pilsbiy, Nautilus, X, p. 89, Dec., 1896.

The shell is imperforate, wider than high, biconvex, very solid and
strong ; light green, the last half of the last whorl dusky green, the keels
rather bright green ; the early whorls being dark reddish-brown. The
surface is somewhat glossy, with faint, fine growth-lines and barely per-
ceptible spiral lines. The spire is convex, the apex obtuse. Whorls 4,
but the first is eroded, leaving a pit, in all the adult shells seen. The
whorls are convex, with seam-like sutures. In the latter part of the pe-
nultimate whorl the peripheral keel is usually visible at the suture. The
last whorl has a very strong peripheral keel, the surface being concave
above and below it. Above the concavity the upper surface is convex,
the convexity rising into a hump on the back, then disappearing, the last
fourth of the whorl being flat. The base has a thick and prominent keel,
defining a concave yellowish columellar area. The outer lip has a high,
narrow varix at the edge. The aperture is very oblique, short-ovate,
nearly circular, with a continuous, black-edged margin. The oblique
columella is very broad, with a gutter or concavity near to and parallel
with the inner margin.

Development. — The youngest specimens seen have three whorls and a
diameter of 3 mm. They have the depressed contour of adults and are
strongly carinate peripherally, but the carina is distinctly weaker in front
of the mouth, apparently indicating that it begins when the shell has
nearly two whorls and a diameter of about a millimeter. At the 3 mm.
stage the columella is very broad, semicircular, with a deep excavation and
rodrlike inner border (PI. XXXVIII, fig. 4). Very late in the neanic stage
the basal keel appears, the shell then being about 5 mm. in diameter ; the
columellar area being very narrow, at first linear. The rib or convexity

600 PATAGONIAN EXPEDITIONS I ZOOLOGY.

of the upper surface is also of late appearance, these structures belonging
to the third neanic substage, the second, or unicarinate, substage thus
occupying the greater part of the neanic stage. The discontinuation of
the upper ridge or hump initiates the ephebic substage. The marginal
varix and the absence of any tendency of the last whorl to descend or
loosen its coil anteriorly, show that this species is at its acme. It has
none of the stigmata of senility which are so manifest in P. micro-
thauma, P. hidalgoi, etc.

There is some variation in the degree of depression of the whole shell,
the amplitude of the columellar area and in the prominence of the hump
on the back, which is sometimes almost suppressed. The size also varies,
one specimen before me with the varix nearly complete measuring only
5 mm. in diameter.

The relationship between P. rushii and P. iheringi is exceedingly
interesting. The two species are similar in general color-scheme, in the
varix, absence of more rapid descent of the suture towards the mouth,
etc., but are totally diverse in contour, the one being carinate, the other
smooth and Naticoid. Yet it is significant that while P. iheringi has no
trace of a peripheral keel, the green band occupies the same position as
that coloring the keel in P. rushii.

POTAMOLITHUS IHERINGI Pilsbiy.
(Plate XXXIX, Figs. 2, za.)

Potamolithus iheringi Pilsbry, Nautilus, X, p. 87, Dec., 1896.

The imperforate or rimate shell is globular-conic, very solid and strong,
pale olive-yellow, with a sharply defined, bright green band bordering the
suture below and another immediately above the periphery, visible as a
narrow border on the penultimate whorl above the suture ; the columellar
area being also dull green. Very faint growth-lines and an almost effaced
spiral striation are visible under the lens. The spire is low conoidal, the
suture clearly incised but not impressed. Whorls 4^ , the first half whorl
usually lost in adult shells ; the rest are slightly convex, the last whorl
being globular, at first regularly rounded, but its last third descends slowly,
and is perceptibly flattened obliquely in the peripheral region, being more
full and convex below. The base is convex, but there is a concave cres-
centic columellar area defined by an inconspicuous angle. The outer lip
is strengthened by a moderately strong varix, bevelled to the lip-edge,

PILSBRY: NON-MARINE MOLLUSCA OF PATAGONIA. 60 1

and weak at the base. The aperture is quite oblique, ovate, subangular
above. The outer lip is thick within. The columellar margin is some-
what straightened, the columella very wide, flattened and excavated, a
rather deep furrow running parallel with and near to the inner edge.

Development. — The youngest individuals seen have 3^ whorls, with a
length of 2.3 and diam. of 2.8 mm. They are therefore more depressed
than the adult stage, and have both green bands well developed. The
subsutural green band begins at the end of the second or beginning of
the third whorl. The axis is wholly imperforate. The columella is very
broad, half-round, with the excavation in its face deeper than in adults.
At no stage are there any traces of carinae or protuberances.

I have seen a long series of this species. The characters described
above are very uniform, and it is readily known by the Naticoid shape,
grooved columella and green bands. Named in honor of Dr. H. von
Ihering.

POTAMOLITHUS PHILIPPIANUS Sp. nOV.
(Plate XLI£, Figs, i, \a, 2.)

The shell is globose, solid and strong, light greenish yellow, with a
narrow dark green border below the suture, the apex pinkish. The surface
is nearly smooth, showing faint growth-lines and fine, very indistinct
spiral striae. Spire low, conic, the apex minute, entire. Whorls 4^ ,
convex, the last not more rapidly descending, distinctly flattened periph-
erally, shouldered above the flattened zone, very obtusely subangular
below it, the base convex, with a rather wide, concave and crescentic
columellar area, the lower portion of which is bounded by an angle. The
outer lip is strengthened by a moderately high varix near the margin, much
lower at the base, and continuous with the angle bounding the columellar
area. The aperture is very oblique and semicircular, the outer margin
being deeply arcuate, the inner somewhat straightened. The columella is
rather broad, with a shallow furrow on its face ; and the outer edge is
somewhat elevated near the insertion, leaving, in the type specimen, a
shallow crevice behind it, not visible in younger shells.

Development. — The smallest specimens seen measure 3 mm. diam.,
2.8 high. The peripheral flattening is already weakly perceptible. There
is no trace of a basal angle or columellar area, but the columella is very
wide, almost semicircular, with a deep excavation in its face. The angle
bounding the columellar area is developed very late, appearing only on
the last whorl.

This species is described from four specimens, none of them perhaps
completely mature. The shell figured is almost mature, but lacks the
post-variceal contraction of the lip, which would probably be acquired.
Two of the shells have a peripheral brown band, fading out at the edges,
and one has a second fainter band on the outer part of the base.

Compared with P. iheringi, this species differs by its somewhat biangular
shape, the lower varix and the coloration. P. paysandtianus differs more
radically by its columella.

The shell is thin, nearly equilateral, pale straw-yellow, glossy, finely
striate. The beaks are low and broad, the embryonic stage marked off by
a contraction or gutter. Anterior end almost symmetrically rounded; pos-
terior end slightly flattened or subtruncate. Hinge-line arched. Cardinal
teeth very minute, double in the right, single in the left valve. Lateral

This species is closely related to Musculium argentinum (d'Orbigny),

The shell is fragile, olive-gray when full-grown, the young ones grayish,
with a yellow zone at the basal edge. The ends are more abrupt than
in M. patagonicum, and the beaks fuller. The teeth are decidedly more
delicate and compressed than in M. patagonicum.

In the fresh specimens from 65 miles north of the Rio Chico the right
valve has below the beak a horizontal arcuate tooth, with a straight
oblique tooth above it nearer the anterior (short) end. The laterals appear
to be smooth. The left valve has a rather long slender tooth, lower and
angulated in the middle, the anterior ramus stouter and longer than the
posterior. The lateral teeth arise under the visible part of the umbones
(while in P. patagonicum they arise beyond it). They are high and tri-
angular in profile (fig. 16). The shells are light olive externally, with

of another anterior to it. These teeth, especially the anterior one, are too
distinctly defined in fig. 10. Lateral teeth very short and moderately
strong, distant from the beaks.

Springs on the Rio Chico, fifteen miles (type loc.) and thirty miles above
the Sierra Oveja ; twenty-five miles below the Rio Belgrano ; and in the
Arroyo Eke, near the head waters of Spring Creek, 2400 ft. elevation.

This clam differs from P. magellanicum by the shorter anterior end, short
lateral teeth remote from the cardinals, the anterior laterals standing at an
angle approaching 100° with the posterior laterals, on account of the curva-
ture of the anterior margin. In P. magellanicum the angle of divergence
of the teeth is decidedly greater, and they are longer. The cardinal teeth
are almost obsolete in P. patagonicum, not projecting above the level of
the hinge.

In the type lot, as well as in all the specimens from springs recorded
above, the surface is straw-yellow and the striation fine and even, without
periodic lines indicating growth-arrest. In specimens from small streams
in the same region the shell attains a greater size, up to length 6.9, alt.
5.8 mm., and is marked externally with several darker concentric streaks,
indicating periods of growth-arrest ; the color is generally paler. This
form, which may be called var. zonifer, is figured on Plate XLVItf, fig. 9.
It is from small streams on the Rio Chico fifteen and twenty-five miles
above the Sierra Oveja.

there are two narrow teeth, parallel, oblique and contiguous. In the left

It may be well here to correct the nomenclature of an allied genus of
the La Plata and Amazon basins, formerly known as Castalia Lam., 1819.
This name was believed to be preoccupied by Savigny, in l^ermes, and
Tetraplodon Spix, 1827, has been substituted for it.

The late Professor Eduard von Martens wrote to me under date of 18
Oct., 1893, as follows : " Concerning Castalia, the date of Savigny's genus
of Annelids is given as 1817 in Agassiz's ' Nomenclator,' it is true, but I
am not sure that this is correct. I find Savigny's genus first in his Sys-
tem of Annelids, which is said to have been published in 1820, whereas
Castalia Lamarck was published in 1819, vol. V, part I, of Lamarck's first
edition [of the Animaux sans Vertebres\

"P. S. I have consulted in these days the original edition of L. Agas-
siz's Nomenclator and I find concerning Castalia the note :

" ' Castalia Sav., Syst. annelid., 1817. Savigny Systeme des Annelides,
presente a 1'Acad. des Sci. en 1817, public en 1826.'

"It is true that there is also an edition of the same work, in folio,
which makes part of the large ' Description de 1'Egypte,' and to which in
Engelmann's Bibliotheca Zoologica, vol. I, p. 581, the date 1820 is given.
By general consense the date of publication and not the date of finishing
a manuscript and presenting it to a learned body is accepted as fixing the
priority. I come to the conclusion that Castalia Lam., 1819 can stand
for the shell, and Castalia Sav. among the Annelids is to be changed."

NOTES UPON THE CHARACTERISTICS AND ORIGIN OF

THE NON-MARINE MOLLUSCAN FAUNA OF

SOUTH AMERICA.1

In the following synopsis I have limited myself to a brief consideration
of data derived solely from mollusks. This course is not due to any
underestimation of the value of other groups in biogeographic work ; but
rather because conclusions drawn from a group known to me at first
hand have a certain value which would not attach to borrowed data. The
classification used herein is that of the Manual of Conchology so far as
the groups have been considered in that work.2

It must constantly be borne in mind by those comparing the distribu-
tion of non-marine mollusks with that of vertebrate groups, that not
only has evolution proceeded more slowly in the former, but migrations
have been slower. Thus, when a Pliocene communication was established
between North and South America, there was a rapid and extensive
invasion of both areas by mammals ; but the molluscan invasion was very
much slower and never extended nearly so far. Land and fresh-water
mollusks are restrained by conditions which affect mammals and birds far
less, such as areas with little forest, unsuitable or very scanty rock on the
surface, or short river systems, not well connected.

Any inquiry into the antecedents of a fauna leads to the question of
where its component groups had their rise. The rarity of land and fresh-
water shells as fossils, and the great antiquity of the family groups, renders
this question very intricate. The origin of many groups is still quite un-
known ; yet most of the larger families of land-snails, and a few of the
fresh-water groups may be traced back with considerable certainty, if not
to definite centers, at least to extensive areas of evolution.

The several origins of air-breathing gastropods from marine groups —
from the Opisthobranch stock, the Rhipidoglossa and the Taenioglossa

mann, Princeton University Expeditions to Patagonia, IV. T. Arldt, Die Entwicklung der Kon-
tinente, Leipzig, 1907 ; bibliography on pp. 622-631.

2 The family groups of land snails almost all differ widely in contents and limits from those
of Fischer's Manuel and other systematic works ; a fact of first importance in dealing with the
distribution of the groups, and the relationships of faunas.

6l2 PATAGONIAN EXPEDITIONS I ZOOLOGY.

— reach far back in Palaeozoic time. We have no data bearing upon either
the time or place of these events.

I. We have first to do with a fauna composed mainly of the Orthure-
throus land-snails1 — forms which are structurally but a step removed from
the aquatic pulmonates, and now forming an insignificant element in conti-
nental faunas, though still dominant in the islands of the central Pacific.
The families ISalloniidce, Enid<z, Pupillidce, PartnKd&% Ferussacidce,
Amastridcz, Achatinellidce and Tornatellinidce are remnants of this fauna,
which was doubtless once nearly or quite world wide, and probably attained
its acme in Palaeozoic time. The Heterurethra (Succineidce, etc.) doubt-
less existed in this early fauna, as well as the Aulacopoda (EndodonticUz
are known from the Carboniferous), and the Helicinidce. Of the fresh-
water forms probably represented in this fauna, we may mention the
ancestral stock of fresh-water pearly mussels, the Cyrenacea, the ancestral
Melanopsidce and Melaniida, and the Lymnceidce. With the rise of the
Sigmurethrous snails, the land-snails of this primitive fauna declined in
all continental areas.

One of the most remarkable features of the South American fauna is
the extreme scarcity of these primitive Orthurethrous land-snails. This
group is represented only by a few Pupillidce and Ferussacidce, probably
derived from Middle America in the Tertiary, and closely related to Antil-
lean and Mexican species.

The origin and early differentiation of the Sigmurethrous land-snails is
unknown. At the time of their appearance as fossils, in the late Cretaceous
and Eocene, the modern families were already more or less clearly blocked
out, so far as they are represented by known fossils. From the evidence
at hand, derived from the distribution of the groups in the recent fauna,
and as Cretaceous and Tertiary fossils, it appears that the evolution of
these families had proceeded during Mesozoic time in two chief areas, for
which we may use terms proposed in another connection by Dr. Theodore
Gill.

III. Eogceic or Southern fauna, which occupied chiefly the Gondwana
continent, including a large part of South America, tropical and south
Africa, and stretching in a great arch, possibly at no time perfect, to penin-
sular India and Australia. Here were evolved the families :

Mutelidce. Acltatinidce.

Etheriidce. Aperidce.

Ampullariidce. Rhytididcz.

Chilinidcz. Streptaxidcz.

Acavidcz. Circinariidtz.

Strophocheilidcz. Veronicellidce.

Bnlimulidcz.

The South American fauna is largely made up of groups of typically
Eogaeic or Southern origin, but there are also northern forms, derived
from Middle America (" Antillia"), and a few groups of ancient and
unknown origin. These several elements are as follows.

I. PRIMITIVE GROUP.

Families of very Ancient and Unknown Origin and World-wide Distribu-
tion, and Isolated Autochthonous Families of Eogaic Origin.
CiYcinariidce. Northern South America and temperate North America.
Bulimulidce. Autochthonous ; formerly spread to Australasia and now

invading North America.
Strophocheilidcz. Autochthonous.
Endodontidce. World-wide, on all continents and islands.

1 Primitive Zonitida were probably evolved at a very early time, but the group attained its main
development in the Caenogaeic faunas.

614 PATAGONIAN EXPEDITIONS I ZOOLOGY.

Succineidce. World-wide, on all continents and islands.
Chilinidce. Autochthonous.
Amnicolidce. On all continents.

The ancestral stocks of these families probably formed the earliest
fauna of non-marine mollusks in South America. Some of the families
are known, in other regions, to have been established in Palaeozoic times ;
and it is likely that as early as that they were already found in South
America. All of them are sharply isolated groups.

The Circinariidce seem to have remote affinity to Rhytididce and Strep-
taxidce — both of which evolved in the southern hemisphere of the Old
World. In North America this family is probably intrusive, being repre-
sented by a single genus also found in South America.

The Strophocheilidce have relations — though not close — with a series
of genera (Acavidce] now found in south Africa, Madagascar, the Sey-
chelles, Ceylon, Moluccas, Australia and Tasmania. The radiation of
this scattered group from the Palaeozoic Gondwana continent of Neumayr
seems a reasonable, in fact the only tenable, hypothesis.

The BulfmuKda have descended from the Holopod stock, probably
also of Gondwana Land, since we have no evidence of any other ancestry.

Endodontidce and Succineidce are world-wide groups, even on the most
remote islands. Their early presence in South America is therefore likely.

The Chilinidce represent an isolated branch of the primitive Basomma-
tophora. No scrap of evidence has been brought to light to show that
they ever existed elsewhere than in South America ; and at present we
have every reason to believe that there they invaded fresh water from
the sea.

The Pectinidens group of Lymnceidce and the Ancylidce are evidently
traceable to some very early radiation. Adequate data upon the soft
anatomy and relationships of the forms of the southern hemisphere do not
now exist.

II. THE ARCHHELENIC GROUP.

Families which for the Greater Part are Represented in the

Tropical African Fauna by afar Greater Diversity of

Forms than in the South American.

The hypothesis of an Africo-Brazilian continent of Palaeozoic and Meso-
zoic times, first sketched out on purely palasontological grounds, and ably

PILSBRY: NON-MARINE MOLLUSCA OF PATAGONIA. 615

advocated by Dr. von Ihering from the evidence of the fresh-water fauna,
is essential to any rational explanation of the distribution of land and
fresh-water mollusks.

The following South American groups are common to the tropical
African radiation center. Terrestrial groups are marked with an asterisk (*).

* Streptaxidce (fig. 21).'
*• Ackatinufo (fig. 20).

* Veronicellidce.

Planorbince (South American Planorbis and Plesiophysa close to African

Planorbis and Isidord].

Ampullariidce (genera with corneous opercula, fig. 22).
Melaniidce (nearest to African forms).
Mzttelidce (fig. 23).
Etheriidce (fig. 24).
Sphceriidce, of the genus Eupera.

Such of these groups as are represented in the West Indies and sub-
tropical North America, have evidently, from their distribution, relation-
ships and the greatly diminished number of genera and species, been
derived from South America, rather than from some common source, such
as Archhelenis. None of them are present as Mesozoic or Tertiary
fossils in North America, x and nearly all of them are likewise absent from
European deposits.

There is a good deal of evidence that most of the above groups arose
in the eastern hemisphere and migrated westward, and little evidence or
none that any of them moved in the opposite direction.

The Streptaxidce, Achatinidce^ Ampullariidce^ Melaniidcz and Mutelidce
are far more diversified in Africa than in South America. It seems that
several Gondwana subfamilies were not present in the fauna of Archhelenis,
or at least did not extend so far west as to reach South America, though
they must date back at least as far as some other subfamilies which are
represented both in South America and Africa.

The primitive stock of fresh-water mussels seems to have early split into
two phyla : the one, Mutelidce, evolving in the south, on the Gondwana-
Archhelenis continent, the other, Unionidce, in the north, in North America

1 The Planorbincs are found on all continents, but those of South America are obviously most
closely related to the African forms.

and Asia. The occurrence of both families in the same waters is evidently
due to migrations, which ensued after the families had become differ-
entiated. The M^ltelid(Z attain their northernmost point in the Panuco
River, in northeastern Mexico, where the family is represented by one
species of the South American genus Anodontites.

Simpson and Germain refer a few African forms to the South American
genus Diplodon, and Germain has called attention to the similarity of the
African Pseudamcula to the South American Prisodon or Hyria. If the
resemblance of the shells proves to be supported by the soft anatomy,
then this family at least will be evidence of an eastward migration in
Archhelenis. At present the evidence is insufficient. The possibility of
convergence in shell-form must be taken into account. Most if not all
African Unionidce, like the African Cyclostomatidce, Zonitidce, etc., are
clearly of Oriental derivation. These are northern Caenogaeic families
which have invaded Africa during the Tertiary.

groups.

of molluscan distribution favor the view that in Archhelenic times the

were laid down ; eastern Brazil north to Guiana bounding this gulf on the
east, until the depression of the Atlantic basin marked the close of Mesozoic

620 PATAGONIAN EXPEDITIONS I ZOOLOGY.

time. Such a hypothesis finds support in the presence of genera of the
old Brazilian type on the island of Fernando Noronha. Numerous very
peculiar land-shell genera, such as those tabulated in fig. 25, have a dis-
tribution not readily explicable on any other hypothesis ; while in still
other cases, allied but generically distinct groups are similarly distributed.
It may be noted that Bates has remarked that the Para insect fauna is
essentially Guianian.1

Figs. 26, 27 show the distribution of several old land-snail genera of
the Brazilian center. Fig. 25 that of several genera common to the
Brazilian and Guianian centers.

That the Amazonian valley ever formed an upper Cretaceous strait
connecting the south Atlantic and Pacific, as claimed by Dr. Ortmann,2
seems rather improbable.

The Guiana-Colombian elevation has been a secondary radiation center for
a number of genera of autochthonous South American families, chiefly the
Bulimulidcz, The arboreal groups Oxystyla and Corona have spread south
of the Amazon into eastern Brazil (fig. 28), while numerous other genera
from this center are restricted to the north and west as in fig. 29. The
Guiana-Colombian area also served as a secondary center for Antillean
and Mexican groups, entering by way of the Caribbean elevation and that
in the Panamic region. These groups have spread southward as in

figs. 30-34-

A hypothesis has been advanced by Dr. Ortmann3 that Archhelenis of
the Lower Cretaceous was succeeded in the Upper Cretaceous by a land
bridge from tropical Africa to an area covering Guiana, the Caribbean Sea
and the Mexico-Antillean region (the so-called Mesozonia), separated from
the Brazilian island. By this hypothesis, Antillia should be as rich in
African or Archhelenic types as Brazil, and in fact should show a closer
resemblance to the African fauna due to the later connection. This is

2 Proc. Amer. Philos. Soc., XLI, p. 381, and in later articles. Dr. Ortmann's palaeogeographic
maps incline strongly towards what Fiske would call the "wet theory." It is not likely that all
beds reported as Upper Cretaceous were below the sea at any one time. To map an Upper Cre-
taceous epicontinental sea to include all the exposures of a formation which included so long a
period of time is not warranted by our present slight knowledge of the stages of the South
American Cretaceous.

exactly contrary to the actual facts of molluscan distribution. All African or
Archhelenic forms which exist in the Antilles are unequivocally of the South
American type, and certainly indicate that there was no later migration
or communication from Africa in the north. There seems little evidence

1 The belogonous and epiphallogonous Helicidce of South America are clearly of northern
origin. Whether such extremely peculiar genera as Solaropsis, Psadara and Macrocydis also
belong in the same category, seems somewhat uncertain, although such competent malacologists
as von Ihering and Fritz Wiegmann place these genera in the Epiphallogona.

The heavy, large Helices of the Eocene of southern Europe, such as Deutellocaracolus, Pro-
thelidomus, Galactocheilus and Fridolinia, may perhaps belong to the group Epiphallogona of my
arrangement, rather than to the Helicinae where I formerly placed them ; yet if so, I think the
supposed relationship to West Indian forms is not especially close. Like the American and
European species of Adelopoma, the Epiphallogona probably reached both Europe and America
from eastern Asia, and from opposite directions.

Dr. von Ihering (Verhandlungen k. k. zoologisch-botanischen Gesellschaft in Wien, LIX,
1909, pp. 420-428) has recently referred the belogonous Helices (Epiphragmophora) of Argen-
tina and southern Brazil to the European genus Helicigona (Campyltea auct.) ; but I do not
believe that this classification can be sustained. So far as I know, the South American Epiphrag-
mophoras have the spermathecal duct very short, whereas Helicigona, like all other European
Belogona, has a very long duct, bearing a long diverticulum, which is bound by a membrane to
the oviduct. These are important differences, quite sufficient to show that Epiphragmophora is
not at all closely related to Helicigona, aside from the different shape of the mucous glands, and
their removal in Epiphragmophora from the vagina, upon which they are invariably inserted in all
European Belogonous Helicidce,

By its short spermatheca, Epiphragmophora differs strongly from all other known belogonous
Helicidce. In other features it stands nearer to Antillean and North American forms than to
European. My former treatment of the genus was too inclusive. I would now restrict Epiphrag-
mophora to forms having the spermatheca short, removing all of the Mexican and North Amer-
ican species (which have a long spermathecal duct) from the genus.

the Caribbean Islands on the east, and on the west the region of the Isthmus
of Panama, where the interchange of forms has continued to the present
time. That the middle American elements are far younger in South
America than the Archhelenic, is shown by their close relationships to
Antillean and Mexican forms, very few special genera having evolved. In

most of the families only one or very few genera have invaded South
America out of a large number in the parent lands. Moreover, it is notable
that they have not extended far south in the east, where the Amazon
valley has proved a barrier to land-snails. Their distribution has been
along the Andes, spreading eastward in Bolivia and southern Brazil.

of land-snails incursive in South America.

624

PATAGONIAN EXPEDITIONS: ZOOLOGY.

In molluscan distribution, there is strong evidence against the view
of Ortmann (1902, p. 347) that the northern margin of South America
formed part of the Antillean continent. Schuchert's representation of the
Caribbean Sea as an old permanent basin seems preferable ; but his repre-
sentation of the total submergence of the Antilles in the Middle Cretaceous

and again in the Upper Oligocene1 cannot, I think, be sustained. The
rich Oligocene beds of Jamaica (Bowden) and Santo Domingo, carrying
a marine fauna of littoral type, occur at very low levels ; and no deposits
actually known to be Oligocene are found on the higher mountains, which
I believe were islands in both Cretaceous and Oligocene times.

The primary region of radiation of the middle American families named
above is a subject too large for adequate discussion in this place. So
much is clear : the fauna contains three groups of diverse genesis. The

Cyclostomatidce, Helicinidce, contains many phylogerontic lines, signalized
by shells with more or less detached or uncoiled later whorls, sculptured
embryonic whorls, highly developed, often spinose sculpture, complicated
internal armature, and the like. These first families of Antillia, now in their
old age, are related to the families of the northern or Caenogaeic area of
land-mollusk evolution. Some of them, and the ancestors of all, doubtless
had a much wider range in Mesozoic times. A few, such as the Oleacin-

idee and Cyclostomatidcs, were abundantly developed in Europe as late as
the Miocene, or even linger in a few forms in the recent fauna. These
European forms cannot, in my opinion, be looked upon as ancestral to the
Antillean, but rather as parallel descendants of a common stock derived
from the north, where the old Scandinavian and North American land
areas were, at least from time to time, united.

A second element of the Mid-American lands consists of groups derived
from the Chinese or east-Asiatic center. Prominent members are the

626 PATAGONIAN EXPEDITIONS I ZOOLOGY.

lommatinidce (Adelopoma], Clausiliidce, etc. These forms never have the
old-age stigmata of the preceding group. They are developed in won-
derful abundance and virility. Being known in characteristic genera of
American type (Pleurodonte, Cepolis] in the Floridian Oligocene island, the
advent of the group in middle America must have been much earlier. It
could hardly have been later than the beginning of the Eocene, and prob-
ably was not later than the Upper Cretaceous.1

Finally, we have as the latest faunal element in the Antillean-Mexican
area, a series of South American forms — Achatinidce, Bulimulidce,
Ampullariidce, Melaniidcz, Mutelidce and some North American forms,
Unionidce, Pupillida, Zonitidce, Polygyrince, etc. These are, with very few
exceptions, unchanged generically, and some are specifically identical with
existing South or North American forms. It is very evident that such
Archhelenic forms as exist in the Antilles and Mexico were not derived
directly from the Archhelenic area ; they migrated in the later Tertiary
and Pleistocene from the Guiana-Colombian center.

Antillia has not been an evolution center for fresh-water mollusks or
fishes, evidently because it has never been a very large area, and has been
an unstable one, at one time in form of a continent, again an archipelago,
hence without river systems of great extent or duration, such as are essen-
tial to the evolution of a fresh-water fauna.

There is absolutely nothing in the distribution of mollusks suggesting
that either South or North America was at any time connected with the
supposed South Pacific continent, or the Hawaiian group. Even Juan
Fernandez has a land-snail fauna of Pacific and not South American type.
The Hawaiian and Polynesian connections with America mapped by Arldt
(1907) seem quite impossible.

1 The American Clausiliidcz are thought by Professor Boettger to be related to the European
Miocene and recent Pyrenean group Laminifera, but they seem to me even closer to the genus
Garnieria, of the Indo-Chinese center. The Helicinidce may have arisen in Middle America from
an aquatic rhipidoglossate stock, but the very wide distribution of the group in Polynesia and
eastern Asia suggests that it is a very old one, which probably appeared among the first land-
snails.

The Belogonous Helices still exist in high latitudes on both sides of the Pacific, being known
from Sitka on the American and the Kuril Islands on the Asiatic side.

PILSBRY: NON-MARINE MOLLUSCA OF PATAGONIA. 627

ARCHIPLATA AS AN EVOLUTION-CENTER.

Wallace in I8761 showed that the South American fauna is divisible
into two subregions which he called the Tropical or Brazilian and the
South Temperate or Chilian. He calls attention to the affinities of the
Chilian diurnal Lepidoptera and the Carabidae to North Temperate forms.2
Dr. H. von Ihering in numerous papers 3 has recognized the two subregions
of Wallace as distinct evolution centers. He concludes that these centers,
Archiplata (that is, Patagonia, southern Brazil, Chili and western Peru) and
Archibrazil, were long isolated from one another by an arm of the sea. As
primitive elements of the Archiplatan fauna he mentions the fresh-water
crab sEglea, the genus Parastacus, and the mollusks Diplodon and Chilina.
Negative characteristics are found in the absence of the dominant Ama-
zonian genera of mussels and Ampullariidcz (which seem to have invaded
the La Plata drainage area comparatively lately, probably in the Pliocene)
to which many groups of land-snails might be added.

The geology of the regions involved is so imperfectly known that we
have no positive data for or against the hypothesis that an arm of the
Cretaceous sea extended across the continent, as von Ihering claims. This
is a question only to be settled by geological exploration of the region,
which may perhaps show a Cretaceous transgression similar to that which
involved eastern Mexico and the region northward in the middle Cretaceous.
Yet the fact remains that, so far as molluscan groups are concerned, there is
but little evidence of such an isolation of the Archiplatan area. The barriers
to migration imposed by climate have not been taken into account. The
AmpitllariidcB are snails that have never, in any region, been able to extend
beyond a subtropical climate. TheGb&Kttfe (fig. 36) are apparently, like
the large Lymnaeas in North America, snails which cannot exist in a sub-
tropical or even a warm temperate environment, however favorable maybe
the conditions of migration. It is instructive, in this connection, to com-
pare the Lymnaeid faunas of Minnesota and Arkansas, which show great

1 Geographical Distribution of Animals, II, frontispiece and Chapter XIV.

1 Dr. Scharff has suggested an explanation of this peculiarity (American Naturalist, Septem-
ber, 1909, p. 5 13), but his hypothesis explains only a few facts. It would involve us in problems
more intricate than those which it solves. Possibly the systematic relations of the insects in
question have not been rightly estimated.

notis," Leipzig, 1907.

diversity, although favorably situated for migration. 1 Another group which
is widely distributed in the Archiplatan area, though not confined to it, is
the Amnicolid genus Littoridina (fig. 35). The absence of Amnicolidae
in the Amazon system is probably apparent rather than real, since prac-
tically no collecting of small or minute mollusks of any kind has been
done in that vast area. It is likely that Amnicolidae will be found there

in abundance. Diplodon, another genus which Dr. von Ihering considers
Archiplatan, is found almost all over the continent, and cannot fairly
becl aimed as of Archiplatan origin. It no doubt arose from the same
Brazilian (and ultimately Archhelenic) stock as Hyria, etc.; but like Unio
in the northern hemisphere, it is a hardy stock not highly evolved in its
phylum, hence probably old. Compare in this connection the Unionid
and Pleuroceratid fauna of Alabama with that of Georgia and the Caro-
linas. In these adjacent areas, which have been continuous land since
very early times, we have as much difference in the fresh-water faunas as
has been shown to exist between Archibrazil and Archiplata. Rich faunas
of fresh-water mussels and gastropods are rarely found in regions like

Minnesota, but the species has not been able to gain a place in this fauna there or farther south ;

southern South America, drained by numerous short, independent rivers,
owing to the difficulty of migration and the relative impermanence of the
individual streams.

The presence of peculiar and strongly individualized land snails of
Brazilian type (Scalarinella, Plagiodontes, etc.) in the Sierras of western
Argentina and the now isolated Sierra Ventana, shows that long ago the
Brazilian fauna extended at least as far south as Bahia Blanca, where a
fragment has persisted, isolated since the Pliocene at least.1

Taking into consideration the climate, the rarity of large forest areas,
the aridity of large tracts, and the short, unconnected rivers, we are not
inclined to give much weight to Dr. von Ihering's contention that many
Brazilian groups are wanting in " Archiplata." So far as mollusks are
concerned, that area has very slight claims to rank as an evolution center.
I regard the Chilian and Patagonian fauna as an impoverished and slightly
modified extension of the fauna of the old Brazilian continent. The evi-
dence for an Archiplatan center may be stronger in the case of Crustacea,
Oligochaeta, plants and insects ; but I prefer to leave the discussion of
these groups to those having first-hand knowledge of them.

Connected with the Archiplata hypothesis is that of Antarctica, which
may here be examined briefly.

AUSTRAL ELEMENTS IN THE SOUTH AMERICAN

FAUNA.

The Austral or Antarctic relationships of the South American fauna
have been somewhat fully discussed in other volumes of this series, and
a map illustrating the Antarctic continent and its hypothetical former ex-
tensions may be found in volume IV. I have to deal here with the evi-
dence afforded by the non-marine mollusks, which, taken by itself, leads to
the following conclusions : ( i ) There is no evidence that Antarctica was
ever an evolution or radiation center for non-marine mollusks, though
there is some evidence showing that it served as a highway for migration.

(2) There is some evidence of migration from South America to Austral-
asia, but at present no evidence of a counter movement to South America.

(3) Nothing in the distribution of mollusks would lead to the hypothesis

1 Dr. Ortmann agrees with von Ihering in isolating a Chilian and southern Patagonian land
mass of Cretaceous age, but he views it as an extension of Antarctica. The difference is rather
one of names than of things. Proc. Amer. Philos. Soc., 1902, pp. 379, 381.

630 PATAGONIAN EXPEDITIONS! ZOOLOGY.

that South Africa has ever been connected with Antarctica and thereby
indirectly with southern South America.

Non-marine mollusks having an Antarctic distribution belong to three
families. The evidence in each case is briefly as follows :

i. The Bulimulidce, land snails of South American origin, of which one
genus (Bothriembrion) is found in Tasmania and southwestern Australia,
another (Placostylus] in New Zealand, New Caledonia, the islands of
Melanesia and as far east as Fiji. Both of these genera are distinct from
South American forms, but they are undoubtedly related to the more
generalized of the South American genera.

FIG. 37.

Distribution of the land snail family Bulimulidae. The number of genera in each area is indi-
cated by figures.

The presence of Bulimulidce in Australia and Melanesia proves that
the part of South America connecting with Antarctica was, or had been,
connected with the old Brazilian evolution center.

2. The Amnicolidce, a family of fresh-water snails, has one genus,
Potamopyrgus, in New Zealand, Tasmania and South America. Another
South American genus, Pofamoltikus, has its nearest ally in the genus
Petterdiana of Tasmania and Australia. Both of these genera are exclu-
sively fresh-water groups. See pp. 548-550 of this report.

PILSBRY: NON-MARINE MOLLUSCA OF PATAGONIA. 631

3. The Naiades or fresh-water mussels found in all of the continents, are
represented in Australia, Tasmania and New Zealand only by species
which have been referred to the genus Diplodon. This genus is widely
distributed in South America, especially southward. It is a relatively
primitive genus and probably arose in South America, which, from the
number of autochthonous genera, was evidently an old evolution center
of Naiades. Diplodon is unknown in the northern continents. Whether
the relationship with South American forms claimed for the Australia-
New Zealand group is well-founded, remains to be confirmed by careful
comparison of the soft anatomy.

The family Endodontidce, and Gundlachia of the Ancylidce, have been
considered "Antarctic" groups, but on evidence of slight value. The
Endodontidce are an ancient group, world-wide in distribution. No close
relationship has been shown to exist between the South American and
the Australian genera. The former are unknown anatomically, and the
relations of Australian and New Zealand forms, so far as positively made
out, are with the groups of Polynesia and Micronesia (Charopa, Thattma-
todon, etc.). Certain Tasmanian species may prove to belong to the
American genus Radiodiscus Pils. See p. 516.

Gundlachia is found in Australasia, South America, the Antilles, Mexico,
temperate North America and also the Miocene of central Europe. This
wide distribution suggests that the genus may have reached the southern
lands from the north. In the United States it has been found in Cali-
fornia, Illinois, Ohio, New York, etc., but only at remote intervals and in
very narrowly restricted areas. It is likely that it will turn up sooner or
later in the Oriental region and Africa. I hesitate to claim Gundlachia
as an inhabitant of Antarctica.

Pond snails of the family Lymnceidce also occur in all the Austral
lands, but South American forms do not seem especially related to Austral-
asian. While Endodontidce, Gundlachia and Lymncea may have inhabited
Antarctica, no data upon them now in our possession goes far towards
proving that they did.

I can find no evidence to support Hedley's contention that the Macro-
ogona (Acamdce] of Tasmania and Australia, and the Rhytididce of the
same regions, New Zealand, New Caledonia, etc., are "of Antarctic origin."1
These groups must have attained their distribution from South Africa to

1 Hedley, Proc. Linn. Soc. N. S. Wales, 1899, pp. 396, 398.

632

PATAGONIAN EXPEDITIONS: ZOOLOGY.

Australia by way of the Gondwana continent, leaving isolated genera by
the way in Madagascar, the Seychelles, Ceylon and the Moluccas. To
this Palaeozoic and early Mesozoic land the South African Endodontidce,
Peripatus, etc., may also belong. The evidence for an isthmus connecting
South Africa and Antarctica, as sketched by Forbes, Ortmann and some
other palaeogeographers, seems unsubstantial. Nothing in the distribution
of non-marine mollusks lends it support.

Showing sources of the South and Middle American mollusk faunas. Early Mesozoic and
earlier migrations in heavy lines, late Mesozoic lighter lines, Tertiary and later migrations in dotted

The rather large size of the fresh-water mussels and Bulimulidce pre-
cludes the idea of their distribution as adult organisms except by actual
land connection. Some embryonic Unionidce are probably carried by water
birds, but we do not know that this is the case with Diplodon; moreover
only short distances can be so traversed, since unionid embryos are known
to die quickly out of water. It is hardly conceivable that Bulimulid eggs,
which are smooth and not viscid, should be so carried. The same is true

PILSBRY: NON-MARINE MOLLUSCA OF PATAGONIA. 633

of the egg-capsules of Amnicolidcz. It would be absurd to suppose that
they could ever be spread by aquatic birds.

Such evidence as we have favors the view that the connection of South
America with Antarctica was transitory, hence taken advantage of by but
few genera of mollusks, all belonging to families richly developed in the
South American center. So far as non-marine mollusks show, the migra-
tion from South America of a few species belonging to three families will
account for all the common elements in the austral lands of the two
hemispheres. The strong generic differentiation of all the common
austral groups, with the exception of Potamopyrgus and probably Diplo-
don, indicates that the connection was of considerable antiquity, probably,
as Dr. Ortmann holds, not later than Eocene.

Summary. — The South American molluscan fauna is traceable to two
sources : an ancient southern continent lying across the south Atlantic
and enduring from at least Palaeozoic to near the end of Cretaceous time,
and to Miocene and Pliocene to recent connections with the middle
American area. Antarctica was not an evolution center for mollusks, but
there is strong evidence that a few groups passed by the Antarctic route
to Australasia. " Archiplata," owing to its physical diversity from the
Brazilian and Colombian areas, has became a Tertiary evolution center
for a few groups of Brazilian origin.

Middle America (Antilles + Central America and part of Mexico) has
the characteristics of an old evolution center of the northern faunal
group, its primitive fauna coming from the north, and now showing phylo-
gerontic features ; a later (probably late Cretaceous) element was derived
from the East Asiatic fauna. Both elements contributed, during the last
half of the Tertiary, to the South American fauna, and received immi-
grants in return.

The " Nearctic Realm," so far as the genesis of its faunas is concerned,
is composite.

LETTER OF TRANSMITTAL.

Sir :

I have the honor to transmit herewith the report on the recent Crus-
tacea collected in Patagonia by Mr. J. B. Hatcher.

The collection is a small one, and contains, of marine forms, only such
as are more or less well known, adding, however, for some of them new
localities on the eastern coast of Patagonia, a region that scarcely has been
properly investigated.

The most valuable part of the collection consists of freshwater Crus-
taceans found by Mr. Hatcher in the interior of southern Patagonia : among
them are several very important new and rare species.

Very respectfully, your obedient servant,

INTRODUCTION.

The collections of Crustaceans made by Mr. J. B. Hatcher in southern
Patagonia are partly marine, partly freshwater. The following are locali-
ties from which marine forms have been secured : they are all close to the
shore, in shallow water, and are situated — with the exception of the first
— on the eastern coast of Patagonia.

2. Gallegos, at the mouth of the Gallegos River, South Patagonia.

3. Cape Fairweather, entrance of Gallegos Bay, northern side.

4. Mount of Observation, about 50 miles southwest of Santa Cruz.

5. Mouth of Santa Cruz River, situated at about 50° S.

6. San Julian, about 50 miles northeast of Santa Cruz.

Freshwater material has been collected at numerous localities in the
interior. This has been numbered by Mr. Hatcher according to stations,
and the character and description of each station is given in the text
under each species. All these stations are situated in the region of the
Rio Chico (northern tributary of the Santa Cruz River), from near the ocean
up to the foothills of the Cordilleras, in 47-50° S. The localities Sierra
Oveja and Sierra Ventana are on the Rio Chico. Arroyo Gio is in the
foothills of the Cordilleras.1 The highest altitude at which specimens
were obtained is at about 2,000 feet.

The original genus Boeckella of Guerne and Richard (1889, p. 151),
created for the preoccupied Boeckia of Thomson (1883) was divided by
Mrazek (1901) and von Daday (1902) into several genera. Of course,
Mrazek's names have the priority. Unfortunately both divisions do not
completely agree, and the names chosen by either author are apt to give
origin to confusion. Generally, we may say that Pseudoboeckella of
Mrazek corresponds to Boeckella of v. Daday, and vice versa, although
Mrazek puts B. bergi Rich, into a separate genus (Boeckellopsis], while it
is included in v. Daday's Pseudoboeckella; and although B. brevicauda
Brad., which is included in v. Daday's Boeckella, forms the genus Para-

The two species mentioned here have been described by v. Daday under

Description. — Scutum large, suboval, emarginate behind, covering about
two thirds of the body. Of the abdomen, 9 or 10 segments (including
telson) are uncovered. Eyes elliptic, closely approaching one another in

front, diverging behind. First cervical furrow almost straight, second one
strongly curved backward in the middle, and slightly shallower in the
middle, but distinct. Median keel indistinct anteriorly, very distinct pos-
teriorly. Lateral margins smooth, only near the posterior corners, for a
short distance, very finely crenulated. Posterior emargination with small,
somewhat irregular spinules, the median one (end of median keel) the
largest. Supra-antennal keel slightly sinuate, apparently smooth, but
under the lens there are fine and minute granulations.

Flagella of first pair of feet short, unequal, slightly depressing the margins
of the scutum. Free abdominal segments spinulose, about 6-8 spinules
on upper side ; these are larger, straight, and arranged somewhat irregu-
larly ; those of the ventral side are smaller, numerous.

Telson (fig. ib] on upper side, near base of cercopoda, on either side
with a small, spinulose tubercle. Caudal flap elongate, over twice as long
as wide at the base, with parallel margins, sublanceolate at the end and
rounded ; distal half of margin spinulose, with the strongest spinule at
the end. Upper surface with a median, longitudinal keel bearing four
strong spinules.

Cercopoda almost as long as the rest of the body, thickly covered with
bristles.

Color deep green, lower parts pale greenish, mandibles brownish.

Size : Length of body 40 and 46 mm. Total length of larger indi-
vidual (including cercopoda), 77 mm.

Remarks. — At first there seemed to be no doubt to me that our speci-
mens ought to be referred to L. patagonicus Berg (1900), which comes
from near the same region (Territ. of Chubut), but a careful comparison
of our specimens with Berg's description reveals the following dis-
crepancies :

1. Of the abdomen, only 10 segments are exposed in our species, while
in L. patagonicus 15-16 are seen. Thus the abdomen of the latter appears
to be longer.

2. In L. patagonicus the eyes are said to be suboval, and not to approach
one another anteriorly, while in our species they are elliptic and distinctly
convergent in front.

3. The lamina caudalis, in L. patagonicus, is one third longer than
broad ; in our species it is distinctly more than twice as long as broad.
This is the most striking difference. Through the kindness of Mr. A. J.

642 PATAGONIAN EXPEDITIONS I ZOOLOGY.

Pendola of the museum in Buenos Aires, I possess sketches of the caudal
flap of Berg's species, which show that it is only very slightly longer than
broad.

4. There seems to be more of a ferrugineous color on the lower side
of the body in L. patagonicus.

5. The size of L. patagonicus is smaller, body 30-35 mm., and includ-
ing cercopoda, 43-46 mm., while our species, without cercopoda, reaches
46 mm.

Berg describes a male, while our specimens are females, but I hardly
believe that the above differences are due to sex, since it is characteristic
in this family that $ and 9 hardly differ, except for the smaller size of
the J1, and the larger caudal flap of the tf. While the first character
would apply to this case, the second does not, the caudal flap being much
larger in our 9- On the other hand, the longer abdomen in the J1 would
agree with the same condition found in the J1 of L. bilobatus.

For the rest, our species resembles L. angasi Baird (1866, p. 122, pi.
12, f. i) from South Australia (Adelaide). Here the general form of the
body and the characters of the various parts are almost identical, and I
find only the following differences :

1. L. angasi is much smaller (i inch = 25 mm.).

2. The body is of horn-color instead of green.

3. The spinules of the abdomen are curved downward in L. angasi,
while they are straight in our species.

In all other respects, both species are closely allied, especially the fol-
lowing important characters agree :

1. Number of exposed abdominal segments : 12 in L. angasi (accord-
ing to figure), 10 in our species.

2. Eyes of the same size and shape (according to figure of L. angasi}.

3. Keel of scutum, and fine dentations on posterior part of lateral
margins similar in both.

4. Cervical furrows identical (according to figure of L. angasi}.

5. Caudal flap absolutely identical in form, but it seems that the margins
are denticulated all around in L. angasi.

The apparently close affinity of our species with the South Australian
L. angasi demands an investigation of the relationship of it with the other
known species of the genus, and we may state the following :

i. L. glacialis (Kr.) (see Simon, 1886). Arctic regions.

ORTMANN: CRUSTACEA OF SOUTHERN PATAGONIA. 643

For a comparison with our species this is out of the question, on ac-
count of the short flagella of the first legs, and the very short caudal flap.

2. L. lubbocki (Brauer), from Sicily and Algiers, and L. macrurus Lilj.
from Archangel, Russia (see Simon, 1886), have a carina of the scutum
that is sharp from its beginning at the second cervical furrow down to the
hind margin. These two species are closely allied to L. apus (L.) from
Europe (see below), which is in some degree related to our species, but
just in the character mentioned here they deviate more considerably from
L. hatcheri, than L. apus does.

3. Of the North American species (see Packard, 1883), L. bilobatus
Pack, from Colorado is entirely different in the bilobate caudal flap and the
longer abdomen (12 segments exposed in the cT, 16 in the $). L. couesi
Pack, from Montana and Utah differs in the much shorter abdomen, and
the longer and distinctly spatulate caudal flap. L.packardi Simon (1886,
p. 448) from California differs at once in the very short abdomen, in the
second cervical furrow, which is interrupted in the middle, and in the
median keel of the caudal flap, which has 7-8 spines.

4. Of the other Australian species (aside from L. angasi], L. viridis
Baird (1850, p. 254, pi. 17, f. i) from Tasmania has a distinct carina of
the scutum, and the caudal flap is oval (narrower at the base). L. mridu-
lus Tate (1876, p. 136, and Brady, 1886, page 88, textfig. E) from Ade-
laide has the abdomen very short, and the caudal flap is distinctly spatu-
late.

5. The two New Zealand species, L. kirki and compressus Thomson
(1879, p. 260, pi. n, f. 4, 5) are also distinctly different: in L. kirki a.
much larger part of the abdomen is covered, and, although the caudal
flap resembles somewhat that of L. hatcheri, it is shorter. L. compressus
is entirely different in the shape of the scutum, which is oval and narrow,
keeled only posteriorly ; the caudal flap is much shorter and the margin
of the scutum is smooth.

Thus there only remain for comparison L. apus from central and
northern Europe, and L. angasi from South Australia. Of these, L. apus
(L.) resembles our species in general form, length of abdomen (8 exposed
segments), in the character of the carina of the scutum; but it differs:

1. In the second cervical furrow, which is interrupted in the middle.

2. In the caudal flap, which is oval, narrower at the base, and about
twice as long as wide.

644 PATAGONIAN EXPEDITIONS I ZOOLOGY.

3. In the eyes, which are said to be reniform.

L. angasi is still more closely allied to L. hatcheri, as has been demon-
strated above, especially the caudal flap is almost identical. This close
relation of these two species is especially interesting from a zoogeographi-
cal point of view.

Description. — Allied to B. coloradense Packard ( 1 883, p. 338, textfig.
19) from Colorado and (according to Lilljeborg) Fresno, California, and
still more closely to B. iheringi Lilljeborg (1891, p. 424, and v. Ihering,
1895, p. 178) from Rio Grande do Sul, Brazil.

The chief differences are found in the male claspers (second antennae)
(fig. 2), which are very robust and long (extended, almost as long as the
anterior portion of the body). Basal joint subcylindrical, slightly curved,
with a distinct tubercle (knob) at the base on inner side. Inner margin
in the distal half with a prominent crest, the edge of which is finely
dentate. The inner margin of first joint, between this crest and the basal
knob, is concave. Second joint almost as long as the first, compressed
and lamelliform, and a little narrower than the first joint, with nearly
parallel margins ; slightly concave on under side (if this joint is stretched
out, the concave side is the outer side), curved, and near apex strongly
bent, where the margins form a distinct lobe on each side, rendering the
end of the second joint trilobate, the middle lobe being strongly deflected
from the general plane.

ORTMANN: CRUSTACEA OF SOUTHERN PATAGONIA. 645

In the female the claspers are very short, stout, straight, slightly taper-
ing and suddenly truncated at the end, with the outer margin produced
into a short spine. Ovisac very long, two thirds as long as the abdomen,
reaching to the penultimate abdominal segment ; its end pointed.

Caudal appendages, in both sexes, rather long, about twice as long as
the terminal segment.

Length of body (in male and female), about 15 mm.

Remarks. — I had drawn up the above description, before I became
acquainted with vop Daday's paper. After having seen the latter, I was
at once convinced that our specimens belong to this species, although my
description does not agree completely with that given by von Daday,
But this seems to be due to a different interpretation we have given to
the microscopic image, and after a renewed examination, I do not see
any reason why I should alter my original account.

The description of B. ikermgt, given by Lilljeborg, applies in some de-
gree, as far as it goes, to our species. Lilljeborg says that there are a few
small spinules on the inner side of the first joint of the male claspers, and
that the second joint has, at the apex, a tubercle on the posterior margin,
and a tuberosity on the anterior side. While this structure appears to be
similar to that found in our species, the spinules of the first joint are, in
the latter, represented rather by a denticulate crest, and, further, Lilljeborg
does not mention the peculiar laminate form of the second joint, which, in
our species, has no tubercles or tuberosities at the apex, but rather lamel-
liform lobes. (The peculiar shape of this joint is, in my opinion, not quite
correctly understood by von Daday.) Finally B. iheringi is smaller than
our species, only 8 mm. the 9, 1 1 mm. the $ , while B. granulosa attains,
according to our material, 15 mm., and according to von Daday 15-18
mm. Thus B. granulosa seems to be different from B. iheringi, although
closely allied to it.

keeps both sets separate, and calls the first by the name of S. gigas, the second by that of 5.
lanceolatum, but he does not give any characters, so that it is impossible to decide, whether his
5. lanceolatum is really that of White.

Shallow water. This species also has been reported from New Zealand,

Remarks. — Our largest individuals attain the length of about 25 mm.,
by a width of about 15 mm. They all agree in the essential characters,
and represent the typical form of E. gigas, as described and figured by
Stebbing, with the only exception that in Stebbing's figure of the whole
animal (pi. 39) the outer ramus of the uropods is broader than in our
individuals, in which it is distinctly narrower, the end being sometimes
subacute, sometimes rounded. In this respect, our specimens correspond
better with the figure given by Dollfus, yet Dollfus says that there are
variations in this respect.

Localities. — Mouth of Santa Cruz River, i smooth, 14 sculptured speci-
mens ; San Julian, 3 smooth, 2 sculptured specimens.

Distribution. — Falkland Islands and Tierra del Fuego (region of Cape
Horn). Shallow water to 95 m.

Description. — This species differs from the foregoing in the following
particulars :

1. In the smaller size. While E. gigas attains 25 mm., Dollfus gives,
for this species, only 12 mm., and our largest is 14 mm. White gives
% to i inch (18-25 mm.), but these measurements apparently include
E. gigas.

2. In the epimera of the peraeon-segments, which are abruptly bent
down, so as to form a sharp angle with the middle of the back, which is
sometimes cariniform. This character is very important, and never found
in E. gigas.

3. In the sculpture of the posterior peraeon-segments, of the pleon and
telson. This sculpture varies considerably, but in E. gigas there is no
sculpture at all.

648 PATAGONIAN EXPEDITIONS: ZOOLOGY.

4. In the more narrowed apex of the telson, which may be called sub-
acute, and which is a little more produced than in E. gigas.

Remarks. — As regards the third character, given above, the original
description of White says that the last joint of the abdomen has, near the
base, a slight elevation, grooved in the middle. Stebbing says that there
is, on the telson of the specimen he is inclined to refer to this form, a longi-
tudinal groove between two elevations, and then a carina running to the
end. I have asked for further information from Mr. Stebbing, and, in a
letter, he kindly has furnished the additional character, that the last three
segments of the perseon have, along the hind margin of each, four small
tubercles.

Among our material, those specimens called the "smooth form," show
exactly the characters given by White and Stebbing : a low elevation on
the telson, divided by a groove, and an indistinct median keel running
backward, so that there is no doubt that they belong to White's S.
lanceolatum. I do not see, however, the four tubercles observed by
Stebbing on the peraeon-segments. The pleon and telson of these
individuals possess fine granulations.

As regards S. calcarea of Dollfus, the chief characters are, beside the
double keel in the anterior part of the telson, and the single median keel
in the posterior, the distinct and prominent granulations on the posterior
part of the body, chiefly on the telson. This character is strongly pro-
nounced, among our specimens, in those that have been called above the
"sculptured form." These granulations are somewhat irregular, and
assume sometimes an almost vermiculate appearance. This form also
shows the four little tubercles on the hind margins of the three posterior
peraeon-segments, observed by Stebbing. There is much variety in the
degree of development of the granulations.

The fact that Dollfus mentions a smooth form, and that these two
forms, the smooth and the sculptured, also have been found associated by
Mr. Hatcher at Santa Cruz and San Julian, while the typical E. gigas is
found not at all at these localities ; and further, the fact that among the
large number of E. gigas collected by Hatcher at Punta Arenas not a
single individual of these forms has been discovered, is much in favor of
the view that they really belong together, that is to say, to White's S.
lanceolatum. All our specimens from Santa Cruz and San Julian differ
in the same four characters, mentioned above, from S. gigas, and further,

ORTMANN: CRUSTACEA OF SOUTHERN PATAGONIA. 649

Mr. Stebbing informs me that Dollfus' 5. calcarea might very well be a
form of that, which he is inclined to take for White's S. lanceolatum.

The question remains, whether Dollfus was justified in calling his
species by the name of 5". calcarea Dana. Dana's species came from
Tierra del Fuego, but his description and figure (1852, p. 776, pi. 52, f. 2)
do not give any characters that warrant this identification, and considering
the adverse conditions by which Dana was hampered in the preparation
of his figures and diagnoses (see Stebbing, 1900, p. 528), we had better
disregard S. calcarea Dana altogether.

As regards the outer ramus of the uropods, which is given by White
as an additional distinctive character of S. lanceolatum, I cannot say that
it is very distinct from that of E. gigas. It is lanceolate, mostly rounded
at the apex, but sometimes subacute, and offers about the same shape and
variations as in E. gigas.

This species also belongs to the genus Exosphaeroma as defined by
Stebbing.

Distribution. — Although a new species, some previous references might
possibly belong to it. As we shall see below, a locality from which Faxon
mentions H. dentata inermis, may belong to this species, namely : Puerto
Bueno, Smyth Channel, Straits of Magellan. The same form, H. inermis
has been mentioned by Wierzejski (1892, p. 187) from a stream that issues
from a lagune near Mendoza (northern Argentina), the water of which has
an odor of sulphur. However, what this form really is, remains to be seen.

Cunningham (1871, p. 498, pi. 59, f. 14) mentions Allorchestes pata-
gonicus from a freshwater stream near Punta Arenas. He does not give
any description, since his single specimen was considerably injured, and
the figure is quite poor, and, no doubt, even incorrect. It is possible that
our species was intended, but we have no means of deciding this, and Al-
lorchestes patagonicits must remain a "nomen nudum."

Description. — Body rather robust, general form agreeing with that of//.
dentata inermis Sm. Eyes small, black, rounded, about twice their diam-
eter distant from one another.

Antennulae longer than the stalk of the antennae, a little more than
half as long as the whole of the antennae. First and second joint of
peduncle of the same length, third a little shorter. Flagellum with 10-12
joints in the tf, and with 8-10 joints in the 9.

Antennas about one third as long as the body, or even shorter. The
first joint of the peduncle short, the second a little longer, the third dis-
tinctly longer than the second. Flagellum with 12-17 joints in the tf,
and with 9- 1 4 joints in the 9.1

Maxillipeds (fig. 3, a) of the usual form, but all the joints are more
slender than in H. dentata inermis.

First gnathopod of the cT (fig- 3, &} '• Meropodite with a blunt promi-
nence on the inferior margin, which is beset with a number of setae. Car-
popodite about twice as long as meropodite (measured from the middle of
the articulation with meropodite to the middle of articulation with propo-
dite), upper margin with a sharp spine near the distal end, which has a
group of setae ; lower margin with a very prominent, lobiform, rounded
projection, the margin of which is fringed with stiff setae. Propodite
almost triangular, almost as wide as long, and about as long as carpopo-

number of joints of the flagella of both antennulae and antennae varies with age: it is
less in young individuals, greater in adults. Often the number differs on either side; this differ-
ence, however, is always slight, only amounting to one or two joints.

dite; palmar margin oblique, nearly straight, with several rows of setae, which
become spine-like at the outer end ; just below this end there is a group of
more numerous setae. There is no excavation to receive the tip of the
dactylus. Outer surface of palm with an oblique row of setae. Dactyr
lopodite slender, slightly curved.

First gnathopod of 9 (fig. 3, c] similar to that of the J1, but propodite less
distinctly triangular, and accordingly, less wide in proportion to length.

Second gnathopod of J1 (fig. 3, d}: meropodite with a triangular, pointed
prominence on the lower margin. Carpopodite about as long as mero-
podite, with a narrow, pointed prolongation of the lower margin, which
is longer than the width of the rest of the carpopodite. Palm (measured
along the upper border) about 4 times as long as carpopodite, triangular,
swollen, in general form very similar to that of H. dentata inermis.
Palmar margin oblique, very slightly sinuous, with a series of small spines ;
the lower (outer) end with a depression to receive the tip of the dactylo-
podite, and around this depression with 2-3 stronger spines. Dactylo-
podite slender and curved.

Second gnathopod of 9 (fig. 3, e) similar to the first gnathopods of
J1 and 9, but meropodite with the prominence of the under margin more
pronounced (but not triangular and pointed, as in the second gnathopod
of the oT) ; process of lower margin of carpopodite a little longer than
that of the first gnathopod, and palm still more elongated, distinctly
longer than the carpopodite, and less triangular than that of the first
gnathopod of the 9- (This is very dissimilar to that of H. dentata
inermis. .)

Peraeopods : First (fig. $,/}, second and third of about the same length,
fourth longer than third, fifth (fig. 3, g] about as long as fourth. The
last (fifth) extends backward a little beyond the tip of the first uropod.
Basipodite of third to fifth enlarged, oval, that of fifth pair larger than
those of the third and fourth. Hind edge of third, fourth and fifth ser-
rated, most distinctly so in the fifth. Accessory branchiae on the first to
the fifth peraeopods. No ordinary branchiae on fifth.

Uropods (fig. 3, h] : First and second with spines on both rami. Third
uropods : ramus about as long as the peduncle, only slightly extending
beyond telson.

Telson (fig. 3, h}, almost semicircular, or, more correctly, half-elliptic,
with a pair of fine setae on the rounded hind margin.

Color (in alcohol) whitish or grayish.
Length of large <$ : 14-16 mm.

Remarks. — The following species of Hyalella have been described,
which approach more or less closely the present one :

1. H. dentata Smith (1874, Geol. Surv., p. 608, pi. i, f. 3-6, and Rep.
Fish Comm., p. 645, pi. 2, f. 8-10), United States.1

2. H. inermis Smith (1874, Geol. Surv., p. 609, pi. i, f. i, 2). Colo-
rado, Utah, Florida.

This form is given by Faxon (1876, p. 373, textfig. 35) as Allorchestes
dentatus var. inermis from the region of Lake Titicaca, from San Antonio,
Peru (saline water, 3,300 feet above the sea), and from Puerto Bueno,
Smyth Channel, Strait of Magellan (probably fresh water).

Faxon further describes (1876, pp. 374, 375, textfigs. 36, 37):

3. Allorchestes dentattis\'ax. gmcilicornis Fax., from near Campos (Rio
de Janeiro), Brazil.

4. Allorchestes longistilus Fax., from the same locality.
Wrzesniowski (1879, pp. 176, 177, 199) describes:

5. Hyale jelskii Wrz., from Peru, east side of Cordilleras, 8,000 feet
(Pumamarca).

6. Hyale lubomirskii Wrz., from Peru, west side of Cordilleras, 8,000
feet (Pacasmayo).

7. Hyale dybowskii Wrz., from Peru, west side of Cordilleras, 7,000
feet (Paucal, Montana de Nancho).

Finally, Stebbing (1899, pp. 406, 407, pi. 32, A, E] describes:

8. Hyalella warmingi Stebb., from Lagoa Santa (Prov. Minas Geraes,
Brazil).

9. Hyalella meinerti Stebb., from " Laguna di Espino."2

All these forms belong to the genus Hyalella, founded by S. J. Smith
(1874), and more sharply defined by Stebbing (1899, pp. 397-398) in his
key to the genera of the family Orchestiidce.

H. dentata from the United States differs from our species (and all the

*As has been surmised by Smith and Faxon, this species is very likely identical with Allorchestes
knickerbockeri Bate (1862, p. 36, pi. 6, f. i) from New York, and possibly with Amphithoe aztecus
Saussure (1858) from Vera Cruz, Mexico. If the latter should prove to be true, the specific
name of aztecus should be used.

* I have tried to locate "Laguna di Espino," but have been unable to do so. Places called by
the name of "Espino" are found in Honduras and Venezuela (prov. Guarico), but no "Laguna di
Espino" is known to me.

654 PATAGONIAN EXPEDITIONS : ZOOLOGY.

rest) in the spiniform prolongation of the segments of the pleon. This
character, however, seems to be of minor importance, since there are
intergradations in this respect between the typical H. dentata and H.
inermis in the United States (see Smith, 1874, Fish Comm., p. 647 ;
specimens from Florida). Faxon regards H. inermis only as a variety
of H. dentata.

In all other characters, H. dentata as well as H. inermis are closely
allied to our species, especially the following characters agree :

1. General shape of body and eyes.

2. Length of antennulae and antennae. In H. dentata and H. inermis
these are considerably shorter than half of the body.

3. Shape of the second gnathopod of the J*. Especially the propodite
is directly identical, as will be seen by comparing our figure (3^) with the
figure of this joint of//, dentata (cT ad.) given by Smith (1874, Geol. Surv.,

pl. i, f- 3).

4. Relative length of the peraeopoda.

5. Shape of uropods and telson.

The chief differences are the following :

1. The number of joints of both antennulae and antennae is greater in
our species. Although these parts are about as long as those of H. den-
tata and inermis, the number of joints is slightly greater in H.patagonica
(in dentata and inermis, 7-9 in the antennulae, 8-12 in the antennas; in
H.patagonica^ 8-12 in the antennulae, 9-17 in the antennas). The joints
of the peduncles are a little different in length ; while of those of the an-
tennulae, in H. dentata and inermis, the two distal ones are about alike,
the last joint, in our species, is a little shorter than the second. In the
antennae, the second and third joints are alike in H. dentata and inermis,
while, in H. fiatagonica, the third is distinctly longer than the second.
These differences, however, seem to be of minor importance.

2. In the first gnathopod of the $ as well as the $, the propodite is, in
H. patagonica, distinctly broader and more triangular ; the propodite has a
distinct lobiform prominence, which is much more developed than in H.
dentata and inermis, and, consequently, the carpopodite appears shorter
and broader in our species.

3. The same is true of the second gnathopod of the 9 ' the carpopodite
and propodite are shorter and comparatively broader in our species, and
the process of the carpopodite is more pronounced. The propodite in H.
dentata and inermis is much longer than in our species.

ORTMANN: CRUSTACEA OF SOUTHERN PATAGONIA. 655

4. In our species, the meropodite of the second gnathopod of the '$
has a triangular, pointed prominence on the lower margin, while in H.
dentata and inermis this process is blunt and obtuse.

5. Size of our species much larger, up to 16 mm., while H. dentata and
inermis measure not more than 6 mm.

Thus we see that H. patagonica differs from H. dentata, and especially
from H. inermis, in some slight and unimportant features of the antennulae
and antennae, and in some very marked characters of the first and second
gnathopods of the $ and 9, and in size. Nevertheless, these three forms
seem to be very closely allied in the general shape of the body, length of
antennulae and antennae, and the general shape of the chelae of the second
gnathopods of the J1.

It remains doubtful, whether Faxon's H. dentata var. inermis from
South America is really identical with the form of the United States.
Faxon says that his Lake Titicaca specimens exhibit some differences in
the shape of the propodite of the second gnathopods of the cT, but his
figure does not reveal them in a sufficient degree. Considering the fact
that we possess several hundred individuals of our species, and that they
all show a great uniformity in their characters, and that the differences
mentioned above are constant among them, it is possible that also the
Titicaca form — of which Faxon had only 6 specimens — might be a good
species. As to the specimens from Peru and the Straits of Magellan,
Faxon does not give any details of their characters, but I suspect very
strongly that those from the latter locality really belong to our species.

H. dentata var. gracilirostris (Fax.) from Brazil differs at once from all
others, discussed so far, in the much longer antennae, which are half as
long as the body. There may be other characters that differ, to which
Faxon does not refer. He had only one female.

H. longistilus (Fax.) from Brazil differs at once in the third uropods,
which are much longer, and in the longer antennulae and antennae. Car-
popodite of second gnathopod of J1 more oval, and less distinctly triangular.

H. jelskii (Wrz.) from Peru differs:1

i. Antennulae and antennae much longer, and the antennae of the <$

lWrzesniowsky does not give any figures of his species, and consequently we cannot form,
in some points, a good idea as to their characters. Nevertheless his descriptions are generally
clear, and do mention characters that show conclusively that his species are different from H.
patagonica.

656 PATAGONIAN EXPEDITIONS: ZOOLOGY.

are two thirds of the length of the body. Number of joints about the
same as in our species (antennae of <?, 18 joints).

2. Shape of first gnathopod different, the carpopodite large, distinctly
longer (i# times as long as propodite).

3. In the second gnathopods of the <?, carpopodite about one third of
the propodite (expression ambiguous: " dreimal kuerzer"), and propo-
dite apparently shorter than in our species. For the rest, the propodite
seems to possess a similar shape, although the spinules of the palmar
margin seem to be different.

4. The propodite of the second gnathopod of the 9 seems to be quite
different, being 2.yz times as long as broad.

5. No accessory branchiae on the fifth peraeopods.

6. Size smaller (5 mm.).

Thus it seems that this species is much more different from H. pata-
gonica than H. inermis, especially in the shape of the antennulae, antennae
and gnathopods.

H. hibomirskii (Wrz.) from Peru differs from our species :

1. Head shorter, and eyes oval (not round).

2. Antennulae and antennae longer (antennae of $ over one half of the
body). Number of joints slightly greater.

3. Second gnathopods of <$ apparently similar to our species, but palmar
margin cut into two lobes, and meropodite \yz times as long as carpo-
podite. In the 9, the propodite is longer than in our species, almost
twice as long as wide.

4. Size smaller (6 mm.).

Here the first gnathopods are apparently more like //. patagonica (car-
popodite hardly longer than propodite). This species resembles more
H. inermis in the first and second gnathopods, but head, eyes, antennulae
and antennae are different.

H. dyboivskii (Wrz.) from Peru differs from our species :

1. Eyes oval, dilated below.

2. Antennae longer (half as long as body). Number of joints of
antennulae and antennae near that of our species (antnl. 10-13, ant-

H-I5).

3. Carpopodite and meropodite of second gnathopod about one third

as long as propodite.1 For the rest the first and second gnathopods seem

l"Zweimal kuerzer." This expression is very ambiguous, in a double sense.

ORTMANN: CRUSTACEA OF SOUTHERN PATAGONIA. 657

to resemble those of H. patagonica, although the description is very short
and incomplete.

This species seems to be the most closely allied form among thoSe
described by Wrzesniowsky ; it differs, however, distinctly in the shape
of the eyes and the length of antennulae and antennae.

H. warmingi Stebb., from Lagoa Santa, Brazil.

This species differs at once and strikingly in the shape of the propodite
of the second gnathopod of the d\ which is more oval, and in the shape
of the first gnathopod and the second gnathopod of the 9. Also the
antennae are much longer, so that we do not need to compare it further.

H. meinerti Stebb., from " Laguna di Espino."

This is entirely different in the third uropods, which resemble those of
H. longistihts (Fax.), and further, the shape of the first and second
gnathopods and the length of the antennae are quite unlike our species.

Thus we see that the species most closely allied to H. patagonica is H.
inermis of the United States. According to Faxon, this species (or variety)
is also found in Peru, near Lake Titicaca, and in the region of the Straits
of Magellan. Yet Faxon regards differences in the shape of the first and
second gnathopods not as specific characters, and thus it is quite possible
that his South American specimens represent good species, different from
H. inermis. I have said above that the differences of H. patagonica from
H. inermis, although seemingly unimportant, are constant among the
large number of our specimens, and consequently, I am forced to regard
this Patagonian form as a new and good species.

The fact that the type of fresh-water amphipods, represented in the
United States by Hyalella dentata and inermis extends, apparently,
throughout America, over Central and South America to the Straits of
Magellan, while this genus is found nowhere else, is very interesting from
a zoogeographical point of view.

On the eastern Patagonian coast this species has been found as far north
as Bahia Blanca (Prov. of Buenos Aires), 38° 42' S. (Berg, 1900), while
on the western coast it does not seem to go beyond Trinidad Channel
(50° S.).

Remarks. — According to Stebbing, the specific name of P. granulosa
has to supersede that of P. verrucosa, having been published (on Jacqui-
not's plate) not later than in 1847, while L. verntcosa of Dana was pub-
lished in 1852.

The two young individuals from Cape Fairweather correspond closely
to L. verrucosa of Dana (1852, p. 428, pi. 26, f. 16). Both have the
length of the carapace, 27 mm. The specimens from Punta Arenas are
all larger, and most of them seem to be adult ; the smallest, a soft shell
female, is 61 mm. long (carapace only), and this one is intermediate in
sculpture between the young and adult specimens ; the tubercles of the
surface are more crowded than in the latter, but a little more distant from
each other than in the former. The same is true of the granulations of
these tubercles, they being less developed than in P. verrucosa, but more
strongly than in the adult individuals. Length of adult males : 92, 101,
107 mm.; of an adult female: 72 mm.

This leaves no doubt as to the identity of P. granulosa and verrucosa,
the former being only the young stage of the latter, as already Bouvier
(1896) maintained.

Remarks. — The specific differences of this species have been set forth
best by A. Milne-Edwards, and I have been able to verify them in our
material.

Henderson's M. subrugosa is the true M. subrugosa, although he also
gives, among the synonyms, Grimotliea gregaria (with a ?) : he states
expressly (p. 125) that no specimens representing the latter form were
taken by the Challenger, and, further, he doubts the correctness of the
identification of these two species.

It is doubtful whether this species is also found in New Zealand, since
it has been confounded by some authors with M. subrugosa. A form

New Zealand : he distinguishes it well from M. stibrugosa, but says that

as Milne-Edwards' adult male). It agrees well with the description in
every respect, but the spinules of the upper part of the carapace are less
distinct, although present. The latter character seems to be not very
important, since a variety of M. stibrugosa (var. australiensis] also pos-
sesses a larger number of spinules on the carapace than the typical
subrugosa.

Remarks. — The young J1 from San Julian, and the three young $ from
Punta Arenas, of the lengths: 2.5-3-3.5-4 mm., agree completely with
Dana's H. pitbescens, which is said to be one tenth of an inch long ( = 2-3
mm.) : the form of the carapace is more rounded (less transverse than in H.
planatus], the walking legs (and sometimes the carapace) are slightly pubes-
cent, and the sides of the male abdomen are parallel, with the exception of
the last joint. A young J1 , 6 mm. long has the typical form of the male
abdomen of H. planatus, but the form of the carapace is less transverse.
The pubescence is not present. Larger males (from 10 mm. upward)
acquire by degrees the greatly swollen chelipeds. Our largest male has

We see at once that, while the prevailing features of the southern
Patagonian marine fauna are made up chiefly by peculiar species, another
large part of the fauna shows unmistakable affinities to other Antarctic
countries. Looking more closely upon the peculiar types (group 4), we
are able to state the following particulars with regard to their relationship
to other parts of the world.

The genera Elminius, Edotia, and Eurypodius do not find any closer
relations elsewhere. Exosphceroma and Serolis are distinctly Antarctic
types, while the affinities of Rocinela and Munida are more or less cosmopoli-
tan. There remain only the two Lithodidce and Hypopeltarium. The Litho-
didce apparently are to be classed with those forms which possess a kind
of bipolar distribution, but where the two polar areas are connected along
the western coast of America. This has been called by the present
writer " meridional distribution," * and such cases are not considered to
belong to " bipolarity " in the original sense. Hypopeltarium, which is
represented in European waters by Atelecyclus, might be taken for a case of
bipolarity, if it were not for the fact that a species of this genus lately has
been discovered in the West Indian region.2 This renders it impossible
to regard this case (of Hypopeltaritvn and Atelecyclus] as one of bipolarity.

Examining the Antarctic types (group 3), we find that none of them
can be regarded as a representative of any characteristic Arctic form,
although among the five isopods the generic affinities need further investi-
gation. This much is known, that all five of them are hardly represented
in any part outside of the Antarctic regions. The same is true of Halicar-
cinus, while Munida, as has been stated above, is cosmopolitan.

Thus, among the forms discussed here, the bulk is to be regarded as
peculiar to this region, representing a local Magellanian fauna. A large
part of this fauna exhibits characteristic Antarctic affinities, pointing to a
former closer connection of the different parts (South America, New Zea-
land, Australia, Kerguelen, etc.). The remaining small number represent
either immigrants from the north, along the western coast of America, or
more or less cosmopolitan types.

The Magellanian fauna, according to this material — and this is no
doubt a fair representation of the more abundant forms of it — is descended

from a general Antarctic fauna, which has developed some peculiar local
types ; a few elements of it (Elminius, Edotia, Eurypodius] seem to be
altogether peculiar to these parts, while a few others belong to different
sources ; some immigrated from the north, and others are cosmopolitan
forms, the original home of which cannot be traced. No indications of
bipolarity are found, that is to say, in no case are the affinities of any of
these Antarctic forms to Arctic forms closer than to any other region of
the earth.

This points distinctly to the former existence of an Antarctic fauna
peculiar to the shores of the supposed old Antarctic continent, of which
fauna the Magellanian is a slightly modified offshoot, blended with a few
types of different, presumably northern, origin and the view is supported
that the Antarctic fauna, in its origin, is totally different from the Arctic.1

With regard to the fresh-water fauna we may make the following
remarks.

Most of the species recorded here belong to the class of those small
fresh-water organisms, for which exceptional means of dispersal (passive
transport by wind, water-fowl, etc.) are admissible, and even observed, so
that a more or less cosmopolitan distribution is not astonishing. Although
most of the species (except Daphnia hastata] are peculiar to Patagonia,
the genera are universally distributed.

A very remarkable exception to this is presented by the Copepod genus
Pseudobceckella. The distribution of this and the allied genera \Bceckella,
Bczckellopsis, Par abac kelld] is almost exclusively restricted to the Antarc-
tic countries (only in S. America the range extends into Brazil). I give
here a synopsis of the known localities, following Mrazek's (1901) classi-
fication.

The genus Boeckella (typ.) Mraz. contains three species from Australia
and New Zealand (B. triarticulata (Thorns), minnta Sars, robusta Sars).
To these we have possibly to add : B. gracilipes Dad., gracilis (Dad.) and
Pygnuza Dad., from Patagonia and Chili.2

Pseudobosckella Mraz. contains the following species : brasiliensis (Lubb.),
Patagonia and Brazil ; poppei Mraz., S. Georgia and S. Patagonia; longi-
cauda (Dad.) and entzi (Dad.) both from Patagonia ; and probably also :
dubia (Dad.) and silvestrii (Dad.) from Patagonia.

2Daday in Term. Fuz., v. 25, 1902, p. 444.

ORTMANN: CRUSTACEA OF SOUTHERN PATAGONIA. 665

Bceckellopsis Mraz. possesses only the species B. bergi (Rich.) from
Buenos Aires and S. Patagonia.

Parabceckella Mraz. is made up of P. brevicaudata (Brad.) from Kergue-
len and Punta Arenas.

This distribution is so remarkable, including only S. America, S. Georgia,
Kerguelen, Australia and New Zealand, that this group of genera, which
are no doubt closely related to one another, clearly is to be classed with
those freshwater and land animals that point to a former connection of
these regions.1 Under the same head comes also Lepidurus hatcheri Ortm.,
of which we have demonstrated above, that it is most closely allied to
L. angasi Baird of South Australia.

HIRUDINEA OF SOUTHERN PATAGONIA.

BY

J. PERCY MOORE,

UNIVERSITY OF PENNSYLVANIA.

N'OTHING whatever was known of the fresh-water leech fauna of
the extreme southern end of South America — of the entire region
south of Valdivia on the Pacific coast and of Montevideo on the
Atlantic side — until the publication in 1890 of Blanchard's account of
the leeches collected by Dr. Michaelsen on the Hamburg Expedition to
the Straits of Magellan. In this paper the following species were de-
scribed from Tierra del Fuego and Punta Arenas on the Straits of Magel-
lan, all having been collected at no great distance from the coast in ponds,
lakes and swamps : Semiscolex variabilis Blanchard, Glossiphonia (Helob-
delld] chilensis Blanchard, Glossiphonia (Helobdelld] michaelseni Blan-
chard, and Glossiphonia {Helobdella) scutifera Blanchard.

The material described in the present paper was collected inland along
the base of the mountains at elevations as high as 2,500 ft, and particularly
from the numerous springs and streams which feed the Rio Chico — a
region from which no leeches have hitherto been described. As regards
the number of species the collection is small, comprising but six, belong-
ing to only two families. But several of these are represented by a great
many examples. Three of the four species recorded by Blanchard from
southern Patagonia are represented ; and two new species are included,
both of which possess functional nuchal glands, which in Glossiphonia
duplicata are greatly developed. So far as appears in the present very
incomplete state of our knowledge of the fresh-water leeches of this region,
the most striking feature of the fauna is the predominance of small glos-
siphonids of the group designated by Blanchard Helobdella. Including
G. stagnalis, which has been found as far south as Valdivia, this fauna
includes most of the known species with functional nuchal glands.

SEMISCOLEX.
SEMISCOLEX VARIABILIS R. Blanchard.

(Plates XLIX, Figs. 1-9; L, Fig. 12.)

Except for the narrower prostomium and smaller mouth, the general
aspect is similar to Hczmopis, a resemblance which is especially striking
in the case of a quite small individual. The larger specimens are some-
what flattened posteriorly and rather sharply constricted at the region of
the sexual pores, anterior to which the body is narrower and nearly terete.
The arrangement of the eyes is shown in figures i and 7. The relative
position of the pigment cups and the direction of the axes of the eyes
are sufficiently obvious. The pigment cups of the first three pairs are
larger and more conspicuous than the others. No sensillae are discernible.

Sixteen pairs of quite conspicuous nephridial ducts, appearing as short
tubes which pass obliquely backward through the integuments, open close
to the posterior margin of annulus b2 of every somite from IX to XXIV.
The anus is a conspicuous opening with lobed margins as in Hcemopis.

Like Blanchard's types all three of the specimens studied by me have
the male genital orifice situated in the middle of XII bi. In the mature
examples it is a rather prominent four-rayed opening, slightly elevated on
a broad, low papilla, to support which the annulus is lengthened mesially.
In all three of Blanchard's specimens the position of the female pore dif-
fered, ranging from XII a2\b$ to XII b6, being separated from the male
pore, therefore, by two and one half, three and one half and four annuli
respectively. The intermediate condition was exhibited by an example
from Punta Arenas, Patagonia, and to this the three here described are
exactly similar. The female pore in all is a minute opening in a
depressed area situated at XII bjlbd.

Annulation. — The details of annulation of the best preserved mature
example are exhibited in Plate XLIX, figs. 2, 3, 5-8, and of the young
example in figure 4.

Somites I, II, III and IV are separated by no distinct furrows, though
slight wrinkles may be caused to appear on the median part of the head
between the eyes by bending this region upward. These furrows, together
with the position of the closely crowded anterior three pairs of eyes, show
that the first three somites are uniannulate. Somite IV is apparently so
also, or else aj is very obscurely distinct, for, although the distance

MOORE: HIRUDINEA OF SOUTHERN PATAGONIA. 671

between the third and fourth pairs of eyes is somewhat greater than that
separating any of the preceding pairs, no distinct intervening annulus
can be detected.

V is biannulate; the two annuli — (ai + a2) and aj — are of about
equal length. The pigment cups of the fourth pair of eyes are at about
the middle of the anterior annulus and placed on the antero-internal face
of the sensory cells. The furrow (ai-\-a2)/aj is incomplete in the small
specimen and the pigment cups of the eyes reach into IV, an appearance
due in part to contraction and in part to the position of the head when
drawn.

VI is also biannulate. On the dorsal surface a faint furrow (aila2] is
present, extending about as far as the eyes in the larger example, but
detectable under the compound microscope for the entire width of the
head of the smaller one. The pigment cups of the fifth pair of eyes,
which cover the anterior face of the sensory cells, lie directly beneath this
incipient furrow. The second annulus (aj) is quite distinct all around,
making the somite biannulate ventrally as well as dorsally.

VII is triannulate ; aj is distinctly longer than ai or a2 which are
obviously more closely associated, the furrow ail 0,2 being less distinct
than a2/aj, especially on the ventral surface.

VIII is quadriannulate. Of the four annuli ai is just appreciably longer
than a2 and shows a faint dorsal furrow, bilb2 ; b$ and bd are distinctly
shorter than ai and a2, and the furrow b$lb6 is a trifle less deep than
the others.

There are sixteen distinctly quinqueannulate somites, IX to XXIV in-
clusive. In IX the relative lengths of the annuli are represented by the
formula bi = b2 < b$ = b6 < a2 ; IX bi and b2 = VIII b$ and 56. By
about XI the formula becomes bi=b2 — b^ — b6<a2, which it remains until
about XXII where the somites begin to decrease in relative and abso-
lute length, owing to diminution of the posterior annuli. Here
a2 > bi = b2 > b$ — b6.

XXV is quadriannulate, bi and b2 being smaller than a2, which is
again slightly smaller than aj. Across the latter, traces of the furrow
b$lbd may be detected. Following XXV are two small rings between
which the anus is placed. Although there are no visible sensillae to
authenticate the determination, these are interpreted as XXVI and XXVII
respectively.

672 PATAGONIAN EXPEDITIONS I ZOOLOGY.

The small specimen shows immaturity not alone in the condition of the
reproductive organs, but in the external annulation. Throughout the
middle region of the body the secondary annuli into which ar and aj
are divided are imperfectly separated. This is expressed not so much in
their relative size, which is scarcely appreciably less than in the mature
specimen, but very obviously in the relative shallowness of the furrows
bilb2 and b$lb6 as compared with bzla2 or a2lb$. Figure 4 is a careful
camera drawing of the ventral surface of this specimen when mounted in
glycerine, in which medium the ganglia can be seen quite clearly and are
also represented in the figure. Generally the ganglia lie principally
within a2 throughout the quinqueannulate region. The subcesophageal
complex is in VI and VII and the supracesophageal chiefly in VI. On
the dorsal surface the furrow a2\b$ is distinctly deeper than &2la2, result-
ing in the natural division of the five annuli into two groups of three and
two respectively.

Alimentary Canal. — The upper lip (prostomium) is somewhat wrinkled
below, but lacks any definite and distinct median sulcus. The mouth is
small in the preserved specimens, scarcely larger than in a nephelid in
the larger, but relatively larger in the smaller one. Jaws are absent,
though the median dorsal one is probably represented by a small rounded
tubercle occupying the corresponding position and surrounded by a shallow
trench, immediately laterad to which is a pair of broad, low, longitudinal
muscle columns, and again beyond these a similar pair of narrower ones,
but no trace of lateral jaws. Muscles and gland ducts enter the dorsal
tubercle, but there are no teeth. A low, narrow fold passes between the
buccal chamber and pharynx dorsally, but fades out ventrally.

The pharynx (Plate XLIX, fig. 9) is capacious and extends to the
region of the genital pores in the middle of XII. Its inner surface is
thrown into slightly marked longitudinal muscular ridges. These begin
anteriorly as a dorsal pair and a median ventral one, alternating with
three much narrower ones. Each of the larger set almost immediately
divides into several, so that for the greater length of the pharynx ten or
twelve ridges are recognizable. None of these is strongly marked and the
internal surface of the pharynx is nearly smooth and regular, but shows
a slight tendency toward a triangular section.

A stomach of very simple character extends from XIII into XIX, where
it passes, without any very sharp demarkation, into the intestine. Seven

MOORE: HIRUDINEA OF SOUTHERN PATAGONIA. 673

valves, which correspond in position to the preganglionic muscular sheets,
divide it into as many slight sacculations, the posterior ends of the last
of which are produced into a pair of quite rudimentary caeca, of such
small size and so closely embracing the intestine that they were entirely
overlooked upon the first examination. They scarcely extend beyond
the limits of the neural annulus of XIX.

The intestine is somewhat distended with food, to which, in contrast to the
emptiness of the s'tomach, the somewhat greater diameter of the former is
probably due. Its walls are excessively thin and delicate and somewhat
regularly, but slightly, sacculated for the anterior half. It reaches to XXIV,
beyond which a short rectum extends to the anus. That this species is
not a habitual blood-sucker, but, like our common Hcemopis marmora^is,
subsists chiefly on small invertebrate animals and the organic contents of
mud, is shown by the contents of the intestine and stomach, which consist
of remains of tubificid worms, rhabdocoele planarians and diatoms.

Reproductive Organs. — The reproductive organs (Plate L, fig. 12),
while approaching in character most closely those of Hcemopis, yet exhibit,
if the single example dissected be entirely normal, a number of striking
peculiarities. The pairs of testes occupy the interganglionic intervals
from XIV/XV to XXII/XXIII ventrad of the alimentary canal. The
first pair presents the ordinary appearance, but the remaining eight are all
double, two closely appressed but perfectly distinct spheroidal testes with
separate efferent ducts occupying each interval. The actual number of
testes is, therefore, at least seventeen pairs and, as the vasa deferentia
extend some distance posterior to the last, it is probable that additional
material would permit of the demonstration of at least one more pair ; and
a pair may also occur at XIII/XIV. Both the vasa efferentia and vasa
deferentia are excessively slender, but the latter in particular are rendered
very conspicuous by a thick covering of pear-shaped groups of gland cells,
which are far more thickly clustered dorsally than ventrally. Anterior to
the testicular region the glands diminish in number and disappear alto-
gether in somite XII. At the same time the walls of the sperm duct
acquire greater firmness and it may be traced as a tortuous tube as far
forward as the position of the male pore, where it bends mesially in a
recurrent limb.

In somites XIV and XV each vas deferens becomes converted into a
closely coiled, twisted and massed tube with thick walls and of irregular

674 PATAGONIAN EXPEDITIONS: ZOOLOGY.

diameter, the epididymis. This passes, without any enlargement into a
special sperm sac, into a short thick ductus ejaculatorius which, without any
apparent change in its diameter, is lost at once in the substance of the
prostate region of the atrium, into which it enters. The atrium is straight
— not bent on itself — and is chiefly remarkable for the great size of its
prostate region, which projects freely caudad beyond the point of entrance
of the ducts fora distance equal to more than one-fourth of the entire length
of the atrium, and reaches beyond ganglion XIX. This entire region is
covered with a layer of prostate glands. Anterior to the ducts the atrium
becomes a thick-walled muscular tube (the penis sheath) which is much
narrower than the prostate region and tapers somewhat to the external
end. It is unfortunate that no material was available for sectioning to
throw light upon the structure especially of the prostate end of the atrium.

The female organs (Plate L, fig. 12) consist of a single ovary (that of
the left side being probably abnormally absent) lying in the posterior part
of somite XII. The right oviduct (the left being absent) enters a well-
marked glandula albuginea, within which it is somewhat coiled. It emerges
as the common oviduct, which is not very clearly differentiated from the
glandula, and enters the posterior end of the vagina, which is somewhat
enlarged but lacks a distinctly separated ovisac at this point. The entire
female organ is sharply bent on itself at the point where the- oviduct passes
into the vagina or uterus. The nerve cord passes to the left of the terminal
end of both atrium and vagina.

In following Blanchard in placing this species in Semiscolex, I have
simply accepted his determination, as I have never had the opportunity of
dissecting any other species of that genus, and Kinberg's description is
itself insufficient. Verrill's Semiscolex grandis and Forbes' Semiscolex
terrestris are very different and both are true species of Htzmofiis, though
the absence of teeth in the former may be considered by some as a suffi-
cient basis for generic separation. Semiscolex variabilis also evidently
stands with Hcemopis in the distichodont division of the Hirudinidae, for,
although the alimentary canal differs from that of Hamopis and resembles
such a nephelid as Trocheta in the rudimentary jaws, valvular stomach and
all but absent caeca, it has the proportions of and can readily be derived
from that of Hczmopis. The reproductive organs resemble the latter genus
in the length of the vagina and penis sheath, the enlarged prostate, etc.,
though in the absence of any special sperm and ovarian sacs on the ducts
it rather approaches Hirudo and its allies.

MOORE: HIRUDINEA OF SOUTHERN PATAGONIA. 675

Semiscolex variabilis appears to be a small leech. Blanchard's speci-
mens varied from 10 to 37 mm. in length. The smallest example here
described measures 8 mm., the largest, which is poorly preserved, about
23 mm., and the individual which furnished most of these notes and is
represented of natural size in fig. i has the following measurements.

Length, 2 1 mm.

Anterior end to male pore, 6.5 mm.

Width at male pore, 2. i mm.

Greatest width (XX), 3.6 mm.

Diameter of posterior sucker, 1.3 mm.

Depth at male pore (about), .8 mm.

Greatest depth (about), 1.4 mm.

Two specimens come from a "large spring 30 miles above Sierra Oveja,
Rio Chico, Feb., 1899," Station 22 ; the third is from a " drying-up pool
near Arroyo Eke, Alt. 2100 ft., Feb., 1899," Station 43.

GLOSSIPHONIA DUPLICATA sp. nov.

(Plates XLIX, Fig. 10; L, Figs. 16-22.)

This species resembles G. (Helobdella) scutifera R. Blanchard, but is
readily distinguished by the distinctly double annuli, the form of the
nuchal plate, the metameric color pattern, etc.

Without exception all of the very large number of preserved specimens
are stout and thick, less wide and flattened, but much deeper and more
strongly convex dorsally than examples of G. scutifera preserved in the
same bottles. The anterior end is somewhat slender, the posterior
broadly rounded, the greatest width being at about the beginning of the
posterior third. The anterior sucker is small, with a contracted opening
and thick margin ; the prostomium prominent. In almost all of the
specimens a low elevation arises from the middle of the sucker, with a
deep groove bounding it anteriorly. The mouth is rather large, situated
in a thickening which represents the ventral portion of somite III, and is
the center of several radiating furrows (Plate L, fig. 18).

The contracted, thick-rimmed posterior sucker is so strongly directed
ventrad that it is entirely concealed from above (Plate L, figs. 19 and 20).

Following are the measurements of the type specimen, than which
some examples are several millimeters longer, as well as relatively deeper.

Depth at anus, 1.2 mm.

Annulation. — Somites I and II are found in the preocular lobe, across
which a very faint furrow can usually be detected and is always quite
evident in the larger specimens. Ill is biannulate, the first annulus
larger. IV is also biannulate, the anterior annulus bearing the single
pair of eyes, which are generally lightly pigmented and consequently in-
conspicuous. This somite is usually a trifle longer than III, but in some
examples they are equal. The example figured is slightly abnormal, the
left half of the furrow IV/V being displaced on the dorsal side. V is
likewise biannulate, but is considerably longer dorsally, where the enlarged
anterior annulus is quite distinctly subdivided by a furrow, which separates
a smaller ai from a larger a2. This furrow ends at the margins of the
lips so that ventrally there is no trace of this subannulation (Plate L,
figs. 17, 18 and 22).

Although VI must be reckoned as a triannulate somite both above and
below, it does not show the typical condition, inasmuch as ai and a2 are
rather closely united on the ventral side, and aj is the only annulus
which exhibits any trace of that development of secondary annuli which
is so characteristic of this species among its close allies, and even this
trace is usually wanting.

Somite VII is the first typical one. The three annuli are of about
equal size and each is usually distinctly subdivided into two nearly equal
secondary rings by a cross-furrow, which is especially well-marked on ai
and aj, and much less distinct or even absent ventrally. These cross-
furrows correspond in position with superficial annular lacunae which
encircle each primary ring of the complete somites, and they have a con-

MOORE: HIRUDINEA OF SOUTHERN PATAGONIA. 677

stant relation to the bands of circular muscles. Each primary annulus
possesses five of these bands, between the second and third of which the
furrow passes on ai and between the third and fourth on 0.2 and <zj.
VII aj is somewhat swollen at the mid-dorsal line, where also the furrow
VII/VIII may become obliterated for a short distance owing to the
development of the nuchal gland on the succeeding somite. The nuchal
plate may sometimes slightly overlap VII aj, or the latter may be some-
what constricted mesially by the glandular swelling. In some examples
the cross-furrows are not visible on VII and they are always less distinct
than on the larger annuli of VIII and succeeding somites.

VIII is chiefly remarkable from the presence of the nuchal gland. This
is confined to az, which, as a consequence, is swollen and more or less
elongated in the median dorsal region. The horny plate secreted by the
gland, which it covers like a scale, is remarkably thick and conspicuous.
In color it has a very dark brown center and a paler border. Unlike G.
stagnalis it is broader than long, anteriorly very convex, posteriorly slightly
convex or straight. It slightly overlaps or just reaches VIII #<? and just
reaches the furrow VII/VIII anteriorly. But little change is noticeable
in the character of the somites to XXIII inclusive, though the secondary
furrows are frequently more distinct on the somites immediately succeed-
ing the region of the genital pores.

On XXIV, which remains triannulate, the secondary furrow is present
on ai only and even there has become less distinct. On the ventral side
the annuli of this somite are crowded together by the posterior sucker.
XXV is biannulate and of much reduced length. The first annulus is
about one half larger than the second and about equal to the contiguous
annulus of XXIV. XXVI is faintly biannulate, aj being very narrow
and indistinct. XXVII is uniannulate and is cut into two halves by the
anus, which thus lies just posterior to XXVI (Plate L, figs. 19, 20
and 21).

Pigmentation. — From many of the specimens the pigment had faded
altogether, but all of those in which this is not the case show a very evi-
dent metameric arrangement, resulting in many cases in a strongly annu-
lar pattern, which is dependent on the disposition of the muscles. In a
typical example (Plate L, fig. 17) the ground color is a faintly mottled, very
pale brown, which deepens on the margins and fades to a gray on the ven-
tral surface. Dorsally, two broad, ill-defined, longitudinal bands extend

678 PATAGONIAN EXPEDITIONS: ZOOLOGY.

nearly the entire length. They are indistinct anterior to the nuchal gland
but are usually conspicuous from that point to the anus. The median
interspace between the bands corresponds to nine longitudinal muscle
bundles, the bands themselves to five each (they are formed of six lines
of pigment cells corresponding to six intermuscular lines), and the dis-
tance separating them from each margin to eleven.

Annulus ai of each somite from VI to XXVI inclusive is much more
heavily pigmented than the others, and the pigment is especially aggre-
gated on its posterior half, the b2 constituent. Thus in such typical cases,
the dorsum is marked by well-defined, narrow, metameric, transverse bands,
which become fainter anteriorly, where they can seldom be traced beyond
VI, and altogether diffuse posteriorly on XXV and XXVI. These trans-
verse bands extend the entire width of the dorsum, both mesiad and
laterad of the longitudinal stripes. Other examples are less typical and
show the pigment spreading over aj as well as bi, but the former never
becomes so dark and is brown rather than blackish ; a2 always remains
paler. The characteristic pattern is due to black pigment cells deep-
seated between the muscle bands.

Reproductive Organs. — The male pore is situated at ~X.\\aila2y the
female at XII a2la^. The former is the more conspicuous, and in some
specimens, but not in the type, is in the center of an elliptical disc, which
is wedged between the two contiguous annuli. There are six pairs of
testes (Plate XLIX, fig. 10) of globoid form alternating with the gastric
caeca and filling up the spaces between these. Dorso-ventrally they are
deeper than the caeca, reaching the same dorsal level, but extending to a
lower ventral one. Though inter-metameric in position, they probably
belong to the somites in which their posterior halves lie, consequently to
XIV to XIX inclusive. The vasa efferentia and vasa deferentia are
excessively delicate and can be traced only with difficulty. The vas
deferens of each side passes dorsad of the caeca and mesiad of the testes.
Reaching the posterior end of XII, it bends sharply mesiad, traversing
muscles and pharyngeal glands ventrad to the ducts of the latter, and
reaches the ventral sinus, through which it extends caudad, increasing,
first abruptly and then gradually in diameter. The change from the
minute vas deferens to the larger epididymis takes place in XIII. The
long epididymal loop (sperm sac) thus formed is very conspicuous,
reaching to the posterior end of XIX, and, being considerably convoluted

MOORE: HIRUDINEA OF SOUTHERN PATAGONIA. 679

and coiled about its fellow, would if straightened out, have a total length
somewhat greater than the entire animal. The external limb of the loop
has a slightly larger and more uniform diameter than the internal and its
walls have a firmer consistency, which increases as the muscular structure of
the ductus ejaculatorius is assumed. The difference however is slight
In one specimen the left epididymal loop passes ventrad to the right lateral
nerve of XIX and then bends forward dorsad to the nerve cord and
reaches to ganglion XVIII. Just before entering the prostate or atrial
cornu, the duct becomes constricted for a short distance. The atrium con-
sists of a very small common bursa, opening to the exterior and situated
entirely beneath the nerve cord, and of two large globoid-fusiform or
broadly ovate cornua, which diverge from beneath the nerve cord and
project prominently cephalad, laterad and dorsad within the limits of
somite XII. Their somewhat narrowed apices are joined by the sperm
ducts (Plate XLIX, fig. 10).

The ovarian sacs (Plate XLIX, fig. 10) have no anterior lobes (or at
least none are discernible in several dissections) and the two simple sacs
of irregular form lie in close contact in the ventral sinus between the nerve
cord and the sperm sacs. In the case where they exhibit the greatest
development, the left sac reaches to ganglion XVIII, the right to XVII.

Alimentary Canal. — The proboscis (Plate L, fig. 16) is stout, nearly
cylindrical but very slightly tapering; the anterior end is but little contracted
and truncate with fine denticulations on the margin. It reaches in the
retracted state from VII ai to XII aj and receives at its slightly enlarged
base the pair of thick ducts of the pharyngeal glands. These are a loose,
diffuse mass of unicellular glands occupying on each side the lateral por-
tions of somites XII to XIV and to a less extent of XL There is no
median lobe and the bundles of ducts from each side remain independent
of each other. A short, thin-walled oesophagus extends through XIII to
the stomach beginning in XIV.

The stomach is thin-walled throughout and resembles that of G. lineata
(Verrill) most closely, the caeca being better developed than is usual in
G. stagnalis. Six pairs of these caeca occur. The first, in XIV, are
very small and may be absent on one side, or otherwise asymmetrically
developed. In XV to XVIII are four pairs of slender caeca of simple
form, which (when empty) extend nearly half way to the margins of the
body. The pair of large, posteriorly directed ones arises in XIX and

680 PATAGONIAN EXPEDITIONS : ZOOLOGY,

extends to XXIV inclusive. The intestine has the usual four pairs of
lateral caeca in XX to XXIII inclusive, all of which are dorsad of the
large gastric caeca. The first three pairs are sacculated, the last smooth.
Each of the gastric and intestinal caeca arises directly over the correspond-
ing ganglion and, with the exception of the last gastric, is confined to the
limits of one somite.

This species must be exceedingly abundant throughout the region of
Mr. Hatcher's explorations, as the following list of the localities and num-
ber of specimens will show.

GLOSSIPHONIA SCUTIFERA (Blanchard).

The reproductive organs of Glossiphonia (Helobdella] sciitifera are inter-
mediate in character between those of G. duplicata and G. michcelseni in
that the vas deferens does not abruptly enlarge to form the sperm sac im-
mediately after turning caudad, as in the former, nor yet retain its tenuity
for several somites further back, as in the latter, but passes first into a
region of intermediate diameter before again increasing to the full size of
the sperm sac. That these differences are constant, seems certain from
the verification of the observation in repeated dissections. The ductus

MOORE: HIRUDINEA OF SOUTHERN PATAGONIA. 68 1

ejaculatorius is relatively longer than in G. duplicata and frequently makes
one or even two turns of a spiral in passing to the prostate cornua of the
atrium.

With the exception that the gastric caeca are considerably longer, the
alimentary canal differs in no important feature from that of G. duplicata.

There is never any appearance of subdivision of the annuli, although
the superficial annular lacunae are developed as in G. duplicata. In all of
the specimens examined by me the nuchal plate is thin and transversely
elongated, sometimes merely occupying a chink between VII aj and VIII ai.

Blanchard found this species to be very numerous in the collections
from the region bordering on the Straits of Magellan. In the uplands it
seems to be less frequent than some of its allies.

GLOSSIPHONIA SIMPLEX sp. nov.

(Plates XLIX, Fig. II ; L, Figs. 15, 23, 24.)

The nearest ally of this species is Glossiphonia lineata (Verrill), from
which it is distinguished by having somites III and IV uniannulate in-
stead of biannulate, and a single series of cutaneous papillae present on
every annulus instead of three series developed on the neural annuli only,
as in G. lineata.

G. simplex is broad, flat-bodied and thin, in which it contrasts greatly
with G. (Helobdelld] michcelseni R. Blanch., which in annulation and
anatomy it closely resembles. The annuli are very distinct, and the
margins, especially posteriorly, almost serrated. The oral sucker is small,
with thick margins and a rather deeply depressed center, in the anterior
part of which the large mouth is situated in somite III. The deeply pig-
mented eyes are in IV and are very conspicuous, owing to their large
size and the nearly color less areain which they lie. A median, slightly
enlarged area on annulus VIII ai represents a small nuchal gland, but
there is no nuchal plate, except in two specimens, in which it is very thin

682 PATAGONIAN EXPEDITIONS! ZOOLOGY.

and of nearly the form shown by G. scutifera. The posterior sucker is
relatively larger than in G. michcelseni and, unlike that species, faces
ventrad and extends further forwards. At the same time its posterior
margin is widely exposed from above. Its surface is roughened with
numerous minute papillae (Plate L, fig. 24). A somewhat irregular series
of small cutaneous papillae passes along the median dorsal line, usually
occurring on every annulus from the genital somite nearly to the anus.
Anterior to the genital pores they usually fade out and may be absent
from several of the preanal somites also. These papillae form a strictly
median series, not a broken double series as in G. lineata. They have a
nearly constant relative size on the three annuli of a somite, being longest
on a2 and smallest, and sometimes even wanting on ai.

MEASUREMENTS OF TYPE.
Total length, 9 mm.

Length to male pore, 2.5 mm.

Diameter of anterior sucker, 6 mm.
Diameter of posterior sucker, 1.2 mm.
Width of body at male pore, 2 mm.
Depth at male pore, .6 mm.

Greatest width (XVIII), 3.7 mm.
Depth at XVIII about, .8 mm.

Annulation. — I and II are coalesced. Ill and IV are uniannulate, the
latter containing the eyes. V is biannulate, the first annulus about as
long as the entire somite IV, the second (0,3} about three fifths as long.
The furrow V aila2 is sometimes faintly developed. VI is triannulate,
a2 generally, but not invariably, the longest.

The annuli of the complete somites, of which there are nineteen (VI to
XXIV), have, with the exception of the first and the last, which may vary,
a constant relative size ; a2 is the longest, ai the shortest ; ai has four
circular muscle-bands on the dorsal side, a2 and 0,3 have each five, except
that in most cases XXIV aj has but four. XXV is biannulate both dor-
sally and ventrally. XXVI and XXVII are uniannulate, the latter deeply
cut by the large anus. One distinct postanal annulus is differentiated
(Plate L, figs. 23 and 24).

Unlike most of the material in this collection, which was not suitably

MOORE: HIRUDINEA OF SOUTHERN PATAGONIA. 683

preserved for the purpose, many examples of this species exhibit a part of
the dorsal sensillae. In no case could the full number be detected on any
one somite and it is possible that the dorso-median series may be wanting.
At any rate the pair most median in position are separated by a wide
interval, equal to about half the width of the body. Plate L, fig. 24, shows
their arrangement on somite XXIV of an individual in which they were
especially prominent.

Pigmentation. — The color above is a pale brownish, with a broad
median dark area (equal to two thirds of the width of the body) marked
by twenty-four fine longitudinal lines of black pigment cells, which corre-
spond to as many intermuscular intervals. The two most mesial of these
are much heavier than the others and tend to unite across the median line.
All of these lines, and consequently the area, tend to fade out both ante-
riorly and posteriorly. More superficial than the longitudinal striae are
small irregular blotches and transverse dashes which lie between the cir-
cular muscles and are more or less thickly scattered over the entire dorsal
surface from margin to margin, except anteriorly, where they are very few,
and further forward altogether absent. These spots give to the dorsum
a speckled appearance not unlike what is seen in many examples of G.
scutifera. Of course some individuals are lighter, some darker. Many
examples have two or three large irregular whitish spots, from which pig-
ment is nearly or quite absent, in the posterior part of the body. A some-
what unusual feature in members of the genus is the presence on the
ventral surface of submarginal series of irregular, more or less confluent
dark spots, forming a band on each side. They are confined to the middle
third of the body.

Reproductive Organs. — The genital pores are separated by a single
annulus, the male being at XII aila2, the female XII a2laj. There are
six pairs of testes arranged as in G. duplicata. The vas deferens is dorso-
laterad of the testes and is met by the six delicate vasa efferentia, which
arise from the dorso-lateral aspect of the testicular walls. After reaching
somite XII the vas bends back into a long epididymal loop as in G. dupli-
cata, but, instead of becoming enlarged at once to form the sperm sacs,
as in that species, it reaches, without any change in its diameter or the
character of its wall, as far caudad as XVI or XVII, at which point it
abruptly passes into the sperm sac. The latter may extend as far as
XX, and the anterior end of its efferent limb becomes more or less coiled

684 PATAGONIAN EXPEDITIONS! ZOOLOGY.

and looped in XII or even extends into XL The atrium and ductus
ejaculatorius exhibit no features requiring special comment, which is
true of the ovaries also (Plate L, fig. 15). The collection includes one
specimen of 8 mm., bearing eggs arranged in a compact group at the
widest part of the body. Others exhibit indications of having recently
borne eggs or young.

Alimentary Canal. — The pharynx is about as stout as that of G. lineata,
and when retracted reaches from VIII to XII. Its free end is provided
with muscular denticulations. In XIII the thick ducts of the pharyngeal
glands open into its posterior end. These ducts are provided with a
stout muscular sheath, are single on each side and lack any cross connec-
tion. The glands consist of a few cells which are individually of larger
size than in G. duplicata and are distributed sparingly over somites XI to
XV or even beyond. There are usually only five pairs of gastric caeca,
the first four of which are simple and of nearly equal size, the fifth, which
arises in XIX, is somewhat spacious and reaches XXII. The intestinal
caeca are four pairs, alternately larger and smaller, and, with the excep-
tion of the last, curve somewhat cephalad above the last pair of gastric
caeca (Plate XLIX, fig. n).

GLOSSIPHONIA MICH^ELSENI (Blanchard).

(Plate L, Figs. 13, 14.)

Among the peculiarities of the reproductive organs (Plate L, fig. 14)
the following are noteworthy. There are epididymal loops (sperm sacs)
formed by the vasa deferentia as in G. duplicata, G. stagnalis, etc., and
usually reaching beyond ganglion XVIII. In one respect they differ
strikingly from those of G. duplicata and as closely resemble G. simplex,
viz., the vasa deferentia after turning remain of extreme tenuity until
reaching XV or XVI, that is, for about half the length of the loops, and
then suddenly enlarge into the sperm reservoirs. This is true of all of a
considerable number dissected. Before entering the prostates, the duct
is thrown into several deep folds, which extend anterior to the atrium even
into somite XI.

In the form of the alimentary canal (Plate L, fig. 13), as indeed in
many other respects, this species closely resembles Glossiphonia nephe-
loides (Graf.) (= G. elongata Castle), a not uncommon species in Penn-
sylvania, New Jersey, and Massachusetts. A striking difference in the
digestive tract, however, is the entire absence of the large gastric caeca,
which in other Glossiphoniae arise in XIX, and in G. nepheloides extend,
according to Castle, through two somites.

The mouth, which is of remarkably large size, is in somite III. The
pharynx, which, when retracted, reaches from VIII to a point just caudad
of the male pore, is stout and may be extended to an unusual distance,
in some cases to nearly one third the length of the body. It is nearly
cylindrical, but tapers somewhat abruptly at the free end, which is termi-
nated by nine larger muscular denticulations, arranged in three sets of
three each and alternating with three smaller ones. Three longitudinal
muscular ridges continue these for the entire length of the pharynx and
give to its lumen the usual triangular form. They terminate at the point
of entrance of the ducts of the pharyngeal glands in XII or XIII. As
in most small glossiphonids of the Helobdella group, these glands are
strictly paired. In this species they consist of a very few unicellular glands
of large size arranged in a loose group confined mainly to XII and XIII,
though occasionally extending somewhat into the immediately adjacent
somites. The ducts are in one pair, of large size and strongly muscular.

A short oesophagus gradually widens into the thin-walled, somewhat

spacious stomach which reaches from XIV to XIX inclusive. The stomach
increases in diameter to about XVII, behind which a constriction occurs,
followed by a rather conspicuous sacculation in XIX, probably represent-
ing the posterior gastric caeca which, however, do not extend at all caudad.
Indeed there are no distinct gastric caeca whatever. Four pairs of short,
rather wide intestinal caeca are crowded into XXI and XXII and are fol-
lowed after a constriction by a somewhat bulbous dilatation.

G. michcelseni is represented by a larger number of specimens than
any other of the six species included in the collection.

HEMICLEPSIS TESSELLATA (Miiller) Veydovsky.

A single individual, which is in nowise distinguishable from this well-
known European species, was collected on the Rio Chico.

In demonstrating the identity of Theromyzon fallens Philippi with this
species Blanchard has already shown that its range extends in South
America as far south as Chili. Inasmuch as it is widely distributed,
though by no means common, in North America, it may now be expected to
occur generally over the American continent. Hemiclepsis tessellata is an
excellent example of the wide distribution which some species of leeches

MOORE I HIRUDINEA OF SOUTHERN PATAGONIA. 687

have attained. An equally notable case is the Glossiphonia stagnalis
(Linn.). Blanchard has recorded this species from Paraguay1 and Chili.2
I have specimens collected by Mr. Trevor Kincaid in Alaska and it
abounds in all parts of the United States, Canada and Europe.
