of the most beautiful of the oryx group lies in the fact that some of these animals 
still linger in imaccessible parts of Portuguese and German South-West Africa. At one 
time they were fairly numerous about fifty miles to the south of Mossamedes, where 
the present writer saw them (and also on the Upper Kunene River) in 1882. 
In Eastern Africa (Somaliland north of the Tana River), and in the Egyptian 
Sudan east of the Nile and west of the Red Sea, the Beisa oryx is found. This 
form is obviously a more primitive type than the gemsbok. The long, straight horns 
however, grow closer together at the tips, and the body markings are not nearly so

bold in their abrupt contrast of black and white. In the photograph on page 171 of the 
Beisa, it will be seen that the horns have a slight convex curve, more lke those of the 
Leucoryx. The fact is that there is more variation in the shape of the oryx horns 
than is generally thought, and a constant tendency for them to revert to a more curved 
condition. In Eastern Africa south of the Tana river and between Lakes Taganyika, 
Victoria, and the Indian Ocean is found another form of beisa which is remarkable 
for its long and black-tufted ears which recall those of the roan antelopes.
