was said to be common there at that season, but as I was travel- 

 ing in boats to the interior, had but little time to search for it. 

 I know but little of its habits. It becomes excessively fat, and is 

 eaten by the Indians. Disappears in August, and emerges in the 

 spring in a very attenuated state. — Towns, in lit. 



Douglass' Squirrel. 



Sciurus Douglassii, (Bennett.) Sciurus Townsendii, (Bach- 

 man.) Journal Acad. Nat. Sciences, Vol. 8, part I. Ap-poe- 

 poe, of the Chinook Indians. 



"This species, in the form of its body, is not very unlike the 

 Sciurus hndsonicus ; its ears and tail, however, are proportion- 

 ably much shorter ; it is about a fourth larger, and in its mark- 

 ings differs widely from all other known species. 



Head considerably broader than that of the Sciurus hudsonicus; 

 nose less elongated and blunter, body long and slender ; ears 

 rather small, nearly rounded, slightly tufted posteriorly. As 

 usual in this genus, the third inner toe is the longest, and not the 

 second, as in the Spermophile. 



Color. — The whiskers, which are the length of the head, are 

 black. The fur, which is soft and lustrous, is, on the back from 

 the roots to near the points, plumbeous, tipped with brownish- 

 gray, with a few lighter colored hairs interspersed, giving it a 

 dark brown appearance ; when closely examined, it has the ap- 

 pearance of being thickly sprinkled with minute points of rust 

 color on a black ground. The tail, which is distichous, but not 

 broad, is, for three-fourths of an inch, of the color of the back ; in 

 the middle, the fur is plumbeous at the roots, then irregular 

 markings of brown and black, tipped with soiled white, giving it 

 a hoary appearance ; on the extremity of the tail, the hairs are 

 black from the roots, tipped with light brown. The inner sides 

 of the extremities, and the outer surface of the feet, together with 

 the throat and mouth, and a line above and under the eye, are 

 bright buff. The colors on the upper and under parts are sepa- 

 rated by a line of black, commencing at the shoulders, and run- 

 ning along the flanks to the thighs. It is widest in the middle, 

 about three lines, and tapers off to a point. The hairs which 

 project beyond the outer margins of the ears, and forming a 

 slight tuft, are dark brown, and, in some specimens, black.
