This species resembles A. catus, but is distinguishable by the short 

 anal tin. From A. melas the broader head and some other peculiarities 

 separate it. It is possible, however, that it is a variety of the latter 

 species.

Habitat — North Carolina to Georgia. 



This species has the form of Pelodichthjs, as well as the increased 

 number of branch iostegals. The dorsal spine is, however, well devel- 

 oped, and the anal fin has the usual number of rays, although only 17 

 were counted by Prof. Cope. The lower jaw does not project, and the 

 dentition is of the pattern usual in Amiurus.
