  While 
  resembling 
  the 
  typical 
  C. 
  capucinus 
  (Linn.), 
  in 
  general 
  

   appearance 
  this 
  species 
  differs 
  in 
  the 
  color 
  of 
  the 
  forehead 
  which 
  is 
  

   bistre, 
  and 
  not 
  white 
  nor 
  yellowish 
  white, 
  and 
  also 
  in 
  the 
  black 
  chest, 
  

   the 
  white 
  of 
  the 
  throat 
  not 
  extending 
  downward. 
  The 
  skull 
  also 
  differs, 
  

   in 
  having 
  a 
  longer 
  braincase, 
  and 
  is 
  not 
  wide 
  over 
  root 
  of 
  zygoma 
  as 
  

   is 
  the 
  skull 
  of 
  C. 
  capucinus 
  (Linn.). 
  The 
  orbits 
  are 
  smaller, 
  the 
  

   nasals 
  narrower 
  and 
  the 
  teeth 
  of 
  the 
  upper 
  molar 
  series 
  much 
  shorter, 
  

   the 
  last 
  molar 
  being 
  about 
  half 
  the 
  size 
  of 
  m 
  1 
  and 
  appearing 
  minute 
  

   when 
  compared 
  with 
  the 
  other 
  molars. 
  

  

  The 
  Collector, 
  the 
  late 
  J. 
  H. 
  Batty, 
  stated 
  that 
  this 
  monkey 
  was 
  

   not 
  found 
  in 
  low 
  lands, 
  but 
  is 
  a 
  mountain 
  species, 
  a 
  sagacious 
  and 
  shy 
  

   animal, 
  and 
  an 
  expert 
  jumper.
