EUPOMOTIS — PUMPKINSEED SUNFISH 259 



and it is not excelled as a pan-fish by any of our species, unless 

 it be the yellow perch. The greater part of 4 the sunfish catch 

 of Illinois, amounting to 200,000 to 500,000^pounds a year, is 

 composed of this species. 



It spawns in May, according to our observations at Mere- 

 dosia, although Dr. Kofoid found a ripe male June 12.

This is a southern fish, and has occurred in our Illinois

 occurred in Indiana also, in the same stream and its tributaries, 

 and it has been lately taken in Little Eagle Lake in Kosciusko
