  intermediate 
  between 
  aequatorialis 
  and 
  malitiosus. 
  The 
  altitude 
  of 
  

   7,000 
  feet 
  given 
  by 
  Allen 
  for 
  his 
  Gualea 
  specimen 
  appears 
  to 
  be 
  too 
  

   high 
  for 
  the 
  range 
  of 
  the 
  species. 
  

  

  It 
  cannot 
  yet 
  be 
  demonstrated 
  where 
  the 
  range 
  of 
  aequatorialis 
  

   meets 
  that 
  of 
  any 
  other 
  member 
  of 
  the 
  species 
  albifrons. 
  Possibly 
  it 
  

   grades 
  into 
  what 
  may 
  be 
  regarded 
  as 
  hypoleucus 
  somewhere 
  along 
  the 
  

   Pacific 
  coast 
  of 
  Colombia. 
  On 
  the 
  other 
  hand, 
  the 
  range 
  of 
  aequa- 
  

   torialis 
  meets, 
  if 
  it 
  does 
  not 
  actually 
  overlap, 
  that 
  of 
  Cehus 
  capucinus 
  

   in 
  the 
  mountains 
  of 
  western 
  Ecuador. 
  The 
  writer 
  found 
  the 
  black 
  

   white-fronted 
  species 
  (capucinus) 
  in 
  the 
  vicinity 
  of 
  Paramba 
  (alti- 
  

   tude, 
  about 
  1,000 
  meters) 
  on 
  the 
  western 
  slope 
  of 
  the 
  Cordillera 
  

   Occidental, 
  in 
  Ecuador. 
  So 
  far 
  as 
  known, 
  Cebus 
  capucinus 
  does 
  not 
  

   occur 
  on 
  the 
  Ecuadorian 
  coast.
