[Illustration: FIG. 51. Probable past distribution of grizzly bears in Washington. A. _Ursus chelan._ B. _Ursus canadensis._ C. _Ursus idahoensis._] The grizzly is the largest carnivorous mammal in North America. From the black bear the grizzly may be distinguished in life by the prominent muscular hump on the shoulders. Another feature is the long, slim, gently curved claws of the forefoot as compared with the shorter, stouter and sharply curved or hooked foreclaws of the black bear. The grizzly is much larger than the black bear. Cranially, the grizzly differs in possessing a larger skull with lower frontal area, higher, more extensive sagittal crest, more posteriorly jutting occipital condyles and much longer tooth row. The color of both species is variable. Some grizzly bears from Alaska and British Columbia are dark brown, almost as black as a black bear. Others are pale cinnamon with the longer guard hairs pale gray. Individuals of this frosted appearance popularly are known as "silver tips." In Washington, the black bear varies in color from glossy black, through various shades of brown to a pale cinnamon. The grizzly bear is extinct over most of Washington. A few may remain in remote parts of the northern Cascades, and are regularly listed on the game census reports of the Mount Baker National Forest. Nevertheless, I have found no one who has seen an undoubted grizzly bear in Washington. The type specimen was obtained well up in the Cascade Mountains where the animals, like those in British Columbia, feed on roots, berries, marmots, pikas and other vegetable and animal life. =Procyon lotor= (Linnaeus) Raccoon _Description._--The raccoon is a relatively large carnivore with a stout, heavy body. Large adults measure three feet in length and weigh up to 20 pounds. The legs are of moderate length. The broad head tapers sharply to a pointed muzzle. The ears are erect, broad, low and rounded; the tail is long, about one-half the length of the head and body, bushy and round; the hind feet are large, flat and naked-soled but the forefeet are smaller with long, slim, handlike toes. The color of the body is a grizzled gray heavily washed with black on the back and sides. A jet-black "mask" across the eyes, sharply outlined by white muzzle and forehead, is the most distinctive feature of the head. The tail is alternately marked with six or seven black and five or six yellowish gray bands. The long, loose guard hairs give the body a shaggy appearance. The fur of the wrists is short, smooth, coarse, and directed downward.
