Feb., 1912. Mammals of Illinois and Wisconsin — Cory. 305 



locality, but it would be expected to intergrade with U . cinereoargenteus 

 in northern Illinois. The type was taken in Grant County, Wisconsin, 

 and Hollister records two specimens which he collected at Delavan, 

 Walworth Co. (/. c, p. 140). Jackson records it from Dunn County, 

 (/. c, 190S, p. 26); he also states there is a specimen in the University 

 of Wisconsin collection at Madison taken in Lema Township, Pepin 

 Co., in 1Q07 and scalps from Jackson, Dunn and Adams counties 

 (/. ("., i9io,p. 89). There is a specimen in the Milwaukee Public Museum 

 from Prescott, Pierce Co., and hunters have reported Gray Foxes from 

 Jefferson County. Gray Foxes are reported from Jo Daviess Co., 

 Illinois, but I have seen no specimens from that locality. The habits 

 of this northern race probably do not differ from those of the Gray 

 Fox. 



Specimens examined from Wisconsin: 

 Wisconsin— (B. S.) Delavan, Walworth Co., i; (M. P.M.) Prescott, 



Pierce Co., 1 = 2.
