ON the Plate which illustrates the present article, an animal is represented 
which agrees with the Semnopithecus maurus in all points excepting the external 
covering. The permanency with which this exists, and the peculiar name of our 
animal among the natives of Java, must be taken into consideration, in determining its 
title to a specific distinction. The colour extending over the upper parts of tins ani- 
mal, and over the exterior of the limbs, is essentially different from the fulvous tint 
observed in the Semnopithecus maurus, before the change of colour to black takes 
place, which, commencing on the extremities, spreads gradually over the whole 
animal. No discoloration of tins kind occurs in the Semnopithecus Pyrrhus. 
Various young individuals, contained in the Honourable Company's Museum, 
exhibit, in a striking manner, the changes which occur in the covering of the 
Semnopithecus maurus, as it gradually increases to maturity. Three adult speci- 
mens of the Semnopithecus Pyrrhus agree in all points, as far as regards their 
colour. I am sensible of the difficulty which frequently occurs in distinguishing 
animals specifically : and if doubts still remain regarding the specific distinctions of 
quadrupeds which are natives of Europe, the same may be expected in animals from
