 chcerus and Phacochwrus, the molars being of the brachyodont 

 type of those of the former, while the upper canines are

Dentition : i. %^, c. -J-, p. f , m. f = 32 or 34 ; outer lower 

 incisors frequently shed early, and in some instances perhaps 

 never developed; upper canines of males very large and 

 thick, with facets worn on their lower surfaces by the attrition 

 of the lower pair, so that their summits remain more or less 

 nearly entire ; last molars in each jaw brachyodont and 

 normal in structure; face with a pair of large fungus-like 

 warty growths below the eyes ; ears relatively small and not 

 distinctly tufted ; terminal disc of muzzle relatively large ; 

 coat very coarse, sparse, and uniformly dark-coloured ; 

 prenasal ossicle welded to nasals ; occipital surface of skull 

 broader and lower than in Potamochcerus ; forehead wide and
