DUIKERS AND SMALL ANTELOPES 575 



but rrtay be distinguished by its lighter-colored legs, brighter 

 golden body color, more pronounced or extensive black 

 bands above the hoofs, and dark-rufous forehead and 

 crown. 



The dorsal color is bright buff-yellow, and is everywhere 

 speckled by seal-brown, owing to the basal color of the hair 

 showing beneath the narrow yellow tips. The yellow is 

 purest on the neck. The midline of the back shows most 

 blackish, and is uniform in color with the rump. The sides 

 are sharply defined against the pure white of the under- 

 parts. The tail is not differentiated by color or longer hair 

 from the rump. The forelegs are lighter-colored than the 

 back, being buffy, with less of the dark hair bases showing 

 through on the outside, and the inside is uniform whitish, 

 like the under-parts. A heavy black band encircles the 

 hoofs and reaches half-way to the false hoofs. The hind 

 legs are like the fore, but the inside from the hocks to the 

 hoof is uniform in color with the outside. The crown of 

 the head is russet, lined heavily by black. The snout is 

 buffy on the sides, like the legs, but the median portion is 

 blackish. The lips and chin are whitish. The midline of 

 the throat is buff-yellow, without darker vermiculations. 

 The backs of the ears are clothed by short, buffy hairs, but 

 the central portion and margin are blackish, except on the 

 lower inner border, which is marked by a white bar or spot. 

 The inside and the base of the ear are whitish. 



The Marsabit race is practically identical in size with the 

 Masailand form. An average specimen gives the following 

 measurements in the flesh: head and body, 33 inches; tail, 

 ^yi inches; hind foot, 9 inches; ear, 3^ inches. Greatest 

 length of skull, 5^2 inches. A single male is in the collec- 

 tion. The horns of this specimen measure 3^ inches. 



Specimens of this race were secured on the summit of 

 Mount Lololokwi, at six thousand feet altitude, and on the 

 rocky kopjes which dot the west Kenia plateau. They were 

 also seen on the slopes of Mount Uaragess, but nowhere 

 were they encountered in the low desert region, and it is 

 doubtful if they occur below an altitude of three thousand 

 feet.
