   The 
  crude 
  figure 
  of 
  G. 
  larvcfformis 
  in 
  Blainville's 
  ' 
  Malacologie 
  ' 
  

   (1827), 
  pi. 
  87. 
  fig. 
  6, 
  is 
  probably 
  also 
  merely 
  a 
  young 
  specimen 
  of 
  

   the 
  same 
  species, 
  judging 
  from 
  the 
  sculpture 
  and 
  form 
  of 
  the 
  

   detached 
  valves. 
  In 
  the 
  drawing 
  of 
  them 
  m 
  situ 
  on 
  the 
  back 
  of 
  the 
  

   animal, 
  the 
  anterior 
  ones 
  are 
  rather 
  narrow. 
  The 
  valves 
  figured 
  

   by 
  Burrow 
  are 
  still 
  preserved 
  in 
  the 
  British 
  Museum 
  ; 
  but 
  I 
  caunot 
  

   find 
  the 
  dried 
  animals 
  or 
  that 
  in 
  spirit 
  which 
  he 
  mentions. 
  

  

  Blainville's 
  figure 
  represents 
  the 
  mantle 
  as 
  clothed 
  with 
  compara- 
  

   tively 
  longish 
  spines, 
  and 
  the 
  gills 
  extend 
  nearly 
  halfway 
  up 
  the 
  side 
  

   of 
  the 
  foot. 
  In 
  G. 
  burrowi, 
  on 
  the 
  contrary, 
  the 
  gills 
  are 
  very 
  short, 
  

   do 
  not 
  occupy 
  a 
  third 
  of 
  the 
  length, 
  and 
  are 
  only 
  22 
  in 
  number. 
  

  

  G. 
  oculatus 
  of 
  Quoy 
  and 
  Gaimard 
  I 
  believe 
  to 
  be 
  a 
  young 
  state 
  

   of 
  their 
  G. 
  fasciatus. 
  In 
  the 
  British 
  Museum 
  there 
  are 
  some 
  small 
  

   specimens 
  of 
  this 
  species 
  which 
  answer 
  very 
  closely 
  to 
  the 
  descrip- 
  

   tion 
  ; 
  they 
  have 
  the 
  two 
  dark 
  bands 
  meeting 
  over 
  the 
  back, 
  the 
  

   posterior 
  valves 
  narrow 
  and 
  separated, 
  and 
  the 
  three 
  anterior 
  ones 
  

   pale 
  greenish 
  and 
  surrounded 
  by 
  a 
  border 
  of 
  short 
  black 
  spines 
  

   with 
  a 
  pale 
  zone 
  outside 
  it. 
  The 
  other 
  spines 
  on 
  the 
  mantle 
  in 
  the 
  

   smallest 
  specimen 
  are 
  a 
  trifle 
  longer 
  than 
  usual 
  and 
  very 
  closely 
  

   packed. 
  The 
  gills 
  are 
  said 
  to 
  number 
  twenty 
  on 
  each 
  side 
  in 
  

   G. 
  oculatus, 
  being 
  three 
  less 
  than 
  in 
  G. 
  fasciatus, 
  a 
  discrepancy 
  

   accounted 
  for 
  by 
  age 
  ; 
  for 
  in 
  adult 
  specimens 
  of 
  C. 
  striatus 
  I 
  find 
  a 
  

   few 
  more 
  than 
  in 
  the 
  young.
