White Bass, Rock Bass {Roccus chrysops, Raf.). 



This fine species was more abundant than the striped bass, 

 and ranged in a greater variety of situations. I saw it caught 

 from the swiftest current of the river. Only young ranging

 was nowhere common except in the upper part of Broad Lake 

 and in the pools which had recently been in communication 

 with it.

Young ringed perch were occasionally seen in the bottom- 

 land lakes. Those captured ranged from 2.75 to 3 inches in 

 length. In Libby Lake, within the levee, these fishes were 

 abundant, — a fact which was noted with surprise, as they had 

 not hitherto been found common in the State away from the 

 northern part. Those taken from this lake differed from 

 the northern lake form in being rounder; and also especially in 

 color. When taken from the water they were almost uniform- 

 ly olive green above, with white belly. As they died, faint
