_Remarks._--This subspecies is transitional between the large, usually dark subspecies of the southeastern Alaskan and British Columbian coast and islands, and the smaller, paler subspecies of western and interior Alaska. There seem to be no sharp breaks between _alascensis_ and _shumaginesis_. North of Haines, Alaska, size of shrews decreases in a short distance across a narrow intergradational zone between _alascensis_ and _obscurus_. Throughout most of its range _S. v. alascensis_ occurs with _Sorex cinereus_.
