810 FISHES——-CATOSTOMID A. 
Carpiodes nummifer, COPE, Proc. Am. Philos. Soc. Phila., 1870, 484. 
Description.— Body fusiform, more elongate than in the other species, compressed, but 
not much arched; head quite short; muzzle short, but projecting much beyond the 
mouth ; eyes small, anterior 44 in head; first rays of dorsal short, extremely stout and 
osseous at base, the insertion of the first ray nearer the end of the muzzle than the base 
of the caudal fin ; color pale, as in all the other members of the genus; head 44 to 5; 
depth 24 to 3; D., 30; scales 7-36-5. Length, 1 to 14 feet; the largest species of the 
genus. 
Habitat, Ohio Valley, etc., abundant, often ascending smaller streams. 
Diagnosis.—This species may usually be readily distinguished by the 
small head and the thickened anterior rays of the dorsal. 
Habits.—This is the commonest species of its genus in the Ohio River, 
and it is often found in the streams of the interior of the State. It has 
not yet been recorded from Lake Erie. Like the others, it is used as food, 
but never highly valued.
