The Beisa Antelope, (Oryx beisa), is a good representative 
of the group of straight-horned antelopes found in the genus 
Oryx. Of all the long-horned species, the two Beisas and 
the Gemsbok of Africa, and the Beatrix of Arabia, are the 
only species possessed of horns that are practically straight

largest horns of record measure 40 inches. 
The Beisa inhabits eastern Central Africa, from Suakin 
on the Red Sea southward to the Equator.

Desert, is one of the rarest antelopes to be found in cap- 
tivity, and at this date this interesting species is represented 
by a fine pair of specimens. The longest horns of record 
measure 26 inches. Very few sportsmen have seen this

for three years, and has reared two young.

persons regarded as the handsomest of all the numerous 
species of African antelopes. In appearance it is very proud 
and high-headed; it has imposing horns that sweep backward 
in a semicircular curve; its large eyes and alert air betoken 
keen intelligence, and its glossy black coat, marked with pure
