THE GREVY ZEBRA

quagga is equally abundant in their domain and shares much 
of the same territory as the former. It is commonly as¬ 
sumed that the Grevy zebra occurs on the plains of Shoa, in 
the vicinity of Addis Abbaba, the capital of Abyssinia, but 
this is by no means the case. The Grevy zebra is confined 
to the Rift Valley of Abyssinia, from Lake Zwai south¬ 
ward, and is an inhabitant of low desert or semiarid 
country, very different in character from the cool, moist 
Abyssinian highlands of the capital. It is doubtless from 
the northern extremity of the range, in the vicinity of 
Lake Zwai, that the specimens donated by Menelik to 
foreign rulers have come. At the present time the Grevy 
zebra is not found as far north as that district, but its 
absence there may be due to recent extermination by the 
Abyssinians consequent upon the extensive introduction 
of firearms in the country. Specimens from the western 
frontier of Somaliland have been separated by Pocock as 
a race, owing to the dark stripes being seal-brown rather 
than black. Such color differences, however, are due merely 
to the fading effect of the intense desert light and heat. 
The specimens with which the Somaliland ones were com¬ 
pared were zoological-garden specimens, obtained by dona¬ 
tions originally from Emperor Menelik. The pure white 
character of their light stripes and the blackness of the 
dark stripes is due chiefly to the temperate climate in 
which they were living. There is practically no difference 
in environment and very little in geographical position to 
warrant a race in southeastern Abyssinia. In this connec¬ 
tion it may be stated that specimens from British East 
Africa are quite identical in shade of coloration of both the 
dark and the light stripes to those from Somaliland. Mat- 
schie, some years previous to Pocock’s description of berber- 
ensis , gave the name faurei to a specimen living at the 
Zoological Gardens of Paris which had been sent by Menelik 
as a gift to President Faure of France. The name was 
based on a photograph of the specimen which gave it the 
appearance of having a white tail tuft, the character by 
which Matschie distinguished his race. The specimen in 
question, however, has the tail tuft normal in color, that is, 
white on the upper side or outside as it hangs down and 
black on the inner or lower side. The black inner side of
