Geographic Distribution and Taxonomy of the Chipmunks of Wyoming
shorter and shallower; baculum shorter; slightly paler.
From E. m. confinis, the subspecies in the Big Horn Mountains, E. m. minimus differs in: Size smaller; skull shorter and narrower; mandible shorter and shallower; baculum shorter; paler.
From E. m. operarius, the subspecies to the east and southeast, E. m. minimus differs in: Size smaller; skull shorter and narrower; mandible shorter and shallower; baculum shorter; paler.
Remarks.—E. m. minimus is the smallest of the chipmunks that occur in Wyoming. This pale little squirrel is found in the Red Desert in Sweetwater County, where the features distinctive of the subspecies are most strongly developed. Specimens from western Sweetwater County and northwestern Uinta County are intergrades between E. m. minimus and E. m. consobrinus and are referable to E. m. minimus.

Eutamias lectus J. A. Allen, Brooklyn Inst. Mus. Sci. Bull. 1:117, March 31, 1905 (not in Wyoming), type from Beaver Valley, Utah.
Eutamias consobrinus clarus Bailey, Proc. Biol. Soc. Washington, 31:31, May 16, 1918, type from Swan Lake Valley, Yellowstone National Park, Wyoming.
Type.—Male, adult, skull and skin, No. 186456 (NM); from near Barclay, Parley's Canyon, Wasatch Mountains, Salt Lake County, Utah; obtained on October 31, 1888, by Vernon Bailey; original No. 361.
Diagnosis.—Size small; over-all tone of upper parts grayish brown; baculum small, as in E. m. minimus.
Description.—Color pattern: Crown Smoke Gray mixed with Ochraceous-Tawny; upper facial stripe Fuscous; other facial stripes Fuscous or Fuscous Black mixed with Tawny; hairs inside posterior part of pinna Light Ochraceous-Buff; anterior margin of ear Ochraceous-Tawny; posterior margin of ear and postauricular patch grayish white; median dorsal dark stripe black with Ochraceous-Tawny along margins; other dorsal dark stripes black mixed with Ochraceous-Tawny; median pair of dorsal light stripes grayish white with Ochraceous-Tawny along margins; lateral pair of light dorsal stripes white; sides Ochraceous-Tawny or Light Sayal Brown; rump and thighs Smoke Gray mixed with Cinnamon-Buff; dorsal surface of tail Fuscous Black mixed with Cinnamon-Buff; ventral surface of tail Sayal Brown, Fuscous Black along margin, and Cinnamon-Buff or Ochraceous-Buff along outermost edge; antipalmar and antiplantar surfaces of feet Light Pinkish Cinnamon or Pinkish Buff; underparts grayish white mixed slightly with Buff. Skull and Baculum: Small but proportionally the same as in other subspecies of E. minimus.
Comparisons.—From E. m. pallidus, the subspecies to the east, E. m. consobrinus differs in: Color darker; size smaller; skull narrower and shorter; baculum shorter.
From E. m. confinis, the subspecies from the Big Horn Mountains, E. m. consobrinus differs in: Over-all tone of upper parts less grayish; underside of tail lighter; skull narrower and shorter; baculum shorter.
For comparisons with E. m. minimus see the account of that subspecies.
Remarks.—Specimens of this subspecies from the area between the Uinta Mountains and the mountains of the Wyoming and Wind River ranges, are clearly intergrades between E. m. consobrinus and E. m. minimus and are here referred to E. m. consobrinus. These specimens are paler than typical E. m. consobrinus and considerably darker than E. m. minimus. These intergrades came from an area where the habitat is intermediate between that of E. m. consobrinus and E. m. minimus but more nearly like that of E. m. consobrinus.
