  It 
  will 
  be 
  seen 
  from 
  this 
  list 
  that 
  the 
  birds 
  still 
  existing 
  in 
  

   the 
  Chatham 
  group 
  are 
  55 
  in 
  number, 
  besides 
  two 
  introduced 
  

   European 
  species 
  [Alauda 
  arvensis 
  and 
  Passer 
  domesticus). 
  

   Since 
  the 
  publication 
  of 
  the 
  second 
  edition 
  of 
  Sir 
  Walter 
  

   BuUer's 
  'History^ 
  in 
  1889, 
  six 
  new 
  species 
  have 
  been 
  dis- 
  

   covered 
  there, 
  namely, 
  Cyanorhamphus 
  forbesi, 
  Carpophaga 
  

   chathamensis, 
  Porphyria 
  chathamensis, 
  Phalacrocorax 
  rolh- 
  

   schildi, 
  P. 
  onsloivi, 
  and 
  (Edrelata 
  axillaris. 
  There 
  occur 
  

   on 
  the 
  Chatham 
  Islands 
  13 
  species 
  which, 
  so 
  far 
  as 
  is 
  

   known, 
  are 
  endemic. 
  Since 
  Dr. 
  Sharpe 
  has 
  relegated 
  the 
  

   Ocydromus 
  sylvestris, 
  Scl., 
  of 
  Lord 
  Howe's 
  Island, 
  to 
  the 
  

   genus 
  Cabalus, 
  the 
  Chatham 
  Islands 
  have 
  been 
  deprived 
  of 
  

   their 
  sole 
  supposed 
  endemic 
  genus 
  among 
  their 
  living 
  forms. 
  

   My 
  investigations 
  among 
  the 
  remains 
  of 
  their 
  former, 
  but 
  

   now 
  extinct, 
  bird-life 
  have 
  brought 
  to 
  light 
  the 
  fact 
  that 
  

   many 
  other 
  species, 
  some 
  of 
  them 
  well-known 
  New-Zealand 
  

   birds, 
  were 
  once 
  abundant 
  in 
  these 
  islands. 
  It 
  may 
  be 
  in- 
  

   teresting 
  to 
  enumerate 
  the 
  extinct 
  species 
  so 
  far 
  identified.
