  Beyond 
  a 
  difference 
  in 
  size 
  it 
  is 
  difficult 
  to 
  find 
  any 
  distinguishing 
  

   features 
  between 
  this 
  species 
  and 
  the 
  AVest 
  Indian 
  E. 
  Maugerm. 
  It 
  

   is 
  subject 
  to 
  great 
  variation 
  in 
  size, 
  and 
  among 
  a 
  number 
  of 
  

   specimens 
  from 
  Salcomb 
  Bay, 
  Devon, 
  I 
  find 
  the 
  largest 
  to 
  be 
  10 
  mm. 
  

   in 
  length, 
  whereas 
  the 
  smallest 
  is 
  only 
  6. 
  E. 
  Maugerce 
  is 
  perhaps 
  

   more 
  shortly 
  pyriform, 
  and 
  at 
  the 
  upper 
  part 
  of 
  the 
  columella 
  

   a 
  small 
  tubercle 
  is 
  generally 
  observable, 
  which 
  does 
  not 
  occur, 
  or 
  

   is 
  less 
  noticeable, 
  in 
  E. 
  Icsvis. 
  The 
  shells 
  described 
  by 
  Carpenter 
  as 
  

   E. 
  Manger 
  im 
  (?), 
  var. 
  Panamensis, 
  figured 
  by 
  Peeve 
  as 
  Maugerics, 
  might 
  

   with 
  equal 
  propriety 
  be 
  regarded 
  as 
  a 
  variety 
  of 
  the 
  present 
  species, 
  

   which 
  tbey 
  resemble 
  so 
  closely 
  that 
  one 
  only 
  hesitates 
  to 
  name 
  

   them 
  E. 
  Icevts 
  because 
  of 
  the 
  locality 
  from 
  which 
  they 
  are 
  said 
  to 
  

   have 
  come. 
  One 
  of 
  the 
  three 
  shells 
  described 
  by 
  Carpenter 
  has 
  

   been 
  figured 
  by 
  Sowerby 
  as 
  a 
  E. 
  suleifera, 
  Gray, 
  a 
  much 
  smaller 
  

   granose 
  shell 
  which 
  occurs 
  at 
  the 
  Mauritius 
  and 
  elsewhere 
  in 
  the 
  

   East. 
  Peeve 
  also 
  has 
  figured 
  a 
  small 
  example 
  of 
  E. 
  Icevis 
  as 
  

   E. 
  callosa, 
  Ad. 
  & 
  Peeve, 
  which 
  is 
  easily 
  separated 
  by 
  the 
  narrower 
  

   aperture, 
  excavated 
  columella, 
  and 
  more 
  finely 
  denticulated 
  labrum.

  Never 
  so 
  large 
  as 
  E. 
  Icevis, 
  otherwise 
  very 
  similar. 
  It 
  is 
  sometimes 
  

   pale

  colour, 
  or 
  it 
  may 
  be 
  olivaceous.

  I 
  do 
  not 
  find 
  anything 
  in 
  the 
  brief 
  description 
  of 
  this 
  species 
  

   to 
  distinguish 
  it 
  from 
  the

  E. 
  Maugerce.
