HABITAT. Great L?.ke Region to South Carolina and Texas. 



This fish, although a very abundant one in the Mississippi Basin, 

 see.ins to have been overlooked by most recent writers. Rafiuesque 

 described it rather poorly. Dr. Kirtland was able to recognize the fish 

 from Rah'uesque's account, and has given a very good description and 

 an indifferent figure. Valenciennes described it fairly, and Agassiz 

 seems to have been acquainted with it, although, deceived by its exter- 

 nal appearance, he took it for a Myxostoma (Ptychostomus}. Girard next 

 described and figured it as two species, belonging to two different genera. 

 Professor Cope, for some reason, did not obtain it in any of his collec- 

 tions, and seems to have had much difficulty in identifying Kirtlaud's 

 account. In 1875, the writer, noticing certain resemblances to Erimyzon 

 ollongus, was led to dissect a number of individuals, and found that the
