Fes., 1912. MamMats oF ILLINOIS AND WISCONSIN—CoRY. 375 
Measurements — Total length (male), about 18 in. (455 mm.); tail 
vertebra, about 6.50 in. (164 mm.); hind foot, 2.15 in. (55 mm.). 
Female smaller; average length about 15 in. (380 mm.); tail, about 
5 in. (125 mm.). 
There are two specimens in the collection of the Milwaukee Public 
Museum (one in winter and the other in summer pelage) from Prescott, 
Pierce County, Wisconsin, which I have provisionally referred to this 
subspecies. In the coloration of the under parts in summer pelage they 
resemble spadix, but they are by no means typical and the cranial 
characters and comparative length of the tail strongly suggest inter- 
gradation. Unfortunately very few Wisconsin specimens are available 
for examination and I have seen but two examples in summer pelage. 
When a good series of Weasels can be secured from northern Wisconsin 
it is not unlikely that the range of P. n. occisor may be found to extend 
into that region.

Type locality — Northeastern North America; exact locality unknown. 
Distribution — Northern United States and southern Canada, in the 
East south to Wisconsin and Michigan and in the mountains of 
Pennsylvania; in the West its range extends in Canada to the 
Pacific Coast and in the United States in the Rocky Mountains at 
least to Colorado. 
Special characters — Smaller than noveboracensis and tail shorter. In 
summer the whitish portion of inner sides of hind feet usually more or 
less tinged with yellow. 
Description — In summer: Upper parts and legs dark brown; under 
parts generally including the upper lip, white, more or less washed 
with yellowish; toes whitish; inner sides of hind feet whitish, more or 
less tinged with yellow; end of tail black; no brown spot back of 
angle of mouth. 
In winter: Entire pelage, except end of tail, white, washed with 
yellowish on rump and under parts; end of tail black. The size is 
variable and the female is much smaller than the male.
