The specimens of the above squirrel exhibit scarcely any 

 variations in colour ; they were procured by Mr. Townsend 

 on the Columbia river. He remarks in his notes, — " This 

 is a very plentiful species, inhabits the pine trees in this neigh- 

 bourhood, and, like our common Carolina, lays in a great 

 quantity of food for consumption during the winter months. 

 This food consists of the cones of the pine, with a few acorns. 

 Late in autumn it may be seen very busy in the tops of the 

 trees, throwing down its winter stock ; after which, assisted 

 by its mate, it gathers in and stows away its store, in readi- 

 ness for its long incarceration."

Characters — A third smaller than the Northern Grey Squirrel ; tail 

 shorter than the body ; ears slightly tufted ; colour reddish above, white 

 beneath. Dental formula ; Incisors, § ; Canines, gg ; Molars, $ *> — 20. 



In the number and arrangement of the teeth there is a great 

 resemblance between this species and the Townsend's squir- 

 rel. The present species also, being well known and having 

 been frequently described, a short description in this place is 

 merely added for convenient reference. 



Forehead slightly arched ; whiskers longer than the head, 

 black ; nose rather obtuse ; ears somewhat concave, rounded, 

 clothed with hair ; that which covers the outer surface, dur- 

 ing winter extends three or four lines beyond the margins ; 

 tail clothed with long hairs, but not bushy as in the larger 

 species.
