and rump are white. The face, forehead and 

 chin are whitish fawn : the cheeks are of the 

 same ground colour but are ornamented with a 

 blackish streak, whilst a dark-coloured area also 

 occurs below the horns. This gazelle has a con- 

 spicuous white mark on the throat : its legs are 

 rufous externally, and white internally, the rufous 

 of the hind legs being continuous with that of the 

 body. Young mhorr have the horns appearing 

 as short spikes, strongly and uniformly curved 

 forwards: 1 with increasing age the horns gradu- 

 ally assume the adult shape, and become thick, 

 annulated at the base and bent strongly back- 

 wards, being finally directed forwards and upwards 

 to end in sharp points. The horns of an example 

 measured by Mr. Bennett taped twelve inches 

 along the anterior curve, and the tips were four 

 inches apart. The knees of the mhorr gazelle 

 bear small brushes of hair. 



The unsettled nature of the country inhabited 

 by this antelope has not conduced to original 

 observations on its habits, and practically nothing 

 whatever is known about it in the wild state, 

 although the animal has long been known to 

 science. Occasionally one or two living examples 

 are sent to Europe : but the species remains 



i This is well seen in the two young mhorr (labelled as Gazclla 

 dama) now in the Jardin des Plantes Museum. The head of eacli 

 animal bears two forwardly directed spikes, being about 3 inches 

 long in one animal and 1 inches in the other. These specimens came 

 from Senegal, and were acquired from M. Fronsacq.
