Red Squirrel
Sciurus hudsonicus petulans Osgood, N. Amer. Fauna, 19:27, October 6, 1900. (Type from Glacier, White Pass, Alaska.)
T[amiasciurus]. hudsonicus petulans A. H. Howell, Proc. Biol. Soc. Washington, 49:136, August 22, 1936.
Specimens examined.—Total 7, as follows: Alaska: 1 mi. S Haines, 5 ft., 2. Yukon Territory: SW end Dezadeash Lake, 1; 1½ mi. E Tatshenshini River, 1½mi. S and 3 mi. E Dalton Post, 4.
Remarks.—Specimens from extreme southwestern Yukon Territory appear to be referable to this subspecies. The one adult female (skull only, with body measurements) from the southwestern end of Dezadeash Lake has a shorter skull than does any adult female of T. h. columbiensis. No skins of adults are in the series, but the skins of three subadults have darker upper parts, a darker tail and less olivaceous sides than T. h. columbiensis.
