﻿inhabiting 
  the 
  Chatham 
  Islands.

  The 
  head 
  of 
  the 
  type 
  is, 
  however, 
  unknown. 
  Among 
  the 
  

   bones 
  from 
  the 
  Chatham 
  Islands, 
  collected 
  by 
  myself, 
  were 
  

   several 
  heads 
  which 
  I 
  was 
  unable 
  to 
  allocate 
  to 
  any 
  known 
  

   genus. 
  Of 
  these 
  I 
  have 
  recently 
  received 
  additional 
  speci- 
  

   mens, 
  and 
  I 
  have 
  been 
  able 
  to 
  decide 
  that 
  they 
  belong 
  to 
  the 
  

   bird 
  the 
  limb-bones 
  and 
  pelves 
  of 
  which 
  I 
  had 
  identified 
  as 
  

   belonging 
  to 
  Fulica 
  newtoni. 
  They 
  indicate 
  a 
  form 
  of 
  Rail 
  

   so 
  aberrant 
  that 
  they 
  must 
  be 
  removed 
  from 
  the 
  genus 
  

   Fulica. 
  The 
  most 
  remarkable 
  points 
  in 
  the 
  structure 
  of 
  

   the 
  skull 
  are 
  its 
  extraordinarily 
  curved 
  form, 
  the 
  deeply 
  

   marked 
  glandular 
  impressions 
  over 
  the 
  eyes, 
  and 
  the 
  great 
  

   pneumaticity 
  of 
  the 
  frontal 
  bones. 
  

  

  Remains 
  of 
  a 
  species, 
  if 
  not 
  the 
  same 
  a 
  very 
  closely 
  related 
  

   one, 
  have 
  been 
  discovered 
  by 
  Mr. 
  A. 
  Hamilton 
  in 
  New 
  

   Zealand 
  in 
  the 
  cave 
  in 
  Otago, 
  whence 
  he 
  obtained 
  some 
  

   remarkably 
  complete 
  skeletons 
  of 
  Aptornis 
  (of 
  which 
  a 
  

   specimen 
  has 
  lately 
  been 
  acquired 
  for 
  the 
  Geological 
  

   Department 
  of 
  the 
  British 
  Museum) 
  associated 
  with 
  remains 
  

   of 
  Stringops, 
  Notornis, 
  Dinornis, 
  Harpagornis, 
  and 
  other, 
  

   now 
  vanished, 
  species 
  of 
  its 
  bird-fauna.

  This 
  bird 
  must 
  have 
  been 
  abundant 
  at 
  one 
  time 
  in 
  "Whare- 
  

   kauri, 
  to 
  which 
  island 
  it 
  was 
  apparently 
  confined.

   One

  occur 
  in 
  the

   belong 
  to 
  this 
  species.

  This

  I

   in 
  New 
  Zealand 
  {cf. 
  Trans.

  It 
  must 
  

   have 
  been 
  enormously 
  common 
  on 
  Wharekauri.
