  An 
  interesting 
  shell, 
  with 
  caudate, 
  narrow, 
  upper 
  and 
  apical 
  whorls. 
  

   The 
  type 
  is 
  Japanese. 
  It 
  has 
  lately 
  been 
  discovered 
  off 
  Australian 
  

   coasts

  refigured

  of 
  which 
  I 
  have 
  specimens 
  collected 
  during 
  

   the 
  " 
  Porcupine 
  " 
  Expedition. 
  It 
  differs, 
  however, 
  both 
  in 
  form 
  and 
  

   texture, 
  and 
  likewise 
  in 
  the 
  double 
  spiral 
  zone 
  on 
  the 
  last 
  whorl, 
  there 
  

   being, 
  as 
  the

  imply, 
  only 
  one

  A 
  curiously 
  formed 
  little 
  species, 
  with 
  contour 
  somewhat 
  resembling, 
  

   amongst 
  its 
  congeners, 
  E. 
  simplex, 
  Orbigny, 
  or 
  J^. 
  laxa, 
  Watson. 
  

   Under 
  a 
  lens 
  it 
  is 
  seen 
  to 
  be 
  very 
  finely 
  microscopically 
  striate. 
  

   I 
  expect 
  that 
  a 
  separate 
  genus 
  will 
  be 
  found 
  for 
  this, 
  and 
  perhaps 
  

   E. 
  cecea 
  in 
  the 
  course 
  of 
  time, 
  as 
  they 
  differ 
  in 
  so 
  many 
  particulars 
  

   from 
  the 
  typical 
  species 
  of 
  the 
  genus, 
  of 
  which 
  the 
  next 
  (^Kaisensis) 
  is 
  

   a 
  good 
  exponent.
