FEB., 1912. MAMMALS OF ILLINOIS AND WISCONSIN CORY. 149 



Illinois, informs me that he found one in a burrow under a corn-shock, 

 active in mild weather, late in November. 



"This species is carnivorous, though apparently less so than the 

 striped spermophile. The specimen kept by Professor Baird was 

 decidedly carnivorous, but one observed by Dr. Hoy did not eat mice, 

 though it killed them when placed in its cage. Its food is generally 

 similar to that of the striped spermophile, stores being also found in its 

 burrow" (/. c., pp. 79-81). 



Mr. Vernon Bailey gives the following list of the various kinds of 

 food found in the stomachs of 29 animals of this species: "Beetles, 

 large and small species (Coleoptera) , Larvae of beetles (Coleoptera), 

 Caterpillars (larvae of Lepidoptera) , Grasshoppers and Crickets (Orthop- 

 tera), Ants, Eggs of insects, Chrysalis, Feathers of small bird, Sper- 

 mophile hair (probably their own), Grain (wheat and oats), Seeds of 

 basswood (Tilid), Strawberries, Solanum berries, Herbage (stems and 

 leaves of plants, among which only an Equisetum could be recognized) , 

 Roots" (/. c., p. 55).
