   As 
  I 
  had 
  concerned 
  myself 
  principally 
  with 
  specific 
  determinations, 
  

   I 
  am 
  enabled 
  to 
  add 
  to 
  some 
  of 
  his 
  notes 
  and 
  confirm 
  others, 
  whilst 
  

   with 
  very 
  few 
  I 
  disagree. 
  This 
  paper 
  is 
  a 
  medley 
  of 
  notes 
  covering 
  

   all 
  the 
  genera 
  of 
  the 
  Polyplacophora, 
  and 
  will 
  be 
  succeeded 
  by 
  further 
  

   contributions 
  on 
  the 
  same 
  lines. 
  I 
  have 
  just 
  received 
  a 
  paper 
  on 
  

   Port 
  Jackson 
  Chitons 
  by 
  my 
  good 
  friends 
  Messrs. 
  Hedley 
  and 
  Hull, 
  

   and 
  find 
  they 
  have 
  notes 
  on 
  two 
  of 
  the 
  species 
  here 
  treated. 
  

  

  I 
  wish 
  to 
  thank 
  Mr. 
  E. 
  R. 
  Sykes 
  for 
  the 
  pleasure 
  of 
  examining 
  

   well-authenticated 
  Australian 
  Plaxiphora.

   In 
  1880 
  Filhol 
  described 
  (?) 
  a 
  shell 
  which 
  he 
  had 
  collected 
  at 
  

   Campbell 
  Island 
  under 
  the 
  name 
  Tonicia 
  Gryei. 
  Later 
  Kochebrune 
  

   described 
  (?) 
  a 
  shell 
  which 
  Filhol 
  had 
  collected 
  at 
  Campbell 
  Island 
  

   under 
  the 
  name 
  Lepidopleurus 
  melanterus. 
  Both 
  descriptions 
  were 
  

   inadequate, 
  and 
  in 
  each 
  case 
  the 
  generic 
  disposition 
  inaccurate. 
  

  

  I 
  received 
  from 
  the 
  Paris 
  Museum 
  a 
  bottle 
  containing 
  a 
  large 
  

   number 
  of 
  shells 
  with 
  Rochebrune's 
  label 
  attached 
  to 
  them. 
  The 
  

   whereabouts 
  of 
  Filhol' 
  s 
  shells 
  was 
  unknown. 
  As 
  these 
  shells 
  answer 
  

   Filhol's 
  description, 
  such 
  as 
  it 
  is, 
  I 
  consider 
  they 
  are 
  the 
  original 
  lot, 
  

   and 
  in 
  justice 
  to 
  Filhol 
  as 
  the 
  collector 
  as 
  well 
  as 
  describer, 
  they 
  

   should 
  bear 
  his 
  prior 
  name. 
  

  

  Thiele, 
  having 
  examined 
  these 
  same 
  shells, 
  has 
  declared 
  the 
  

   identity 
  of 
  Parlceri, 
  Suter, 
  and 
  fulvus, 
  Suter, 
  with 
  them 
  (Zool. 
  

   Chun,

  Ivi, 
  p.

  Previous 
  to 
  the 
  receipt 
  of 
  Thiele's 
  work 
  

   and 
  the 
  Pai'is 
  shells 
  I 
  had 
  found 
  myself 
  unable 
  to 
  separate 
  Parkeri,
