THE GAZELLES AND THEIR ALLIES 591 



with the white basal portion of the tail, the terminal half 

 ot which is black. The rump area is bordered in front by 

 a dark bistre pygal stripe one-half inch wide. The flanks 

 show a very slight indication of the flank band, which is 

 set off by a lighter band of light buff bordering the broad 

 band of pinkish-buff above along middle of body. The out- 

 side of the legs is pinkish-buff, like the sides ; and the hoofs in 

 front are bordered by tufts of brown hair. The under-parts 

 and the inside of the legs and the lower throat are silky white. 

 The top of the head and the median line of the snout is cinna- 

 mon-rufous, and the middle of the snout is marked by a large 

 clove-brown blotch. There is a grayish border of hair about 

 the horn bases, and a blackish blotch above the eyes. The 

 sides of the face are marked by a broad white band above the 

 eye extending forward to the dark snout spot, and bordered 

 below by an ill-defined, narrow, dusky-cinnamon streak from 

 the eye to the muzzle. The orbital area is white with a 

 bistre-brown supraocular spot extending to the horn bases. 

 The tip of .the snout is pale pinkish-buff. The lips and chin 

 are white. The forethroat is white like the chin, but the 

 midthroat is pinkish-cinnamon like the nape. The ears are 

 pinkish-cinnamon, bordered at the tip by bistre, and the in- 

 side and a spot below the base is white. The adult female re- 

 sembles the male closely in general coloration with the excep- 

 tion of the sides, which are marked by a broad flank band 

 bordered above and below by an equally wide band of pinkish- 

 vinaceous distinctly lighter than the cinnamon of the back. 

 The dark pygal band is much wider than in the male. 

 Newly born young are different in color from the adults, but 

 the color pattern is quite similar. The dorsal color is drab- 

 gray lined sparingly by black, and the hind legs are similar, 

 but the forelegs are more buffy. The head markings of the 

 adult are indicated, but the white areas are suffused with 

 buffy and do not show much contrast. The crown of the head 

 is buffy, not rufous, as in the adult. The dark flank band 

 is much less distinct than in the adult female, and is mixed 

 largely with buffy and does not show the light band below 

 separating it from the white of the belly. The white rump 

 patch is only indicated, being narrow and separated on 

 the median line by the color of the back extending onto the 

 tail, and is not pure white, but suffused with buffy. The
