CARPIODES BISON. 197 



18i6—Sclcrognat7ius cuprinus Kiiitland, Bost.. Journ. Nat. Hist. vol. v, 275. (In part ; 

 not of C. & V.) 



Habitat.— Western streams and lakes (Cayuga Lake, New York, to Mississipri 

 Iliver). 



This species is quite abundant in the Ohio River, and I have seen 

 specimens not evidently.distinguisbable, from Lake Erie and from other 

 waters tributary to the Great Lakes. Indiscriminately with C. cutis- 

 anscrimis, it is known to the fishermen as Quillback, ISkimback, etc., 

 tbe lower-finned species being called ratber "Carp". Most of the 

 synonymy above quoted includes several species, the true vclijer being 

 first distinguished by Professor Cope. Rafiuesque's anisopteriis I bring 

 into the synonymy of tbis species, simply to refer to it somewhere. It 

 is really unidentifiable. Kirtland's Sclerognathus cyprinus refers most to 

 tbis species, but his figure represents no known fish. The head is too 

 small, and the form, etc., incorrect.

What the fish is to which Professor Agassiz gave the name '•'- bison'''' 

 cannot be ascertained from the published descriptions. Professor Cope 

 has described the present species under that name, and we accept the
