Clethrionomys gapperi uintaensis Doutt
1897. Evotomys gapperi galei, Bailey, Proc. Biol. Soc. Washington, 11:127 (part from Uinta Mts. of Wyoming), May 13.
1941. Clethrionomys gapperi uintaensis Doutt, Proc. Biol. Soc. Washington, 54:161, Dec. 8.
Type locality.--Paradise Park, 10,050 feet, 45 miles by road northwest Vernal, Uintah County, Utah.
Range.--The Uinta Mountains of northern Utah and southwestern Wyoming.
Remarks.--From the description given by Doutt (Proc. Biol. Soc. Washington, 54:161, 1941) in his original description of this subspecies, it appears that he had available for comparisons, only subadult specimens of C. g. galei. As judged from the material of C. g. uintaensis available to us (1 topotype, KU 38081, and 7 specimens from Uinta County, Wyoming, listed below) and from Doutt's (op. cit.) description and measurements, the subspecies C. g. uintaensis is but weakly differentiated from C. g. galei. No marked cranial differences are evident between the two subspecies; the differences in pelage noted by Doutt (op. cit.:161), however ("Similar to Clethrionomys gapperi galei from Ward, Colorado, but head and cheeks grayer; sides and back paler; belly whiter."), do seem to be valid.
