236 PITHECUS 



31 ; length of upper molar series, 32; length of mandible, 97.1 ; length 

 of lower molar series, 40.1. Ex type United States National Museum. 



The specimen has a very worn coat, and hairs thinly dispersed on 

 limbs and under parts. While the coloring is dissimilar to that of P. 

 FASCicuLARis the great difference between it and the Trong Macaque 

 is in the size and shape of the skull and teeth. The skull of the 

 Sumatran animal, although of about the same age, is apparently one 

 third smaller. The Trong skull has a low crest from the midfrontal 

 to the occiput ; the rostrum is longer and broader ; zygomatic width 

 greater ; nasals wider ; bony palate deeper and longer ; teeth larger, 

 incisors more than twice as large ; mandible longer and heavier, the 

 ascending ramus broader and longer, with a very slight inclination 

 backward. 



A single specimen, a male, from Telibon Island has a smaller skull, 

 and the color of the animal is somewhat different. This example may 

 eventually prove distinct, but at present I leave it under the name of 

 the Trong Macaque.
