A FURTHER CONTRIBUTION TO THE ICHTHYOLOGY OF
VENEZUELA
By Leonard P. Schultz
This paper is the third report on the collections made by me in
Venezuela during 1942 and those made by the U. S. S. Niagara in the
Gulf of Venezuela during 1924 and 1925. Other miscellaneous small
collections were included when they were found in the National
Museum, as were others kindly lent for study and report. To the
following I express my sincere gratitude for their kindness and coop-
eration: Dr. Reeve M. Bailey, Museum of Zoology, University of
Michigan, lent some of the Bond Venezuelan collections made in
1938-40. Dr. Karl P. Schmidt and Marion Grey, Chicago Natural
History Museum, lent the W. H. Osgood specimens taken in the
Maracaibo Basin. Dr. William Beebe, New York Zoological Society,
lent his collections from the vicinity of Caripito. Isaac Ginsburg,
U. S. Fish and WildUfe Service, identified all the specimens of Gobiidae
and Eleotridae in the above-mentioned collections. Dr. Samuel F.
Hildebrand, of the same Service, while working up his collections of
marine fishes from Panama, identified several species of Venezuelan
marine fishes and aided in many other ways. Luis Rene Rivas very
kindly checked the spelling of the Spanish names of fishes and of the
localities.
My interest in Venezuelan ichthyology began in the winter of 1941-
42 when, at the invitation of Dr. GuiUermo Zuloaga, assistant chief of
explorations, Creole Petroleum Corp., Caracas, I undertook to study
802207 — i9 1 1

and make collections of fishes in the Maracaibo Basm of Venezuela.
This work continued from February through May of 1942. I pro-
ceeded to Venezuela under the auspices of the Smithsonian Institution
and of the United States Department of State and was a guest there
of the then Standard Oil Co. of Venezuela, and of the Lago Petroleum
Corp., Lago de Maracaibo. To the officials of these companies I
again express my gratitude for their full cooperation.
My first report on these collections was entitled "The Catfishes of
Venezuela, with Descriptions of Thirty-eight New Forms," published
February 11, 1944, in the Proceedings of the United States National
Aluseum, volume 94, pp. 173-338, 5 figs., 14 pis. In this report is
given an itinerary of my travels in Venezuela along with a Ust of col-
lecting stations. The second report, "The Fishes of the Family
Characinidae from Venezuela, with Descriptions of Seventeen New
Forms/' was published September 6, 1944, in the same Proceedings,
volume 95, pp. 235-367, 27 figs.
A summary of my Venezuelan collections during 1942 reveals that
the largest number of species taken in one locality was 45 from the
Rio Negro. The next largest collection numbered 35 from the Rio
San Juan (Motatdn system), 33 from the Rio San Pedro, and 33 from
the Rio Socuy. In the stream systems where fairly representative
collections were made the following number of species were preserved:
Rio Motatdn, 54; Rio Negro, 45; Rio Palmar, 41; Rio Socuy, 33; Rio
Ap6n. 31; Rio Machango, 31; and Rio Chama, 10. There were 56
species from Lago de Maracaibo and along the coast of Gulf of Vene-
zuela to Cafio de Sagua. Altogether my collections contained 140
species from the Maracaibo-Gulf of Venezuela Basins; 25 from Rio
Gudrico and Rio Torbes; 1 from Rio Tuy system; and 3 species com-
mon to the first two basins, a total of 169 species and subspecies that
I collected.
The present report is not intended to be comprehensive in scope,
since there are not yet sufficient collections of fishes from Venezuela
to justify the writing of a descriptive catalog. It is rather a report on
several collections of Venezuelan fishes, with descriptions of new
species, and represents only the beginning in the study of the fish
fauna of Venezuela. It is highly desirable that much more extensive
collections be made in all the stream systems and lake basins of the
country.
Unless otherwise indicated all collections were made in 1942 by
L. P. Schultz in the Maracaibo Basin. Abbreviations used to indicate

ICHTHYOLOGY OF VENEZTJELA — SCHULTZ 3
GEOGRAPHY AND CLIMATE OF THE MARACAIBO BASIN
Lago de Maracaibo has an average depth of about 100 feet (maxi-
mum 34 meters, or 11 iK feet) and a soft muddy bottom. From its
southern end to the beginning of the channel at Punta de Pahnas,
south of the city of Maracaibo, it is 154.5 kilometers, or 95.8 miles, long;
the length of the channel from Punta de Palmas to Punta Vigia at
entrance into El Tablazo is about 39% kilometers, or 24.3 miles; and
from Punta Vigia across El Tablazo to the entrance into the Gulf of
Venezuela at Castillo de San Carlos is 20.75 kilometers, or about 12.9
miles, making a total length from the Gulf of Venezuela to the southern
end of the lake of 214.9 kilometers, or about 133.25 miles. The
greatest width of the lake is about 121 kilometers, or 75 miles. The
long axis of the lake is almost directly north-south.
High mountain ranges enclose the T^Iaracaibo Basin on all sides
except the north. The Sierra de Perija forms the western divide,
whereas the Cordillera Oriental occurs at the southwestern side, and
along the southern and southeastern side the lofty Cordillera de Los
Andes, with Pico Bolivar reaching to a height of 5,005 meters. Another
range of high hills and mountains forms the eastern rim of the basin.
The northern end of the l\Iaracaibo Basin is semidesert, contrasting
sharply with the tropical jungle at the southwestern and southern ends,
where the rainfall is very great along the eastern slopes of the Cordil-
leras de Perijd and Oriental even during the dry season.
During 1941 the Maracaibo Nautical School recorded the following
monthly average temperatures and total monthly rainfall at Mara-
caibo, as published February 14, 1942, in the Maracaibo Herald:
January, 81° F., 4 mm.; February, 83° F., 6 mm.; March, 82° F., no
rainfall; April, 84° F., 16 mm.; May, 85° F., 144 mm.; June, 85° F.,
1 1 mm. ; July, 85° F., 9 mm. ; August, 85° F., 3 mm. ; September, 85° F.,
38 mm.; October, 83° F., 26 mm.; November, 84° F., 68 mm.; De-
cember, 83° F., 5 mm. The rainfall thus totals 330 mm., or 13 inches.
The average monthly rainfall for the eastern shore at LaguniUas is
given below for a period of 14 years (1928-1941), from information
furnished by the Lago Petroleum Corp. These records are in inches,
with minima and maxima in parentheses. January, 0.22 (0.00 to
1.33); February, 0.26 (0.00 to 1.08); March, 0.69 (0.00 to 2.09); April,
1.59 (0.11 to 5.41); May, 4.47 (1.49 to 9.21); June, 3.20 (1.07 to 7.72);
July, 3.81 (0.87 to 11.71); August, 4.05 (0.76 to 8.91); September,
4.89 (0.94 to 11.90); October, 6.21 (2.62 to 11.53); November, 3.52
(0.45 to 8.78); December, 0.80 (0.00 to 1.78). Total average rainfall
33.98 inches, with a minimum of 18.40 in 1939 and a maximum of
51.01 in 1933. These data indicate the increase in amount of rainfall
southward in the Maracaibo Basin. Undoubtedly the heaviest rain-
fall occurs at the southwestern corner of the Basin where the jungle is
4 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 99
heaviest and where the big rivers empty large quantities of muddy
water into the lake.
During the dry season from December through March the trade
winds are strongest, blowing from the north and northeast through the
channel and lengthwise across the lake, becommg strongest in the
afternoon, late evening, or early part of the night. The surface water
of the lake apparently has a counterclockwise rotation in the southern
two-thirds of the lake.
The specific gravity of the water was taken by means of a saU-
nometor, and the following readings were recorded: Gulf of Venezuela,
1.021 at mouth of Cafio de Sagua on incoming tide; El Tablazo and
at Maracaibo Yacht Club, 1.006; Lago de Maracaibo, 2 km. off
Lagunillas, 1.004; and at southwestern end of the lake 2 Ian. off Rio
Concha, 1.002. The turbidity of the water may increase its specific
gravity a httle at the southern end of the lake. Undoubtedly the
deeper waters of this lake are salty.
FISHERIES OF THE GULF OF VENEZUELA-MARACAIBO BASIN
The fishes of the Gulf of Venezuela and Lago de Maracaibo are
almost untouched commercially as compared with the great fisheries
of the North Sea and those of the Atlantic and Pacific coasts of North
America. I believe the fisheries of Venezuela cannot be greatly
developed until more modern fishing equipment, including quick-
freezing refrigeration and power fishing boats with refrigeration
equipment, are used extensively. Such equipment would permit
fishermen to go farther, stay out longer, and still be able to bring back
desirable fishes to the market without deterioration and spoilage.
These bodies of water contain an abundance of anchovies, completely
unexploited and almost unkno\vn to the fishermen. Some are small,
but others reach a length of nearly a foot, and all are delicacies. A
special type of net would have to be developed for their capture.
Other species, I found, such as mullets (lisa), various catfishes (bagre),
bocachicas and p^mpanos (Characinidae), robalos (Centropomidae),
kingfishes and Spanish mackerel (carite or carite sierra), pdmpanos
(jurel), leatherjackets (zapatero de mar and palometa de lago), snap-
pers (pargos), grunts (roncos), groupers (meros), sargos, croakers
(corvinas), and moj arras de rlo, are common market fishes sold either
fresh or salted. Further investigation over a period of a year would
probably have revealed other fishes in the Maracaibo Market.
This much was obvious: That new fishing methods should be tried,
such as the beam-trawl, otter-trawl, fish traps, purse seines, and other
fishing gear, depending on the bottom and depth of water and kind of
fish desired. Now that sharks are in demand, shark fishing sbould be
attempted in these waters. With the great abundance of blue crabs
in the lake a valuable fishery could be developed.
ICHTHYOLOGY OF VENEZUELA — SCHULTZ 5
Considerable destruction of fish life is undoubtedly caused by oil
wells in the lake near the eastern shore for a distance of about 80 km.
Far out into the lake the surface is more or less covered with a film of
oil. At times and in certain places the petroleum forms a thick scum
on the surface, and as the volatile portions evaporate the tarry residue
becomes thicker and thicker, finally settling into the water in tiny
to large globules. These, while suspended in the water, drift with the
wind across the lake and saturate the beaches, covering the aquatic
plants and shore vegetation and the bottom with a layer of petroleum,
making existence for fish life very hazardous. Unless this oil leakage
can be stopped the northern end of Lago de Maracaibo, at least, may
become rather barren, the sources of fish-food production exterminated,
and the possibilities of extensive and valuable fisheries in the future
greatly reduced.
These great shallow bodies of water with large rivers emptying into
them should be considered one of Venezuela's great natural resources.
Together with the Gulf of Paria and the Rio Orinoco and its delta they
are capable of producing many millions of tons of fishery products
annually. If they were developed and properly controlled a maxi-
mum yield would result from a minimum of fishing effort. Such a
balanced condition between fishing and natural reproduction of fishes
can be obtained only through unbiased studies by adequately trained
fishery biologists and ichthyologists, who would recommend the
proper controls for the various fisheries.
DISTRIBUTION OF FRESH-WATER FISHES
In this report the fresh-water fish fauna of Venezuela is considered
as including those families whose genera and species are predomi-
nantly permanent inhabitants of fresh waters and which, except for
the Cyprinodontidae, enter brackish waters only more or less as
stragglers. Such families are: Pimelodidae, Callophysidae, Auchen-
ipteridae, Ageneiosidae, Bunocephahdae, Cetopsidae, Pygidiidae,
Doradidae, Callichthyidae, Astroblepidae, and Loricariidae (all
catfishes), and in addition the Characinidae, Sternarchidae, Gymno-
tidae, Electrophoridae, Cyprinodontidae, Poeciliidae, Synbranchidae,
Polycentridae, and Cichlidae.
The relationships and derivation of the fresh-water fish faunas of the
various stream systems of Venezuela cannot be worked out at this
time with any degree of certainty because the various species of fishes
occurring in many of the drainage systems are as yet little known or
unknown.
A list of drainage basins or stream systems of northern Venezuela is
presented below to aid in the interpretation of this report. Each
indentation indicates that the body of water is tributary to the one
under which it is indented.

During the preparation of a working distributional chart or table
of the form published by Eigenmann,* I came to the conclusion, after
several days of labor, that such a chart, instead of giving a clear picture
of the actual distributional relationships of the fish fauna for the
various basins, instead presents a picture of the amount of collecting
that has been done in these various basins, and the care mth which
the material was studied or reported upon. For instance, Eigenmann's
report on the fresh-water fishes of British Guiana has a large number
of new species, many based on a single specimen. There is no com-
parable work on the fauna of the Orinoco system or even the Amazon.
Thus in such charts the Guianas appear to have a fauna greatly in
excess of that of the Orinoco, because the fishes of the latter great
river system have never been thoroughly investigated. The Orinoco
system, with its direct connection through the Kio Negro with
the Amazon, should have a fauna more extensive than that of the
Guianas. Therefore, I concluded to confine my remarks on dis-
tributional relationships between drainage basins to general state-
ments, awaiting the time when these faunas are better known.
The fresh-water fish fauna of the Maracaibo Basin is distinctive as
to its species, since nearly every one except those living in river
mouths is a little different structurally from those in adjoining basins
and may be subspecificaUy distinct. When taken as a whole it appears
that this fauna is almost as closely related to that of the Orinoco as
to that of the Magdalena, especially those species inhabiting the upper
courses of the rivers. The lowland species of the Maracaibo Basin
appear to be very similar to those of the Magdalena, and some are the
same species. Undoubtedly during the mountain building around the
3 Lago de Valencia is said to have been much larger at one time and to have had an outlet to the Orinoco
system through the Rio Pao.

western, southern, and southeastern sides of the Maracaibo Basin,
stream capture has played some part in causing crossover of species
among the Orinoco, Magdalena, Catatumbo, Santa Ana, and Chama
Rivers. Just how extensive this may be must await extensive col-
lecting in the headwaters of those rivers. In general, the genera
occurring in the headwaters have a much more extensive distribution
than those in the lower courses and in the lowlands. All the following
genera of the Maracaibo Basin occur in the lower courses of the rivers
and are distinctive for that Basin and so far have not been found
outside of it: Sovichthys, Perrunichthys, Hoplomyzon, Tridensimilis,
Doraops, Saccoderma, Creagrutops, and Hubbsichthys. In a recent
letter Cecil Miles reports finding Dupouichthys in the Magdalena
system.
In view of the fresh-water nature of the southern part of Lago de
Maracaibo, the fauna of all the rivers tributary to this lake may be
expected to have the same species, with some distinctive ones isolated
or restricted to the rapid or torrential parts of the rivers. This
appears to be true so far as my collections from this Basin are con-
cerned, but as yet no good collections have come from the headwaters
of the Catatumbo, Escalante, or Santa Ana Rivers, among others.
Undoubtedl}^ the number of species \^dll be nearly doubled when the
Basin including the lake itself, is thoroughly searched and studied.
The numerous coastal streams emptying into the Caribbean Sea
along the north coast of Venezuela are almost unexplored ichthy-
ologically. "When studied they should present another interesting
chapter in Venezuelan ichthyology. These streams should be rich
in cyprinodonts and other genera and species of the lowlands.
The fish fauna of the Valencia Basin is strikingly like that of the
Rio Gudrico, with which it was once connected, but as in most of the
stream systems it contains distinctive species not yet reported from
elsewhere.
DISTRIBUTION OF MARINE FISHES
The specimens of fishes forming the basis of this report indicate in
general that the marine fishes of Venezuela form a part of that fauna
which extends from the Gulf of Mexico, Caribbean Sea, and West
Indies southward along the coast of Brazil to the mouth of the Rio La
Plata. Certain elements of that fauna, as far as is known at present,
appear to be restricted to such bodies of water as the Caribbean Sea,
Gulf of Venezucla-Lago de Maracaibo, and Gulf of Paria. Un-
doubtedly as further collecting is done the ranges of these and many
other species will be greatly extended.
Lago de Maracaibo is a great body of water, brackish at its northern
end, probably salty in its deeper parts, but at least the great southern
end with its many canos is fresh at the surface. This condition has
made possible the infiltration of marine fishes from the Gulf of
ICHTHYOLOGY OF VENEZUELA — SCHULTZ 9
Venezuela and of fresh-water species of fishes in the southern portion
where the great rivers enter. Thus, Lago de Maracaibo contains an
interesting mixture of marine, brackish, and fresh-water species.
Although the fish fauna of the lake is not adequately known at present,
enough knowledge has accumulated to indicate that the marine and
fresh-water species have adapted themselves to live in this body of
water, and in so doing some have changed a little structurally. These
have evolved into more or less separate biological units, recognized in
this report as either species or subspecies.
Those families of fishes that are usually considered marine by
ichthyologists and that have representatives that have been found in
Lago de Maracaibo and in the Rio Orinoco are discussed below.
In Lago de Maracaibo, sharks, sawfishes, and large stingrays were
reported, but I did not have an opportunity to fish for these. Sharks
are caught by fishermen as far south as off the mouth of the Rio Santa
Ana. The occurrence of sharks in fresh-water lakes with access to the
sea is not confined to Lago de Maracaibo. In Lake Nicaragua
Eulamia nicaraguensis occurs in abundance and reaches a large size.
Among the elasmobranch fishes the stingrays of the family Dasyati-
dae have been most successful in evolving permanent species in South
American fresh waters. The genus Potamotrygon has one species in
the Rio Orinoco and the Guianas, another in the Rio Atrato, Rio
Magdalena, and Maracaibo Basins, and others farther south. These
fresh-water stingrays occur far upstream, the females when caught
often carrying young.
Several other marine families of fishes have representatives in fresh
or brackish waters. The anchovies, or Engraulidae, have a few
species occurring regularly in the fresh waters of the Rio Orinoco and
of the Lago de Maracaibo and its tributaries. These belong to the
genera Anchoa and Lycengraulis in Venezuela.
The tarpon, Tarpon atlanticus, and the tenpounder, Elops saurus,
are regular inhabitants of Lago de Maracaibo and in the lower courses
of its large tributary rivers. The needlefishes, family Belonidae, were
represented by Strongylura timuacu. The females, when taken at the
southern end of Lago de Maracaibo, contained mature eggs that
flowed from the vent with gentle pressure. This needlefish was taken
far up the Orinoco system in the Rio Apure. The Hemiramphidae, or
halfbeaks, were represented by Hyporhamphus roberti in Lago de
Maracaibo.
Two genera of pipefishes, or Syngnathidae, namely Oostethus and
Pseudophallus, were found in the lower courses of rivers, probably in
brackish water. Soles of the family Bothidae, genus Citharichthys, and
tonguefishes, family Achiridae, of the genera Hypoclinemus, Achirus,
and Trinectes, regularly occm- in brackish water, a few venturing even
into fresh waters.
10 PROCEEDESTGS OF THE NATIONAL MUSEUM vol.99
I found the Atheriiiidae, or silvcrsides, represented by a fresh-water
species in Lago de Maracaibo, and another species in the northern end
where the water is brackish. Lago de Valencia also has a species of
silverside.
The mullets, or Mugilidae, are represented by Agonostoma monticola
in Venezuelan fresh waters. Mugil curema and M. brasiliensis are
found in brackish water in abundance, along with ilf . trichodon. I took
M. curema at the southern end of Lago de Maracaibo in fresh water.
The robalos, family Centropomidae, are abundant in brackish, salt,
and fresh waters, probably most abundant in brackish waters.
In the family Carangidae the leather jacket, Oligoplites palometa,
occurred in fresh, brackish, and salt waters. It is abundant in Lago de
Maracaibo at the southern end in fresh water.
The mojarros, or carpetas, family Gerridae, represented by the
genera Eucinostomus and Diapterus, were abundant in the brackish
waters of Lago de Maracaibo and in coastal lagoons. Two species,
Eucinostomus argenteus from the Rio Apure and Diapterus plumieri
from the Rio Concha, were from fresh water.
The Ariidae are the only family of nematognaths, or catfishes,
predominately living in salt and brackish waters. In my report on the
catfishes of Venezuela I used the family name Bagreidae, which may
be unfortunate since there is another family name spelled very simi-
larly. I now use Ariidae in its place. Several genera and species of
these marine catfishes occur regularly in both marine and brackish
waters in abundance in Lago de Maracaibo and undoubtedly in the
lower Rio Orinoco.
In the croaker family, Sciaenidae, Plagioscion and Pachyurus may be
considered fresh-water genera. They are found in the Rio Orinoco
but are not yet reported from the Maracaibo Basin. The corvina,
Cynoscion maracaiboensis, is a brackish-water species probably con-
fined to Lago de Maracaibo.
Several members of the Gobiidae and Eleotridae occur in brackish
waters, such as the genera Gobiomorus, Garmannia, Evorthodus,
Bathygobius, GobioneUus, and Sicydium, whereas the genera Micro-
philypnus, Gobiomorus, and Sicydium have been taken in fresh water.
Among the clingfishes, family Gobiesocidae, the only species occur-
ring in fresh water is Gobiesox cephalus.
I found the puffer, Sphoeroides testudineus, family Tetraodontidae,
very abundant in the brackish waters near Maracaibo, whereas S.
eulepidotus was very rare, but a single small specimen was collected in
brackish water.
Gordon Gunter (Amer. Midi. Nat., vol. 28, No. 2, pp. 305-326,
1942) presents lists of fishes occurring in both fresh and salt waters of
North and Middle America. No such list has been prepared for
South America.
ICHTHYOLOGY OF VENEZUELA — SCHULTZ 11
HISTORY OF ICHTHYOLOGY IN VENEZUELA
As far as I have been able to find the fresh-water stingray of the KIo
Meta in Venezuela, one of the most dreaded aquatic inhabitants, is
the first fish of that country to be figured and described. It appeared
in a paper by Rouhn (1829), but it was not given a scientific name.
The first scientific contribution appears to be that by two other
Frenclimen, Cuvier and Valenciennes, who included in their famous
work "Histoire Naturelle des Poissons" descriptions of new fishes,
published from 1828 to 1849. M. Plee apparently sent specimens to
the Paris Museum from the vicinity of Maracaibo and Lago de Mara-
caibo, Puerto Cabello, and La Guaira, as well as from other locahties
in the West Indies. The few species described by these French
authors represented the known ichthyological fauna of the Maracaibo
Basin for a period of 75 years, until after the turn of the century.
Although Boulenger in 1903 and Regan in 1903 and 1905 described
a few new fishes from the Maracaibo Basin and from Venezuela, no
extensive collecting of fresh-water fishes was done in the Maracaibo
Basin until Dr. Franklin F. Bond took fair series during 1938 and
1939, and I made extensive collections during February tlu-ough May
of 1942.
Numerous authors have reported on small collections of Venezuelan
fishes from outside the Maracaibo Basin, but the fish fauna of the
Basin itself has remained an ichthyological incognito until the present.
Even now it cannot be said that the fish fauna of Venezuela is well
known; perhaps it is only half known, for there are no extensive collec-
tions from any of the major tributaries of the Orinoco system. The
coastal rivers from the Gulf of Paria to the Ivlaracaibo Basin are
practically unknown ichthyologically. New and unusual forms of
fishes should turn up as experienced collectors begin to work in these
and other rivers of Venezuela. Even with the collecting in the
Maracaibo Basin the two major rivers, the Catatumbo and the
Santa Ana of that Basin, as well as the lake itself, remain practically
untouched. My work and that of others should be considered only
preliminary, for years of collecting must be done before the fishes of
Venezuela are well kno"\vn.
The following minor contributions on Venezuelan fishes should be
mentioned: Rudolph Kner m 1854 and 1859 and Wilhehn Peters in
1860, 1868, and 1877 reported on early studies. Peters's 1877 report
was based on specimens collected by Dr. Carl Sachs in Venezuela on
his trip from September 27, 1876, to June 28, 1877. Albert Giinther,
1859-1866, recorded a few species of fishes from Venezuela, mostly
from Puerto Cabello, La Guaira, and the vicinity of Caracas. An-
other early author, Adolfo Ernst (1877), pubhshed a book that devoted
three pages to fishes. Two other early authors, Charles Liitken
12 PROCEEDESTGS OF THE NATIONAL MUSEUM vol. 99
(1874) and F. Mocquard (1886, 1889), have referred to or described
a species or so of fishes from Venezuela.
The outstanding contributions by Franz Steindachner, from 1868
to 1917, were based largely on specimens from the Orinoco system.
His most important work, as far as Venezuela is concerned, appeared
in 1910 and 1917.
Jacques Pellegrin (1899) reported on a small collection of fishes
from the Rio Apure system and wrote other papers from 1903 to 1912
that included Venezuelan records.
During more recent years other authors have mentioned a few
species of fishes. Most important among these is Jan Metzelaar's
1919 report on the marine fishes taken by Dr. Boeke largely from the
Venezuelan locahties of Puerto Cabello, La Guaira, and Guanta.
Dr. Carl L. Hubbs in 1920 described a new goby from near Macuto.
Francesca La Monte in 1929 named two fishes from Mount Duida.
Ernst Ahl in 1928 and Enrico Tortonese in 1939 recorded a few fishes
from Venezuela.
Although Dr. Carl H. Eigenmann and his coauthors published a
large series of papers on South American fishes, these give only casual
mention of Venezuelan localities except in a single paper (Eigenmann,
1920a). Dr. A. S. Pearse in 1919 and 1920 reported mostly on the
ecology of this same collection from the Valencia and Rio Tuy Basins.
Henry W. Fowler, although mentioning Venezuelan fishes in several
of his numerous papers, made two reports (1911, 1931) on collections
made in Venezuela. The specimens on which Fowler based these
reports came from northeastern Venezuela from streams tributary to
the Gulf of Paria and from the lower Orinoco system.
Dr. George S. Myers, who has written numerous short papers on
South American fishes, has referred to Venezuelan localities in several
published from 1924 to 1944. He devoted a major part of the following
contributions to Venezuelan fishes: 1927, "Descriptions of New South
American Fresh-water Fishes Collected by Dr. Carl Ternetz"; 1928,
"New Fresh-water Fishes from Peru, Venezuela, and Brazil"; 1932,
"A New Genus of Funduline Cyprinodont Fishes from the Orinoco
Basin, Venezuela"; 1935, "Four New Fresh-water Fishes from Brazil,
Venezuela and Paraguay." His latest and largest contribution on
Venezuelan ichthyology appeared in 1942 under the title "Studies on
South American Fresh-water Fishes, I," in which he described some
new species of fishes from the Maracaibo Basin, the first since the
time of Cuvier and Valenciennes. The collections of Venezuelan
fishes on which this paper was based were made largely by Dr. F. F.
Bond during 1938-1939, but the bulk of Bond's fresh-water fishes are
stiU at Stanford University and as yet not reported upon.
Codazzi (1940) published a 3-volume work and mentioned common
ICHTHYOLOGY OF VENEZUELA — SCHULTZ 13
names of fishes in volume 1, pp. 259-267. His descriptions under each
name indicate unfamiliarity with practically all the fishes discussed.
The book by Eduardo Rohl (1942) devotes pages 353 to 413,
figures 172 to 230, to fishes. Although it is intended for popular use,
the author used a most antiquated scientific terminology, based in
large part on papers written over half a century ago. However,
Eohl's book has been a valuable source of common names of Vene-
zuelan fishes in spite of its other shortcomings from an ichthyological
standpoint. It contains numerous records of marine fishes for
Venezuelan waters found nowhere else.
My own contributions on Venezuelan fishes began in 1943, based
on my collections made in 1942. In addition to these I have had at
my disposal other collections that have been included in this and in
previous reports. The first were a few specimens collected by Lyon
and Robinson at Macuto, Venezuela, August 1 and 2, 1900, and given
by them to the United States National Museum. Next, the Chicago
Natural History Museum kindly lent for report and study a small
collection made by Dr. W. H. Osgood in 1911 at Encontrados and
other localities in the Maracaibo Basin, along with specimens collected
in 1920 by Osgood and Conover. I also found in the national col-
lections a few specimens collected by Dr. Henri Pittier in 1923, and
by Dr. Arnoldo Gobaldon in 1935, probably in connection with the
work of the International Health Board. Other fresh-water fishes
from the vicinity of Caripito, collected by Dr. William Beebe in 1942,
were kindly lent for study and report. Dr. Beebe has published a
few papers on his Caripito expedition in Zoologica beginning in 1942.
Almost the only marine fishes from Venezuela that I have had for
study were those collected by the U. S. S. Niagara in the Gulf of
Venezuela during 1924-1925, through the efforts of Capt. P. P.
Blackburn, who sent them to the former U. S. Bureau of Fisheries.
Later they were transferred to the National Museum through the
courtesy of Dr. S. F. Hildebrand, who had reported on the anchovies
from this collection in 1943. In addition I was able to obtain a few
marine fishes during my 1942 Venezuelan trip.
The history of Venezuelan ichthyology may best be gained by a
glance at the section "Literature Containing References to Venezuelan
Fishes" at the end of this paper.

TAXONOMIC SECTION
Class ELASMOBRANCHII
Subclass Selachii
Superorder Selachoidea: Sharks and Rays
The sharks and rays may be distinguished from the bony fishes by
the differences in the number of external gill openings, in sharks 5 to 7
on each side, whereas in the bony fishes there is a single external gill
opening. The gills of bony fishes are covered by the operculum. The
upper lobe of the caudal fin is longest.
The sharks of Venezuelan waters are fully described and keyed out
to species in "Fishes of the Western North Atlantic" by Dr. H. B.
Bigelow and William C. Schroeder (Mem, Sears Foundation Mar.
JRes. No. 1, pp. 59-576, figs. 6-106, 1948). It is not considered neces-
sary here to report upon them in detaU, since all my Venezuelan
specimens were studied by those authors.

Superorder Hypotremata
Order BATOIDEA: Rays and Skates
This order includes those elasmobranch fishes that have a greatly
depressed head and body, with the pectoral fins greatly expanded and
continuous with the head and body, forming more or less of a disk.
The five gill openings occur on the ventral or under side of the head,
in front of which is the mouth. The snout is depressed and forms
part of the disk or projects forward.
Suborder Rajiformes
Family PRISTIDAE: Sawfishes
This family is characterized by the presence of a long bladelike
snout, the sides of which have large projecting "teeth" or spines set in a
socket. In Venezuelan waters these number from 14 to 30 or a few
more.

For pectinatus, from the Gulf of Venezuela: 28-29; from Lake

Family DASYATIDAE: Stingrays; Rayas
This family may be recognized by the presence of a "sting" or sharp
serrated spine, sometimes two of them, on the dorsal surface of the tail.
The pectoral fins are continuous with the snout in this family, the snout
scarcely projecting or not projecting in front of the general outline
of the disk-shaped body.
Many persons and some uninformed naturalists have the opinion
that stingarees, as they are commonly called, do not have a poisonous
sting. Those who have studied these fishes and have had personal
experience with them are certain that the "sting" is highly venomous.
Before I cite cases of persons who have been jabbed by the spine of a
stingray, I shall acquaint the reader with these fishes and the nature
of their sting or spines.
The stingaree is one of the rays, fishes related to the sharks and
greatly resembling them in structure. In shape, however, they are
flattened and disk-shaped and have a long tail. The rays, which bear
a long sharp spine, usually in the middle upper part of the tail, are
known as stingrays, a word corrupted to stingaree.
Several dozen species of stingrays are known to science. These
creatures occur in all warm seas, as well as in many of the tropical rivers,
some fresh-water stingrays in South America occurring even more than
a thousand miles above the river mouth. Wherever stingrays occur —
in the seas, bays, or in rivers — they are to be found hiding on the
bottom in mud or sand. If disturbed, they swim with an undulating
motion, usually close to the bottom, and stir up a cloud of mud, then
come to rest on the bottom, the muddy cloud gradually settling
around the ray. This "mud cloud" and the camouflaged coloration
of the fish itself serve a definite purpose in concealing it. While thus
partly buried in the sand or mud bottom the stingray is in perfect
readiness to drive its sting into any unsuspecting victim that may
step on it. The weight of a person stepping on the disk-shaped part
of the body anchors the stingray, giving it the needed leverage to
whip its tail upward with uncanny precision and drive the already
erected spine or sting into its target. The sting on the powerful tail
of even a small ray only a foot across in size can pass through a
person's foot or into a leg bone.
ICHTHYOLOGY OF VENEZUELA — SCHULTZ 23
During 1942 my assistant, Rafael Navarro, and I were collecting
fishes in a swamp north of Sinamaica, Maracaibo Basin. We had
walked nearly half a mile across this shallow muddy mire, pushing a
small boat (cayuca) in front of us. Along the way we noticed many
stingrays measuring up to a foot across their disks. The water was a
few inches to a foot deep, and our feet sank as far into the soft muddy
bottom. We made a fair collection of the various kinds of fishes
present and started back. I urged Navarro not to pick up his feet
in this mud but to push them forward at the surface to avoid stepping
on a stringray.
Suddenly I heard him cry out in agony. A stingaree had driven its
spine into his anlde, but fortunately the spine did not break off.
When we reached shore I cleaned the wound, swabbed it out with
iodine, and bandaged it. At camp that night I found the wound
was deep, to the bone, but the flesh showed little swelling. I washed
it and put on a larger bandage saturated with 1:1000 metaphen.
After a week of this treatment the lesion was completely healed.
Since aU stingarees hide, partly bmied in the mud or sand of the
bottom, they are always a potential danger to all who wade over such
bottoms in tropical seas or in certain tropical rivers. Since the chief
hazard is caused by stepping on one of these fishes it is almost com-
pletely eliminated by pushing one's feet along the bottom in the upper
layer of mud or sand. Another method of avoiding the danger would
be to carry a pole and probe the bottom as one walks forward. The
moment something touches the ray it wiggles off.

The following counts were made: Number of oblique rows of teeth
from middle of jaw to outer edge, upper jaw 15, lower jaw 15; about
45 small spines along middle of back behind eyes and on middorsal
side of tail.
Remarks. — This new species appears to be the Atlantic representa-
tive of Urotrygon asterias (Jordan and Gilbert) because it has in com-
mon with that species a characteristic and definite single row of en-
larged spines along the middorsal line of the back and tail. Urotrygon
mundus differs from asterias and venezuelae by not having the enlarged
spines in a definite continuous row along the midline of the back;
instead they are irregularly placed. Measurements made on the types
of U. asterias are recorded along with those for U. venezuelae in table 1.
It may be distinguished from asterias and from other American rep-
resentatives of the genus Urotrygon by means of the key printed by
Beebe and Tee Van (Zoologica, vol. 26, pt. 3, p. 264, 1941):

Genus POTAMOTRYGON Garman
Potamotrygon Garman, Proc. Boston Soc. Nat. Hist., vol. 19, p. 210, 1877. (Geno-
type, Pastinaca humboldtii Roulin designated by Eigenmann, The fresh-
water fishes of British Guiana, p. 116, 1912.)
Pastinaca Swainson (Natural history of fishes, amphibians . . .,
vol. 1, p. 172, 1838), is not a synonym of the genus Potamotrygon
Garman, as Swainson says: "Pastinaca Antiq. differs from Try g on
only in having the tail entirely naked: the common sting ray of the
Mediterranean is the type of this genus, to which we prefer retaining
the name by which it was known to the ancients." Pastinacae
Nardo, Giorn. Fisica de Pa via, vol. 1, p. 11, 1827, with genotype Raja
pastinaca Linnaeus, is an older name according to Jordan (Genera
of fishes, pt. 1, p. 121, 1917).
I have had for examination, in addition to the series listed from the
Maracaibo Basin, two specimens from the Orinoco system, two from
the Kio Ampiyacu of the Peruvian Amazon, and one from the Rio
Magdalena. On these I have based my key. Because of the vari-
ability in body proportions I considered it advisable not to use the
measurements. The coloration is so strikingly different for the
specimens from the three drainage basins that I am able to dis-
tinguish the three species at a glance. The presence or absence of
white blotches or black spots on the dorsal surface was so variable
for the large series of specimens from the Maracaibo Basin that I
cast serious doubt on those characters as of value in distinguishing
the species referable to the genus Potamotrygon.
For detailed measurements made on specimens of Potamotrygon,
see table 2.

This species of stingray occurs abundantly in the rivers, ponds,
canos, and lakes of the Maracaibo Basin on sandy to muddy bottoms,
where it partially conceals itself by burying itself in the bottom. In
this position it is a dangerous fish because when it is stepped on it can
drive its poisonous sting with great force into a person's foot or leg.
The Venezuelans greatly fear it because its sting not only produces
excruciating pain but may cause death. The largest stingray that I
saw was a female in the Rio Machango. It measured a little over a
foot across the disk.

PROCEEDINGS OF THE NATIONAL MUSEUM
This stingray does not appear to have been described very fully in
the past, and for that reason the following descriptive comments are
recorded, along with measurements in table 2.
The disk is a httle longer than wide, evenly rounded; the tip of the
snout has a little soft knoblike projection beyond the outline of the
disk; the tail is longer than length of the disk, although the end of the
tail is almost invariably missing except on the embryos, and therefore
total length means very little; spu-acles about size of eye and located
just behind eyes; the space between the spiracles greater than inter-
FlGURE 3.

ICHTHYOLOGY OF VENEZUELA — SCHULTZ 31
orbital space, the latter about twice the length of the snout, interorbital
space nearly flat; the mouth is a little closer to tip of snout than to
front of the eye ; inside the mouth there are always five blunt papillae
on the lower jaw behind the teeth, the papilla in the midline a little
in advance of the others, all four of which are in a straight line or
nearly so; behind the teeth of upper jaw is a broad membrane whose
inner margin has about 25 lappets; the nasal flap is free with a truncate
fringed margin; the teeth are diamond-shaped with a posteriorly pro-
jecting blunt median tip, each side of which is a slight concavity; the
greatest width of the toothed area of the upper jaw about two-thirds
that of lower jaw; pelvic fins when spread with outer margins truncate
or a little rounded, outer tips rounded; the claspers are variously
developed at difl^erent sizes, the smallest specimen with fully developed
claspers measures 210 mm. from tip of snout to end of sting and the
diameter of the clasper was about 10 mm., its length 43 mm.; the
spines along middorsal line of back in front of base of sting are absent
on the embryos and postembryos but begin to appear at a length of
about 200 mm. (from snout tip to end of sting) and the greatest num-
ber of such spines coimted was 23; the sting when fully developed is
about as long as the snout, fully barbed along its sides and with a
lengthwise groove near base of the barbs that no doubt contains the
poison glands and venom; the upper surfaces of the body are covered
with minute scales and then in addition some specimens have numer-
ous to few scattered stellate tubercles; under side of body naked.
Color. — Dorsal surface plain dark bro\\Ti or dark brown with
numerous scattered smaU black spots, and occasionally the dorsal
surface has light blotches; ventral surface plain pale except rayed
parts of pectorals, which are grayish to brownish, more intense around
the margins, and sometimes a few black spots occur near margins of
the disk; outer corners of upper lip sometimes darkish; under side of
tail blotched or mottled; tail of young and postembryos somewhat
faintly barred. When alive the under sides were purplish to pinkish.
Frequently when a female ray was placed in the collecting can it
would give birth to one to four embryos.
Family MYLIOBATIDAE : Eagle and Cow-nosed Rays
This family may be recognized by the pectoral fins not being con-
tinuous to the end of the snout. They end on the side of the head
behind the eyes, reappearing again in the front of the snout as one or
two fleshy protuberances. The pectoral fins are pointed distally and
the tail is long and whiplike with a spine basally.

This giant ray may be recognized by the presence of a pair of fleshy
hornlike projections from the front of the snout that turn inward.
The eyes occur laterally near the outer base of each of the two fleshy
cephalic projections.
Suborder Narcobatoidea
Family TORPEDINIDAE: Electric Rays; Tembladores
This family of rays has a disk-shaped body that tapers posteriorly
to a blunt thickish caudal fin; there are two small dorsal fins but no
"sting" or spine on the tail. The disk-shaped part of the body lateral
to and behind the eye is supphed with an electric gland capable of
giving a powerful electric shock when it is touched.

Family ENGRAULIDAE: Anchovies; Anchoas
The recent excellent revision of this family by Dr. S. F. Hildebrand
(Bull. Bingham Oceanogr. Coll., vol. 8, art. 2, 1943) was indispensable
in this study of the anchovies of Venezuela. During the several years
that Dr. Hildebrand was preparing this revision he assembled in the
U. S. National Museum one of the most complete collections of Amer-
ican anchovies to be found in any museum, including numerous types,
cotypes, and paratypes. It gave me considerable pleasure to be
able to add several thousand more specimens to this collection, among
which were sLx known species and four undescribed ones, all collected
by me in Venezuela during 1942.
I have followed Dr. Hildebrand 's treatment of the Engraulidae to
a large extent, deviating, however, in the anal-fin formula. Since
the first three anal rays are unbranched I have represented them by
lower-case Roman numbers followed by Arabic numerals for the
branched rays, thus: iii,24. The first pectoral rays consist of two
simple ones, followed by branched rays, the first pectoral ray being
of paper thinness and lying close to the second. The dorsal consists
of a minute simple ray, then two larger ones, followed by branched
rays.
The following key to the genera of Engraulidae reported from
Venezuela is somewhat modified from Dr. Hildebrand's in order to
call attention to the greatly coiled condition of the intestine in Ceten-
graulis. Engraulis is omitted, since it has not as yet been found in
Venezuela.

gill membranes never broadly united across the isthmus, at most only a
narrow delicate membrane anteriorly.

ICHTHYOLOGY OF VENEZUELA — SCHULTZ 41
Body compressed, deep, greatest depth about 3.5 to 4.2, and head
about 3.3 to 3.5, both in standard length; depth of head at joint of
mandible much less than postorbital length of head; head longer than
greatest depth of body; snout bluntly pointed, projecting more than
half its length beyond mandible, shorter than eye, scarcely longer
than pupil, contained 5% to 5% in head; eye 3.4 to 4.2 in head; maxillary
ending in a triangular point, extending to or a little past joint of
mandible, contained about 1.3 or 1.4 in head; mandible pointed, not
curved upward at tip, reaching a vertical line through rear edge of
posterior nostril when mouth is closed; teeth most minute but very
numerous along edges of both jaws, often obsolete in adults; cheek
6.6 to 7.1 and postorbital length of head 5.2 to 5.6 in standard length;
gill rakers very long and slender and very numerous, increasing in
number with increase in length or age; depressed length of dorsal
fin 1.5 to 2 in head; the first branched rays of dorsal fin reaching a little
past tips of last rays when the fin is depressed; distal margin of dorsal
fin truncate or a little concave; caudal fin deeply forked; distal margin
of anal fin a little concave, first anal rays longest; first upper ray of
pectoral fin longest, tips of pectoral fins reaching past the insertion
of pelvics, sometimes to opposite nearly halfway toward tips of pelvics
in young specimens; pelvic fins reaching halfway to anal origin in
young but scarcely halfway to anus in adults; dorsal fin origin equi-
distant between midcaudal fin base and front half of eye; origin of
anal fin under middle of base of dorsal fin; axillary scale of pectoral
extending out about halfway to tip of pectoral fin; intestine with one
main loop.
Coloration. — In alcohol the adults are straw-colored dorsally, silvery
on sides, with a dark brownish streak along middorsal line of back;
inside of gill cavity blackish ventrally opposite region of maxillary;
all fins translucent-whitish except caudal fin, which is dusky with the
black pigment cells more intense on distal part of rays; peritoneum
silvery but intestine blackish. In the young a silvery lateral band
about as wide as eye anteriorly becomes narrower posteriorly. The
most characteristic mark is a small black speck at lower base of
caudal fin, with a small cross of X-shaped lines of black pigment
more or less embedded; base of anal fin with black pigment spots;
tip of snout blackish; middle basal part of each lobe of caudal fin
more intensely pigmented than remainder of caudal fin; otherwise
coloration is similar to that in adult specimens.
Eemarks. — This new species would, with some exceptions, trace
down through Dr. Hildebrand's key (1943, p. 21) to A. rastralis, but
it differs from that Pacific species in having 39 to 41 (usually 40)
vertebrae instead of 41 or 42. From A. clupeoides it may be separated
by the key on page 38. Named nigra in reference to the black pig-
mentation on inside of the gill cavity.

The specimen from Amuay Bay recorded by Dr. Hildebrand does
not seem to be in the national collections. Both of the first gill arches
were destroyed, according to his original data, and thus the specimen
measuring 63 mm. in total length was referred to A. tricolor with
much doubt. I have not seen any specimens of this species from
Venezuela, and for identification the number of gill rakers must be
known.

One specimen, 35 mm., Laguna de Tacarigua, Estado de Miranda, F. F. Bond,

I have carefully examined the two collections from the Gulf of
Venezuela referred by Dr. Hildebrand to Anchoa januaria, U.S.N.M.
Nos. 127675 and 127676, from Amuay and Salinas Bays, respectively.
I found that the gill raker count of U.S.N.M. No. 127675 in one
specimen was 18+24 and that the other two specimens had their
first arches destroyed, which explains the fact that they were not
counted by Dr. Hildebrand, who has been most cooperative in letting
me use his original data. One specimen in U.S.N.M. No. 127676 has
17+26 gill rakers, but the others have 12 on the upper arch and
numerous small, sharp-pointed teeth in both jaws and a short maxillary
with rounded posterior end. I am therefore referring them to
Anchoviella hlackhurni. Thus, the range of A. januaria must again
be restricted to Brazil.
The following counts were made on specimens from Venezuela.
Anal rays iii,18 in 4, iii,19 in 9, iii,20 in 6, and iii,21 in 9 specimens;
pectoral rays i,ll in 2, i,12 in 4, and i, 13 in 4; vertebrae 39 in 1 and
40 in 11 specimens; on 3 specimens the gill rakers were as follows:
18+1+27; 18+1+26; 19 + 1+26; 17 + 1+25; 18+1+23; and
18+1+25. The dorsal fin had ii,13 rays in 2 specimens counted.

ICHTHYOLOGY OF VENEZUELA — SCHULTZ 47
origin of anal fin under a vertical line through middle of length of dorsal
fin base; axillary scale of pectoral extending out about halfway to tip
of pectoral fin; upper posterior margin of operculum truncate or nearly
so, the lower posterior corner angular with short concave edge, figure
6, h, length of base of anal fin 3.2 in standard length.
Coloration. — In alcohol, the back is straw colored with considerable
dark pigmentation; these pigment cells extend over middle of front
of snout but sparsely; the lower two-thirds of sides of body are silvery;
dark pigment cells are numerous basally on dorsal fin becoming fewer
distally and wholly lacking on outer third of fin; outer margins of
caudal fin darkish, but middle of caudal fin and its distal parts non-
pigmented; anal, pectoral, and pelvic fins nonpigmented.
Remarks. — This new species would trace down through Dr.
Hildebrand's key to the species of Anchoa on pp. 29-30 of his revision
of the Engraulidae to his section "C" for Anchoa spinifer. However,
A. argenteus differs from spinifer in having fewer anal rays, iii,29
instead of iii,33 to iii,38, and the posterior margin of caudal and tip
of dorsal fin are not blackish as in spinifer. From the local Venezuelan
species of Anchoa it may be separated by the key on page 42.
Named argenteus in reference to the briUiant silvery lower sides.

less than half its length beyond tip of mandible, shorter than eye, and
contained 5.5 to 6 times in head; eye 3 to 4.2 times in head; maxillary
slender, not notably pointed, extending to or a little past joint of
mandible, 1.3 to 1.4 in head; mandible pointed, curved slightly up-
ward at tip, reachmg a little past a vertical line through front of

and rear margin of pupil; origin of anal fin under bases of fifth to
seventh branched rays of dorsal fin or a little behind middle of base
of dorsal fin; axillary scale of pectoral about three-fourths length of
pectoral fin.
Color. — The color of preserved specimens in alcohol is grayish above
with a dark streak along middle of back; margin of caudal fin with a
narrow blackish band ; interradial membranes of caudal fin lobes with
black pigment, especially intense between the third and fourth from
middle on lower lobe and fourth and fifth from middle on upper lobe,
the middle rays between almost unpigmented; middle of snout with
black pigment; upper edge of maxillaries anteriorly with black pig-
ment; inner side or opercle heavily pigmented; peritoneum silvery;
silvery lateral band present and as wide as snout and eye over region
of anal fin origin.
Remarks. — This new species is so distinct that it does not resemble
any form known at present. It is as slender as L. olidus but has 41
(rarely 42) vertebrae instead of 46 to 48. L. grossidens has 43 or 44
(rarely 45) vertebrae and a much greater depth of body than L.
limnichthys. In Hildebrand's review of the American anchovies
(1943, pp. 141-142), it would trace down to a new section in his key,
ddd on p. 141. It may be distinguished from other Venezuelan
anchovies by the key on page 50.
The smallest female observed with fully mature eggs, apparently

Order OSTARIOPHYSOIDEA
Suborder Characinoidea
Family CHARACINIDAE
The characinid fishes were reported upon by me in a previous paper
entitled "The Fishes of the Family Characinidae from Venezuela, with
Descriptions of Seventeen New Forms," published in the Proceedings
of the United States National Museum, volume 95, pp. 235-367,
figs. 30-56, September 6, 1944. That study was based on the speci-
mens that I collected in Venezuela during 1942 as well as on other
specimens in the United States National Museum collections and on
the literature. In that report were recorded from Venezuela 58
genera and 117 species and subspecies, and 29 of these species were
from the Maracaibo Basin.
I take this opportunity to correct some of the more important
errors that have been observed in my report on this group of fishes.
On page 258 I introduced the new subfamOy name Ctenolucinae,
but Dr. C. L. Hubbs has called to my attention that in Copeia, 1939,
No. 3, p. 168, he had introduced the subfamily name Hepsetinae for a
related characinid occurring in Africa. It is by no means certain that
the African group is as closely related as the external features seem to
indicate, but pending further investigations I shall recognize the
subfamily Hepsetinae.
In table 7, p. 263, for asper the number of scales above lateral line
should be one count each for 7 and 8 instead of 11 under 7 as given.
56 PROCEEDINGS OF THE NATIONAL MUSEUM vol.99
On page 264, last two lines of large type 7 or 8 should be transposed
with 8 or 9.
I overlooked three species described as new by Valenciennes in
Cuvier and Valenciennes, Histoire Naturelle de Poissons, volume 19,
1846, until it was too late to enter them in my report. The following
should be referred to the synonymy of Hoplias malaharicus (Bloch):
Macrodon tareira, p. 508, from Lago de Maracaibo; Macrodon teres,
p. 521, from Lago de Maracaibo; and Macrodon guavina, p. 527,
from Laguna de Tacarigua, Valley of the Rio Aragua.
Enrico Tortonese (1942, p. 75, pi. 2, fig. 3) reports Hemihrycon
dariensis Meek and Hildebrand from Rio del Paso Real, Puerto
Cabello, Venezuela. Since his description and figure agree fairly
well with specimens from the Rio Tuy and Rio Gudrico systems, I
refer the identification made by Tortonese to Hemihrycon dentatus
metae Myers, keyed out in my characinid paper on p. 363.
Suborder Gymnotoidea: Feces Cuchillo
Body elongate, usually compressed, eellike; with or without scales;
head naked; dorsal fin lacking or represented by a fleshy filament
mostly attached along back posteriorly; pelvics absent; anal fin very
long; pectoral fins short, rounded; caudal fin absent or very small,
the tan tapering to a point in species lacldng the caudal fin; mouth
with or without teeth; premaxillary and maxillaries forming upper
jaws; anus always in front of middle of pectorals, usually under middle
of head; shoulder girdle suspended from skull; symplectic bone present;
air bladder in two parts connected by a tube; stomach with bhnd sac
and pyloric caeca (after Ellis) .
Since publishing my description of Hypopomus beebei in Zoologica,
1944, and placing it in the family Gymnotidae, I have concluded that
it may be advantageous to break this group up into at least three
families as recognized in the following key:
KEY TO THE GENERA REPORTED FROM VENEZUELA »
la. Lower jaw not prolonged or longer than upper jaw; a large frontal and
parietal fontanel along middorsal line of head; head not depressed; teeth if
present villiform or minute; electric organs absent (family Sternarchidae).
2a. Caudal fin absent; the tail behind anal fin slender and tapering to a point;
dorsal filament absent.
3o. Snout not tubular, but short or moderately elongate.
4a. Orbital margin free; both jaws with villiform teeth.

theses, are recorded below, respectively. Total length in mm. 505
(187).
Distance from tip of snout to rear end of anal fin in mm. 455 (160).
Length of anal fin base 81.7 (86.3); length of head 16.5 (16.9); snout
5.28 (5.75); eye 0.92 (1.06); interorbital space 2.75 (3.81); postorbital
length of head 10.0 (10.6); distance from snout to anus 10.3 (11.9);
snout to anal origin 16.8 (18.1); snout to occiput 12.9 (13.5); snout to
pectoral insertion 16.1 (10.9); length of longest pectoral ray 6.26
(6.88); longest anal ray 5.72 (6.56); greatest depth of body 13.1 (12.8);
depth of head through eyes 5.82 (5.94) ; distance from anterior nostril
to posterior nostril 1.87 (1.88); eye to posterior nostril 2,53 (2.56);
width of gill opening 4.28 (5.38); tip of snout to rictus 3.41 (3.12);
tip of snout to rear of maxillary 3.96 (3.44) ; length of tail beyond end
of anal fin 11.2 (16.4).
The following counts were made, respectively: Anal rays 298 (282);
pectoral rays iii,13-iii,14 (iii,13-iii,13). There appear to be about
20 to 25 scales between the lateral line and midline of the back.
ICHTHYOLOGY OF VENEZUELA — SCHULTZ 61
Body compressed, tail rounded beyond end of anal fin; snout elong-
ate; rear margin of eye in front of middle of length of head, a distance
equal to the space between eye and posterior nostril; dorsal profile of
head usually a httle concave, sometimes nearly straight in the young;
pectoral fin equal to distance from rear of eye to snout tip ; margin of
eye free ; gill opening extending some distance above and below pectoral
fin base; anal origin under rear of base of pectoral fin; anus under
middle of length of head; lateral line straight, complete; scales on
upper sides of body and on tail a Httle enlarged; interorbital space
convex equal to distance from tip of snout to rear nostril; length of
head much longer than greatest depth; head about 5K to 6 times in
distance to end of anal fin; tail extends beyond anal fin a distance
about equal to or a little greater than length of head.
Color. — Body uniformly dark brownish everywhere ; middle of sides
posteriorly with a narrow pale streak, lemon yellowish in living fish;
operculum with slight intensification of the pigment; all anal and aU
pectoral rays darkish, the interradial membranes pale.
Remarks. — This new species is most closely related to Sternopygus
dariensis Meek and Hildebrand from Panama. It may be dis-
tinguished from it by having the pale streak along midaxis of body and
tail posteriorly and by the key on page 59. From S. macrurus the
new species differs in having the head with a concave dorsal profile,
and in addition, the interorbital space is more convex and narrower
in S. pejeraton.
Named pejeraton, after the common name of this fish, peje rat6n, as
given to me many times in the Maracaibo Basin, in reference, no
doubt, to its rathke tail.

hsted above: 179; 180; 182; 184; 185; 187; 187; 190; 194; 198; 199; 201
and 205.
This species, when taken from the water, was silvery in coloration
and more or less translucent.
As a result of my examination of various specimens of Eigenmannia
centering around the species currently recognized as virescens, I am
forced to conclude that this species should be broken up into one or
more subspecies. One should especially note that in British Guiana
two species are undoubtedly passing under E. virescens. Specimens
from the Botanic Garden (U.S.N.M. No. 66296) and others have 185
to 198 anal rays. Those from Wismar (U.S.N.M. No. 66298) have
208 to 224 anal rays and the anal fin has a dark band distally more
ntense anteriorly on these alcoholic specimens. I have not yet been
able to work out the valid names for these two species. Undoubtedly
the Panamanian form of virescens should be described as a new sub-
species on the basis of fewer anal rays (165), a larger eye, and longer
pectoral fin, but I hesitate to take this step as our only specimen is
without a tail.

anal-fin base; the dorsal profile of the head is straight or with a very-
slight concavity; the snout is somewhat pointed and rounded; the
rear margin of the eye is at about the midlength of the head or a httle
in front of it; the eye is contained 2% to 3 K in the snout and 1.5 to 1.8
in the interorbital space; the anus is under rear of eye; origin of anal
fin under rear of base of pectoral fin; the gill opening extends above
and below base of pectoral fin; upper and lower jaws with patches of
vilHform teeth; the lower jaw is a little shorter than upper, so that
the snout projects a little; the mouth is small, so that the rictus or
corner of mouth is just a trifle behind a vertical line through anterior
nostril; tip of snout to rear of maxillary 2 in snout; distance between
anterior and posterior nostrils 1.5 times in distance from eye to
posterior nostril; the interorbital space is convex, and its width is
equal to the distance from the tip of snout to posterior nostril; the
lateral line is straight; body and tail covered \Aath scales, head naked;
the scales along sides of body largest; about 13 or 14 rows of scales
between lateral line and middorsal line; the pectoral fin length is
equal to the distance from center of eye to rear of head; fontanel
present along middorsal line of head. Apparently both specimens
are males with short anal papillae and the testes are fully developed.
Color. — Live examples of this species were silvery on sides and a
httle darker dorsally. In alcohol it is plain pale in color on sides and
pale brownish dorsally; a dark brown streak continues on dorsal sur-
face of tail to its tip, contrasting sharply \vith the whitish sides and
whitish ventrally; pectoral and anal fins white; operculum with a
dark blotch; peritoneum pale.
Remarks. — This new species of gymnotid eel would trace do^vn
through the "Key to the Species of Genus Eigenmannia" by Eigen-
mann and Allen (1942, p. 315) to their new species E. conirostris on
the basis of 239 to 259 anal rays; all other species of Eigenmannia,
such as virescens, troscheli, and macrops, have fewer than 225 anal
rays. In addition, macrops has the caudal filament equal to "half
the total length without the head," while in goajira the caudal filament
is contained nearly 3 times in the anal-fin base; virescens has a black
streak along lateral fine, another along base of anal fin, both lacking
in goajira; troscheli has a very bluntly rounded short snout contained
about 3.75 to 4 in the head instead of 2.6 to 3 in the head of goajira.
E. conirostris and the new species are closely related but differ in the
position of the eye; in conirostris the rear margin of the eye is about an
eye diameter closer to tip of snout than rear of head instead of equal
distance as in goajira; in addition, goajira appears to have a larger
number of anal rays, 255 and 263, than conirostris with 239 to 259.
Named goajira in reference to the district inhabited by the Goajira
Indians, where this fish was collected.

Genus HYPOPOMUS Gill
Hypopomus Gill, Proc. Acad. Nat. Sci. Philadelphia, 1864, p. 152. (Genotype,
Rhamphichthys mulleri Kaup.)
After examining the material in the national collections, along with
four specimens collected by Dr. William Beebe at Caripito, Venezuela,
and comparing these with figures and descriptions of the already
described species, I have considerable doubt as to the identifications
made by Ellis in his review of the family Gymnotidae and by Eigen-
mann in his work on British Guiana fishes. (The two accounts are
nearly identical.) The specimens from Caripito have a very bluntly
rounded snout and shorter head, and the pore above the posterior
nostril differs in position when compared with forms from other
localities. Unfortunately, Kaup did not show the position of that
pore in reference to the posterior nostril, but his measurements of
and his figure of artedi indicate that this species has a pointed snout
with the rear margin of the eye behind the middle of the length from
snout to occiput, while in other forms it is equidistant between, as
shown in figures and in the specimens before me. Steindachner's
figure of brevirostris fortunately shows the position of the pores in
reference to the posterior nostril, and these are the same as in the
specimens that I am referring to occidentalis Regan from Panama and
the Maracaibo Basin, but the species must be dift'erent since brevirostris
has 259 or 260 anal rays instead of fewer than 240 in the other species.
Because of the above differences it appears probable that the speci-
mens from Caripito represent a distinct species, whereas those from
the Maracaibo Basin are so close to those from Panama that I
identify them as the same form. Measurements made on available
specimens are recorded in table 9.

I wish to point out an error in the figure of this species as published
(Schultz, 1944g, pi. 1, fig. 4). On the head occurs a small black spot
that might be mistaken for the e5'^e but that does not occur on the
fish or on the original photograph but mysteriously appeared when
printed. The text figure fortunately shows the eye in its proper
position as does the plate mentioned above. In the latter the eye is
the whitish area near the front of the snout.
The followmg description is of the holotype, U.S.N.M. No. 102753,
and three paratypes in the collection of the New York Zoological
Society. Measurements, along with those for other species, are
presented in table 9.
Body compressed, tail slightly compressed and tapering to a point;
head bluntly rounded; snout short, about equal to interorbital space,
contained about 4.2 times in head; jaws without teeth; length of pec-
toral fin 2 in head; lateral line straight, the 3 rows of scales below and
about 4 rows above enlarged ; scales along back and ventrally on body
much smaller in size; head a trifle longer than greatest depth; origin
of anal fin about opposite tips of pectorals; anal papilla present, its
base under middle of opercle or a vertical Ime through occiput passes
through base of anal papilla; lower jaw very slightly shorter than up-
per; mouth terminal, small; cephalic canals and pores prominent;
mucus pores numerous on head; gill openmg extending a little above

pectoral insertion 16.7 (16.7; 18.8); snout to anal origin 15.3 (14.8;
11.7); snout to anterior end of groove between dorsal filament and
back or rear base of dorsal filament 66.7 (69.0; 65.7) ; length of longest
pectoral fin ray 7.88 (8.90; 8.85); longest anal ray 5.91 (6.68; 7.19);
longest caudal fin ray 3.24 (3.46; 3.47).
The following counts were made, respectively: Anal rays 187
(197; 181); pectoral rays ii,16-ii,16 (ii,15-ii,16; ii,16-ii,16); number
of pores to end of lateral line 100 (101; 96); 3 scales between base of
dorsal filament and lateral line.
Body compressed, caudal region compressed; caudal fin about
three-fourths length of snout; caudal peduncle about one-half length
of head; pectoral fin length a little over one-half length of head;
snout elongate, somewhat pointed, the dorsal profile of head a little
concave or straight; greatest depth of body a little behind tips of
pectorals; lower edge of gill opening opposite middle of pectoral base
or a little below the middle; eye small without a free membrane and
contained from 6 to 11 times in the snout; rictus under posterior
nostril; anterior nostril tubular; posterior nostril a little closer to
eye than tip of snout; anus under a vertical about 2 diameters behind
rear of eye; rear edge of base of dorsal filament about equal distance
between tip of caudal fin and rear of head or base of pectoral fin;
ICHTHYOLOGY OF VENEZUELA — SCHULTZ 71
at about half the distance from tip of snout to base of dorsal filament
there are 13 or 14 scales between lateral line and middorsal line; the
third or fourth branched rays of pectorals longest; anal rays near mid-
dle of that fin longest; lateral line straight, complete, the scales along
lateral line and midsides largest, gradually becoming smaller dorsally
and ventrally; caudal fin minutely scaled for three-fourths the way
out, the last third naked; interorbital sharply convex, about equal
to distance between anterior and posterior nostrils and about 3K in
the head; origin of anal under gill opening; tip of lower jaw with a
groove separated by a frenum at each side of tip from groove along
sides of lower jaw; mouth terminal, lower jaw fitting up between the
maxillaries; a small patch of villiform teeth on each side near front
of upper jaw; two rows of a few conical teeth at sides of lower jaw;
apparently no teeth near symphysis of lower jaw; a long fontanel
along middorsal line of head.
Color. — In alcohol the ground color is mottled dark brown or
blackish at all ages, but the white color markings are greatly variable
with increase in length. A specimen 132 mm. in total length has a
cream-white band that encircles the body in the last one-fourth of
the anal fin, but the white color does not quite reach to end of anal
as the last few rays are blackish; the caudal peduncle is blackish
except posteriorly where a second narrow wliite band encircles it
just in front of base of caudal fin; caudal fin and anal fin blackish
except posteriorly; tip of chin pale or white; a white band from snout
tip along middorsal line to top of head thence represented by a few
pale blotches for a short distance along the back; pectorals blackish.
A specimen 250 mm. in total length has the white streak along
top of head ending at occiput, and the wide white band near rear of
anal is broken up by numerous dark brown blotches, but there is no
dark blotch on the anal fin; otherwise coloration as in the specimen
132 mm. long.
In the holotype, 363 mm. long, the pale band at rear of anal is
almost lacking, as the sides of the body in that region are blackish,
along the midline of back are a few white blotches and part of anal
fin is still white; the white band just in front of caudal fin is reduced
in width. In the largest specimens the white band at rear of anal
may be completely lacking but the narrow white streak at base of
caudal fin does not completely disappear.
The peritoneum is pale.
Remarks. — This new species is close to leptorhynchus in shape of
head and snout but dift'ers from it in having the eye considerably
in front of middle of length of head and also in several other respects,
as indicated in the key on page 68. In coloration this new species
differs from all others referred to the genus Apteronotus except A.
72 PROCEEDINGS OF THE NATIONAL MUSEUM vol.99
alhifrons, which has the two white bands encircHng the body; it
differs in its elongate snout, blunt and rounded in alhifrons, as indi-
cated in the key. Apteronotus anas Eigenmann and Allen has the
eye far back, considerably behind middle of length of head.
Named cuchillo, the common name of this type of fish in Venezuela,
probably referring to its knifelilve shape.

species referred to the genus Stemarchogiton by its fewer number of
74 PROCEEDINGS OF THE NATIONAL MUSEUM vol.99
anal rays, 137 to 146, instead of more than 190 as well as in its colora-
tion. In addition, there are two irregular rows of teeth on each side
of the lower jaw instead of a single row in the other species. This
tooth character may be of significance generically. The following key
may be used to identify the species referred to Stemarchogiton:
la. Anal rays about 197 or 200; sides of lower jaw with a single row of teeth; no
pale streak along middorsal line.
2a. Head about 12 in length; eye about 3J4 in the head.
S. nattereri (Steindachner)
26. Head about 9 in length, eye 7 in snout; posterior half of pectoral rays dark
and distal part of anal rays blackish.S. porcinum Eigenmann and Allen
lb. Anal rays 137 to 146; 2 rows of short conical teeth on sides of lower jaw;
middorsal hue of back with pale streak anteriorly; pale blotch on chin;
head 8 to 9 in total length; eye 3 to 3 >4 in snout; fins all pale in color.
S. cuchillejo, new species
Some of the females have pale amber-colored eggs in their ovaries
and appear to be nearly ready to spawn.
Named cuchillejo for the popular name of this small knife-shaped
fish.

Suborder Nematognathoidea: Catfishes; Bagres
My first report on the collections of fishes that I made during 1942
in Venezuela covered this group. The publication is entitled ''The
Catfishes of Venezuela, with Descriptions of Thirty-eight New Forms,"
and it appeared in the Proceedings of the United States National
Museum, volume 94, pp. 173-338, figs. 1-5, pis. 1-14, February 11,
1944. This report contains an itinerary of my travels and a map
showing the localities where specimens were collected, along with a
Ust of collecting stations. For all of Venezuela 127 species and sub-
species in 63 genera and 12 families are listed.
Since the publication of this report two papers have appeared under
my authorship on the catfishes of Venezuela: "Two New Species of
Fishes (Gymnotidae, Loricariidae) from Caripito, Venezuela," Zoo-
logica, New York, vol. 29, pt. 1, pp. 39-44, fig. 1, 2, pi. 1, May 10,
76 PROCEEDINGS OF THE NATIONAL MUSEUM vol.99
1944, and "Pygidium monodolfi, A New Catfish from Venezuela,"
Journ. Washington Acad. Sci., vol. 35, No. 1, pp. 29-31, fig. 1,
January 15, 1945 (near Caracas). In addition I have published two
other recent papers on catfishes from Colombia: "A New Loricariid
Catfish from the Kio Truando, Colombia," Copeia, 1944 No. 3, pp.
155-156, September 30, and "A New Genus and Species of Pimelodid
Catfish from Colombia," Joum. Washington Acad. Sci., vol. 34,
No. 3, pp. 93-95, fig. 1, March 15, 1944.
A few errors in my report on the catfishes of Venezuela have been
observed, and I take this opportunity to correct some of the more im-
portant ones. On page 182, 11a should read without, and on the next
page 36, next to last line should read 6 + H or 12 instead of 6 + 17.
The tenth line, third paragraph p. 335, should read 47.6, not 4.76.
Addenda to my report on the catfishes of Venezuela, 1944:
1. Hexanemathichthys rugispinis (Cuvier and Valenciennes). 1 specimen 275
mm., from mouth of Rfo San Juan, near Caripito, April 11, 1942, William Beebe.
2. Selenaspis herzhergii (Bloch). 1 specimen for each — C.N.H.M. Nos. 41990
and 41989, from Lago de Maracaibo, W. H. Osgood, 1911.
3. Pimelodus darias coprophagus Schultz. 1 specimen each, C.N.H.M. Nos.
41988, 42011, 42013, 42014, 42015, from Encontrados, W. H. Osgood, 1911.

6. Microglanis iheringi Gomes, Occ. Pap. Mus. Zool. Univ. Michigan, No. 494,
p. 9, pi. 1, 1946 (Rfo Turmero near Turmero, Aragua; Carabobo, Venezuela).
7. Perrunichthys. Recently a skin and head of a species in this genus was
found in the National collections collected by Prof. Orton probably at the junction
of the Napo and Maran6n Rivers of the upper Amazon. This head with skin
definitely represents a species distinct from P. perruno Schultz of the Maracaibo
Basin, but a better specimen should be obtained before describing and naming it.
8. Dupouyichthys sapito Schultz. Cecil Miles, of Colombia, wrote to me on
July 2, 1945, that a man collecting for him in the Magdalena system just brought
a specimen of this species %\ith 6 or 7 almost fully developed eggs adhering to the
pelvic fins and the preanal region. Mr. Miles is to be highly complimented on
the discovery of this remarkable habit of incubation of eggs for the genus, although
such a type of egg incubation is known for certain Asiatic catfishes. He published
on this in Caldasia, vol. 3, No. 15, p. 454, 1945.
9. Pygidium conradi Eigenmann. 9 specimens, 20 to 33 mm., from Guachaco
Cave, Rfo Caripe near Caripito, William Beebe, 1942.

18. Loricaria caracasensis (Bleeker), Described by Bleeker in his "Systema
Silurorum Revisum," Nederl Tijdschr. Dierk., vol. 1, p. 81, 1863, as Hemiloricaria
caracasensis Bleeker, from Caracas. It is the genotype of Hemiloricaria, a
monotypic genus.
Bleeker described this species as follows: "Velum labiale vix fimbriatum
postice latum, antice angustum. Dentes utraque maxilla conspicui. Cristae
occipitales vel nuchales dentatae nullae. Scuta trunco carina dentata. Regio
subthoracicoanalis scutata. Pinna dorsalis supra ventrales incipiens.
"Spec. typ. Hemiloricaria caracasensis Blkr. sp. nov in Mus. L. B. sub. nom.
Loricariae (Caracas) Conserv."
Not having any specimens from the Rio Guaire at Caracas, I am unable to
determine the species from Bleeker's description.
19. Loricaria eigenmanni Pellegrin, Bull. See. Zool. France, vol. 33, p. 125,
1908 (Sarare, Venezuela). This species was omitted.

Apure at San Fernando de Apture, F. F. Bond, February 16, 1938,
has a distinct black spot not observed in those of small size from
the Maracaibo Basin.
The large specimens from Lago de Maracaibo at the mouth of the
Rio Concha were apparently ready for spawning, as a light pressure
on the abdomen of the females caused pale yellowish eggs to flow
freely. The eggs probably adhere to the vegetation, as they appear
to possess fine adhesive threads and were very sticky when touched.

Description. — The description is based on the holotype and para-
types. Detailed measurements and counts are recorded in tables 10
and 11.
Head depressed, body compressed posteriorly, interorbital space
flat except on large males that have the top of head including interor-
bital space swollen and fleshy as shown in drasving (Myers, I. c, fig.
13) ; profile on females and young nearly straight; tip of lower jaw not
quite entering profile when mouth is closed; margin of eye not free;
teeth essentially as in stagnalis, but inner row of villiform band with
the teeth a little larger than others in this band; anterior nostrils
tubular, posterior nasal opening a slit above front of eye; cheek and
operculum scaled ; top of head scaled forward, a little in front of a line
between front of orbits; caudal fin scaled from one-half to four-fifths
the way out the rays, farther in the largest specimens; scales on
breast only a little smaller than on sides ; anus immediately in front of
anal origin; gill rakers about 3 -F 14 or 15; caudal fin with truncate
rear margin; middle rays of paired fins longest; usuaUy the sixth from
last ray of both dorsal and anal fins longest; pectoral fins usually reach
just to pelvic insertions or a little past but not to anus; pelvics reach
past anal origin; dorsal and anal fins when depressed reach to base of
caudal fin; dorsal origin equidistant between midcaudal fin base and
rear of head or a little behind head; anal origin in front of a vertical
line through dorsal origin and equidistant between midcaudal fin base
and middle of postorbital length of head to rear of head ; dorsal origin
about over base of second branched ray of anal fin; caudal peduncle
longer than deep in females or its length equal to its depth in large
males; caudal fin a little longer than eye and postorbital length of
head, anal fin of female with distal part of first or second to sixth anal
rays hardened and more or less fused into a glandlike pad.
Coloration. — In alcohol, pale tan with dark spots anteriorly on adult
males; a dark bar below eye more prominent on males; several very
faint small pale grayish spots on dorsal fin almost beyond visibility,
none can be seen on anal fin; caudal fin of adult males blackish.

Remarks. — This new subspecies may be distinguished from the other
members of the genus by means of the key on page 82. It has longer
pectoral fins than A. transilis transilis and more numerous scales on its
breast, whereas stagnalis has more numerous scales on its breast than
limnaeus.
Named limnaeus in reference to its habitat in ponds.

31.5 mm. in standard length. Drawn by Mrs. Aime M. Awl.
Remarks. — This new species may be distinguished from the other
two forms in the genus Austrofundulus by its wider upper lip, longer
pectoral fins, and crowded small scales on the breast. The key on
page 82 should enable the reader to identify this species from the
other two.
Named stagnalis in reference to its habit of living in stagnant ponds
or pools.

Dr. William Beebe kindly turned over to me a specimen 31.5 mm.
in standard length collected by him May 23, 1942, at Caripito, that
I tentatively identify with this species. Its caudal fin is more pointed
than usual in Rivulus.
The two specunens before me (U.S.N.M. No. 94308) from Pitch
Lake, Trinidad, have 6 branched dorsal rays, 11 branched anal rays,
90
PROCEEDINGS OF THE NATIONAL MUSEUM
and 13-13 pectoral rays. Regan's figure (I.e. pi. 21, fig. 2), probably
of the type of hariii, also shows 13 pectoral rays. Another important
character is the presence of only 6 branched dorsal rays in hartii.
Among the material of Rivulus available from Venezuela I fail to find
specimens that consistently agree with hartii, although collections
made in British Guiana and Brazil appear to agree fairly weU with
my material from Trinidad, the type locality of hartii.

92 PROCEEDINGS OF THE NATIONAL MUSEUM vol.99
holmiae Eigenmann (U.S.N.M. No. 66302) and finding no significant
differences, I decided to identify the specimens, at least tentatively,
with holmiae from British Guiana. This leaves a problem concerning
the distribution of holmiae to be studied when adequate series of this
form are collected in the intervening territory, but until material is
available it is preferable to leave the form on Margarita Island un-
named.
My chief basis for referring the specimens from the Isla de Mar-
garita to holmiae was the fin-ray and scale counts and coloration which
appear to agree in alcohol. It should be noted that in recording the
dorsal and anal rays I have included only the branched rays in table 12.
Dr. George S. Myers (1924, p. 96, and 1940, p. 171) has reported
Rivulus hartii from Margarita Island, Venezuela, based on U.S.N.M.
No. 94150, but I find that this specimen, as well as all the others from
that island that I have studied, has 8 branched dorsal rays instead of 6
as in hartii from Trinidad ; thus Ir efer Myers's records to the synonymy
of holmiae.

March 6.
Description. — The description is based on the holotype and para-
types listed above. Detailed measurements were made and these
are recorded in table 12 for the holotype and two paratypes.
The following counts were made, respectively, for the holotype and a
ICHTHYOLOGY OF VENEZUELA — SCHULTZ 93
paratype from Caracas: Dorsal rays ii, 7 (ii, 7); anal rays iii, 14 (ii, 15);
pectoral rays 16-15 (15-16); pelvic rays i, 6-i, 6 (i, 6-i, 6); scales from
upper edge of gill opening to midcaudal fin base 38 (39); scales from
dorsal origin to front of anal 9 (9) ; scales in front of dorsal fin to occiput
27 (28); number of scales in a zigzag row around caudal peduncle
15 (16); scales in a zigzag row across breast between lower edges of
base of pectoral fin 9 (10).

Figure 12. — Rivulus bondi, new species: Holotype (U.M.M.Z. No. 141914), 40.2 mm. in
standard length. Drawn by Mrs. Aime M. Awl.
Head depressed, but body compressed posteriorly, the greatest depth
about 5 and head 3.5 in standard length; margin of eye not free;
eye equal to snout and about 3K in the head; interorbital wider than
eye and about 2 in the head; rear margin of eye a trifle closer to rear
of head than tip of snout; origin of dorsal to midcaudal fin base con-
tained 2.9 times in distance from tip of snout to dorsal origin; origin
of anal fin a trifle closer to midcaudal fin base than middle of post-
orbital length of head; base of last anal ray under the base of third
from last ray of dorsal fin in posterior half of base of dorsal fin; pectoral
fins reaching more than halfway to anal origin but not to bases of
pelvics; pelvic fins reach just to anal origin; least depth of caudal
peduncle contained about 1.3 in length of peduncle from base of last
anal ray to midbase of caudal fin; caudal fin rounded; distal margin
of anal fin rather straight; pectorals, pelvics, and dorsal with rounded
margins; usuaUy fourth from last ray of dorsal and anal fins longest.
Coloration. — The color in alcohol of the holotype consists of a light
brownish background with rows of dark brown spots on sides, mostly
posteriorly, the row along midaxis most prominent and beginning
behind head, the other rows paler forward; each row of black spots
corresponds to a row of scales and the dark spot is at center of each
scale; dorsal and caudal fins barred, with a black ocellate spot at upper
caudal fin base; bases of last two dorsal rays with a pale spot enclosed
above by a brownish bar on base of fin; undersides in front of pelvics
plain in color; underside of head finely pigmented; dorsal side of head
and back dark brownish; lower lip or chin brownish; margin of anal
fin and outer edge of pelvic fins blackish; pectorals finely pigmented.
The coloration of the adult males is considerably different from the
94 PROCEEDINGS OF THE NATIONAL MUSEUM vol.99
females since the males lack the rows of spots on the sides and the ocel-
late black spot on upper caudal fin base; back and sides blackish
brown, gradually becoming paler underneath; sides of body with rows
of pale specks corresponding to center of each scale; dorsal and anal
fins faintly barred ; blackish color of body continuing to end of caudal
fin, forming a wide band on middle four-fifths of caudal fin, sharply
contrasting with the white dorsal and ventral edges of this fin; pec-
torals dark; margin of anal and of pelvics black edged; chin and
underside of head as in females.
Remarks.— This, new species traces down to Rivulus harti in the key
prepared by Regan (1912, pp. 495-496) but it differs from that
species as indicated in the key on page 83 and the counts differ
somewhat as indicated in table 13.
Named bondi, in honor of Dr. F. F. Bond, who collected this species.

HUBBSICHTHYS, new genus
Genotype: Hubbsichthys laurae, new species.
This new genus of Fundulinae is characterized by the free orbital
margin; eye diameter a little greater than the snout; interorbital
space flat, much wider than eye diameter; premaxillaries protractile;
lower jaw oblique; maxillary and anterior edge of the preorbital
oblique, not quite vertical, no angular pocket formed along front of
preorbital; fine conical teeth in upper jaw in two rows anteriorly, but
laterally forming a patch that ends in a sharp angular point poste-
riorly; teeth in lower jaw in two rows; dorsal origin in advance of
that of anal fin; dorsal origin equidistant between midcaudal fin base
and front margin of eye; anal origin very slightly closer to rear margin
of eye than midcaudal fin base; caudal fin rounded; gill rakers about
10 on lower part of first gill arch, short; gill membranes extending
forward to under pupil where they join forming a free fold; the row
of scales along middle of side much larger than those above and
below; base of caudal fin scaled.
Remarks. — The genus may be recognized from the American
genera related to Rivulus as discussed by Myers (1927) by having a
free orbital margin and from other genera by a combination of char-
acters, as dorsal origin in advance of anal origin; an enlarged row of
scales along midsides, with smaller scales in the rows above and below;
cleft of mouth evenly curved and oblique; preorbital edge oblique
without angular pocket at upper edge; flat interorbital space, and
small conical teeth in two rows in both jaws. From Chriopeoides
Fowler (Notulae Naturae No. 35, p. 4, 1939, Jamaica) with which
this new genus is related it differs by having the upper edges of the
preorbital a little farther forward than the lower corner, so that the
preorbital edge slants forward, while in Chriopeoides the slant is in
the opposite direction; scales on breast in front of pelvic bases smaller
than on sides, the middle row irregular, with about 12 scales, while in
Chriopeoides the midventral row is very regular on breast, as large as
scales on sides, and number 8 scales. There are 12 scales in a zigzag
row around caudal peduncle instead of 14 as in Hubbsichthys. Inter-
orbital space very slightly convex in Chriopeoides but flat and on
level of upper rim of orbit in Hubbsichthys.
One of the paratypes of Chriopeoides pengelleyi Fowler, A.N.S.P.
No. 68633, was kindly lent for examination by Henry W. Fowler, of
the Academy of Natural Sciences of Philadelphia.

Holotype. — U.S.N.M. No. 120999, a specimen, 14 mm. in standard
length, collected near Pampan, Estado de Trujillo, Venezuela, by
Dr. Arnoldo Gabaldon, in 1935 and probably in Rio Motatdn drainage.
Figure 13. — Hubbsichthys laurae, new genus and species: Holotype (U.S.N.M. No. 120999),
14 mm. in standard length. Drawn by Mrs. Aime M. Awl.
Description. — Certain detailed measurements and counts were made
on the holotype and these data are recorded in table 14.
In addition to the characters recorded in the generic description,
in the key, and in the table, the following is given: Eye about 1.2 or
1.3 in the flat interorbital space; head 3, depth 3.5, in standard
length; pectoral fins not quite reaching to opposite anal origin but
past middle of pelvics, the tips of latter extending a trifle past anal
origin; caudal, anal, and pectoral fins with posterior margins rounded;
the second ray of pelvic is longest; caudal fin scaled about one-third
to two-fifths out from its base.
Coloration. — General color in alcohol brownish, with a darker band
along midsides, somewhat broken by pale centers of scales; anal with
a black spot near middle of fin on posterior rays.
Remarks. — This new species may be distinguished from all other
related forms of cyprinodont fishes by means of the key. It differs
in regard to free margin of eye, forward slant of anterior edge of
preorbital, crowded scales on breast, origin of dorsal in front of that
of anal, and in coloration.
Named laurae, in honor of Laura Clark Hubbs (Mrs. Carl L. Hubbs).

additional species should be taken:
la. Tail prehensile, usually more or less in a curled condition; caudal fin absent;
head at nearly right angles to body (Hippoccampus)?^
lb. Tail not prehensile; caudal fin present; head not at right angles to body but
in same general axis.

anus and without interruption continues posteriorly as the lower lateral
keel on the tail region; dorsal and anal fins present; dorsal fin rays 38 to
44; rings on body about 19 or 20 + 23 to 27; pectoral fin rays about 19 or
20; dorsal origin in second or third ring in front of ring containing anal

>« Hippocampus punctulatus is recorded by R6hl (1942) from the coast of Venezuela but even with the aid
of Ginsburg's review of the genus (Proc. U. S. Nat. Mus., vol. 83, pp. 497-694, figs. 54-71, 1937) I do not know
what species he actually had. The common name in Venezuela is caballito de mar.

In 1943 (U. S. Nat. Mus. Bull. 180, p. 73) I included this genus
in the synonymy of Doryichthys Kaup but upon fm-ther consideration
I am incUned to recognize it as a distinct genus.

The following counts were made on the above hsted specimens:
Dorsal fin rays 37 in three counts, 39 in one; pectoral rays 13 in one
and 14 in three counts; body rings on trimk 14 in all four specimens,
and tail rings 35 in two, 36 in one, and only 28 body rings left in the
injured specimen; caudal fin had 10 rays in one count.
The coloration consists of dark brown upper side, sharply contrasting
with a pale grayish band along the dorsal side from snout to tail;
ventral side pale; caudal fin bordered with pale; dark brown streak
from lower jaw through eye to pectoral fin base; actual tip of lower
jaw pale and forming part of pale band on dorsal surface of head.

membrane folding between jaws; dentigerous surface of premaxillaries
not reflected outward and covering face of that bone with "shagreen";
two dorsal fins present; silvery lateral band present; mouth small, the
maxillary not reaching to e3'^e; air bladder and body cavity not
reaching anywhere near to opposite anal fin origin; first dorsal origin
notably in front of anal origin; pelvic insertions much closer to oper-
cular margin or upper angle of pectoral fin base than to anal origin;
about 5 or 6 scales forming a sheath anteriorly along base of anal
fin; margin of scales entire; distal margins of dorsal and anal fins
concave; ascending process of premaxillary a narrow based spine-
like projection; vertebrae in one count 16 + 24.
It differs from all other genera of Atherinidae by having the anus
far forward, equidistant between pelvic insertion and anal origin or
nearer pelvic base than anal origin in combination with the four
glandlilvc depressions on dorsal surface of snout and the body cavity
nowhere near reaching to opposite the anal fin origin.
The only other related atherine fishes with the posterior end of the
premaxillary dilated that have the anus far forward is Archomenidia
sallei (Regan), but that genus has the air bladder and body cavity
conspicuously extending some distance past the anal fin origin.
The only related genus of atherine fish with the four glandlike
depressions on the dorsal surface of the snout is Membras, but that
differs from Adenops in having the anus just in front of the anal -fin
origin.

I have made counts and measurements on the above-listed material
and have compared these with similar counts made on specimens from
Trinidad and Brazil. Because of a large variation and a small series
of specimens it is not possible to separate the Lago de Maracaibo
population from that of the Gulf of Venezuela or of Brazil. Perhaps
when an adequate number of specimens has been studied throughout
the range of this species, it may be possible to break it up into sub-
species.

Figure 15. — Coleotropis blackburni, new species: Holotype (U.S.N.M. No. 123205), 82 mm;
in standard length. Drawn by Mrs. Aime M. Awl.
Coloration. — In alcohol, plain except for silvery lateral band which
has a blackish dorsal border; a few dark pigment cells stiU visible on
posterior border of scales that occur above silvery lateral band.
Remarks .—ThiQ new species is related to Coleotropis starksi (Meek
and Hildebrand) from the Pacific side of Panama but differs from
that species by having I, i, 21 to I, i, 23 anal rays instead of I, i, 25
to I, i, 28. In addition C. blackburni has 44 to 48 scales instead of 41
to 42 as in C. starksi.
Named in honor of Capt. P. P. Blackburn, of the U. S, S. Niagara,
who preserved all the fishes collected in Venezuelan waters in 1924-
1925 reported upon in this contribution. It gives me great pleasure
to name this interesting species of silverside after Captain Blackburn.

Family MUGILIDAE: Mullets; Lisas
No careful comparison of European and American mullets has been
made; Mugil cepfialus therefore is usually considered to have a world-
wide distribution. However, my preliminary study of specimens of
M. cephalus from Europe compared with some American ones indi-
cates possible differences. Before any definite conclusion can be
reached a large series will have to be studied. I have not found any
specimen from Venezuela that could be definitely classified as cephalus,
and I have serious doubt that M. cephalus occurs along the east coast
of South America or in the West Indies.
During my study of the mullets of Venezuela I considered it neces-
sary to revise provisionally the genera of Mugilidae, since much con-
fusion exists in regard to genera. The results of this preliminary
revision have been published (Schultz, 1946).

reaches to the eye at a standard length of 50 mm., but in adults 150
mm. and longer the maxillary reaches well past the front of the orbit,
sometimes to under the front of the pupil. I am unable to find any
significant differences in any counts made on Venezuelan specimens
and other localities in the West Indies and Central America. The
origin of the dorsal fin is equidistant between tip of snout or a little
closer to tip of snout.
The following counts were made on Venezuelan specimens: Anal
rays III, 9 in 14; gill rakers 9 to 12 + 1 + 17 to 20 on first arch in 8
specimens; scales 38 in 1, 39 in 2, and 40 in 6 specimens.

U.S.N.M. No. 121796, 11 specimens, 74 to 240 mm., from mouth of
Cafio de Sagua, 25 km. north of Sinamaica, taken March 12, were
separated from the other specimens of this species taken at the same
place and date, U.S.N.M. No. 121792, because they appear to be more
elongate, with a more slender caudal peduncle, and the space from
tip of depressed first dorsal to origin of second dorsal is greater.
There is too much overlapping, however, to permit the consideration
of this lot as a new form.

U.S.N.M. No. 123134, a specimen, 127.5 mm. in standard length, from south
coast of Gulf, U. S. S. Niagara, November 7, 1924,
As this species has never been recognized since its original discovery
and probably the specimen before me is only the third one collected
and made known, I am giving the following rather full diagnosis and
a comparison with other species closely related to it:
The following measurements, expressed in hundredths of the
standard length, were made: Greatest depth of body 35.5; length of
head 43.9; length of snout 12.5; least width of bony interorbital space
4.97; diameter of eye 8.78; postorbital length of head 23.1 ; least width
of preorbital space 4.31; distance from tip of snout to rear edge of
maxillaries 19.0; length of longest gill rakers 3.37; length of caudal
peduncle or from rear base of last anal ray to midbase of caudal fin
21.4; least depth of caudal peduncle 14.3; length of pelvic spine 11.4;
length of spines of dorsal fin — first 5.49, second 10.1, third 18.3, fourth
19.5, fifth 14.9, sixth 12.8, seventh 12.4, eighth 11.4, ninth 11.2, tenth
13.7; length of anal spines — first 6.20, second 11.8, third 11.9; longest
soft ray of dorsal fin 17.9; of anal fin 19.6; of pectoral fin 23.0; of pelvic
fin 20.4; longest ray of caudal fm 24.8; distance from tip of snout to
origin of dorsal fin 42.6, and to origin of anal fin 63.0; snout tip to
pectoral fin insertion 35.5 and to pelvic insertion 37.4.
118 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 99
The following counts were made: Dorsal rays X,14; anal rays III,
7; pectoral fin rays i, 16-i,16; branched caudal fin rays 8 + 7=15;
pelvic rays I, 5-1, 5; gill rakers on first gill arch 7 + 1 + 13; number of
transverse scale rows just above lateral line from upper edge of gill
opening to midbase of caudal fin 75; pores in lateral line 55 with 8
additional ones on caudal fin; scales from dorsal origin to lateral line
11 or 12 and from base of first soft ray of dorsal to lateral line 8;
scales from anal origin upward to lateral line 19 or 20 in an oblique
row; zigzag scales around least width of caudal peduncle 39 or 40.
Body a little compressed, greatest depth through middle of spiny
dorsal; caudal peduncle a little compressed; pelvics inserted under base
of pectoral fins; dorsal origin over base of pectorals; anal origin under
base of second or third soft ray of dorsal fin and anus close in front of
anal fin; distal margin of caudal fin truncate or a little rounded when
fully distended ; distal margins of soft dorsal and anal fins rounded, that
of pectoral rounded with the seventh to ninth branched rays longest,
counting down from the dorsal edge; third and fourth dorsal spines
longest, the fourth projecting a little beyond third and fifth spines;
second and third anal spines projecting about the same amount;
scales small, ctenoid, covering body and bases of all fins, and the scales
extending two-thirds the way out on the rays of caudal, pectoral, and
pelvic fins but not over halfway out on soft dorsal and anal fins; scales
occur only on the basal third of the dorsal spines, the membranes being
naked; scales occur on operculum and cheeks and forward on top of
head to a line connecting across rear of orbits, the rest of the top of head
and snout naked; underside of head naked; scales in front of pelvics
smaller than elsev/here on body; lower jaw projecting but not quite enter-
ing profile ; gill membranes free from isthmus, extending far forward ; gill
rakers moderately long, not quite so long as the least width of the
preorbital; each pair of nasal openings separated by a narrow dermal
isthmus; the anterior nasal opening, tubelike, with a fringed dermal
flap posteriorly; the rear opening with a low fringed tube; interorbital
space flat; maxillary reaching to under or a little past rear edge of
pupU; teeth on dentary in an enlarged row of short cacinelike teeth
with a few tiny ones at sides but in a band anteriorly; teeth on upper
jaw similar but in a narrow band on sides; villiformlike teeth on
vomer and palatines, but apparently no teeth on tongue or pterygoids.
Color in alcohol. — Lower sides with 7 dark brown vertical bars, about
twice width of pale interspaces; these bars join along middle of sides to
form an irregular mottled pattern; upper sides dark brown with
several narrow oblique bars ending at lateral line; posteriorly under
soft dorsal two of the vertical dark brown bars are visible and two more
on caudal peduncle, these continuous from those ventraUy; base of
caudal fin with 4 dark brown spots surrounded with paler tan; caudal
fin with numerous dark brown spots; base of pectoral fin with dark
ICHTHYOLOGY OF VENEZUELA — SCHULTZ 119
brown blotch circled with pale, then posteriorly at base of fin a dark
circle; a dark bar extends downward from eye ending on subopercle;
pelvic fins very dark brown or blackish; anal and pectorals brown;
membranes near tips of dorsal spines anteriorly blackish; soft dorsal
mottled with brownish.
Paralabrax dewegeri is related to that group of fishes now represented
by the following species: humeralis Cuvier and Valenciennes, cal-
laensis Starks, castelnaui Jordan and Eigenmann, clathratus Girard,
nebulifer Girard, maculatofasciatus Steindachner, maculata Howell-
Rivero, tortugarum Longley, and beta HUdebrand.
From nebulifer and maculatofasciatus (of Pacific coast), which have
the third dorsal spine much longer than the fourth, it differs by having
the third dorsal spine a little shorter than the fourth, and in having
fewer scale rows above the lateral line; clathratus (of Pacific coast) has
more scales, 90 to 100, and more gill rakers, 20 to 24 on the lower part
of first arch, instead of 75 and 13 or 14 respectively for dewegeri. Two
other Pacific coast species, humeralis and callaensis, have 18 to 22 gill
rakers on the lower part of first gill arch and the former has too many
scales. Paralabrax maculata Howell-Rivero of the Atlantic has but
X,ll dorsal rays and only 45 scales. P. castelnaui from Rio de
Janeiro has but X,12 dorsal rays. There remain two species that
may be related to the Venezuelan one, but not closely: They are
Serranus tortugarum Longley (Carnegie Inst. Washington Year Book
No. 34, p. 87, 1935; Longley and Hildebrand, Carnegie Inst. Washing-
ton Publ. 517, p. 238, fig. 8, 1940 [south of Tortugas, Fla.]) and Serranus
beta Hildebrand in Longley and Hildebrand (l. c), p. 239, fig. 9, 1940
(south of Tortugas, Fla.). Both of these species have too few soft
dorsal rays, X,ll or 12 and X,12, and, in addition, too few scales, 50
or 60, respectively.

Family CARANGIDAE: Pampanos
The material representing this family from Venezuela is rather
scanty. A few genera that are to be expected in Venezuelan waters
do not occur in the national collection, but undoubtedly they will
be taken when adequate collections are made. I am copying Meek
and Hildebrand's "Key to the Genera" of this family from "The
Marine Fishes of Panama," part 2, pp. 332-333, 1925. This key,
however, has been somewhat modified and more or less restricted to
cover the Venezuelan coastal waters.

In an attempt to determine what name should be applied to the
Oligoplites inhabiting Lago de Maracaibo I made a study of nearly all
the specimens of this genus in the United States National Museum.
My results were pubhshed (Schultz, 1945d) and it is not deemed
necessary to repeat them here. In all, seven species were recognized,
three in the Atlantic and four in the Pacific, all in American waters.

U.S.N.M. No. 121807, a specimen, 112 mm., mouth of Cano de Sagua, 25 km.
north of Sinamaica, March 12, 1942.
This characteristic genus and species in general resembles Anisotre-
mus but differs in the very narrow preorbital, its least depth is con-
tained about 3 times in the eye and 9 times in the head; in addition
the gill membranes form a broad fold across the isthmus as in the
Kyphosidae, but the gill membranes are naked. In Anisotremus the
posterior edge of the gill membranes form an acute angle over the
isthmus, and in Genyatremus this is evenly curved. There are no
scales on the soft rays or membranes of the dorsal and anal fins, only
a sheath of scales basally, in Genyatremus, whereas in Anisotremus the
median fins are scaled wholly or in part, always some scales on the
interradial membranes. The dorsal rays are XIII, 12 and anal III,
10 in both specimens from Venezuela. The pectoral fins are equal in
length in the distance from the nostrils to rear of head. The margins
of the dorsal fins are blackish; there is some indication of a dark,
wide, wedge-shaped saddle in front of the dorsal fin, and another over
the region of the orbits, both barely discernible in the alcoholic
specimens.

The young of this species and of E. gula are separated Nnth con-
siderable difficulty, and I am not positive that my identification of
specimens under 25 mm. is correct.
In the Maracaibo Basin specimens, in addition to the difference in
depth of body between E. gula and E. argenteus, I observed that the
ICHTHYOLOGY OF VENEZUELA — SCHULTZ 141
tip of the lower jaw or lip was almost invariably without scattered
black pigment in argenteus, whereas in gula the tip of the lip of lower
jaw almost always had several black pigment cells somewhat em-
bedded. The character of the area over the premaxillary process and
scales meeting in front of this groove is of no value on small specimens.
However, specimens from the coast of Venezuela south of the Gulf of
Venezuela had their chins pigmented. Thus specimens 25 mm. and
shorter can be separated only on their slenderness as compared with
those of gula which are a little more robust.

(Genotj'pe, Diapterus auratus Ranzani.)
It is with considerable reluctance that I add two new names to the
genera Diapterus and Eugerres in my study of the Venezuelan forms.
These genera have not been revised to my knowledge, and no one has
as yet determined the constancy of the niimber of anal spines in large
series of specimens. This should be done when the genera are revised,
and then the validity of these new species as well as others may be
evaluated. My counts, however, indicate a rather constant number
of rays for most of the fins, and there appears to be little variation in
the number of scales or gill rakers for any species from one locality.
The following key is based on specimens collected in Venezuelan
waters, as well as on other materials in the national collections from
the Western Atlantic:
142 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 99
la. Anal rays 111,8.
2a. Gill rakers on lower part of gill arch 10 or 11; dusky bars on sides of young
but adults with dusky punctulations and no bars; second dorsal spine a
little shorter than third, both shorter than head, the second contained
nearly 4 times in standard length; second anal spine strong, but a little
shorter than third, the second anal spine 1.8 in head and 1.5 in second
dorsal spine; area over premaxillary groove free of scales in young but
covered with small scales in large specimens.
Diapterus olisthostomus (Goode and Bean)
26. Gill rakers on lower part of first arch 15; second dorsal spine a little shorter
than third, the second spine about 1}^ in head; second anal spine enlarged,
a little longer than third spine, the second 1.5 in head and lYs in second
dorsal spine; second row of scales below lateral line continuous to end of
caudal; area over premaxilary processes on top of head free from scales;
no dark stripes or distinct bars visible.
Diapterus limnaeus, new species
16. Anal rays II,i,8 or 11,9.
3a. Anal rays 11,9; gill rakers on lower part of first arch 14 or 15, rarely 16;
second dorsal spine a little shorter than third, the second spine contained
1.2 to 1.4 in head and about 3.2 to 3.5 in standard length; second anal
spine 1.4 to 1.6 in head and 4 to 4.5 in standard length; second row of
scales below lateral line continuous to caudal fin.
Diapterus rhombeus (Cuvier)
36. Anal rays II,i,8: gill rakers 10 or 11 on lower part of first arch; second dorsal
spine a little shorter than third, about 1}^ to IJ^ in head and 3.5 to 3.75

in standard length, collected by Leonard P. Schultz in Lago de
Maracaibo at Maracaibo Yacht Club, May 16, 1942.
Description. — Certain measurements were made on the holotype
and these are recorded in hundredths of the standard length in
table 18.
The following counts were made: Dorsal rays IX, 10; anal rays
111,8; pectoral rays iii,12-iii, 12; scales from upper edge of gill opening
to midcaudal fin base 40; scales from base of first soft ray of dorsal
to lateral line 4, and 9 from base of first anal spine to lateral line;
gill rakers on lower part of first arch 15.

head; maxillary reaches to below anterior margin of pupil; area
above premaxillary processes broad and free from scales; preorbital
edge smooth; posterior margin of preopercle serrate; gill rakers short,
strong, on lower part of first arch; second dorsal spine not reaching
quite to tip of third; second anal spine strong, reaching past third
which is slender; second dorsal spine 1.1 and second anal spine about
1.4 in head; distal margin of dorsal fin concave, that of anal fin a
little concave; pectoral fin pointed, the second branched ray longest,
and reaching opposite base of third anal spine; third dorsal spine
when depressed reaches to opposite base of fourth soft dorsal ray;
second anal spine when depressed reaches past base of last anal ray;

profile of head slightly concave over eyes; first soft ray of pelvics
with a short filament, the pelvic spine reaching nearly past anus;
second row of scales below lateral line continuous to caudal fin base;
greatest depth of body at origin of dorsal fin.
Color. — Plain silvery without dark streaks on sides and no dark
bars; distal margin of dorsal fin black edged; a few blackish pigment
cells on interradial membranes of dorsal and anal fins but not forming
spots or blotches; tips of rays of caudal fin with a few dark pigment
cells.
Remarks. — This new species differs from all others of the genus in
the Atlantic as indicated in the key on pages 141 and 142, chiefly in
having 15 gill rakers in combination with a smooth preorbital, no
scales on area over premaxillary groove, and the second dorsal

spine not reaching quite to tip of third dorsal spine. From D.
peruvianus of the Pacific with which this new species is most closely
related, it differs by having 15 gill rakers instead of 12 or 13.
Named limnaeus (meaning "lake") in reference to its occurrence in
Lake Maracaibo.

specimens mentioned under plumieri that have the third anal ray
simple but cross striated.
This modification of the third anal ray has been considered by
Meek and Hildebrand as of specific significance, but its occurrence
in other species causes me to cast serious doubt on its validity as a
dependable character when considered alone. However, in view of
the small series of specimens for certain species of Diapterus, I am
tentatively referring the above listed specimens to evermanni.

U.S.N. M. No. 121718, 6 specimens, 45 to 100 mm., Lago de Maracaibo at
Yacht Club, Maracaibo, March 5, 1942.
There are four specimens measuring 37.5 to 51 mm,, from Lago de
Maracaibo at Yacht Club, A/faracaibo, that I have separated from the
February 27 collection (U.S.N.M. No. 121715) and I have placed
them in a separate jar that bears U.S.N.M. No. 121725. They are
referred to this species but vary from it in having II, i, 7 (in one
specimen) and II, i, 8 (in three specimens) instead of the usual three
anal spines. The third anal ray is usually a small slender spine but
in the four specimens under consideration here the third ray is simple
with a few cross-striations near its tip. I cannot otherwise distinguish
these four specimens from typical specimens of D. plumieri.
Should a larger series become available to someone and should these
prove to represent an undescribed species, I have carefully measured
two specimens and recorded the data in table 18. In addition, the
following description was drawn up.
Dorsal rays VIII, 11 (in one) and IX, 10 (in three); pectoral rays
IV, 12 in two counts, V, 11 in three, V, 12 in one; gill rakers on lower
part of first gill arch 14 or 15 in all four specimens.
Greatest depth of body 2.5 or 2.6, head 2.7 or 2.8 in standard length;
snout 3.2 to 3.5, eye 3.6 to 3.8, and postorbital length of head 2.3
or 2.4, all in length of head; maxillary reaches not quite to below
anterior margin of pupil; area above premaxillary groove naked;
preorbital edge smooth or slightly rough; rear margin of preopercle
serrate; gill rakers strong and short; second dorsal spine long, reaching
past third dorsal spine and longer than head, contained 2.5 or 2.6 in
standard length and equal to or a little longer than greatest depth of
body; second anal spine long and strong, a trifle shorter than head,
about three times in standard length; distal margins of dorsal and of
anal fins concave; pectoral fins long, pointed, the first or second
branched rays longest and reaching to opposite origin of anal fin;
second dorsal spine when depressed reaches to opposite bases of
seventh or eighth soft dorsal rays; second anal spine when depressed
reaches to caudal fin base or nearly to it; profile of head barely concave
over orbits; first soft pelvic ray with a filament, the pelvic spine shorter
but reaching a little past anus; third row of scales below lateral line
continuous to caudal, rarely the second row; greatest depth of body
at origin of dorsal fin.
Color. — Each row of scales has a darkly pigmented area giving the
appearance of streaks of small spots along each row of scales along
upper sides; distal margin of dorsal fin blackish, and rest of fin dusky,
except the basal sheath of scales, which are white; caudal fin dusky;
anal dusky forward; pectorals pale; snout dusky and dorsal tip of
150 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 99
upper lip dusky, rest of upper and lower lips white; these young
specimens have 4 to 7, usually about 5, narrow vertical dusky bars on
sides.
In addition, I refer to this species a small specimen, 17 mm. in
standard length, collected April 6, 1938, by Dr. F. F. Bond in a
coastal lagoon 15 Ion. north of Maracaibo.
Family SCIAENIDAE: Croakers; Corvinas
During my study of this family I carefully dissected the skin and
scales from the dorsal and lateral surfaces of the head for the purpose
of determining which genera have "cavernous skulls" and found that
all of the genera listed herein have the narrow bony bridges and sunken
spaces, otherwise called cavernous skulls. In those genera and
species with broad interorbital spaces similar to Stellifer and with
thinner skin or scales the caverns are more easily felt by touch than
in certain other genera such as Equetus.
The counting of the number of scale rows above the lateral line is
subject to error since certain rows run together as they approach the
lateral hne. To avoid this error and keep my counts consistent, I
counted the rows directly above the lateral line.

Dr. F. F. Bond collected 45 specimens 17 to 57 mm. in standard
length in the Rio Apure at San Fernando de Apm'e on February 16,
1938. These small specimens warrant a brief description because
this and allied species are not well known and are rather scarce in
museum collections. In fact, for several reasons, among them the
small size and coloration of the specimens, I am not even sure these
specimens are P. schomburgkii.
The following counts were made: Dorsal rays X, I, 24 in one, X, I, 25
in three, X, I, 26 and X, I, 27 in four each, one count each of X, I, 28
and X, I, 29. Anal rays II, 6 in 14 counts. Pectoral rays ii, 16 in two;
ii, 17 in five; and ii, 18 in three counts. Gill rakers on first gill arch
5 + 1 + 10 in three counts, 5 + 1 + 11 in two, 6 + 1 + 10 in six,
and 6 + 1 + 1 1 in three counts. Number of vertical scale rows from
upper edge of gill opening to midbase of caudal fin 81 in one count,
82 in two, 83 in two, 84 in one, 85 in six, 86 in one, and 87 in one count.
There were 8 scales from the base of the first soft dorsal ray to lateral
line in 14 counts and from the anal origin to lateral line 9 scales in
four and 10 in eight counts.
The coloration is somewhat uniform. A series of about five to
seven vertically elongate brown spots occur along the middle of the
sides; on the smallest specimens only occur four brown blotches on
the back along base of dorsal fin, the first in front of spiny dorsal,
second along rear of base of spiny dorsal, and two along base of soft
dorsal; opercle of all specimens with a brownish blotch; tips of dorsal
spines blackish; soft dorsal with a row of small dark spots extending
along its middle on the membranes; caudal fin dusky.

U.S.N. M. No. 128251, 1 specimen, 270 mm. in standard length, Gulf of Vene-
zuela, depth 35 feet, U. S. S. Niagara, December 1, 1924.
This specimen has X-I,28 dorsal rays and 11,9 anal rays. The giU
rakers on the first giU arch number 3+1 + 9 and are about one-third
the diameter of the eye. The vertical scale rows above the lateral
line number 120, and there are about 13 scales from base of first soft
dorsal ray to lateral line and about 15 from anal origin to lateral line.
The pectoral fin has about 16 rays. The pectoral fins extend con-
siderable distance past tips of pelvics. The soft dorsal fin is not
heavily scaled except its basal two-thirds but caudal and anal fins
are thickened with scales over two-thirds the way out.

Figure 29. — Cynoscion maracaiboensis, new species: Holotype (U.S.N.M. No. 121742), 255
mm. in standard length. Drawn by Mrs. Aime M. Awl.
Body elongate, somewhat compressed, the head about 3.25, depth
about 4.25, in standard length; anterior profile rounded, the greatest
depth at origin of dorsal; snout a little longer than interorbital space;
eye nearly equal to interorbital space, the latter 5% in head; rear
edge of maxillary under rear margin of eye ; two pairs of canines at
midfront of premaxillary, these teeth hooked backward, the posterior
pair largest; both upper and lower jaws with a band of villiform teeth,
along the outer margin of which are widely spaced short canine teeth ;
preopercle without spines, with a membranous edge; opercle ending
in a wide membranous edge, the portion between the flat spinelike
angles at upper posterior end covered with minute scales; scales on
head smooth but those on body ctenoid; scales above lateral line
anteriorly much smaller than those between soft dorsal fin and
lateral line; scales below lateral line anteriorly much larger than the
scales above lateral line; pectoral fins not quite reaching opposite
tips of pelvic fins; posterior margin of spiny dorsal fin nearly straight,
the fourth spine projecting past the third when fin is distended;
distal margin of soft dorsal nearly straight, the anterior rays longest,

gradually becoming a little shorter posteriorly; middle rays of caudal
fin longest; distal margin of anal fin nearly straight, or slightly
rounded ; distal margins of paired fins rounded ; origin of second dorsal
fin equidistant between midcaudal fin base and front of eye; anus equi-
distant between pelvic insertion and midcaudal fin base; base of anal
fin 3.5 times in base of second dorsal fin; pelvic fins reach one-half the
way to the anus; least depth of caudal peduncle about 3 times in its
length.
Coloration. — Silvery on sides, white below, dusky above; back
along base of spiny and soft dorsal brownish; base of each lobe of
caudal fin with some brownish pigment; spiny dorsal fin dusky brown
and soft dorsal and anal fins pale dusky; a brownish spot at upper
edges of pectoral fin base; pelvics pale; pectoral fin with a little
brownish pigment; upper edges of maxillary and premaxillaries brown-
ish; peritoneum white.
Remarks. — This new species of Cynoscion is abundant in Lago de
Maracaibo, where large numbers are caught on hook and line and by
jigging. It is usually in the market at Maracaibo.
Cynoscion maracaiboensis, with its ctenoid scales, with scales only
on the basal parts of soft dorsal and of soft anal fins, and with but
18 or 19 soft rays in the dorsal fin, is readily distinguished from all
other species of Cynoscion in American Atlantic waters except C.
acoupa. C. steindachneri, C. nothus, C. regalis, C. arenarius, and
C. jamaicensis all have 20 or more soft dorsal rays. C. striatus has
about 19 or 20 soft dorsal rays, 8 or 9 soft anal rays, and ver}^ large
scales, about 52 to 56 pores and 62 to 66 vertical scale rows above the
lateral line, whereas C. maracaiboensis has 54 to 59 pores and 79 to
85 scale rows respectively. The number of gill rakers on a specimen
of C. striatus numbered 6 + 1 + 16, including all rudiments that
showed any development.
Cynoscion maracaiboensis is most closely related to C. acoupa
(Lacepede) but differs from it by having 18 or 19 soft dorsal rays, 79
to 85 vertical scale rows above the lateral line, and 54 to 59 pores in
lateral line instead of about 85 scale rows above, 19 to 21 soft dorsal
rays, and about 55 to 66 pores in the lateral line, according to Ribeiro
(Arch. Mus. Nac. Rio de Janeiro, vol. 17, p. 36, 1915) and Eigenmann
(1912).

G. Zuloaga, William Phelps, Jr., R. Sherman, May 12.
3 specimens, 41 to 63 mm., near Caripito, Dr. William Beebe.
The above specimens are referred to this species with some uncer-
tainty since the numbers of fin rays do not exactly agree and both
collections may represent new subspecies of macro phthalma. The
specimens from the Rio Guarico have the following counts: Dorsal
rays XXI, 13, XXII, 12; anal rays III, 7 and III, 8 while those from
near Caripito have XXII, 11; XXII, 12; XXII, 12; anal rays 111,9;
III, 9; III, 9. The number of scale rows are about 62 to 64 in both
collections and 26 scales in a zig-zag row around caudal peduncle.
The coloration in all specimens consists of about 7 blackish doubled
crossbars, the middle of each dark bar is pale; oceUated caudal spot
prominent; a dark band past eye to end of opercle, thence represented
along anterior midside by intensification of pigment in each bar,
interspaces pale; no humeral spot; caudal fin slightly barred or plain.

ICHTHYOLOGY OF VENEZUELA — SCHULTZ
175
U.S.N. M. No. 121620, 98 specimens, 26 to 139 mm., Rfo Palmar near Totuma,
about 100 km. southwest of Maracaibo, February 21, 1942.
Recently I described (Schultz, 1944d) a new species of Petenia from
Colombia. In table 20 the species P. kraussi and P. myersi Schultz
are compared. H. W. Fowler (Proc. Acad. Nat. Sci. Philadelphia,
vol. 97, pp. 133-135, figs. 46, 47, 1945) described Coquetaia amploris
from the Rio Coquetd, but this is a synonym of Petenia myersi
Schultz; they came from the same river.

Genus SPHOEROIDES Anonymous

The correct identification of the puffers in the western Atlantic
referred to the genus Sphoeroides is very difficult if not impossible for
certain forms. There appears to be so much variation in size of
eye and head and in other morphological characters that most keys lead
to doubtful identifications. Since no revision of tliis genus has been
802207—49 13
194 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 09
made and sufficient material of the various forms described are lacking
for study, the following tentative key must be used with caution for
the area adjacent to the coast of Venezuela and northward. A species
difficult to place is Sphoeroides harperi Nichols (Bull. Amer. Mus.
Nat. Hist., vol. 33, art. 3, p. 81, 1914) from Cape Sable, Fla. This
species may be maculatus.
Meek and Hildebrand ("The Marine Fishes of Panama", part 3,
p. 813, pi. 77, 1928) use the name Sphoeroides marmoratus (Ranzani)
for a species covered v/itli minute imbricated scales that lacks the line
of black spots set off below the dark coloration of upper sides. How-
ever, Tetraodon marmoratus Ranzani (Dissertationes Quat. NoviComm.
Acad. Sci. Inst. Bonon., vol. 4, p. 73, pi. 10, figs, la, lb, 1840) as
represented by the figures is definitely not the same species as the
one illustrated on plate 77 of Meek and Hildebrand. I see no reason
at present why T. marmoratus Ranzani cannot be considered a synonym
of Sphoeroides spengleri as currently recognized. Specimens of
spengleri from Brazil appear to be the same as those from Panama and
the West Indies.
Sphoeroides marmoratus Meek and Hildebrand (not of Ranzani) I
refer to Sphoeroides eulepidotus (Metzelaar), basing my opinion on
several small series in the national collections.
The color patterns of maculatus and nephelus and the imbricate
scales indicate that eulepidotus is very closely related and possibly not
distinct from nephelus. I do not find any specimens of the typical
color pattern of maculatus south of the Carolinas in the national col-
lections.
KEY TO CERTAIN SPECIES OF SPHOEROIDES
la. Lower sides with a line of dark bars or roundish spots a little below and
well set off from darker ground color of upper sides and back, these bars
or spots numbering 5 in front of the pectoral base and 7 or 8 behind it,
totaling 12 or 13.
2a. Dark spots in a line roundish to oval in shape and black spot at lower
rear base of pectoral not quite reaching to middle of pectoral fin base
and little or no darker than others in line; a black bar across caudal fin
distally and another basally, separated by a pale bar; back variably
light spotted and dark spotted; least distance between bases of nasal
tubes about 5 to 7 times in the snout; postorbital length of head 1.5 to
2 times in snout; dermal papillae often present on sides; body often
with prickles in front of dorsal and anal fins; distal margins of dorsal
and anal fins rounded; dermal cirri often occurring on the sides of young
specimens Sphoeroides spengleri (Bloch)
26. Line of dark bars vertically elongate and extending up into dark ground
color of .sides; black spot or bar in axil of pectoral much darker than
any of others in the line and usually reaching up to or above midpectoral

2c. Line of dark bars vertically elongate but hourglass-shaped behind pectoral;
black spot in axil of pectoral intensified but not reaching above middle of
base of pectoral; upper part of body brownish and overlaid with numerous
very small circular-shaped white blotches everywhere; caudal fin plain
pale in color; least distance between bases of nasal tubes about 4.5 to 5
times in snout; postorbital length of head 1.5 to 1% in snout; body prick-
ly anteriorly and covered with small imbricated scales; prickles usually
with 4-pointed bases; distal margin of dorsal fin truncate, that of anal
rounded Sphoeroides nephelus ^^ (Goode and Bean)
16. Line of dark bars or spots absent, or, if present, not separated from dark
ground color of sides and back.
3a. Back darkish (often greenish when alive) with pale lines forming a coarsely
reticulated pattern and the sides have small dark spots, more numerous
with age, but fading ventrally so that the belly is white as usual; caudal
fin more or less darkish with a pale bar across the fin a little closer to its
base than distally; scales not noticeably developed although anteriorly
the body is prickly; least distance between nostrils 2.75 to 3 times in
snout; postorbital length of head 1.2 in snout; distal margin of dorsal
truncate or shghtly rounded Sphoeroides testudineus (Linnaeus)

blackish spot, somewhat vertically elongate, on middle of sides a
little in advance of dorsal origin; sometimes a pair of dermal cirri on
middle of back; brownish color of back with small pale specks or spots;
body not covered with small imbricated scales although small glandu-
lar-like scales occurring irregularly on body; body prickly anteriorly;
caudal fin with a dark bar distally and one basally separated by a
pale bar; least distance between bases of nasal tubes about 5 to 6.25
times in snout; postorbital length of head about 1.75 to 2 times in
snout; distal margin of dorsal fin truncate; that of anal truncate or a
trifle rounded; outer rays of caudal fin a little longer than others, so
that distal margin of this fin is slightly concave.

in rows, their number apparently increasing with age; caudal fin usual-
ly, except in larger specimens, with a pale bar across middle separat-
ing more or less distinct darker bars distally and basally; body every-
where covered with numerous very small imbricated scales; least dis-
tance between bases of nasal tubes contained 4.5 to 6 times in snout;

Suborder DIODONTOIDEA
Family DIODONTIDAE: Porcupinefishes
Genus DIODON Linnaeus
Diodon Linnaeus, Systema naturae, ed. 10, vol. 1, p. 334, 1758. (Genotype,
Diodon hystrix Linnaeus.)
Two species of Diodon — hystrix and holacanthus — are currently
recognized, but after examining a rather large series of both as indenti-
fied by several ichthyologists in the past, I find so much overlapping
in the two forms that I must cast serious doubt on their distinctness.
I notice that specimens up to 50 to 200 mm. in standard length have
relatively longer frontal spines than postpectoral spines, some dermal
cirri along lower sides of body and usually a pair under the chin.
On all the large specimens of Diodon, however, I fail to locate these
dermal cirri, and the frontal spines appear to be shorter than the
postpectoral ones, but this is caused by more of the base of the frontal
spines being embedded in the skin. The genus is in need of revision.
Provisionally I am combining hystrix and holacanthus because I am
unable to separate the two species as based on the material before me
from the Atlantic and Pacific Oceans.

Order GOBIESOCIFORMES
Family GOBIESOCIDAE: Clingfishes; Trepadores
During my attempt to identify the Venezuelan specimens of cling-
fishes in the national collections, it became clear to me that the Amer-
ican Gobiesocidae were in a state of confusion and were in need of
revision. This was necessary before I could determine the genus or
species to which the Venezuelan clingfishes belonged. After 3 months
of work, a manuscript was prepared and published (Schultz, 1944e).
The following key was modified from that publication so as to key
out all American genera, and it includes only those species that have
been reported from Venezuela:

THE WEEVILS OF THE GENUS TACHYGONUS IN THE
UNITED STATES NATIONAL MUSEUM, WITH DESCRIP-
TIONS OF NEW SPECIES
By Oscar Monte ^
The author received from the United States National Museum to be
studied a fine collection of weevils of the genus Tachygonus ^
Schoenherr numbering 47 specimens, comprising 20 species, of which
12 are new to science, some of these being represented by unique types.
There are also several new geographical records.
He takes the opportunity to express his thanks to the authorities of
the United States National I\Iuseum for their permission to study this
material and to L. L. Buchanan, of the Bureau of Entomology and
Plant Quarantine, for the offer of specimens in his charge for the
study of this interesting genus from South and Central America.
The author is greatly indebted also to Mrs. Ruth C. Altieri for making
the fine illustrations.
The type specimens of new species described herein are in the col-
lection of the United States National Museum. Certain paratypes
have also been deposited, as indicated in the text, in the Monte
collection.
TACHYGONUS RUFUS Hustache
Four specimens, Vi^'osa, Minas Gerais, Brazil, April 14, 1933, col-
lected by E. J. Hambleton, taken on an undetermined species of
Apocynaceae. The original description was based upon three speci-
mens collected at Jatahy, Goiaz, Brazil.
^ The author of this paper was connected with the Institute Biol6gico, Sao Paulo, Brazil.
He died on July 1, 1948, after his manuscript had been submitted for publication. — Editor.

Three specimens have the posterior tibiae blackish. Tliis character
is not mentioned in the original description; the fourth specimen
has the tibiae of the same color as the elytra, and this color is variable
from reddish yellow to ferruginous. The pectinate white scales are
not so scattered. The author thinks such characters do not differ
sufficiently to warrant a varietal description.
Length 1.65-1.73 mm. (type 1.5 mm.) ; width 1.13 mm.
TACHYGONUS BUCHANANI, new species
FiGUEE 21
Black, shining, the anterior and intermediate legs and posterior

Four specimens, San Mi<?iiel, Peru, two collected on September 1.
1911, and the other two, including the type, in July 1911, by the Yale
Peruvian Expedition, at G,000 feet. One paratype in the collection
of the author.
These specimens suggest T. rufovanus Kirsch, described from Peru,
because one of them has black patches on the elytra placed as called
for in the original diagnosis of this species, but mirus differs by having
the tibiae and base of femora darker, by having the pronotum not
densely pitted, the elytra elongated, the femoral teeth, of which four
are well developed, different, and in being larger.

THE SPECIES OF ICHNEUMON-FLIES OF THE GENUS
CARDIOCHILES OCCURRING IN AMERICA NORTH OF
MEXICO
By YiNG-Tou Mao
The Cardiochilinae are a comparative!}' small subfamily of
ichneumon-flies of the family Braconidae. Cardiochiles Nees is the
only genus in North America. It is a distinct group, differing rather
noticeably from other Braconidae in having the third abscissa of
radius arched forward (pi. 4, figs. 4, 5) . The species tend to fall into
two well-defined groups, one with hairy eyes and the habitus of a
microgasterine and the other with bare eyes and the habitus of a
sawfly. Although apparently best represented in the southern part of
the United States, Cardiochiles occurs as far north as southern Canada.
Little is known concerning the host relationships of members of the
genus. The hosts are probably always lepidopterous larvae, but few
species have been reared. C. nigriceps Viereck is a conspicuous excep-
tion. It has been obtained abundantly from larvae of the tobacco hwd.-
worm. Heliothis vlrescens (Fabricius).
This study was carried out under a fellowship granted by the
Science, Education and Art Division, Department of State, Wash-
ington, D. C, U. S. A. The problem was suggested by C. F. W. Muese-
beck. Division of Insect Identification, U. S. Bureau of Entomology
and Plant Quarantine, to whom the author is very much indebted for
his guidance during the course of the investigation. Thanks are due
to Dr. H. K. Townes, Jr., R. A. Cushman, and A. B. Gahan of the
same Division for their valuable suggestions and criticisms. The
author is also indebted to Dr. E. A. Chapin, curator of insects, U. S.
National Museum, for the use of facilities at the Museum, and to Miss

M. M. Carpenter for arranging interlibrary borrowings. In addition,
thanks are due E. T. Cresson, Jr., of the Academy of Natural Sciences
of Philadelphia, for the loan of the Cardiochlhs collection of that
institution for study and to Prof. H. B. Hungerford, of the University
of Kansas, for the loan of the type of Cardiochiles nigroclypeus
Viereck.

When he described this species Viereck suggested that it might prove
to be only a race of viator or seminiger. It is quite distinct from
viator, differing in the much shorter galea and labium, in the dark costa
and stigma, and in not having apex of hind tibia expanded into a
strongly flaring process. Essentially it is very similar to seminiger
(Cresson) and perhaps is only subspecifically distinct, but for the pres-
ent at least it seems advisable to give it specific rank. It may be
separated from seminiger by the following color differences : Pronotum
black, median part of lateral face sometimes red or yellowish brown ;
anterior part of mesoscutum, or at least anterior part of median lobe,
black ; fore and middle femora largely black or piceous. The middle
lobe of the mesoscutum slopes more gradually to the pronotum than in
seminiger (pi. 4, figs. 6, 7), and the first intercubitus is angulate and
often appendiculate below the middle.

A KEVIEW OF THE MITES OF THE FAMILY
CHEYLETIDAE IN THE UNITED STATES
NATIONAL MUSEUM
By Edward W. Baker
The family Cheyletidae Leach, 1814, as previously considered in-
cluded two groups of mites, those with small, poorly developed, non-
grasping palpi {Myobia^ etc.) and those with large, highly developed,
grasping palpi {Gheyletus^ etc.). The former are parasitic mites and
are adapted to live on such hosts as birds, snakes, and rats, while
the latter are primarily free-living predators.
Ewing (Proc. Ent. Soc. Washington, vol. 40, No. 7, p. 180, 1938)
erected the subfamily Myobiinae to include those mites of the genus
Myohia and its generic derivatives. In this paper, Myobiinae is raised
to family rank and is considered to include the following genera:
Amorphdcarus Ewing, Harpyrhynchus Megnin, Myohia Heyden,
Ophioptes Sambon, Picobia Haller, Protomyohia Ewing, Psorergates
Tyrrel, Radfordia Ewing, and Syringophilus Heller.
The family Cheyletidae is now considered to include the following
genera : Acaropsis Moquin-Tandon, Chelacaropsis new genus, Chel-
etoids Ouclemans, Cheletogenes Oudemans, Cheletomimus Oudemans,
Cheletomorpha Oudemans, Cheletonella Womersley, Cheletophanes
Oudemans, Cheletophyes Oudemans, Cheletopsis Oudemans, Cheleto-
soina Oudemans, Chelonotus Berlese, Cheyletia Haller, Cheyletiella
Canestrini, Cheyletus Latreille, Eucheyla Berlese, Eucheyletia new
genus, Eutogenes new genus, and Neocheyletiella new genus.
The Cheyletidae are prostigmatic mites with short styletlike
chelicerae; with a short palpal tarsus located on the posterior part
of the palpal tibia rather than on tip and in most cases bearing
comblike and sicklelike setae; palpal tibia with a strong claw which
810275—49 1 267
268 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 99
extends beyond the palpal tarsus ; with none, one, or more plates on
the dorsum of the body; and with the palpi large and pincerlike.
These mites as a whole are free-living predators, although some are
to be found in rabbit fur, squirrel fur, bird feathers, on cats, etc.
The free-living forms are found associated with infestations of acarid
mites (Acaridae), eriophyid mites (Eriophyidae), and scale insects
(Coccoidea), but as yet they do not appear to be of great importance
in controlling mites or insects. Carter et al. (Carter, H. F., Wedd,
G., and D'Abrera, V., Indian Med. Gaz., vol. 79, No. 4, pp. 163-1G8,
1944) report finding numerous mites in the sputum of patients suf-
fering from lung disorders, among these being a Cheyletus sp. Habits
of each species are listed in the main body of this report. Because
of their free-living habits the distribution of many of these mites is
world-wide.
Since several of the genera are established on the number of dorsal
plates, confusion may arise because some of the nymphal forms have
two or more dorsal posterior plates instead of one. For example, the
n3^mph of Cheletofhyes haivaliensis, new species, possesses two dorsal
posterior plates, the nymph of Cheyletus cacahuamilpensis, new spe-
cies, possesses four dorsal posterior plates, and Oudemans (1921) in
discussing the generic status of GheJetomwms states that the nymjph
of €heyletia squamosa (Degeer) has two dorsal posterior plates.
Adults of CheJetoneJJa and Gheleto'psis have only the single dorsal
anterior plate; adults and nymphs of Cheletonmnus have a single
anterior plate and two posterior plates ; and adults of the other genera
have the usual anterior and posterior plates.
The descriptions are based on material mounted on slides in balsam,
modified Berlese fluid, or polyvinyl alcohol (PVA) , and in most cases
the material has been flattened to some degree. The so-called balloon
setae of certain mites have been seen only on specimens which have
been mounted, and have been drawn as seen. The exact nature of these
setae on living mites is not known. Certain other types of setae pre-
sent the same problem.
Only species in the National Museum Collection have been de-
scribed and figured. The other species are placed in the keys and are
listed in the text.
Since Oudemans monographed the family in 1906, only a selected
bibliography of publications prior to that date is given, but references
to all important taxonomical publications since then are listed. Vitz-
thum (Die Tierwelt Mitteleuropas, vol. 3, No. 3, pp. 54-56, 1929)
gives keys to the European species, and Rodendorf (Wiss. Ber. Mos-
kauer Staats Univ. Zool., vol. 42, pp. 69-98, 1940) gives keys to the
Russian species.
Types of new species, unless otherwise stated, are deposited in the
United States National Museum.

MITES OF FAMILY CHEYLETIDAE — BAKER 271
The foregoing description was taken from mites collected on rabbits
at Albany, K Y., May 7, 1942, by R. D. Glasgow.
This is a well-lmown species which appears to be universally dis-
tributed on rabbits. It has been stated that it preys on species of
Listrophorus, Psorergates, Myobia, and Notoedtms which inhabit the
fur. Pillars (1925) states that he found this mite causing lesions on
a rabbit, and also mentions a mange of man attributed to this species.
Vail and Agustson (1943) report lesions being found on a rabbit
infested with this mite. Cooper (1946) , in a review of the literature
on the mite, states that he can find no satisfactory evidence that
Cheyletiella parasitivorax attacks its mammalian hosts or causes mange
in rabbits and man. Hirst (1917) , Pillars (1925) , and Cooper ( 1946)
report finding this species on cat. Cooper (1946) also discusses the
synonymy of Ewingella americana Vail and Augustson with
CheyletielJa parasitivorax (Megnin) .
H. E. Ewing (Illinois Univ. Studies, vol. 3, No. 6, p. 77, pi. 3, fig. 15,
1909) described a mite as Cheyletiella americana. Examination of
the type reveals that the original placement is incorrect; it belongs
to the genus Pseudocheylus in the family Pseudocheylidae.
NEOCHEYLETIELLA, new genus
Palpal tarsus without comblike setae ; all tarsi with claws. With
at least a rudimentary dorsal shield.
Type, Neocheyletiella rohweri^ new species.
This genus has been erected to include the species formerly placed
with Cheyletiella which possess claws on tarsus I. Biologically this
group differs from Cheyletiella in being found on birds rather than
on rabbits or cats.

Female. — Anterior shield covering most of propodosoma, with a
pair of long setae in the posterior marginal corners ; five pairs of long
marginal setae on propodosoma; all setae about length of propodo-
soma. Posterior shield covering most of hysterosoma, posterior mar-
gin of shield concave and with a short seta in each corner as figured ;
a pair of long shoulder setae, and two pairs of long posterior setae on
abdomen, all as long as propodosomal setae. Tarsi I and II with
dorsal protuberance. Length 253jLt; width 167/*.
Type Ao5^.— "Bluebird."
Type locality. — Guelph, Ontario, Canada.
This species is similar to Neocheyletiella heteropalpus (Megnin) in
having the tarsal protuberances, but it differs in having two dorsal
shields and extremely long dorsal setae; it differs from N. pinguis
(Berlese) in having the long propodosomal setae and in having two
pairs of long posterior setae rather than one long and one short pair.
The above description was taken from the type which is in the Museum
of Comparative Zoology, Cambridge, Mass.

NEOCHEYLETIELLA SMALLWOODAE, new species
Pi^vTE 6, Figures 6-9
Female. — This species is broad, rounded, with small rostrum and
palpi. Palpal setae long, the palpal femur and genual setae serrate,
and the tibial and ventral setae appear simple ; claw small and simple.
Peritreme composed of 10 rather large segments. Propodosomal
shield small, longer than wide, angularly pyriform with a pair of
anterolateral setae; two pairs of anteromarginal setae and three pairs
of shoulder setae ; all propodosomal setae appear finely serrate. Hys-
terosoma with three pairs of anterior setae, the outer two pairs long
and distinctly serrate, the inner pair short and appearing slightly
serrate; two pairs of simple dorsal setae around anal opening; three
pairs of longer setae on posterior margin of body, the anteromarginal
pair serrate, the other two pairs simple. Legs short; leg I about
155/x long; leg IV about same length and reaches to posterior edge
of body. Tarsus I as figured, distinctive in having a strong dorsal
anterior protuberance with heavy spines. Tibia I with a minute rod-
like sensory seta. Length of body 455ju,, including rostrum 546/1, ; width
323/i.
Male. — ^In general similar to female. Propodosomal setae arranged
as in female, but as far as can be determined the shield setae are simple,
and the pair of inner shoulder setae appear to be simple. Hystero-
soma with few setae, a single pair of long serrate anteromarginal setae ;
genital opening dorsal and in center of hysterosoma, the genital plates
with three pairs of short simple setae, and anterior and lateral to the
genital opening are three pairs of short setae as figured, only the outer
pair appearing slightly serrate. Leg I not reaching to tip of rostrum ;
leg IV reaching past posterior margin of body. Length of body 300/i,
including rostrum 366/i, ; width 260/x.

The type female, two paratype females, and one male were collected
by C. Rohwer, December 5, 1939. Another female was collected from
robin at Fort Dupont, Del., April 13, 1933, by H. S. Peters.
This mite differs from N eocheyletiella heteropalpus (Megnin) as
figured, in that Megnin's species possesses much long body setae, ex-
cept for the two anterior propodosomatic pair which are extremely
short in the female.

Cheyletus malaccensis resembles closely G. rapax Oudemans, and
the differences between them may prove to be a variation within a
single species. The fact that there appear to be five pairs of setae on
the hysterosomal shield strengthens this belief.

The mite was first named and figured by Banks in 1904 and described
in 1906. In his 1906 description Banks stated that the mites were
collected from grapevine scale {Asjndiotus uvae) by Professor Web-
ster at Lafayette, Ind., in December. However, in checking over the
original notes made by Pergande it was found that the mites were sent
in by Miss Murtfeldt from Kirkwood, Mo., in December 1888, from
grapevine scale. These mites were of both sexes. Other specimens
examined were Swing's type, male, which was taken under log, Ur-
bana. 111., July 1, 1908, by H. E. Ewing; male and female specimens
on slide without data; males from gall on sycamore branches, Jack-
sonville, 111., March 1926 ; a female collected in rice straw from India
by Lennox and Rosanoff at New York, December 15, 1944 ; and a male
and a nymph collected in 1947 at Mount Holyoke College, South
Hadley, Mass., by Alice Deardorff.

T'y^^e.— U.S.N.M. No. 1771.
The female type was collected from navel orange, Azores, inter-
cepted at Philadelphia, Pa., February 9, 1945, by A. B. Wells, for
whom the mite is named. Other specimens were collected as follows:
On Eibiscm leaf, Mexico, at Hidalgo, Tex., May 1, 1936, by F. E.
Swan and A. L. Williamson; on Saccharum, oiflcinarum^ Mayagiiez,
Puerto Kico, April 29, 1912, by H. K. Plank; on Ananas sp., Canal
Zone, at Hawaii, July 16, 1936, by Uyeda; on Lantana camara., St.
Augustine, Trinidad, British West Indies, May 28, 1937, by R. G.
Fennah; on pineapple leaf, Cuba, at New York, May 18, 1936, by
MITES OF FALIILY CHEYLETIDAE — BAKER 301
Woodbury; on pineapple leaves, Jamaica, at Portland, Oreg., June
8, 1936, by L. M. Scott ; and free-living in Takabannare Shima, an
island off Okinawa, June 17, 1945, by A. B. Hardcastle.
These mites show variation in the number of dorsomedian pro-
podosomal setae. This variation ranges from one pair in the Okinawa
specimen to five pairs in the type specimen. However, of two speci-
mens from Puerto Kico, one has one pair of setae and the other has
tAvo pairs, and of the two specimens from Mexico, one has three pairs
and the other has four pairs of setae.
The species is distinctive in the number of palpal claw teeth, and
in the type of the setae. The specimen from Jamaica possesses dorsal
propodosomal setae which are normally squamiform, not staghorn-
like. This would indicate that the staghornlike structure is an arti-
fact, probably due to mounting technique. This may be true of the
other types of setae found.

Female. — Medium-sized mite, somewhat elongated, with narrow
rostrum. Femur of palpus II/2 times as long as wide, with a dorsal,
slightly broadened serrate seta and 2 simple ventral setae, the lateral
seta missing; genu with a simple dorsal seta on posterior margin;
palpal claw with 6 basal teeth ; outer comb broad, with 12 teeth ; inner
comb about one-half as long as outer comb, with about 9 small teeth.
Rostrum widening toward rear ; rostral shield outline indistinct, with
a pattern of longitudinally lined areoli; peritreme simple, composed
of long slender segments. Propodosomatic shield rounded, narrowing
toward rear, with a single pair of eyes, and five pairs of squamiform
serrate marginal setae ; inside shoulder setae is another pair of setae.
Hj^sterosomal shield in center of hysterosoma, rounded anteriorly, and
slightly pointed toward rear, with two pairs of marginal setae; six
other pairs of dorsal setae on body off shield as figured. Both shields
with areoli. Anal and genital setae simple. Legs short, I and IV
166/t long. Tarsus I, 45/a long; tibia I, 37ja long; tarsus similar to
that of Cheletogenes oaklandia., but sensory seta shorter, guard seta
simple, short; tibia with rodlike sensory seta and four simple setae of
medium length. Length of body 320/*, including rostrum 413ju, ; width
200/A.
Type hahitat. — On lemon fruits.
Type locality. — Santa Paula, Calif.
Type.—V.^.'^.U. No. 1774.
The type was collected under the button of a lemon fruit, February
23, 1939, by E. W. Baker; paratype with same data but collected
March 25, 1939. Anotlier paratype collected on same host and locality
October 29, 1938, by W. E. Buckner.
The shields, mouth parts, and tarsal-tibial setal arrangements are
distinctive. The tibia I setae are simple, rather than narrowly clavate
as in Cheletogenes quadrisetosus Berlese.

A NEW SPECIES OF COPEPOD OF THE GENUS
CORYCAEUS FROM THE NORTH AMERICAN COAST
By Mildred Stratton Wilson
Plankton collections from two coastal areas of North America,
sent to the United States National Museum for identification, have
been found to contain an unknown species of the cyclopoid copepod
genus Corycaeus. These collections were recently made at Beaufort
Inlet, North Carolina, by William H. Sutcliffe, Jr., and in the Gulf of
Mexico by Joel W. Hedgpeth. In addition, examination of a single
female from the Chesapeake Bay area, reported by C. B. Wilson
(1932) as Corycaeus lubhockii Giesbrecht, shows that it also is refer-
able to this species.

Diagnosis. — Possessing these characters of the subgenus Ditricho-
cori/caeus M. Dalil: Constituent of coastal plankton; small size;
rounded ventral process; leg 4 with its endopod bearing 2 setae, and its
second basal segment with a small protuberance inside ; spine of basal
segment of second antenna of female three times longer than that of
the second segment, only slightly longer in the male. Distinguished
by: Well-defined fourth thoracic segment; both sexes having the
genital segment approximately twice the length of the anal, with the
caudal rami divergent and longer than the abdomen in the female,
iibout three-fourths of its length in the male ; genital segment of female
inflated dorsally, that of both sexes with a medial ventral hook;
exopod of leg 4 having long spines on segments 1 and 3.
DescrljHion. — Female (pi. 18, figs. 1, 2) : Total length about 1.10-
1.18 mm. Eyes small, Metasome composing 70 percent of the total
length of the body. Cephalic segment more or less distinctly sepa-
rated from thorax, equaling almost half of the total length of the
metasome. First thoracic segment overlying the second a consider-
able amount; the latter with a lateral hyaline flange ending in a
pointed tip. Wing of third segment broad, acutely pointed, reaching
just beyond the middle of the genital segment in dorsal view, inside
margin with a spinous point near the middle. Fourth thoracic seg-
ment entirely demarcated from third, wing with a rather large spinous
tip. Fifth segment hardly visible dorsally.
Urosome composing 30 percent of total length of body. Genital
segment about twice the length of the anal, caudal rami longer than
both segments combined; proportional length of segments, lateral
view, ventral side: approximately 22:11:44. Genital segment (pi.
18, fig. 4) considerably inflated dorsally; distal margin with a fringe
of small spinules ventrally ; medial ventral hook small ; genital open-
ing witli a long plumose seta, reaching just beyond the end of the anal
segment. Caudal rami considerably divergent; with a lateral seta
distally and a terminal row of spinules; caudal setae 3 (pi. 18, fig. 3),
none as long as the ramus, the shortest spiniform, toothed on one
margin ; the others slender setae, of which the inner is the longer.
First antenna having the first two segments broad, the others
slenderer; the fourth segment the longest, the terminal the shortest.
Segment 1 with two short setae. Second segment with eight setae,
two of which are as long as the segment is wide, and four of which

ment with one long stalked seta and a pedicel bearing two short ones.
Fifth segment with a long seta distad on each side, that of the
outer side accompanied by a much shorter one. Terminal seg-
ment with one short lateral, two long subterminal, and two long
terminal setae.
Second antenna (pi. 18, fig. 7) having the basal segment about half
the length of the second, its spine about one-fifth longer than the
second segment, minutely serrate. The second segment half as wide
as long ; with a small lobe at its inside basal margin ; its spine on a
short pedicel, also minutely serrate on inner margin ; inflated lamella-
like inner portion with a stout, outer spinous process and a more
rounded projection inside. Seta like processes of third segment ob-
liquely truncated at ends, each bearing a minute hair subterminally ;
accessory claw stout, but not reaching to end of segment, three-fifths of
the length of the terminal claw, a very small spinous process at its base.
Terminal claw only slightly shorter than the spine of second segment,
and a little shorter than the third segment.
Terminal inside spines of exopods of legs 1-3 comparatively
straight ; that of leg 1 set at a very slight angle and having two foliate
structures between it and the shorter outside spine ; setae shorter than
the terminal inside spine. Terminal spine of exopod of second leg
(pi. 18, fig. 6) hardly curved, inside margin with long, fine hairs;
serrate outer flange not reaching to distal end and not continued across
the spine to inner edge ; terminal seta a little longer than the spine.
Terminal spine of exopod of third leg very straight, longer than the
third segment, proportions of spine to segment about 11:8; inside
setae reaching a little beyond the spine.
Leg 4 (pi. 18, fig. 5) with the exopod approximately as long as the
second basipod segment is wide. Top of second basal segment with
a small central hump, set marginally with fine hairs ; inside protuber-
ance a comparatively large, well-rounded lobe. Segment 1 of exopod
very narrow and long, about three-fourths as long as segments 2 and
3 combined; proportional lengths of segments, outer edge: approxi-
mately 27 : 15 : 20. Spines of segments 1 and 3 long, nearly equal to
one another, that of segment 1 reaching at least to the distal end of
the second segment. The five inner setae of the third segment all
laterally placed, the sixth much broader at the base, in a terminal
position, the apex and seta indistinctly demarcated from the rest of
the segment (pi. 18, fig. 5, a). (The figures of M. Dahl, 1912, show
variation from this usual pattern in a few species of Ditnchocory-
caeus.)
Male (pi. 18, figs. 12, 13) : Total length 0.93 to 1.0 mm., Propor-
tions of metasome to urosome approximately 73 : 27. Division of
cephalic and first thoracic segments more or less discernible. First
324 PROCEEDINGS OF THE NATIONAL MUSEUM vol.99
thoracic segment overlying second as in female. Second thoracic
segment -with the lateral hyaline flange having larger tips than in the
female. Wing of third segment reaching to abont the middle of the
genital segment, inside margin rounded at the center, without a spin-
ous point as in the female; fourth segment separated dorsally, the
distal processes usually extending a little beyond the basis of the
abdomen, tipped with short spines. Fifth segment somewhat visible
dorsally. Eyes larger than those of female.
Urosome very slender; proportions of genital and anal segments 2
to 1 as in female, but segments relatively longer and the caudal rami
relatively shorter; approximate proportions, lateral view, ventral side :
26: 13:30. Ventral hook of genital segment large (pi. 18, fig. 11) ;
lobed genital flaps with two rows of fine hairs on the surface, the
seta long, nonplumose, accompanied inside by a stout median spine
and a short process with a broadened base (pi. 18, fig. 10). Caudal
rami about three-fourths the length of the abdomen, with a short
lateral seta distally; terminal setae 3 (pi. 18, fig. 14), the inner the
longest, stout and spiniform, equaling the ramus in length and adding
to the superficial appearance of great length of the urosome; the
outer also spiniform, about one-fourth as long as the inner ; the third
slightly longer, slender and sinuous, placed subterminally near the
dorsal inner edge.
Second antenna (pi. 18, fig. 8) with the basal segment about half the
length of the second; its spine finely serrate and about as long as
the second segment. Lamina on inner margin of second segment
with a stout outer spinous process, the central portion of the lamina
very thin, but produced into a second spinous projection ; surface of
segment near middle with a row of minute teeth, hardly visible except
at high magnification ; spine with stout barbules which are most thickly
set in the central portion. Third segment with the basal process very
slender, its tip divided, reaching about to the end of the segment.
Accessory claw stout basally, otherwise very slender, reaching by al-
most half its own length beyond the base of the terminal claw; its
tip also divided; a secondary spine, with a 3-pronged apex, at its
base. Terminal claw stout, blunt ended, slightly exceeding in length
the two basal segments combined.
Exopod of first leg (pi. 18, fig. 9) having the distal part of the
terminal inside spine a little recurved, but the whole directed in-
ward, the apex of the segment being incised centrally for a short
distance, the resulting two portions having each a hyaline, foliate
structure inside; this whole condition suggested in the female, but
much more strongly developed in the male. The hyaline flanges of
the outer margin of the segment minutely serrate; that of the distal
portion rather short due to the excessive development of the distal
A NEW SPECIES OF CORYCAEUS — WILSON 325
spinous process. Setae short, not reaching to the distal end of the
terminal inside spine.
Leg 4 like that of the female, except that the inside protuberance
of the second basal segment is not quite so large, the outer margin
lacks the setose hump, and the first exopod segment is wider, with its
spine reaching a little beyond the distal end of the second segment.
Remarks. — This species occurred in the Beaufort and Gulf of
Mexico collections with Gorycaeus amazonicus F. Dahl. The two are
apparently the chief representatives of the subgenus Ditrichocory-
caeus on the American Atlantic coast. C. amazonicus was originally
described from near the mouth of the Amazon River, and M. Dahl
(1912) has reported it farther south along the Brazilian coast and
from the coastal waters of the Tortugas and Bermuda Islands.
Gorycaeus lubbockii Giesbrecht, with which C. B. Wilson confused
G. americanus, has been shown by M. Dahl (1912) and Gumey (1927)
to be an Indo-Pacific form of the subgenus.
G. amoBonicus and G. ainericajius are similar in size and in certain
distinguishing characters of the appendages. They are the only
species of the subgenus having the terminal portion of the exopod of
the male first leg incised, and the inside spine thus set somewhat at an
angle; this is most pronounced in amazonicus. Likewise, they alone
have the spines of the first and third segments of the exopod of the
fourth leg so elongate. In the male of G. amazonicus, this condition
is apparently somewhat variable, some specimens examined having
the spine of the first segment reaching well beyond the middle of the
third segment. The arrangement of the setae of the third segment of
the fourth leg is also similar in the two species, but they differ in
having the protuberance of the second basal segment scarcely developed
in G. amazonicus, and in the relative proportions of the segments of
the exopod — in G. amazonicus the second and third segments are
subequal.
Both females of the two species have the genital segment inflated
dorsally but are easily distinguished from one another by the relative
proportions of the abdominal segments and caudal rami. The genital
and anal segments of G. amazonicus are approximately equal (the anal
only a little longer in lateral view), and the caudal rami are only
slightly longer than the anal segment. In addition, the wings of the
third thoracic segment are exceptionally long, reaching to the distal
end of the genital segment. In the male of G. amazonicus, the anal
segment is about two-thirds the length of the genital, and the caudal
rami are slightly longer than the anal segment.
The proportions of the two segments of the abdomen of Gorycaeus
americanus approach most closely those of the females of G. africanus
F. Dahl and G. farrani Fruchtl. Both of these species are also dis-

tinguished by having long caudal rami; in each instance, however,
they do not attain the length of the abdomen. Corycaeus ameri-
cantis differs not only from these species, but from all other species
of the subgenus known to me, in having the caudal rami of the female
longer than the two abdominal segments combined.

THE PIMA COUNTY (AKIZONA) METEORITE
By E. P. Henderson and Stuart H. Perry
Tlie name Pima County is provisionally given to a small but most
unusual iron meteorite acquired by Stuart H. Perry in 1947 from Prof.
Eldred G. Wilson, of the University of Arizona at Tucson. Its history
is unknown except that it was brought to the university many years ago
by someone who is supposed to have found it in the vicinity of Tucson,
Pima County, Ariz.
The specimen, which has been given to the United States National
Museum by Mr. Perry, weighed only 210 grams. It is pyramidal in
shape, the base, which apparently was the evenest of the four sides,
having been partly polished. Standing on that surface, the pyramid
is about 11/2 inches high and 1% by 1% inches in the other two direc-
tions. Though the polished surface did not seem to have been sawed,
but only partly rubbed down, this iron may have been part of a larger
mass. If so, the larger mass is unknown, and the authors know of no
other nickel-poor ataxite having the same microstructure.
The most striking feature of this iron is the remarkable flow struc-
ture developed on three of its pyramidal sides, consisting of deep fur-
rows and ridges which cover the surface and curve around one of the
edges between them. The fourth side is not furrowed and ridged but
shows some minute droplets of melted metal. The fused metal in
these flight markings shows minute pores formed by bubbles during
the time the iron was molten.
The microstructure of the Pima County meteorite is that of a nickel-
poor ataxite, consisting of kamacite with a profuse dispersion of min-
ute particles of schreibersite. Generally grain boundaries are not
818711 — 49 353

iPROCEEDINGS OF THE NATIONAL MUSEUM
apparent, though in places there are faint remnant gamma boundaries
along which phosphide particles are disposed.
At numerous points the phosphide particles are thickly crowded
in round areas, which appear to the eye as dim lighter spots on the
etched surface and at moderate magnification suggest galaxies in a
photograph of the stars. At high magnification the phosphide par-
ticles appear irregular in shape, fairly uniform in size, and without
orientation. In places these groups or "galaxies" of phosphide par-
ticles inclose small irregular black inclusions of unusual character —
a dense aggregate of phosphide particles in a phosphide-poor ground-
mass. At low magnification they resemble areas of black gamma-
alpha aggregate, but they are definitely proved to be phosphide.
On a thin slice cut from the base of the jDyramidal mass the specific
gravity was determined and a chemical analysis made, after all fused
material from the outer edge of the slice had been removed. The
sample was placed in a flask and covered with dilute hydrochloric
acid, and the gas given off was passed through a train of lead-acetate
solution to precip)itate any sulphide gas as lead sulphide. There was a
small residue in the flask after it had stood in contact with the acid
for 20 hours. This insoluble material was filtered off and washed
several times with dilute hydrochloric acid to make certain that it
was free from kamacite. The residue was then taken up in aqua
regia, diluted to volume, and analyzed separately from the portion
soluble in hydrochloric acid.
The weight of the material soluble in hydrochloric acid and called
kamacite, and that of the material insoluble in hydrochloric acid and

THE PIMA COUNTY METEORITE — HENDERSON AND PERRY 355
called schreibersite, are both unknown. The results of the determi-
nations in both portions were used to calculate the percentage of the
elements present in each portion. The analysis reported for the mete-
orite was obtained by combining the analyses of schreibersite and
kamacite.
This schreibersite is unusually high in cobalt, considerably above
any other analysis of this mineral found in the literature. Since the
analysis was made by dissolving the residue, which was insoluble in
hydrochloric acid, in aqua regia and dividing the solution into ali-
quot parts, there was no chance for any check determinations. The
authors have no reason, however, to question the results. The ratio
between FeNiCo and P is 3.02 to 1 and is consistent with the theoreti-
cal ratio for this mineral. The general composition of this iron is
in close agreement with other nickel-poor ataxites.
The only other nickel-poor ataxite known from Arizona is the
Navajo iron, which is now in the Chicago Natural History Museum.
Unfortunately, that important specimen has never been studied, and
the only published information as to its composition is a short note by
George P. Merrill ^ in which its type was announced and a statement
made that the nickel content was 5.81 percent.
The Pima County iron, though of unknown origin, will be consid-
ered a separate and distinct meteorite unless otherwise proved from
later information.

THE LINWOOD (NEBRASKA) METEORITE
By E. P. Henderson and Stuaet H. Perry
The meteorite here described was discovered in 1940 or 1941 on
the farm of Joseph W. Vrana, 1% miles south and I14 miles west of
Linwood, Butler County, Nebr., in section 3, township 16, range 4
(latitude 41°26' N., longitude 96°58' W.) . It was found buried about
7 or 8 inches beneath the surface of the soil while Mr. Vrana was
operating a disk harrow.
The meteorite as received by Mr. Perry weighed 46,000 grams and
was presented to the United States National Museum intact except
for a 1- or 2-ounce fragment removed from one end. The dimensions
are approximately 12 by 11 by 5 inches. The surface is evenly cov-
ered with iron oxide, and there are no remaining structures of flight
markings or original crust. It is definitely not a recent fall. There
are many "thumb marks" of varying size on the surface but no unusual
features worthy of special note.
The Linwood iron is a coarsest octahedrite with many silicate in-
clusions (pi. 21, fig. 1) . The octahedral pattern is irregular and quite
different from the coarse octahedrites of almost identical composition.
The kamacite bands are mostly short and vary in wadth from 2 to 4
nun. or a little more, but in some places polyhedral masses nearly
half an inch across are found. The kamacite shows abundant Neu-
mann lines. The individual kamacite areas are not granulated as
they would be if there had been reheating followed by quick cooling,
yet the general structure of the octahedral pattern gives the impres-
818712—49 357

sion of being granulated. No taenite lamellae or plessite is visible,
though the microstriicture shows occasional minute atypical plessite
fields with a diversity of structure (pi. 21, fig. 2; pi. 22, figs. 1, 2) and
occasional small schreibersite bodies. A few small thin scales believed
to be taenite were found attached to the kamacite when the silicate
inclusions were broken out for study. No rhabdites were observed.
There are veinlets of silicates separating some of the kamacite areas,
and in several cases these extend from one silicate area to another,
but always around the edges of a kamacite boundary.
The most distinctive feature of this meteorite is the silicate in-
clusions. These are numerous, colored black wnth carbon, and of
irregular shapes, usually elongated or sprangling, with dimensions
up to 2 inches or more. The bodies of the inclusions in many places
extend into the octahedral structure as black irregular veins or lines,
often of considerable length, and resemble cracks invaded by iron
hydroxide. Actually little hydroxide is present except around the
edges of the slice close to the outer surface. Occasional particles
of silicates are found in the kamacite inclosed in the silicate areas.
The structure of the iron indicates that the inclusions segregated be-
fore the octahedral structure was fully established. There are, how-
ever, some small rounded or irregular-shaped masses of iron appar-
ently isolated within the silicate areas. Although these appear, in
the section cut, to be islands of iron, they may be little tongues of
metal projecting into the silicate areas from the underside of the
inclusion.
To provide a sample for study a slice was cut and etched, and from
this slice areas of iron were selected which were free from inclusions.
Likewise, portions rich in silicates were cut out to yield suitable mate-
rial for a study of these inclusions.

THE LINWOOD METEORITE — HENDERSON AND PERRY 359
The composition of the metallic portion of the Linwood meteorite
agrees very closely with that of the El Burro/ although in the latter
the kamacite bands are very broad (2-3 cm.) and fairly regular in
direction. The structure of the Murnpeowie ^ is entirely different,
consisting of rounded grains, small to moderate in size, without rec-
ognizable octahedral structure.
Qualitative chemical tests were made upon the inclusions in order
to determine their nature. Graphitic carbon is present in all the sili-
cate inclusions; troilite was positively identified by collecting the
hydrogen sulphide gas liberated when the powder was treated with
hydrochloric acid; schreibersite was recognized by its physical habit
and its strong magnetic properties. The acid extract from the sili-
cates was found to contain magnesium, calcium, iron, nickel, traces of
phosphorus, and soluble silica.
The bulk of the silicates is olivine, but there may be a small quantity
of anorthite present since the quantity of calcium found in the acid sol-
uble extract appears too large to be calcium derived from impurities
in olivine. The silicates insoluble in hydrochloric acid were washed
with dilute sodium-carbonate solution to remove the silica which had
separated by acid attack on the olivine, and then air-dried for optical
examination. Because of the complex nature of these silicates and
the difficulty of obtaining enough material to make mineral separa-
tions and chemical analysis, the authors decided that an optical study
would give results capable of more accurate interpretation.
The general character of the olivine was determined by assuming
that all the magnesium found in the acid soluble portion was derived
from olivine, combining it with the total of the acid-soluble silica and
then adding enough FeO to give the theoretical olivine ratios.

Chemically the pyroxenes are in equilibrium.
Carbon is distributed through all the inclusions but not always

Only a few schreibersite bodies were observed in these inclusions, but
they seem always to occur adjacent to the metallic iron and not as
isolated masses in the graphite and silicate material.

THE NEARCTIC SPECIES OF THE FAMILY
STEPHANIDAE (HYMENOPTERA)
By Henry Townes
The Stephanidae are a family of relatively large, elongate parasitic
Hymenoptera usually regarded as rare, but sometimes common in the
Tropics. They have a spherical head, long neck, stalked abdomen,
long hind coxa, swollen hind femur, and long ovipositor: characters
that together give an appearance unlike any other insects except
certain groups of Braconidae. In these features (except the oviposi-
tor length) the primitive genus Schlettererius is conservative, and
the more specialized genera progressively more extreme.
The family may be at once distinguished by habitus (pi. 25, figs. 1,
2) and the crown of five blunt to acute teeth surrounding the median
ocellus of all species. The multisegmented antenna, the wing vena-
tion, and other structural features suggest close relation to the Brac-
onidae. The crown of teeth on the head, shape of the mandible,
venation, and some other features are reminiscent of the Orussidae.
Stephanids are often collected on dead tree trunks. Because of
this and their habitus, the species are generally presumed to be para-
sites of wood-boring Coleoptera. Other possible hosts are aculeate
Hymenoptera nesting in wood. The only known rearing record is of
a short series of Diastephmms leueostictus in the United States Na-
tional Museum, from Agrihis kalshoveni in Java. The adults are
sluggish and awkward in walking and slow in flight.
Two genera containing six species are known from America north
of Mexico. The types of the described species have been studied,
except for these of the names Stephanus Hcoloi" Westwood and S.
sickmanni Schletterer. Most of the specimens studied are in the

Stephanus cinctipes Cresson. Monobasic.
The free first abdominal sternite and exceptionally complete vena-
tion mark this genus as the most primitive of the family. The 5-seg-
mented hind tarsus of the female, three teeth on the under side of
the hind femur, and several venational features indicate rather close
relation to Stephanus^ a monotypic genus of Europe.
Schlettererius contains only the species below. Stephanus ruflpes
Say has been referred to Schletterenus^ but it belongs in the Bracon-
idae, as evidenced by the following characters in Say's description:
Abdomen sessile, the petiole not visible; thorax not remarkably
attenuate before ; propodeum with two slightly elevated, longitudinal,
distant lines; stigma large, triangular, and fuscous; length 5 mm.
Say placed the species in Stephanus largely on similarity of wing
venation with Jurine's figure of Stephanus serrator. It has never
been correctly identified since it was first described.

Megischus is a pantropic genus containing about 60 described spe-
cies, but at least 20 of these appear to be synonyms. Most of the
species now stand in literature under the generic name Stephamis.
Megischus differs most conspicuously from Stephanus and Schletter-
erius in having only three segments in the female hind tarsus, and from
all other genera in the family in its more complete venation.
Five Nearctic species are included, divisible into three species groups
as indicated in the key to species.

scribed by Viereck (Trans. Kansas Acad. Sci., vol. 19, p. 325, 1905)
as Stephanus acutns of Lepeletier and Serville. The true '"'' Stephanus'''
acutus is a Neotropical species.
Adults are on the wing through the summer and are most com-
monly taken in July and August. Some early and late dates of col-
lection are April 25 at Dallas, Tex., June 6 at Plummers Island, Md.,
and September 10 at Cape Henry, Va. An adult was reared from
Quercus hicolor at Hummelstown, Pa., by J. N. Knull, and one taken
on dead Populus grandidentata at Ithaca, N. Y., by W. W. Middle-
kauff. I took a short series on a standing dead beech {Facfus grandi-
folia) at Takoma Park, Md. The tree had been dead about 4 years,
and the bark was beginning to fall off but most of it still adhered
tight l3^ On the bark of the trunk the stephanid looked much like a
Xorides (Ichneumonidae) , but one male and one female were seen
with the head and fore part of the thorax raised high from the trunk
and the hind legs spread wide apart. In the case of the female the
hind legs were closely applied to the bark. The male in this position
was cleaning its antennae. When a net was put near a specimen on
the trunk, it would walk away backward and would be slow to take
flight. Flight, walking, and other movements were all sluggish.

NINE NEW XYSTODESMID MILLIPEDS FROM VIRGINIA
AND WEST VIRGINIA, WITH RECORDS OF ESTAB-
LISHED SPECIES
By Richard L. Hoffman
The millipeds reported herein were accumulated largely through
field work by the author and by Dr. Horton H. Hobbs, Jr., during
the summer of 1947. Five of the species listed were collected near
the author's home, in Alleghany County, Va., and four species are
due to Dr. Hobbs' field work at Mountain Lake, Va., and in southern
West Virginia. The others, with a few exceptions, were obtained on
a trip through southwestern Virginia in June and July by Hubert I.
Kleinpeter and the author. Lloyd G. Carr sent a number of speci-
mens from Augusta County, and Charles M. Wilson and Miss Mar-
garet Walton have contributed a large amount of material from
Mountain Lake. Individual specimens have been donated by Dr.
L. R. Cleveland, Lewis Wright, and Miss Mary Timberlake.
Of the IG species here listed, 9 are described as new. In addition,
records of the occurrence of established species are given, wherever the
collections were able to provide new distributional stations. In con-
nection with previously described forms, it seemed pertinent to add
a citation to the original description as well as to mention the type
locality. A brief diagnosis is supplied for each genus — in some cases
quoted from the original generic description.
In previous descriptions of xystodesmids there has been no uniform-
ity about the aspects from which the male gonopods have been drawn.
I believe that com.parisons of species would be facilitated greatly if
R18888— 49 1 371
372 PROCEEDINGS OF NATIONAL MUSEUlvI vol.99
the figures were made with some deference to uniformity of position.
The drawings that accompany the following descriptions were made
to show the configuration of the left gonopocl and were made from
direct cephalic and lateral or mesial aspects after the appendage had
been removed and oriented properly.
I take pleasure in acknowledging my indebtedness to H. F. Loomis
for examining specimens and supplying information, to Lawrence M.
Carter for assistance with the drawings, and to Dr. Hobbs for many
courtesies attendant upon the work as well as for many collections.

These records constitute a very considerable extension in the known
range of adela, which heretofore has been reported only from Ithaca,
N. Y,. Doubtless it ranges southward in the Appalachians and will
be found in West Virginia, Maryland, and Pennsylvania.
It is not impossible that future studies may show adela to be a syn-
onym of A. coriacea, but for the time being it seems possible to dis-
tinguish the former on minor differences in the gonopods and pattern.
APHELORIA ANTROSTOMICOLA, new species
Plate 26, Figures 1, 2
Diagnosis. — Telopodite of male gonopod strongly recurved, form-
ing slightly more than a complete circle, bent mesiad with distal end
directed cephalically ; color black, with yellow keels and large crescent-
shaped orange spots on the posterior margins of the tergites.
Description. — A medium-sized species. Length of holotype, 38,
width, 8.8 mm.; length of allotype, 40, width, 8.5 mm. Width of
body averages 22 percent of length. Segments between fourth and
NEW XYSTODESMID MILLIPEDS — HOFFMAN 373
fifteenth of full width. Keels broad, continuing slope of dorsum,
usually slightly separated. Anterior corners of keels rounded; pos-
terior corners through twelfth segment forming right angles, there-
after becoming increasingly produced caudally. Most keels with an-
terior corners lobed cephalad. Dorsolateral edges of keels produced
into ridges, most conspicuously so on posterior segments; repugna-
torial pores dorsal in position, near middle of keel.
Collum with posterior margin relatively straight in both sexes.
Anal segment truncate distally and bearing a small terminal tuft
of setae, triangular in dorsal aspect, slightly longer than broad, its
base Avider than the distance between keels of penultimate segment.
Anal valves slightly inflated, glabrous, their mesial edges produced
into ridges, a tiny tubercule on each valve near the center of the
mesial margin, no other sculpturing. Preanal scale triangular, as
broad as long, somewhat rounded distally, with three terminal lobes
of which the median lobe is conspicuously larger than the other two,
in this respect differing from most other species.
Bases of the last pair of legs almost in contact mesially. Sternites
and coxae unarmed, femora with long spines ; legs hirsute, terminat-
ing in heavy curved claws. Coxae of the second pair of legs of the
male with the usual rounded knobs, which are truncate and flat
distally.
Gonopods typical of the genus in consisting of a somewhat enlarged
basal portion and a rounded, loosely coiled telopodite blade, which in
this species makes somewhat more than a complete circle and is bent
mesiad and then distad, as shown in the drawings. Basal spine rather
small and slightly curved, arising from a cephalolateral shoulder.
Mesial side of base with a rounded setiferous shoulder.
In life, dorsum black with caudolateral two-thirds of keels bright
yellow. A central row of large crescentic reddish-orange blotches on
posterior margins of the tergites ; in males these blotches are usually
separated from the yellow keels but in females tend to be in contact —
in which case the demarcation between the colors is a sharp one.
Head light brown, margins of labrum and antennae light brown,
sides of head and antennal sockets yellowish. Each article of an-
tennae white distall3^ Sides of body a burnished yellow, legs light
yellow, sternites tan. Anal valves yellowish, usually with a central
brown mark.
Ty'pe s'pecimens. — Holotype and female allotype in the U. S. Na-
tional Museum, No. 1802. Additional male and female topopara-
types in my personal collection. No. 6-10-17-lb.
Type locality. — Sinkhole at entrance to Stull's Cave, on property
of C. R. Stull, 8 miles southwest of Lowmoor, Alleghany County,
Va., on County Route 608. Seven specimens were collected during
374 PROCEEDINGS OF NATIONAL MUSEUM vol. s9
the course of about 10 minutes in the leaf mold accumulated in the bot-
tom and on the sides. No specimens were found in the adjacent
woods.
Remarks. — As far as color pattern goes, this species is like A. Virginia
Chamberlin from Pittsylvania County, Va., and the new species de-
scribed in this paper as A. picta from Mountain Lake, Va. However,
according to the description, Virginia has the keels orange and the
median spots yellow, a reversal of the pattern in the other two species.
The median spots of antrostomicola tend to merge into the yellow of
the keels, whereas in none of my specimens of picta does this condi-
tion obtain. Besides, the gonopod of antrostomicola^ although simi-
lar to that of ficta^ presents several differences.
The specific name of this species refers to the habitat in which the
types and only known specimens were collected.
APHELORIA ASPILA Chamberlin
Apheloria aspila Chamberlin, Bull. Univ. Utah, vol. 30, No. 2, p. 10, fig. 33, 1939
(Soco Falls, N. C).
Virginia : Grayson County : Mount Kogers, east side near top, RLH
No. &-3047-2b (one male).
Previously known only from the type locality, which is near Waynes-
ville, Haywood County, N. C. This new record extends the range
northward in the southern Blue Ridge to the Balsam Mountains. A.
aspila, like Boraria Carolina, which is also known only from Soco
Gap and Momit Rogers, may be found to be widespread in western
North Carolina.
APHELORIA CORIACEA (Koch)
Fontaria coriacea Koch, System der Myriapoden, p. 141, 1847 ("Pennsylvania").
Virginia: Albemarle County: Stony Point, RLH No. 10-3047-le
(1 male) ; Alleghany County: 2 miles northwest of Clifton Forge,
RLH No. 6-1447-la (3 males, 4 females) ; Augusta County: Sherando
Lake, near Lyndhurst, RLH No. 8-1547-lb (many males and females
collected by Carr) ; Roanoke County: Roanoke, RLH No. 7-547-1
(1 male collected by Wright).
The occurrence of this form at Clifton Forge is interesting. It
is common at and aromid a large, deserted sawmill, but only once in
many years' acquaintance with the region have I seen a specimen in a
different place. This exceptional creature was across a small ridge
from the sawmill and no more than a thousand yards away from it.
At Roanoke, where I have seen fragments of this form, it seemed
to be common, of all places, in pine woods on a dry shale monadnock.
Bleached specimens could be found under rocks and logs, and Mr.
Wright (who later secured a living specimen nearby) informed me
NEW XYSTODESMID MILLIPEDS — HOFFMAN 375
that in wet weather he had seen the millipeds crawling about in the pine
stands.
The locality at which Mr. Carr obtained a large series of speci-
mens is at the base of the Blue Ridge, in a moist hardwood forest
with many ponds and marshes.
All the specimens listed above are very large, some attaining a
length of 45 mm. The keels are bright reddish pink, and the posterior
margins of the keel are marked by broad yellow bands. ]Mr. Loomis,
upon examination of a specimen, suggested that Koch's name be used
for my material, an allocation with which I gladly concur. The male
gonopods of the specimens are identical with those of many large,
cross-banded Aphelorias from Ohio, West Virginia, and Pennsylvania.
The status of the banded Aphelorias is confused, and some hesitation
attends my identification of some of the Virginia material. A thor-
ough revision of the genus, based on adequate series of specimens, is
much to be desired.
APHELORIA KLEINPETERI, new species
Plate 26, Figures 3, 4
Diagnosis. — A medium-sized species characterized by the color pat-
tern of black dorsum and red keels and by the structure of the male
gonopods, the telopodite of which is expanded distally into a spatu-
late portion suggesting that of Sigiria,.
Description. — Length of holotype, 37, width, 7.2 mm., length of
allotype, 39.1, width, 8.1 mm. Width of body averages 20 percent of
length. Segments between fourth and fifteenth of full width. Keels
moderately broad, not overlapping. Anterior corners lobed, rounded ;
posterior corners through twelfth segment approximately right-
angled, becoming caudally produced on the posterior third of body.
Keels of segment 18 almost enclosing those of 19. All keels with dorso-
lateral edges raised, particularly so on last 10 segments; repugnatorial
pores on dorsal side of swellings.
Collum crescentic in shape, as long as the next two segments com-
bined, its posterior edge with a median emargination, ventrolateral
extremities directed slightly caudoventrad.
Anal segment triangular in dorsal aspect, longer than broad, base
slightly wider than distance between keels of penultimate segment;
end truncate, bearing a few setae. Anal valves slightly inflated, gla-
brous, their mesial edges produced into ridges each of which bears a
single setiferous papilla. Each valve with a small knob near the center,
otherwise unsculptured. Preanal scale very broadly triangular,
rounded, with one terminal and two smaller lateral lobes.
Bases of last pair of legs almost in contact mesially. No coxal or
sternal armature. Trochanter and femur with large spines. Femora
376 PROCEEDINGS OF NATIONAL MUSEUM vol.09
practically glabrous, trochanters and terminal podomeres very hirsute.
Terminal claw curved, strong. Male with coxae of second pair of
legs bearing the usual knobs, these rounded distal ly.
Gonopod with the loosely coiled blade and basal spine characteristic
of ApheloHa; distinct in the large subterminal expansion of telopo-
dite, with a small distal acumen. Blade of telopodite bent slightly
mesiad. In situ, blades lie against each other and directed at right
angles to the longitudinal axis of the body. In mesial aspect, a fur-
ther distinction can be seen in the deep sinus on the base of the telopo-
dite just behind the setiferous shoulder. Basal spine medium in size,
borne on a small cephalolateral shoulder.
In life, dorsum very dark brown or black, with outer and cephalic
margins of collum, caudolateral halves of keels, and tip of anal seg-
ment bright red. Underparts yellowish tan, legs becoming lighter
distally, claws brown. Head dark brown above, margins of labrum
light yellowish brown. Antennal sockets and first three articles yel-
low, becoming darker distally.
Type specimens. — Holotype and female allotype in the U. S. Na-
tional Museum, No. 1803. Two male paratypes in my personal col-
lection. No. 6-304T-lc. The allotype was collected by J. E. Graf
on Jmie 5, 1940, the others were taken on June 29-30, 1947, by Klein-
peter and me.
Type locality. — Burkes Garden, Tazewell County, Va. The tops
of the surrounding mountains belong to the Canadian Zone. A speci-
men (the type) was taken at 4,600 feet on Beartown Mountain, in a
very wet forest of maple-spruce-redbud association, with mesophytic
herbs such as Impatiens pallida. The paratypes were found in Mill
Gap, at 2,900 feet, in a hemlock-laurel association. The allotype was
collected on Clinch Mountain (eastern rim of Burkes Garden) at
4,300 feet.
A. kleinpeterl shows no close relationships with any other known
member of the genus. The gonopods represent, perhaps, a further
development of the pi<;ta type; but the red and black coloration is
unique for the genus.
I take pleasure in naming this handsome species for my good friend
and tireless field companion, Hubert I. Kleinpeter, who secured the
holotype as well as many other diplopods during our investigations.
APHELORIA PICTA, new species
Plate 26, Figuees 5, 6
Diagn/)sis. — A medium-sized species, characterized by the color
pattern of yellow keels and large reddish median blotches, and by
the gonopod of the male, which is very much recurved, slender, and
bent mesiad and distad, with a conspicious subterminal "heel."
NEW XYSTODESMID MILLIPEDS — HOFFMAN 377
DescHption. — Length of holotype, 41, width, 9.4 mm.; length of
allotype, 39, width, 9 mm. Width of body averages 23 percent of
length. Sides of body subparallel, segments 4 through 15 of full
width. Keels moderately broad, continuing slope of dorsum, usually
well separated. Anterior corners of keels rounded, posterior corners
also somewhat rounded, not as sharply angular as in other species.
Keels of segment 15 not produced caudally, those of 16 noticeably
produced. Dorsolateral edges of keels raised into ridges; repugna-
torial pores situated clorsally, at about middle of keel.
Collum with both cephalolateral and caudolateral margins tapering
distally.
Anal segment triangular in dorsal aspect, longer than broad, its
basal width approximately equal to distance bewteen keels of the
penultimate segment ; truncate distally, bearing a few scattered tufts
of setae. Anal valves slightly inflated, bearing a few scattered setae,
their mesial margins raised into ridges each of which bears a single
seta. Preanal scale triangular, somewhat longer than broad, with
three terminal lobes of which the median one is conspicuously larger
than the other two — in this respect agreeing with A. antrostomicola.
Bases of last pair of legs very slightly separated. Sternites and
coxae unspined. Trochanters and femora spined. Legs terminating
in a strong curved claw, with many stiff bristles around its base.
Coxae of second pair of legs of males with the usual cylindrical knobs
which in this species are flattened distally almost to the extent found
in antrostomicola.
Gonopods resembling those of antrostomicola in being almost cylin-
drical and narrowly tapering, not flattened or bladelike and in being
bent mesiad and distad in more than a complete circle; differing
from antrostomicola in the curves of the telopodite being rather angu-
lar with straight interspaces and in the subterminal "heel," which
gives the distal third of the appendage the appearance of an Oriental
slipper. Base of telopodite with a mesial setiferous shoulder and
a cephalolateral should which bears the basal spine.
Dorsum black, with caudolateral half of keels, tip of anal segment,
and legs yellow. A large, reddish-orange crescentic blotch on pos-
teromedian margin of each tergite. Collum with distal ends of dorsal
surface yellow, and a dorsomedian hourglass-shaped marking of
orange. Front of head black, margin of labrum brown. Antennae
light brown, distal portions of the articles not white. Sternites pos-
terior to gonopods tan (except last), sides of body brownish tan,
anal valves brown.
Type specimens. — Holotype and female allotype in the U. S.
National Museum, No. 1804. Additional male and female topopara-
types are in my personal collection, Nos. 6-2647-1, 7-247-lb. All
specimens collected by Hobbs, Wilson, and Walton.
378 PROCEEDINGS OF NATIONAL MUSEUM vol.99
Type locality. — Mountain Lake, Giles County, Va. Most specimens
collected near the University of Virginia Biological Station, with pre-
dominating forest cover of deciduous trees such as oak, maple, and
yellow pojjlar. The undergrowth is largely of ericaceous shrubs.
Mountain Lake is located on the top of Salt Pond Mountain, in central
Giles County, at an elevation of about 3,800 feet.
Remarks. — This species has its closest affinities with Apheloria
antrostomicola, from which it may be only subspecifically distinct.
The similarities in pattern, gonopods, preanal scale, and coxal lobes
all suggest such an association. The type localities for the two species
are less than 40 miles apart and are in the same moiuitain range.
Collecting in the intervening region will prove interesting, as it is not
yet known whether antrostomicola occurs in humus away from lime-
stone regions.
APHELORIA TRIMACULATA (Wood)
Polydesmus (Fontaria) trimaeulata Wood, Proc. Acad. Nat. Sci. Philadelphia,
vol. 6, p. 6, 1S64 (Susquehanna County, Pa.).
Virginia: Alleghany County: McGraws Gap, 3 miles northwest of
Clifton Forge, EHL Nos. 3-3047-3b, 5-1847-lb, 6-147-lb, 6-1447-lb,
and 6-2147-1; Augusta County: Sherando Lake, near Lyndhurst,
EHL No. 8-1547-lc (male and 2 females collected by Carr) ; Elliotts
Knob, 10 miles west of Staunton (1 dead female seen in August 1947) ;
Bath County : Douthat State Park, female seen June 15, 1947.
A. trimaeulata has also been reported from Mountain Lake, Va., by
Loomis (Psyche, vol. 51, p. 175, 1944). The accuracy of the locality
data, however, is not beyond suspicion, inasmuch as a summer of very
thorough collecting at Mountain Lake has not revealed any xystodes-
mids that might be considered tr'nnaculata.
The specimens listed above are all rather large, exceeding previ-
ously published measurements. Since Wood's figure of the gonopod of
trimaeulata is not very useful for comparison with specimens, it seems
advisable to relegate this large southern form tentatively to trima-
eulata until topotypic material can be examined.
A. trimnculata is a very common form near Clifton Forge, and on
damp or rainy da3''s one can observe many specimens out wandering
around. At other times no special effort is needed to dig specimens
out of the leaf mold. They are often seen on hemlock logs, but I have
yet to find one inside a log. Large numbers of unpigmented young
of this species are found during the spring months, becoming scarce
later in the year, and specimens almost mature are very rarely seen.
The change from seventh instar larvae to adults takes place during
August. Mating occurs throughout the summer, from early in June
through August.

Virginia: Grayson County: Mount Rogers, east side near top,
RLH Xo. 7-147-la (2 males).
As this species was originally described from Soco Gap Falls, near
Waynesville, Haywood County, N. C, its discovery on Mount Rogers
extends the known range considerably to the north, and suggests that
the species will be found at intervening places. Both of the speci-
mens at hand match Chamberlin's description and drawing perfectly.
Genus BRACHORIA Chamberlin

Broad short species with posterior corners of keels of segments 1
through 12 rounded instead of angular; blade of telopodite of male
