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
