male. In the Wild Boar there is a hint of this, which is carried 

 still further in PhacocJiorrus^ ; but in Bahirusa the upper tusks 

 turn upwards before they leave the substance of the jaw, for 

 which reason they a])pear to arise on its dorsal surface ; the 

 lower tusks are nearly as long. It has been found that the 

 young of this Pig are not striped as are those of other Pigs. 

 By means of the curved upper tusks this animal has been said by 

 old writers to suspend itself to branches of trees, just as does by 

 his downwardly-projecting tusks the male Chevrotain ! There is 

 but one species, B. alfurus. 



From Bus proper the African and Malagasy Potamochoerus, 

 including the Bed Eiver Hog, is barely separable generically. 

 Their principal claim to generic distinction lies in the existence 

 of a horny outgrowth arising from a bony apophysis al)Ove the 

 canina in the male. These have been compared to the osseous 

 " horn cores " in the extinct Dinocerata. But the Javan Sus 

 verrucosus shows at least the beginning of a similar modification. 

 The popular name of the animal is derived from the fine rufous 

 colour of its pelage, not seen, however, in all the species. Dr. 

 Porsyth INIajor ^ recognises five species, of which only one is from 

 Madagascar.
