Mamm., 2:161, August 19, 1921. _Type._--Adult male, skin and skull; No. 56561, U. S. Biol. Surv. Coll.; obtained on October 3, 1893, by J. E. McLellan from Thurmans Camp, Bluff Lake, 7500 ft., San Bernardino Mts., California. _Range._--Confined, so far as known, to the San Bernardino and San Gabriel mountains, San Bernardino Co., California. _Diagnosis._--Size medium for the species; measurements of two specimens from the San Bernardino Mountains are: total length, 105, 106; tail, 41, 48; hind foot, 12, 14. Upper parts in summer Olive-Brown to Buffy-Brown; cranium flattened and relatively narrow; unicuspids and incisors relatively small. _Comparisons._--For comparison with _S. v. obscuroides_, the only adjacent subspecies, see the account of that subspecies. _Remarks._--_S. v. parvidens_ is seemingly an uncommon mammal. I have been informed by Terry Vaughan that repeated attempts by him to obtain it in suitable habitat in the San Gabriel Mountains failed. This shrew is probably no longer in reproductive continuity with _Sorex vagrans_ of the Sierra Nevada. _Specimens examined._--Total number, 4.
