river, consists of so soft ground that a walking man sinks down over his ankles, but 

 I never saw any Kanganis in such places. On the southern side of Guaso Nyiri they 

 were mostly seen in places where the soil was firm, sometimes with a layer of dry 

 dust on top in which they now and then were seen rolling like horses. In many 

 localities of wide extension the plains were thickly strewn with black, sharp-edged 

 stones of volcanic origin, and even in such places the Kanganis were fully at home. 

 The soil of the thornbush country on the northern side of the river mentioned con- 

 sists of hard-packed gravel with a great amount of quartz pebbles. My experience 

 is thus that the Kangani prefers hard ground. 



The appearance of the hoofs of old specimens testifies that. The present author 

 can fully confirm by own experience A. H. Neumann's statement in » Great and 

 Small Game of Africa* (p. 89): »In stony country the soles of an old Grevy's hoofs 

 are sometimes worn almost quite flat, frog and all.» To this may be added that 

 considerable pieces may be broken from the sides of the hoofs and, although this 

 heals up again, the unevenness of the sides of the hoofs proves the hard usage they 

 have been subjected to among the sharp stones. 



Considering the altitude I have only three observations which can be referred 

 to the habitat of the Kanganis. Our camp at Lekiundu river was according to the 

 barometer 1150 m., Njoro about 750 m. above the sea level, and our camp below 

 Chanler Falls at about the same altitude as the latter.

It is connected with great difficulties to obtain adult Bush-Pigs as they are 

 nocturnal in their habits, and in day-time are hidden in the densest thickets that 

 can be found, and where it is impossible to penetrate noiselessly as well as to see 

 more than a few metres ahead. Fresh spoors were seen not far from Nairobi, in the 

 forests on Kenia, and also at Meru boma, and a couple of times I even was near 

 enough to hear when the pigs rushed away through the bushes but none was ever 

 seen. In steppe and dry thornbush country they are not to be found, there the 

 Wart-hogs take their place. 



From Mr. Klein of Nairobi I obtained a couple of Bush Pigs which had been 

 killed not far from the place mentioned. They are both fully adult specimens, and 

 resemble each other in colour. 



The whole head of an old sow (PI. IX) including even the chin and lower jaw, 

 is white, partly dirty white, with entirely black ears with rather long tufts, a black 

 patch above either eye, and a black streak above the white whiskers. The head of
