  This 
  Macaque 
  exhibits 
  an 
  entirely 
  differently 
  colored 
  pelage 
  from 
  

   the 
  Singapore 
  species, 
  and 
  one 
  much 
  nearer 
  to 
  the 
  Karimon 
  and 
  

   Sumatra 
  forms, 
  while 
  the 
  skull 
  is 
  nearer 
  in 
  its 
  characters 
  to 
  the 
  Singa- 
  

   pore 
  Macaque 
  than 
  to 
  those 
  species 
  living 
  on 
  the 
  neighboring 
  islands. 
  

   It 
  is 
  a 
  reddish 
  brown 
  animal, 
  duller 
  in 
  hue 
  than 
  either 
  the 
  Karimon 
  

   or 
  Sumatra 
  Macaques. 
  The 
  affinities 
  of 
  the 
  monkeys 
  from 
  these 
  

   various 
  islands 
  is 
  rather 
  difficult 
  to 
  understand, 
  and 
  why 
  their 
  coloring 
  

   should 
  be 
  similar 
  in 
  Koendoer 
  and 
  the 
  islands 
  to 
  the 
  south 
  as 
  far 
  as 
  

   Sumatra, 
  and 
  the 
  cranial 
  characters 
  should 
  be 
  nearly 
  alike 
  with 
  the 
  

   Singapore 
  species, 
  separated 
  as 
  it 
  is 
  by 
  intervening 
  islands, 
  inhabited 
  

   by 
  an 
  allied 
  but 
  different 
  form. 
  It 
  would 
  be 
  practically 
  useless 
  to 
  

   theorize 
  upon 
  this 
  condition 
  of 
  things 
  ; 
  but 
  the 
  animals 
  are 
  probably 
  in 
  

   a 
  process 
  of 
  change 
  influenced 
  by 
  their 
  insular 
  habitats, 
  though 
  as 
  these 
  

   islands 
  are 
  but 
  short 
  distances 
  apart, 
  it 
  is 
  difficult 
  to 
  appreciate 
  how 
  

   great 
  such 
  influences 
  may 
  be. 
  At 
  present 
  we 
  only 
  know 
  that 
  differ- 
  

   ences 
  do 
  exist 
  of 
  such 
  importance 
  as 
  to 
  compel 
  us 
  to 
  regard 
  the 
  

   individuals 
  from 
  various 
  islands 
  as 
  possessing 
  characters 
  so 
  unrecon- 
  

   cilable 
  as 
  to 
  prevent 
  us 
  from 
  considering 
  them 
  all 
  as 
  belonging 
  to 
  one 
  

   species.
