the Cape Colony i^uaggas. 323 



The breast, belly, legs, and tail are white, with the 

 exception of the brown median ventral band ; some black 

 hairs on the back of the pastern and fetlocks and on the rim 

 of the hoof. The tail is said to be furnished with elongated 

 hairs from the root; but, judging from the photograph, the 

 basal third is covered with short hairs. 



This animal differs from E. qungga Oreyi as exemplified 

 by the specimens represented in York's photograph, and by 

 those in the British and Amsterdam Museums, by the extreme 

 narrowness of the interspaces between the stripes upon the 

 head, neck, and shoulder, and by the sharpness of their 

 definition upon the body, which enables the striping to be 

 traced with certainty even back upon the hind-quarters. The 

 regularity of the banding of the neck is also very noticeable. 



From E. quagga quagga it differs by having the inter- 

 spaces narrow and cream-coloured, the stripes very broad and 

 brown, and by the presence of stripes upon the posterior half 

 of the body and on the hind-quarters. 



I have given the description of this quagga somewhat 

 fully because, in my opinion, it is the one of all others wliich 

 proves by the arrangement of the stripes upon the posterior 

 half of the body and hind-quarters that these animals are 

 nothing but extreme forms of BurchelFs Quagga, differing 

 from the typical race of that animal not more — in some 

 cases, indeed, in my opinion, less — than the latter differs from 

 its more northern relatives, and thus justifying the view I 

 have already published that, as species are at present reckoned 

 in the equine group, the various races of Burchell must be 

 regarded as subspecies of E. quagga *.

 This form seems to differ from Lorenzi in the folio wins* 



* Vernacular names in zoology are of no great moment, except in so 

 far as they are apt to fog the mind of the layman on the question of 

 relationships. Tell him that E. Grevyi, E. zebra, and E. Burchelli are 

 zebras, and that E. Lorenzi is a quagga, and he very naturally infers that 

 the first three are clo.*ely related and the last a quite distinct form. To 

 obviate this error in part I have proposed to extend the term " Quagga " 

 to all the Burchelline Equidse, and thus to bring the technical "and 

 vernacular terminology into accord ; and I think that until it can be 

 shown that there is a greater gulf between Loreuz's Quagga and Bur- 

 chell's Quagga than there is between Burchell's and Grant's Quaggas, it is 

 misleading to bracket the latter two as " Boute Quaggas '' and to restrict 

 the term " Quagga " to the forms coustitutiiig the subject-matter of the 

 present paper.
