Young probably without stripes. Tlie genus is regarded by 

 Stehlin as related to Sus verrucosus. 



The range is restricted to the islands of Boru and Celebes. 



Deninger, who adopts Stehlin's theory of the " neobuno- 

 dontism '' of the molar teeth of the Suina (supra, p. 305), is 

 of opinion that Bdbirussa is nearly related to the selenodont 

 g&oMs, Merycopotamus, of the Indian Siwaliks; both genera 

 agreeing in the parallelism of the two lines of cheek-teeth, 

 the general contour and small size of these teeth, the form 

 and direction of the tusks, and certain other features.
