SEMNOPITHECUS PYRRHUS, 
distant parts of the globe. In exhibiting our animal with a peculiar name, and 
thus proposing an addition to the Systematic Catalogue, I shall not oppose my judg- 
ment to those Naturalists who, after instituting a careful comparison, may be dis- 
posed to consider it merely as a variety of the Semnopithecus maurus. 
Our animal agrees strictly with the Semnopithecus maurus, as described in the 
Fourth Number of this Work, in all points that regard generic character. A remark- 
able attribute of this is a great length of body and slenderness of the extremities ; 
the figure of the Semnopithecus Pyrrhus exhibits these peculiarities of form, which 
are concealed in the attitude of the S. maurus. The lighter tints of the breast and 
abdomen are also rendered conspicuous in our present figure. 
The hairy covering of the Semnopithecus Pyrrhus has the same character as in 
the S. maurus ; it is long, delicate, soft, and silky. Its colour, in the latter, is 
intensely black ; in the former, it is reddish-brown, with a beautiful golden gloss on 
the back, head, tail, and the extremities, varying slightly in its degree of intensity 
as it approaches the sides and forehead : underneath and along the interior of 
the extremities it is pale yellowish, with a golden lustre. The long, shaggy, 
thickly disposed fur which covers the upper parts, is separated by a regular boundary 
stretching along the hypochondria?, from the hair on the abdomen, which is very 
thinly disposed, curled, silky, and of a very delicate texture. 
Our animal greatly resembles, in its external covering, the Cercopithecus aura- 
tus, described by M. Geofrroy St. Hilaire in Vol. XIX. of the Ann. du Mus., from 
a specimen in the collection of M. Temminck ; but the latter has a clear distinguish- 
ing character in the black mark above the rotula ; and, as far as appears from the 
description, is of a more robust habit, and does not belong to the genus Semno- 
pithecus, as defined by M. Fred. Cuvier. 
Our animal, when full grown, is equal in size to the Semnopithecus maurus.
