THE GRYS-BOK AND OUREBI. 645 
The Grys-Box, two females of which animal are represented in the accompanying 
illustration, is a native of Southern Africa, and is about the same size as the preceding 
animal, its height at the shoulder being between nineteen and twenty inches. 
It is not very often found on the plains, but prefers to inhabit the wooded portions 
of the mountainous districts, and is an especially wary and vigilant creature, and endowed 
with great powers of speed. The colour of the Grys-bok is ruddy chestnut, largely 
intermixed with white hairs, which give it a stippled appearance, and have caused the 
Dutch Boers to term it the Grys-bok, or Grey-buck. The under portions of the body are 
GRYS-BOK.—Calotragus melandtis, 
not white, as is so often the case among the Antelopes, but are of a reddish-fawn. The 
ears are more than four inches in length, and from their conspicuously black tips have 
earned for the Grys-bok the scientific title of Melanotis, or black-eared. The hoofs are 
peculiarly small, sharp, and black, and the tail is so short that it barely protrudes beyond 
the hair of the hinder quarters. 
The OUREBI is another of the many Antelopes which inhabit Southern Africa. For 
the following graphic description of its appearance and habits I am indebted: to the 
kindness of Captain Drayson. 
“Whilst many animals of the Antelope kind fly from the presence of man, and do not 
approach within a distance of many hundred miles of his residence, there are some few 
which do not appear to have this great dread of him, but which adhere to particular 
localities as long as their position is tenable, or until they fall victims to their temerity. 
It also appears as if some spots were so inviting, that immediately they become vacant by 
the death of one occupant, another individual of the same species will come from some 
unknown locality, and re-occupy the ground. Thus it is with the Ourebi, which will stop 
in the immediate vicinity of villages, and on hills and in valleys, where it is daily making 
hair-breadth escapes from its persevering enemy—man. 
When day after day a sportsman has scoured the country, and apparently slain every 
Ourebi within a radius of ten miles, he has but to wait for a few days, and upon again 
any P
