  This 
  species 
  is 
  of 
  the 
  same 
  form 
  as 
  S. 
  incerta, 
  but 
  is 
  peculiar 
  in 
  

   having 
  the 
  marginal 
  limbs 
  of 
  the 
  inner 
  cone 
  quite 
  lateral, 
  the 
  surface 
  

   on 
  each 
  side 
  the 
  central 
  ventral 
  groove 
  regularly 
  convex, 
  and 
  

   a 
  different 
  kind 
  of 
  striation. 
  Another 
  distinguishing 
  feature 
  is 
  the 
  

   presence 
  of 
  longitudinal 
  striae 
  (fig. 
  8) 
  down 
  the 
  middle 
  of 
  the 
  dorsal 
  

   surface. 
  These 
  are 
  particularly 
  strong 
  towards 
  the 
  posterior 
  end 
  of 
  

   the 
  largest 
  specimen 
  examined, 
  but 
  they 
  continue 
  the 
  whole 
  length 
  

   of 
  the 
  central 
  fillet. 
  The 
  dorsal 
  rosy 
  stripe 
  is 
  narrower 
  iti 
  this 
  

   species 
  than 
  in 
  incerta. 
  The 
  character 
  of 
  the 
  inner 
  and 
  outer 
  cone, 
  

   also 
  of 
  the 
  spine, 
  is 
  similar 
  to 
  that 
  of 
  -S. 
  incerta. 
  

  

  Largest 
  specimen,

  perfect, 
  would 
  measure 
  130

  The 
  name 
  S. 
  sinope 
  was 
  substituted 
  by 
  Gray 
  for 
  the 
  S. 
  australis, 
  

   Q. 
  & 
  G. 
  {non 
  d'Orb.), 
  and 
  he 
  quoted 
  a 
  single 
  imperfect 
  shell 
  in 
  the 
  

   British 
  Museum 
  collection 
  which 
  was 
  labelled 
  " 
  China 
  ". 
  No 
  

   information 
  concerning 
  its 
  acquirement 
  is 
  attached 
  to 
  the 
  specimen, 
  

   and 
  consequently 
  in 
  all 
  probability 
  the 
  locality 
  cannot 
  be 
  relied 
  upon. 
  

   It 
  certainly 
  belongs 
  to 
  the 
  present 
  species. 
  

  

  This 
  is 
  one 
  of 
  the 
  smallest 
  South 
  African 
  forms, 
  and 
  the 
  shell 
  is 
  

   not 
  likely 
  to 
  be 
  confounded 
  with 
  that 
  of 
  any 
  other 
  species. 
  It 
  

   is 
  very 
  flat, 
  very 
  acuminate 
  posteriorly, 
  gradually 
  widening 
  towards 
  

   the 
  middle 
  and 
  then 
  gently 
  narrowing 
  towards 
  the 
  rounded 
  anterior 
  

   end. 
  The 
  ventral 
  side 
  exhibits 
  a 
  conspicuous 
  central 
  groove 
  which 
  

   broadens 
  in 
  front. 
  There 
  is 
  also 
  a 
  depression 
  on 
  each 
  side 
  near 
  the 
  

   lateral 
  margins, 
  so 
  that 
  the 
  surfaces 
  may 
  be 
  said 
  to 
  exhibit 
  three 
  

   furrows, 
  one 
  central 
  and 
  two 
  lateral. 
  The 
  dorsal 
  surface 
  has 
  

   a 
  distinct 
  central 
  cretaceous 
  ridge 
  marked 
  off 
  by 
  a 
  shallow 
  depression 
  

   on 
  each 
  side. 
  The 
  surface 
  is 
  then 
  smooth 
  and 
  somewhat 
  glossy, 
  

   except 
  towards 
  the 
  lateral 
  margins, 
  which 
  appear 
  to 
  have 
  a 
  yellowish 
  

   epidermal 
  covering. 
  The 
  smooth 
  areas 
  and 
  the 
  lateral 
  portions 
  of 
  

   the 
  surface 
  exhibit 
  delicate 
  yet 
  distinct 
  lines 
  of 
  growth. 
  A 
  remark- 
  

   able 
  characteristic 
  feature, 
  not 
  noticed 
  in 
  any 
  of 
  the 
  descriptions,
