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

 still further in Pluwuclioeriis ; but in BcMriisa the upper tusks 

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

 which reason they appear to arise on its dorsal su.rface ; 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. 



Prom iStis proper the African and Malagasy Fotamochoerus, 

 including the Eed 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 above the 

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

 " horn cores " in the extinct Dinocerata. But tlie Javau Sus 

 V6r7'ucosus 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 ilajor ^ recognises five species, of which only one is from 

 Madagascar.
