Habitat. — Western New York to Northern New England. 



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. 



20. AMIUEUS BRUNNEUS, Jordan.

Habitat. — Ocmulgee Eiver, 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 PelodichtJiys, 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.
