1900.] FAUNA OP THE WHITE NILE. 955 



curling horns of 0. maria look very fine, but the gait of the animal 

 when galloping over the rough ground is very ungainly and 

 awkward looking. 



Cervicapra bohor (Kiipp.). 



The Bohor Eeedbuck was met with near Jebel Ahmed Agar, 

 and on the Zeraf and Ghazal rivers ; singly or in parties of one 

 buck and one or two does. I think this species the most graceful 

 of all the White Nile antelopes. 



OUREBIA MONTANA (EUpp.). 



Oribis were met with near Kaka and Jebel Ahmed Agar, singly or 

 in pairs, in the long grass and bush. Both sexes are coloured 

 alike : that is, rich reddish fawn above, paler at the sides, aud 

 white underneath ; there is no black at all on tail, face, or sides. 



GrAZELLA RUFIFEONS Gray. 



The Bed-fronted Gazelle was met with on both banks of the 

 White Nile from Abu Zeit to Kaka. 



Colour (sexes alike). Above bright rufous fawn, below pure 

 white, a well-defined and conspicuous black stripe on the side of 

 the body, last three-quarters of tail black : no black marks on face. 



HlPPOTEAGUS EQUINUS BAKERI (Heugl.). 



Baker's Boan Antelope, locally known as the " Abu Aroof," was 

 met with near Jebel Ahmed Agar and on the Bahr-el-Zeraf. 



Tragelaphus sp. inc. 



A large long-horned species of Bushbuck was observed by 

 Lieut. Drury, B.N., on the Bahr-el- Jebel. 



Family Suidje. 



PHACOCHC3RUS AFRICANUS (Gm.). 



Wart-hogs were met with only on the 22nd April, some miles 

 south of Jebel Ain. 



Family Hippopotamus. 



Hippopotamus amphibius L. 



The Hippopotamus was first seen a little to the south of 14° 

 North latitude, but did not become plentiful till south of Abu Zeit 

 ford : these Northern animals were rather angular and starved- 

 looking. Except in that part of the Bahr-el- Jebel where the sudd 

 blocks were, we found the Hippopotamus very numerous wherever 

 we went on the White Nile, Zeraf, Jebel, Ghazal, and Arab rivers, 

 particularly in Lakes No and Ambadi. Between the 13th March 

 and the 23rd April we saw Hippopotamuses on 34 days out of 42.
