APES AND MONKEYS. 
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 neighbourhood. 
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 (Semnopitkecus nemceus ). 
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 
distinct 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, with¬ 
out any crest; and the brilliant 
white whiskers have likewise the same direction, and are closely pressed to 
the face. The general colour 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 colour, the general tint of the body is a mottled, grizzled grey, 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 on the rump near the root of 
the tail, as well as the tail itself, are likewise white. All these colours are 
extremely brilliant, and sharply defined, without any tendency to blend with one 
another at their junctions, so that this monkey is one of the most gorgeously 
coloured Mammals known. 
We have very little information as to the habits of the douc in a state of 
nature, and it does not appear that it has been exhibited alive (at least of late 
years) in this country. M. Rey, a French captain, who visited Cochin-China in the
