  that 
  they 
  can 
  be 
  referred 
  to 
  any 
  known 
  species, 
  and 
  must 
  be 
  recognized 
  

   as 
  distinct. 
  It 
  is 
  a 
  plain 
  light 
  brown 
  animal, 
  with 
  dark 
  head, 
  limbs, 
  

   and 
  tail, 
  and 
  whitish 
  under 
  parts. 
  

  

  The 
  specimen 
  marked 
  on 
  ticket, 
  'type' 
  was 
  presented 
  by 
  M. 
  Plee 
  

   and 
  said 
  to 
  have 
  come 
  from 
  Colombia. 
  It 
  is 
  much 
  faded, 
  mummy 
  

   brown 
  on 
  head, 
  arms, 
  and 
  shoulders, 
  with 
  a 
  white 
  spot 
  in 
  the 
  center 
  

   of 
  the 
  forehead; 
  forearms, 
  upper 
  parts 
  of 
  body, 
  flanks, 
  legs 
  and 
  tail 
  

   yellowish 
  brown 
  ; 
  hands 
  and 
  feet 
  blackish 
  brown. 
  

  

  Measurements. 
  Total 
  length, 
  1,346.40; 
  tail, 
  163.85; 
  foot, 
  177.80. 
  

  

  Another 
  specimen, 
  better 
  in 
  color, 
  has 
  the 
  head, 
  shoulders, 
  arms, 
  

   hands, 
  feet 
  and 
  tail 
  blackish 
  brown, 
  darker 
  than 
  seal 
  brown; 
  white 
  

   triangular 
  spot 
  on 
  forehead; 
  upper 
  part 
  of 
  body 
  and 
  flanks 
  Prout's 
  

   brown 
  ; 
  legs 
  Prout's 
  brown 
  nearly 
  on 
  front 
  edge 
  over 
  knee 
  ; 
  inner 
  side 
  

   of 
  limbs 
  and 
  under 
  parts 
  of 
  body, 
  grayish 
  white; 
  tail 
  above, 
  blackish 
  

   brown 
  like 
  arms, 
  beneath, 
  yellowish. 
  

  

  Exposure 
  to 
  light 
  has 
  changed 
  this 
  specimen 
  somewhat, 
  as 
  one 
  of 
  

   the 
  legs 
  is 
  paler 
  than 
  the 
  other, 
  and 
  possibly 
  the 
  back 
  and 
  sides 
  may 
  

   have 
  changed 
  also, 
  but 
  the 
  head, 
  arms, 
  hands, 
  feet 
  and 
  tail 
  doubtless 
  

   still 
  retain 
  the 
  original 
  color. 
  As 
  the 
  description 
  shows, 
  it 
  is 
  a 
  very 
  

   much 
  darker 
  animal 
  than 
  the 
  one 
  marked 
  as 
  the 
  'type,' 
  and 
  it 
  does 
  not 
  

   seem 
  likely 
  that 
  the 
  latter 
  ever 
  was 
  as 
  dark, 
  which 
  gives 
  rise 
  to 
  the 
  

   suspicion 
  that 
  there 
  may 
  be 
  a 
  considerable 
  variation 
  in 
  color 
  among 
  

   members 
  of 
  this 
  form. 
  All 
  the 
  specimens 
  have 
  a 
  triangular 
  white 
  spot 
  

   on 
  the 
  forehead, 
  the 
  lower 
  points 
  reaching, 
  as 
  stated 
  by 
  Geoffroy, 
  to 
  the 
  

   corners 
  of 
  the 
  eyes. 
  If 
  this 
  is 
  a 
  hybrid, 
  as 
  its 
  name 
  would 
  seem 
  to 
  

   imply, 
  it 
  is 
  extremely 
  difficult 
  to 
  determine 
  what 
  species 
  have 
  pro- 
  

   duced 
  it.
