Citellus parryii plesius (Osgood) Parry Ground Squirrel _Spermophilis empetra plesius_ Osgood, N. Amer. Fauna, 19:29, October 6, 1900. (Type from Bennett City, head of Lake Bennett, British Columbia.) _Citellus paryii plesius_ A. H. Howell, N. Amer. Fauna, 56:97, May 18, 1938. _Specimens examined._--Total 42, as follows: _Alaska_: Richardson Highway, 2000 ft., 32 mi. S and 4 mi. W Big Delta, 5. _Yukon Territory_: 6 mi. SW Kluane, 2550 ft., 1; McIntyre Creek, 2250 ft., 3 mi. NW Whitehorse, 1; 2 mi. NNW Whitehorse, 2100 ft., 1; 1 mi. NE Whitehorse, 1; ½ mi. W Whitehorse, 2150 ft., 1; SW end Dezadeash Lake, 1; 2 mi. W Teslin River, 2400 ft., 16 mi. S and 56 mi. E Whitehorse, 7; 1½ mi. E Tatshenshini River, 1½ mi. S and 3 mi. E Dalton Post, 3. _British Columbia_: Stonehouse Creek, 5½ mi. W jct. Stonehouse Creek and Kelsall River, 14; W side Mt. Glave, 4000 ft., 14 mi. S and 2 mi. E Kelsall Lake, 7. _Remarks._--The specimens vary much in color; most color variation is the result of wear and fading. In pallor of coloration the specimens taken on August 16 along the Richardson Highway, 32 miles south and 4 miles west of Big Delta, Alaska, show some resemblance to _C. p. ablusus_, which occurs to the westward, although in other diagnostic characters these specimens are typically _C. p. plesius_. Specimens in early stages of molt were taken on July 3, 4, and 14; another specimen in an advanced stage of molt was obtained on July 10. One melanistic individual was taken one mile northeast of Whitehorse on July 11. Alcorn found these ground squirrels locally abundant, especially in the vicinity of Whitehorse in Yukon Territory. A large population was observed along the highway west of the Teslin River; animals were seen for several miles along the road, principally in open coniferous forests where there was little or no underbrush. Alcorn caught several animals near the city dump at Whitehorse. Along the Richardson Highway he observed these ground squirrels almost continuously for approximately ten miles. He comments that the animals appeared to be more numerous in the man-cleared areas along the highway than in "unmolested areas farther back from the highway." Specimens were taken with collecting gun and in rat traps baited with "chewed" rolled oats. Eutamias minimus borealis (J. A. Allen) Least Chipmunk _Tamias asiaticus borealis_ J. A. Allen, Monogr. N.
