inches in cuninghamei and 21 inches in bohmi. The great- 

 est width of the obhque stripes on the hind quarters on granti 

 is 3 inches, while in cuninghafnei their width is only 2^ 

 inches, but in bohmi they are greatest of all, being 31^ inches. 

 The amount of actual color variation is slight but the color 

 pattern is extremely variable in certain parts, especially in 

 the region of the dorsal stripe and on the pasterns, that is, 

 the part of the leg immediately above the hoof. Usually the 

 dorsal stripe is bordered for its whole length by a white 

 stripe so that the lateral stripes do not unite with it. But 

 there is every intermediate condition from such an un- 

 broken dorsal stripe to one which unites with practically 

 all of the transverse and oblique stripes on the loins and 

 rump. The pastern region varies, independent of age or 

 sex, from a fully striped condition, in which the margin of 

 the hoof is marked by a broad whitish border, to a condi- 

 tion in which the lower half of the pastern is solid black 

 and the light band immediately above the hoof wholly 

 absent. There appears to be a fairly well-marked sexual 

 color difference in the nose, which in the males is black 

 only at the tip about the nostrils and the lips and bright 

 tan posteriorly between the nostrils and the tips of the 

 narrow forehead stripes. This area in the females is usually 

 black like the nostril area, the whole snout being black. 

 Shadow stripes occur on but a very small per cent of the 

 specimens. In a series of fourteen males from the Loita 

 Plains only two show shadow stripes, and in these they are 

 confined to faint traces on the hind quarters. One female 

 in a series of eight from the same locality shows shadow 

 stripes similar in distinctness and position. The shadow 

 stripes are individual affairs and are no more prevalent in 

 the young than in adults, as witnessed in a series of three 

 newly born young in which indications of shadow stripes 

 are present in only one of the specimens. The lesser width 

 of the stripes on the hind quarters, which is one of the 

 characters of the highland form, shows less variation than 

 the same dimension in the dorsal or the neck stripes. The 

 oblique stripes on the hind quarters vary in different indi- 

 viduals in greatest width from 2}^ to 3>? inches, the dorsal 

 stripe from 2)4 to 5>^ inches, and the broadest neck stripe 

 from 2^ to 4 inches. One of the distinctive features of this
