  nearly 
  brachycephalic, 
  that 
  of 
  martinsi 
  decidedly 
  dolichocephalic. 
  

   Altogether 
  leucopus 
  is 
  smaller. 
  

  

  Three 
  specimens 
  of 
  leucopus 
  labeled 
  as 
  being 
  from 
  Puerto 
  Estrella, 
  

   right 
  bank 
  of 
  Rio 
  Magdalena, 
  and 
  collected 
  by 
  H. 
  M. 
  Curran, 
  must 
  

   have 
  been 
  taken 
  on 
  the 
  left 
  bank 
  of 
  the 
  river. 
  The 
  species 
  does 
  not 
  

   naturally 
  occur 
  anywhere 
  on 
  the 
  right 
  bank 
  of 
  the 
  Magdalena 
  though 
  

   it 
  is 
  abundant 
  along 
  the 
  wooded 
  edge 
  of 
  the 
  left 
  bank. 
  M. 
  A. 
  Car- 
  

   riker, 
  Jr. 
  {in 
  epist.), 
  reports 
  the 
  occurrence 
  of 
  leucopus 
  above 
  Simiti, 
  

   Cordillera 
  Central, 
  altitude 
  3,200 
  feet. 
  No 
  other 
  species 
  of 
  marmoset 
  

   inhabits 
  any 
  part 
  of 
  the 
  range 
  of 
  M. 
  leucopus. 
  There 
  is 
  an 
  immense 
  

   geographic 
  hiatus 
  between 
  leucopus 
  and 
  its 
  nearest 
  relatives, 
  martinsi 
  

   and 
  bicolor, 
  both 
  of 
  the 
  Amazonian 
  region. 
  Local 
  name 
  of 
  M. 
  leucopus 
  

   is
