Zygogeomys trichopus tarascensis Goldman
Michoacán Pocket Gopher; Spanish, Tuza de Michoacán; Tarascan, Cúmu (Cŏmŏ)
Zygogeomys trichopus tarascensis Goldman, Proc. Biol. Soc. Washington, 51:211, December 23, 1938, type from six miles southeast of Pátzcuaro, 8,000 ft., Michoacán.
Zygogeomys trichopus Merriam, N. Amer. Fauna, 8:196, January 31, 1895.
Range.—"Known only from the upper slopes of the mountains in the vicinity of the type locality" (Goldman, 1938:211).
Remarks.—As we drove an automobile from Pátzcuaro to Tacámbaro we noted mounds made by pocket gophers along the road in the highest part of the pass and supposed that these mounds were made by Zygogeomys although we took no specimens of any kind of pocket gopher in the pass.
