9. Notropis procne (Cope). S., B. 
Common, especially in the creeks, in water not very cold. Specimens from Swift 
Creek have the back rather broader and less elevated than in those from Luray. 
Scales 35; scales of back dark-edged ; a lateral streak made of dark points; two faint 
dark spots, one behind the other, at base of caudal. This is a very characteristic color- 
mark, at least traces of it being found in all specimens. 
10. Notropis saludanus (Jordan & Brayton). S., E. 
Common in Swift Creek only. Color pale; a dark caudal spot in young only. 
Interorbital width, 3 in head ; head, 4| in length. 
11. Notropis rubrifrons Cope (var.?). B., E. 
Common in the creeks, especially in Buffalo Creek. Color silvery ; snout, chin, 
and bases of all the fins rosy in the males only; twenty scales before dorsal. Usually 
no black at base of anal. This species shows much variatiou in form. Some are very 
slender, the depth 6 in length, but most have the depth 5J. These all have the dorsal 
about two scales nearer in its insertion to snout than to fork of caudal. 
Two specimens from Buffalo Creek agree in most respects, but are decidedly deeper 
and more compressed, the depth 4| iu length ; the lateral line i)roportionately more 
curved and the dorsal further forward, only a scale nearer base of caudal than to tip 
of snout. Iu these the pectoral is also longer, almost reaching base of veutrals. The 
eye iu all is 3 to 3J in head. Probably all belong to one species, but, if so, the varia- 
tions in form are unusual. Compared with Indiana specimens of W. rubrifrons these 
have the eye a little larger and the head a little shorter (eye 3|^ to 3J in head, not 3§ 
to 4). Notropis dilectus (Girard), Arkansas to Texas, is very close to N. rubrifrons. 
Specimens from Bed Eiver, Arkansas, are more compressed, with shorter snout, 
bluntish and not as long as the small eye, which is 3 in head. Head 4J in length, 
twenty scales before dorsal. 
12. Notropis amoenus (Abbott). L., S., N. 
Common in the channels of the larger streams. This species is quite variable, and 
some examples are scarcely distinguishable from N. rubrifrons. It reaches, however, 
a larger size. It is usually deeper iu body, with smaller scales before dorsal and no 
red even in the males. A. 11. In Swift Creek specimens are usually but nineteen 
scales before dorsal. One of these specimens has a much deeper body, nine anal 
rays, and twenty-four scales before dorsal. Its appearance suggests a possible hybrid 
of amoenus and megalops., though it may prove to be the young of the variety of N. 
megalops, which is common in the Roanoke. 
13. Notropis analostanus (Girard). L., S., B., N., E. 
Common ; specimens vary a good deal in form, but most are deeper in body than 
western specimens (depth 3f to 4J), and the scales iu the lateral line are usually but 
thirty-five. 
14. Notropis macdonaldi Jordan & Jenkins. B., N. 
One specimen from Buffalo Creek ; another from Loch Laird. 
15. Notropis megalops (Eafinesque). L., S., B., N., E. 
Common ; similar to northern and western examples. 
16. Hybopsis kentuckiensis (Rafinesque). L., S., B., N., E. 
Common.
