stripes unite with it. The neck is marked by nine or ten 
transverse stripes varying much in width, the widest being 
the median ones, which attain a width of 2^ or 3 inches. The 
crown of the head is marked by numerous very fine longi¬ 
tudinal stripes which terminate on the snout midway be¬ 
tween the tip and the eyes. The sides of the head and the 
cheeks are marked by wider transverse stripes which meet 
below on the throat. The legs are marked by numerous 
narrow transverse stripes which completely encircle the 
limb with the exception of the upper part, near the body, 
where they are broken on the inner side. A series of twelve 
adult skins from the Northern Guaso Nyiro district show 
very little variation in color. The stripes, however, vary 
considerably in different individuals or on different sides of 
the same individual. The transverse stripes of the back and 
neck often fork irregularly on the sides of the body, and the 
leg-bands are even more irregular in this regard. Albinism, 
though rare, is not unknown among Grevy zebras, but no 
instances of partial albinism have been reported. One of 
the British East African game rangers, A. Blayney Percival, 
collected a uniformly white specimen near the Lorian 
swamp from a herd of normally colored individuals. This 
specimen was presented by Percival to the British Museum 
and is now on exhibition in one of the galleries. Although 
it is entirely white, the dark stripes can be traced in its coat 
as faint darker shadows. 
An adult male specimen from the Northern Guaso Nyiro, 
shot by Colonel Roosevelt, measured in the flesh: head and 
body, 8 feet 3 inches; tail, 22 inches; hind foot, 24 inches; 
length of ear, 9 inches. These dimensions represent an 
average adult of either sex, the females being quite equal 
to the males in size. The largest skulls in a series of four¬ 
teen specimens in the National Museum measure in greatest 
length: male, 25 inches; female, 24^ inches. Specimens 
have been recorded by A. H. Neumann in British East 
Africa as far south as the junction of the Tana and Mac¬ 
kenzie Rivers, east of Mount Kenia, thence northward to 
the northeast slope of the Lorogi Mountains and northward 
along the east shore of Lake Rudolf to the mouth of the 
Omo River. No authentic records of Grevy zebra in the 
Turkana country west or southwest of Lake Rudolf have
