   pi. 
  195, 
  1751, 
  as 
  sole 
  basis. 
  According 
  to 
  Edwards, 
  the 
  original 
  speci- 
  

   men 
  was 
  said 
  to 
  have 
  been 
  brought 
  from 
  "La 
  Vera 
  Cruz 
  in 
  New 
  Spain 
  

   [=]Vlexico]." 
  The 
  species 
  does 
  not 
  occur 
  naturally 
  outside 
  of 
  Colom- 
  

   bia. 
  The 
  true 
  habitat 
  of 
  the 
  species 
  was 
  first 
  determined 
  by 
  Hum- 
  

   boldt 
  {op. 
  cit. 
  supra). 
  The 
  data 
  given 
  by 
  Humboldt 
  plus 
  present 
  

   material 
  permit 
  restriction 
  of

  to 
  the

  southern 
  portion 
  of 
  department 
  of

  The 
  species

  occur

  Remarks. 
  — 
  There 
  is 
  no 
  evidence 
  that 
  the 
  range 
  of 
  Marikina 
  oedipus 
  

   overlaps 
  that 
  of 
  M. 
  leucopus 
  to 
  the 
  east 
  and 
  that 
  of 
  M. 
  geofroyi 
  to 
  

   the 
  west. 
  It 
  can 
  be 
  stated 
  categorically 
  that 
  oedipus 
  does 
  not 
  natur- 
  

   ally 
  occur 
  east 
  of 
  the 
  Rio 
  Magdalena 
  in 
  the 
  department 
  of 
  Magdalena. 
  

   It 
  is 
  possible, 
  however, 
  that 
  the 
  range 
  extends 
  west 
  as 
  far 
  as 
  the 
  Rio 
  

   Atrato 
  but 
  certainly 
  not 
  beyond. 
  No 
  marmosets 
  were 
  seen 
  by 
  the 
  

   writer 
  during 
  his 
  short 
  stay 
  in 
  the 
  Cienaga 
  de 
  Gu^jaro 
  region, 
  between 
  

   Barranquilla 
  and 
  Cartagena, 
  but 
  M. 
  oedipus 
  is 
  well 
  known 
  by 
  natives 
  

   there 
  and 
  is 
  said 
  to 
  be 
  common. 
  Humboldt 
  recorded 
  the 
  titi 
  from 
  

   Cartagena 
  and 
  the 
  canal 
  de 
  Mahates, 
  both 
  localities 
  a 
  short 
  distance 
  

   southwest 
  of 
  the 
  Cienaga 
  de 
  Guajaro.
