  The 
  types 
  of 
  F. 
  Cuvier's 
  species 
  are 
  not 
  now 
  in 
  the 
  Paris 
  Museum, 
  

   and 
  it 
  is 
  very 
  doubtful 
  if 
  any 
  number 
  of 
  them 
  ever 
  were 
  placed 
  in 
  

   the 
  collection. 
  They 
  were 
  menagerie 
  specimens 
  almost 
  without 
  excep- 
  

   tion, 
  and 
  without 
  any 
  certain 
  locality, 
  for 
  in 
  those 
  days 
  the 
  exact 
  

   habitat 
  of 
  any 
  animal 
  was 
  little 
  considered; 
  it 
  was 
  enough 
  if 
  the 
  con- 
  

   tinent 
  from 
  whence 
  an 
  example 
  came 
  was 
  known. 
  

  

  So 
  the 
  type 
  of 
  C. 
  chrysopus 
  is 
  not 
  extant 
  to-day, 
  but 
  there 
  are 
  

   several 
  specimens 
  in 
  the 
  Museum 
  and 
  the 
  above 
  description 
  was 
  

   taken 
  from 
  one 
  of 
  the 
  best 
  preserved, 
  although 
  doubtless 
  the 
  more 
  

   delicate 
  colors 
  of 
  the 
  pelage 
  have 
  faded 
  and 
  lost 
  much 
  of 
  their 
  depth 
  

   of 
  hue. 
  

  

  It 
  is 
  a 
  much 
  smaller 
  and 
  paler 
  colored 
  animal 
  than 
  C. 
  ALBIFRONS 
  

   and 
  belongs 
  to 
  the 
  group 
  of 
  this 
  genus 
  of 
  monkeys 
  with 
  the 
  front 
  half 
  

   of 
  the 
  head 
  white. 
  Two 
  of 
  the 
  Museum 
  specimens 
  came 
  from 
  Colom- 
  

   bia, 
  brought 
  by 
  M. 
  Plee 
  in 
  1826.
