THE CHACMA.

Black Colobus. Both these monkeys are possessed of crests which 

 give a peculiar character to the whole aspect. That of the Black 

 Colobus, however, is reverted forward, and curves to a poiut over the 

 forehead, while that of the animal before us rises from the head and 

 bends backward over the neck in a manner not unlike that of the 

 cockatoo. 



Like the Magot, the Black Macaque has been called an ape by 

 some writers, and a baboon by others, on account of the apology for 

 a tail with which its hinder quarters are terminated, but not decor- 

 ated. It is an inhabitant of the Philippines and the neighboring 

 countries. 



BABOONS, OR DOG-HEADED MONKEYS. 



A well-marked group of animals now comes before us, popularly 

 known by the name of Baboons. 



One distinguishing characteristic of these creatures is that the 

 nostrils are situated 

 at the extremity of 

 the muzzle, instead 

 of lying nearly flat 

 upon its base, and 

 just under the eyes, 

 as in the apes and 

 other quadruman- 

 ous animals. The 

 muzzle, too, is pe- 

 culiar in its form, 

 being, as it were, 

 cut off abruptly, 

 leaving a round and 

 flattened extremity, j- 



Of the Dog-head- - 

 ed Baboons, the spe- 

 cies which is most 

 celebrated for its feats of prowess is the well-known animal called the 

 Chacma, or Ursine Baboon. 



This animal, when it has attained its full age, equals in size a large 

 mastiff" or an ordinary-sized wolf; while, in bodily strength and 

 prowess, it is a match for any two dogs that can be brought to at- 

 tack it. 



The Chacma is a most accomplished robber, executing his burgla- 

 ries openly whenever he knows that he will meet with no formidable 

 opposition, and having recourse to silent craft when there are dogs to 

 watch for trespassers, and men with guns to shoot them.
