  Distribution. 
  — 
  This 
  species 
  is 
  common 
  in 
  the 
  Miocene 
  of 
  Cali- 
  

   fornia. 
  It 
  was 
  described 
  from 
  the 
  Monterey 
  shale, 
  on 
  the 
  Ranchodel 
  

   Encinal, 
  7,000 
  feet 
  south 
  of 
  Asuncion 
  station, 
  San 
  Luis 
  Obispo 
  

   County, 
  California. 
  The 
  outcrop 
  is 
  on 
  Graves 
  Creek. 
  

  

  Three 
  species 
  were 
  described 
  by 
  Bagg 
  from 
  this 
  material. 
  The 
  

   first 
  of 
  these, 
  S. 
  branneri, 
  is 
  the 
  microspheric 
  form 
  of 
  the 
  species, 
  

   the 
  other 
  two, 
  S. 
  calif 
  orniensis 
  and 
  S. 
  elongata, 
  represent 
  the 
  megalo- 
  

   spheric 
  form. 
  I 
  have 
  material 
  from 
  the 
  type 
  locality.

  Description. 
  — 
  Test 
  elongate, 
  cylindrical, 
  chambers 
  of 
  the 
  uniserial 
  

   portion 
  broader 
  than 
  long; 
  sutures 
  not 
  deep 
  but 
  conspicuous; 
  wall 
  

   ornamented 
  by 
  longitudinal 
  costae, 
  not 
  close 
  together 
  and 
  not 
  

   prominent; 
  aperture 
  circular 
  with 
  no 
  neck 
  but 
  a 
  prominent 
  rounded 
  

   lip. 
  

  

  Length 
  up 
  to 
  1 
  mm. 
  

  

  Distribution. 
  — 
  Schwager 
  originally 
  described 
  this 
  species 
  from 
  the 
  

   Pliocene 
  of 
  Kar-Nicobar. 
  9 
  His 
  original 
  figure 
  shows 
  a 
  slender 
  test 
  

   with 
  an 
  elongate 
  neck. 
  Recent 
  specimens 
  have 
  practically 
  no 
  

   neck 
  and 
  are 
  stouter 
  than 
  the 
  typical 
  form. 
  Whether 
  they 
  represent 
  

   a 
  new 
  species 
  or 
  a 
  variety 
  of 
  Sch 
  wager's 
  species 
  is 
  a 
  question. 
  Brady's 
  

   specimens 
  were 
  of 
  this 
  varietal 
  form. 
  His 
  records 
  are 
  "off 
  the 
  coast 
  

   of 
  South 
  America, 
  south 
  of 
  Pernambuco, 
  350 
  fathoms; 
  shore-sand, 
  

   east 
  coast 
  of 
  Madagascar; 
  off 
  Kandavu, 
  Fiji 
  Islands, 
  210 
  fathoms; 
  

   off 
  New 
  Hebrides, 
  125 
  fathoms; 
  Torres 
  Strait, 
  3 
  to 
  11 
  fathoms; 
  off 
  

   Ki 
  Islands, 
  129 
  fathoms; 
  and 
  off 
  the 
  Philippines, 
  95 
  fathoms." 
  

   Millett's 
  records 
  are 
  from 
  the 
  Malay 
  Archipelago 
  and 
  Dakin's 
  from 
  

   Ceylon, 
  both 
  probably 
  based 
  on 
  Brady's 
  figures. 
  Egger's 
  records 
  

   are 
  dubious. 
  I 
  have 
  had 
  this 
  varietal 
  form 
  from 
  off 
  Hawaii, 
  114 
  

   fathoms: 
  off 
  Guam, 
  234 
  fathoms: 
  southeast 
  of 
  the 
  Bonin 
  Islands
