  of 
  versicolor 
  by 
  paler 
  hands 
  and 
  wrists. 
  Identity 
  with 
  typical 
  versicolor 
  

   IS 
  shown, 
  however, 
  by 
  coloration 
  of 
  ventral 
  sm-face, 
  sharp 
  contrast 
  

   between 
  median 
  dorsal 
  region 
  and 
  reddish 
  limbs, 
  and 
  by 
  the 
  pale 
  

   tail.

  Remarks. 
  — 
  Santa 
  Fe 
  de 
  Bogotd, 
  where 
  versicolor 
  was 
  said 
  to 
  have 
  

   originated, 
  is 
  also 
  the 
  ancient 
  name 
  of 
  a 
  large 
  area 
  comprising 
  the 
  

   present 
  department 
  of 
  Cundinamarca 
  and 
  parts 
  of 
  neighboring 
  

   departments, 
  including 
  the 
  upper 
  Rio 
  Meta 
  region. 
  The 
  above 
  

   described 
  male 
  from 
  Rio 
  ChiK, 
  Tolima, 
  agrees 
  best 
  with 
  the 
  type. 
  

   Nevertheless, 
  it 
  would 
  be 
  premature 
  to 
  regard 
  it 
  as 
  certainly 
  typical. 
  

   The 
  nature 
  of 
  material 
  here 
  assigned 
  to 
  versicolor 
  indicates, 
  neverthe- 
  

   less, 
  that 
  the 
  type 
  specimen 
  did 
  originate 
  somewhere 
  in 
  the 
  middle 
  

   Rio 
  Magdalena 
  Valley 
  exclusive 
  of 
  the 
  western 
  slope 
  of 
  the 
  Cordillera 
  

   Oriental 
  north 
  of 
  Bogota. 
  

  

  Nape 
  and 
  upper 
  surface 
  of 
  hands 
  and 
  feet 
  of 
  type 
  are 
  dark 
  brown, 
  

   not 
  black 
  as 
  originally 
  described.
