LAMPREYS AND FISHES OF INDIANA. 253 



of Brown County in Salt Creek (.?.i, '84, 204) ; Posey County (4., '88, 

 163) ; Evausville (4, '88, 166) ; Eel K. Basin {4, '94, 38) ; Cedar Lake 

 (Jo, 104). 



This fish probably has about the same habits and qualities as the pre- 

 ceding and closely related species. Professor Forbes {I4, No. 3, 57) tells 

 us that this species is commonest in the southern portion of Illinois. 

 When the size is below an inch, they seem to live entirely on entomostraca. 

 As the size increases, insect larvfe are added until the insect element be- 

 comes as much as thirty per cent, of the whole. The adults likewise eat 

 large quantities of entomostraca and the larvae of neuropterous insects. 

 The autumnal diet was found to include about one-third of .<mall fishes, 

 minnows, etc. 



This is one of the best of food fishes and it takes the hook readily.
