considerably lengthened and laterally compressed. The 
length of its body is from twelve to fifteen inches, and 
its tail when entire, measures quite as much. The fore- 
head, which is strongly wrinkled, is nearly naked, and 
the whole of the face is entirely destitute of hair. That 
of the upper parts of the body is of a uniform yellowish 
gray, the under surface deriving a bluish tinge from the 
skin, which is but thinly covered. Its native country is 
the east of Asia. 
The right hand figure represents the Chacma, or Pig- 
faced Monkey, one of the true Baboons,. whose generic 
characters will be found in the succeeding article. The 
forehead of this species is remarkably depressed, and 
the nose much prolonged. Its general colour is dusky, 
approaching to black. Its body measures from two to 
three feet in length; but the tail is short, and does not 
reach the ground when the animal stands upon ail fours. 
It is a native of Africa, and was formerly very trouble- 
some in the neighbourhood of the Cape. 
Both these animals, although lively and _ tolerably 
good humoured when young, become mischievous in 
their dispositions and disgusting in their habits as they 
advance in age. The voice of the latter closely resembles 
the bark of a dog.
