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.

According to Cotton (1912, p. 55) this handsome antelope is not 

 now to be found on the Setit, Atbara, or Rahad Rivers, although it is
