  and 
  had 
  shipped 
  extensive 
  collections 
  home. 
  Knowing 
  the 
  thorough- 
  

   ness 
  with 
  which 
  Platen's 
  work 
  is 
  usually 
  done, 
  it 
  did 
  not 
  seem 
  to 
  us 
  

   worth 
  while, 
  under 
  the 
  circumstances, 
  to 
  give 
  much 
  time 
  to 
  the 
  birds, 
  

   and 
  during 
  that 
  and 
  our 
  subsequent 
  visit 
  to 
  the 
  island 
  we 
  devoted 
  

   ourselves 
  chietly 
  to 
  collecting 
  mammals, 
  reptiles, 
  and 
  land 
  mollusca. 
  

  

  For 
  some 
  unexplained 
  cause 
  lu) 
  account 
  of 
  Platen's 
  collections 
  has 
  

   ever 
  appeared, 
  a 
  fact 
  which 
  is 
  greatly 
  to 
  be 
  regretted. 
  

  

  (^)uite 
  recently 
  Everett 
  undertook 
  au 
  expedition 
  to 
  the 
  island, 
  which 
  

   he 
  was 
  unfortunately 
  c()m])elled 
  to 
  al)andon 
  before 
  it 
  was 
  fairly 
  begun. 
  

  

  Finally, 
  Whitehead 
  has 
  attempted 
  to 
  work 
  the 
  highlands 
  of 
  Mindoro. 
  

   Unfortunately 
  he 
  chose 
  the 
  worst 
  possible 
  mouths 
  for 
  visiting 
  an 
  island 
  

   which 
  has 
  a 
  sufficiently 
  abominable 
  climate 
  at 
  best, 
  and 
  in 
  comparison 
  

   with 
  Avhat 
  he 
  has 
  accomplished 
  in 
  several 
  other 
  localities 
  his 
  results 
  

   are 
  disappointing. 
  

  

  As 
  a 
  result 
  of 
  all 
  this 
  collecting 
  but 
  134 
  species 
  are 
  known 
  from 
  this 
  

   large, 
  well 
  watered, 
  and 
  magnihcently 
  wooded 
  island, 
  and 
  it 
  is 
  certainly 
  

   true 
  that 
  much 
  remains 
  to 
  be 
  done 
  in 
  Mindoi 
  o. 
  

  

  Sixty-four 
  of 
  the 
  known 
  species 
  are 
  strictly 
  Philippine 
  forms. 
  The 
  

   following 
  species 
  are 
  peculiar 
  to 
  the 
  island 
  so 
  far 
  as 
  we 
  at 
  present 
  

   know, 
  though 
  they 
  may 
  be 
  discovered 
  in 
  the 
  at 
  present 
  unknown 
  

   islands 
  Yliii 
  and 
  Lubaug, 
  or 
  in 
  smaller 
  islands 
  near 
  Mindoro.

  Upon 
  comi)aring 
  the 
  remaining 
  species 
  with 
  the 
  corresponding 
  Luzon 
  

   forms, 
  we 
  note 
  that 
  the 
  Mindoro 
  species 
  Phlogoenas 
  i^latenae, 
  Penelo2)kles 
  

   Quindorensis, 
  Loriculus 
  mindorensis,

   respectively. 
  

  

  On 
  the 
  other 
  hand, 
  the 
  following 
  species 
  are 
  common 
  to 
  Luzon 
  and 
  

   Mindoro, 
  most 
  of 
  them 
  being 
  confined 
  to 
  these 
  islands 
  and

  Turning 
  now 
  to 
  the 
  negative 
  differences 
  between 
  the 
  two 
  islands. 
  I 
  

   propose 
  to 
  conhue 
  myself 
  to 
  cases 
  in 
  regard 
  to 
  which 
  there 
  can 
  be 
  no 
  

   doubt, 
  omitting 
  mention 
  of 
  a 
  number 
  of 
  genera 
  which 
  have 
  not 
  been
