[ Eutamias umbrinus fremonti White ]
Eutamias umbrinus fremonti White, Univ. Kansas Publ., Mus. Nat. Hist. 5:575, December 1, 1953.
Type.—Male, adult, skull, skin, and baculum, No. 41790 (KU); from 31 mi. N Pinedale, 8,025 ft., Sublette County, Wyoming; obtained on July 8, 1951, by Rollin H. Baker; original No. 1596.
Diagnosis.—Size large; over-all tone of upper parts dark; lower tooth-row longest of this species in Wyoming.
Description.—Color pattern: Crown Cinnamon-Buff mixed with gray; upper facial stripe Sepia; ocular stripe Chaetura-Drab; submalar stripe Fuscous Black mixed with Sayal Brown; ears black; anterior margin of ear Mars Yellow; posterior margin of ear grayish white; hairs inside posterior part of pinna Dresden Brown; postauricular patch Pale Smoke Gray; median dorsal dark stripe black; lateral dorsal dark stripes black mixed with Sayal Brown; outermost dorsal dark stripes Buckhorn Brown mixed with black or sometimes absent; median pair of dorsal light stripes grayish mixed with Buckhorn Brown; outer pair of dorsal light stripes creamy white; sides Buckhorn Brown; rump and thighs Pale Smoke Gray mixed with Saccardo's Umber; dorsal surface of tail black mixed with Buckhorn Brown; ventral surface of tail Sayal Brown, with Fuscous Black around margin and white or Light Buff around outermost edge; antipalmar and antiplantar surfaces of feet Warm Buff; underparts creamy white with dark underfur. Skull: Large; zygomata strong and arched; braincase well inflated. Baculum: Broad at base; shaft tapers sharply to tip.
Comparisons.—From E. u. montanus, the subspecies from the Medicine Bow Range of south-central Wyoming, E. u. fremonti differs in: Over-all tone of upper parts darker; underside of tail darker; feet darker; sides darker.
For comparisons with E. u. umbrinus see the account of that subspecies.
Remarks.—This subspecies normally occurs in the forest as do the other subspecies of E. umbrinus in Wyoming. A single specimen taken at 12 mi. N and 3 mi. W Shoshoni, Fremont County, is the exception which probably indicates that E. umbrinus does occur outside of its normal habitat and that gene-flow exists between the subspecies of this species.
