THE REDISCOVERED COUNTRY 331 



rocky side hills; and the little animals leaped from one rock 

 to the other entirely satisfied. 



30. Roberts' gazelle (gazella gtanti rohertsi). — Quite 

 common between Oliondo and Olgoss. Cuninghame re- 

 ports it around Ikoma. None at all in the immense game 

 herds south of the Bologonja. 



31. Thomson gazelle {gazella thomsoni). — Nowhere 

 abundant, and apparently very local. Many sections well 

 adapted to "Tommies" are quite devoid of them. Never- 

 theless saw specimens as far west as Walioba's and as far 

 east as the plateau above N'digadigu. It would be in- 

 teresting to know why there are not more gazelles in this 

 country. Carry very large heads. I am doubtful of the 

 new subspecies nasalis. I have two heads from the region 

 of its habitat, neither of which possess the alleged dis- 

 tinguishing black patch across the nose. 



32. Impalla {aepyceros melampus suara). — Common. 

 Carry very large heads. 



33. Dik-dik {rhynchotragus Mrki cavendishi). — We found 

 this animal very local in its distribution. 



34. Rhinoceros (disceros hicornis hicornis). — Common 

 in the mountains between the two protectorates, where 

 their trails helped us greatly; but unusually scarce in the 

 new country. They have been much hunted there by 

 Wanderobo, who take their horns. 



3 5 . Zebra {equus quagga granti) . — Common everywhere ; 

 but not so common as the topi or wildebeeste. Seem in this 

 country rather to prefer cover to the open plains. They 

 are there practically invisible (see discussion elsewhere). 



36. Elephant (loxodonta africana capensis). — In the
