the hindmost is scarcely larger than the penultimate. This lower jaw is 

 that of a fully grown boar, whose hindmost molars had long been brought 

 into wear : in the other the hindmost molars are fully developed, but are 

 not abraded. 



Of the sow, there are three skulls of fully adults, with the hindmost 

 molars worn ; but one only has the lower jaw : in this, the upper plane 

 of the occiput, where narrowest, is only | in. ; being in the two others 

 1^ in. : the series of grinders is seven above and below; the tusks small, 

 as in S. ikdicus. In other respects they resemble the boar skull, except 

 in being smaller : length, from occiput to tip of intermaxillaries, 9| in.; 

 and greatest width, at the zygomata, 4 in. 



From the size of the skull of the adult boar, it may be estimated that 

 this animal would not exceed 15 in. in height, if indeed it is even so 

 high at the shoulder. The skull is much less elongated anterior to the 

 orbit than in ordinary Swine, that portion occupying somewhat less than 

 three-fifths of the entire length. Profile a little concave anterior to the 

 eyes, the forehead bulging into a convexity. 



It is probable that the same species inhabits the Cocos islets, lying 

 north of the Great Andaman, and also the group of the Nicobars to the 

 south ; though on the Great Coco it would appear that Hogs have only 

 been recently introduced by the Burmans, and may therefore be of a 

 domestic race derived from the continent. I have long had reason to 

 suspect that the Hogs of at least the Andaman islands would prove to be 

 of a peculiar species, and therefore called Dr. Liebeg's attention particu- 

 larly to the subject. The Eev. J. Barbe describes the Nicobar Pigs as 

 being apparently derived from the Chinese, and says nothing of their 

 being of a diminutive size :* moreover they appear to be domesticated ; 

 but so, I believe, are a few of the Sus papuensis in N. Guinea. Pro- 

 ceeding to the south and east, according to Dr. S. Miiller, the Sus vit- 

 tatus inhabits Sumatra, with Java and Banka; S. verrucosus also inha- 

 bits Java ; S. barbatus, Borneo ; S. celebensis, besides the Babarussa 

 (which is also in Bum and Ternate), Celebes ; S. timoriensis, Timor and 

 Itotti ; and S. papuensis, New Guinea : a goodly series of wild swine, 

 to which we now add the S. andamanensis, which needs comparison most 

 with S. papuensis. 



The wild Hogs of the mainland of Asia have not yet been properly 

 determined. They are found at all habitable elevations, and in all climates^ 



* J. A. S- XV, 352. In Mr, H. Busch's ' Journal of a Cruise amongst the 

 Nicobar Islands,' it is remarked that, in Teressa, " the jungle abounds with wild 

 Pigs, which afford the islanders both sport and provisions."
