  Test 
  about 
  twice 
  as 
  long 
  as 
  broad, 
  greatest 
  breadth 
  at 
  the 
  apertural 
  

   end, 
  thence 
  gradually 
  tapering 
  to 
  the 
  initial 
  end; 
  chambers 
  distinct; 
  

   sutures 
  somewhat 
  depressed, 
  strongly 
  curved; 
  wall 
  ornamented 
  with 
  

   about 
  fifteen 
  lamellate 
  costae 
  which 
  may 
  continue 
  onto 
  the 
  last- 
  

   formed 
  chamber; 
  apertural 
  characters 
  obscure. 
  

  

  Length

  (Cushman

   lected 
  by 
  W.

  This 
  may 
  be 
  distinguished 
  from 
  S. 
  collomi 
  by 
  its 
  smaller 
  size 
  and 
  

   greater 
  number 
  of 
  costae. 
  It 
  is 
  nearest 
  the 
  form 
  I 
  have 
  described 
  

   from 
  the 
  Panama 
  Canal 
  Zone 
  as 
  S. 
  raphanus 
  (Parker 
  and 
  Jones), 
  

   var. 
  transversus 
  Cushman. 
  

  

  It 
  is 
  named 
  for 
  Ralph 
  D. 
  Reed, 
  geologist 
  of 
  California, 
  under 
  whose 
  

   direction 
  the 
  material 
  was 
  collected.

  at 
  all 
  curved; 
  wall

   mented 
  with 
  about 
  fifteen 
  very 
  low 
  costae, 
  not 
  at 
  all 
  lamellate, 
  not 
  

   continuing 
  onto 
  the 
  last-formed 
  chamber; 
  aperture

  a 
  very

   cylindrical

  slight 
  phialine

  This 
  species 
  may 
  be 
  distinguished 
  from 
  S. 
  reedi 
  by 
  the 
  much 
  lower 
  

   and 
  less 
  prominent 
  costae, 
  and 
  the 
  lack 
  of 
  curvature 
  in 
  the 
  sutures. 
  

  

  It

  named
