This is a much paler Macaque than any of the island forms 

 described, with pale yellowish gray arms, and whitish gray legs. The 

 general color of the top of head and nape at a little distance is 

 ochraceous, contrasting rather strongly with the reddish wood brown 

 of the back. The skull is rather large and heavy, more like that of P. 

 FASCiciJLARis of Sumatra, than any of those described from the various 

 islands. Two specimens from Tioman Island, north of Tingi, are 

 much darker in color, but as they present no cranial differences from 

 Tingi Island examples, I have not separated them, though the coloring 

 is quite different.
