  This 
  species 
  has 
  for 
  a 
  long 
  time 
  been 
  regarded 
  by 
  most 
  writers 
  

   as 
  the 
  same 
  as 
  P. 
  irus 
  (F. 
  Cuv.), 
  but 
  that 
  species 
  has 
  black 
  hands 
  and 
  

   feet 
  as 
  was 
  originally 
  described 
  by 
  F. 
  Cuvier, 
  whereas 
  the 
  present 
  

   species 
  has 
  gray 
  hands 
  and 
  feet, 
  and 
  the 
  general 
  color 
  of 
  the 
  pelage 
  

   is 
  tawny, 
  quite 
  a 
  different 
  hue 
  from 
  that 
  of 
  P. 
  irus. 
  The 
  Macaques 
  

   on 
  the 
  islands 
  lying 
  between 
  Sumatra 
  and 
  Singapore 
  have 
  a 
  pelage 
  

   whose 
  color 
  is 
  very 
  similar 
  to 
  this 
  one 
  from 
  Sumatra, 
  but 
  possess 
  

   dental 
  and 
  cranial 
  characters 
  sufficiently 
  different 
  to 
  prevent 
  them 
  

   from 
  being 
  considered 
  the 
  same 
  species. 
  Raffles 
  in 
  his 
  description, 
  

   (1. 
  c.) 
  made 
  no 
  mention 
  of 
  the 
  color 
  of 
  the 
  hands 
  and 
  feet, 
  and 
  this 
  

   important 
  character 
  for 
  differentiating 
  this 
  from 
  the 
  Malay 
  Macaque 
  

   seems 
  to 
  have 
  been 
  entirely 
  overlooked 
  by 
  subsequent 
  Authors. 
  In 
  

   size 
  P. 
  fascicularis 
  and 
  P. 
  irus 
  are 
  about 
  equal, 
  but 
  in 
  general 
  

   appearance 
  they 
  do 
  not 
  resemble 
  each 
  other 
  very 
  much.
