  Dr. 
  Coppinger 
  dredged 
  this 
  species 
  at 
  the 
  first 
  locality 
  in 
  7 
  

   fathoms. 
  It 
  must 
  not 
  be 
  confused 
  with 
  //. 
  hrevis, 
  Quoy, 
  which 
  is 
  a 
  

   shorter 
  shell 
  with 
  more 
  convex 
  outlines. 
  I 
  would 
  here 
  call 
  atten- 
  

   tion 
  to 
  a 
  few 
  inaccuracies 
  in 
  Professor 
  Hutton's 
  English 
  translation 
  

   of 
  the 
  original 
  Latin 
  diagnosis 
  (' 
  Manual 
  of 
  New-Zealand 
  MoUusca,' 
  

   p. 
  122). 
  The 
  epidermis 
  was 
  described 
  by 
  me 
  as 
  whitish, 
  not 
  

   " 
  white," 
  and 
  I 
  did 
  not 
  say 
  it 
  was 
  " 
  shining 
  near 
  the 
  vertex." 
  

   The 
  word 
  shining 
  applied 
  to 
  the 
  whole 
  of 
  the 
  surface, 
  and 
  is 
  

   followed 
  by 
  a 
  comma 
  which 
  disconnects 
  it 
  from 
  the 
  words 
  " 
  verticem 
  

   basimque 
  versus 
  luteo 
  tincto 
  " 
  which 
  succeed. 
  " 
  Incrementi 
  lineis 
  

   et 
  superius 
  basique 
  transversim 
  subdistanter 
  striata 
  " 
  is 
  thus 
  ren- 
  

   dered 
  — 
  " 
  transversely 
  subdistantly 
  striated 
  with 
  lines 
  of 
  growth, 
  both 
  

   above 
  and 
  below." 
  Capt. 
  Hutton 
  makes 
  the 
  labrum 
  " 
  thin, 
  thickened 
  

   in 
  the 
  middle," 
  whilst 
  no 
  such 
  thing 
  is 
  said 
  in 
  the 
  diagnosis. 
  

   The 
  words 
  are 
  " 
  labrum 
  tenue, 
  verticis 
  medio 
  junctum 
  et 
  ibi 
  in- 
  

   crassatum."

  In

  the

  I

  can 
  see 
  no 
  distinction. 
  Angas 
  (P. 
  Z. 
  8. 
  1867, 
  p. 
  227) 
  comes 
  to 
  

   a 
  similar 
  conclusion. 
  The 
  more 
  slender 
  form 
  referred 
  to 
  by 
  Sowerby 
  

   in 
  the 
  ' 
  Conch. 
  Icon.' 
  is 
  altogether 
  a 
  variable 
  character 
  in 
  this 
  shell; 
  

   the 
  elevation 
  of 
  the 
  spire 
  above 
  or 
  its 
  depression 
  beneath 
  the 
  body- 
  

   whorl 
  is 
  likewise 
  an 
  unreliable 
  characteristic.
