_Description._--_Color pattern_: Crown Pale Smoke Gray mixed with Clay Color; facial stripes Fuscous Black mixed with Clay Color; anterior margin of ear and hairs inside posterior part of pinna Pale Pinkish Buff; posterior margin of ear and postauricular patch grayish white; median dorsal dark stripe black with Clay Color along margins; other dorsal dark stripes Fuscous mixed with Clay Color; median pair of dorsal light stripes Pale Smoke Gray; lateral pair of dorsal light stripes creamy white; sides Cinnamon Buff; rump and thighs Smoke Gray mixed with Pale Buff; dorsal surface of tail Fuscous Black slightly mixed with Warm Buff; ventral surface of tail Pinkish Cinnamon or Pinkish Buff, with Fuscous Black along margin and Warm Buff along outermost edge; antipalmar and antiplantar surfaces of feet Pinkish Buff, Warm Buff or Pale Yellow-Orange; underparts white with dark underfur. _Skull_ and _Baculum_: Large but of same proportions as in other subspecies of _E. minimus_. _Comparisons._--From _E. m. silvaticus_, the subspecies from the Black Hills, _E. m. pallidus_ differs in: Paler; underside of tail paler; sides paler. From _E. m. confinis_, the subspecies from the Big Horn Mountains, _E. m. pallidus_ differs in: Over-all tone of upper parts paler; sides paler; underside of tail paler. From _E. m. operarius_, the subspecies from the mountains in south-central Wyoming, _E. m. pallidus_ differs in: Over-all tone of upper parts paler; sides paler; underside of tail paler. For comparisons with _E. m. minimus_ and _E. m. consobrinus_, see the accounts of those subspecies. _Remarks._--Specimens from near Buffalo, Johnson Co., are intergrades between _E. m. pallidus_ and _E. m. confinis_ and are referable to _E. m. confinis_. Specimens from near Sundance (not in Bear Lodge Mountains), Crook Co., are intergrades between _E. m. pallidus_ and _E. m. silvaticus_ (Howell 1929:55). Specimens from the Laramie Range in Converse Co. are intergrades between _E. m. pallidus_ and _E. m. operarius_, and referable to _E. m. operarius_. Specimens from near Greybull, Big Horn Co., are intergrades between _E. m. pallidus_ and _E. m. minimus_ and are referable to _E. m. pallidus_. These specimens show no intergradation with _E. m. confinis_ which occurs but a short distance to the east in the Big Horn Mountains. Intergradation between _E. m. pallidus_ and _E. m. minimus_ probably exists in northeastern Natrona Co. and southwestern Johnson Co. Comparisons of specimens of _E. m. pallidus_ and _E. m. cacodemus_, indicates that, in my opinion, _E. m. cacodemus_ is entitled to subspecific recognition, for, the relationship between _E. m. pallidus_ to _E. m. cacodemus_ is the same as that between _E. m. pallidus_ and _E. m. confinis_. _Specimens examined._--Total number, 58. _Park Co._: 2 mi. S and 2 mi. E Meteetse, 5,750 ft., 3.
