APPENDIX C 337 



collected by Mr. Stone on the headwaters of the Stickeen River, 

 British Northwest Territory, near the Alaskan boundary, at an altitude 

 of about six thousand five hundred feet. The species may be described 

 as follows: 



Ovts stonei, sf>. nov. 



Male Adult. Above gray, formed by an intimate mixture of whitish 

 and blackish brown; face, ears, and sides of neck lighter and more 

 whitish, being much less varied with blackish brown; whole posterior 

 area and lower parts from hinder part of back downward and forward, 

 covering the posterior aspect of thighs, and the abdomen, white, the 

 white area narrowing anteriorly and terminating in a V-shaped point 

 on the middle of the chest; also a broad, sharply defined band of white 

 on the posterior surface of both fore and hind limbs, extending from 

 the body to the hoofs, and proximally including also the inner surface; 

 front of neck, from base of lower jaw posteriorly to the white of the 

 ventral surface, including the breast and greater part of the chest, and 

 thence along the sides to the thighs, nearly black; the lateral extension 

 along the flanks becomes narrower posteriorly, and the neck is some- 

 what grizzled with white; outer surface of both fore and hind limbs black- 

 ish brown, either uniform or in some specimens varied with a slight 

 mixture of whitish; back of head with a broad area of black, narrow- 

 ing posteriorly and continuing to the tail as a well-defined blackish 

 dorsal stripe; tail wholly deep black, except a few white hairs on the 

 middle of its lower surface; a narrow blackish chin bar, varying in 

 breadth and distinctness in different individuals; hoofs black; horns 

 light brown. 



This species is based on three males, of the ages, respectively, of 

 two, five, and six years. The older specimen is taken as the type. 

 On this the dark areas are blacker, and on some parts less varied with 

 whitish tipped hairs than in the others, especially the two-year-old. 



This species differs from Ovis dalll in the prevailing coloration, 

 being either dark gray or blackish brown, according to the area in 

 question, instead of being "a nearly uniform dirty-white color." In 

 O. stonei the white is restricted to definite, sharply defined areas, in 

 strong contrast with the adjoining parts. 0. stonei and 0. dalli ap- 

 parently agree in size and in the character of the horns.
