  will

  Matena, 
  gen. 
  nov. 
  

   I 
  propose 
  this 
  name 
  for 
  Biplex 
  australasia. 
  Perry. 
  In 
  these 
  

   Proceedings 
  (vol. 
  xi, 
  1915, 
  p. 
  284) 
  the 
  late 
  Mr. 
  E. 
  A. 
  Smith, 
  after 
  

   relating 
  the 
  peregrinations 
  of 
  this 
  species 
  from 
  one 
  genus 
  to 
  another, 
  

   citing 
  Biplex, 
  Ranella, 
  Triton, 
  Bursa, 
  Gyrineum, 
  Apollon, 
  Lotorium, 
  

   Argobuccinum, 
  and 
  <S^/?^«, 
  and 
  rejecting 
  all 
  these, 
  placed 
  it 
  in 
  Charonia. 
  

   Privately 
  he 
  admitted 
  this 
  was 
  only 
  a 
  tentative 
  location, 
  but 
  

   conservatively 
  declined 
  to 
  propose 
  for 
  it 
  a 
  new 
  generic 
  name, 
  though 
  

   not 
  adverse 
  to 
  such 
  a 
  suggestion. 
  Simultaneously 
  Bartsch, 
  dealing 
  

   with 
  South 
  African 
  shells, 
  classed 
  the 
  South 
  African 
  representative 
  

   in 
  still 
  another 
  genus, 
  viz. 
  Eugyrina. 
  Tlie 
  species 
  have 
  a 
  peculiar 
  

   facies, 
  and, 
  as 
  can 
  be 
  guessed 
  from 
  the 
  above 
  resume, 
  do 
  not 
  correlate 
  

   well 
  with 
  any 
  named 
  group. 
  Since 
  Smith's 
  account 
  we 
  have 
  benefited 
  

   by 
  the 
  publication 
  in 
  these 
  Proceedings 
  (vol. 
  xii, 
  1916, 
  pp. 
  5 
  etseqq.) 
  

   of 
  a 
  valuable 
  paper 
  entitled 
  "On 
  the 
  Operculum 
  of 
  Bursa", 
  by 
  the 
  

   llev. 
  Dr. 
  Cooke. 
  After 
  discussing 
  this 
  point. 
  Dr. 
  Cooke 
  added, 
  

   " 
  The 
  evidence 
  of 
  the 
  radula 
  . 
  . 
  ." 
  and 
  from 
  this 
  it 
  is 
  easily 
  seen 
  

   that 
  the 
  radula 
  of 
  the 
  present 
  group 
  is 
  as 
  discordant 
  as 
  the 
  shell 
  

   characters. 
  " 
  Unlike 
  both 
  Bursa 
  and 
  ' 
  Triton' 
  proper" 
  are 
  Cooke's 
  

   words, 
  and 
  figures 
  are 
  given 
  to 
  prove 
  this 
  statement. 
  Had 
  this 
  

   evidence 
  been 
  available 
  to 
  Smitli 
  his 
  doubt 
  would 
  have 
  been 
  

   dissipated 
  and 
  he 
  would 
  have 
  certainly 
  proposed 
  a 
  generic 
  term 
  for 
  

   the 
  species. 
  I 
  state 
  this 
  because 
  I 
  often 
  discussed 
  the 
  matter 
  with 
  

   liim, 
  and 
  now 
  remedy 
  the 
  matter 
  by 
  introducing 
  the 
  above 
  name, 
  in 
  

   honour 
  of 
  Mr. 
  W. 
  L. 
  May, 
  the 
  Tasmanian 
  conchologist, 
  to 
  whom 
  all 
  

   students 
  are 
  indebted 
  for 
  many 
  valuable 
  items. 
  Only 
  two 
  species 
  

   are 
  known, 
  australasia, 
  Perry, 
  and 
  gemmifera, 
  Euthyme.

  &

  Adams. 
  

   In 
  the 
  consideration 
  of 
  molluscan 
  generic 
  names 
  some 
  extraordinary 
  

   cases 
  bewilder 
  the 
  student. 
  The 
  present 
  is 
  one 
  of 
  these. 
  Turricula 
  

   Avas 
  proposed 
  by 
  Schumacher 
  in 
  the 
  Essai 
  Nouv. 
  Syst. 
  Test., 
  

   1817, 
  pp. 
  66, 
  217, 
  for 
  the 
  species 
  Turricula 
  flammea 
  alone, 
  based 
  on 
  

   Chemn., 
  iv, 
  p. 
  172, 
  tab. 
  143, 
  figs. 
  1336-8. 
  In 
  the 
  Gen. 
  Rec. 
  Moll., 
  

   vol. 
  i, 
  1853, 
  p. 
  88, 
  H. 
  & 
  A. 
  Adams 
  introduced 
  Surcula 
  for 
  " 
  Turri- 
  

   cula, 
  Sebum, 
  non 
  Klein". 
  Adams' 
  name 
  has 
  continued 
  in 
  usage 
  

   ever 
  since, 
  though 
  it 
  was 
  early 
  recognized 
  that 
  Klein's 
  names 
  had 
  

   no 
  effect 
  upon 
  present-day 
  nomenclatorial 
  use. 
  I 
  noted 
  that 
  there 
  

   was 
  a 
  Turricula, 
  Hermann, 
  which 
  was 
  not 
  nomenclatorially 
  valid, 
  

   and 
  therefore 
  the 
  first 
  user 
  after 
  Hermann's 
  time 
  had 
  a 
  perfect 
  claim. 
  

   This 
  proves 
  to 
  be 
  Schumacher, 
  and 
  at 
  the 
  present 
  time 
  I 
  know 
  of 
  no 
  

   reason 
  why 
  his 
  name 
  should 
  not 
  be 
  resumed 
  vice 
  Surcula.

  In 
  1869 
  a 
  Catalogue 
  of 
  the 
  Paetel 
  Collection 
  was 
  published, 
  and 
  

   a 
  systematic 
  synopsis 
  given, 
  the 
  whole 
  prepared 
  by 
  Scliaufuss. 
  

   A 
  few 
  of 
  the 
  names 
  were 
  altered 
  by 
  Schaufuss, 
  and 
  most 
  have 
  been
