68 MALAYAN PIGS. 



synonymous, and a new species, Sus gargantua, founded by Mr. 

 Miller on the skull of a young adult male from south-eastern 

 Borneo. This, besides being the largest of known living pigs 

 (upper length of skull of young adult 570 mm., of old S. 

 bar batus 510 mm.), is further distinguished by having its ex- 

 tremely low occipital region produced backwards to a degree 

 quite unknown in others of the group. 



The members of the Oistatus group are confined to the 

 mainland and the near-by islands. It has long been thought 

 that the wild pig of the Peninsula was the same as the Sus 

 cristatus, Wagner, of India proper and when writing a note on 

 the Sumatran Sus oi for the Journal (No. 45, p. 60), I stated 

 that " only one species of wild pig is at present known to occur 

 in the Malay Peninsula and that is the animal regarded as 

 identical with Sus cristatus of India," but it appears that the 

 animal ranging from Tower Tenasserim southwards must now 

 be separated from the Indian form. It is now described under 

 the name of Sus jubatus ; and to a form from Pulo Teratau, and 

 perhaps other islands off the west coast of the Peninsula, that is 

 like jubatus but not as large, Mr. Miller has given the name 

 jubatulus. It is unfortunate however that in making into a 

 separate species an animal that inhabits a shoal-water island 

 situated close to the mainland, the author has only one example 

 to work upon. 



The pigs of the Vittatus group are purely insular except 

 one new species from the southern extremity of the Malay Penin- 

 sula. They range from the Andamans and Nicobars in the west 

 to the Natunas in the east. The typical Sus vittatus, Miiller 

 and Schlegel, inhabits the mainland of Sumatra and the Rhio 

 Archipelago form now becomes a separate species under the 

 name of rhionis. The largest known member of the group, 

 which is specially interesting as inhabiting the Asiatic main- 

 land (so that the Peninsula is now found to possess at least two 

 peculiar pigs), occurs in Johore. This is Sus peninsularis and 

 presumably the pig of Singapore Island is of this species also. 



The remaining species of this group are widely distributed. 

 On Pulo Nias, on Pulo Babi together with Pulo Tuanku and 

 lastly on Pulo Simalu, all islands of the West Sumatra chain,
