  p.

  like

  7. 
  Elminius 
  sinuatus, 
  sp. 
  nov. 
  

  

  Smooth, 
  conical 
  or 
  depressed 
  ; 
  parietes 
  of 
  each 
  valve 
  with 
  two 
  

   broad 
  rounded 
  folds, 
  and 
  faint 
  transverse 
  striations 
  ; 
  white 
  ; 
  sutures 
  

   always 
  distinctly 
  defined. 
  Scuta 
  with 
  the 
  occludeut 
  margin 
  smooth 
  ; 
  

   adductor 
  ridge 
  obsolete 
  ; 
  basal 
  margin 
  longer 
  than 
  the 
  tergal 
  margin. 
  

   Terga 
  with 
  a 
  long 
  spur 
  continuous 
  with 
  the 
  scutal 
  margin 
  ; 
  crest

  Although 
  the 
  opercular 
  valves 
  are 
  almost 
  identical 
  with 
  those 
  of 
  

   E. 
  modestus, 
  the 
  wall 
  valves 
  are 
  so 
  different 
  and 
  so 
  constant 
  that 
  I 
  

   cannot 
  doubt 
  the 
  distinctness 
  of 
  the 
  two 
  species.
