484 QUADRUMANA. 



the back, the crupper, and the tail are of a pale grey, with a tinge of lake- 

 brown ; the end of the tail, which is somewhat tufted, becoming almost 

 white ; a large pointed or triangular beard, of soft, long, whitish hairs, 

 occupies the sides of the face ; the top of the head and the back of the 

 neck are of a greyish brown ; the under parts are paler than the back, 

 being of a dusky grey ; a ridge of stiff black hairs, as in the Semnopitheci 

 generally, runs over the eyes ; the palms and soles are of a dull black, 

 as is also the skin of the face, with a tinge of purple.

The above details are taken'from a specimen (16 a, in Catalogue, 1838) 

 in the museum of the Zoological Society, London, and which died in the 

 menagerie. A smaller specimen (16, idem) is the original of Mr. 

 Bennett's Semnopithecus Nestor, in Proceedings of the Zoological Society, 

 London, 1833, p. 67. 



The present species was first described by Pennant, in his Synopsis 

 (p. 109, tab. xiv. fig. 1771), under the name of the Lion-tailed Monkey; 

 and it is on this figure and description, that Zimmermann (Geogr. Gesch. 

 ii. 1780) founded his Cercopithecus cephalopterus. Subsequently, from 

 a drawing communicated to him by Mr. Loten, Pennant, in his History of 

 Quadrupeds (vol. i. p. 189, tab. 21, 1793), figured and re-described it as the 

 Purple-faced Monkey ; and from this authority Buffon derives the delinea- 

 tion and account of the Guenon a face pourpre, in the Supplement to his 

 great work (vol. vii.). In Pennant's Quadrupeds, the face and hands 

 of this Monkey are stated to be purple ; but, most probably, these parts 

 were too highly coloured in the drawing mentioned ; for, in a young 

 example living in the menagerie of the Zoological Society, London, 1838-9, 

 the purple tint on the face was very slight ; and in specimens preserved in 

 the museum, it is not to be discerned. In the Annales du Musee, 1812 

 (vol. xix.), M. Geoffroy St. Hilaire characterized the Purple-faced 

 Monkey under the title of Cercopithecus latibarbatus, in allusion to the 

 long, wing-like whiskers of white hairs, which garnish the sides of the 

 face; whence also the title, cephalopterus, proposed, long before, by 

 Zimmermann. 



The next original description of this Monkey is by Otto (in the 

 Nova Acta Acad. Nat. Curios, xii. 1825), under the title of Cerco- 

 pithecus leucoprymnus, that naturalist failing to recognise in his specimen 

 the characters either of C. latibarbatus, as detailed by Geoffrey, or of 

 C. cephalopterus, as drawn by Zimmermann, from Pennant's Lion-tailed 

 Monkey, var. /3. In Lesson's Manuel, while no notice is taken of C. 

 cephalopterus, the C. latibarbatus and the C. leucoprymnus are given as
