Fez., 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. (J. c., p. 140). Jackson records it from Dunn County, 
(I. ¢., 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 
(l.¢., 1910, p. 89). Thereisaspecimen 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., 1; (MI. P.M.) Prescott, 
Pierce Co., 1 = 2.
