  This 
  species, 
  from 
  the 
  island 
  in 
  the 
  southern 
  part 
  of 
  the 
  Natuna 
  

   Group, 
  is 
  very 
  dark 
  in 
  color, 
  differing 
  greatly 
  from 
  the 
  other 
  Macaques 
  

   from 
  the 
  rest 
  of 
  these 
  islands. 
  

  

  The 
  skull 
  resembles 
  more 
  nearly 
  that 
  of 
  P. 
  lingungensis 
  from 
  

   Lingung 
  Island, 
  near 
  to 
  Natuna, 
  but 
  the 
  length 
  of 
  the 
  tooth 
  row 
  is 
  much 
  

   less, 
  the 
  palate 
  is 
  wider, 
  and 
  the 
  braincase 
  broader. 
  One 
  example 
  

   only 
  was 
  obtained.
