temples, sides of the head and neck, and chin. This white is continued down the 

 throat and chest to the under surface of the body, and the inner sides of the upper 

 parts of the limbs. 



This exceedingly handsome species differs from all the langurs yet mentioned, 

 in the marked contrast presented by its black crest to the brilliant white of the 

 temples and cheeks. A specimen was obtained by Mr. John Whitehead on Kina 

 Balu, the great mountain of Borneo, at an elevation of some four thousand feet 

 above the level of the sea ; and this explorer states that the species is fairly common 

 in certain patches of forest on the mountain and in its neighborhood. 



The reader might well be excused for thinking that with this he had reached 

 the end of the already long list of langurs ; but there are several other species more 

 or less closely related to those we have mentioned. As, however, even the 

 enumeration of these might be wearisome, we pass on to the consideration of 



THE Douc (Semnopithec2is nemtzus) 



The douc, or variegated langur, is an inhabitant of the forests of Cochin-China, 

 where it is found near the coast, as well as in the interior, and is remarkable for its 

 brilliant coloration. There seems to be great doubt as to the origin of the name 

 Douc, which was applied to this monkey by Buffon, and it is stated to be unknown 



in Cochin-China ; it has, however, 

 been so long in use that there would 

 be no advantage gained by chang- 

 ing it. 



The general form of the douc 

 is so different from that of other 

 langurs, that the late Dr. Gray pro- 

 posed to make it the type of a dis- 

 tinct genus. Thus the general build 

 is more robust, and the limbs are 

 stouter, and of nearly equal lengths ; 

 whereas in the typical langurs the 

 arms are considerably shorter than 

 the legs. 



The hair on the top of the head 

 is directed backwards, without any 

 crest, and the brilliant white whisk- 

 ers have likewise the same direction, and are closely pressed to the face. The 

 general color of the head is brown, but there is a narrow band of bright chestnut 

 passing backwards under the ears, and the naked face is of a brilliant yellow, 

 which makes a bold contrast to the pure white whiskers. Owing to the hairs of 

 the body having alternate dark and light rings of color, the general tint of the 

 body is a mottled, grizzled gray, darker on the upper than on the under parts. The 

 upper parts of the arms and legs, as well as the hands and feet, are of a deep black ; 

 but the lower legs are of a full chestnut, and the fore-arms white. A large patch
