THE MALAYSIAN UNGULATES.

Wild Pigs are found almost all over the Old World as far 
East as New Guinea. In many parts of the world such as America 
and New Zealand domesticated pigs have been turned loose and 
have formed wild races. But strictly speaking the wild pigs are 
confined to the Old World. In the New World they are replaced 
by another Family of Pig-like animals called Peccaries. A third 
Family of the Pig-like group contains the Hippopotamus which is- 
now confined to Africa, although fossil remains from England, the 
Himalayas and Burma show that at one time it had a wider range 
and may possibly even have extended into Malaysia, 
The wild pigs of Malaysia are broadly separable into three 
species : — 
a Without warts on the face; young striped , . S, serofa. 
a 1 With one large bristled wart on each side of 
the face; cheeks fringed with long hair; 
skull elongated ; young striped .. . . S t barbatu*. 
a* With three small warts on each side of the 
face; young uniformly coloured , , . . *9, rernmwiM. 
A great number of pigs have been described from ditferent 
parts of Malaysia, and considerable uncertainty still continues as 
to the relative values of the different “species” and “ subspecies ” 
and as to their relationship one to the other. 
A distinction between wild pigs and domesticated pigs, given 
by Lydekker, is the straightness of the profile in the former com- 
pared with the more or le-s concave profile in the latter. 
The origin of domesticated pigs has been debated at consider- 
able length : the most probable view apparently being that domesti- 
cated races in different parts of the world have been derived from 
the wild pigs of the same areas. But crossing between different 
domesticated races no doubt has taken place on a considerable scale. 
One remarkable pig, although outside the Malaysian sub-region 
(as defined for the purposes of tins Museum) is the Babirusa of 
Celebes. It is almost hairless. In the male the tusks of the upper 
jaw come right through the skin of the face, instead of protruding 
from the jaw. Tliey are enormous])* developed and curled upwards 
and backwards over the face as if in protection of the eyes. The 
lower tusks are also strongly developed having a similar curved 
sweep upwards and backwards. It is not known of what use they 
are to the animal in this form (see Plate V).

The Malaysian Wild Pig has been generally regarded 
as a distinct species, but in accordance with more modern 
views and perhaps a broader conception of the term “species,” 
it is not unreasonable to regard it as only a geographical race 
of the Wild Boar of Europe which is still abundant in many
