140 Illinois State Laboniforij of Nafural History. 



Redeye, Blue Spotted Sunfisu {Lepomis cijanellus^ Raf. ). 

 Two examples about 3.50 long, taken in Goose Lake, A.ug. 

 13, were the only ones seen. 



Waemouth, Red-eyed Bream {Chamobryttiis gulosirs^ C. & V.).

 the pools. Frequent in Libby Lake and Harkness Slougli. 



Localities : Ballard Slough, Harkness Slough, Libby Lake, 

 Dead Man's Slough, Claus Lake, Lily Lake, Long Lake, Wood 

 Slough. 



Pale Croppie {Pomoxys annularis^ Raf.). 



The pale croppie was more abundant than we have found 

 it elsewhere in the State away from Southern Illinois. This 

 fact is one of a number which our fish fauna yields, illustrating 

 the influence of the Mississippi River in extending the range 

 of southern species northward immediately along its course. 

 Young, from 2.25 to 2.75 inches long, were common ; and be- 

 tween these and the largest taken (8 inches long) were a 

 number of intermediate sizes. The species became a little more 

 abundant in the more northern pools. 



Localities : Ballard Slough, Harkness Slough, Goose Lake» 

 Libby Lake, Moss Lake, Dead Man's Slough, Claus Lake, Wil- 

 low Slough, Lily Lake, Long Lake, Broad Lake, i)ool at southern 

 limit of Quincy. 



Dark Croppie, Calico Bass {Pomoxys sjxiroides., Lac). 



A little more abundant than the preceding species in the 

 sloughs and lakes. Especially common in the more northern 

 pools, but very generally distributed. Most of those seen were 

 young, from 1.50 inch to 2 inches long. No adults were seen 

 from pools outside the levee. 



Localities : Ballard Slough, Harkness Slough, Goose Lake,
