  inj^ 
  to 
  Sir 
  W, 
  Biiller^'s 
  

   text 
  (not 
  his 
  plate 
  in 
  the 
  second 
  edition), 
  is 
  of 
  the 
  same 
  

   colour 
  as 
  the 
  back 
  and 
  neck, 
  " 
  dark 
  purplish 
  or 
  steel-blue.'"' 
  

   The 
  carunculations 
  also 
  are 
  developed 
  apparently 
  during 
  the 
  

   breeding-season. 
  Buller's 
  figure 
  of 
  P. 
  imperialis 
  { 
  = 
  P. 
  

   onslowi) 
  has 
  no 
  carunculations, 
  while 
  Sclater's 
  from 
  South 
  

   America 
  shows 
  them. 
  

  

  As 
  the 
  type 
  of 
  P. 
  imperialis 
  of 
  King 
  was 
  a 
  INIagellan 
  

   Straits' 
  specimen, 
  this 
  name 
  must 
  necessarily 
  be 
  retained 
  for 
  

   the 
  South-American 
  form, 
  so 
  that, 
  if 
  Sir 
  W. 
  Buller 
  is 
  right 
  

   in 
  separating 
  the 
  New-Zealand 
  from 
  the 
  Chatham-Island 
  

   birds, 
  under 
  the 
  name 
  of 
  P. 
  carunculatus, 
  the 
  bird 
  from 
  

   the 
  Chatham 
  Islands 
  requires 
  a 
  new 
  name. 
  I 
  have 
  therefore 
  

   taken 
  the 
  liberty 
  of 
  associating 
  with 
  it 
  tiiat 
  of 
  the 
  Earl 
  of 
  

   Onslow, 
  to 
  whom 
  ornithologists 
  are 
  deeply 
  indebted 
  for 
  the 
  

   measures 
  he 
  instituted, 
  when 
  Governor 
  of 
  New 
  Zealand, 
  for 
  

   the 
  protection 
  of 
  the 
  singular 
  but 
  fast-vanishing 
  avifauna 
  

   of 
  those 
  islands, 
  as 
  well 
  as 
  on 
  account 
  of 
  the 
  personal 
  

   interest 
  he 
  has 
  taken 
  in 
  the 
  Phalacrocoraciihe 
  of 
  that 
  colony. 
  

   Mr. 
  r. 
  W. 
  Hutton 
  has 
  proposed 
  to 
  designate 
  the 
  Chatham- 
  

   Island 
  Crowned 
  Shag 
  as 
  P. 
  cirrhatus 
  of 
  Gmelin 
  ; 
  but 
  this 
  is 
  

   inadmissible, 
  if 
  not 
  on 
  other 
  grounds, 
  for 
  the 
  reason 
  that 
  

   Gmelin's 
  type 
  had 
  1-1 
  rectriccs, 
  while 
  P. 
  imperialis, 
  carun- 
  

   culatus, 
  onslowi, 
  colensoi, 
  and 
  rothschildi 
  all 
  have 
  only 
  12. 
  

  

  Phalacrocorax 
  onslowi 
  inhabits 
  Rangitutahi, 
  or 
  the 
  Sisters, 
  

   a 
  few 
  rocky 
  islets 
  to 
  the 
  north 
  of 
  the 
  main 
  island.

  This 
  is 
  a 
  more 
  beautiful 
  species 
  in 
  my 
  estimation 
  than 
  

   any 
  of 
  the 
  others 
  from 
  the 
  Southern 
  Ocean. 
  At 
  first 
  I 
  was 
  

   inclined 
  to 
  place 
  it 
  under 
  P. 
  cole/isoi 
  of 
  Buller, 
  but 
  the 
  de- 
  

   scription 
  given 
  by 
  him 
  in 
  the 
  2nd 
  edit., 
  vol. 
  ii. 
  p. 
  IGl, 
  of 
  his 
  

   ' 
  Birds 
  of 
  New 
  Zealand,' 
  differs 
  in 
  so 
  many 
  respects 
  from 
  

   the 
  bird 
  I 
  have 
  received 
  from 
  the 
  Chatham 
  Islands, 
  that 
  I 
  

   find 
  myself 
  vinder 
  the 
  necessity 
  of 
  describing 
  it 
  as 
  a 
  new 
  

   species 
  under 
  the 
  name 
  of 
  P. 
  rothschildi, 
  in 
  compliment 
  to 
  

   the 
  Hon. 
  Walter 
  Rothschild, 
  who 
  has 
  taken 
  so 
  much 
  interest 
  

   in 
  the 
  birds 
  of 
  the 
  Chatham 
  Islands.
