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.
