  a

  species 
  attached 
  

   and 
  the 
  parts

  issued 
  pari 
  passu 
  with 
  those 
  of 
  the 
  same 
  

   author's 
  Concliologica 
  Iconica, 
  it 
  is 
  possible 
  that 
  a 
  thorough 
  search 
  

   through 
  the 
  nomenclature 
  may 
  lead 
  to 
  some 
  revisions. 
  Amongst 
  the 
  

   genera 
  dealt 
  with 
  the 
  following 
  are 
  suggested 
  as 
  requiring 
  investi- 
  

   gation, 
  viz. 
  Cymiiuvi, 
  Ricinula, 
  Typhis, 
  Pyrula, 
  Mangelia, 
  Fastigiella, 
  

   Cerithiiim, 
  and 
  Monoptygma.
