496 AFRICAN GAME ANIMALS 



Specimens of this race have been examined from Rhino 

 Camp, Lado Enclave, and Gondokoro, Uganda. They are 

 universally distributed in the vicinity of water and have 

 been met with by every sportsman who has visited the 

 upper Nile. Sir Samuel Baker, Von Heuglin, and Schwein- 

 furth were some of the first to record the occurrence of the 

 waterbuck in the Soudan. 



No flesh measurements are available of specimens. The 

 largest skull examined is i^^s inches in length, which would 

 indicate a somewhat smaller body size than the Uganda 

 race in which the skulls are usually i6 inches in length. 

 The longest horns recorded by Ward are a pair 33}4 inches 

 in length from the Bahr el Ghazal collected by Mr. A. L. 

 Butler, the game warden of the Soudan. Average horns, 

 however, are very much smaller, 25 inches being a good 

 adult size. The longest-horned waterbuck collected by the 

 Smithsonian African expedition was one of this race shot 

 by Colonel Roosevelt, near Rhino Camp, which measured 

 30 inches. 



Uganda Defassa Waterbuck 



Kohus defassa ugandce 



Native Name: Luganda, nsama. 



Kobus unctuosus Uganda Neumann, 1905, Sitz. Ber. Ges. Nat. Freund. 

 Berl., p. 92. 



Range. — From the western base of Mount Elgon west- 

 ward throughout Uganda to the Semliki Valley north as 

 far as the limits of the Victoria Nile drainage and south to 

 Lake Kivu. 



The Uganda defassa was described by Herr Neumann in 

 1905 from specimens shot on the Maanja River in central 

 Uganda. Speke and Grant met with this antelope in 

 Uganda and brought home with them two heads which were 

 referred by Sclater to the sing-sing defassa of Gambia. At 

 that time the preserved specimens of waterbuck were so few 

 in number that the slight color differences now used to dis- 

 tinguish the geographical races had not been detected. 



The defassa inhabiting Uganda and the Semliki Valley is 

 a short and thin haired race like the Nile defassa, from which 

 it is distinguishable by its larger body size and much longer 

 horns. The color differences with the latter are slight, the
