196 THE HORSE AND ITS RELATIVES 



Burchell was described under the name of Equus 

 burchelli ; the English name of the animal then 

 becoming Burchell's zebra, a title which it is now 

 convenient to replace by the Boer name. 



As Central and Eastern Africa was gradually 

 opened up to European civilisation various other 

 animals akin to the bontequagga were discovered, 

 and in several instances received distinct names. 

 The range of these extended in one direction as 

 far north as Abyssinia, and in another as far west 

 as Damaraland. As we proceed north from Bechu- 

 analand, the home of the typical bontequagga, 

 it will be found that the representatives of that 

 animal gradually show the extension of dark stripes 

 on to the legs, till in the most northern forms 

 these are striped down to the hoof, and likewise 

 the disappearance of what are known as shadow- 

 stripes, that is to say, faint tawny streaks running 

 down the middle lines of the light stripes. In spite 

 of the great difference in these respects between 

 the extreme northern and southern forms, it is 

 quite evident that all of them are nothing more 

 than local races of the bontequagga. Indeed, they 

 have been regarded as nothing more than local 

 races of the quagga, from which, however, it is 

 convenient to separate all its relatives north of 

 the Orange River, in which the hind half of the 

 body is striped, as a distinct species. 



In regard to the presence or absence of striping
