  By 
  Philip

  Monkeys 
  collected 
  in 
  northern 
  Colombia 
  by 
  the 
  author 
  during 
  his 
  

   tenure 
  of 
  the 
  Walter 
  Rathbone 
  Bacon 
  Traveling 
  Scholarship 
  number 
  

   202 
  specimens. 
  The 
  genera 
  of 
  simians 
  known 
  to 
  occur 
  in 
  the 
  region 
  

   are 
  Cebus, 
  Ateles, 
  Alouatta, 
  Aotus, 
  and 
  Adarikina. 
  Each 
  of 
  these 
  

   genera 
  is 
  represented 
  in 
  the 
  collection 
  by 
  one 
  species. 
  

  

  The 
  greater 
  part 
  of 
  this 
  report 
  is 
  devoted 
  to 
  a 
  taxonomic 
  review 
  of 
  

   the 
  whole 
  of 
  that 
  group 
  of 
  the 
  genus 
  Cehus 
  which 
  includes 
  the 
  species 
  

   collected. 
  The 
  other 
  cebid 
  genera, 
  Ateles, 
  Alouatta, 
  and 
  Aotus, 
  are 
  

   treated 
  with 
  more 
  circumscription, 
  as 
  the 
  taxonomic 
  problems 
  affect- 
  

   ing 
  them 
  are 
  less 
  embroiled. 
  The 
  bare-faced 
  tamarins, 
  genus 
  Mari- 
  

   kina, 
  which 
  include 
  the 
  three 
  species 
  of 
  northern 
  Colombian 
  marmo- 
  

   sets, 
  are 
  revised. 
  The 
  remaining 
  tamarins 
  of 
  the 
  same 
  genus, 
  and 
  

   the 
  little 
  lion-monkeys, 
  genus 
  Leontocebus, 
  are 
  also 
  discussed 
  and 
  

   arranged 
  by 
  species. 
  

  

  Nearly 
  all 
  pertinent 
  type 
  specimens 
  preserved 
  in 
  this 
  country, 
  in 
  

   London, 
  and 
  in 
  Paris 
  have 
  been 
  examined. 
  For

   this 
  material,

  well 
  as
