EXPLORATIONS OF THE ALLEGHAisY REGION AND WESTERN INDIANA. 141 
9. Notropis pliotogeiiis (Cope). R. 
A species which 1 identify with Cope’s description is not rare in Eeed Creek. It 
closely resembles A. rubrifrons (specimens from White Eiver, at Indianapolis); size, 
form, and color similar. The eye, however, is larger (3 in head), and there are 25 
scales before the dorsal instead of 16. Compared with A. amoenus, from Luray, the 
eye is smaller, the body is more slender, and there are no black specks along the base 
of the anal fin. Color pale, a bluisb streak along side of caudal peduncle ; some dark 
points along lateral lines. Scales 40. 
10. Notropis atherinoides (Rafiuesque). P., R. 
Common in quiet j)laces ; reachiug a length of 4 to 6 inches. Color translucent 
green; sides bright silvery. Head 4|^ in length; depth 54; maxillary 2|- in head; 
eye 34 to 3. I refer these specimens to N. atherinoides {=rubellus Agassiz), without 
being quite certain whether the latter name includes more than one species. This is 
evidently the species called by Cope Alburnellus jacnlus. 
Specimens from the Holston Eiver agree fully, except that they are a little more 
slender in body ; depth 6. 
Specimens from Deer Creek, Indiana, called by Evermann and Jenkins Notropis 
arge^ and evidently Alburnellus urge Cope, are a very little more robust, but have i)re- 
cisely the same eye, snout, and mouth. 
Specimens from the falls of the Ohio {N. dinemus Eafinesque) are a little stouter, 
the eye a shade smaller; the eye, mouth, and head notably shorter; head 4f in length ; 
eye equal to snout ; 3J in head; maxillary 3^ in head. 
Other specimens [dinemus) from Pipe Creek (White Eiver), near Anderson, Ind., 
are similar, but with the snout and mouth longer, thus approaching urge. 
Still other specimens from Deer Creek, called atherinoides by Evermann and 
Jenliins, have the eye notably smaller and the snout sharper. 
N. amoenus, from Luray, is stouter and more compressed, with stouter head and 
smaller scales before dorsal. It is also less silvery in color. In form of eye and mouth 
this species scarcely differs from N. atherinoides [arge). 
11 . Hybopsis kentuckiensis (Rafiuesque). P., R. 
Common. 
12 . Semotilus atromaculatus (Mitchill). P., R. 
Common ; scales 55. 
13. Rhiniclithys cataractae (Cuv. & Val.). R. 
Not common; scales about 70. 
14. PHoxinus margaritus (Cope). R. 
Eather scarce. Scales smaller than in eastern examples. Perhaps this may 
prove to be a different species. Head 4^ in length ; dei>th nearly the same ; mouth 
very small, anterior ; scales52 to 54 (58in wurpcriD/s); 28 scales before dorsal ; dorsal 
quite low, inserted behind ventrals. Color dark, a very distinct caudal spot, and a 
well-defined black lateral band. The specimens are all small, the largest 2 inches 
long. 
15. Micropterus dolomieu (Lac6pede). P., R. 
Extremely common. As already stated, the Big Peak Creek is stocked with black 
bass, to the exclusion of everything else.
