  the 
  figures 
  

   given 
  by 
  Weinkauff 
  (pi.

  figs. 
  9-10) 
  are 
  very 
  unsatisfactory, 
  

   both 
  as 
  regards 
  colour

  the 
  denticulation

  The 
  description 
  given 
  by 
  Gray 
  of 
  the 
  colour, 
  "white, 
  with 
  three 
  

   bright 
  crimson 
  cross 
  bands," 
  or 
  that 
  of 
  Sowerby, 
  "whitish, 
  with 
  

   three 
  red 
  transverse 
  bands," 
  correctly 
  indicates 
  the 
  coloration 
  of 
  the 
  

   typical 
  form 
  of 
  this 
  species, 
  Avhich 
  apparently 
  is 
  restricted 
  to 
  East 
  

   Australia. 
  The 
  apical 
  whorls 
  are 
  generally 
  yellowish 
  olive 
  or 
  amber, 
  

   and 
  the 
  anterior 
  tip 
  of 
  the 
  body-whorl 
  is 
  also 
  stained 
  with 
  pale 
  

   olivaceous 
  brown. 
  The 
  three 
  red 
  bands 
  are 
  most 
  distinct 
  dorsally, 
  

   the 
  uppermost 
  at 
  the 
  upper 
  part 
  of 
  the 
  body-whorl 
  being 
  the 
  broadest, 
  

   and 
  the 
  intermediate 
  one 
  is 
  just 
  below 
  the 
  middle. 
  They 
  do 
  not 
  

   extend 
  on 
  to 
  the 
  labrum. 
  On 
  the 
  ventral 
  side 
  the 
  uppermost 
  one 
  is 
  

   the 
  most 
  apparent, 
  the 
  lowermost 
  is 
  less 
  pronounced, 
  and 
  the 
  central 
  

   one 
  is 
  almost 
  obsolete. 
  The 
  labrum 
  has 
  from 
  twenty 
  to 
  twenty-two 
  

   denticles 
  in 
  the 
  largest 
  specimens, 
  and 
  rather 
  fewer 
  in 
  smaller 
  ones. 
  

   At 
  the 
  anterior 
  end 
  of 
  the 
  columella 
  there 
  are 
  four 
  or 
  five 
  transverse 
  

   denticles, 
  but 
  the 
  upper 
  part 
  is 
  quite 
  smooth.
