Notes and 
in this region. The reason, as Mr. Pocock 
points out, is now apparent. These animals 
inhabit a more open country than many 
of the other forms of zebra, and conse- 
quently when lying down are exposed to 
a much stronger light, so that they require 
the whole of the lower line of the body 
to be lightened when in this posture in 
order to do away with the effect of the 
deep shadow cast upon them; hence the 
light colouring of the buttocks. 
The sable antelope affords another notable 
instance of the same type of colouring, 
the pure white of the buttocks forming a 
continuous line with that of the under-parts 
when in a recumbent posture, and thus no 
doubt neutralising the effect of the black 
upper-parts and of the shadow cast by the 
body. At the same time, the white rump- 
blaze in this and many other species pro- 
bably also serves the purpose of a recogni-

tion-mark, so that it has a double function. 
It would be imteresting to have an animal 
with this type of colouring stuffed m a 
recumbent position to illustrate the purpose 
of the rump-blaze.

easier than to obtain photo- 
eraphs of the white rhinoceros, for these 
ereat beasts (second only in bulk to the 
elephant) were in the habit of coming quite 
close up to the waggons of the sportsmen, 
with the apparent intention of attacking 
them. Probably this was due to the creatures 
mistaking the waggons for some monstrous 
animal which had invaded their territory.
