grand beasts, they looked very black in colour ; and on the 20th 

 of April some of our party came on a large herd between Jebel 

 Ahmed Agar and Long Tom. 



Bubalis sp. inc. 



There is not yet enough material collected to ascertain the 

 proper specific name of the Hartebeest of this region ; the 

 specimens I have seen seemed to me to be probably B. jaclsoni. 



A few Hartebeests were met with some miles north of Eenk, 

 and also on the Bahr-el-Ghazal ; they were usually among herds of 

 Damaliscus Hang. 



Damaliscus tiang (Heuglin). 



This Antelope was met with, frequently in large herds, on 

 the White Nile from about a day's steaming to the south of Jebel 

 Ain to near Lake No, and also on the Zeraf and Ghazal rivers. 

 Major Gwynn, D.S.O., E.E., told me he saw the Tiang on the 

 Sobat 70 or 80 miles from its joining the White Nile, but none 

 on the Upper Sobat. 



The horns of different individuals vary very little in length, the 

 largest male horns I have noted were 19| inches along their front 

 curve. 



COBUS DEFASSA (Eiipp.). 



This Waterbuck was met with along the White Nile to the south 

 of Jebel Ain, and on the Zeraf and Ghazal rivers. 



Cobus leucotis (Licht. et Pet.). 



The White-eared Kob was met with along the White Nile from 

 some distance north of Jebel Ahmed Agar southwards to Lake No, 

 and on the Zeraf and Ghazal rivers ; it also occurs on the Sobat. 

 Often seen in large herds : the old bucks have beautiful glossy black 

 backs ; the young bucks are reddish like the does. 



Cobus thomasi Neumann. 



Captain E. M. Sanders, Worcestershire Eegt., showed me the 

 skin, skull, and horns of an Antelope he had shot, early this year, 

 between Jebel Ain and Eenk, which exactly agrees with the 

 description of this species in the ' Book of Antelopes ' (ii. p. 131, 

 pi. xxxix.). 



Cobus mabia Gray. 



Mrs. Gray's Waterbuck was only seen on six different days, on 

 the Babr-el- Jebel, Bahr-el-Ghazal, aud on the White Nile between 

 Lake No and the mouth of the Bahr-el-Zeraf ; usually in very 

 small herds, twenty was the largest number of individuals seen 

 together. We met with this species only in swampy land, 

 intersected by khors full of water, that a man cannot get about in 

 without risk of being bogged or attacked by crocodiles. The wide
