  Pilsbry 
  believed 
  C. 
  Halini, 
  Roche., 
  to 
  be 
  identical, 
  and 
  gives 
  rei^ro- 
  

   ductions 
  of 
  Eochebrune's 
  figures 
  under 
  this 
  species. 
  I 
  have 
  seen 
  the 
  

   type 
  of 
  Kochebrune's 
  species, 
  and 
  find 
  that 
  it 
  is 
  simply 
  a 
  ' 
  setiger

  The 
  type 
  tablet 
  of 
  Carmichcelis, 
  Gray, 
  bore 
  two 
  specimens, 
  both 
  

   about 
  the 
  same 
  size, 
  one 
  straight 
  and 
  one 
  curled. 
  The 
  latter 
  was 
  the 
  

   one 
  figured 
  by 
  Wood, 
  whose 
  name 
  has 
  priority. 
  Sykes 
  in 
  his 
  account 
  

   of 
  the 
  Polyplacophora 
  of 
  South 
  Africa 
  pointed 
  out 
  that 
  though 
  Pilsbry 
  

   doubted 
  the 
  accuracy 
  of 
  Gray's 
  attachment 
  of 
  setiger, 
  King, 
  to 
  

   CarmichcBlis 
  he 
  had 
  examined 
  the 
  specimens, 
  and 
  concluded 
  that 
  setiger 
  

   must 
  give 
  way 
  to 
  Carmichmlis, 
  which 
  must 
  be 
  crossed 
  off 
  the 
  South 
  

   African 
  list. 
  There 
  are 
  many 
  specimens 
  of 
  setiger, 
  King, 
  from 
  King's 
  

   collection 
  in 
  the 
  British 
  Museum, 
  varying 
  in 
  size 
  from 
  that 
  of 
  

   Carmiclmlis 
  to 
  specimens 
  40 
  mm. 
  in 
  length, 
  and 
  upon 
  dissecting 
  one 
  

   of 
  the 
  small 
  specimens 
  for 
  comparison 
  with 
  one 
  of 
  the 
  types 
  of 
  

   CarmichcBlis 
  no 
  points 
  of 
  difference 
  could 
  be 
  detected. 
  The 
  external 
  

   characters 
  were 
  absolutely 
  identical. 
  Hence 
  the 
  name 
  setiger, 
  King, 
  

   must 
  give 
  waj' 
  to 
  Carmichcelis, 
  Wood. 
  

  

  From 
  South 
  America 
  and 
  the 
  Falkland 
  Islands 
  two 
  verj' 
  distinctly 
  

   coloured 
  shells 
  are 
  received, 
  and 
  I 
  believe 
  they 
  must 
  be 
  separate 
  

   species. 
  I 
  hope 
  to 
  refer 
  to 
  this 
  later, 
  but 
  in 
  the 
  meantime 
  the 
  above 
  

   names 
  are 
  absolutely 
  synonymous 
  through 
  examination 
  of 
  the 
  types.

  In 
  the 
  Manual 
  of 
  Conchology 
  Pilsbry 
  included 
  pethoJata, 
  Sowerby, 
  

   to 
  which 
  he 
  attached 
  Adams 
  & 
  Angas's 
  conspersa, 
  as 
  a 
  variety 
  upon 
  

   Carpenter's 
  MS., 
  and 
  glauca, 
  Quoy 
  & 
  Gaiuiard, 
  as 
  Australian, 
  with 
  

   a 
  new 
  species 
  of 
  Carpenter, 
  excurvata, 
  as 
  perhaps 
  Australian 
  members 
  

   of 
  the 
  genus 
  PlaxipJiora. 
  J^either 
  conspersa, 
  Ad. 
  & 
  Aug., 
  nor 
  glauca, 
  

   Q. 
  «& 
  G., 
  had 
  he 
  seen. 
  Later, 
  dealing 
  with 
  Port 
  Jackson 
  Chitons, 
  

   he 
  only 
  recorded 
  petholata. 
  Sow., 
  from 
  that 
  locality. 
  Sykes 
  only 
  

   allowed 
  petholata, 
  Sow., 
  when 
  he 
  catalogued 
  the 
  Victorian 
  Chitons. 
  

   Bednall 
  from 
  South 
  Australia 
  recorded 
  three 
  species 
  — 
  petholata. 
  Sow., 
  

   conspersa. 
  Ad. 
  & 
  Aug., 
  and 
  glauca, 
  Q. 
  & 
  G. 
  

  

  Bj' 
  Australian 
  students 
  these 
  were 
  easily 
  separated 
  by 
  superficial 
  

   characters, 
  petholata, 
  Sow., 
  being 
  the 
  common 
  variable 
  corrugated 
  

   species, 
  conspersa. 
  Ad. 
  & 
  Ang., 
  being 
  a 
  very 
  distinctive 
  small 
  shell, 
  

   and 
  glauca, 
  Q,. 
  & 
  G., 
  being 
  a 
  big 
  smoothish 
  shell. 
  Only 
  so-called 
  

   petholata. 
  Sow., 
  was 
  collected 
  at 
  Port 
  Jackson 
  by 
  Mr. 
  A. 
  F. 
  Basset 
  

   Hull, 
  and 
  to 
  him 
  there 
  appeared 
  to 
  be 
  two 
  species 
  confused 
  under 
  

   that 
  name. 
  He 
  asked 
  me 
  to 
  look 
  into 
  the 
  matter 
  and 
  find 
  out 
  which 
  

   was 
  Sowerby's 
  species. 
  

  

  The 
  types 
  of 
  Sowerby's 
  petholata, 
  as 
  also 
  the 
  variety 
  porphyrins, 
  

   which 
  has 
  never 
  been 
  recognized, 
  are, 
  however, 
  non-existent.
