38 THE HORSE FAMILY. 



completely disappeared, and the principal stripes on the hind- 

 quarters are not narrower (and may be broader) than the 

 intervening spaces, which are white. In E. burchelli crawshayi 

 the stripes are relatively narrow and deep black in colour, while 

 the nostril-patches are yellowish brown, or tan, and the pasterns 

 are coloured like those of E. burchelli selousi. In E. burchelli 

 granti, on the other hand, the stripes are broader and apparently 

 less completely black, while the nostril-patches are black, and the 

 stripes on nearly the whole of the pasterns have fused into a 

 continuous black patch. 



The difference between E. burchelli granti and E. burchelli 

 typicus, in the matter of colour and pattern, is much greater than 

 that between the latter and E. quagga. 



Th 7 h The true Zebra [Equus zebra, M. 1024, fig. 25), often 

 termed the Mountam Zebra, ni order to distmguish it 

 from the Bonte-Quagga or BurchelFs Zebra of the plains, is a very 

 different animal to the last, and much more nearly related to the Ass. 

 In the first place, the direction of the hairs along the spine between 

 the withers and the rump is reversed, so that they are inclined 

 forwards instead of backwards. Secondly, the ears are longer, the 

 hoofs are narrower, and the tail-tuft is more scanty. Thirdly, all 

 the body-stripes, with the exception of two passing on to the rump 

 and hind-quarters, are continued upwards to meet the longitudinal 

 dorsal stripe which they cut at right angles ; while the area on 

 the rump between the dorsal stripe and the uppermost haunch-stripe 

 running to the root of the tail, in place of being longitudinally 

 striped, is marked by a series of transverse bars forming a 

 ^'gridiron-pattern."" The body-stripes stop short on the sides, so 

 as to be far removed from the ventral stripe. 



The Zebra was formerly found in all the mountain-ranges of 

 Cape Colony, but is now restricted to the Cradock district, where 

 it is protected by law. It was from this locality that the specimen 

 exhibited in the Lower Mammal Gallery was obtained. The 

 species is represented in Angola by Penrice's Zebra [E. zebra 

 penricei), and in Damaraland by Hartmann^s Zebra {E. z. hart- 

 mannce), which are, however, perhaps not separable from one 

 another.
