  In 
  the 
  original 
  description 
  there 
  is 
  no 
  mention 
  of 
  any 
  plaits 
  in 
  the 
  

   mouth, 
  though 
  the 
  figure 
  shows 
  two 
  on 
  the 
  parietal 
  whorl. 
  In 
  the 
  

   collection 
  in 
  the 
  Paris 
  Museum 
  the 
  specimens 
  so 
  named 
  undoubtedly 
  

   belong 
  to 
  L. 
  Ueynemanni, 
  but 
  as 
  they 
  also 
  have 
  specimens 
  named 
  

   L. 
  turricula 
  referable 
  to 
  the 
  same 
  species 
  the 
  evidence 
  is 
  not 
  

   important.

  excavata, 
  copied

   Tr3-on 
  to 
  illustrate 
  L. 
  Jacquinoti, 
  apparently 
  represent 
  a 
  young 
  shell 
  

   ■which 
  seems 
  to 
  agree 
  better 
  with 
  L. 
  Ueynemanni 
  in 
  general 
  characters 
  

   tlian 
  with 
  either 
  of 
  the 
  other 
  two 
  species 
  to 
  which 
  it 
  has 
  been 
  at 
  times 
  

   assigned.
