44 WILD BEASTS OF THE WORLD 



with the legs and some patches on the muzzle and cheeks very dark 

 brown, and the tip of the tail black. Several specimens have been 

 exhibited in the London Zoological Gardens. 



THE LEUCORYX 



(Oryx leucoryx) 



THE Leucoryx, which is rather smaller than the Beisa Oryx, is the 

 most distinct of all the Oryxes, owing to its horns having a strong 

 backward crescentic curve, instead of being straight as in the rest ; 

 they may exceed a yard in length. The general hue of the animal 

 is cream-colour, darkening into brown on the neck and shoulders ; 

 the face-markings nose-patch and eye-stripes are brown instead of 

 black. This species is found from Dongola to Senegal, inhabiting 

 deserts in herds ; it gets much of its food by browsing on acacia 

 twigs, and the Arabs hunt it on horseback for its flesh, which they 

 esteem highly, and its hide. It is not a very common animal in 

 collections, but has lived and bred in the London Zoological Gardens. 



THE ADDAX 



(Addax naso-maculatus) 



THE Addax is closely allied to the Oryxes, and similar in general 

 form, but its horns are very different, having a decided spiral twist 

 much like those of the Koodoo, though they are ringed like those of 

 the Oryxes. In the female they are much thinner than in the male, 

 and have the spiral twist less pronounced. A male's horns may 

 measure a yard along the curve. The Addax is rather less than a 

 yard in height at the shoulder; in colour it is a light brown, greyer 

 in winter and redder in summer, with the haunches and all the limbs 

 white, a black patch of long hair on the forehead just below the 

 horns, and below this two white patches, meeting each other across 

 the nose. The Addax has the same range as the Leucoryx, and is 

 also a scarce animal in collections, though our Zoological Society has 

 exhibited it.
