Fig. 0. THE ACCLIMATIZATION OF THE GRANT ZEBRA. Equus granti. 



Man-, and foal born July 17. 1911. The mare shows the black muzzle, diamond-shaped pattern of the star on the forehead, black, 

 erect mane, which extends back into the thin dorsal stripe and broad gridiron over the hips. The slender limbs of the zebra colt 

 have nearly the same length as the limbs of the mother, although the body is very much shorter. This enables the colt to keep pace 

 with its mother in escaping the attacks of the lion, the chief enemy of the Grant zebra. 



stripes of the Grant zebra, which, as shown in 

 Figs. 9 and 10, so completely surround the body 

 that they unite with a black line extending 

 along the under surface of the belly. Grant'.; 

 zebra, like the Grevy. has a very conspicuous 

 set of horizontal stripes extending down the 

 legs to the hoofs, and is thus readily distin- 

 guished from the Chapman zebra in which the 

 lower portion of the leg is quite pale. 



The Grant is typical of a very large group 

 entirely distinct from the Grew and Mountain 

 zebras. It is broadly known as the Burchell 

 group, the type of which was the zebra found 

 and described by the English explorer Burchell 

 north of the Orange River, which roamed north 

 of that stream as the Quagga roamed to the 

 south. In the typical Burchell zebra (E. bur- 

 rhelli, now believed to be quite extinct) the 

 entire legs are devoid of stripes, so that the 

 zebras of the Burchell group from the Grant 

 zebra on the extreme north of British East 

 Africa to the extinct Quagga of the Cape of 

 Good Hope region, once presented a complete 

 color transition from the universal striping in

Showing the broad striping, and the thoroughness with 



which the striping of the legs is carried down 



to the hoofs.
