  Carpenter's 
  Reports 
  to 
  the 
  British 
  Association 
  ; 
  my 
  own 
  collections 
  from 
  

   Plover 
  Bay, 
  and 
  Norton 
  Sound, 
  and 
  southerly, 
  from 
  1865 
  to 
  1873 
  ; 
  collections 
  

   from 
  Cape 
  Espenberg 
  and 
  Grantley 
  Harbor 
  by 
  Captain 
  E. 
  E. 
  Smith, 
  and 
  from 
  

   Icy 
  Cape 
  by 
  Captain 
  T. 
  W. 
  Williams, 
  in 
  1873. 
  A 
  few 
  other 
  species 
  known 
  to 
  

   be 
  found 
  in 
  that 
  region 
  have 
  been 
  added 
  from 
  various 
  sources. 
  Synonymy, 
  in 
  

   general, 
  has 
  been 
  waived, 
  except 
  for 
  the 
  purpose 
  of 
  referring 
  to 
  a 
  figure. 
  The 
  

   region 
  is 
  probably 
  a 
  rich 
  one, 
  especially 
  in 
  forms 
  of 
  the 
  Buccinoid 
  and 
  C/iryso- 
  

   domoid 
  types, 
  and 
  it 
  is 
  to 
  be 
  hoped 
  that 
  it 
  may 
  be 
  more 
  thoroughly 
  explored 
  

   before 
  long. 
  The 
  large 
  collections 
  of 
  species 
  made 
  by 
  Dr. 
  Stimpson 
  in 
  this 
  re- 
  

   gion 
  were 
  lost 
  in 
  the 
  Chicago 
  fire, 
  and 
  contained 
  many 
  unpublished 
  forms. 
  It 
  

   is, 
  therefore, 
  particularly 
  desirable 
  that 
  more 
  material 
  should 
  be 
  obtained, 
  and 
  

   no 
  one 
  is 
  better 
  able 
  to 
  contribute 
  to 
  our 
  knowledge 
  in 
  this 
  respect 
  than 
  our 
  

   hardy 
  whalers. 
  Doubtfully 
  identified 
  species 
  and 
  those 
  which 
  may 
  be 
  syno- 
  

   nymous 
  with 
  others, 
  are 
  marked 
  with 
  an 
  asterisk. 
  Those 
  species 
  which 
  may 
  

   have 
  been 
  erroneously 
  attributed 
  to 
  the 
  region 
  referred 
  to, 
  have 
  in 
  general 
  been 
  

   omitted.
