BUSHBUCKS, KOODOOS, AND ELANDS 431 
adult male of the same race as haywoodi from a specimen 
taken at Nyeri, which is situated almost within the same 
watershed, but one hundred miles south of Sayer. Still 
more recently a specimen from Nakuru has been made the 
type of a new race, tjaderi , by Doctor J. A. Allen. 
The highland bushbuck is distinguishable by the dark 
seal-brown color of the old male, and the almost total ab¬ 
sence of white markings on the sides. The hind quarters 
usually show two or three spots, but occasionally they are 
absolutely wanting. The adult female is tawny rufous. 
The color of an old male is uniform raw umber-brown 
on the dorsal surface, but lighter on the rump, where there 
is some mixture with tawny hairs, and darker on the sides and 
breast, where the color becomes blackish seal-brown. The 
midline of the back is marked with a mane of long, white- 
tipped hair. On the sides are a faint indication of two 
transverse white stripes and two or three white spots on the 
flanks also. The tail is bushy; the dorsal surface and sides 
are rufous like the rump, the under-surface white, and the 
tip black. The legs are deep seal-brown like the belly, but 
are white on the inside of the axillae and at the groins. The 
inside of the forelegs from knees to pasterns and a similar 
stripe on hind legs from the hocks are tawny-ochraceous. 
The front of the pasterns is marked with a pair of large 
white spots. The neck is encircled by a well-marked collar of 
short hair at the base, which is bone-brown in color. The 
fore part of the neck is tawny with a short, black mane on 
the nape. There is a white bar at the base of the throat and 
a rectangular one on the forethroat. The crown and fore¬ 
head are bright-rufous, the snout umber-brown on top, and 
the sides of the face ochraceous-tawny. Below the eye on 
the cheek are two rounded white spots. The lips, chin, and 
upper throat are white. The ears are ochraceous-tawny on 
the back, with umber-brown tips and white inside. 
Immature males at an age when the horns are two or 
three inches long are like the adult females in color, but the 
collar at the base of the neck is darker and the indications 
of transverse stripes more pronounced. Males with horns 
half grown are less reddish than the females and quite uni¬ 
form wood-brown in color. The old adult female has the 
body bright russet on the midline of the back, and grades
