being also barred. The outsides of the ears have a Avhite tip and 

 a broad black mark occupying the greater part of the surface, but 

 are white at the base. Perhaps the most constant and obvious 

 distinction between this species and the next is the arrangement 

 of the stripes on the hinder part of the back, where there are a 

 number of short transverse bands passing from the median longi- 

 tudinal dorsal stripe towards, and sometimes joining with, the 

 uppermost of the broad stripes which run obliquely across the 

 haunch from the flanks towards the root of the tail. There is often 

 a median longitudinal stripe under the chest. 



Fio. 162. Burchell's Zebra (Equus burchelli). 



E. burchelli (Fig. 162) is a rather larger and more robust animal, 

 with smaller ears, a longer mane, and fuller tail. The general 

 ground colour of the body is pale yellowish-brown, the limbs nearly 

 white, the stripes dark brown or black. In the typical form they 

 do not extend on to the limbs or the tail ; but there is a great 

 variation in this respect, even in animals of the same herd, some 

 being striped quite down to the hoofs (this form has been named 

 E. chapmani). There is a strongly marked median longitudinal 

 ventral black stripe, to which the lower ends of the transverse side 

 stripes are usually united, but the dorsal stripe (also strongly 

 marked) is completely isolated in its posterior half, and the upper- 

 most of the broad haunch stripes runs nearly parallel to it. A 

 much larger proportion of the ears is white than in the other 

 species. In the middle of the wide intervals between the broad
