 Semnopithecus barbei, Anderson, An. Zool. Res. p. 12 ; id. Cat. p. 48. 



No crest. Hair on the crown not radiating. Whiskers long. 

 Beard short. Hair on the vertex slightly lengthened, but not so 

 distinctly as in 8. obscurus. 



Colour. Blackish brown to black above and below, with a silvery 

 greyish wash on the upper parts and outside of limbs. Eyebrows 

 and whiskers black. Naked face bluish black. 



Dimensions. Head and body 19'5 inches, tail 29. 



Distribution. The types were from the interior of the Tipperah 

 hills. This species has also been obtained by Anderson on the 

 Irawadi just above Mandalay in Upper Burma, and further north 

 in the Kakhyen Hills, and by Mr. Ossian Limborg on Muleyit 

 mountain west of Moulmain in Tenasserim. Mr. Limborg's spe- 

 cimens have been identified by Dr. Anderson, but require com- 

 parison with the monkey from the same neighbourhood identified 

 as S. phayrei by Colonel Tickell. 



Habits. Similar to those of other members of the genus. 

 Anderson observed this monkey in parties of from thirty to fifty. 

 They were not shy. 



It is possible that this species, of which I have not been able to 

 examine specimens, is only a variety of S. obscurus. This was 

 Blyth's view at one time (J. A. S. B. xxiv, p. 711), and Anderson 

 (1. c.} has shown that there is much similarity in the skulls of these 

 two forms. Both have rounded orbits and a comparatively elon- 

 gate interorbital region. Blyth, in his Catalogue and in his list 

 of Burmese Mammals, however, classed jS>. barbei as closely allied 

 to S. femoralis, if not identical. This scarcely appears to me 

 borne out by the description.

A somewhat peaked, longitudinal median crest on the vertex. 

 Hair of crown elongated, directed backwards, not radiating. 

 Whiskers long, partly covering the ears. In the skull the supra- 

 orbital ridges are but little developed, and the orbits are less
