less high ; the occipital region being prolonged less backwards, and the lambdoidal 

 suture is thrown upwards. The face is short, and the nasal portion is narrow 

 and depressed, wanting the interorbital swelling that occurs in so many of the 

 crested fSemnopitheci. The orbits are rather large. 



The proportions of the limbs in these two species have been stated by 

 A. M. -Edwards as follows : taking for the two as a unit of measure the total length 

 of the vertebral column comprised between the head and the end of the sacrum : 







S. nigripes.

Inhabits Saigon and the forests bordering the Mekong towards its mouth. 



This species, from what has been stated, is evidently closely allied to S. nemaeus, 

 which is a parallel species inhabiting the more northerly portion of Cochin China, 

 the first being recognised by its black hinder extremities and the latter by the 

 lower half of the hind limbs being reddish-brown or red.
