  After 
  carefully 
  studying 
  the 
  shells 
  described 
  under 
  the 
  above 
  

   four 
  names 
  I 
  am 
  of 
  opinion 
  that 
  they 
  belong 
  to 
  a 
  single 
  species. 
  

   They 
  are 
  all 
  more 
  or 
  less 
  granular, 
  with 
  a 
  dorsal 
  groove, 
  which, 
  

   however, 
  is 
  absent 
  in 
  some 
  smooth 
  or 
  only 
  partly 
  granose 
  varieties. 
  

   All 
  are 
  red-tipped 
  anteriorly, 
  and 
  the 
  character 
  of 
  the 
  labraland 
  

   columellar 
  dentation 
  is 
  quite 
  the 
  same, 
  although 
  the 
  actual 
  number 
  of 
  

   teeth 
  may 
  vary 
  somewhat 
  according 
  to 
  the 
  length 
  of 
  the 
  labrum, 
  the 
  

   larger 
  specimens 
  having 
  more 
  than 
  the 
  smaller 
  ones. 
  Some 
  examples 
  

   from 
  Mauritius 
  are 
  peculiar 
  in 
  the 
  absence 
  of 
  a 
  dorsal 
  sulcus, 
  and 
  

   in 
  being 
  much 
  smoother 
  than 
  typical 
  specimens. 
  There 
  are, 
  however, 
  

   scattered 
  minute 
  granules 
  upon 
  the 
  body-whorl, 
  and 
  the 
  spire 
  is 
  

   distinctly 
  granose. 
  'i'hej 
  offer 
  no 
  difference 
  in 
  form 
  or 
  colour. 
  Some 
  

   of 
  the 
  specimens 
  from 
  Port 
  Shepstone 
  belong 
  to 
  this 
  smooth 
  variety, 
  

   but 
  others 
  are 
  normally 
  granular. 
  The 
  ^. 
  sulcifera 
  of 
  Sowerby's 
  

   Thesaurus 
  is 
  a 
  combination 
  of 
  E. 
  lachryma, 
  var. 
  callosa, 
  and 
  the 
  

   var. 
  I'anamensis 
  of 
  E. 
  lavis. 
  Figs. 
  1, 
  2 
  represent 
  worn 
  and 
  dead 
  

   specimens 
  of 
  JE. 
  lachryma, 
  var. 
  callosa, 
  and 
  fig. 
  3 
  is, 
  as 
  stated 
  by 
  

   Sowerby, 
  the 
  var. 
  Panamensis 
  (of 
  Icevis). 
  The 
  dorsal 
  groove 
  indicated 
  

   in 
  the 
  figures 
  is 
  quite 
  imaginary, 
  as 
  in 
  the 
  specimens 
  in 
  the 
  Cuming 
  

   Collection 
  there 
  is 
  no 
  indication 
  of 
  it, 
  nor 
  is 
  it 
  shown 
  in 
  Reeve's 
  

   figure 
  (Conch. 
  Icon., 
  fig. 
  \Ah), 
  where 
  one 
  of 
  the 
  two 
  Cumingian 
  shells 
  

   lalDelled 
  sulcifera 
  is 
  depicted. 
  Weinkauff 
  (p.

   has 
  merely 
  copied 
  Reeve's 
  figures, 
  and 
  based 
  his 
  description 
  upon 
  them.

  This 
  specimen 
  is 
  well 
  characterized 
  by 
  its 
  triangular 
  pyriform 
  

   shape, 
  the 
  very 
  narrow 
  linear 
  aperture, 
  the 
  broad 
  thickened 
  labrum 
  

   with 
  the 
  lirse 
  extending 
  almost 
  across 
  it, 
  and 
  similar 
  lirse 
  across 
  the 
  

   end 
  of 
  the 
  body-whorl. 
  A 
  feature 
  overlooked 
  in 
  all 
  descriptions 
  is 
  

   the 
  presence 
  of 
  a 
  brown 
  spot 
  at 
  the 
  posterior 
  end 
  of 
  the 
  labrum 
  and 
  

   at 
  the 
  anterior 
  extremity 
  of 
  the 
  body- 
  whorl. 
  These 
  spots 
  are 
  present 
  

   in 
  nearly 
  all 
  fresh 
  specimens, 
  but 
  may 
  not 
  be 
  noticeable 
  in 
  dead 
  and 
  

   worn 
  shells. 
  E. 
  anguUfera, 
  founded 
  on 
  a 
  few 
  small 
  worn 
  specimens, 
  

   possesses 
  all 
  the 
  essential 
  features 
  of 
  gallinacea.
