36 THE HORSE FAMILY. 



venient names as " Chapirian^s BurchelFs Zebra. '^ The species is 

 very closely allied to the Quagga, from which perhaps it is not 

 really separable ; but the stripes are always well developed on the 

 hind-quarters, where they present the characters mentioned under 

 the heading of that animal. The species displays remarkable 

 variation in colouring and markings as we proceed from south to 

 north ; the typical southern race (fig. 23) having dark brown 

 stripes with intervening brown '^ shadow-stripes '^ on an orange 

 ground, and un striped legs, whereas in the northern race (fig. 24) 

 the stripes, which are black on a white ground, extend down to 

 the hoofs, and have no intervening shadow-stripes. 



In all cases the upper extremities of some five or six stripes on 

 the hind half of the body are bent backwards parallel to the dorsal 

 stripe ; while the light area between these body-stripes and the 

 dorsal stripe is continued to the root of the tail, and is not crossed 

 by transverse bars, but traversed longitudinally by the backward 

 extension of at least one of the body-stripes. 



The typical Burchell's Bonte-Quagga, or BurchelPs Zebra (Equus 

 burchelli typicus, M. 1018^ fig. 23), now nearly, if not completely, 

 extinct as a wild animal, formerly inhabited British Bechuanaland 

 and some of the adjacent districts in enormous droves. In this race 

 the ground-colour is orange, and the shadow- stripes on the hind- 

 quarters are very strongly marked, and narrower than the main 

 stripes, which are themselves broader than the light interspaces 

 containing the shadow-stripes. The hind -quarters have only a 

 few short stripes below the long stripe running to the root of the 

 tail ; the body-stripes stop short on the sides of the uuder-parts, 

 so as to be widely separated from the longitudinal ventral stripe ; 

 and, with the occasional exception of a few on the knees and hocks, 

 the legs are devoid of stripes, as are usually the sides of the tail. 



This race is represented by a specimen from the Orange River 

 Colony, the gift of the Hon. Walter Rothschild. 



The next race (and only some of the more important ones are 

 here referred to) is the Damaraland Bonte-Quagga [E. burchelli 

 antiquorum) in which stripes are developed above the knees and 

 hocks, but none (or very few) below^ It is unrepresented in the 

 exhibited series.
