The sexes of the above skulls are unfortunately unknown, although 
they are probably females. They are, however, decidedly smaller 
than two skulls from Minnesota supposed to belong to this species. 
The range of the Prairie Wolf or Coyote formerly included the greater 
portion of Illinois and Wisconsin and it is still to be found in more or 
less numbers in many sparsely settled localities in both states.t There 
is a specimen in the Northwestern University collection at Evanston, 
Illinois, taken near Geneva, Kane Co., Illinois. Mr. T. D. Shipton of 
Hanover informs me that they are of regular occurrence in parts of Jo 
Daviess Co., but not plentiful. Mr. W. L. Weaver of Morrison, White- 
side Co., reports them as being found to a limited extent in that locality. 
Mr. W. E. Nixon, county clerk, Toulon, Ill., informs me they are occa- 
sionally killed in Stark County. Mr. A. H. Howell states that several 
were killed two or three years ago near Kansas, Edgar Co. Kennicott, 
in his list published in 1854, states that it was abundant in Cook County 
within ten years (J. c., p. 578). 
In Wisconsin it is common in some localities. Hollister states that 
there are three skulls in the Biological Survey collection from Eagle 
River, Vilas Co., collected in 1907, and a skin and skull from Delavan 
taken in 1898. He is of the opinion that it is increasing in numbers in 
southern Wisconsin,- notably in Walworth County where several litters

+ It is probable that nearly all the so-called ‘‘ Gray Wolves” reported by various 
newspapers as having been killed, from time to time, in Illinois are this species.
