_Distribution._--Watercourses throughout the state, scarcer east of the Cascades; recorded at Forks (V. B. S.) in the northwest, Puget Island (V. B. S.) in the southwest, Colville (Taylor and Shaw, 1929: 12) in the northeast, and Touchet (Taylor and Shaw, 1929: 12) in the southeast. =Lutra canadensis vancouverensis= Goldman _Lutra vancouverensis_ Goldman, Proc. Biol. Soc. Washington, 48: 186, November 15, 1935. _Type._--Obtained at Quatsino, Vancouver Island, British Columbia, by H. O. Berg in 1905; type in United States National Museum. _Racial characters._--No adults, referred to this race from Washington, have been examined. Said to have broader skull than _pacifica_. _Measurements._--The only available specimen, a young female from Black Rock, San Juan County, measured: total length 792; length of tail 247; hind foot 103; ear 22. _Distribution._--The San Juan Islands of northern Puget Sound and adjacent marine waters. _Remarks._--The otters of the San Juan Islands are referred to this race on geographical grounds. Numerous islands connect Vancouver Island with the San Juan Islands, and intervening channels are not too wide for otters to swim. Adult material may show that the otters of the San Juan Islands are referable to _pacifica_ or to an undescribed race rather than to _vancouverensis_. =Enhydra lutris nereis= (Merriam) Sea otter _Latax lutris nereis_ Merriam, Proc. Biol. Soc. Washington, 17: 159, October 6, 1904. _Enhydra lutris nereis_ Grinnell, Univ. California Publ. Zoöl., 21: 316, January 27, 1923. _Type._--Obtained on San Miguel Island, Santa Barbara Islands, by G. M. McGuire in 1904; type in United States National Museum. _Distribution._--Formerly occurred along the ocean coast of Washington. Now extinct there. _Description._--Adult sea otters reach a length of six feet. The body is stout, long and round; the tail is short, flattened and about a foot in length. The legs are short and thick. The hind feet are webbed for swimming. The head is rounded with small eyes and ears, and a seallike mustache of stiff bristles on the muzzle. The upper lip is thick and heavy, drooping over the sides of the mouth in a spaniel-like fashion. The fur is long, soft and extremely dense. The color of the body is various shades of rich, dark brown. Scattered white hairs often give the coat a frosted appearance. The heads of the adults are pale grey, occasionally almost white. The sea otter once ranged from the Gulf of California north along the west coast of North America to Alaska, the Aleutian Islands, Siberia and Japan. It is now found only in a small area along the coast of California and in remote islands of the north Pacific. Once abundant along the coast of Washington, it is now completely extinct there.
