AFRICAN GAME ANIMALS 
The highland quagga of British East Africa was described 
as a distinct race in 1896 by DeWinton, from specimens col¬ 
lected near the Thika River by Doctor J. W. Gregory, who 
has given us an account of his journey in “The Great Rift 
Valley.” In the original description, which is very brief, 
DeWinton makes no allusion to his use of Grant’s name for 
this race. He has named the race, without doubt, for Colonel 
Grant of the Speke and Grant expedition, who mentions 
the zebra in his notes in the natural history account of the 
expedition, published in 1872, where he calls attention to 
the color differences between this race and the typical 
Burchell zebra of South Africa. Sportsmen, however, 
seem to be very uncertain as to the distinctness of this 
race from those found south of the Zambesi River and often 
refer to the East African race as “Chapman’s.” They have, 
no doubt, been led to this course by the occasional presence 
of faint shadow stripes in specimens which in this respect 
resemble the Chapman zebra. Although shadow stripes 
are occasionally present on the hind quarters in specimens 
from British East Africa, the absence of such stripes is much 
more common and must be accepted as one of the char¬ 
acters of the highland race known to naturalists as Equus 
quagga granti. Other characters for the race in compari¬ 
son with South African forms are the great width of the 
dark stripes on the hind quarters, the whiteness of the light 
stripes, and the fully striped character of the legs. The 
stripes are especially numerous on the pasterns above the 
hoofs, where they unite to form a wide black band covering 
nearly the whole pastern region. The quagga zebra, com¬ 
monly known as the Burchell zebra, covers a great expanse 
of territory in East Africa, as well as a great altitudinal 
range, and is consequently subject to great diversity of 
climatic conditions. Nevertheless, they show almost no 
color changes which agree with difference in environment. 
This is in marked contrast to their color behavior in South 
Africa as well as to the color behavior of the Grant gazelle, 
giraffe, and a host of other species with which they are in¬ 
timately associated in East Africa and which exhibit well- 
marked geographical differences in color over the same 
area. The zebra affords us a striking example of how 
independently species react to environment and how ob-
