﻿PITHECUS

  The 
  skull 
  is 
  very 
  different 
  from 
  the 
  Bawean 
  Island 
  Macaque, 
  

   being 
  much 
  smaller, 
  with 
  a 
  narrow 
  rostrum, 
  decreasing 
  in 
  width 
  

   towards 
  incisors; 
  the 
  zygomatic 
  arch 
  has 
  very 
  little 
  expansion, 
  and 
  

   is 
  parallel 
  with 
  the 
  skull, 
  being 
  practically 
  straight 
  without 
  curve; 
  

   orbits 
  much 
  higher 
  than 
  wide 
  ; 
  a 
  low 
  ridge 
  is 
  present 
  from 
  frontal 
  to 
  

   occiput, 
  formed 
  of 
  the 
  inner 
  ridge-like 
  edge 
  of 
  orbits 
  uniting 
  on 
  anterior 
  

   part 
  of 
  the 
  frontal, 
  dividing 
  again 
  at 
  the 
  interparietal, 
  and 
  joining 
  the 
  

   occipital 
  ridge 
  on 
  either 
  side 
  ; 
  tooth 
  rows 
  straight, 
  palate 
  narrow 
  ; 
  upper 
  

   incisors 
  projecting.

  This 
  Macaque 
  is

  but 
  differs 
  in 
  its 
  general 
  

   paler 
  coloration, 
  lighter 
  hands, 
  feet, 
  and 
  tail. 
  Four 
  examples

   procured 
  at
