  Gray's 
  name 
  is 
  misleading, 
  for 
  this 
  race 
  is 
  darker 
  than 
  C. 
  azarce 
  

   generally, 
  and 
  no 
  examples 
  that 
  I 
  have 
  seen 
  are 
  as 
  pale 
  as 
  those 
  to 
  be 
  

   found 
  in 
  Rengger's 
  species. 
  His 
  description 
  also 
  gives 
  no 
  idea 
  of 
  the 
  

   appearance 
  of 
  examples 
  from 
  Peru 
  and 
  Bolivia. 
  The 
  race 
  in 
  color 
  is 
  

   intermediate 
  between 
  C. 
  azaile, 
  and 
  C. 
  versutus 
  from 
  the 
  River 
  Jordao 
  

   in 
  western 
  Minas 
  Geraes. 
  The 
  great 
  peculiarity 
  possessed 
  by 
  this 
  form 
  

   and 
  which 
  distinguishes 
  it 
  at 
  once 
  from 
  the 
  other 
  two, 
  is 
  the 
  extension 
  

   of 
  the 
  white 
  on 
  each 
  side 
  of 
  the 
  head 
  into 
  the 
  black 
  cap, 
  and 
  almost 
  

   forming 
  two 
  black 
  patches, 
  the 
  front 
  one 
  much 
  smaller 
  than 
  the 
  one 
  

   behind. 
  The 
  fingers 
  in 
  most 
  of 
  the 
  specimens 
  are 
  paler 
  than 
  those 
  of 
  

   the 
  two 
  other 
  species, 
  being 
  almost 
  white. 
  The 
  exact 
  range 
  of 
  C. 
  a. 
  

   pallidas 
  is 
  not 
  known, 
  but 
  it 
  was 
  obtained 
  by 
  Kalinowski 
  at 
  Santa 
  Anna 
  

   in 
  Peru 
  and 
  by 
  Bridges 
  in 
  Bolivia. 
  How 
  near 
  it 
  may 
  approach 
  C. 
  

   azartE 
  at 
  Chapada 
  is 
  not 
  known, 
  but 
  it 
  is 
  not 
  improbable 
  that 
  their 
  

   boundaries 
  may 
  overlap 
  at 
  some 
  point 
  between 
  Peru 
  and 
  Matto 
  Grosso.
