_Remarks._--Specimens from Washington are intermediate in character between _luteus_ and the race inhabiting British Columbia, although available skulls are closer to _luteus_.

(Fish and Wildlife Service photo by Victor B. Scheffer, No. 76.)] _Description._--Large males measure more than three feet in length, of which the tail makes up 10 inches; they weigh as much as 50 pounds (Grinnell, Dixon and Linsdale, 1937: 253). The body is wide and stocky; the tail is short; the legs, especially the forelegs, are short, thick and powerful; the feet are large and are armed with long, curved claws; the head is wide; the jaws are powerful with heavy teeth. The pelage is long and rather shaggy. Face, legs, back and terminal portion of the tail are dark, blackish brown but the forehead is grayish, contrasting with the dark color of face and top of the head. Two broad, yellowish-brown bands begin on the side of the shoulders and pass back, low on the sides, to the hips where they join across the back and base of the tail. The wolverines, nominally of several species, form a compact group that ranges over the boreal regions of the Old and New world. In North America they range southward from the Arctic to California and Colorado. [Illustration: FIG. 60. Wolverine (_Gulo luscus_), male, trapped by Reuben R. Lamb, March 22, 1941, three miles south of Riverside, Washington; reported to weigh 40 pounds; dried pelt 3 × 4 feet. (Reuben R. Lamb photo.)] [Illustration: FIG. 61. Distribution of the wolverine, _Gulo luscus luteus_, in Washington.] The wolverine is adapted to boreal conditions and is most abundant in the arctic. In the Cascades it occurs only at or near timber-line. Except the wolf and the possibly extinct grizzly bear, the wolverine is the rarest carnivore in Washington. Probably it has been rare since the retreat of the continental glaciers, for suitable habitat for wolverines is not abundant and each animal requires a large area over which to range. An unusual record, possibly of a wandering animal, is given by Scheffer (1941: 37). This is of an adult male taken in the Okanogan Valley 3 miles south of Riverside, Okanogan County, on March 22, 1941. =Lutra canadensis= (Schreber) River otter
