Sand Darter {Etheostoma jessicB, Jor. & Brayt., var. asprigene, 



Forbes). 



Judging by the number of specimens of this little fish taken, it ' 

 is not common here, although parts of Willow Slough are well 

 suited to it. '' 



Four examples, Willow Slough; one large brightly colored ex- 

 ample, Broad Lake; one example, Lily Lake. 



Sand Darter (Eiheosioma plioxocephalum, Nelson). 



Occasional in Wood Slough. Excepting a single example from * 

 Willow Slough, it was not seen elsewhere. 



Black-sided Darter ' {Etheostoma aspro, Cope & Jor.). 



One small example approaching E. jjtioxoceplialum in colors, was 

 taken in AVood Slough, July 30. 



Log Perch (Etheostoma caprodes, Raf. ). 



This was the most abundant darter collected. It was quite 

 common in Willow Slough, Long Lake, Broad Lakfe, and Wood 

 Slough. 



Johnny Darter (Etheostoma nigrum, Raf. ). 



An immature example from Willow Slough was the only one 

 seen. 



Family Centrarchid.e. (Sunfishes.) 



Large-mouthed Black Bass (Microptcrus satmoides, Lac). 



The young of this bass were moderately common in all the 

 sloughs and creeks. Examples of considerable size were occa- 

 sionally taken, showing that this species does not necessarily 

 leave the sloughs after spawning. One example brought in by the 

 net must have weighed seven pounds or more. The smaller ex- 

 amples, which are of interest as in all probability tlie young of 

 the season, ranged from 2 to 3 inches in length. Between these 

 and the larger ones were various intermediate sizes representing 

 probably three or four generations.

 Cedar Creek, Lily Lake, Long Lake, Broad Lake. 



Small-mouthed Black Bass (Micropferus dotomieu, Lac). 



A single young specimen, 2.12 inches long, was taken in Willow 

 Slough August 7 The locality is somewhat unusual for this species. 

 It is certainly not common in the water collected from. Mr. Bartlett 

 informs me that it was brought here some time ago by the State 

 Fish Commission.
