  I'KOCEHDINGS 
  OF 
  THU 
  MALACOLOGICAL 
  SOCIKTIT. 
  

  

  in 
  consequence 
  of 
  the 
  mistake 
  made 
  by 
  Dr. 
  Dall 
  with 
  regard 
  to 
  the 
  

   proper 
  type 
  of 
  Paphia 
  (Bolten). 
  

  

  The 
  selection 
  should 
  be 
  made 
  by 
  the 
  elimination 
  of 
  species 
  according 
  

   to 
  the 
  date 
  of 
  the 
  genera 
  to 
  which 
  they 
  belong. 
  If 
  Dr. 
  Dall's 
  

   application 
  of 
  the 
  name 
  Paphia 
  were 
  allowed 
  to 
  stand, 
  the 
  relative 
  

   ages 
  of 
  the 
  genera 
  concerned 
  would 
  be 
  in 
  the 
  following 
  order: 
  

   Bonax 
  (Linnaeus, 
  1758), 
  Paphia 
  (Bolten, 
  1798), 
  Venenipis 
  (Lamarck, 
  

   1799). 
  If, 
  however, 
  the 
  I'aphia 
  of 
  Bolten 
  was 
  wrongly 
  determined 
  

   by 
  Dall, 
  and 
  should 
  not 
  be 
  applied 
  to 
  the 
  Tapes 
  group, 
  then 
  the 
  order 
  

   of 
  the 
  genera 
  concerned 
  would 
  be 
  Donax 
  (Linn.), 
  Venerupis 
  (Lam.), 
  

   and 
  Tapes 
  (Megerle, 
  1811), 
  Avith 
  the 
  result 
  that 
  Tapes 
  would 
  be 
  

   replaced 
  by 
  Ciineus. 
  

  

  Under 
  these 
  circumstances 
  it 
  seems 
  best 
  not 
  to 
  make 
  any 
  definite 
  

   selection 
  of 
  a 
  type 
  for 
  Cuneus 
  until 
  the 
  doubt 
  about 
  the 
  proper 
  choice 
  

   of 
  a 
  type 
  for 
  Paphia 
  has 
  been 
  decided. 
  Meantime 
  it 
  is 
  clear 
  that 
  the 
  

   rules 
  of 
  the 
  Commission 
  do 
  not 
  yet 
  afford 
  suflScient 
  guidance 
  for 
  the 
  

   proper 
  selection 
  of 
  types, 
  and 
  that 
  it 
  is 
  premature 
  to 
  enact 
  that 
  any 
  

   selection 
  should 
  be 
  absolutely 
  unalterable. 
  There 
  should, 
  at 
  least, 
  be 
  

   the 
  possibility 
  of 
  an 
  appeal 
  to 
  the 
  Commission 
  itself. 
  

  

  Postscript. 
  Since 
  the 
  above 
  was 
  written 
  Dr. 
  Hoyle 
  has 
  announced 
  

   that 
  a 
  proposal 
  has 
  been 
  submitted 
  to 
  the 
  International 
  Commission 
  

   on 
  Zoological 
  Nomenclature 
  that 
  a 
  certain 
  number 
  of 
  commonly 
  used 
  

   generic 
  names 
  should 
  be 
  excepted 
  from 
  the 
  application 
  of 
  the 
  Law 
  of 
  

   Priorit}', 
  and 
  that 
  an 
  Official 
  List 
  of 
  these 
  names 
  should 
  be 
  published. 
  

   Such 
  a 
  plan 
  would 
  solve 
  many 
  difficulties, 
  and 
  should 
  have 
  the 
  

   approval 
  of 
  a 
  majority 
  of 
  the 
  members 
  of 
  our 
  Society, 
  as 
  it 
  has 
  of 
  the 
  

   Zoological 
  Society. 
  It 
  appears 
  to 
  be 
  the 
  only 
  legitimate 
  way 
  in 
  which 
  

   Conchologists 
  can 
  avoid 
  having 
  a 
  large 
  number 
  of 
  the 
  familiar 
  

   Lamarckian 
  names 
  displaced 
  by 
  the 
  unfamiliar 
  and 
  often 
  imcouth 
  

   names 
  of 
  Bolten. 
  It 
  will 
  solve 
  all 
  the 
  difficulties 
  raised 
  in 
  this 
  paper 
  

   if 
  it 
  be 
  simply 
  enacted 
  that 
  the 
  genera 
  Corlis 
  and 
  Pectiinculus 
  of 
  

   Lamarck 
  and 
  Tapes 
  of 
  Megerle 
  are 
  exempted 
  from 
  change 
  ; 
  and 
  if 
  

   Callista 
  (Morch 
  after 
  Poll), 
  witli 
  C. 
  chione 
  as 
  type, 
  finds 
  a 
  place 
  in 
  the 
  

   official 
  list 
  there 
  need 
  be 
  no 
  more 
  trouble 
  about 
  the 
  proper 
  type 
  of 
  

   Paphia 
  or 
  about 
  the 
  prior 
  claim 
  of 
  Callista 
  (Leach).
