Equatorial Damaliscus 



Damaliscus korrigum 



Included under the term equatorial damaliscus are the 

 three races known to sportsmen as the korrigum, tiang, and 

 topi. They are very closely related and scarcely distin- 

 guishable notwithstanding their diverse geographical ranges, 

 which are accompanied by considerable local isolation. For- 

 merly these three forms were considered as species and dis- 

 tinct names were applied to them under the assumption 

 that they were quite distinct. Owing to the scarcity of 

 specimens in museums for comparison the real differences 

 in these forms have remained unknown. It has recently 

 been found that they are subject to a considerable degree 

 of variation in their black color markings which renders the 

 characters upon which the old species were based void. 

 Damaliscus korrigum has the coloration and body size of 

 the sassaby of South Africa from which it is distinguishable 

 by decided differences in the shape of the horns. In the 

 sassaby the horns spread outward from the head in a wide 

 curve, somewhat as in the tora hartebeest, and then curve 

 inward at the tips and are never parallel or gradually diver- 

 gent backward as in the korrigum. The equatorial damalis- 

 cus inhabits the territory south of the Sahara Desert and the 

 Abyssinian highlands from the Tana and Juba Rivers on the 

 East Coast westward through the Nile Valley and Lake Chad 

 watersheds to the West Coast and Senegal region. Three 

 geographical races may be recognized, the topi in the east, 

 the tiang in the central region, and the korrigum in the west.
