  When 
  Pilsbry 
  took 
  up 
  Carpenter's 
  description 
  of 
  Guildingia 
  ohtecta 
  

   he 
  did 
  not 
  fully 
  grasp 
  the 
  idea 
  of 
  the 
  shell, 
  otherwise 
  he 
  would 
  

   not 
  have 
  written

  This 
  

   section,

  Fannettia

  the

   Fremllya

  Adams, 
  described

  figured 
  in 
  1866 
  from 
  

   *' 
  unknown 
  habitat", 
  appears 
  to 
  have 
  received 
  very 
  little 
  attention 
  

   since. 
  In 
  1872 
  Hutton 
  described 
  a 
  New 
  Zealand 
  shell 
  as 
  Aeantho- 
  

   chcetes 
  ovatus. 
  

  

  In 
  1893 
  Pilsbry 
  included 
  both 
  under 
  Plaxiphora, 
  reducing 
  Fremllya 
  

   to 
  sectional 
  rank. 
  To 
  egregia 
  he 
  allotted 
  an 
  Australian 
  habitat 
  on 
  

   Carpenter's 
  MSS. 
  "collected 
  by 
  Dieflenbach, 
  N'ewcastle, 
  Australia", 
  

   and 
  as 
  a 
  synonym 
  gave 
  Streptochiton 
  tortuosus, 
  Cpr. 
  MSS. 
  olim. 
  

   He 
  also 
  gave 
  Carpenter's 
  manuscript 
  detailed 
  description 
  of 
  the 
  type. 
  

   In 
  the 
  British 
  Museum 
  are 
  the 
  type 
  tablet 
  and 
  three 
  other 
  tablets, 
  

   one 
  marked 
  " 
  Newcastle, 
  Australia, 
  Dieffenbach 
  ", 
  and 
  the 
  two 
  others 
  

   from 
  New 
  Zealand. 
  All 
  these 
  last 
  three 
  are 
  labelled 
  *S. 
  tortuosus, 
  

   Cpr 
  , 
  in 
  Carpenter's 
  handwriting. 
  

  

  As 
  Dieffenbach 
  collected 
  largely 
  in 
  New 
  Zealand, 
  I 
  consider 
  it 
  

   feasible 
  to 
  suppose 
  that 
  an 
  erroneous 
  label 
  has 
  been 
  attached 
  to 
  

   the 
  shells, 
  as 
  otherwise 
  it 
  is 
  unknown 
  from 
  Australia, 
  and 
  I 
  do 
  

   not 
  consider 
  it 
  should 
  be 
  included 
  in 
  Australian 
  lists. 
  

  

  There 
  can 
  be 
  no 
  doubt 
  that 
  all 
  the 
  specimens 
  are 
  conspecific, 
  and 
  

   as 
  egregia 
  has 
  priority 
  it 
  naust 
  replace 
  the 
  familiar 
  ovata. 
  

  

  Thiele 
  has 
  reinstated 
  Fremllya 
  as 
  a 
  full 
  genus, 
  but 
  I 
  cannot 
  yet 
  

   see 
  characters 
  sufficiently 
  strong 
  to 
  cause 
  me 
  to 
  follow 
  him.
