QUAGGA. 33 



'Small as in the Horse ; and, as in that species, the mane extends on 

 to the withers, and the tail-tuft is large and full. Furthermore, the 

 large, broad, and thickly-haired ears are quite different from those of 

 all other members of the family, which are narrow and pointed. The 

 large size of the ears and the narrowness of the stripes appear to be 

 adaptations to a life partially spent in thick scrub, as is shown in 

 a photograph by Lord Delamere, exhibited in the lower mammal 

 -gallery. A fine male specimen of the species, presented by 

 Gen. Sir A. H. Fitzroy Paget, is shown in the large Zebra case 

 in the same gallery. 



The colour-pattern of Grevy^s Zebra may be described as 

 follows : — The dark (dark brown or black) and light stripes on the 

 body, head, and limbs are for the most part very narrow, widening 

 out only on the lower jaw, on the neck, and on the lower part of 

 the thigh. On the flank none of the stripes bend backwards and 

 upwards to extend on to the hind-quarters, the upper portion of 

 which is marked with vertical stripes arranged concentrically round 

 the root of the tail. The dorsal stripe is very broad, especially 

 near the middle of the back ; and there are no transverse stripes on 

 the under-parts. The stripes on the nose practically stop short 

 of the nostril-patches, and the nose itself is greyish. 



It will be evident from this description that in the present 

 species the stripes on the rump have their concavity directed 

 upwards, whereas in the next species the convexity is upwards. 



Two races, or subspecies, of Grevy^s Zebra have been named. 



J, j» The extinct South African Quagga {Equus quagga, 



^ ^^ " M. 1 01 7, fig. 22), together with the following striped 

 species, has the callosities on the front legs larger than in Grevy's 

 Zebra, and the stripes broader. In this group, whenever the hind- 

 quarters are striped, the stripes are obliquely longitudinal, with 

 the uppermost ones arising from the posterior region of the body, 

 where their upper extremities are bent backwards towards the root 

 of the tail in such a manner that there is no concentric arrangement 

 round the latter. The muzzle is dark, and usually black, and the 

 stripes on the nose are continuous with the dark patches round the 

 nostrils. The ears are narrow. 



In the Quagga, which was confined to the plains south of the 

 Orange River, the ears are comparatively small, the front hoofs are
