THE GAZELLES AND THEIR ALLIES 611 



scrub-covered country along the Northern Guaso Nyiro. It 

 was as wild and wary as the gazelle of the neighborhood was 

 tame. It was always found singly or in small parties, some- 

 times near the river, more often in the driest regions; and 

 the gerenuk, which lived away from the neighborhood of 

 water, certainly did not drink at all. They browsed on the 

 twigs and withered leaves of the bushes and low thorn-trees. 

 The stomach contents of two or three specimens included 

 leaves of the tooth-brush bush, Salvadora persica ; wait-a-bit 

 acacia leaves, A. mellifera ; and berries of nightshade. Sola- 

 num campy lac anthum. All their attitudes are characteristic 

 and unlike those of other antelopes. They frequently rise 

 on their hind legs to snatch some bunch of leaves which is 

 beyond the reach of their long necks, and when alarmed 

 they sneak off at a trot through the bushes with the head 

 and neck stretched straight in front of them. They were 

 quite indifferent to heat, and we saw them feeding at noon 

 as often as in the morning or evening. They were some- 

 times found in the barren, open plains, crossing from one 

 patch of scrub to another, and if surprised in such a place 

 they would break into a gallop. More often they were 

 found in the rather thinly bushed tracts — the bushes at 

 the time of our visit being well-nigh leafless — and then they 

 preferred to skulk and hide. 



The dorsal color of the body is uniform cinnamon- 

 rufous and covers the back like a short blanket, being 

 sharply defined along the middle of the sides by a band of 

 lighter color, or buff-pink. The buff-pink extends over the 

 middle and lower sides, and is defined in its turn sharply 

 against the white under-parts. Upon the sides of the neck, 

 however, there is no sharp contrast between the color of 

 the nape and that of the throat. The limbs are uniform
