  E. 
  Hartert 
  exhibited 
  the 
  type-specimens 
  of 
  Hemi- 
  

   gnathus 
  lanaiensis, 
  Rothschild, 
  from 
  Lanai, 
  described 
  at 
  the 
  

   last 
  Meeting 
  of 
  the 
  Club, 
  as 
  well 
  as 
  examples 
  of 
  its 
  

   nearest 
  allies. 
  

  

  Mr. 
  Hartert 
  also 
  exhibited 
  the 
  skin 
  of 
  a 
  Goose, 
  supposed 
  

   by 
  him 
  to 
  be 
  a 
  hybrid 
  between 
  Bernicla 
  brenta 
  and 
  Anser 
  

   albifrons. 
  

  

  Mr, 
  Henry 
  Seebohm 
  gave 
  a 
  short 
  explanation 
  of 
  a 
  theory 
  

   propounded 
  by 
  Dr. 
  Nicholski, 
  of 
  St. 
  Petersburg, 
  to 
  account 
  

   for 
  the 
  variations 
  in 
  the 
  shape 
  of 
  birds' 
  eggs. 
  

  

  Mr. 
  W. 
  R. 
  Ogilvie-Grant 
  made 
  some 
  remarks 
  on 
  the 
  

   classification 
  of 
  the 
  Game-Birds 
  and 
  on 
  the 
  changes 
  of 
  the 
  

   plumage 
  in 
  the 
  Tetraonida. 
  

  

  Mr. 
  ScLATER 
  drew 
  attention 
  to 
  the 
  protected 
  district 
  

   round 
  Aden 
  as 
  being 
  very 
  convenient 
  for 
  an 
  ornithological 
  

   excursion, 
  and 
  a 
  place 
  where 
  it 
  was 
  evident, 
  from 
  Lieut. 
  

   Barnes's 
  recent 
  article 
  in 
  ' 
  The 
  Ibis,' 
  that 
  much 
  more 
  good 
  

   work 
  remained 
  to 
  be 
  done.
