 (14, No. 3, 49) varies with the locality inhabited. In the ease of the 

 fishes taken from clear inland lakes, about two-thirds of the food consisted 

 of the larvae of neuropterous insects, the remaining third of the crustacean 

 'Allorchestes dentata. Specimens taken from Calumet River and Lake 

 George were peculiar in the large numbers of Allorchestes and Asellus 

 eaten. Sj)ecimens taken from the Illinois River had eaten considerable 

 quantities of mollusks and land insects, as well as vegetable matter to the 

 amount of one-third the whole.
