A male of the second year, bearing horns with a single fork 

 near the end (No. r¥r%> Am - ^ lus - ^ :lt - Hist.; No. 159, Mearns's 



collection), killed near the base of Bill 

 | Williams Mountain, Arizona, December 

 5, 1884, is in complete winter pelage. 

 It is in the shaggy pelage of bluish 

 gray or pepper-and-salt, which hunt- 

 ers call the "blue" coat, the color 

 being quite similar to that of the mule 

 deer at the same season. Upper parts 

 ash plumbeous, grizzled with gray and 

 black, with a very slight rusty tint 

 posteriorly and along the sides. The 

 individual hairs are very pale drab at 

 base, shading to plumbeous, then annu- 

 lated with grayish white and pointed 

 with black.' As in the mule deer, the 

 color is darkest along the middle of the 

 back, where the black points are widest, 

 growing paler laterally as the black 

 points are gradually reduced in width 

 and finally become obsolete. The pelage 

 is much finer and more furry than that of the mule deer, and the griz- 

 zling correspondingly finer. Upon the head the grayish-white annuli 

 are sharper and broader than, elsewhere, notwithstanding which the 

 face has a blackish aspect, which is heightened by a black V-shaped 

 mark between the eyes, formed by two stripes beginning, one on 

 either side, about L3 mm. internal to the inner canthus of the eye. 

 and converging forward to meet in the median line at the base 

 • if the nasal bones. The naked" muffle is separated from three black 

 triangular areas — one above and two lateral — by a narrow band of 

 white which also encircles the nostrils. Upon the upper border of
