312 MONOGRAPHS OF NORTH AMERICAN RODENTIA. 
labels the collector has written “Length 19 in.” The length of the ears and 
hind feet fully equal the dimensions of these parts im the largest specimens 
of var. virginianus, and indicate var. bairdi as perhaps the largest form of 
the group. The ears also appear relatively longer than in any other form. 
The skulls of which measurements are given are limited to two specimens, 
both immature, they still retaining the last temporary molar.* 
This variety appears to be strictly an alpine form, inhabiting the snowy 
summits of the higher portions of the Rocky Mountains. The specimens in 
summer pelage are, with one exception, all from the Wind River Mountains 
and other ranges near the head of the Yellowstone River, one being from the 
mountains of Colorado. Others, in winter pelage, are from the mountains 
west of Fort Benton, and from the Bitter Root Mountains near Fort Bridger, 
one also coming from as far south as Cantonment Burgwyn, New Mexico. 
I was informed by hunters and mountaineers, while west in 187], of the 
occurrence of a white hare with very large broad feet in the Snowy Range of 
Colorado, in the Medicine Bow Mountains of Wyoming Territory, and in the 
Wasatch Mountains of Utah, which I doubt not is referable to this variety. 
The hunters spoke of it as being peculiar to the snowy region, and as very 
different from the white Hare of the plains (Lepus campestris), or from any 
other species with which they were acquainted, in the great breadth of its 
heavily-furred feet.

* Several other skulls came to hand later, but I find that, through inadvertance, no measurements 
of them were taken before they again passed out of my hands.
