This species resembles A. catus, but is distinguishable by the short 
anal fin. 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. 
20. AMIURUS BRUNNEUS, Jordan. 
Small Brown Cat.

Habitat.—Ocmulgee River, Georgia. 
This species is one of the most strongly marked of the genus. It 
bears some resemblance to the species of Noturus.

Habitat.—North Carolina to Georgia. 
This species has the form of Pelodichthys, as well as the increased 
number of branchiostegals. 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.
