5. Catostomus nigricans (Le Siieur). S.,H,W. 
Equally common, but in swift waters. 
6. Hybognathus nuchalis Agassiz. W. 
Three rather small specimens. Compared with examples from Parke County, 
Indiana, these are a little less elongate and darker in color, with a plumbeous lateral 
band, and back and sides thickly punctate. 
7. Notropis megalops (Rafinesque). H., W. 
Common only at Waynesborough. 
8. Notropis macdonaldi, Jordan & Jenkins. W. (Jordan & Jenkins, Proc. U. S. Nat. Mus,, 1888, 
p. 354). 
Five specimens. The types of this interesting new species were obtained in the 
cold waters at Waynesborough. 
9. Notropis aualostauus (Girard). S., H., W. 
Common. Compared with specimens of the western species or variety, W. whipplei 
from White River, Indiana, the Virginia examples are less elongate (depth of adult 
male in length instead of 4) and the scales are larger (lat. 1. 34 or 35 instead of 38 
to 40). These characters, already noticed by Professor Cope, seem to be reasonably 
constant. For the present, therefore, I retain N. analostanus as a species distinct from 
N. whipplei. 
10. Notropis amoenus (Abbott). S., W. 
Common, especially at Luray. This species is closely related to N. ruhrifrons, but 
deeper in body, more compressed, and with notably smaller scales before the dorsal. 
These specimens vary a good deal among themselves, those from the river at Luray 
being larger, much paler iu color, and with decidedly larger eye as compared with 
those from Waynesborough. The latter resemble W. ruhrifrons more closely than the 
former, but all probably belong to the same species. 
The largest specimens approach in form the rather poor figure given by Abbott of 
his Alhurnellm amcenus,^ and they are probably specifically identical with the latter, 
as Abbott’s description agrees in all essential respects. Head, 4; depth, 5J^ (4| to 
5^). D. 8, A. 10. Scales, 6-39-3. Length (Luray), 3|-inches. Body elongate, com- 
pressed, the form varying somewhat. Head sub-conic, more or less compressed; eye 
large, rather longer than snout, about 3J iu head, its size largest iu Luray specimens. 
Mouth large, oblique, the maxillary reaching to just past front of eye, the jaws about 
equal when the mouth is closed. Scales of back smaller than in related species, there 
being 22 to 25 (rarely 18 to 20) rows between the occiput and the dorsal fin. Lateral 
line much decurved. Dorsal fin inserted behind veutrals, rather high, and rather 
large, its free edge concave ; pectorals moderate, scarcely reaching ventrals, which 
extend to vent. Color translucent green ; sides silvery, iu some specimens a faint 
plumbeous band ending in an obscure plumbeous spot. Some specimens with dark 
points along lateral line. Fins plain. 
This species is abundant in the river channels, both at Luray and at Waynes- 
borough. Numerous specimens were taken. Specimens from the Potomac similar to 
these have been formerly identified by me as Notropis photogenis (Cope). It may be
