APPENDIX C 339 



On the front edge of the thigh, and extending down to the hoof, 

 is a conspicuous band of dark brown, one and one-half inches 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 montana, 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 

 mountain 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. 



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 stonei. In the type specimen the horns do not spread as in 

 Ovis stonei and dalli; but this character is of little scientific value, be- 

 cause of the wide variations between individuals of the same species.
