 along the upper surface of the latter as far as the 

 occiput. The black may extend on to the legs. 



Enormous herds of these sheep are kept in the 

 Hedjaz district and other parts of Southern Arabia. 

 Nubia, Kordofan, and Sennar are the home of 

 a breed of fat-rumped sheep characterised by the 

 development of a short mane on the necks of the 

 rams, and accordingly regarded by Dr. Fitzinger * 

 as a cross between the Hedjaz breed and the 

 African maned sheep. ^ As compared with the 

 Hedjaz breed, these sheep are characterised by 

 the greater convexity of the nose, and the deeper 

 channel between this and the forehead, as well as 

 by the constant presence in the rams of short 

 curling black horns closely applied to the head. 

 The dewlap is bigger in both sexes and extends 

 down to the chest ; the back is markedly hollow, 

 and the croup less elevated. The tail, which has 

 the same formation as in the Hedjaz breed, and 

 shows a double curve, is freer from the fat-masses, 

 more especially in the ewes, in which it reaches to 

 the middle of the thighs, and is less distinctly 

 divided on the under side into two portions by a 

 longitudinal groove. In the rams a short mane 

 clothes the neck and withers, and in ewes the white

 back of the neck on to the forehead ; but in other
