24 CONTRIBUTIONS TO NORTH AMERICAN ICHTHYOLOGY 1. 



beautiful aud singular coloration of that species — a chaiu of rounded, 

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

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

 that of a young '•^Hyostoma cymatogrammum'\ 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 ^'■Utheostoma^\ In the streams 

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

 abundant.
