  recent 
  and 
  fossil 
  shells 
  agree 
  well. 
  It 
  "will 
  cause 
  little 
  confusion 
  to 
  

   accept 
  this 
  name, 
  and 
  I 
  do 
  not 
  think 
  much 
  ohjection 
  can 
  be 
  urged 
  

   against 
  its 
  adoption. 
  It 
  is 
  certainly 
  more 
  appropriate 
  to 
  the 
  Peronii 
  

   shells 
  than 
  Liotia.

  Yers., 
  vol.

  1832, 
  after 
  p. 
  552 
  is

   a

  system 
  of 
  molluscs, 
  and 
  therein, 
  next 
  to 
  Planaxe, 
  is 
  included 
  

   Quoyie. 
  I^o 
  Latin 
  equivalents 
  are 
  given, 
  yet 
  it 
  would 
  appeur 
  that 
  

   this 
  has 
  been 
  quoted 
  by 
  some 
  writers, 
  e.g. 
  Tiyon, 
  as 
  the 
  introduction 
  

   of 
  Quoi/ia. 
  

  

  In 
  the 
  Zoology 
  of 
  Beechey's 
  Voyage, 
  1839, 
  Molluscous 
  Animals, 
  

   p. 
  125, 
  Gray 
  gave 
  a 
  description 
  of 
  the 
  genus 
  Quoyia, 
  neither 
  ascribing 
  

   it 
  to 
  anj^one 
  nor 
  claiming 
  it 
  as 
  new. 
  In 
  the 
  Proc. 
  Zool. 
  Soc. 
  

   Lond., 
  1847, 
  p. 
  138, 
  Gray 
  quoted 
  it 
  as 
  " 
  Quoyia, 
  Desh. 
  MSS., 
  

   1830 
  ; 
  Gray, 
  1839 
  ; 
  Planaxis 
  decollahis, 
  Quoy 
  and 
  Desh." 
  As 
  

   a 
  synonym 
  of 
  this 
  genus 
  is 
  given 
  Fissulahria, 
  T. 
  Brown, 
  Edin. 
  Jour. 
  

   Nat. 
  Hist., 
  1836. 
  It 
  was 
  this 
  entiy, 
  which 
  Mr. 
  C. 
  Davies 
  Sherborn 
  

   kindly 
  brought 
  to 
  my 
  notice, 
  that 
  caused 
  this 
  inquiry. 
  The 
  

   Edinburgh 
  Journal 
  of 
  J^atural 
  History 
  and 
  Physical 
  Sciences 
  has 
  

   upon 
  the 
  title-page 
  " 
  Conducted 
  by 
  William 
  Macgillivray 
  ", 
  and 
  as 
  

   the 
  article 
  in 
  question 
  is 
  unsigned 
  I 
  conclude 
  the 
  genus 
  should 
  be 
  

   credited 
  to 
  Macgillivray. 
  I 
  have 
  been 
  unable 
  to 
  trace 
  the 
  origin 
  of 
  its 
  

   reference 
  to 
  Brown 
  further 
  than 
  Gray, 
  as 
  above. 
  

  

  Macgillivray 
  called 
  the 
  genus 
  Fissilahia, 
  the 
  species 
  name 
  selected 
  

   being 
  fasciata 
  ; 
  three 
  fair 
  recognizable 
  features 
  are 
  given, 
  and 
  its 
  

   habitat 
  was 
  supposed 
  to 
  be 
  New 
  Holland. 
  Consequently 
  Fissilalia 
  

   must 
  displace 
  Quoyia, 
  but 
  the 
  species 
  name 
  will 
  remain 
  decoUata, 
  as 
  

   Quoy 
  and 
  Gaimard's 
  name 
  has 
  priority. 
  Thus 
  we 
  have 
  Fissilabia, 
  

   jNIacgillivray, 
  1836= 
  Quoyia, 
  Gray, 
  1839. 
  Type: 
  F. 
  fasciata, 
  

   Macgil. 
  = 
  Planaxis 
  decoUata, 
  Quoy 
  & 
  Gaimard, 
  1833 
  (Zool. 
  del'AstroL, 
  

   Zool., 
  vol. 
  ii, 
  p. 
  489). 
  

  

  Adeorbis. 
  

   Sacco 
  (I 
  Mollus. 
  Terr. 
  Terz. 
  Piemonte, 
  pt. 
  xxi, 
  p. 
  55, 
  1896) 
  has 
  

   pointed 
  out 
  that 
  Tornus, 
  Turton, 
  1829, 
  was 
  introduced 
  for 
  Eelix 
  

   subcarittatus, 
  Montagu. 
  I 
  have 
  been 
  unable 
  to 
  verify 
  this 
  statement 
  

   and 
  have 
  not 
  seen 
  any 
  refutation. 
  If 
  it 
  be 
  correct, 
  then 
  2'ornus 
  must 
  

   replace 
  Adeorhis 
  (as 
  Sacco 
  proposed), 
  which 
  was 
  not 
  introduced 
  b}' 
  

   Searles 
  Wood 
  until 
  1842 
  (Ann. 
  Mag. 
  Nat. 
  Hist., 
  ser. 
  i, 
  vol. 
  ix, 
  p. 
  530). 
  

   Four 
  species 
  Avere 
  included 
  in 
  Adeorhis 
  ; 
  the 
  first 
  was 
  described 
  as 
  

   striatus, 
  and 
  figured 
  on 
  pi. 
  v, 
  figs. 
  4-6 
  ; 
  the 
  next 
  two 
  are 
  nude 
  names 
  ; 
  

   the 
  last 
  was 
  subcarinatus, 
  Montagu. 
  By 
  all 
  the 
  laws 
  the 
  first 
  should 
  

   have 
  been 
  accepted 
  as 
  type, 
  but 
  Gray 
  in 
  the 
  Proc. 
  Zool. 
  Soc. 
  Lond., 
  

   1847, 
  designated 
  subcarinatus 
  as 
  type, 
  and 
  this 
  designation 
  has 
  been 
  

   followed. 
  Consequently 
  Adeorbis 
  would 
  become 
  a 
  pure 
  synonym 
  

   of 
  Tornus. 
  Sacco 
  incorrectly 
  has 
  used 
  Adeorbis 
  for 
  the 
  shells 
  typified 
  

   by 
  striatus, 
  which 
  Searles 
  Wood 
  himself 
  identified 
  with 
  Valvata 
  

   xtriata, 
  Philippi 
  (Enum. 
  Moll. 
  Sicil., 
  vol. 
  i, 
  p. 
  147, 
  pi. 
  ix, 
  figs. 
  Za-c, 
  

   1836). 
  This 
  species 
  was 
  later 
  made 
  the 
  type 
  of 
  a 
  new 
  genus, 
  

   Circulus, 
  by 
  Jeffreys 
  (Brit. 
  Conch., 
  vol. 
  iii, 
  p. 
  315, 
  1865).
