_ ANTELOPES 307 
‘feidy easy to stalk. When alarmed they have a curious habit 
of bounding up into the air, and present an amusing sight when 
many of them are jumping about at the same time. Incommon 
with many other bush-loving antelopes, they often have diffi- 
culty in making out the direction whence a shot comes, 
and if the sportsman takes care to keep out of sight he may 
get several shots before they finally make off. The impala isa 
grass feeder. 
LITHOCRANIUS WALLERI 
The Walleri is plentiful on the banks of the Tana river, 
and there are a fair number at Merereni. It is also found 
in the Kilimanjaro district. The 
East African walleri is very much 
smaller than the one found in the 
Somali country. There is no mis- 
taking this antelope for any other, 
on account of its extraordinarily long 
and thin neck, which in a fully adult 
buck, killed by myself at Merereni, 
was only fo ins. in circumference ; 
two females measured 7 ins. each 
round the neck. When walking and 
seen at a distance they look not un- 
like pigmy giraffes, as they carry their = 
long necks stretched out at an angle. 5 The Walleri 
They frequent the open bush fringing 
the outskirts of dense thickets, into which they at once retreat 
on being disturbed. Their note of alarm is a low short ‘buzz!’ 
The Walleri is essentially a bush feeder. At Merereni I once 
watched a doe feeding on a small-leaved bush, not unlike 
the privet in appearance, and several times saw her rear up on 
her hind-legs, bend down a branch with her forelegs, and 
feed on the leaves in this upright position like a goat. This 
quaint-looking little antelope, like the bush-buck, will haunt 
one particular spot, and may be seen in or quite near to
