peared to be only a small variety of O. gazella, the smaller size de- 

 pending on some peculiarity in the climate or locality, as is the case 

 with the Strepsiceros /melu found in Abyssinia by Capt. Harris, 

 which is only half the size of that inhabiting the Cape of Good Hope. 

 The O. leucoryx, on the other hand, which is confined to Senaar 

 and Senegal, is vvithout any indication of the lateral streak. 



The animal uow under consideration is intermediate between these 

 species ; it has the straight horn of A. gazella and the plain colour 

 of A. lencoryx, but its dark legs and pecuhar white feet at once 

 separate it from either. 



The animal was presented to the Society by Capt. John Shepherd 

 of the India House ; it was regarded in the Gardens as a half-grown 

 Oryx gazella, and is said to have been brought frora Bombay. A 

 pair was shipped from the latter port, but the feiuale died at sea. 

 The malė is now in the CoUection of the British Museum. 



Oryx Beatrix. The Beatriče. (PI. LV.) 



The horns slender, straight, or only very slightly curved near the 

 tip, annulated nearly to the tip. White ; a spot on the niiddle of 

 the face, a smaller spot between the base of the horns, a large 

 patch on each cheek, extended above up to the eyes, and united to- 

 gether beneath under the throat ; the knees and front of the fore- 

 and hind-legs, and a large spot on the chest, dark blackish brown ; 

 the legs to the posterior grey-browu ; end of the tail black. 



Hcib. Bombay, but probably brought from the shores of the Red 

 Sea. Brit. Mus. 



This specimen is not half the size of the Gemsboc from the 

 Cape, and is immediately known from it by the distribution of its 

 colour s. 



In form and size it resembles the true Orj'^x (O. leucoryx), but it 

 differs in the straightness of the horn, the size and form of the cheek- 

 spot, and especially in the dark colour of the legs, and the well- 

 marked white ring around the fetlock joint just above the hoof. 



The hair is whorled on the middle of the haunches likę the ręst of 

 the genus, and the hairs of the back in front of the withers are 

 directed forwards.
