  examined 
  tlie 
  type, 
  and 
  repoTted 
  that 
  it 
  seemed 
  to 
  be 
  merely 
  

   A. 
  discrepans, 
  Brown, 
  a 
  common 
  European 
  species. 
  Pilsbry 
  deemed 
  

   this 
  identification 
  to 
  need 
  confirmation, 
  as 
  it 
  was 
  founded 
  on 
  an 
  

   examination 
  of 
  external 
  characters 
  only. 
  

  

  I 
  have 
  disarticulated 
  the 
  specimen, 
  and 
  find 
  there 
  is 
  no 
  doubt 
  

   whatever 
  tliat 
  the 
  shell 
  is 
  simply 
  A. 
  discrepans, 
  Brown. 
  As 
  all 
  

   other 
  European 
  shells 
  named 
  by 
  Adams 
  as 
  coming 
  from 
  Australia 
  

   have 
  been 
  disallowed, 
  I 
  conclude 
  carinatus, 
  Ad. 
  «&; 
  Ang., 
  must 
  be 
  

   omitted 
  from 
  the 
  Australian 
  lists, 
  and 
  must 
  be 
  added 
  to 
  the 
  synonymy 
  

   of 
  discrepajis, 
  Brown.

   I 
  cannot 
  separate

  the

   earlier

   Upon 
  Hutton's 
  suggestion 
  Pilsbry 
  included 
  this 
  species 
  as 
  a 
  

   synonym 
  of 
  C. 
  canalicidatus, 
  Q. 
  &

   In 
  1897 
  Suter, 
  revising 
  the 
  j^ew 
  Zealand 
  Polyplacophora 
  (Proc. 
  

   Malac. 
  Soc, 
  vol. 
  ii, 
  p. 
  196), 
  reintroduced 
  it 
  as 
  a 
  valid 
  species 
  for 
  

   a 
  specimen 
  he 
  had 
  found 
  at 
  Lyttelton. 
  He 
  drew 
  up 
  a 
  detailed 
  

   description, 
  pointing 
  out 
  how 
  diiferent 
  it 
  was 
  from 
  canaliculatus. 
  

   Later 
  I 
  found 
  also 
  in 
  Lyttelton 
  Harbour 
  two 
  specimens, 
  each 
  of 
  

   which 
  were 
  named 
  for 
  me 
  by 
  Mr. 
  Suter 
  from 
  his 
  specimen 
  as 
  

   Stangeri, 
  Beeve. 
  Examination 
  of 
  the 
  type 
  of 
  Stangeri, 
  Beeve, 
  

   shows 
  it 
  to 
  be 
  merely 
  canaliculatus, 
  Q. 
  & 
  G., 
  as 
  Pilsbry 
  placed 
  it, 
  

   and 
  moreover 
  very 
  typically 
  so, 
  not 
  even 
  a 
  variety.

  At 
  the 
  place 
  quoted 
  Suter 
  diagnoses 
  this 
  shell 
  as 
  follows 
  : 
  In 
  

   size, 
  shape, 
  and 
  coloration 
  very 
  much 
  like 
  Chiton 
  limans, 
  but 
  differing 
  

   on 
  the 
  following 
  points. 
  The 
  ribs 
  have 
  no 
  acute 
  elevated 
  grains, 
  

   but 
  are 
  flattened. 
  The 
  tail-valve 
  has 
  very 
  distinct, 
  flatly 
  nodulous 
  

   ribs. 
  The 
  jugum 
  is 
  less 
  acute, 
  divergence 
  120°. 
  The 
  imbricating 
  

   scales 
  of 
  the 
  girdle 
  are 
  very 
  small 
  on 
  both 
  margins, 
  larger 
  in 
  the 
  

   middle, 
  shining, 
  not 
  mucronated, 
  and 
  very 
  faintly 
  striated, 
  the 
  strise 
  

   being 
  only 
  visible 
  under 
  strong 
  magnifying 
  power. 
  Length

  Suter's

  This 
  very 
  distinct 
  species 
  is 
  at 
  present 
  known 
  by 
  three 
  specimens, 
  

   all 
  from 
  Lyttelton 
  Harbour. 
  The 
  shell 
  I 
  have 
  used 
  for 
  comparison
