﻿CYNOPITHECUS

  Cynopithecus, 
  to 
  follow 
  him 
  in 
  this 
  part 
  of 
  his 
  paper 
  would 
  

   take 
  us 
  too 
  far 
  afield, 
  and 
  we 
  will 
  consider 
  his 
  review 
  only 
  as 
  it 
  

   relates 
  to 
  the 
  black 
  monkeys 
  of 
  Celebes. 
  He 
  recognizes 
  the 
  

   following 
  species 
  : 
  C. 
  Niger 
  Desm., 
  C. 
  nigrescens 
  Temm. 
  = 
  C. 
  

   Niger, 
  with 
  a 
  comparison 
  of 
  their 
  skulls 
  ; 
  C. 
  tonkeanus 
  Meyer 
  ; 
  

   P. 
  inornatus 
  Gray, 
  = 
  C. 
  maurus 
  (F. 
  Cuv.), 
  juv. 
  ; 
  C. 
  ochreatus 
  

   Ogilby, 
  and 
  C. 
  maurus 
  (F. 
  Cuv.). 
  He 
  describes 
  as 
  distinct 
  

   from 
  these 
  P. 
  hecki, 
  probably 
  from 
  Buol, 
  in 
  the 
  northwestern 
  

   peninsula, 
  the 
  locality 
  from 
  which 
  P. 
  nigrescens 
  Temm., 
  was 
  

   described, 
  and 
  hecki 
  is 
  the 
  same 
  as 
  that 
  form 
  ; 
  P. 
  tonsus 
  from 
  

   an 
  immature 
  animal 
  and 
  no 
  locality, 
  which 
  = 
  C. 
  tonkeanus 
  

   from 
  the 
  eastern 
  or 
  middle 
  peninsula; 
  P. 
  hypomelas 
  no 
  locality 
  

   given, 
  but 
  which 
  he 
  says 
  is 
  not 
  quite 
  adult 
  and 
  stands 
  between 
  

   his 
  tonsus 
  and 
  inornatus, 
  and 
  its 
  skull 
  is 
  similar 
  to 
  that 
  of 
  the 
  

   last 
  named, 
  inornatus, 
  and 
  with 
  that 
  form 
  also, 
  both 
  = 
  C. 
  

   maurus 
  (F. 
  Cuv.) 
  ; 
  and 
  lastly, 
  P. 
  brunescens 
  from 
  the 
  south 
  

   easterly 
  peninsula, 
  and 
  Island 
  of 
  Buton. 
  The 
  type 
  of 
  this 
  

   last 
  named 
  is 
  a 
  very 
  young 
  animal, 
  too 
  young 
  to 
  exhibit 
  any 
  

   distinctive 
  characters, 
  and 
  probably 
  is 
  the 
  same 
  as 
  C. 
  

   ochreatus 
  which 
  inhabits 
  the 
  same 
  peninsula. 
  In 
  order 
  to 
  

   localize 
  the 
  species 
  described, 
  the 
  various 
  peninsulas 
  have 
  been 
  

   divided 
  into 
  northern, 
  southern, 
  eastern 
  and 
  western 
  portions, 
  

   without 
  any 
  definite 
  information 
  that 
  the 
  forms 
  indicated 
  are 
  

   thus 
  restricted. 
  

  

  GEOGRAPHICAL 
  DISTRIBUTION 
  OF 
  THE 
  SPECIES. 
  

  

  It 
  must 
  be 
  confessed 
  that 
  with 
  only 
  our 
  present 
  inadequate 
  

   knowledge 
  of 
  the 
  species 
  of 
  the 
  genera 
  Cynopithecus 
  and 
  Magus, 
  

   their 
  distribution 
  in 
  the 
  Island 
  of 
  Celebes 
  is 
  mostly 
  guesswork. 
  

   Matschie's 
  dispersal 
  of 
  the 
  species 
  he 
  recognizes 
  is, 
  at 
  least 
  in 
  part, 
  

   purely 
  imaginary, 
  and 
  he 
  has 
  no 
  positive 
  information 
  that 
  any 
  of 
  the 
  

   species 
  were 
  restricted 
  within 
  the 
  boundaries 
  he 
  gave 
  them. 
  We 
  think 
  

   we 
  know 
  that 
  certain 
  species 
  come 
  from 
  certain 
  parts 
  of 
  the 
  island, 
  but 
  

   what 
  may 
  be 
  their 
  boundaries, 
  or 
  whether 
  they 
  have 
  any 
  at 
  all, 
  we 
  have 
  

   no 
  certain 
  knowledge. 
  The 
  following 
  is 
  supposed 
  to 
  be 
  the 
  dispersion 
  

   of 
  the 
  species 
  recognized 
  in 
  this 
  work 
  : 
  In 
  the 
  northern 
  peninsula 
  from 
  

   Minahassa 
  on 
  the 
  east 
  to 
  Tomini 
  on 
  the 
  west, 
  and 
  down 
  the 
  west 
  coast 
  

   to 
  Balanipa, 
  and 
  also 
  on 
  the 
  small 
  mountainous 
  Island 
  of 
  Menado-toua 
  

   off 
  the 
  northeastern 
  extremity 
  of 
  Celebes, 
  and 
  the 
  Island 
  of 
  Batchian. 
  

   C. 
  niger 
  is 
  found.
