Young probably without stripes. The genus is regarded by 

 Stehliu as related to Sus vcrrucosiis. 



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



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

 dontism " of the molar teeth of the Suina {supra, p. 305), is 

 of opinion that Bahirussa is nearly related to the selenodont 

 genus Mcrycopotamus, 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.
