468 HOWLING MONKEYS. 



Among the Monkeys of the Old Continent a prominent place 

 should be given to the Proboscis Monkey (Nasalis larvatus}, who is 

 endowed I may not say, ornamented with a nose of the most 

 grotesque character and formidable dimensions. This species mea- 

 sures two feet from the tip of the nose to the tail, which is longer 

 than the body. His colour is a dark chestnut, but the face is marked 

 with blue and red. He belongs to Borneo and Cochin-China, where 

 he assembles in large troops, and feeds wholly on fruit. 



To Cochin-China also belongs the DOUG, a very large species, remark- 

 able for their eoat of many colours. Back, belly, and sides are of a 

 yellowish-gray ; feet black : lower part of the arms and tail, white ; a 

 collar of brown ish-purple encircles the neck ; long yellowish hairs fringe 

 the sides of the face, which is rather flat and of a yellowish bay hue. 

 He measures, when standing upright, three feet and a half to four feet. 



In South America are found the Howling Monkeys. Mr. Bates 

 describes one species, the Mycetes strumineus, which measures sixteen 

 inches in length, exclusive of the tail ; the whole body is covered 

 with rather long and shining dingy-white hair, the whiskers and beard 

 only being of a tawny hue. "The one of which I am speaking," 

 says Mr. Bates,* ''was not quite full grown. When it first arrived, 

 it occasionally made a gruff subdued howling noise early in the morn- 

 ing. The deep volume of sound in the voice of the howling monkeys, 

 as is well known, is produced by a drum-shaped expansion of the 

 laiynx. It was curious to watch the animal whilst venting its 

 hollow cavernous roar, and observe how small was the muscular 

 exertion employed. When Howlers are seen in the forest, there are 

 generally three or four of them mounted on the topmost branches of 

 a tree. It does not appear that their harrowing roar is emitted from 

 sudden alarm -, at least, it was not so in captive individuals. It is 

 probable, however, that the noise serves to intimidate their enemies." 



Another species of Howlers is the Preacher Monkey (Mycetes 

 Beelzebub}, an animal about the size of a fox, with long black glossy 

 hair, a round beard beneath the chin and throat, black glistening eyes,
