  Remarks. 
  — 
  One 
  specimen 
  (U.S.N.M. 
  No. 
  261319) 
  from 
  the 
  Paria 
  

   Peninsula, 
  Venezuela, 
  is 
  distinctly 
  paler 
  and 
  resembles 
  more 
  nearly 
  

   the 
  figure 
  of 
  the 
  Sajou 
  mdle 
  of 
  Cuvier 
  than 
  any 
  other 
  specimen 
  ex- 
  

   amined.

  Distribution 
  (map, 
  fig. 
  54). 
  — 
  Amazonian 
  region 
  of 
  Brazil, 
  Colombia, 
  

   Venezuela, 
  Ecuador, 
  and 
  Peru; 
  banks 
  of 
  upper 
  Rio 
  Orinoco 
  and 
  the 
  

   Lake 
  Maracaibo 
  drainage 
  basin 
  in 
  Venezuela 
  and 
  Colombia; 
  lower 
  

   Simi, 
  Rancheria, 
  and 
  Cauca-Magdalena 
  dramage 
  areas 
  of 
  Colombia; 
  

   Pacific 
  drainage 
  areas 
  of 
  northwestern 
  Ecuador; 
  island 
  of 
  Trinidad. 
  

   Altitudinal 
  range 
  from 
  sea 
  level 
  to 
  not 
  over 
  2,000 
  meters 
  above. 
  

  

  There 
  is 
  no 
  evidence 
  that 
  members 
  of 
  the 
  species 
  exist 
  in 
  northern 
  

   Venezuela 
  outside 
  the 
  Lake 
  Maracaibo 
  Basin. 
  Micos 
  of 
  this 
  area 
  

   may 
  be 
  regarded 
  as 
  representing 
  an 
  extension 
  of 
  range 
  of 
  the 
  fraction 
  

   of 
  the 
  species 
  occupying 
  the 
  Cauca-Magdalena 
  and 
  Rancheria 
  drainage 
  

   areas 
  of 
  Colombia. 
  C. 
  albifrons 
  leucocephalus 
  has 
  a 
  trans-Andean 
  

   distribution. 
  It 
  ranges 
  from 
  the 
  Rio 
  Zulia, 
  an 
  affluent 
  of 
  Lake 
  

   Maracaibo, 
  across 
  the 
  Cordillera 
  Oriental 
  to 
  the 
  Magdalena 
  Valley. 
  

   The 
  race 
  of 
  the 
  eastern 
  base 
  of 
  the 
  Sierra 
  de 
  Perija, 
  Venezuela, 
  

   probably 
  grades 
  into 
  malitiosus 
  of 
  the 
  Sierra 
  Nevada 
  de 
  Santa 
  Marta, 
  

   Colombia. 
  Immediately 
  south 
  of 
  where 
  the 
  range 
  of 
  these 
  two 
  forms 
  

   may 
  meet 
  is 
  the 
  region 
  of 
  the 
  Rio 
  Cesar, 
  inhabited 
  by 
  a 
  third 
  race. 
  

   So 
  far 
  as 
  available 
  records 
  show, 
  there 
  is 
  no 
  contiguity 
  between 
  the 
  

   range 
  of 
  that 
  part 
  of 
  the 
  species 
  mentioned 
  above 
  and 
  that 
  of 
  repre- 
  

   sentatives 
  of 
  the 
  species 
  known 
  to 
  occur 
  in 
  the 
  upper 
  Rio 
  Orinoco 
  

   and 
  in 
  the 
  Amazonian 
  regions. 
  Nevertheless, 
  the 
  former 
  must 
  have 
  

   been 
  derived 
  from 
  the 
  latter, 
  and 
  the 
  distributional 
  gap 
  may 
  be 
  more
