The average size of the chipmunk is about as follows: Total 
length, 9.75 in. (250 mm.); length of tail, 4 in. (100 mm.); hind foot, 
1.4 in. (36 mm.). 
The color of specimens taken in Champaign county is as follows: 
Hair on chin, throat, belly, and inside of legs creamy white, faintly 
flushed with buff near the borders. In a small spot behind the ears 
the hair is dirty white throughout its length. A streak below the 
eye and one above are buff to the base. The hairs on the under 
side of the tail are entirely chestnut. On all the other parts the 
hairs are all plumbeous at base. Over the side of the body the dark 
base of the hairs is followed by a broad band of buff with usually a 
minute tip of black, a few of the hairs having broad black tips. Over 
the rump, the outside of the hind legs, the top of the head, the front of 
the ears, and in a stripe back of the eye the buff is largely replaced 
by chestnut or bay. On each side of the body there is a light 
stripe extending from shoulder to rump. Here few of the hairs 
have black tips, but, instead, very light buff or creamy white ones. 
Each side of the light line is a dark one, all the hairs of which are 
black-tipped. These dark lines are each obscurely banded with a 
slender line of hairs tipped with chestnut. There is a vertebral line 
of black-tipped hairs bordered with chestnut-tipped ones, these 
being continued forward as a faint line which is lost in the chestnut 
of the top of the head. In the space between the vertebral line and 
the series of light and dark lines on each side, the hairs are annulated 
with black and white or light buff, the general effect being a dark 
gray. The hairs on the upper surface of the tail are banded with 
plumbeous, chestnut, and black, with a tip of light buff, the general 
effect being a brownish gray. 
The incisor teeth are pale chestnut. The palms are naked and 
white. The soles of the hind feet are hairy and dark gray. 
Chipmunks are not found in the open prairie and are but seldom 
seen in closely pastured woodland or in prairie groves. The wooded 
bluffs,and the bottoms down to the usual high-water mark, are their 
common habitat. They are not often found in the deeper woods, 
but rather along the edge of the bluff woods, where the trees have 
been thinned out but where there is still an abundance of old logs, 
bushes, and brush-heaps. Where the proper conditions exist they 
are quite numerous, but over a large part of the county they are rare 
or entirely wanting.
