﻿CYNOPITHECUS 
  163 
  

  

  regarded 
  in 
  any 
  way 
  as 
  a 
  specific 
  character. 
  A 
  series 
  of 
  this 
  species 
  

   in 
  the 
  Leyden 
  Museum 
  from 
  Lembeh 
  and 
  Minahassa, 
  show 
  that 
  the 
  

   young 
  are 
  brown 
  on 
  the 
  back 
  and 
  shoulders 
  varying 
  in 
  depth 
  among 
  

   individuals 
  ; 
  belly, 
  usually 
  black. 
  

  

  There 
  are 
  four 
  examples 
  in 
  the 
  Leyden 
  Museum 
  which, 
  according 
  

   to 
  Schlegel, 
  served 
  as 
  types 
  for 
  Temminck's 
  species. 
  P. 
  nigrescens, 
  

   three, 
  Nos. 
  6, 
  8, 
  and 
  9 
  from 
  Gorontalo, 
  and 
  No. 
  7, 
  from 
  Toulabello. 
  

   Of 
  these 
  only 
  No. 
  6 
  can 
  be 
  a 
  type, 
  as 
  the 
  others 
  were 
  only 
  collected 
  in 
  

   1864 
  by 
  Rosenberg 
  ; 
  and 
  lastly 
  No. 
  10, 
  not 
  mentioned 
  by 
  Schlegel 
  as 
  a 
  

   type. 
  They 
  are 
  all 
  immature, 
  No. 
  9 
  being 
  quite 
  a 
  baby, 
  the 
  other 
  

   three 
  about 
  three 
  quarters 
  grown. 
  As 
  is 
  to 
  be 
  expected 
  none 
  of 
  them 
  

   are 
  black 
  as 
  the 
  adult 
  would 
  be, 
  but 
  exhibit 
  the 
  brown 
  coloring 
  char- 
  

   acteristic 
  of 
  young 
  animals 
  of 
  C. 
  niger, 
  with 
  the 
  limbs, 
  hands, 
  feet 
  

   and 
  top 
  of 
  head 
  black. 
  I 
  can 
  perceive 
  no 
  characters 
  to 
  distinguish 
  

   these 
  examples 
  from 
  those 
  of 
  C. 
  niger 
  of 
  a 
  similar 
  age, 
  and 
  agree 
  with 
  

   Schlegel, 
  that 
  they 
  cannot 
  be 
  separated 
  from 
  that 
  species.

  The 
  skull 
  is 
  a 
  true 
  Cynopithe- 
  

   cus 
  but 
  not 
  so 
  broad 
  on 
  the 
  rostrum 
  comparatively 
  as 
  that 
  of 
  C. 
  niger, 
  

   but 
  it 
  is 
  more 
  typical 
  than 
  many 
  of 
  the 
  others. 
  

  

  The 
  type 
  is 
  a 
  young 
  animal 
  and 
  there 
  are 
  indications 
  on 
  both 
  arms 
  

   and 
  legs 
  of 
  a 
  change 
  from 
  brown 
  to 
  the 
  black 
  of 
  the 
  adult 
  ; 
  thus, 
  the 
  

   black 
  on 
  the 
  thighs 
  has 
  extended 
  from 
  the 
  hips 
  nearly 
  half 
  way 
  to 
  the 
  

   knees 
  ; 
  and 
  on 
  the 
  feet, 
  and 
  especially 
  on 
  the 
  inner 
  side 
  of 
  the 
  leg, 
  the 
  

   black 
  is 
  beginning 
  to 
  appear. 
  

  

  The 
  description 
  of 
  C. 
  hypomelas 
  is 
  as 
  follows 
  : 
  

  

  Color. 
  Head 
  crested, 
  with 
  upper 
  part 
  of 
  back 
  reddish 
  brown 
  

   almost 
  black 
  ; 
  back 
  and 
  outer 
  side 
  of 
  limbs,

  tinged 
  with 
  brown 
  ;

  Prout's 
  brown 
  ;
