APES, MONKEYS AND LEMURS. 
(Primates and Prosimiae), 
Of the lour man-like Apes two occur in the Malay region, 
the Orang Utan and the Gibbon. The two others, the Gorilla 
and the Chimpanzee, inhabit tropical Africa. They differ from 
the other Monkeys by being taillesf* and by their semi-erect 
attitude. 
The Orang Utan or * Mias ' ( Simla satyruA) is confined 
to Sumatra and Borneo, A number of them are exhibited* 
male, female and young ones, the males with their long and 
extremely powerful arm;> and enormous teeth, well seen in the 
skeletons, showing what formidable enemies they might be, 
{sec pi. Ill, fig, I, and pi. VI, fig. i). They live in dense 
forests, preferably in iow -lying, swampy districts, difficult of 
access. They travel deliberately and with great circumspection 
from branch to branch and tree to tree, never jumping or 
leaping, yet still progressing as fast as a man can do on the 
ground. They build their nests high up in the trees, forming 
them, wherever possible, of living branches, which they inter- 
twine, tilHng the interstices with broken twigs and leaves. 
Tile Gibbons are considerably smaller than the Orang 
Utan. They are much lighter in build and are accordingly 
much more agile, and have very long arms. The largest of 
them is the Slamang (Hyhbates syndaciyhish from the Malay 
Peninsula and Sumatra, with black fur. Us specific name is 
derived from the web joining the second and third toe. Of the 
smaller Gibbons, indiscriminately called ' Wah-wahs' by the 
Malays, the best- known are the White-handed Gibbon ' 
( Hyhbates iar} and the .^gile Gibbon f 11 ugiiis/, both occurring
