  I 
  have 
  not 
  quoted 
  Weinkauff 
  in 
  the 
  above 
  synonymy, 
  as 
  I 
  do 
  not 
  

   feel 
  sure 
  that 
  the 
  shell 
  figured 
  by 
  him 
  (pi. 
  xxvi, 
  figs. 
  3, 
  4) 
  belongs 
  to 
  

   this 
  species. 
  It 
  is 
  said 
  to 
  be 
  5 
  mm. 
  in 
  length, 
  whereas 
  the 
  largest 
  

   example 
  I 
  have 
  seen 
  is 
  only 
  4 
  ram. 
  E. 
  pellucida, 
  Reeve, 
  is 
  absolutely 
  

   the 
  same 
  as 
  the 
  present 
  species. 
  The 
  labral 
  teeth 
  are 
  fine 
  and 
  

   numerous, 
  about 
  twenty-three 
  in 
  number.

  The 
  following 
  species 
  described 
  or 
  placed 
  in

  do 
  not 
  belong 
  to

  The 
  description 
  of 
  the 
  ' 
  ' 
  columellar 
  lip 
  with 
  three 
  folds 
  anteriorly 
  ' 
  ' 
  

   and 
  of 
  the 
  outer 
  lip, 
  " 
  very 
  minutely 
  and 
  indistinctly 
  toothed 
  along 
  its 
  

   inner 
  margin," 
  together 
  with 
  the 
  figure, 
  shows 
  that 
  this 
  species 
  is 
  

   identical 
  with 
  Marginella 
  triplicata 
  of 
  Gaskoin. 
  The 
  E. 
  guttata 
  [sic] 
  

   of 
  Sowerby 
  {b) 
  and 
  Reeve 
  [b) 
  was 
  founded 
  on 
  worn 
  examples 
  of 
  the 
  

   var. 
  callosa 
  of 
  E. 
  lachryma. 
  Tryon, 
  under 
  E. 
  guttula, 
  reproduced 
  

   Sowerby's 
  figures 
  of 
  guttata, 
  being 
  under 
  the 
  impression 
  that 
  they 
  

   represented 
  the 
  true 
  guttula. 
  Weinkauff 
  noticed 
  this 
  species 
  was 
  

   a 
  Marginella.

  Tryon 
  (p. 
  10) 
  considered 
  this 
  species 
  "probably 
  identical" 
  with 
  

   E. 
  Maugerce. 
  A 
  reference 
  to 
  the 
  dimensions 
  given 
  by 
  Adams 
  shows, 
  

   however, 
  that 
  it 
  was 
  a 
  much 
  larger 
  shell 
  he 
  had 
  before 
  him, 
  and 
  

   I 
  have 
  no 
  doubt 
  that 
  his 
  species 
  is 
  the 
  same 
  as 
  Pachybathron 
  

   marginelloideum 
  of 
  Gaskoin. 
  Adams's 
  specimens 
  appear 
  to 
  have 
  been 
  

   worn 
  and 
  faded 
  and 
  to 
  have 
  lost 
  the 
  markings, 
  excepting 
  the 
  brown 
  

   stain 
  below 
  the 
  suture 
  described 
  both 
  by 
  him 
  and 
  Gaskoin.
