bony knobs on the frontal bones of the skulls. The color 
differences of this race are very slight indeed, and it is dis¬ 
tinguishable with difficulty by coloration from the race oc¬ 
curring south of it, ciceros, in southern German East Africa, 
south to the Zambesi. It is difficult to account for the pres¬ 
ence of horns in the females of a race having no peculiar 
habits, and surrounded on all sides by races in which the 
females are not only hornless, but show no tendency to¬ 
ward the acquiring of such structures. 
Average male specimens measure in the flesh 33 inches 
in length of head and body; tail, 3^ inches; hind foot, n 
inches; ear, 3F2 inches. Females are fully equal in size to 
the males. The longest-horned specimen is a female in 
which the horns are 4^ inches in length. The longest male 
horns are 3^ inches. These horn dimensions are exceeded 
very little by Ward’s record for East Africa of 4^ inches.” 
The skull length of the two sexes is quite equal, the longest 
female skull being 5^ inches, and the longest male 5^ 
inches. 
The distribution of the klipspringer is quite local, owing 
to their occurrence only on barren, rocky hills or mountain¬ 
sides. The Rift Valley, with its innumerable lava cliffs and 
rough broken surface, is a favorite haunt of this race. 
They are distributed throughout the valley from central 
German East Africa and Kilimanjaro north to Lake Ba- 
ringo. Upon the slopes of the volcanic cone of Longonot, 
immediately south of Lake Naivasha, they are particularly 
common and occur from its base to the summit, at nine 
thousand feet, where they reach their highest altitudinal 
range.
