  PROCHEDINGS

  THE

  SOCIETY. 
  

  

  the 
  word 
  ' 
  pleurotomarius' 
  appears 
  and 
  j). 
  166 
  is 
  added. 
  From 
  

   Dumeril's 
  usage 
  it 
  can 
  be 
  deduced 
  that 
  these 
  are 
  connected, 
  but 
  

   strictly 
  speaking 
  I 
  would 
  have 
  regarded 
  the 
  index 
  names 
  as 
  noinina 
  

   niida, 
  and 
  objected 
  to 
  their 
  active 
  incorporation 
  into 
  molluscan 
  

   nomenclature. 
  Three 
  bibliographical 
  references 
  are 
  given 
  by 
  Diimeril 
  

   — 
  first 
  to 
  Cuvier's 
  TahleaicElem., 
  second 
  to 
  Toli, 
  and 
  third 
  to 
  Lamarck. 
  

   Consequently 
  Dumeril's 
  names 
  all 
  depend 
  on 
  these 
  works. 
  I 
  therefore 
  

   allot 
  all 
  I 
  can 
  first 
  to 
  Cuvier's 
  work, 
  then 
  to 
  Poli's, 
  and 
  lastly 
  to 
  

   Lamarck's 
  as 
  synonyms. 
  Cuvier's 
  names 
  are 
  simply 
  those 
  of 
  Linne, 
  

   so 
  that 
  Dumeril's 
  names 
  follow 
  the 
  Liiinean 
  ones 
  and 
  are 
  absolute 
  

   synonyms 
  of 
  those. 
  None 
  are 
  referable 
  as 
  new 
  to 
  Poli, 
  so 
  that 
  the 
  

   only 
  names 
  that 
  interest 
  us 
  are 
  the 
  emendations 
  of 
  the 
  Lamarckian 
  

   names. 
  ]\[ost 
  interest 
  centres 
  around 
  

  

  Nassarius. 
  

  

  This 
  can 
  only 
  be 
  determined 
  as 
  a 
  new 
  name 
  for 
  Nassa, 
  Lamarck, 
  

   1799, 
  non 
  Bolten, 
  1798. 
  The 
  type 
  of 
  Nassa, 
  Lam., 
  is 
  Buccinum 
  

   mutabile, 
  Linn. 
  Recently 
  Lamarck's 
  familiar 
  name 
  has 
  been 
  

   rejected, 
  as 
  it 
  was 
  antedated 
  by 
  Bolten's 
  usage 
  in 
  another 
  con- 
  

   nexion. 
  As 
  substitutes 
  Arcularia, 
  Link, 
  1807, 
  and 
  Alectrion, 
  

   ^lontfort, 
  1810, 
  have 
  been 
  utilized. 
  I 
  have 
  argued 
  for 
  the 
  adoption 
  

   of 
  both 
  as 
  distinct 
  genera, 
  but 
  this 
  proposal 
  was 
  due 
  to 
  a 
  mis- 
  

   conception 
  of 
  the 
  types 
  of 
  the 
  two 
  genera, 
  and 
  I 
  now 
  withdraw 
  

   that 
  view, 
  and 
  would 
  accept 
  J^assarius 
  as 
  a 
  substitute 
  for 
  Lamarck's 
  

   Nassa^ 
  and 
  use 
  it 
  in 
  place 
  of 
  either 
  Arcularia 
  or 
  Alectrion} 
  The 
  

   family 
  name 
  would 
  be 
  Nassariidse, 
  and 
  this 
  would 
  recall 
  the 
  defunct 
  

   Nassidaj. 
  With 
  regard 
  to 
  Link's 
  Nassaria 
  I 
  unhesitatingly 
  reject 
  

   it 
  on 
  account 
  of 
  the 
  previous 
  Nassarius 
  of 
  Dumeril, 
  and 
  think 
  the 
  

   change 
  should 
  be 
  welcomed 
  since 
  tlie 
  name 
  to 
  be 
  used 
  is 
  

  

  HiNDSFA, 
  H. 
  & 
  A. 
  Adams, 
  1850. 
  

  

  and 
  the 
  conchologist 
  thus 
  honoured 
  stands 
  in 
  such 
  repute 
  that 
  his 
  

   dedicatory 
  genus 
  must 
  please 
  his 
  successors 
  in 
  the 
  study. 
  Further, 
  

   Link's 
  name 
  seems 
  to 
  have 
  siniply 
  been 
  an 
  amendment 
  of 
  Nassa, 
  and 
  

   in 
  the 
  case 
  of 
  Link's 
  Nucidana 
  this 
  was 
  urged 
  as 
  a 
  valid 
  cause 
  for 
  

   rejection 
  by 
  Dr. 
  Dall 
  himself. 
  I 
  do 
  not 
  accept 
  this 
  view, 
  but 
  even 
  

   the 
  constituents 
  of 
  Link's 
  genus 
  are 
  varied, 
  and 
  it 
  should 
  never 
  have 
  

   been 
  utilized 
  to 
  dispossess 
  Hindsia. 
  Again, 
  Eafinesque 
  later 
  proposed 
  

   Nassaria 
  as 
  a 
  new 
  name 
  for 
  Nassa, 
  Lam., 
  which 
  suggests 
  the 
  same 
  

   idea 
  ran 
  through 
  all 
  these 
  workers' 
  minds 
  

  

  Ttie 
  rejection 
  of 
  Pleurotomaria 
  in 
  view 
  of 
  Dvi\nev\Vs 
  Pleurotoviarius 
  

   does 
  not 
  seem 
  to 
  be 
  a 
  cause 
  for 
  much 
  sentiment. 
  It 
  is 
  somewhat 
  

   obvious 
  that 
  the 
  name 
  as 
  commonly 
  used 
  would 
  become 
  restricted 
  

   until 
  it 
  was 
  almost 
  lost. 
  The 
  recent 
  species 
  have 
  already' 
  been 
  

   subdivided 
  from 
  a 
  study 
  of 
  anatomical 
  characters, 
  so 
  that 
  the 
  " 
  genus 
  

   Pleurotomaria^^ 
  raay 
  be 
  considered 
  to 
  represent 
  -a 
  family. 
  That 
  

   " 
  Pleurotomaria 
  " 
  now 
  is 
  the 
  distinctive 
  term 
  for 
  a 
  (heterogeneous) 
  

  

  ^ 
  With 
  the 
  proviso 
  that 
  later 
  investigation 
  of 
  the 
  animals 
  of 
  the 
  types 
  of 
  these 
  

   two 
  genera 
  may 
  cause 
  separation.
