APES AND MONKEYS 
extraordinary height of the crown of the head is well exhibited in our figure of the 
head and shoulders of an immature individual, the whole of this part of the head 
being curiously shortened and compressed from back to front. In the immature 
animal, of which the head is figured, the jaws are not very prominent, but they 
become much more projecting in old males. The bridge of the nose is generally 
much depressed and flattened, but the whole nose is generally larger than in the 
chimpanzee and gorilla, and not so much expanded at its termination, the wings of 
the nose being arched and narrow, and the small oval nostrils separated from one 
another by a narrow partition. The mobile lips are usually comparatively smooth

and thin, the upper one being characterised by its great length and breadth. In the 
adult of the orang, as shown in our illustration, the neck is surrounded by a kind 
of collar formed of folds of skin containing an internal cavity communicating with 
the larynx or upper expansion of the windpipe. In some very old males these 
pouches attain enormous dimensions, and by no means add to the personal beauty 
of their owner. The ear is small and well formed, and it is much more human 
than that of the gorilla. Frequently the sides of the cheeks of the males have a 
warty protuberance, or callosity. 
The body is by no means so powerfully built as that of the gorilla; and the 
sloping and stooping shoulders and extremely prominent abdomen make the whole 
shape of the animal ungainly in the extreme.
