THE GREVY ZEBRA

seal-brown to bistre, and are always a decided brown rather 
than black in tone. They are darkest on the neck and 
lightest on the rump and face, where they sometimes as¬ 
sume a reddish tint or chestnut color. The median ventral 
stripe is hair-brown and much lighter than the stripes on 
the dorsal surface. The nose is marked by a bright-tawny 
patch bordered behind by an unstriped area of pale-buff 
and in front by the white lips and chin. The terminal half 
of the ears is seal or bistre brown, in contrast to the pale- 
cream ground-color of the lower half and inner side. The 
tail tuft is rather shorter than in other zebras and measures 
only 9 or io inches in length. In appearance it is cream- 
white above, lined below by black hair. From the crown 
to the withers extends a short, erect mane some 6 or 7 inches 
in height and striped alternately with light and dark trans¬ 
verse stripes continuous with their fellows on the neck. 
No variation in mane due to age, such as takes place in the 
quagga, occurs in this species. The newly born young are 
quite reddish on the body, due to the russet color of the 
body stripes, but the forward half of the body and the legs 
are striped by dark seal-brown, as in the adults. At this 
early age the nape mane is short and fuzzy and continuous 
along the midline of the back by a low mane covering the 
dorsal stripe. The striped pattern in the adult consists of 
twenty or twenty-two transverse dark stripes on the body 
between the shoulder stripe and the hip stripe, the stripes 
having a width of 1 to 1^ inches, the light interspaces 
being somewhat narrower and measuring ^ of an inch in 
width. They extend vertically from the light border of 
the dorsal stripe to the lower sides, but do not cross the 
belly and join the ventral stripe, but terminate abruptly 
on the lower sides. Posterior to the hip stripe the rump is 
marked by very narrow transverse stripes ^2 inch in width, 
which are somewhat diagonal in direction and become 
progressively shortened as the base of the tail is approached. 
Below the forking of the hip stripe the transverse leg stripes 
begin and continue down the hind limb to the hoof. The 
middle line of the back is marked by a broad dorsal stripe 
2 inches wide from the withers quite to the tail tuft and is 
bordered for most of its length by a broad light stripe of the 
ground-color, except on the withers, where the transverse
