  with 
  Stangeri, 
  Reeve, 
  is 
  one 
  named 
  by 
  jMr. 
  Suter 
  from 
  his 
  specimen 
  

   described 
  above. 
  It 
  is 
  very 
  slightly 
  smashed 
  and 
  curled, 
  and 
  

   measures 
  11 
  J 
  mm. 
  X 
  7^ 
  mm. 
  The 
  pleural 
  areas 
  are 
  sculptured 
  

   with 
  six 
  sulci, 
  widely 
  spaced 
  and 
  extending 
  right 
  across 
  ; 
  the 
  dorsal 
  

   ridge 
  quite 
  smooth. 
  The 
  valves 
  are 
  beaked. 
  The 
  feature 
  which 
  

   separates 
  it 
  immediately 
  from 
  canaJiculatus, 
  Q,. 
  & 
  G., 
  is 
  the 
  sculpture 
  

   of 
  the 
  pleural 
  areas. 
  In 
  Pilsbry's 
  monograph 
  the 
  peculiar 
  wavy 
  

   sulci 
  of 
  that 
  species 
  is 
  well 
  shown 
  in 
  fig. 
  4 
  of 
  pi. 
  xxxvi. 
  The 
  

   sulci 
  of 
  Suteri 
  are 
  perfectly 
  straight, 
  and 
  much 
  fewer 
  than 
  in 
  

   a 
  canalicidatus 
  of 
  the 
  same 
  size. 
  I 
  should 
  even 
  consider 
  it 
  nearer 
  

   cereus, 
  Reeve, 
  than 
  either 
  limans, 
  Sykes, 
  or 
  canaliculatus, 
  Q,. 
  & 
  G., 
  but 
  

   whatever 
  it 
  is 
  compared 
  with 
  it 
  is 
  an 
  easily 
  separable 
  shell.

   . 
  In 
  honouring 
  Dr. 
  Torr, 
  Messrs. 
  Hedley 
  & 
  Hull 
  overlooked 
  the 
  

   fact 
  that 
  Mr. 
  Suter 
  (Proc. 
  Malac. 
  Soc, 
  1907, 
  vol. 
  vii, 
  p. 
  295, 
  

   fig. 
  2 
  in 
  text) 
  had 
  anticipated 
  them 
  in 
  attaching 
  Torr's 
  name 
  to 
  

   a 
  Chiton. 
  In 
  the 
  hope 
  that 
  they 
  have 
  not 
  corrected 
  this 
  error 
  I 
  am 
  

   venturing 
  to 
  suggest 
  the 
  above 
  to 
  designate 
  this 
  South 
  Australian 
  

   species. 
  In 
  connexion 
  with 
  it 
  and 
  Coxi, 
  Pils., 
  I 
  wish 
  to 
  point 
  out 
  

   that 
  Thiele 
  has 
  published 
  a 
  new 
  species, 
  lellidus, 
  from 
  JSTew 
  South 
  

   Wales 
  (Zool. 
  Chun, 
  Heft 
  Ivi, 
  p. 
  93, 
  pi. 
  x, 
  figs. 
  5-8). 
  This 
  species 
  

   was 
  compared 
  by 
  Thiele 
  with 
  jugosus, 
  Gld., 
  but 
  not 
  with 
  Coxi, 
  Pils. 
  

   Upon 
  looking 
  in 
  the 
  British 
  Museum 
  for 
  specimens 
  of 
  the 
  latter 
  

   species, 
  I 
  could 
  only 
  find 
  one 
  from 
  South 
  Australia. 
  I 
  noted 
  that 
  

   this 
  specimen 
  differed 
  from 
  my 
  recollections 
  of 
  shells 
  of 
  Coxi 
  

   collected 
  in 
  Port 
  Jackson 
  when 
  in 
  company 
  with 
  Mr. 
  Basset 
  Hull, 
  

   so 
  I 
  did 
  not 
  use 
  it 
  for 
  comparison. 
  I 
  therefore 
  certainly 
  agree 
  

   with 
  Messrs. 
  Hedley 
  & 
  Hull's 
  remarks 
  concerning 
  the 
  relationships 
  

   of 
  Hullianus 
  and 
  Coxi. 
  I 
  would 
  like 
  to 
  note 
  that 
  when 
  at 
  Caloundra, 
  

   Queensland, 
  I 
  collected 
  one 
  specimen 
  of 
  a 
  new 
  species, 
  which, 
  

   being 
  very 
  closely 
  related 
  to 
  Coxi, 
  Pils., 
  may 
  be 
  its 
  northern 
  repre- 
  

   sentative. 
  There 
  can 
  be 
  no 
  doubt 
  that 
  hellulus, 
  Thiele, 
  is 
  the 
  same 
  

   as 
  Coxi, 
  Pils., 
  from 
  a 
  study 
  of 
  Hedley 
  & 
  Hull's 
  beautiful 
  figures.
