  also 
  occurring

  The

  however, 
  free

  A 
  small

  white, 
  plain 
  species, 
  very 
  smooth, 
  some 
  differences 
  

   of 
  form 
  existing, 
  and 
  perhaps 
  two 
  species 
  may 
  be 
  confused 
  together. 
  

   More 
  material 
  is 
  wanted, 
  however, 
  before 
  this 
  can 
  be 
  truly 
  discerned.

  A 
  well-marked

  at 
  first 
  thought 
  by 
  malacologists 
  to 
  be 
  

   a 
  possible 
  monstrosity,

  many 
  examples,
