the Cape Colony Qaaggas. 323 



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

 exct'|)tion of the brown median ventral band ; some black 

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

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

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

 basal third is covered with short hairs. 



This animal differs from E. qungqa Greyi as exemplified 

 by the specimens represented in York's [diotograph, 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. Tiie 

 regulaiity 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 which 

 ])roves by the airangenunt of the stripes upon the posterior 

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

 nothing but extreme forms of BurchelTs 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 tlius 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 following 



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

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

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

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

 the first tliree are clo.-'ely related and the last a quite dLstinc't form. To 

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

 to all the Burcht'Uine Iviuidoe, and thus to bring the technicaf "^uid 

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

 shown that there is a greater gulf betsveen Loreuz's Quagga and Rur- 

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

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

 the term " Quagga'' to the forms constituting the subject-matter of the 

 present paper.
