Description. — Adult female (type, killed June !>) 

 in summer pelage: Similar in form to the black- 

 tailed deer of the Columbia River (Odocoileus co- 

 Itimbianus), but much paler and probably smaller, 

 •with larger ears. Color reddish fawn, darker 

 from black annulations on the hack, lightening to 

 grayish cinnamon on the sides, and grayish drab on 

 the neck. The legs are cream-buff, except where 

 new clay-colored hair is coming in on the anterior 

 border, the limits being almost the last part to re- 

 ceive the summer coating. The coloring of the 

 head is very similar to that of the nude deer in 

 corresponding pelage. It has the horseshoe or 

 arrow-mark on the forehead, and other dark 

 markings of the head to correspond; and the ears J 

 are relatively almost or quite as large, and as scant-

metatarsal gland (fig. 16), which agrees in size and 

 location with that of Odocoileus columbianus (Richardson), is sooty 

 at the base, and white apically. The tail (fig. 17) is colored much 

 as in 0. columbianus ,but has a longer terminal switch ; uppersideand 

 extremity of tail all black. lower side white ntesially.and naked toward 

 the base. The pelage of this deer is short and coarse in comparison 

 with that of the white-tailed deer of Virginia or the black-tailed deer 

 of the Columbia River region, and, as would naturally be expected, is 

 not so red as that of the latter. The type contained a fetus the size 

 of a cotton-tail rabbit. The dimensions of this individual, meas-
