ch. xi] SPECIES OF GAZELLE 
and the silver moonlight flooding the reaches of dry 
grass ; it was so bright that our shadows were almost 
as black and clear-cut as in the day. On reaching 
camp I would take a cup of tea with crackers or ginger- 
snaps, and after a hot bath and a shave I was always 
eager for dinner. 
Scattered over these flats were herds of zebra, oryx, 
and gazelle. The gazelle, the most plentiful and much 
the tamest of the game, were the northern form of the 
Grant’s gazelle, with straighter horns which represented 
the opposite extreme when compared with the horns of 
the Roberts’ type which we got on the Sotik. They 
seemed to me somewhat less in size than the big gazelle 
of the Kapiti plains. One of the bucks I shot, an 
adult of average size (I was not able to weigh my 
biggest one), weighed one hundred and fifteen pounds ; 
a very big true Grant’s buck which I shot on the Kapiti 
plains weighed one hundred and seventy-one pounds. 
Doubtless there is complete intergradation, but the 
Guaso Nyero form seemed slimmer and lighter, and in 
some respects seemed to tend toward the Somaliland 
gazelles. I marked no difference in the habits, except 
that these northern gazelle switched their tails more 
jerkily, more like tommies, than was customary with 
the true Grant’s gazelles. But the difference may have 
been in my observation. At any rate, the gazelles in 
this neighbourhood, like those elsewhere, went in small 
parties, or herds of thirty or forty individuals, on the 
open plains or where there were a few scattered bushes, 
and behaved like those in the Sotik, or on the Athi 
plains. A near kinsman of the gazelle, the gerunuk, 
a curious creature with a very long neck, which the 
Swahilis call “ little giraffe,” was scattered singly or in 
small parties through the brush, and was as wild and
