Oryx beatrix. 



Oryx beatrix, Gray P.Z. S., p. 158, pi. Iv (1857) ; P. L. Sclater P. Z. S., 

 1872, p. 603 ; id. P. Z. S., 1878, p. 789. 



Distribution. — Arabia, one specimen was got from near INIecca, 

 the other from Bushire. 



A skull identified by BIyth as O. leucoryx seems to be rather 

 referable to O. beatrix than to O. beisa ; the horns are quite 

 straight, so that it is certainly not O. leucoryx.
