two distinct species, without a suspicion, on the part of the author, as to 

 their identity. 



In 1833, Mr. Bennett, from a young specimen in the museum of the 

 Zoological Society, London, as already stated, characterized his Semno- 

 pithecus Nestor (in Proceedings of the Zoological Society, London) ; 

 observing, that " the moderate length of the hairs, the somewhat lighter 

 colour, and especially the white of the lower part of the sides of the face, 

 distinguish this species from the S. leucoprymnus." But neither to the 

 C. latibarbatus of Geoffrey, the " Purple-faced Monkey" of Pennant, nor 

 to the C. cephalopterus of Zimmermann, does he make any allusion. 



M. Desmoulins in the Diet. Classique d'Histoire Nat. describes a 

 species under the title of Semnopithecus fulvo-griseus, at the same 

 time assigning Java as its habitat; the species, however, is, un- 

 doubtedly, the S. latibarbatus, or leucoprymnus, or Nestor. Very 

 recently, the Author of this work carefully examined the specimen (a 

 young female, with the tail imperfect) of the S. latibarbatus in the 

 Museum of Paris, and which, as there is reason to believe, is the one 

 from which M. Desmoulins took his external characters. Underneath the 

 stand was written, "De M. Leschenault, 1822. Semnopitheque de Ceylon; 

 espece nouvelle. 11 n'y avait pas de crane dans la peau. C'est le C. leu- 

 coprymnus Otto (jeune) ; Semn. fulvo-griseus Desmoulins, Diet. Clas- 

 sique." It is also added, in reference to M. Desmoulins : " II parait qu'il 

 a pris un des squelettes du Cabinet d'Anatomie, appartenant au Croo 

 (Semn. comatus), pour le squelette de cette espece." 



The description of this specimen is as follows : Young female ; tail 

 imperfect ; the sides of the face are bearded ; the top of the head is of a 

 vinous grey-brown ; theg eneral colour is smoky brown ; the crupper is 

 of a dull grey, with a tinge of lake-colour ; the tail is of the same tint, 

 but a little darker ; the colour of the body deepens on the hands and feet 

 to black, with a tinge of brown ; the whiskers, beard, and throat are white. 

 Length, from the top of the head to the root of the tail, nineteen inches. 

 This description may be compared with that of the specimen, No. 16 a, in 

 the museum of the Zoological Society, London, and with the description 

 of C. latibarbatus in Desmarest's Mammalogie, p. 57, No. 16. 



It would appear that, as respects intensity of colour, the S. latibar- 

 batus is subject to some variation ; the colour of the adults being the 

 deepest : M. Temminck, indeed, describes it as black. The Author, 

 however, has seen no specimen in which the general hue of the body is 

 deeper than fuliginous, or deep blackish-grey, passing into black on the limbs. 



GENERAL HISTORY. The individual of the present species which 

 lived for some time in the menagerie of the Zoological Society, London, 

 resembled the Entellus in its general manners : it was extremely active, 

 and sometimes lively, playing with its companions in captivity ; it was
