  all 
  belong 
  to 
  the 
  same 
  species 
  as 
  that 
  I 
  am 
  now 
  describing 
  

   from 
  the 
  Chatbam 
  Islands. 
  But 
  there 
  can 
  be 
  as 
  little 
  doubt 
  

   that 
  they 
  do 
  not 
  agree 
  with 
  Sir 
  Walter 
  Buller's 
  description. 
  

   That 
  author 
  says 
  : 
  — 
  " 
  The 
  adult 
  is 
  similar 
  to 
  P. 
  carunculatns, 
  

   but 
  conspicuously 
  less 
  ; 
  it 
  is 
  vAthout 
  carunculations 
  ; 
  posterior 
  

   portion 
  of 
  back 
  slightly 
  marked 
  ^ith 
  a 
  white 
  spot. 
  Crovrn 
  

   of 
  the 
  head, 
  shoulders, 
  feathers 
  composing 
  the 
  mantle, 
  wing- 
  

   coverts, 
  and 
  scapulars 
  bronzy 
  brvwn, 
  with 
  a 
  green 
  gloss 
  in 
  

   certain 
  lights 
  ; 
  hind 
  part 
  and 
  sides 
  of 
  neck, 
  lower 
  portion 
  of 
  

   back, 
  rump, 
  and 
  thighs 
  blue-black 
  with 
  a 
  fine 
  metallic 
  gloss/'' 
  

   He 
  describes 
  also 
  on 
  the 
  same 
  jjage 
  a 
  young 
  of 
  P. 
  colensoi. 
  

   His 
  species 
  is 
  described 
  from 
  the 
  Auckland 
  Islands, 
  and, 
  on 
  

   account 
  of 
  Baron 
  von 
  HiigeFs 
  specimens, 
  from 
  the 
  south 
  

   of 
  Xew 
  Zealand 
  also. 
  Sir 
  Walter 
  also 
  examined 
  many 
  of 
  

   the 
  " 
  twenty 
  or 
  more 
  specimens 
  " 
  collected 
  in 
  the

   Islands

  Eggs. 
  — 
  This 
  bird, 
  my 
  correspondent 
  informs 
  me, 
  lays 
  three 
  

   eggs. 
  In 
  form 
  they 
  vary 
  from 
  ellipso-ovoid 
  to 
  cylindrical 
  

   ovate. 
  Size 
  :

   The 
  ground-colour 
  is 
  that 
  of 
  all 
  Cormorants' 
  eggs, 
  milky 
  

   blue, 
  plastered 
  with 
  patches 
  of 
  cream-coloured 
  chalk. 
  

  

  Of 
  the 
  Cormorants, 
  therefore, 
  in 
  the 
  Southern 
  Seas, 
  having 
  

   a 
  white 
  underside 
  and 
  a 
  steel-blue 
  hind 
  neck 
  and 
  back, 
  there 
  

   appear 
  to 
  be 
  eight 
  distinct 
  species, 
  which 
  I 
  may 
  characterize 
  

   shortly, 
  while 
  on 
  the 
  subject, 
  as 
  follows 
  :
