  There 
  is 
  a 
  great 
  difference 
  in 
  the 
  coloring 
  of 
  the 
  sexes, 
  the 
  female 
  

   being 
  much 
  lighter 
  and 
  redder, 
  and 
  this 
  difference 
  is 
  exhibited 
  in 
  very 
  

   young 
  males 
  which 
  are 
  as 
  dark 
  as 
  the 
  adult 
  males 
  ; 
  a 
  coloration 
  quite 
  

   dissimilar 
  from 
  that 
  of 
  the 
  females. 
  This 
  species 
  appears 
  to 
  be 
  also 
  an 
  

   inhabitant 
  of 
  the 
  neighboring 
  island 
  of 
  Batam. 
  There 
  are 
  only 
  females 
  

   unfortunately 
  from 
  that 
  island 
  in 
  the 
  collection, 
  and 
  they 
  closely 
  

   resemble 
  in 
  color 
  examples 
  of 
  the 
  same 
  sex 
  from 
  Batam. 
  Of 
  course, 
  

   when 
  adult 
  males 
  are 
  procured 
  cranial 
  characters 
  and 
  difference 
  of 
  

   coloring 
  may 
  be 
  discovered, 
  but 
  with 
  the 
  present 
  material 
  only 
  avail- 
  

   able, 
  the 
  examples 
  from 
  the 
  two 
  islands 
  must 
  be 
  regarded 
  as 
  belonging 
  

   to 
  the 
  same 
  species. 
  This 
  is 
  a 
  very 
  dark 
  and 
  handsome 
  Macaque, 
  

   closely 
  allied 
  in 
  general 
  appearance 
  to 
  the 
  species 
  from 
  Singapore 
  

   Island, 
  although 
  there 
  are 
  some 
  differences 
  in 
  color 
  on 
  the 
  crown 
  of 
  the 
  

   head 
  and 
  on 
  the 
  legs. 
  But 
  the 
  skulls 
  are 
  not 
  alike 
  and 
  the 
  size 
  of 
  the 
  

   teeth 
  differs, 
  especially 
  the 
  upper 
  incisors 
  which 
  are 
  much 
  smaller 
  in 
  P. 
  

   bintangensis, 
  and 
  in 
  the 
  straight 
  tooth 
  rows. 
  The 
  other 
  cranial 
  

   differences 
  are 
  mentioned 
  above. 
  Specimens 
  were 
  obtained 
  on 
  the 
  

   northern 
  coast 
  of 
  Bintang 
  Island 
  at 
  Sanjang, 
  Tanjang 
  Sau, 
  Tomback, 
  

   Pasir 
  Panjang, 
  and 
  Sungei 
  Boru 
  whence 
  the 
  type 
  specimen 
  came.
