  The 
  general 
  appearance 
  of 
  this 
  monkey 
  is 
  that 
  of 
  a 
  reddish 
  brown 
  

   animal 
  with 
  yellowish 
  shoulders 
  and 
  upper 
  arms, 
  and 
  a 
  black 
  head 
  

   with 
  two 
  tufts 
  or 
  horns 
  upstanding, 
  one 
  on 
  each 
  side. 
  It 
  is, 
  however, 
  

   subject 
  to 
  great 
  variation, 
  to 
  such 
  an 
  extent 
  at 
  times, 
  that 
  it 
  would 
  

   seem 
  most 
  improbable 
  that 
  the 
  various 
  styles 
  should 
  represent 
  the 
  

   same 
  species. 
  It 
  is 
  practically 
  impossible 
  to 
  work 
  out 
  the 
  synonymy 
  

   of 
  this 
  variable 
  species 
  with 
  any 
  degree 
  of 
  accuracy, 
  since 
  the 
  name 
  

   fatuellus 
  has 
  been 
  given 
  to 
  various 
  Capuchins 
  from 
  numerous 
  locali- 
  

   ties 
  in 
  which 
  the 
  true 
  fatuellus 
  has 
  never 
  been 
  found. 
  It 
  has 
  been 
  

   attributed 
  to 
  the 
  Guianas, 
  but 
  the 
  writer 
  has 
  not 
  seen 
  an 
  authentic 
  

   specimen 
  from 
  that 
  part 
  of 
  South 
  America. 
  Wied, 
  (1. 
  c.) 
  calls 
  the 
  

   Capuchin 
  from 
  the 
  Province 
  of 
  Rio 
  de 
  Janeiro 
  this 
  species, 
  but 
  his 
  

   animal 
  is 
  the 
  C. 
  cirrifer 
  Geoff. 
  The 
  descriptions 
  of 
  the 
  earlier 
  Authors 
  

   are 
  often 
  so 
  brief 
  and 
  unsatisfactory 
  that 
  it 
  is 
  frequently 
  impossible 
  to 
  

   determine 
  what 
  species 
  it 
  is 
  to 
  which 
  they 
  refer, 
  and 
  there 
  is 
  so 
  much
