akirii^ the hack. There is a specimen iVom Singapore islainl, 
shot and presented by Mr. W. T. Batten, in 1889, The young 
ones are marked by stripes along their sides, similarly as the 
young Tapir. Closely allied to it is the Banded Pig {Susvittaius}, 
with a white streak on either side of its face, occurring in 
Sumatra, Java, Borneo and the smaller ndghbouring islands. 
The specimen exhibited is from Pulo Ungar, presented 
by Dr. Abbott in 1993. Neither of these two pigs has any 
warts on its face. The second group has its type in the 
Bearded Pig {Sus burbaius), from Sumatra and Borneo. It has 
a thick beard at the back of its chin and a substantial wart on 
either side of its face, the wart bearing a thick tuft of bristles. 
The skull is very much elongated. A stuffed specimen, a 
skeleton and several skulls from Baram, Borneo, all obtained 
through Dr. Charles Hose, are exhibited. Very similar to it is 
the ' Nang Oi * (Sus oi), of wich a huge specimen is shown from 
Pulo Battam, an island to the South of Singapore. It was shot 
and presented by Mr, J. Romenii in 1905. The beard and 
the single wart on either side of its face are well marked,— The 
third group includes the Warted Pig (Stis verrucosus), from Java, 
of which varieties occur in Borneo, Celebes and the Philippines. 
It has three warts on either side of its face. Its skull is not 
specially elongated. 
To show how the domestic Pig differs from the wild one, 
the skeleton of a Boar. English breed, is exhibited, which was 
presented in 1907 by Dr. Lim Boon Keng and Mr. Seah Eng 
Tiong, on behalf of the Singapore Planting Co. Its skull shows 
an entirely different configuration from that of the Bearded Pig 
which is placed alongside. 
After the true Malay Pigs follows closely the Bablrusa 
(Bahintsa at/ums), peculiar to Celebes and Burn Island. The 
Malay name signifying * Deer-Pig ' is due to the upper tusks of 
the boar being enormously developed and being bent upwards 
and backwards. But a comparison of its skull with that of a 
typical pig (e.g. of the Bearded Pig) shows what little difference 
there really is between the two. Both have a bony protuberance 
on either side of the upper jaw from which the upper tusks 
spring. But whilst in the case of the pig the tusks are directed 
downwards and forwards (see pi. VI, fig. 3), they sweep 
upwards and backwards in the Babirusa. (see pi VI, fig. 2). 
However, in the living Babirusa where the base of the tusk is 
hidden within the skin of the snout, there is the deceptive 
appearance of the tusks springing from the roof of the 
mouth.
