gazella), the horns are straight ; in the true Oryx (0. leucoryx), they 

 are arched and recurved. The former has a black streak along 

 the lower part of the sides, and is found over a large extent of 

 Africa, from the Cape to Abyssinia ; for O. Biessa of Riippell ap- 

 pears 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 kudu found in Abyssinia by Capt. Harris, 

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

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

 and Senegal, is without any indication of the lateral streak. 



The animal now under consideration is intermediate between these 

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

 of A. leucoryxy but its dark legs and peculiar 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 from Bombay. A 

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

 The male is now in the Collection of the British Museum. 



Oryx Beatrix. The Beatrice. 



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

 tip, annulated nearly to the tip. White ; a spot on the middle 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-brown ; end of the tail black. 



Hab. 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 

 colours. 



In form and size it resembles the true Oryx (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 oif the haunches as in the rest of 

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

 directed forwards.

Before putting forward the opinion which my observations have 

 suggested to me with regard to circulation in plants, I think it 

 indispensable to examine the forces to which this phaenomenon is
