206 CLASS MAMMALIA. 



a small Jachrymary sinus ; the ears are above six inches 

 long, and the tail is short, and terminated by a tuft. Ex- 

 actly upon the knees, there are brushes of a peculiar struc- 

 ture, being formed of two rows of stiff bristly hairs, per- 

 pendicular upon the edges of the joint, and turning in- 

 wards, which meet and lie close on the middle of the knee. 

 The head is white, with two spots of bright rufous hair 

 at the base of the horns, descending on the forehead to the 

 commencement of the chaffron ; the ears inside, and at the 

 base of the outside, are white, from the middle upwards 

 rufous, and the tips black ; the neck, shoulders, and back, 

 to the loins, are whitish rufous, darkest on the neck, but 

 leaving a white spot on the throat ; the rest of the body, 

 breast, limbs, and tail, excepting a rufous spot on each of 

 the fore shanks, are milk-white, so that in this species the 

 saddle-shaped space on the back differs from the former in 

 the colours being reversed ; the tail is terminated by a 

 tuft, but does not reach below the hams. 



The female is a little smaller ; the horns are less curved, 

 particularly at the points, which, in the male, bend strongly 

 to the front : the rufous colouring is also paler, and there 

 is a little blackish-gray upon the larynx. We found only 

 two mammas in this species ; the inguinal pores were 

 large, naked, and bright yellow ; the spurious hoofs very 

 small, the pasterns high, the true hoofs small, low, 

 pointed, and black *. This beautiful species resides on the 

 barren wastes of Nubia, where the specimens were pro- 

 cured by M. Ruppel, and sent from thence to the Museum 

 of Frankfort. 



The Swift Antelope. (A. Dama.) Count de Buffon 

 described this species under the name of Nanguer, from 

 a skin brought by Mr. Adanson from Senegal. The speci- 



* With the haste of a traveller I omitted to note the number 

 of incisor teeth, but believe they are as usual eight. If Pallas 

 be correct respecting Dama, this would constitute a difference.
