SOME EAST AFRICAN PIGS 
The tusks, as a rule, do not show the development of the 
Warthog, and the upper canines are set horizontally in the 
plane of the jaw, not at an angle with it as in the Warthog. 
They are massive and thick in perfect specimens, curving 
hack to a point (more often in sows), though generally worn 
and broken in old boars. They are rough and ridged, usually 
discoloured black, and have a large wearing surface for the 
lower tusks. These latter are thick and strong and of a 
fair length — four to six inches — projecting from the jaw. 
The teeth in the adult appear to be deciduous, as in the 
Warthog. 
The figures taken from an old boar were as follows : 
T . 1-1 . 1-1 , 1-2 , 2-2 
Incisors - — r ; canines - — r ; premolar - — - ; molars 
1-1 ’ 1-1 ' x 2-2 ' 2-2

Though it is doubtful whether this latter specimen did not 
belong to another species of Giant pig. 
In the adult the grinding surfaces are nearly flat, only 
slightly tubercular, but in immature specimens they are strongly 
ridged. 
In regard to the habits of the Giant pig, it usually lives 
in dense forest or bamboos, making runs through the under- 
growth, though, according to several observers, it has been 
seen crossing from one patch of forest to another. It is a 
gregarious animal, going at times in large sounders, though 
sows with young and old boars separate out. It has been 
observed, or rather heard, and the tracks afterwards seen in 
very large mobs, though repeatedly a pair or a single adult 
have been met with. 
It moves about in the early morning and evening and 
usually sleeps during the heat of the day. When asleep its 
snores are very audible, though, owing to the thick undergrowth, 
it is seldom seen. The places chosen for rest are generally 
under a half-fallen tree which has become covered with creepers 
and forms a sort of vegetable cave. In these places the 
female has her young, which consist of from two to six.
