FIFTH ANNUAL REPORT. 79 
fades out entirely. The posterior edge of the thigh is white. The 
lower portion of the inner surface of the thigh partakes of the gray 
body color, but is somewhat paler. 
On the front edge of the thigh, and extending down to the hoof, 
is a conspicuous band of dark brown, 1% inch wide, which, below 
the hock joint, joins rather abruptly the pure white hair which covers 
the sides and rear edge of the leg. A similar brown band extends 
down the front of the foreleg, from knee to hoof, similarly backed 
up posteriorly with white. 
The tail is similar in color to the body, but much darker, and a 
thin line of dark brown hair connects it with the gray mass of the 
body. The white rump patch is similar in form to that of Ovis mon- 
tana, but covers a smaller area. 
Pelage.—Thick and long; finer and softer than on Ovis montana. On 
the neck and abdomen it inclines to shagginess, like that of the moun- 
tain goat. The stiff, brittle quality is noticeably absent from all white 
parts of the animal. Everywhere the pelage is abundant and thick, 
as befits an Arctic animal. Because of this, the animal appears to be 
shorter in the legs and more stockily built than all other American 
species, save Ovis dalli. 
Length of hair on top of neck, 4% to 5 inches; basal half, stiff, 
crimped; terminal half, fine, straight, rather soft. One inch 
of thin, fine wool next to skin. 
Length of hair on throat and lower neck, 3% inches. 
Length of hair on middle of side, 2% to 3 inches; fully crimped, 
stiff ; trace of fine wool at base. 
Length of hair on inner surface of thigh, 3 inches; straight, fine, 
rather soft. 
Length of hair on abdomen, 2% inches; rather fine and straight. 
pee of hair on tail, upper surface, 3 inches; straight, coarse, 
stiff. 
Horns.—In color, clear, transparent, even amber-like, similar to the horns 
of Ovis dalli when clean. Annulations numerous and well defined. 
A slight groove under the superior angle, not so deep as that of Ovis 
stonet. In the type specimen the horns do not spread as in Ovis stonei 
and dalli; but this character is of little scientific value, because of the 
wide variations between individuals of the same species.
