Remarlis. — This species is readily distinguishable from the Andaman 
pig by its larger teeth. The uniform black color of the type and the 
peculiar hairing of the tail may be mere individual characters. 
The occurrence of a diminutive wild pig on the Nicobar Islands was 
noted as long ago as 1863 bj^ Blyth;^ but until the present time there 
has been no opportunity to compare the animal with Sus andanianen- 
sis. That it proves to be distinct from the Andaman swine is not in 
the least surprising, though such a possibility appears not to have 
occurred to Blyth. He says: 
The small Andamanese wild pig appears, at first, to be as isoltited in its range as 
new to science; but I have been assured of the existence of a diminutive wild pig in 
the Nicobars, additional to the huge tame swine of undoubtedly exotic origin, which 
are bred by the Nicobarians of the coasts; and I have also considerable reason to 
suspect that it exists likewise in Sumatra. 
The differences between the wild and domesticated pigs of the 
Andamans alluded to ))y Blyth were noted in considerable detail by 
Dr. Abbott.'' 
Pigs, both tame and wild [he writes] were plentiful in the Nicobars. Those in 
Kar Nicobar, and many of the tame ones everywhere, are descendents of European 
and Chinese stock, and splendid big porkers some of them are. But the wild pig of 
which I send you one skin and two skulls from Great Nicobar does not seem the 
same. It is small, about the same size as that of Bunguran Island \_Sus nalunensis], 
the males weighing about 90 pounds. I am almost sure that it has been introduced 
long ago into the Nicobars, and that it was originally Sus crislatus of the mainland, 
degenerating as the result of insularity and inbreeding. The Danes and others have 
had settlements on the Nicoljars in the last century, and an extensive trade with 
India and with Chinese junks from Hainan. This trade has been going on for gen- 
erations, and the modern big pig is the result of the new introductions mixed more 
or less with the small form. In Creat and Little Nicobar many of the tame pigs are 
precisely like the skin of the wild one which I send, and although the tame animals 
are usually larger they never equal the size of the huge European pigs of Kar Nicobar 
and the islands of the central group.
