_Sorex personatus streatori_ Merriam, N. Amer. Fauna, 10:62, December 31, 1895. (Type from Yakutat, Alaska.)
_Sorex cinereus streatori_ Jackson, Jour. Mamm., 6:56, February 9, 1925.
_Specimens examined._--Total 19, as follows: _Alaska_: E side Chilkat River, 100 ft., 9 mi. W and 4 mi. N Haines, 10; 1 mi. S Haines, 5 ft., 9.
_Remarks._--Average and extreme external measurements of the nine adult specimens from 1 mile south of Haines are as follows: Total length, 103 (98-105); tail, 45 (43-46); and condylobasal length, 16.2 (16.0-16.4). Corresponding measurements of an adult specimen (No. 1676, UKMNH) from Sitka, Alaska, are 108, 47, and 16.5. Measurements of ten adult specimens from the Chilkat River, 9 miles west and 4 miles north of Haines, are 100 (91-106), 44 (40-50), 16.0 (15.5-16.5). The slightly smaller average size of the latter specimens indicates a trend toward the smaller _S. c. cinereus_, which occurs farther inland. Skulls of some of the specimens from the Chilkat River have a more slender rostrum than those of the specimens from 1 mile south of Haines, and more nearly resemble _S. c. cinereus_ in this respect. Evidently, as indicated by Jackson (1928:54), _S. c. streatori_ occupies only an extremely narrow strip of mainland in the vicinity of Haines.
_Sorex cinereus hollisteri_ Jackson, Jour. Mamm., 6:55, February 9, 1925. (Type from St. Michael, Alaska.)
_Specimens examined._--Two from _Alaska_: 1 mi. NE Anchorage, 100 ft.
_Remarks._--Both specimens of this pale subspecies were trapped, along with six _Clethrionomys_ and one _Mus_, in a grassy area bordered on one side by the road and on the other by a spruce forest. No. 21069, [male]?, taken on August 21, is in molt, with one patch of new fur on the rump and another along the midline of the nape and shoulders.
_Sorex obscurus_ Merriam, N. Amer. Fauna, 10:72, December 31, 1895. (Type from near Timber Creek, altitude 8200 ft., Salmon River Mountains, now Lemhi Mountains, 10 miles west of Junction, Lemhi County, Idaho.)
_Specimens examined._--Total 12, as follows: _Yukon Territory_: McIntyre Creek, 2250 ft., 3 mi. NW Whitehorse, 1; SW end Dezadeash Lake, 2; 1½ mi. S and 3 mi. E Dalton Post, 2500 ft., 1. _British Columbia_: Stonehouse Creek, 5½ mi. W jct. Stonehouse Creek and Kelsall River, 4; W side Mt. Glave, 4000 ft., 14 mi. S and 2 mi. E Kelsall Lake, 1; Hot Springs, 3 mi. WNW jct. Trout River and Liard River, 1. _Alberta_: Assineau River, 1920 ft., 10 mi. E and 1 mi. N Kinuso, 2.
