Quite different is it on the upper part of the Dinder. On reaching 

 the stretches where the great open 'meres' begin, shortly below Um 

 Orug, we found them really common. Cotton (1912) found them com- 

 mon on the Galegu, but saw only a few on the Dinder, below the junc- 

 tion of these two streams. He adds that they are not found on the 

 Rahad, but are common on the Setit. We first found them a short 

 distance above the Galegu, at Beit el Wahsh, where a few were feeding 

 on a large ' mere,' and beyond this point we saw small numbers, usu- 

 ally feeding in similar places. At Um Orug they were plentiful and 

 remarkably unsuspicious. Dr. Phillips at one spot came upon a 

 Waterbuck that allowed him to walk entirely around it at a short 

 distance. Another that he obtained must have recently escaped 

 from a lion as its back was deeply scratched and its belly so injured 

 that the intestines protruded through the open wound. Shortly 

 above the Galegu junction we saw a lion stalking an old Waterbuck in 

 the open sandy bed of the river at about midday. On one large 

 'mere' at Um Orug, Dr. Phillips saw ninety-seven Waterbuck at one 

 time, quietly feeding, and later that evening we found others there, 

 grazing by the half moonlight. This with the Reedbuck was usually 

 the last of the antelopes to take fright when several species were 

 feeding together. During the heat of the day they are apt to rest 

 under the shelter of the thorn trees, and it is common to see them in 

 small parties consisting of a buck and two or three does. 



Ourebia MONTANA (Cretzschmar). 

 Abyssinian Oribi.

 Saugeth., 1826, p. 11, pi. 3. 



In his original description of this species, Cretzschmar gives its 

 known range as Bahr-el-Abiad and the mountains about Fazogli 

 (spelled "Fazuglo"). The latter are merely hills, however, so that 

 the name " 7nontana" is somewhat misleading. This is the common 

 antelope along the Blue Nile and is called by the Arabs "ghazal." 

 In many of its habits it corresponds to our Virginia Deer. It inhabits 

 the edge of the tall grass jungle along the river bank, or the bushy 

 tangles in which it finds a safe retreat. W'e also met with it on the 

 slopes of the 'gebels' or hills. It is watchful and resourceful, yet 

 hardly to be considered shy, so that it seems well adapted to survive
