The head and skull lengthened absolutely, and as compared with 

 its width, as the animal increases in age, and especially as it reaches 

 adult and old age. The nasal bones of the skull elongated as the 

 animal increases in age. In the young they seldom extend beyond 

 a line even with the larger foramen on the side of the face ; but in- 

 the adult they are generally much produced behind it (P. Z. S. 

 1852, p. 131). 



The descriptions and the figures of the two jaws in F. Cuvier's 

 ' Dent. Mamm.' p. 208, do not agree ; he says there are 14 grinders 

 in each jaw, and divides them into 6 false molars and 8 molars in 

 the upper, and 2 false and 6 molars in the lower ; the 2 is perhaps 

 a mistake for 8. The front lower premolar is far from the canine 

 and second premolar ; three upper and four lower premolars com- 

 pressed ; the last grinder elongate, longer than broad. 



Fitzinger, in his monogra[)h, divides the Pigs thus, according to 

 the presence or absence of warts on the face : — 



Warts none : — Sus leucomystax, S. timorensis, S. vittatus, S. bar- 

 batus, S. cristatus, S. sennaariensis . 



Warts small, under eyes : — iS. scrofa. - 



Warts three — one large, on the mandible, covered with long bristles, 

 and a small one under the eye, and the other above the canines : — 

 S. verrucosus, S. celebensis. 



The Pigs may be divided geographically : — Europe, tS. scrofa ; 

 Asia Minor, iS. libycus ; India, S. cristatus, S. andamanensis ; Africa, 

 iS. sennaariensis ; Malay Islands, kS'. verrucosus, S. celebensis, S. bur- 

 batus, S. vittatus, S. timorensis ; Japan and Formosa, S. leucomys- 

 tax. 



f Head moderate, with three small warts, and one at the Lack 

 angle of lower jaw. Skull with the lower jaw above half as 

 long again as the height at the occiput ; concavity in front of 

 orbit deep, and narrow behind. Nape erect.
