  The 
  specimen 
  is 
  in 
  new 
  pela.ge, 
  its 
  coloration 
  unusual. 
  The 
  fine 
  

   ticking 
  on 
  the 
  median 
  dorsal 
  region 
  recalls 
  the 
  condition 
  characteristic 
  

   of 
  Cebus 
  nigrivittatus. 
  In 
  this 
  species, 
  however, 
  the 
  ticking 
  is 
  much 
  

   coarser, 
  the 
  hairs 
  longer 
  and 
  laxer, 
  the 
  amiulations 
  more 
  sharply 
  con- 
  

   trasted 
  in 
  color. 
  The 
  above 
  described 
  brown 
  streaks 
  on 
  side 
  of 
  face 
  

   extend 
  from 
  the 
  brown 
  eye 
  brows 
  across 
  jowls. 
  In 
  Cebus 
  apella, 
  the 
  

   characteristic 
  dark 
  line 
  is 
  immediately 
  in 
  front 
  of 
  ears 
  and 
  extends 
  

   from 
  crown 
  to 
  beneath 
  chin.
