On the Plate which illustrates the present article, an animal is represented 

 which agrees with the Semnopithecus maurus in aU points excepting the external 

 covering. The permanency with which this exists, and the pecuhar 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 this 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 this 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 aU 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
