and inside of hind legs white, the white on the legs decreasing in width 

 distally and terminating a little below the tarsal joint; outside of 

 hind legs proximally like the body, becoming ochraceous brown below 

 the tarsal joint and deepening in color distally to deep ochraceous on 

 the feet; tarsal gland dark rusty brown or dull chestnut, usually with 

 a blackish tinge; ears externally gray, passing into pale buff basally, 

 and white internally, with a slight fringe of buff; tail above at base 

 like the rump, passing gradually into black, which occupies from about 

 one-half to two-thirds its length; lower side of tail white, the white 

 also forming a terminal fringe visible from above. Antlers dark red- 

 dish brown; they are small, but very symmetrical and handsome in 

 the old males. 



The foregoing is based on a middle-aged male in prime con- 

 dition, but the coloration in the series of fourteen specimens, 

 including females and young males, is so uniform that the 

 variations are hardly worth noting, and are fairly covered by 

 the qualifications above expressed. They relate mainly to 

 the distinctness of the black face and chin marks, the extent 

 of the black area on the tail, the intensity of the fulvous tints 

 on the legs, and the dusky shading on the pectoral area, which 

 is sometimes quite blackish. In the adult males there is also 

 very little variation in size, either in external measurements 

 or in the skulls, as shown by the following: 



External measurements of 3 adult males: Total length, 

 1508 (1500-1524); tail vertebra, 127 (127-127); hind foot, 

 436 (432-438); height at shoulders, 902 (889-908). A fourth 

 adult male measures slightly smaller. The two adult females 

 are much smaller, except that the tail is much longer, as fol- 

 lows, respectively: Total length, 1321, 1283; tail vertebrae, 

 165, 165; hind foot, 406, 406; height at shoulders, 835, 762. 

 The ear from the notch, as well as can be determined from the 

 skins, varies from about 115 to 125. 



Skull measurements of 3 adult males: Total length, 266 

 (265, 266, 266); basal length, 254 (253, 254, 255); naso- 

 occipital length, 215 (211, 216, 218); front border of pre- 

 maxillae to front end of nasals, 64 (65, 65, 63); length of 

 nasals, 77.3 (73, 76, 83); zygomatic breadth, 112 (112, 112, 

 112); breadth of braincase at fronto-parietal suture (= post- 

 orbital constriction), 73 (74, 73, 72); mastoid breadth, 97 (95,
