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 1534 inches in length, which would 
indicate a somewhat smaller body size than the Uganda 
race in which the skulls are usually 16 inches in length. 
The longest horns recorded by Ward are a pair 33^ 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

Native Name: Luganda, nsama.

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
