cc. Body elongate, not much elevated, the depth 2f in length: head 3f to 4, 

 the muzzle prominent but rather blnntish : front scarcely concave above 

 eyes, the profile forming a somewhat uniform curve: eye small, nearly 6 iu

caudal : scales 6-37-5: D. 24 to 27, A. 8, V. 10 cyprixus, 48. 



hhh. Head comparatively short, its length contained 4^ to 5 times in the length 

 of the body: body more fusiform than ip the others, compressed, but not 

 much arched, the depth 2f to 3 times iu the length: anterior rays of dorsal

Habitat. — Ohio Valley ; less common than the other species. 



The only specimen which I have seen of this species was from the 

 Wabash Elver, iu which stream Professor Cope's original types were 

 collected. No specimens are in the United States National Museum, 

 which, indeed, at present contains very few of the Carp Suckers or 

 Buffalo- fish.
