NOTES ON TEXAN FISHES, WITH DESCRIPTIONS OF NEW SPECIES. 
The brief time allowed for the preparation of the first part of this report was not 
sufficient for a critical study of all the material collected. Only the species of Cyprin- 
oids and Cyprinodonts have been thus far carefully studied, and it has seemed best to 
publish in this connection the results of the study of only those two families, reserving 
for another paper the report upon the other fishes collected. In that paper will also 
be given illustrations of the other new species here described. 
1. Campostoma anomalum (Raf.). 
One specimen, 4 inches long, from the San Marcos River near San Marcos. Head, 
4g; depth, 5£; eye, 4; D. 9; A. 7; scales, 8-54-7. Compared with specimens from the 
Yellow River, at Plymouth, Indiana, the Texas specimen has the scales smaller (7-46-5 
in the Yellow River specimens), the lateral line less decurved, interrupted on about 10 
scales of the caudal peduncle, reappearing upon the last 4 or 5 scales. 
The types of C. formosulum Girard came from San Antonio, and have the scales 
about the same as the Indiana specimens. 
2. Dionda episcopa Girard. 
One specimen 2f inches, and one 1A inches long, from the Comal Spring, New 
Braunfels. Head, 44; depth, 4J; eye, 3; H. I, 8 ; A. I, 8; scales, 7-40-4 ; teeth, 4-4; 
grinding surface well developed; intestine long; peritoneum black. 
Body rather slender, head moderate ; origin of dorsal over ventrals, a little nearer 
tip of snout than base of caudal, its base two-thirds its height or one-half length of head. 
Color in alcohol, dark olive above, covered with numerous fine, dark specks; side, 
with a broad plumbeous band, running from tip of snout through middle of eye to 
base of caudal, where it ends in a black blotch, this band for the most part lying just 
above the lateral line; lower jaw, suborbital, lower opercular region, and body below 
lateral line, pale but with a few scattered dark pun delations. 
In his “Researches upon the Cyprinoid Fishes Inhabiting the Fresh Waters of the 
United States West of the Mississippi Valley,”* Girard establishes the genus Dionda 
and described as new ten species belonging in it (Dionda episcopa , serena , texensis , 
papalis, argentosa, chrysitis, plumbed , melanops , con chi , and spadicea). The first seven 
of these species were described from Texas waters, the next two from Mexico, while 
the last one named was from Fort Smith, Arkansas. In 1885 all the types of these 
species that could be found either in the U. S. National Museum or in the Philadelphia 
Academy were studied by Dr. Jordan, who gavet the following identifications: 
Girard’s species.
