  I 
  have 
  already 
  mentioned 
  that 
  I 
  found 
  the 
  broken 
  eggs 
  of 
  

   some 
  Terns 
  on 
  the 
  nests 
  of 
  the 
  Flamingoes 
  ; 
  but 
  I 
  regret 
  

   that 
  I 
  was 
  so 
  much 
  occupied 
  and 
  excited 
  by 
  the 
  Flamin- 
  

   goes 
  and 
  their 
  breeding-place 
  that 
  I 
  did 
  not 
  pay 
  suffi- 
  

   cient 
  attention 
  to 
  the 
  Terns 
  to 
  say 
  with 
  certainty 
  whether

   that 
  came 
  near 
  to 
  me 
  and 
  were 
  shot 
  were 
  of 
  the 
  latter 
  

   species, 
  and 
  therefore 
  I 
  am 
  quite 
  sure 
  that 
  they 
  breed 
  here 
  

   and 
  that 
  the 
  broken 
  eggs 
  belonged 
  to 
  them.

  These

   full-grown 
  young 
  ones.

  V. 
  General 
  Conclusions. 
  

  

  (1) 
  The 
  three 
  islands 
  of 
  Aruba, 
  Curacao, 
  and 
  Bonaire 
  

   have 
  received 
  the 
  greater 
  number 
  of 
  their 
  birds 
  from 
  the 
  

   South-American 
  continent, 
  but 
  some 
  also 
  from 
  the 
  West 
  

   Indies, 
  for 
  there 
  are 
  many 
  pure 
  West-Indian 
  forms 
  amongst 
  

   them 
  besides 
  the 
  continental 
  ones. 
  

  

  (2) 
  There 
  are 
  striking 
  affinities 
  between 
  the 
  avifauna 
  of 
  

   these 
  islands 
  and 
  that 
  of 
  the 
  islands 
  of 
  St. 
  Thomas 
  and 
  

   St. 
  Croix 
  (Virgin 
  Islands), 
  but 
  no 
  similarity 
  to 
  that 
  of 
  the 
  

   Windward 
  Islands; 
  for 
  example, 
  Conurus 
  pertinax, 
  Elainea 
  

   martinica 
  I'iisii, 
  Icterus 
  icterus^, 
  Tyr 
  annus 
  dominicensisf, 
  

   and 
  Margarops 
  fuscatus 
  occur 
  in 
  both 
  localities. 
  Moreover, 
  

   we 
  have 
  in 
  this 
  avifauna 
  Certhiola 
  uropygialis 
  (of 
  which 
  the 
  

   nearest 
  allies 
  are 
  found 
  on 
  St. 
  Croix 
  and 
  St. 
  Thomas),

  Icterus 
  icterus 
  has 
  been 
  introduced 
  into 
  

   St. 
  Tbomas, 
  but 
  this 
  seems 
  to 
  be 
  doubtful.

  of 
  the 
  Lesser 
  

   Antilles.
