The range of the Wisconsin Gray Fox is not definitely known, but 

 it probably occurs throughout the greater portion of Wisconsin and 

 also in northern Illinois. Kennicott states that Gray Foxes were 

 formerly not uncommon in Cook Co., Illinois (/. c, p. 578), which may 

 or may not have been this form. I have seen no specimens from this 



Map showing the type localities of races of Gray Foxes in eastern United States. The range 

 limits of the various forms have not been satisfactorily determined. 



Urocyon cinereoargenleus (Schreber). Type locality — Eastern North America, 

 probably Carolina or Virginia. Description as previously given. 



Urocyon c. ocythous Bangs. Type locality — Platteville, Grant County, Wiscon- 

 sin. Description as previously given. 



Urocyon c. floridanus Rhoads. (Proc. Acad. Nat. Sci. Phila., 1895, p. 42.) Type 

 locality — Tarpon Springs, Hillsboro County, Florida. Smaller than cinereo- 

 argenleus; breast paler, but without white under parts. 



Urocyon c. borealis Merriam. (Proc. Biol. Soc. Wash., XVI, 1903, p. 74.) Type 

 locality — Marlboro, near Monadnock, New Hampshire. "Similar to cine- 

 reoargenteus, but decidedly larger, with marked skull and tooth differences." 

 (Merriam).
