dark brown, commencing at the termination of the nose, where 

 it forms a point, and bordering the fawn color above, is gradually 

 blended with the lighter colors of the head. The ears, which 

 are of moderate size, and ovate, are on the upper margins of the 

 inner surface partially clothed with a few short, brown hairs ; 

 the outer surface is thickly clothed with fur, brown on the ante- 

 rior parts, with a patch of white covering about one-fourth of the 

 ear on the posterior portion. Behind the ear there is a slight 

 marking of cinereous, of about six lines in length, terminating near 

 the shoulder. A line of black commences on the hind part of 

 the head, runs over the centre of the back, where it spreads out 

 to the width of four lines, and terminates in a point at the inser- 

 tion of the tail ; a line of similar color commences at the shoul- 

 ders, and running parallel, terminates a little beyond the hips; 

 another, but narrower and shorter line of the same color, runs 

 parallel with this, low down on the sides, giving it five black 

 stripes. The head and back are light yellowish-brown, present- 

 ing on the upper surface a dusky ochre color. It has not the 

 whitish stripes on the sides, nor the rufous color on the hips, 

 which are so conspicuous in the Sciurus (Tamias) lysteri. On 

 the throat, belly, and inner parts of the legs and thighs, the color 

 is light cinereous ; there is no line of separation between the co- 

 lors of the back and belly. The tail, which is not bushy, is on 

 the upper surface grayish-black, having a hoary appearance. 

 Underneath it is reddish brown, for two-thirds of its breadth, then 

 a narrow line of black, tipped with light ash. The nails are 

 brown.

This pretty little animal, so much resembling our common 

 striatus, is quite common on the Columbia river. It lives in 

 holes in the ground, and is so tame, that it not unfrequently runs 

 over your feet as you traverse the forests. It frequently perches 

 itself upon a log or stump, and keeps up a continual clucking,
