  Adult 
  male 
  and 
  female. 
  Forehead 
  pale 
  yellow 
  for 
  about 
  

   0'3 
  inch; 
  top 
  of 
  the 
  head 
  distinctly 
  tinged 
  with 
  blue; 
  

   circle 
  round 
  the 
  eyes 
  very 
  narrow 
  above^ 
  broader 
  below, 
  

   pale 
  orange-yellow; 
  lores, 
  cheeks, 
  and 
  sides 
  of 
  the 
  head 
  

   mixed 
  light 
  brown 
  and 
  very 
  pale 
  orange-yellow, 
  the 
  feathers, 
  

   especially 
  those 
  on 
  the 
  ear-coverts, 
  being 
  yellowish 
  in 
  the 
  

   middle 
  and 
  bordered 
  with 
  brown; 
  throat 
  and 
  upper 
  breast 
  

   yellowish 
  brown. 
  Of 
  the 
  same 
  size 
  as 
  Conurus 
  ceruginosus, 
  

   but 
  tail 
  longer 
  as 
  a 
  rule. 
  

  

  This 
  form 
  of 
  Conurus 
  is 
  closely 
  allied 
  to 
  C. 
  ceruginosus 
  

   from 
  Guiana 
  and 
  Venezuela, 
  from 
  which 
  it 
  differs 
  only 
  in 
  

   the 
  lighter 
  colour 
  of 
  the 
  forehead, 
  sides 
  of 
  the 
  head, 
  and 
  

   throat, 
  and 
  I 
  believe 
  also 
  in 
  a 
  somewhat 
  longer 
  tail. 
  As 
  my 
  

   four 
  specimens 
  from 
  Aruba 
  differ 
  in 
  these 
  points 
  from 
  nine 
  

   skins 
  from 
  British 
  Guiana 
  in 
  Mus. 
  W. 
  Rothschild, 
  from 
  all 
  

   the 
  skins 
  from 
  different 
  localities 
  in 
  the 
  British 
  Museum, 
  

   and 
  from 
  skins 
  from 
  Venezuela 
  in 
  Mus. 
  H. 
  v. 
  Berlepsch, 
  I 
  

   believe 
  I 
  am 
  right 
  in 
  distinguishing 
  it 
  as 
  a 
  new 
  island 
  form.

  given 
  

   as 
  0"28,

  Conurus 
  arubensis 
  might, 
  on 
  account 
  of 
  its 
  somewhat 
  

   yellowish 
  sides 
  of 
  the 
  head, 
  be 
  looked 
  upon 
  as 
  a 
  form 
  inter- 
  

   mediate

  the 
  continental 
  C. 
  ctniginosus
