Family Serranida^. 



Striped Bass, Yellow Bass {Morone interrupta, Gill). 



Young Avere fre(i[uent in certain of the sloughs and lakes, but 

 were not seen elsewhere. In the northern part of Broad Lake and in 

 small isolated pools above it, they were quite common. Examples 

 preserved vary from 1.75 inch to 4.50 inches in length. 



Localities: Ballard Slough, Harkness Slough, Goose Lake, Dead 

 Man's Slough, Glaus Lake, Willow Slough, Lily Lake, Broad 

 Lake. 



White Bass, Kock Bass {Eoccus 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 from 2 50 

 to 5 inches in length were found in the sloughs. It was nowhere 

 common except in the upper part of Broad Lake and in the pools 

 which had recently been in communication with it. 



Localities: Ballard Slough, Bear Creek, Goose Lake, Dead Man's 

 Slough, Moss Lake, Willow Slough, Long Lake, Broad Lake, Wood 

 Slough. 



Family Percid^. (Perch.) 



Sauger, Jack Salmon {StzosUedion canadense, Smith). 



Young frequent in lakes, varying from 3 to 5 inches in length. 

 No adults seen. 



Localities : Goose Lake, Glaus Lake, Lily Lake, Long Lake, Broad 

 Lake. 



Wall-eyed Pike {Siizosiedion vUreum, Mitch.). 



Young frequent in most of the sloughs and lakes; sometimes 

 abundant. Ranged from 2.50 inches to 6 inches in length. Fre- 

 quently with large, conspicuous, dusky blotches. 



Localities: Harkness Slough, Goose Lake, Willow Slough, Lily 

 Lake, Long Lake, Broad Lake, Wood Slough. 



Common Ringed Perch {Perca jlavescens, Mitch.). 



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 diflFered from the northern lake form in be- 

 ing rounder; and also especially in color. When taken from the water 

 they were almost uniformly olive green above, with white belly. 

 As they died, faint blackish bars gradually appeared. Mr. Bartlett 

 tells me that he has transplanted perch to this locality, — a fact 

 which probably accounts for the abundance of the fish in Libby 

 Lake.
