220 U. S. P. R. R. EXP. AND SURVEYS ZOOLOGY GENERAL REPORT. 



inch. The hind foot is rather shorter than the fore feet ; the proportions of the toes very similar 

 to those of the fingers, the claws much shorter, or little over one inch. The halls of the toes 

 are longer than wide ; the outer the larger, and advancing nearly as far as the fourth or longest. 

 The single pad on the sole is longer than wide, and somewhat shield-shaped. 



A much larger specimen in Dr. Newberry's collection agrees in general characters, except 

 that the tail is still shorter in proportion to the ear. The longest fore claw measures four 

 inches. The sole of the hind foot is rather longer than in the young ; the single large pad 

 measuring ahout seven and a half inches by five. 



The grizzly hears of the Pacific coast vary somewhat in tint, hut maintain at the same time 

 quite constant characters. Thus the limbs are generally black or dark brown ; there is a dark 

 stripe along the back, commencing at the occiput, and another on each flank parallel to this, 

 and commencing behind the axillae. The sides of the body, on either side of the dorsal stripe, 

 are of a pale brownish yellow, with a tinge of hoary, and brighest over the shoulders, the 

 general effect being curiously similar to what is seen in Spermophilus douglafisii, and to a less 

 extent in S. beecheyi; the distinctness of the stripe is, however, obscured by the hairs being all 

 tipped with lighter. The belly is of a dull yellowish, as is also the head generally, which, 

 however, occasionally, is brownish in part. There is, generally, a suffusion of brown about the 

 ears. 



There is a kind of mane on the neck, extending from the occiput to the shoulders, along 

 which the hair :'s considerably longer than that on either side, especially in the adult. In the 

 largest specimen before me these hairs of the mane are five inches long, the others only three ; 

 they are dark reddish brown at the base, shading into black to near the tip, which is pale 

 brownish yellow. The lighter colored spaces on either side of this line are brownish ashy at 

 the base. The remaining and largest portion dirty yellowish. The head above and sides of 

 the neck are yellowish, the under surface of the body of a duller tint of the same. The limbs 

 generally are blackish, with occasional tips of the dirty yellow. 



In one young animal the legs are dusky, and the entire body at first sight appears of a dirty 

 yellowish. On closer examination, however, the concealed darker dorsal stripe, and those on 

 the flanks can be readily made out, more of the tips of the hairs generally being invaded by 

 the yellowish. 



Other still younger specimens are darker and exhibit the three longitudinal stripes very 

 distinctly. 



The largest skin of this grizzly, from California, measures 6 feet in length. From six to 

 seven feet may be considered the maximum. 



A very large specimen (2039) from the Yellowstone is nearly uniform in its colors in all 

 parts, the body of the hairs being dark brown, the ends of the hairs dull brownish yellow. It 

 measures about six feet to the tail which is a mere rudiment shorter than the ears. 



Another specimen, (1843,) on the contrary, is much varied, the prevailing color being cinna 

 mon brown, more yellow on the nose, flanks, and lower part of the back ; the legs nearly uniform 

 dark reddish brown. The darker hairs of the back are brownish yellow at the base, then 

 cinnamon, and finally tipped with lighter. This specimen measures 6 feet. 



A young animal, (1826, dressed skin,) is entirely of a whitish yellow above and on the sides, 

 anteriorly. Another, (1830,) is almost a miniature of No. 2039, except that a dorsal dark 

 line separates the lighter of the sides. There is, however, a distinct crescentic white patch on 

 the side of the shoulder or a little anterior to it.
