down to the river-bed, and is also seen on the barer hill-tops.”’ The 
presence of this hill-loving species in the Blue Nile Valley west of the 
Abyssinian hills would certainly be extraordinary, and I cannot but 
think that on reaching this low flat country Lord Lovat mistook the 
Oribi or the Duiker for the Beira which he had found in the higher 
land through which he had just passed. At all events we found no 
sign of it between Roseires and Fazogli during our trip.

Specimens from the eastern Sudan are currently referred to this 
species. We met with it in the Blue Nile Valley only, and in but few 
places. Cotton (1912) records seeing one at Bados and it is likely 
that this is about as far north as it occurs on the Blue Nile. Above 
this point we saw a few at Magangani, and near Gebel Maba, and 
some numbers near Fazogli. This is a very sedentary animal, and we 
repeatedly found what were presumably the same individuals near the 
same thickets day after day. At Magangani we saw a few along the 
edge of a great sea of elephant grass between the river and some 
undulating ridges, but at Fazogli they frequented a considerable area 
of alternating ridges and small gullies, which with their thickets and 
clumps of grass or small palms were admirable hiding places. Dr. 
Phillips spent much time here observing them, and found them most 
crafty and watchful. They were usually seen in the early part of the 
day singly or in pairs, and had a way of hiding in clumps of vegetation 
to watch the intruder or slinking’ adroitly off under cover of an inter- 
vening bush if followed. Those living near this native village were 
no doubt much hunted and had become extremely adept at keeping 
out of sight.
