I have not seen this fish. Mr. Audubon describes 

 it as a peculiar species, found in the Mississippi and 

 the lower part of the Ohio, being entirely similar to 

 the common Buffalo-fish, but larger, weighing some- 

 times upwards of fifty pounds, and living in separate 

 shoals. 



3d Subgenus. Carpiodes. 



Body oblong, somewhat compressed; head com- 

 pressed, nine abdominal rays, dorsal fin commonly 

 elongate, tail equally forked. 



The C. cyprinus and C. setostis, of Lesueur, belong 

 to this Subgenus. 



57th Species. Olive Carp Sucker. Catostomus 

 carpio. Catostome carpe. 



Diameter one fourth of the length: olivaceous 

 above, pale beneath, chin white, abdomen bluish: 

 lateral line straight, dorsal fin somewhat falcated 

 with 36 rays, anal trapezoidal with 10 rays; head 

 sloping, snout rounded. 



Seen at the falls of the Ohio, commonly called 

 Carp. Length from one to two feet. Eyes very 

 small and black, fins olivaceous brown, the pectorals 

 olivaceous, trapezoidal short and with 16 rays. Tail 

 with 24. Dorsal fin beginning before the abdominal 

 and reaching the end of the anal fin. Not so good 

 to eat as the Buffalo-fish. 



[II. 301 i.e., 303] 58th Species. Sailing Sucker. 

 Catostomus velifer. Catostome volant. 



Diameter less than one fourth of the length : body 

 elliptical, silvery with golden shades, lateral line 

 flexuose, dorsal fin very broad falcated with 25 rays, 

 the first ones very long, anal fin trapezoidal lunulate 

 with 10 rays: head sloping, snout rounded.
