  Remarks. 
  — 
  Ateles 
  danensis 
  was 
  based 
  on 
  a 
  single 
  specimen 
  from 
  

   eastern 
  Panama, 
  exhibiting 
  characters 
  that 
  prove 
  to 
  be 
  inconstant 
  

   in 
  additional 
  specimens 
  examined, 
  and 
  the 
  name 
  must 
  be 
  relegated 
  to 
  

   the 
  synonymy 
  of 
  rohustus. 
  Despite 
  the 
  marked 
  contrast 
  in 
  color 
  be- 
  

   tween 
  this 
  black 
  form 
  and 
  the 
  red 
  monkey 
  of 
  eastern 
  Panama, 
  the 
  

   agreement 
  in 
  nearly 
  all 
  cranial 
  details 
  suggests 
  close 
  relationship. 
  

   The 
  auditory 
  bullae 
  are 
  usually 
  more 
  flattened 
  in 
  rohustus, 
  but 
  even 
  

   this 
  feature 
  is 
  not 
  always 
  distinctive. 
  To 
  the 
  southward, 
  on 
  the 
  other 
  

   hand, 
  close 
  alliance 
  with 
  fmciceps 
  is 
  indicated 
  by 
  the 
  slight 
  brownish 
  

   tinge 
  on 
  the 
  forehead 
  in 
  at 
  least 
  one 
  individual, 
  and 
  apparent 
  identity 
  

   in 
  cranial 
  details.

  to 
  

   two 
  specimens 
  collected 
  at 
  Tapalisa, 
  Panama. 
  

  

  It 
  is 
  therefore 
  evident 
  that 
  this 
  black 
  spider 
  monkey 
  ranges 
  from 
  

   the 
  Serrania 
  del 
  Darion 
  (Cerro 
  Pirre 
  and 
  Tapalisa) 
  southward 
  along 
  

   the 
  mountain 
  ranges 
  bordering 
  the 
  Rio 
  Sinii 
  in 
  Bolivar 
  to 
  the 
  moun- 
  

   tain 
  range 
  west 
  of 
  the 
  Rio
