  that 
  this 
  was 
  " 
  probably 
  a 
  minute 
  foreign 
  MnrgineUa 
  ". 
  

   It 
  was 
  iu 
  his 
  Supplement, 
  too, 
  p. 
  100, 
  pi. 
  xxx, 
  fig. 
  2, 
  that 
  Montagu 
  

   established 
  the 
  Voluta 
  bidentata, 
  which 
  is 
  one 
  of 
  the 
  two 
  species 
  

   umler 
  present 
  discussion. 
  

  

  According 
  to 
  Moquiu-Tandon, 
  iwrmn 
  [Helvetincher 
  Alnumach, 
  1817, 
  

   p. 
  34) 
  included 
  under 
  the 
  name 
  Auricella, 
  an 
  A. 
  myosotis 
  and 
  

   A. 
  lineata. 
  The 
  authors 
  of 
  the 
  species 
  are 
  not 
  given 
  by 
  Moquin- 
  

   Tandon, 
  but 
  if, 
  as 
  seems 
  to 
  be 
  inferred 
  from 
  his 
  citations, 
  they 
  were 
  

   Draparnaud's 
  species, 
  the 
  association 
  of 
  two 
  such 
  diverse 
  animals 
  

   without 
  indication 
  of 
  a 
  type 
  renders 
  the 
  name 
  useless, 
  and 
  it 
  may 
  be 
  

   safely 
  disregarded, 
  even 
  though 
  Moquin-Tandon 
  adopts 
  it 
  as 
  a 
  

   sectional 
  name 
  fur 
  the 
  latter 
  of 
  the 
  two. 
  

  

  In 
  1819 
  Turton, 
  in 
  his 
  Conchological 
  Dictionary 
  (p. 
  250), 
  quite 
  

   oblivious 
  of 
  his 
  Valuta 
  alba 
  in 
  the 
  General 
  System 
  of 
  Nature 
  cited 
  

   above, 
  described 
  under 
  the 
  same 
  name 
  a 
  shell 
  manifestly 
  identical 
  

   with 
  Montagu's 
  V. 
  bidentata. 
  

  

  Leach, 
  the 
  same 
  year, 
  in 
  the 
  proofs 
  of 
  his 
  Molluscorum 
  Britannice 
  

   Synopsis, 
  proposes 
  laminia 
  (p. 
  134) 
  for 
  bidentata 
  and 
  Alexia 
  (p. 
  135) 
  

   for 
  denticulata. 
  The 
  Voluta 
  alba 
  does 
  not 
  seem 
  to 
  have 
  received 
  his 
  

   attention. 
  

  

  Grayiu 
  1821 
  {London 
  Medical 
  Repository, 
  xv, 
  p. 
  231) 
  used 
  Phytia 
  

   (probably 
  a 
  misspelling 
  for 
  Pythia 
  which 
  lie 
  adopts 
  in 
  1847) 
  for 
  

   V. 
  denticulata 
  ; 
  whilst 
  in 
  1825 
  {Annals 
  of 
  Philosophy, 
  xxv, 
  p. 
  415) 
  he 
  

   refers 
  bidentata 
  and 
  alba, 
  both 
  of 
  Montagu, 
  to 
  Auricula. 
  

  

  Brown 
  in 
  1827 
  {Illustrations 
  of 
  the 
  Conchologij 
  of 
  Great 
  Britain 
  and 
  

   Ireland, 
  Ist 
  ed., 
  p. 
  iv) 
  used 
  Leach's 
  name 
  Jaminia 
  (which 
  he 
  wrong- 
  

   fully 
  attributed 
  to 
  Bruguiere, 
  who 
  never 
  employed 
  it) 
  for 
  a 
  group 
  in 
  

   Avhich 
  the 
  molluscs 
  in 
  question 
  were 
  included. 
  

  

  Fleming 
  in 
  1828 
  {History 
  of 
  British 
  Animals, 
  p. 
  333) 
  referred 
  

   " 
  r. 
  alba, 
  Mont., 
  Test. 
  Brit., 
  235. 
  Turton's 
  Cotich. 
  Diet. 
  250" 
  

   (thus 
  mixing 
  two 
  distinct 
  forms) 
  to 
  Lamarck's 
  Volcaria, 
  whilst 
  

   putting 
  under 
  Acteon 
  the 
  denticulatus 
  and 
  bidcntntus 
  of 
  Montagu. 
  

  

  Jeffreys 
  followed 
  Fleming 
  as 
  to 
  alba 
  in 
  1830 
  {2rans. 
  Linn. 
  Soc. 
  

   Land., 
  xvi, 
  p. 
  369), 
  but 
  put 
  a 
  "?" 
  to 
  tlie 
  reference 
  to 
  Montagu 
  

   and 
  placed 
  the 
  species 
  under 
  "Auricula, 
  Drap." 
  

  

  Bivona 
  Beruardi 
  in 
  1832 
  {Effemeridi 
  scientifiche 
  e 
  letteraire 
  per 
  la 
  

   Sicilia, 
  i, 
  p. 
  58) 
  founded 
  the 
  genus 
  Ovatella 
  for 
  0. 
  punctata 
  (whicli 
  is 
  

   akin 
  to 
  our 
  denticulata) 
  and 
  another 
  species 
  belonging 
  to 
  quite 
  another 
  

   type 
  of 
  shell; 
  whilst 
  a 
  little 
  later 
  (op. 
  cit., 
  ii, 
  p. 
  18) 
  he 
  adds 
  an 
  

   0. 
  bidentata, 
  which 
  is 
  distinct 
  from 
  the 
  British 
  species 
  of 
  that 
  name 
  

   and 
  which 
  was 
  renamed 
  bivonce 
  by 
  Pliilippi 
  {Enumeratio 
  Molluscorum 
  

   Sicili<B, 
  ii, 
  1844, 
  p, 
  118). 
  We 
  have 
  been 
  indebted, 
  and 
  hereby 
  

   return 
  our 
  grateful 
  thanks, 
  to 
  the 
  Marcliese 
  di 
  Monterosato 
  for 
  the 
  

   opportunity 
  of 
  examining 
  these 
  species 
  of 
  Bivona 
  with 
  other 
  

   Mediterranean 
  forms. 
  

  

  In 
  1840 
  Gray 
  (Turton's 
  Manual, 
  new 
  edition, 
  pp. 
  224-228) 
  put 
  

   tiie 
  three 
  species 
  under 
  Conorulus, 
  which 
  he 
  divided 
  into 
  Ovatella 
  

   (Bivona) 
  for 
  C. 
  denticulatus 
  and 
  a 
  new 
  section 
  Leuconia 
  for 
  

   C. 
  bidentatus 
  and 
  albus. 
  

  

  This 
  he 
  changed 
  in 
  1847 
  {Proc. 
  Zool. 
  Soc. 
  Land., 
  xv, 
  p. 
  179).
