GENus 44. PHOXINUS. Agassiz. 
Phoxinus, AGAssiz, Mem. Soc. Sc. Neufchatel, 1, 37. 
Type, Cyprinus phoxinus L. = Phoxinus levis Ag. 
Etymology, phoxinos, a minnow, from phoxes, tapering. 
Body stout ; mouth normal, without barbels; teeth 2, 5-5, 2, or 2, 5-1, 2, hooked, with- 
out grinding surface ; scales small, but little insbricated ; Jateral line incomplete or want- 
ing; dorsal fin behind ventrals, anal basis short; species of small size and brilliant col- 
eration; found both in Europe and America. The resemblance to Chrosomus in form, 
gequamation, and coloration is considerable, but the teeth and alimentary canal are quite 
different. Three species are known in America, and two or three in Kurope.

Mus., vii, 247.— JORDAN, Man. Vert., 2d Ed., 1578, 302. 
Descriplion.—A stout little fish, with the head large, short, and blunt anteriorly ; mouth 
rather small, chique, terminal, reaching about to the frent of the eye; eye mederate, 
rather longer than muzz!e; color blackish, a black lateral band, above which is a pale 
streak; a dark spot at baee of caudal; belly pale, crimson in the males in spring; 
head 3 4-5; depth 41-5; D, 8; A. 8; scales 18-77-12; lateral line developed on about 24 
scales; teeth 2, 5-4, 2. Length 24 inches. 
Habitat, Southern Michigan to Minnesota. 
Diagnosis.—This species may be known by its very small scales and in- 
complete lateral line. From Chrosomus eryihrogaster it may be best known 
by the presence of two rows of teeth. 
Habits. —This little fish has bee. thus far noticed only in Southern 
Michigan, Southern Wisconsin, and Northern Illinois. It doubtless oc- 
curs in North-western Ohio. Its habits are probably very similar to 
those of Telestes elongatus.
