86 CONTRIBUTIONS TO NORTH AMERICAN ICHTHYOLOGY—II. 
Color very dark. The type-specimen is quite black, both body and 
fins; the belly is pale, but the lower barbels as well as the upper ones 
are black. 
The type was collected in the St. John’s River, Florida, by Mr. G. 
Brown Goode. It is a little more than a foot long. 
This species is intermediate between A. lupus and A. lividus, having 
the narrowed head, high dorsal, and small mouth of the first, with 
the short, truncate candal fin of the second.
