Width of the postorbital process at base.—The postorbital process is broader at the base in the subgenus Eutamias and in the genus Tamias than in most species of the subgenus Neotamias. Genera and Subgenera of Chipmunks

In E. townsendii, however, this process is relatively as broad as in the subgenus Eutamias and in the genus Tamias. Genera and Subgenera of Chipmunks
