46 Mr. R. I. Pocock on the 
hind leg there are stripes on the inner side of the cannon- 
bone; but for the rest the inner surfaces of the legs are 
unstriped, though the ends of the stripes of the outer side 
extend round the front and back of the limbs. The nostril- 
patches are coffee-brown. 
This form seems to be an exaggeration of the type known 
as Chapmannt, but appears to be separable from it by strength 
of the leg-markings and the much blacker fetlocks and 
pasterns. From Wahlberg? it is strikingly different, not only 
in the striping of the legs but also in that of the body and 
quarters, the principal stripes being noticeably wider as 
compared with the pale interspaces and the shadow-stripes 
very much fainter. 
A second specimen of this subspecies that I have seen was 
also obtained in Mashunaland by Mr. Selous, and forms part 
of the collection of the Hon. Walter Rothschild at Tring. It 
substantially agrees with the type, but has the shadow-stripes 
more conspicuous on the flanks. 
Subspecies Crawshay?, de Winton. 
Equus Burcheili Crawshaii, de Winton, Ann, & Mag. Nat. Hist. (6) 
xvii. p. 319 (1896). 
Of this subspecies, which inhabits the highlands of British 
Central Africa to the west and south of Lake Nyasa, the 
British Museum possesses three skins—one (the type) from 
Henga (Crawshay), a second from British Central Africa 
(A. Sharpe), and the third (a foal) from Mount Zomba, also 
obtained by the last-named collector. 
In general appearance Crawshayi most nearly approaches 
the Mashunaland form Selousi?, but is quite distinct from the 
latter, as from all the other subspecies of Burchelli, as 
Crawshay (Proc. Zool. Soc. 1895, p. 689) originally sup- 
posed. In the first place, there is no trace of shadow-stripes 
even on the quarters, where the stripes, black, as in other 
parts of the body, are as broad or even broader than the 
intervening spaces. ‘The tail is not decidedly striped laterally, 
but strongly spotted, with the tuft black. The legs are, if 
anything, even more strongly striped than in Selows??, the 
pasterns being black above the hoof and the inner surface 
barred from the knees and hocks downwards. And, lastly, 
the nostril-patches are bright tan in colour. It may be 
added, moreover, that there is a strong tendency in this form 
for the upper quarter stripes to break up into a network of 
bars which presents a superficial resemblance to the so-called 
eridiron pattern of the mountain zebra. Similar variations, 
however, are not infrequent in zebras of the Chapmanni type.
