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

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 
museum catalog numbers are as follows:

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 
Nicaragua 26-26; from Florida 25-25. 

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): 

la. A continuous series of greatly enlarged spines from behind orbits along mid- 
line of back and tail to base of sting; eye about 3.5 to 4 in snout (Pacific

ICHTHYOLOGY OF VENEZUELA — SCHULTZ 27 

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-

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 CLUPEIDAE: Herrings; Sardines 

Since there were not many specimens of this family in the collections 
from Venezuela I have not made a critical study of them. The key 
to the genera of Clupeidae reported from Venezuela was extracted 
from Storey (Stanford Ichthyol. Bull., vol. 1, No. 1, p. 14, 1938). 
Those who wish to identify the species in the genus Harengula should 
consult Storey (loc. cit.), pp. 24-25.

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. 

lo. Intestine with one main loop, without numerous coils below air bladder; 
gill membranes never broadly united across the isthmus, at most only a 
narrow delicate membrane anteriorly. 
2a. Teeth in the jaws all small or minute, about equal in size. 

3a. Origin of anal fin posterior to origin of dorsal fin, very rarely almost under 
it; gill rakers long, narrow, and numerous; body compressed, except in 
young; vertebrae 37 to 46, rarely 46.

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.

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.

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.

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.

1 The counts for all but four specimens of P. athennoides were kindly furnished me by Dr. Samuel F. 
Hildebrand from his original notes accumulated during his studies of the American Engraulldae. I take 
this opportunity to express my gratitude to him for this and other help furnished.

length of head; head notably longer than greatest depth of body, 
nearly 4 times in standard length; snout bluntly rounded, projecting 
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 
anterior nostril; teeth in lower jaw variable in size, usually 18 to 24 
enlarged, the enlarged ones of upper jaw more numerous; cheek longer 
than snout and eye, about 2.3 to 2.4 in head in specimens longer than 
85 mm.; postorbital length of head 6.5 to 7.2 in standard length; gill 
rakers slender, usually 16 to 18+20 to 23 on first arch; height of dorsal 
fin about equal to postorbital length of head, its distal margin a little 
concave; distal margin of anal a little concave; first branched ray of 
pectoral fin longest, reaching to or a little past insertion of pelvics; 
pelvic fins not reaching quite halfway to anal origin; caudal fm deeply 
forked, the lower lobe a little longer and stronger than upper lobe; 
origin of dorsal fin usually equidistant between midcaudal fin base 
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 
ready for deposition, was 75 mm. in standard length and came from 
the Rio Agua Caliente. 

Named limnichthys in reference to its occurrence in a lake.

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. 

Stemopygus MiiUer and Troschel 
45. Orbital margin not free. 

5a. A cylindrical filament in a pair of grooves on under side of head in 
mental region; snout short, head chubbj^; teeth absent.

Description. — Based on the holotype and paratypes. Measure- 
ments, expressed in hundredths of the distance from snout to rear end 
of anal fin, first for the holotype, then for a paratype, in paren- 
theses, are recorded below, respectively. Total length in mm. 505

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

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.

The follow^ing number of anal rays were counted on the specimens 
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

Description. — The following description was based on the holotype 
and para types. Detailed measurements were made on the former 
and two of the latter, and these data are expressed in hundredths of 
the length to end of anal fin and recorded respectively for the holotype 
and the paratypes in parentheses. 

Total lengths 363 (221; 131.5); length to base of caudal fin 350 
(213; 128.5) ; length from tip of snout to end of anal fin 330 (202; 121).

depth of caudal peduncle 1.36 (1.24; 1,65); length of caudal peduncle 
from end of anal fin to midcaudal base 6.58 (5.60; 5.95); snout to 
occiput 13.8 (13.6; 15.7); snout to anus 8.33 (8.62; 11.7); snout to 
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.

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.

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,

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. 

4. Pseudopimelodus villosus butcheri Schultz. Gomes, Occ. Pap. Mus. Zool. 
Univ. Michigan, No. 494, p. 4, 1946 (Rfo San Juan, near Mene Grande, Venezuela). 

5. Microglanis poecilus Eigenmann. Gomes, Occ. Pap. Mus. Zool. Univ. 
Michigan, No. 494, p. 15, 1946 (Cano de Quiribana, Rfo Apure into Rfo Orinoco, 
Venezuela) . 

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. 

10. Ochmacanthvs flahelhferus Eigenmann. 1 specimen, 37 mm., East Caripito 
Creek, William Beebe, March 6, 1942. 

11. Callichthys callichthys (Linnaeus). 2 specimens, 100 and 125 mm., from 
Caripito, William Beebe, May 7, 1942. 

12. Hoplosternum thoracatum thoracatum (Cuvier and Valenciennes). 2 speci- 
mens, 67 and 77 mm., Rfo Pablo, Caripito, William Beebe, March 19, 1942. 

13. Hoplosternum littorale (Hancock). 1 specimen, 117 mm., Rfo San Pablo, 
Caripito, William Beebe, March 19, 1942. 

14. Ancistrus hrevifilis hrevifilis Eigenmann. 1 specimeUj C.N.H.M. No. 
35341, Rfo Turmero, Venezuela, Ventura Barnes, September 24, 1937.

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. 

20. Forlowella acus (Kner). 3 specimens 94 to 134 mm., from Rfo Pablo, 
Caripito, William Beebe, March 19, 1942. 

21. Spathuloricaria may represent the adult male of some species of Loricaria.

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.

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.

Figure 11. — Austrofundulus stagnalis, new species: Holotype (U.M.M.Z. No. 141918), 
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.

It is probable that Pellegrin's record for the Apure River actually 
is for another species and his material should be restudied.

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.

Lake, Trinidad, have 6 branched dorsal rays, 11 branched anal rays,

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.

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.

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).

Family POECILIIDAE 

As Dr. Carl L. Hubbs, of the Scripps Institution of Oceanography- 
had begun work on the PoeciHidae of Venezuela collected by Dr. 
F. F. Bond, he wished to work up the national collections of this 
family. Since his studies are still in progress I have omitted this 
material, along with some collected by me in Venezuela,

Family SYNGNATHIDAE: Pipefishes; Seahorses 

Earl S. Herald (1942) has prepared a key to the pipefishes of the 
western Atlantic which includes all the known American species. 
I have prepared the following key for the identification of the pipe- 
fishes reported from Venezuela, but as more collecting is done several 
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. 

2a. The keel along the middle of the side of the trunk turns downward over the 

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 

fin base Oostethus lineatu8 (Kaup) 

2b. The medial keel along side of the trunk not continuous with the lower 
lateral keel on tail.

Oostethus HtiBBS, Occ. Papers Mus. Zool. Univ. Michigan, No. 199, p. 3, 1929. 
(Genotype, Doryichthys lineatus Kaup.) 



>« 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. 



ICHTHYOLOGY OF VENEZUELA — SCHULTZ 101 

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.

104 PROCEEDESTGS OF THE NATIONAL MUSEUM vol.99 

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.

Description. — Detailed measurements were made on the holotype 
and two paratypes, and these data, expressed in hundredths of the 
standard length, are recorded in table 16. 

Greatest depth of body about 5.5 to 5.75, head 4.5 to 4%, both in 
standard length; snout 3.5 to 3.75, orbit 3)3 to 3.5, interorbital 3 to 
SYz, all in length of head; premaxillary a little curved, causing gape 
of mouth to be somewhat concave; mouth rather smaU, the maxillary 
not reaching to front of orbit; gill rakers slender, the longest about

% diameter of pupil; rear margin of pupil about in middle of length 
of head; pelvic fin insertions a little closer to upper angle of pectoral 
fin base than to anal origin; anal origin equidistant between midbase of 
caudal fin and the second third of length of opercle; first dorsal origin 
conspicuously a little in front of a line through anal origin; second 
dorsal origin about over base of sixth from last anal fin ray; pelvic 
fins short usually reaching a trifle over halfway to anal origin; the

lary processes are long, slender, with narrow bases, not triangular in 
shape; pectoral fins pointed, reaching a short distance past pelvic 
bases; interorbital space a Uttle convex, belly rounded; posterior

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.

located a very short distance in front of anal origin but much closer 
to anal origin than to base of pelvics; the body cavity and air bladder 
notably do not extend posteriorly to opposite the anal fin origin; the 
ascending premaxillary process is broadbased, and triangular in shape; 
pectoral fins pointed reaching about halfway out length of pelvics; 
interorbital space slightly convex; belly somewhat compressed, not 
fully rounded ; posterior margins of scales entire, not crenulate ; silvery 
lateral band much wider than pupU anteriorly, then partially con- 
stricted on caudal peduncle and narrower than pupil, thence a little 
wider before ending at base of caudal fin ; least depth of caudal peduncle 
not quite twice in its length; lower jaw a httler shorter than upper, 
and a little included; teeth small, in upper jaw in two rows, these 
separated by a narrow nondentigerous space, those in lower jaw in two 
rows anteriorly, becoming one row on sides; the posterior end of 
dentary scarcely elevated; a scaly sheath along base of anal fin, two 
scales wide anteriorly.

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). 

KEY TO THE GENERA AND SPECIES OF MUGILIDAE REPORTED FROM

to 179 mm. in standard length, from a fresh-water stream at Macuto, Venezuela, 
August 1-2, 1900, collected by Lj'on and Robinson. 

The following collections were made by Dr. F. F. Bond: 

2 specimens, both 61 mm., Rio Cumboto, near mouth, 2 km. northwest of 
Ocumare, May 5, 1939. 

3 specimens, 30.5 to 37 mm., Rio Guaiguaza, 3 km. west of Puerto Cabello, 
January 15, 1938. 

4 specimens, 28 to 66 mm., Rio Cumboto near Ocumare, January 5, 1938. 

1 specimen, 51.5 mm., lagoon, 3 km. west of Cumand, on road to Cumanacoa, 
March 26, 1939. 

1 specimen, 73 mm., tributary to Rio San Pedrito, 55 km. east of Barcelona, 
March 25, 1939. 



112 PROCEEDINGS OF THE NATIONAL MUSEUM vol.99 

2 specimens, 35 and 36 mm., Rio Agua Caliente at Tavorda, 6 km. west of Puerto 
Cabello, January 15, 1938. 

30 specimens, 23 to 106 mm., Rio Cerro Grande, 10 km. east of Macuto, De- 
cember 22, 1937. 

43 specimens, 22 to 43.5 mm., Rio Mamo, 15 km. west of La Guaira, November 
11, 1938. 

In the young of A. monticola, the rear end of the maxillary scarcely 
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

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

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

FiGUBE 16 

Holotype. — U.S.N.M. No. 121726, only known specimen, 08 mm. 
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.

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

in standard length. Drawn by Mrs. Aime M. Awl. 



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. 121715, 10 specimens, 33 to 50 mm., from Lago de Maracaibo 
at Yacht Club, Maracaibo, February 27, 1942. 

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.

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).

The following collections were made in Venezuela during 1942: 

U.S.N. M. No. 121658, 2 specimens, 42 and 50 mm. in standard length, Rfo 
Gudrico and tributaries between San Sebastian and San Casimiro, L. P. Schultz, 
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.

Genus AEQUIDENS Eigenmann and Bray 22 

Aequidens Eigenmann and Brat, Ann. New York Acad. Sci., vol, 7, p. 616, 1894. 
(Genotype, Acara tetramerus Heckel.) 

KEY TO THE SPECIES OF AEQUIDENS REPORTED OR EXPECTED TO OCCUR IN 

VENEZUELA 

la. Two or 2^ scales between base of first soft ray of dorsal fin and lateral line; 

the blackish lateral streak or band, if present, extending from eye through 

black lateral blotch to upper half of base of caudal fin rays; gill rakers 2 or 

3 + 5 or 6 on first arch. 

2a. Base of caudal fin rays with a prominent black spot, about one-half size of 

eye, located entirely above midaxis of caudal fin or lateral line if it 

extends on base of fin. 



" As here understood, Acara Heckel, 1840, with its t3rpe restricted by Gill to Acara crassispinis Heckcl= 
Lobotes oceltatus Agassiz, is a synonym of Astronotus Swainson, 1839, with its type, Lobotes ocellatus Agassiz, 
the only species mentioned. Thus, in Regan's revision of the South American cichlid genera, his use of 
Acara is a synonym of Aequidens.

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.

Tetrodon spengleri Bloch.) (Ref. copied.) 

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.

This species has a distribution from Florida and Gulf of Mexico 
through the West Indies to Brazil and most certainly will be taken 
off Venezuela, although so far I fail to find any record of its capture

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 
tarsi ferruginous. Head pitted, with a patch of pectinate white scales 
on the sides. Kostrum ferruginous, with the basal portion blackish, 
strongly pitted and with sparse, short, yellowish bristles laterally, the 
central area smooth. Antennae yellowish, the club paler.

with a few black, erect hairs, except along the narrow smooth median 
space; the flanks of the pro-, meso-, and metathorax thinly covered 
with pectinate white scales, the scales sparser on the mesothorax than 
on the other two segments. 

Elytra very broad, cordiform, flat to the third interstice, strongly 
declivous posteriorly, deeply pitted, and covered with long, brown- 
red hairs; two or three forked scales in postscutellar region; suture 
toward apex with a few yellowish- white setae ; elytra a short distance

beyond the middle with a series of setae in two transverse rows, 
forming a faint band from the sixth to tenth interstices. 

Posterior femora dark, thicker apically than basally, granulose, 
covered with black and white setae, the latter most numerous on the 
basal half ; armed with numerous scattered minute teeth and with three 
long, black teeth, the second slightly the longest, first and third sub- 
equal, the most distal of the three teeth placed on the interior edge, 
the other two on the exterior edge. Posterior tibiae rather broad, 
arcuate, provided with strong, erect setae on the external border, and 
long adpressed ones within. Tarsi ferruginous and covered with long 
white hairs.

Type.—V.S.l^M. No. 58186. 

One specimen, Teffe, Amazonas, Brazil, December 10, 1919. Col- 
lection Bovie through Buchanan. 

This species is most closely allied to T. guerini Monte but is smaller ; 
elytra with the interstices lower, the pits deeper, and with the pectinate 
white scales on the external margin extending across the middle ; the 
posterior femora with fewer teeth. It is smaller than T. hydropicus 
Chevrolat, a species which has the teeth on the posterior femora dif- 
ferently placed. The species is named in honor of L. L. Buchanan, 
who has taken great interest in weevils.

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. 

TACHYGONUS COMPTUS, new species 

Figure 25 

Shiny black; anterior and intermediate legs yellow, with apex of 
the tibiae usually dark and with various whitish hairs, and two fringes 
formed by curved and golden hairs, one fringe on inner edge and ex- 
tending entire length of tibiae, the other, on outer edge, short, apical 
and extending to a little above the tibial claw; all the tarsi dark with 
last segment paler. 

Head strongly pitted, sparsely so on sides, and there with small 
pectinate scales. 

Rostrum smooth, shiny and dark, slightly ferruginous at apex. An- 
tennae light yellow. 

Prothorax black, shiny, pitted, dorsal pitting smaller, flanks with 
abundant pectinate white scales. Flanks of meso- and metathorax, 
and posterior margins of abdominal segments with dense pectinate 
white scales which in some places form layers. 

Elytra black, cordiform, the white postscutellar patch well marked, 
each sutural interval with a series of white setae, the setae crossing 
in about apical half of elytra. 

Posterior femora armed with a series of numerous small tubercles 
and with four well-developed teeth, a subapical pair of which the 
inner tooth is a good deal larger than outer, a rather long submedian 
tooth, and, in line with it, a smaller one at about basal third; distad 
of the subapical pair of larger teeth are two or three small teeth on 
inner edge. Hind tibiae more or less thickened, with numerous 
tubercles on external and internal margins; white and brown hairs 
spread over femora and tibiae. Hind tarsi covered with pale hairs, 
dark, the last segment yellow. 

Length 2.1T mm. ; width 1.41 mm.

Similar to T. rugosipennis Hustache but differs by having the fem- 
ora more pointed and the femoral teeth differently placed, the scal- 
ing denser and the elytra somewhat narrower. Differs from T. scu- 
tellaris Kirsch in the pectinate scales of abdomen, by the posterior legs 
being totally black, and by the nonflattened tibiae.

also four smaller teeth, three situated between subapical pair and apex 
of tibia, the fourth based of the submedian tooth. Hind tibiae paler 
than femora, serrated on inside, curved and bearing white and dark 
hairs, tarsi with first two segments ferruginous and the last two 
yellowish, all covered with white hairs.

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.

CardiochUes nigriceps Vieeeck, Proc. U. S. Nat. Mus., vol. 43, p. 578, 1912 (female, 
male). — Chamberlin and Tenhet, Jour. Agr. Res., vol. 33, p. 21, 1926. 

Toxoneuron sp. Morgan and McDonough, U. S. Dept. Agr. Farmers' BuU. 819, 
p. 6, 1917. 

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. 

Type.—V.S.^M. No. 15007. 

In addition to the type series from Georgia and Florida, the author 
has examined specimens from South Carolina, Georgia, Florida, Vir- 
ginia, District of Columbia, Alabama, Mississippi, Louisiana, Ar- 
kansas, and Colorado. The species is commonly reared as a parasite 
of the tobacco bud worm, Heliothis virescens (Fabricius) .

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.

reference is made to C aenocheyletes franseni Oudemans, 1933. This 
is probably a manuscript name, since I have been unable to find a pub- 
lished description.

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.

Plate 6, Figures 4, 5 
Cheyleticlla canadensis Banks, Proc. Ent. Soc. Washington, vol. 11, p. 133, 1909. 

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 ;

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. 

Type host. — Leucosticte australis. 

Type locality. — Guffey, Colo. 

ry^oe.— U.S.N.M. No. 1755 . 

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.

Naturelle, Paris. 

The description was made from two specimens on one slide with 
the following data (translation, original in Japanese) : "Public Health 
Department of Formosa, Eesearch Laboratory of Medical Zoology." 
Two other specimens were collected on Gallosciurus sladeni midas 
Thomas at Myitkyina, Burma, August 6, 1945, by members of the 
United States of America Typhus Commission. 

This species is closely related to Gheyletus malaccensis Oudemans 
and may prove to be only a variety.

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.

and the description of the male was taken from a specimen collected 
in straw packing, Spain, at St. Louis, Mo., March 24, 1944 (no collec- 
tor's name given). Other United States National Museum records 
are England, France, Holland, Italy, Portugal, Australia, Java,

The species supposedly differs from C. lepidopterorum in having 
eyes located near the shield, not on it, and in having rodlike setae 
instead of the somewhat flattened ones. Possibly a synonym of O.

from Australia. It is usually found associated with scale insects or 
with eriophyid mites on which it preys, and McGregor has reported 
it predaceous on Tarsonemus haheri Ewing in California. The mite 
referred to in an article by Boyce and Korsmeier ( Journ. Econ. Ent.,

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 
reach to the apex of the appendage. Segment 3 with two stalked 
setae reaching beyond the terminus of the appendage. Fourth seg-

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

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.

erately convex above, uniformly black, with distinct greenish or 
purplish reflections in different lights, and the bottom of the punc- 
tures sometimes cupreous ; body beneath more strongly shining than 
above, greenish black, with a distinct purplish or cupreous tinge, and 
the tarsi violaceous-blue.

paratypes were collected at the type locality by F. Campos E, ; three 
paratypes were collected at the same locality during 1915 by W. F. 
Goding; and one paratype was collected in the vicinity of Piurat, 
Peru, during February 1940, by J. Soukup.

Type and paratypes.—V.S.^M. No. 58797. 

Described from three specimens ( one type) . The type was collected 
at the type locality, April 20, 1909, by F. Knab, and the two paratypes 
were collected at Punta Patuca, Honduras, April 11, 1909, by the same 
collector. 

This species is closely allied to Euplectalecia heltii (Saunders), but 
it differs from that species in being more slender, and of a brighter 
green color, and in having the last visible abdominal sternite broadly 
and transversely sinuate at the apex. The two paratypes are slightly 
more greenish on the dorsal surface than the type.

Described from two specimens (one type), collected at the type 
locality, October 24, 1918, by Harold Morrison. 

This species is allied to Mastogenius uniformis Waterhouse, but it 
differs from the description given for that species in being black, 
with a distinct purplish tinge, and in having the bases of the elytra 
bright blue and the dorsal surface of the body sparsely clothed with 
short hairs. Waterhouse, in his careful description of uniformis, does 
not mention any pubescence, and if the type was pubescent it is very 
doubtful that he had overlooked that character. Mastogenius uni- 
fomiis Waterhouse has the antennal grooves on the prosternum and 
should be placed in the genus Trigonogya Schaeffer (new combination) .

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

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.

Princeton University, to whom grateful acknowledgment is made.

"Enstatite. About two-thirds of the nonopaque insohible material 
is composed of enstatite. The enstatite grains are minute ; the crushed 
grains show distinct prismatic cleavage. Its color is gray ; colorless in 
thin fragments. Luster vitreous. Transparent to translucent. Opti- 
cally positive with a large axial angle, 2F=T5°— 78°. Dispersion 
distinct, r>v for most grains. The indices of refraction are : a= 1.659,

Chemically the pyroxenes are in equilibrium. 

Carbon is distributed through all the inclusions but not always 
uniformly within each inclusion. Troilite is usually more or less 
concentrated around the rims of inclusions, bordering the metal. 
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

KEY TO THE NEARCTIC GENERA OF STEPHANIDAE 

First nbdouiinal teriiite about 2.") as long as wide, not fused with its sternite ; 
hind wing with nervellus ; hind femur with three larger teeth beneath; hind 
tarsus of female with five segments; eighth tergite of female with a median 
apical point. (See pi. 25, fig. 1) Schlettererius 

First abdominal tergite at least 4.0 as long as wide, fused with its sternite; 
hind wing without nervellus ; hind femur with two larger teeth beneath (apical 
tooth often subdivided) ; hind tarsus of female with three segments; eighth 
tergite of female (of Nearctic species) without a median apical point. (See 
pi. 25, fig. 2) Megischus 

Genus SCHLETTERERIUS Ashmead 

Plate 25, Figure 1 

Schlettererius Ashmead, Proc. U. S. Nat. Mus., vol. 23, p. 20, 1900. Type: 
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.

Black. Second and third abdominal segments, first abdominal seg- 
ment except more or less of its base, and sometimes the fourth 
abdominal segment of male basally, ferruginous; labrum, ventro- 
lateral triangles on frons of male, basal 0.15 to 0,3 of tibiae, apices 
of front and middle femora, and a very broad subapical band on 
ovipositor sheath white; tegula brown; extreme base of wing white; 
forewing light brown beyond the basal vein, with a narrow hyaline 
band diagonally across the discal cell and across the base of the second 
discoidal cell; apical 0.5 of hind wing light brown; tarsi whitish to 
light brown, darkest apically. 

Specimens. — 9 5 , 21 2 , from Arizona (Cochise County) ; British 
Columbia (Pender Harbor, Robson, and Vancouver) ; California 
(Alta, Bass Lake, Cisco, Fallen Leaf Lake in El Dorado County, 
McCloud, Meyers, Pinecrest, Porterville, Riverton in El Dorado 
County, and Yreka) ; Idaho (Coeur d'Alene) ; Oregon (at 6,500 feet 
on Antelope Mountain in Harney County, and Ashland) ; and Wash- 
ington (Ashford, Mount Rainier, and Kooskooskie in Walla Walla 
County) . Dates of collection run from June 1 to August 29. 

This species has about the same range as Pseudotsuga taxifolki 
(Douglas fir) and seems to be most common in forests of this tree.

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.

ridge and on the inner face an almost semicircular dip; apical half 
of hind tibia swollen to about 0.7 the width of the hind femur; hind 
basitarsus 4.7 as long as wide, a little expanded apically ; first tergite 
4.5 as long as wide, polished, and with rather close cross ridges ; ovi- 
positor sheath 1.1 as long as the body.

marked with brown along the veins near the outer end of the brachial 
cell ; abdomen ferruginous basally, shading to dark ferruginous api- 
cally ; ovipositor sheath with a preapical white band. 

Paratype male : Similar to the type female but smaller (forewing 
6.5 mm. long) and with weaker sculpture and the punctures less reg- 
ularly formed. The punctures on the lower 0.5 of the temple are al- 
most obsolete, and the pair of high sharp carinae on each side of the 
front end of the pronotum are almost transverse rather than strongly 
oblique. The first tergite is 10 times as long as wide and almost

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. 

Family XYSTODESMIDAE Cook 

Xystodesiuidae Cook, Ann. New York Acad. Sci., vol. 11, p. 5, 1895. (Type genus : 
Xystodesmus Cook.) 

Genus APHELORIA Chamberlin 

Apheloria Chambebun, Can. Ent., vol. 53, p. 232, 1921. (Genotype: Fontaria

Telopodite of male gonopod a simple coiled blade, with a small 
curved basal spine. 

APHELORIA ADELA Chamberlin 

Apheloria adela Chamberun, Bull. Univ. Utah, vol. 30, No. 2, p. 10, fig. 34, 1939 
(Ithaca, N. Y.). 

Virginia: Grayson County: Mount Rogers, east side near top, 1 
male, ELH No. 7-147-2b; Tazewell County: Burkes Garden, 1 male, 
RLH No. 6-3047-lb. 

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. 



NEW XYSTODESMID MILLIPEDS — HOFFMAN 379 

Genus BORARIA Charaberlin 

Boraria Chamberon, Proc. Biol. Soc. Washington, vol. 56, p. 143, 1943. (Geno- 
type: Aporiaria Carolina Chamberlin.) 

Gonopod of male a relatively straight cylindrical process, abruptly 
tapering distally into a slender acnmen, mesial side of telopodite with 
a slender distally directed spine, 

BORARIA CAROLINA (Chamberlin) 

Aporiaria Carolina Chamberlin, Bull. Univ. Utah, vol. 30, No. 2, p. 6, fig. 10, 1939 
(Soco Falls, N. C). 

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 

Brachoria Chambeelix, Bull. Univ. T'tah. vol. .30, No. 2, p. 3, 1939. (Genotype: 
B. initialis Chamberlin.) 

Broad short species with posterior corners of keels of segments 1 
through 12 rounded instead of angular; blade of telopodite of male 
gonopod with one or two joints, basal spine on the lateral side, not ris- 
ing from a conspicious shoulder. 

BRACHORIA ETHOTELA (Chamberlin) 

Brachoria ethotela CHAiiBEKLiN, Bull. Univ. Utah, vol. 32, No. 8, p. 5, 1942 (Mar-

Virginia: Tazewell County: Burkes Garden, RLH No. 6-2947-2c 
(male and female). 

This species was described from specimens taken at Marion, in 
Smyth County ; thus the new material constitutes but a small extension 
of the range. The Burkes Garden specimens were found on Bear- 
town Mountain at an elevation of about 4,600 feet in wet deciduous 
woods. 

Genus DELTOTARIA Causey 

Deltotaria Causey. Ent. News, vol. 53, p. 165, 1942. (Genotype: DcJiotarin 
brimleii Causey. ) 

"This genus resembles Apheloria in the curvature and the length 
of the principal blade of the telopodite of the male gonopod s, but 
differs in having a thin subterminal process on the blade. It differs 
from other genera of this family in tliat the gonopods bear a large

medial pointed coxal pec: in addition to the characteristic sickle-like 
coxal spine." (Causey, op. cit.) 

DELTOTARIA CORONATA, new species 

Platk 2G, Figures 7, S 

Diagnosis. — Distinguished by the presence of three terminal proc- 
esses on the telopodite blade and by the color pattern of black on the 
back, with the keels and anterior margin of collum bright yellow. 

Description. — A somewhat longer and narrower form than the geno- 
type. Length of holotype, 36, width, 8 mm. ; length of allotype, 37.5, 
width, 8 mm. Width of body averages 21.5 percent of length.^ Keels 
of the anterior and midbody segments with the corners rounded some- 
what, those of the posterior segments with the posterior corners pro- 
duced caudally. Keels of the penultimate segment small, not 
enclosing anal segment or enclosed by those of the antepenultimate 
segment. Dorsolateral edges of all keels slightly raised into ridges. 
Repugnatorial pores dorsal in position, about at midline of keel. 

Collum slightly longer than succeeding segment, posterior margin 
rather straight in males, but tapering cephalad toward the ends in 
females. 

Anal segment triangular in dorsal aspect, longer than broad, the tip 
truncate and bearing a few setae. Anal valves glabrous, with the 
mesial margin of each produced into a ridge, not otherwise sculp- 
tured. Preanal scale broadly triangular, wider than long, with a. 
median and two lateral lobes. 

Bases of last pair of legs in contact mesial ly. Sternites very weakly 
spined, trochanters and femora strongly spined ; legs with strong termi- 
nal claws. Coxae of second pair of legs of males with prominent 
rounded knobs. 

Gonopods of male relatively large and prominent. In situ the main 
axis of the telopodite blade lies at a right angle to that of the body, 
the gonopods at rest having the blades in contact and frequently 
hooked together. The gonopod resembles that of D. brirnleii as fig- 
ured by Causey (op eit., fig. 1) in general appearance but differs in 
having three terminal teeth on the telopodite. as well as a prominent 
knob between the coxal projection and base of the blade. Coxal pro- 
jection large. 

Dorsum glossy brownish black, with caudolateral two-thirds of 
keels, anterior margin of collum, and tip of anal segment lemon- 
yellow. Underparts yellowish tan. Head dark brown, except margin 
of labrum which is light brown; antennae light brown with distal 
portion of each article white. Claws of legs brown, sternites of a 

* 27.5 percent in brimleii, according to CniiBey's mensurements. This is probably due to 
the dried and doubtless telescoped condition of the lypes.

NEW XYSTODESMID MILLIPEDS — HOFFMAN 381 

darker shade than legs. A faint dark spot in the yellow of the keels 
just above each repugnatorial pore. 

Type specimens. — Holotype, female allotype, and a male paratype 
in the U. S. National Miisemn, No. 1805; additional paratypes are 
retained in my personal collection, Nos. 6-3047-2a, T-147-lb, and 
7-14T-2a. Most of the above specimens were collected on June 30- 
July 1, 19-47, but one female was found in the saddle between Mount 
Rogers and White Top Mountain on eluly 15, 1947, by Dr. L. R. Cleve- 
land. 

Remarks. — This attractive species is fairly common on Mount Rog- 
ers below the evergreen forest line, and was frequently seen out during 
the day, crawling on logs and across the trails. One evening four 
specimens were taken as they wandered about atop an old sawdust 
pile. A pair was seen in copulation on the night of July 1. 

Deltotaria coronata is, apparently, the only xystodesmid milliped 
in eastern United States with the conspicuous and brilliant yellow 
band across the front of the collum. T]ie specific name is given in 
recognition of the marking. 

Genus NANNARIA Chamberlin 

Nannaria Chamberlin, Psyche, vol. 25, p. 124, 1918. (Geuotyye: Natinaria 
minor Chamberlin.) 

Small, narrow-bodied forms characterized in part by the repugna- 
torial pores being lateral in position and by the uniform dorsal pat- 
tern of olive to black with the keels pink. The gonopods consist of 
a nearly straight slender lateral process and a smaller mesial process. 

NANNARIA ERICACEA, new species 

Plate 27, Figures 9, 10 

Diagnosis. — A large member of the genus characterized by the male 
gonopods, in which the telopodite is deeply bifurcated with the larger 
lateral process bearing a mesially directed terminal branch, and the 
sm.aller mesial process a simple flattened blade which reaches distad 
to the level of the branch of the lateral process. 

Description. — ^Length of holotype, 30, width, 5 mm. Body width 
averages 16 percent of length. Segments between second and fifteenth 
of full width, body abruptly rounded in front, gently tapering behind. 

Collum large, rounded in front, sides straight and with small mar- 
ginal ridges; subtrapezoidal in dorsal aspect. Posterior margin in- 
dented across body, posterior corners angular. Collum not quite as 
long as two succeeding segments. 

Second segment with keels shorter than tergite at midline, posterior 
edges of keels tapering cephalad, marginal ridges well developed. 
Segments 3 through 12 subsimiliar, anterior corners of keels rounded, 
posterior corners directed slightly caudad; all keels with prominent

marginal ridges; keels extending caudad of median posterior portion 
of tergites. Segments 14 to 19 with posterior lobes equal in length 
to tergites at midline. All tergites comparatively flat and smooth. 
Repiignatorial pores lateral in position, in some cases directed slightly 
downward. 

Anal segment triangular in dorsal aspect, longer than broad, its 
basal width less than distance between keels of
