  PROCEKDINGS

  SOCIETY. 
  

  

  DoTOXA, 
  gen. 
  nov. 
  for 
  Melihcea 
  frag 
  His, 
  Forbes. 
  

  

  In 
  other 
  ways 
  than 
  tlie 
  preceding, 
  Nudibraiich 
  names 
  show 
  

   confusion, 
  and 
  I 
  propose 
  Dotona 
  for 
  the 
  species 
  Melihcea 
  fragilis, 
  

   Forbes 
  (Malac. 
  Monensis, 
  1838, 
  p. 
  4), 
  the 
  genus 
  name 
  i)o^o 
  quoted 
  as 
  

   of 
  Oken, 
  1815, 
  having 
  been 
  used 
  in 
  1807 
  by 
  the 
  same 
  author 
  in 
  

   a 
  different 
  sense. 
  

  

  Galvina, 
  Alder 
  & 
  Hancock, 
  is 
  in 
  use 
  for 
  a 
  group 
  of 
  which 
  one 
  

   species 
  is 
  the 
  monotype 
  of 
  Euhranchus, 
  Forbes, 
  1838 
  (loc. 
  cit.), 
  

   which 
  has 
  priority. 
  Many 
  more 
  instances 
  of 
  tliis 
  character 
  occur, 
  

   the 
  case 
  of 
  Lomanotus, 
  Verany, 
  being 
  on 
  a 
  parallel 
  with 
  Tritunia, 
  

   Verany's 
  name, 
  1844-6, 
  being 
  intercepted 
  by 
  Eumenis, 
  Alder 
  & 
  

   Hancock, 
  1845, 
  which 
  has 
  been 
  rejected. 
  

  

  Laskeya, 
  nom. 
  nov. 
  for 
  Eumeta, 
  Morch, 
  1868. 
  

   Kecently 
  I 
  concluded 
  that 
  Eameta 
  was 
  the 
  valid 
  generic 
  name 
  for 
  

   a 
  British 
  shell, 
  because 
  the 
  name 
  had 
  been 
  accepted 
  by 
  Tliiele, 
  Hedley, 
  

   etc. 
  I 
  overlooked 
  the 
  fact, 
  as 
  my 
  co-workers 
  had 
  done, 
  that 
  it 
  was 
  

   preoccupied 
  by 
  Walker. 
  I 
  therefore 
  propose 
  Lasheya, 
  noni. 
  nov. 
  for 
  

   Eumeta, 
  Miirch, 
  1868. 
  I 
  would 
  note 
  that 
  Locard 
  introduced 
  Cerithio- 
  

   limim 
  (Ann. 
  Soc. 
  Agric. 
  Lyon, 
  ser. 
  ii, 
  vol. 
  x, 
  1903, 
  p. 
  110) 
  as 
  a 
  new 
  

   name 
  for 
  Loveyiella, 
  Sars, 
  1878, 
  about 
  twenty 
  years 
  too 
  late. 
  

  

  CoLXONisTA, 
  gen. 
  nov. 
  for 
  Collonia 
  picta, 
  Pease. 
  

   The 
  genus 
  name 
  Collonia 
  has 
  been 
  discussed 
  and 
  is 
  now 
  relegated 
  

   to 
  fossils 
  agreeing 
  with 
  the 
  type. 
  Tliere 
  seems 
  to 
  be 
  a 
  recent 
  group 
  

   having 
  much 
  the 
  same 
  features. 
  Leptotliyra 
  proves 
  to 
  have 
  been 
  first 
  

   published 
  by 
  Pease 
  in 
  connexion 
  with 
  a 
  juvenile 
  shell 
  of 
  a 
  different 
  

   genus. 
  The 
  matter 
  is 
  complex 
  and 
  needs 
  careful 
  handling, 
  but 
  

   I 
  here 
  remedy 
  one 
  item 
  by 
  the 
  above 
  proposition. 
  

  

  Talopena, 
  gen. 
  nov. 
  for 
  Monilea 
  incerta, 
  Iredale. 
  

  

  Under 
  the 
  name 
  Monilea 
  many 
  different 
  shell 
  groups 
  have 
  been 
  

   confused, 
  and 
  when 
  E. 
  A. 
  Smith 
  pointed 
  out 
  that 
  Swainson's 
  

   description 
  negatived 
  liis 
  tentative 
  reference 
  of 
  his 
  type 
  to 
  " 
  callifera, 
  

   Lam.", 
  he 
  used 
  Solariella, 
  S. 
  V. 
  Wood. 
  That 
  name 
  given 
  to 
  a 
  Crag 
  

   fossil 
  should 
  not 
  be 
  used 
  in 
  connexion 
  with 
  recent 
  shells 
  showing 
  

   unlike 
  shell 
  characters. 
  Gray 
  proposed 
  Talojjia, 
  apparently 
  for 
  the 
  

   callifera 
  group, 
  but 
  without 
  diagnosing 
  it, 
  and 
  later 
  cited 
  it 
  as 
  

   a 
  synonym 
  of 
  Monilea, 
  Swaiuson, 
  giving 
  callifera, 
  Lam., 
  as 
  type 
  of 
  

   the 
  genus. 
  Consequently, 
  I 
  conclude 
  'Talopia 
  would 
  become 
  valid 
  

   for 
  the 
  callifera 
  group. 
  This, 
  however, 
  is 
  not 
  congeneric 
  with 
  the 
  

   austral 
  species 
  commonly 
  referred 
  to 
  Monilea, 
  and 
  two 
  other 
  names 
  

   have 
  been 
  cited 
  in 
  conjunction 
  with 
  them. 
  

  

  Mitiolia, 
  A. 
  Adams, 
  and 
  Conotrochus, 
  Pilsbry, 
  the 
  latter 
  afterwards 
  

   being 
  considered 
  by 
  its 
  author 
  as 
  synonymous 
  with 
  the 
  former. 
  

   Since 
  the 
  last-named 
  is 
  an 
  invalid 
  name, 
  certain 
  corrections 
  seem 
  

   necessary. 
  

  

  I 
  herewith 
  propose 
  Talopena 
  for 
  Monilea 
  incerta, 
  which 
  I 
  described 
  

   from 
  the 
  Kermadecs, 
  and 
  which 
  is 
  typical 
  of 
  a 
  well-marked 
  austral 
  

   series.
