812 FISHES — CATOSTOMIDJE. 



Diagnosis. — This species may usually be known by the large head. 

 Habits. — I have seen but very few specimens of this species, all from 

 the lower Ohio. It is probably rare in this State.

Sclerognathus cyprinus, Kirtland, Bost. Joarn Nat. Hist., v, 1846, 275. (In part ; not of 

 Cuv. and Val.) 



Description. — Body rather deep, the back arched ; head moderate, the muzzle conic, 

 projecting, obtusely pointed; end of the mandible reaching to opposite the nostrils; 

 anterior suborbital as deep as long ; eye moderate, 4 to 4i in head ; first rays of dorsal 

 very high, inserted nearer muzzle than base of caudal ; color pale ; head 3f ; depth 2i 

 to 2i ; D., 26 ; soalos 7-37-5. Length, one foot. 



Habitat, Great Lakes and Mississippi Valley. 



Diagnosis. — This is the only species with the snout conical and the 

 long rays of the dorsal longer than the base of the fin. 



Habits. — This species is abundant in the Ohio River, where it is usually 

 known as Quillback, Spear-fish, and Sailor, its lower finned relative, C. 

 carpio, being usually known as Carp. I have seen none from Lake Erie, 

 but as it occurs in the lakes of Western New York, it will doubtless be 

 found there.
