Abstract:

Howell, in his revision of the North American ground squirrels, arrived at several conclusions concerning the distribution and differentiation of Townsend ground squirrels in Idaho with which my independent study does not agree. These are (1) that Citellus idahoensis is a distinct species, (2) that Citellus townsendii mollis occurs north of the Snake River, and (3) that C. t. vigilis is restricted to Oregon. The purpose of this paper is to report on my study of these squirrels in Idaho during the years 1934 to 1937, particularly their distribution and relationships.
