  who 
  unite 
  these 
  two 
  forms, 
  this 
  statement 
  may 
  appear 
  to 
  be 
  

   a 
  rather 
  bold 
  one. 
  But 
  it 
  is 
  not 
  wrong 
  to 
  say 
  that 
  those 
  

   who 
  cannot 
  distinguish 
  between 
  C. 
  pertinax 
  and 
  C. 
  cerugi- 
  

   nosus 
  are 
  not 
  well 
  acquainted 
  with 
  these 
  birds, 
  I 
  myself 
  did 
  

   not 
  know 
  them 
  when, 
  two 
  years 
  ago, 
  in 
  my 
  ' 
  Katalog 
  Vogels. 
  

   Mus. 
  Senckenberg/ 
  (p. 
  156), 
  I 
  ventured 
  to 
  unite 
  the 
  two 
  

   sj)ecies, 
  having 
  been 
  (like 
  Finsch, 
  Schlegel, 
  and 
  others) 
  

   misled 
  by 
  young 
  specimens 
  of 
  C. 
  pertinax 
  and 
  by 
  inexact 
  

   localities, 
  so 
  that 
  the 
  distribution 
  could 
  not 
  be 
  studied. 
  

  

  With 
  more 
  material 
  at 
  hand 
  it 
  might 
  not 
  be 
  wrong 
  to 
  

   regard 
  this 
  new 
  form 
  as 
  a 
  subspecies 
  of 
  C. 
  (srnginosus, 
  as 
  it 
  

   is 
  close 
  to 
  it, 
  and 
  specimens 
  might 
  easily 
  be 
  found 
  that 
  very 
  

   nearly 
  approach 
  it, 
  but 
  I 
  prefer 
  to 
  keep 
  it 
  as 
  a 
  species, 
  all 
  the 
  

   more 
  on 
  account 
  of 
  its 
  isolated 
  habitat. 
  

  

  C. 
  arubensis 
  is 
  very 
  common 
  everywhere 
  on 
  Aruba, 
  The 
  

   first 
  morning 
  when 
  out 
  shooting 
  with 
  my 
  friend 
  Dr. 
  Cole, 
  I 
  

   obtained 
  a 
  specimen 
  of 
  it. 
  Thinking 
  that 
  it 
  was 
  the 
  common 
  

   continental 
  form, 
  I 
  was 
  content 
  to 
  pick 
  up 
  a 
  specimen 
  occa- 
  

   sionally, 
  and 
  brought 
  home 
  four 
  skins 
  only. 
  My 
  much 
  

   honoured 
  friend. 
  Count 
  Tommaso 
  Salvadori, 
  first 
  called 
  my 
  

   attention 
  to 
  the 
  light-coloured 
  foreheads 
  and 
  cheeks 
  in 
  my 
  

   skins 
  as 
  soon 
  as 
  he 
  saw 
  them, 
  and 
  I 
  was 
  glad 
  that 
  I 
  found 
  

   the 
  surmises 
  of 
  this 
  great 
  ornithologist 
  well 
  founded, 
  

  

  C. 
  arubensis 
  is 
  similar 
  in 
  its 
  habits 
  and 
  screaming 
  voice 
  to 
  

   C. 
  pertinax, 
  and 
  also 
  lays 
  its 
  eggs 
  in 
  holes 
  dug 
  out 
  in 
  

   old 
  ants^ 
  nests 
  and 
  trees, 
  and 
  in 
  the 
  natural 
  caves 
  and 
  

   holes 
  in 
  the 
  lime 
  rocks. 
  Its 
  food 
  consists 
  mostly 
  of 
  the 
  

   fruits 
  of 
  Cereus, 
  Melocactus, 
  and 
  other 
  plants.
