  Millett 
  records 
  both 
  microspheric 
  and 
  megalo- 
  

   spheric 
  specimens 
  from 
  the 
  Malay 
  region. 
  Heron-Allen 
  and 
  Earland 
  

   had 
  it 
  from 
  five 
  stations 
  in 
  their 
  Kerimba 
  Archipelago 
  collections. 
  

   Dakin 
  records 
  it 
  as 
  " 
  sparingly," 
  Gulf 
  of 
  Manaar. 
  Sidobottom's 
  

   specimens 
  are 
  from 
  465 
  fathoms 
  off 
  the 
  East 
  Coast 
  of 
  Australia. 
  

   Heron-Allen 
  and 
  Earland 
  record 
  it 
  from 
  the 
  Antarctic 
  Expedition 
  

   material 
  dredged 
  by 
  the 
  Terra 
  Nova 
  off 
  Three 
  Kings 
  Island, 
  New- 
  

   Zealand, 
  90-120 
  fathoms 
  and 
  from 
  Lord 
  Howe 
  Island 
  in 
  the 
  Pacific. 
  

  

  I 
  have 
  had 
  it 
  from 
  the 
  Pacific 
  from 
  off 
  Japan 
  in 
  44 
  and 
  361 
  fathoms, 
  

   between 
  Yokohama 
  and 
  Guam 
  in 
  1,208 
  fathoms, 
  and 
  in 
  271 
  fathoms 
  

   off 
  the 
  Hawaiian 
  Islands. 
  It 
  occurred 
  at 
  several 
  stations 
  in 
  the 
  

   Samoan 
  collections, 
  most 
  common 
  at 
  the 
  deepest 
  station, 
  50 
  fathoms, 
  

   and 
  at 
  numerous 
  stations 
  in 
  the 
  Philippine 
  region, 
  78-554 
  fathoms. 
  

  

  In 
  the 
  Atlantic 
  it 
  is 
  rare, 
  and 
  the 
  only 
  records 
  are 
  from 
  the 
  western 
  

   tropical 
  portions. 
  It 
  occurred 
  rarely 
  but 
  well 
  developed 
  in 
  the 
  

   shallow^- 
  water 
  material 
  from 
  the 
  Tortugas 
  region, 
  and 
  at 
  a 
  single 
  

   Albatross 
  station 
  off 
  Central 
  America 
  in 
  382 
  fathoms. 
  

  

  There 
  are 
  very 
  few 
  records 
  of 
  its 
  occurrence 
  in 
  the 
  fossil 
  state. 
  

   Schubert 
  records 
  it 
  from 
  the 
  "Neogene" 
  of 
  Sanaibas, 
  in 
  the 
  

   Bismarck 
  Archipelago, 
  and 
  from 
  a 
  "coral-sand" 
  probably 
  Pleistocene 
  

   of 
  Maria 
  Island 
  in 
  the 
  Paumotu 
  group. 
  Yabe 
  and 
  Hanzawa 
  

   record 
  it 
  as 
  rare 
  from 
  the 
  Pliocene 
  shell 
  beds 
  of 
  Nojima, 
  and 
  

   as 
  rare 
  at 
  Nagamura, 
  Japan. 
  Heron-Allen 
  and 
  Earland 
  record 
  

   a 
  questionable 
  specimen 
  from 
  New 
  Zealand 
  of 
  sub-fossil 
  char- 
  

   acter. 
  Halkyard 
  6 
  records 
  the 
  species 
  from 
  the 
  Eocene 
  Blue 
  Marl 
  

   of 
  Biarritz. 
  The 
  editors 
  of 
  Halkyard's 
  paper, 
  Heron-Allen 
  and 
  Ear- 
  

   land, 
  make 
  the 
  following 
  note 
  as 
  to 
  these 
  specimens. 
  " 
  They 
  are 
  

   much 
  longer 
  and 
  narrower 
  than 
  any 
  specimens 
  of 
  S. 
  raphanus 
  that 
  

   we 
  have 
  ever 
  seen, 
  and 
  there 
  is 
  no 
  evidence 
  of 
  any 
  uvigerine 
  com- 
  

   mencement. 
  We 
  should 
  have 
  ascribed 
  them 
  with 
  little 
  hesitation 
  

   to 
  Nodosaria 
  obliqua 
  (Linne)." 
  This 
  then 
  removes 
  from 
  consider- 
  

   ation 
  this 
  Eocene 
  material 
  which 
  is 
  so 
  far 
  out 
  of 
  the 
  known 
  range 
  of 
  

   the 
  species. 
  

  

  The 
  species 
  is 
  in 
  its 
  typical 
  form 
  one 
  of 
  characteristic 
  distribution, 
  

   mainly 
  Indo-Polynesian, 
  ranging 
  from 
  the 
  Kerimba 
  Archipelago 
  

   across 
  the 
  Indian 
  Ocean, 
  extending 
  northward 
  to 
  Japan, 
  Guam, 
  and 
  

   the 
  Hawaiian 
  Islands, 
  and 
  southward 
  to 
  New 
  Zealand. 
  It 
  also 
  

   extends 
  into 
  the 
  western 
  tropical 
  Atlantic, 
  but 
  seems 
  to 
  be 
  rare. 
  As 
  

   a 
  fossil 
  it 
  occurs 
  in 
  the 
  late 
  Tertiary 
  of 
  Japan 
  and 
  the 
  Bismarck 
  

   Archipelago.
