  Under 
  the 
  name 
  Txdufa 
  {Crossata) 
  Californica, 
  Hinds, 
  Suter 
  has 
  

   recorded 
  this 
  shell 
  from 
  the 
  Kermadecs 
  (Trans.

  Zeal. 
  Inst., 
  1905 
  

   (1906), 
  vol. 
  xxxviii,

  I 
  have 
  compared 
  the 
  shells 
  I 
  collected 
  

   with 
  the 
  shell 
  in 
  the 
  Auckland 
  Museum 
  upon 
  which 
  Suter 
  based 
  his 
  

   record, 
  and 
  they 
  are 
  undoubtedly 
  the 
  same, 
  and 
  are 
  as 
  certainly 
  

   Reeve's 
  siphonatum.

  A 
  unique 
  shell 
  of 
  unknown 
  habitat 
  in 
  the 
  British 
  Museum 
  was 
  

   figured 
  by 
  Wood. 
  Eight 
  years 
  later 
  this 
  same 
  specimen 
  was 
  given 
  

   a 
  new 
  name 
  and 
  refigured 
  by 
  Sowerby. 
  Kiener, 
  Reeve, 
  and 
  Tryon 
  

   have 
  reproduced 
  Sowerby's 
  figures 
  and 
  name, 
  and 
  ignored 
  Wood's 
  

   figure. 
  Tryon 
  reduced 
  it 
  to 
  a 
  synonym 
  of 
  cruentata, 
  Sowb., 
  but 
  it 
  is 
  

   a 
  very 
  distinct 
  and 
  easily 
  recognizable 
  form. 
  It 
  was 
  constantly 
  

   occurring 
  in 
  a 
  very 
  much 
  damaged 
  state 
  on 
  the 
  beach 
  of 
  Sunday 
  

   Island, 
  but 
  no 
  live 
  specimens 
  were 
  obtained.

  The 
  latter 
  name 
  was 
  reduced 
  to 
  a 
  synonym 
  by 
  Tryon 
  (Man. 
  Conch., 
  

   ser. 
  I, 
  vol. 
  iii, 
  p. 
  17), 
  and 
  in 
  this 
  case 
  this 
  course 
  is 
  justified. 
  Specimens 
  

   collected 
  at 
  Sunday 
  Island 
  were 
  identified 
  by 
  Mr. 
  Hedley 
  as 
  the 
  shell 
  

   known 
  to 
  him 
  as 
  Strangei, 
  Ad. 
  & 
  Aug., 
  and 
  they 
  are 
  undoubtedly 
  the 
  

   same 
  as

  On 
  the 
  beach 
  occurred 
  rarely 
  specimens 
  of 
  a 
  small 
  Cassidea, 
  usually 
  

   very 
  imperfect. 
  One 
  was 
  washed 
  up 
  alive, 
  but 
  in 
  that 
  case 
  the 
  shell 
  

   was 
  badly 
  smashed. 
  Examination 
  of 
  the 
  literature 
  showed 
  nothing 
  

   exactly 
  like 
  it, 
  but 
  in 
  the 
  British 
  Museum 
  specimens 
  of 
  the 
  above 
  

   species 
  agreed 
  perfectly, 
  though 
  the 
  figure 
  did 
  not. 
  It 
  was 
  described 
  

   from 
  Mauritius, 
  which 
  is 
  an 
  immense 
  distance 
  from 
  Sunday 
  Island. 
  

   The 
  species 
  of 
  the 
  genus 
  Cassidea 
  seem 
  very 
  imperfectly 
  known, 
  as 
  

   Melvill 
  (Journ. 
  Conch., 
  1905, 
  vol. 
  ii, 
  pp. 
  176 
  seq.), 
  writing 
  of 
  them 
  

   as 
  Casmaria, 
  H. 
  & 
  A. 
  Ad., 
  only 
  included 
  two 
  species 
  with 
  perhaps 
  

   four 
  sub-species. 
  In 
  that 
  paper 
  he 
  overlooked 
  this 
  species, 
  making 
  no 
  

   reference 
  whatever 
  to 
  it.
