AFRICAN GAME ANIMALS 
on the sides gradually into bright-tawny. The legs are 
marked as in the male, but the upper part is much lighter- 
tawny instead of seal-brown. The head is colored quite as in 
the male; the neck, however, is lighter tawny like the body. 
The median dorsal line lacks the mane found in the male, 
which is indicated only by a dark stripe with occasional 
streaks of white hair. There is no indication on the sides of 
spots or transverse bands. Younger females show a row of 
white spots on the sides and indications of one or two trans¬ 
verse white stripes. Newly born young are like the young 
females in color and pattern, but lack the dark leg stripes, 
and have the head colored as in the adult. The collar is in¬ 
dicated by the dark-brown color of the hair on the nape, 
which is no shorter than on the rest of the neck. It is sur¬ 
prising how slight the color differences are between the 
nursing young and the adult female in a group showing such 
great sexual color difference in the adults. The absence of 
any indication in the young of the remote ancestral color¬ 
ation would indicate great age in the present color pattern. 
The type specimen collected at Sayer by Lord Delamere 
is an immature female with the milk teeth and first molar 
only in use, and has every appearance, as far as the skull is 
concerned, of being a kid six months old. The skin is in a 
faded condition and apparently lacks the white areas on the 
inside of the legs. It is matched closely in color by some 
skins of adult females from the Aberdare Mountains which 
show the same wood-brown color and absence of all spots on 
the sides and hind quarters. The collar of short hair on the 
neck is not always well marked in adults and is occasionally 
lacking, as is the case in the type of haywoodi which was one 
of the distinguishing characters used by Thomas for the 
race. The amount of white spotting on the sides is quite 
variable and is sometimes absent, as in the type specimens 
of both delamerei and tjaderi. The white chevrons on the 
snout are also subject to great individual variation in con¬ 
stancy, and their presence is of no racial value as a char¬ 
acter. A large number of specimens have been examined 
from the Aberdare Mountains, Lake Naivasha, the Loita 
Plains, and the Uasin Gishu Plateau. This race is very sim¬ 
ilar in color to sylvaticus of the Zambesi region, the differ¬ 
ence being much less than in the Uganda bushbuck, with
