24 CONTEIBUTIONS TO NORTH AMEEICAN ICHTHYOLOGY 1, 



beautiful and singular coloration of that species — a chain of rounded, 

 confluent, black blotches on a yellowish ground — would surely have been 

 noticed. Moreover, the pattern of color of Eafinesque's fish is exactly 

 that of a young '■^Hyostoma cymatogrammum'K Furthermore, the charac- 

 ters "head small", "snout rounded", "mouth small, beneath", "cheeks 

 swelled", "dorsal 13 and 13", "a brown stripe upon it", etc, apply per- 

 fectly to the '^Eyostoma^^ and not to the '■^Mheostoma^\ In the streams 

 where Eafinesque collected, I find the former species much the more 

 abundant.
