62 CONTRIBUTIONS TO NORTH AMERICAN ICHTHYOLOGY—II. 
Fin-rays:—D. I, 8; A. 1,8; V,8. Dorsal fin inserted slightly behind 
ventrals; pectorals scarcely reaching 3 to ventrals, the latter to vent. 
Seales moderately elevated, 6-44-3; lateral line strongly decurved, 
forming an abrupt flexure just before the ventrals,—a peculiarity usually 
well marked and characteristic. 
Teeth 1, 4-4, 1, strongly crenate. 
Color in spirits pale; sides silvery ; a pretty distinct black blotch on 
last rays of dorsal, as in C. analostana ; a large, distinct, black caudal 
spot, ovate in form, half larger than eye, and extending up on the mid- 
dle rays of caudal; the coloration therefore nearly that of Photogenis 
stigmaturus. 
Length 44 inches. 
Types, No. 6865, United States National Museum, from Black War- 
rior River, Alabama. Collector, Prof. Winchell. Many specimens. 
Other specimens from Tangipahoa River, Louisiana, are also in the col- 
lection. 
The species seems to resemble C. cercostigma Cope most, having a 
similar coloration ; but that species is said to possess the teeth 2, 4, and 
to have somewhat different proportions. Several other similarly col- 
ored species of Photogenis and Cyprinella inhabit our southwestern 
waters. 
44, PHOTOGENIS GRANDIPINNIS, sp. nov. 
Body short, much compressed; back elevated; the form generally 
that of a young Notemigonus. Depth 4 in length. Head short, 44 in 
length, pointed, flattened above; mouth large, very oblique, the jaws 
just equal; eye large, 3 in head, about equal to snout and to interorbital 
space. 
Tin-rays:—Dorsal I, 8; anal I, 10 or11. Dorsal fin entirely posterior 
to ventrals, midway between eye and base of caudal, the fin greatly 
elevated, the longest ray being a little longer than head; anal fin also 
greatly elevated, reaching to within one eye’s diameter of base of cau- 
dal; in smaller specimens less elevated, but in all very large, larger 
than in any other Cyprinoid known to me. 
Seales with the exposed edges very narrow, 6-35-3; 16 large scales 
before dorsal; lateral line much decurved. 
Color disappearing in alcohol; dorsal fin with the large black blotch, 
found in all the species of this group, unusually large and distinct, spread- 
ing forward on tbe anterior rays; a distinct black caudal spot, smaller 
than eye and deeper than long, running up on the middle rays; sides 
shining plumbeous; a very distinct bright silvery band from upper half
