Common Sunfish {Lepomis pallidiis, Mitch.). 



Rare in the temporaiy pools, becoming common in the deeper 

 water of Long and Broad Lakes; also quite common within the levee. 

 The youngest examples taken ranged from 1 inch to 1.7 i inches 

 in length. Adults in breeding colors were caught in Long and 

 Libby Lakes. Females contained ova as large as No. 12 shot. 

 An old gentleman who has fished here for years tells me that in 

 the days of the early .settlers sunfishes, presumably of this species, 

 were sometimes taken that weighed as' much as four pounds.

 Man's Slough, Moss Lake, Willow Slough, Lily Lake, Long Lake, 

 Broad Lake, Mississippi River. 



Red-spotted Sunfish (Lepomis humilis, Gir.). 



This handsome little fish was quite common in sloughs and 

 lakes, — more abundant than we have found it elsewhere in the 

 State. Very few young were seen, and these were nearly mature. 

 It is quite hardy, as is shown by the water it frequents, and may 

 prove a desirable aquarium fish. All the adults taken differed 

 fi'om the descriptions of Drs. Jordan and Gilbert in having the 

 opercular flap with a wide ichite margin instead of a red one. 

 Immature examples have the opercular flap poorly developed and 

 are marked in the sides with numerous small black dots, while 

 the red of the adult is largely wanting.

Red-eye, Blue Spotted Sunfish {Lepomis cjjaneUus, Raf. ). 



Two examples about 3,50 long, taken in Goose Lake, Aug. 13, 

 were the only ones seen. 



Warmouth, Red-eyed Bream {Chamobryttus gulosus, C. & Y.). 



A few young, about 1.50 inch long, were taken in most of the 

 pools. Frequent in Libby Lake and Harkness Slough.

 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 in- 

 fluence of the Mississii3pi River in extending the range of south- 

 ern species northward immediately along its course. Young, from 

 2.25 to 2.75 inches long, were common; and between 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.
