BULLETIN OF THE UNITED STATES FISH COMMISSION. 
olive; broad metallic lateral band; iris red ; body in male flushed with brownish red; 
head and fins all bright yellow, without red; scales before dorsal smaller than in 
related species. 
12. Notropis niveus (Cope). J., C., P., T. 
(Including N. chloristius (Jordan & Brayton.) 
Abundant. This species is one of the most puzzling in its variations, and I am 
not yet sure whether it is really distinct from N. wMpplei, or whether, on the other 
hand, I have not confounded two species under the name niveus. 
All the specimens taken in the Catawba, and most of those from the Pacollet, are 
the typical chloristius. This form is very close to JSf. whipplei, the eye a little smaller, the 
head more slender, the blue stripe on side of tail more distinct. In these the eye is 4 
in head, and the body short and deep, the depth to 44- ; scales 36. Two of the 
specimens from the Pacollet, and most of those from the rivers farther eastward, cor- > 
respond best to the descriptions of N. niveus. In this form the body is elongate, com- 
pressed, with the back more elevated. Eye 3^ in head; depth of body 44 to 5 ; scales j 
39. The blue stripe on caudal peduncle is less distinct, and there is a trace of a cau- 
dal spot. Head subconic, the thickish snout projecting. The species from the Dis- 
mal Swamp region, identified by us as N. niveus, is not quite like either of these forms. 
It is certaiuly quite unlike chloristius. Our collection shows so many intermediate or 
indeterminable examples that I am compelled to record all under a single name, Notro- 
pis niveus. 
13. Notropis pyrrhomelas (Cope). B., C., J., P., T., F. 
The most abundant fish in the Santee basin, and one of the most showy of the 
Cyprinidce, the male retaining its bright colors through the summer. 
14. Notropis scepticus Jordau & Gilbert. J., C., T. 
Not rare. Close to N. anicenus, but with the snout shorter and blunter, the eye 
larger. Specimens show considerable variation in form, but all belong to one species. 
Scales before dorsal 14 to 16 (Catawba) to 18 (Pacollet). Green in life; sides silvery; 
no red. 
15. Squalius vandoisulus (Cuv. & Val.). B. 
Abundant in Buck’s Creek. Dark lateral stripe very obscure ; depth 4^ in length. 
16. Hybopsis hypsinotus (Cope). P. 
One specimen from Pacollet River. An ally of H. amblops. A dusky lateral band 
through eye and snout, ending in a faint caudal spot. Resembles N. procne, but with 
an evident barbel. 
17. Hybopsis labrosus (Cope). B., J., P. 
{CeraticMliys zanemus Jordau & Brayton.) 
Common in clear water. Male steel-blue ; a black spot on back at base of dorsal 
in front ; a dark shade under middle of dorsal ; a black blotch on membranes of dorsal, 
as in Notropis ivhipplei and niveus ; a dark caudal spot; a plumbeous shade on sides; 
caudal with a dusky shade on membranes; a dark shade on opercle; snout and all 
fins bright red ; female pale, with faint black blotch on dorsal, and with no red. 
This species is in form and coloration remarkably unlike all the others in the 
genus.
