﻿SMITH

  ON 
  THE 
  GKNUS 
  ERATO.

  Only 
  four 
  worn 
  specimens 
  have 
  been 
  examined. 
  In 
  this 
  condition 
  

   they 
  are 
  smooth, 
  and 
  do 
  not 
  show 
  any 
  signs 
  of 
  granulation. 
  It 
  is 
  of 
  

   narrow 
  form 
  like 
  typical 
  sulcifera, 
  and 
  like 
  that 
  species 
  has 
  a 
  very 
  

   narrow 
  aperture. 
  The 
  labral 
  denticles 
  are 
  close-set, 
  and 
  from 
  twenty- 
  

   two 
  to 
  twenty-four 
  in 
  number. 
  The 
  lower 
  or 
  anterior 
  end 
  of 
  the 
  

   columella 
  is 
  distinctly 
  denticulate, 
  but 
  further 
  up 
  the 
  denticles 
  become 
  

   very 
  minute, 
  and 
  gradually 
  obsolete 
  posteriorly. 
  The 
  colour 
  is 
  

   accurately 
  described 
  by 
  Pease, 
  but 
  Sowerby's 
  " 
  pallide 
  rosea" 
  is 
  

   purely 
  imaginary, 
  and 
  his 
  figure, 
  tinted 
  a 
  delicate 
  pink, 
  is 
  equally 
  

   misleading. 
  The 
  figure 
  given 
  by 
  lleeve 
  and 
  copied 
  by 
  Weinkauff 
  

   is 
  fairly 
  good. 
  It 
  is 
  very 
  closely 
  allied 
  to 
  E. 
  lachryma, 
  but 
  may 
  be 
  

   a 
  trifle 
  more 
  slender, 
  has 
  a 
  slightly 
  narrower 
  aperture, 
  and 
  the 
  rosy 
  

   tint 
  of 
  the 
  apex 
  and 
  anterior 
  extremity 
  is 
  peculiar.

  The 
  figure 
  above 
  quoted 
  is 
  not 
  of 
  much 
  use 
  beyond 
  giving 
  some 
  

   idea 
  of 
  the 
  general 
  form 
  of 
  the 
  species. 
  The 
  characteristic 
  rosy 
  spots 
  

   at 
  both 
  ends 
  are 
  very 
  striking, 
  and 
  at 
  once 
  distinguish 
  this 
  species 
  

   from 
  the 
  rest. 
  The 
  columella 
  is 
  said 
  by 
  Tate 
  to 
  have 
  " 
  eight 
  crowded 
  

   transverse 
  plaits". 
  It 
  may, 
  however, 
  be 
  crenulated 
  the 
  whole 
  length, 
  

   the 
  denticulation 
  at 
  and 
  above 
  the 
  middle 
  being 
  very 
  minute. 
  

   Within 
  this 
  the 
  whorl 
  is 
  broadly 
  and 
  deeply 
  excavated.
