COMMON ZEBRA OR BONTE-QUAGGA 697 



dication of shadow stripes anywhere. The widest stripes 

 are the obHque ones crossing the hind quarters, which have 

 a width of 2^4 inches at their widest part. The body is 

 crossed behind the shoulders from the last neck stripe to 

 the first oblique stripe by four transverse stripes, which 

 completely encircle the body and join the longitudinal ven- 

 tral stripe. The neck is crossed by nine transverse stripes, 

 the anterior of which are narrow and a few of the posterior 

 very wide. The leg stripes are broken on the inner side on 

 the upper part of the legs, but below the knees and the 

 hocks they completely encircle the legs, and on the lower 

 part of the pasterns, immediately above the hoof, they 

 usually become fused into a solid dark band. 



There is in addition to the type skin at the National 

 Museum another skin of the same age taken at the same 

 time. This latter specimen is quite identical in color with 

 the type. Specimens of granti of the same age from the 

 Athi Plains differ from the type by their whitish ground- 

 color and dark stripes which are seal-brown in color. The 

 stripes of the old adults of cuninghamei, however, as observed 

 in the live specimens in the field, are somewhat darker than 

 the type but are never deep black as in granti. The lighter 

 color of the dark stripes is no doubt due to the arid condi- 

 tions and intense heat and sunlight to which the Northern 

 Guaso Nyiro race is subject. Ciininghamei is a desert race 

 occupying the Northern Guaso Nyiro watershed from its 

 formation by the Guaso Narok and Guaso Nyuki Rivers 

 eastward to its termination in the Lorian swamp. North- 

 ward the race reaches at least as far as the northern slopes 

 of the Lorogi Mountains. The quagga zebras occurring 

 along the east shore of Lake Rudolf may be jollcz, the 

 Abyssinian race, which was described by Camerano from 

 the Rift Valley of central Abyssinia. 



A fully adult male from Archer's Post, Northern Guaso 

 Nyiro River, had the following flesh measurements: head 

 and body, 75 inches; tail, 18 inches; hind foot, 20 inches; 

 ear, 6^^ inches. These flesh measurement are considerably 

 less than adult males of the highland quagga.
