  Montagua 
  and 
  Mulleria 
  (p. 
  436). 
  All 
  these 
  three 
  were 
  later 
  intro- 
  

   duced 
  for 
  molluscs, 
  the 
  first 
  and 
  last 
  still 
  being 
  used, 
  the 
  second 
  one 
  

   rejected 
  on 
  different 
  grounds. 
  

  

  The 
  first-named 
  has 
  been 
  constantly 
  used 
  since 
  1882, 
  and 
  has 
  no 
  

   valid 
  synonymy, 
  so 
  I 
  name 
  the 
  penus 
  Syntagma, 
  the 
  ^yieci^s 
  Buccmum 
  

   Irunneuni, 
  Donovan, 
  being 
  retained 
  as 
  type. 
  The 
  genus 
  is 
  included 
  

   by 
  Dall 
  in 
  his 
  list 
  of 
  Turritidae, 
  without 
  comment, 
  though 
  years 
  ago 
  

   M. 
  Woodward 
  showed 
  that 
  the 
  radula 
  was 
  buccinoid. 
  

  

  AcosT^A, 
  Orbigny, 
  will 
  replace 
  Mulleria, 
  Ferussac, 
  1823. 
  

   As 
  above 
  noted 
  Ilulleria 
  can 
  no 
  longer 
  be 
  used 
  for 
  the 
  well-known 
  

   fresliwater 
  Oyster, 
  but 
  there 
  is 
  a 
  ready-made 
  alternative, 
  Acostcea, 
  

   Orbigny, 
  1851 
  (Rev. 
  & 
  Mag. 
  Zool., 
  ser. 
  II, 
  torn,

  p. 
  184), 
  available 
  

   for 
  use. 
  

  

  Gistkl's 
  Molluscan 
  Generic 
  Names, 
  1848. 
  

   In 
  a 
  book 
  entitled 
  " 
  N"aturgeschichte 
  des 
  Thierreichs 
  fiir 
  Schulen 
  ", 
  

   published 
  in 
  1848, 
  Gistel 
  introduced 
  a 
  large 
  number 
  of 
  corrections 
  (?) 
  

   of 
  invalid 
  names, 
  and 
  these 
  escaped 
  note 
  for 
  some 
  time, 
  probably 
  

   through 
  carelessness, 
  as 
  H. 
  & 
  A. 
  Adams 
  cited 
  many 
  of 
  them 
  in 
  their 
  

   "Genera 
  of 
  llecent 
  Mollusca". 
  The 
  names 
  are 
  recorded 
  in 
  "two 
  

   places 
  : 
  firstly, 
  in 
  a 
  prefatory 
  discussion 
  on 
  preoccupied 
  names, 
  and 
  

   secondly, 
  in 
  the 
  body 
  of 
  the 
  work. 
  The 
  former 
  list 
  was 
  obviously 
  

   compiled 
  as 
  an 
  after- 
  thought, 
  and 
  frequently 
  Gistel 
  has 
  named 
  the 
  same 
  

   thing 
  twice, 
  and 
  just 
  as 
  often 
  used 
  the 
  same 
  name 
  twice 
  in 
  different 
  

   connexions, 
  while 
  he 
  very 
  commonly 
  selected 
  preoccupied 
  names 
  in 
  

   his 
  corrections. 
  Since 
  the 
  book 
  is 
  not 
  well 
  known 
  and 
  the 
  names 
  

   may 
  need 
  consideration, 
  I 
  give 
  a 
  list 
  of 
  the 
  Gistel
