Feb., 191 2. 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, 1908, p. 26); he also states there is a specimen in the University 

 of Wisconsin collection at Madison taken in Lema Township, Pepin 

 Co., in 1907 and scalps from Jackson, Dunn and Adams counties 

 (/. c, 1910, 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.
