Fremont's Squirrel 
i8s 
fined quite closely to the yellow pine timber, and are of 
similar habits. They build nests of pine boughs and twigs 
in the branches of the trees, lined with grass. According 
to examinations made by Dr. Mearns of piegnant females, 
the number of young at a birth is from 3 to 4; they breed 
in spring or early summer. The food consists largely of the 
seeds of the pines, which they extract from the cones, and 
the spots where a squirrel has been feeding are easily located 
by the chips and cores of the cones. 
The ear tufts are shed in the spring, and the new ones do 
not attain their full growth until early winter, hence summer- 
caught specimens have the ears nearly or quite tuftless. A 
specimen taken by me near Colorado Springs, May 14th, has 
nearly full ear tufts, but the body pelage has nearly all been 
shed, except on the rump, and the new hair is just beginning 
to grow. This was a gray specimen.

(1853). 
Type locality. — "Rocky Mountains," probably in the South 
Park, in Colorado. 
Measurements. — Total length, 13; tail vert., 5; hind foot, 2. 
Description. — Color of back mixed gray and rusty, these colors 
being on the tips of the hairs, which are blackish at the base; 
beneath lighter, almost white in summer, grayer in winter. In 
summer pelage there is a distinct black lateral hne, bordered above 
by rufous, and this latter is the color of the upper surfaces of the 
feet; top of head quite dark in summer. In winter pelage the 
lateral line is entirely or practically absent, as also the rufous of the 
sides and feet. Tail dark above and below, with fringe of white- 
tipped hairs. 
Distribution. — This squirrel is found in the mountains of Colo- 
rado, and in the Uintah Mountains of Utah, while to the south in 
New Mexico and Arizona it is replaced by several closely allied
