Very large, heavily built antelopes resembling Boocercus 

 in the tufted tail and the presence of horns in both sexes, 

 but distinguished by the horns being strongly keeled, and 

 forming a closely twisted screw-like spiral, on which the 

 front keel makes one complete turu^ the tips being black ; 

 as well as by the presence of a more or less strongly 

 developed bushy frontal tuft, and of a heavy dewlap, fringed 

 with long hair. In females the horns are longer, thinner, 

 and less strongly keeled, while the dewlap is wanting and 

 the frontal tuft less developed. 



The range includes the greater part of Ethiopian Africa, 

 exclusive of the equatorial forest. In the Phocene the 

 group was represented in India by the so-called T. latidens,
