  o'f 
  eggs 
  varied 
  from 
  two 
  to 
  four. 
  The 
  nests 
  were 
  rounded 
  depressions 
  in 
  the 
  

   turf, 
  usually 
  found 
  in 
  low 
  and 
  marshy 
  localities. 
  It 
  is 
  a 
  summer 
  visitor, 
  and 
  we 
  

   were 
  unable 
  to 
  find 
  it 
  anywhere 
  in 
  the 
  islands 
  except 
  at 
  Kyska 
  — 
  a 
  somewhat 
  

   singular 
  fact. 
  Had 
  it 
  occurred 
  at 
  any 
  of 
  the 
  other 
  stations 
  visited, 
  we 
  should 
  

   probably 
  have 
  detected 
  it. 
  It 
  is 
  not 
  found 
  at 
  Unalashka.

  A 
  summer 
  resident, 
  breeding 
  throughout 
  the

  Islands.

  A 
  species 
  of 
  plover, 
  or 
  sandpiper, 
  with 
  a 
  neatly 
  white 
  body 
  and 
  dark 
  wings, 
  

   about 
  the 
  size 
  of 
  the 
  last 
  species, 
  was 
  seen 
  on 
  two 
  occasions 
  at 
  Attu, 
  in 
  June. 
  

   Unfortunately 
  we 
  were 
  unable 
  to 
  obtain 
  a 
  specimen, 
  and 
  we 
  did 
  not 
  see 
  it 
  any- 
  

   where 
  else.

  This 
  species 
  was, 
  on 
  the 
  9th 
  of 
  June, 
  again 
  obtained 
  at 
  Unalashka, 
  where 
  it 
  

   breeds. 
  It 
  is 
  a 
  summer 
  resident, 
  and 
  has 
  not 
  been 
  observed 
  to 
  the 
  westward 
  of 
  

   this 
  point, 
  though 
  it 
  ranges 
  north 
  to 
  the 
  Yukon.

  Mr. 
  Thompson, 
  an 
  otter-hunter 
  who 
  wintered 
  in 
  Sannakh 
  Island, 
  1872-3, 
  

   reports 
  that 
  he 
  killed 
  three 
  of 
  these 
  birds 
  in 
  September, 
  1872, 
  and 
  that 
  they 
  

   were 
  not 
  uncommon 
  during 
  the 
  autumn. 
  They 
  have 
  not 
  been 
  reported 
  from 
  any 
  

   part 
  of 
  the 
  Aleutian 
  chain 
  proper.

  These 
  birds 
  are 
  reported 
  as 
  occurring 
  in 
  small 
  numbers, 
  spring 
  and 
  fall 
  — 
  during 
  

   their 
  northern 
  and 
  southern 
  migrations 
  — 
  at 
  Attu, 
  Unalashka, 
  and 
  Sannakh. 
  I 
  

   have 
  not 
  heard 
  of 
  them 
  at 
  intermediate 
  points, 
  and 
  as 
  they 
  make 
  no 
  stay, 
  they 
  

   can 
  only 
  be 
  regarded 
  as 
  casual 
  visitors.

  This 
  bird, 
  like 
  the 
  last 
  species, 
  passes 
  the 
  islands 
  in 
  its 
  annual 
  migrations, 
  and 
  

   does 
  not 
  breed 
  to 
  the 
  eastward 
  of 
  Amchitka. 
  Unlike 
  the 
  Gambellu, 
  however, 
  

   a 
  small 
  number 
  do 
  remain 
  and 
  breed 
  on 
  the 
  Semichi 
  Islands 
  near 
  Attu, 
  Kyska, 
  

   and 
  Amchitka. 
  Eggs 
  of 
  this 
  species 
  were 
  obtained 
  on 
  the 
  Semichi 
  Islands, 
  

   June 
  15th, 
  and 
  young, 
  unfledged 
  goslings 
  on 
  Kyska, 
  July 
  10th. 
  It 
  is 
  not 
  abun- 
  

   dant, 
  however, 
  and 
  breeds 
  on 
  the 
  highest 
  bill-tops, 
  and 
  not, 
  as 
  in 
  more 
  northern 
  

   regions, 
  on 
  the 
  lowlands. 
  It 
  has 
  also 
  been 
  reported 
  as 
  a 
  casual 
  visitor 
  at 
  the 
  

   Pribyloff 
  Islands. 
  On 
  our 
  return 
  to 
  the 
  coast 
  of 
  California, 
  in 
  the 
  latter 
  part 
  

   of 
  October, 
  enormous 
  flocks 
  of 
  this 
  species 
  were 
  seen 
  about 
  100 
  miles 
  off 
  shore? 
  

   from 
  the 
  vessel, 
  flying 
  south, 
  frequently 
  alighting 
  in 
  the 
  water 
  near 
  the 
  ship.
