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



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

 Wabash River, in which stream Professor Cope's original types were 

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

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

 BuCfalo-fish.
