Eutamias minimus operarius Merriam

_Eutamias amoenus operarius_ Merriam, Proc. Biol. Soc. Washington,
18:164, June 29, 1905.

_Eutamias minimus operarius_, Howell, Jour. Mamm. 3:183, August 4,
1922.

_Type._--Female, adult, skull and skin, No. 129808 (BS); from Gold
Hill, 7,400 ft., Boulder County, Colorado; obtained on October 8,
1903, by Vernon Bailey; original No. 8160.

_Diagnosis._--Size large; general tone of upper parts dark reddish
brown; sides Tawny or Ochraceous Tawny; baculum large, as in _E. m.
pallidus_.

_Description._--_Color pattern_: Crown Cinnamon Buff mixed with
Pale Smoke Gray; facial stripes Fuscous Black mixed with Sayal
Brown; anterior margin of ear and hairs inside posterior part of
pinna Cinnamon Buff; posterior margin of ear and postauricular
patch Pale Smoke Gray; dorsal dark stripes black with Ochraceous
Tawny along margins; median dorsal light stripes Pale Smoke Gray
with Ochraceous Tawny along margins; lateral dorsal light stripes
white; sides Tawny or Ochraceous Tawny; rump and thighs Light
Grayish Olive; dorsal surface of tail Fuscous Black slightly mixed
with Clay Color; ventral surface of tail Sayal Brown or Ochraceous
Tawny with Fuscous Black along margin and Clay Color along
outermost edge; antipalmar and antiplantar surfaces of feet
Ochraceous Buff; underparts grayish white, often washed with Buff.
_Skull_ and _Baculum_: Large but of same proportions as in other
subspecies of _E. minimus_.

_Comparisons._--For comparisons with _E. m. minimus_, _E. m.
pallidus_, _E. m. confinis_, and _E. m. silvaticus_, see the
accounts of those subspecies.

_Remarks._--Specimens from the mountains near Savery in Carbon County
and from near Medicine Bow Peak in Carbon and Albany counties are
clearly referable to this race on the basis of color pattern. However,
in the skull and baculum these specimens resemble _E. m. minimus_.

Specimens from the Laramie Range, 27 mi. N Laramie, show a color
pattern which tends toward that of _E. m. pallidus_.

_Specimens examined._--Total number, 118.
