  rothschildi, 
  mihi. 
  Chatham 
  Islands 
  and 
  

  

  south 
  of 
  Ne-w 
  Zealand. 
  This 
  species 
  is 
  at 
  once 
  distin- 
  

   guished 
  by 
  the 
  approximation 
  of 
  the 
  dark 
  plumage 
  of 
  

   the 
  head 
  beneath 
  the 
  throat, 
  leaving 
  a 
  comparatively 
  

   narrow 
  white 
  stripe 
  between 
  them.

  bar 
  and

  4. 
  Phalacrocorax 
  co/ensoi, 
  Buller. 
  Auckland 
  Islands. 
  This 
  

  

  species 
  can 
  be 
  separated 
  from 
  P. 
  rothschildi 
  by 
  the 
  colour 
  

   of 
  its 
  upper 
  parts 
  being 
  bronzy 
  brown 
  instead 
  of 
  steel- 
  

   blue. 
  It 
  has 
  an 
  alar 
  bar 
  and 
  a 
  dorsal 
  spot 
  of 
  white, 
  but 
  

   the 
  adult 
  lias 
  no 
  carunculations 
  and 
  no 
  crest 
  according 
  

   to 
  Sir 
  W. 
  Buller. 
  

  

  5. 
  Phalacrocorax 
  albiventris, 
  Less. 
  Falkland 
  Islands 
  and 
  

  

  Straits 
  of 
  Magellan. 
  In 
  this 
  bird 
  the 
  dark 
  plumage 
  

   of 
  the 
  head 
  commences 
  opposite 
  the 
  gape 
  ; 
  it 
  has 
  no 
  

   plumose 
  line 
  along 
  the 
  centre 
  of 
  the 
  gular 
  pouch 
  and 
  no 
  

   dorsal 
  spot 
  of 
  white, 
  but 
  the 
  alar 
  bar 
  is 
  present. 
  There 
  

   is 
  one 
  specimen 
  in 
  the 
  British 
  Museum 
  Collection, 
  

   inseparable, 
  so 
  far 
  as 
  I 
  can 
  detect, 
  from 
  P. 
  albiventris, 
  

   which 
  has 
  no 
  alar 
  bar. 
  It 
  may 
  be 
  an 
  individual 
  variety, 
  

   or 
  turn 
  out 
  to 
  be 
  of 
  a 
  different 
  species, 
  distinguished 
  

   fi'om 
  P. 
  albiventris 
  by 
  the 
  possession 
  of 
  an 
  alar 
  bar. 
  

  

  6. 
  Phalacrocorax 
  I'ei'rncosus, 
  Cab. 
  Kerguelen 
  Land 
  [and 
  

  

  perhaps 
  N. 
  Zealand]. 
  This 
  bird 
  has 
  neither 
  alar 
  bar 
  nor 
  

   dorsal 
  spot 
  of 
  white, 
  and 
  can 
  be 
  distinguished 
  also 
  by 
  the 
  

   dark 
  plumage 
  of 
  the 
  head 
  commencing 
  at 
  the 
  underside 
  of 
  

   the 
  jaw 
  on 
  the 
  inner 
  side 
  of 
  the 
  ramus 
  of 
  the 
  mandible, 
  

   the 
  dark 
  blue, 
  almost 
  black, 
  plumage 
  of 
  the 
  sides 
  of 
  the 
  

   head 
  being 
  separated 
  by 
  a 
  short 
  wedge 
  of 
  white. 
  The 
  

   top 
  and 
  sides 
  of 
  the 
  head 
  blue. 
  Xo 
  plumose 
  line 
  along 
  

   the 
  centre 
  of 
  gular 
  pouch.
