KORRIGUM, TIANG, OR TOPI

race would have been termed the Senegal korrigum — a better title than 

 Senegal hartebeest, as it used to be always termed. 



Using the name korrigum in a wide sense, so as to include the 

 tiang and topi, this antelope may be defined as a large red-coloured 

 species of Davialiscus characterised by the single curve of the heavily 

 ridged and slightly lyrate horns, the presence of a blackish blaze on 

 the face, and (usually) similar patches on the upper part of the fore- 

 legs, hips, and thighs, which 

 extend in the form of a garter 

 on the inner sides of the limbs 

 above the knees and hocks. 

 The tail -tuft is black. The 

 height is from 48 to 50 inches. 



In the typical korrigum of 

 Senegambia and the interior 

 of West Africa {Damaliscus 

 coyriguiii iypicus), the general 

 colour is a rich full red ; the 

 black markings are strongly 

 pronounced, and include a black 

 streak given off from the face- 

 blaze running upwards and out- 

 wards below the eye ; the lower 

 portions of the legs appear to 

 be coloured like the body, and 

 the tail-tuft is large. The hair 

 has a silver -like gloss, giving 

 it a kind of " watered -silk " 

 appearance. 



The tiang {D. c. tiang), of 

 Sennar, Kordofan, and the 

 Bahr-el-Ghazal, appears to differ 



from the last by the larger amount of black on the inner side of 

 the limbs, and the bright tan-colour of their lower portions. 



The Uganda tiang {D. c. selousi) is distinguished by the bright 

 tan or chestnut colour of the muzzle and of the area around the eye 

 above the dark eye-stripe. 



The desert tiang (Z>. c. jonesi), of the upper Sudan, which is stated 

 to inhabit dry sandy tracts in place of swamps, is a plumper and browner 

 antelope than the true tiang, with no dark eye-stripe, and, it is reported, 

 no dark markings on the limbs.
