  Mr. 
  Carriker 
  who 
  obtained 
  this 
  species 
  in 
  Venezuela 
  states: 
  

   "this 
  monkey 
  I 
  found 
  to 
  be 
  by 
  far 
  the 
  most 
  abundant 
  and 
  least 
  

   wary 
  of 
  the 
  three 
  species 
  in 
  all 
  places 
  visited 
  on 
  the 
  Caura 
  and 
  in 
  

   northeastern 
  Venezuela. 
  However 
  they 
  do 
  not, 
  as 
  a 
  rule, 
  ascend 
  to 
  

   any 
  great 
  altitude, 
  preferring 
  the 
  forest 
  along 
  the 
  streams 
  or 
  anywhere 
  

   in 
  the 
  comparatively 
  low 
  country. 
  Almost 
  invariably 
  they 
  will 
  be 
  seen 
  

   in 
  small 
  troops 
  of 
  from 
  a 
  half 
  dozen 
  to 
  twenty, 
  very 
  seldom 
  a 
  pair 
  

   alone. 
  While 
  not 
  as 
  shy 
  as 
  the 
  other 
  species, 
  they 
  are 
  nevertheless 
  far 
  

   from 
  easy 
  to 
  shoot, 
  and 
  must 
  be 
  taken 
  by 
  surprise, 
  or 
  else 
  they 
  rapidly 
  

   make 
  their 
  escape 
  through 
  the 
  high 
  tree-tops. 
  They 
  tame 
  easily 
  and 
  

   make 
  interesting 
  and 
  affectionate 
  pets 
  if 
  not 
  mistreated. 
  

  

  "Rare 
  in 
  the 
  region 
  of 
  El 
  Hacha 
  and 
  Aroa. 
  They 
  live 
  up 
  on 
  the 
  

   slopes 
  above 
  the 
  valley, 
  descending 
  occasionally 
  to 
  feed 
  on 
  the 
  corn, 
  

   etc., 
  planted 
  on 
  the 
  lower 
  slopes."
