My illustration (text-fig. 142, p. 549), by the kind permission of 

 Messrs. Rowland Ward & Co. and of Mr. R. Lydekker, F.R.S., is 

 from the latter's ' The Game Animals of Africa,' fig. 23, p. 65. 



In the Burchelline group the enlargement of the stripes seen 

 on the haunches of the Mountain Zebra is found all over the body. 

 The stripes are far larger and fewer in number, whilst in many 

 varieties shadow stripes are seen, the vestiges of the closer 

 striping still surviving in the Grevy and Mountain species.

H. burcJielU (var. granti). 



The most northerly variety of this species is Grant's Zebra 

 (text-fig. 143) found all over East Equatorial Africa. As we 

 advance southwai-ds we find it shading ofl^ into Chapman's variety 

 found in the Transvaal, in which the legs are no longer striped 

 down to the hoof (text-fig. 144), whilst in the typical Burchell 

 Zebra or Bonte Quagga of the Orange River Colony the legs and 

 the under surface of the body are free from stripes (text- 

 fig. 145, p. 552).
