  three 
  lamellae 
  on 
  the

  the 
  middle 
  one 
  is 
  the 
  

   largest

  broadest, 
  a 
  strong 
  revolving 
  lamella 
  at 
  the 
  base 
  of 
  the 
  

   columella, 
  and 
  above 
  this, 
  and 
  situate 
  well 
  within 
  the 
  shell, 
  a 
  squarish, 
  

   shelf-like 
  projection,

  A 
  remarkable 
  shell 
  of 
  which 
  three 
  specimens 
  were 
  collected. 
  These 
  

   vary 
  in 
  size, 
  the 
  largest 
  being 
  13, 
  whilst 
  the 
  smallest 
  is 
  only 
  

   11 
  '25 
  mm. 
  in 
  length. 
  

  

  Two 
  of 
  the 
  specimens, 
  though 
  quite 
  fresh-looking, 
  appear 
  to 
  have 
  

   been 
  neatly 
  bored, 
  on 
  one 
  of 
  the 
  earlier 
  whorls, 
  by 
  some 
  enemy, 
  

   the 
  hole, 
  though 
  small, 
  being 
  in 
  each 
  case 
  very 
  similar 
  to 
  the 
  circular 
  

   holes 
  caused 
  by 
  the 
  depredations 
  of 
  Nassa 
  on 
  other 
  marine 
  species.

  nodulous 
  basal
