natalis form of this species. There is certainly nothing in the emargin- 
ation of the candal fin in which confinis and hoyt differ from the rest of 
the species with the caudal fin truncate, as has been supposed by Prof. 
Cope, on the strength of Girard’s description. 
The only good description of this species is that of Prof.’Gill, under 
the name of Amiurus obesus, in the report of Captain Simpson’s Explo- 
rations. I have no doubt of the identity of Rafinesque’s melas with 
the obesus. The obesus occurs in considerable abundance about the 
Falls of the Ohio, and Rafinesque’s description is reasonably accurate.
