  The 
  principal 
  ridges 
  which 
  support 
  the 
  largest 
  spines 
  are 
  about 
  

   twelve 
  in 
  number 
  on 
  the 
  upper 
  valve, 
  pale 
  or 
  yellowish 
  between 
  the 
  

   spines, 
  at 
  the 
  base 
  of 
  which 
  they 
  are 
  stained 
  with 
  a 
  dark 
  san- 
  

   guineous 
  colour. 
  The 
  interior 
  of 
  the 
  valves 
  is 
  margined 
  with 
  pur- 
  

   plish 
  brown, 
  and 
  the 
  straight 
  hinge-line 
  is 
  fiuely 
  striated 
  within 
  

   transversely 
  ; 
  the 
  flat 
  hinge-area 
  of 
  the 
  lower 
  valve 
  is 
  also 
  fiuely 
  

   striated 
  across.

  The 
  description 
  of 
  this 
  species 
  given 
  by 
  Sowerby 
  is 
  very 
  insuffi- 
  

   cient, 
  and 
  his 
  locality, 
  " 
  Gulf 
  of 
  California," 
  incorrect. 
  He 
  describes 
  

   the 
  number 
  of 
  largecostfe 
  as 
  four 
  ; 
  but 
  as 
  a 
  rule 
  there 
  are 
  five, 
  which 
  

   even 
  appear 
  in 
  his 
  own 
  figure. 
  

  

  In 
  the 
  lower 
  or 
  attached 
  valve 
  the 
  number 
  of 
  large 
  spine-bearing 
  

   ridges 
  in 
  the 
  three 
  specimens 
  before 
  me 
  is 
  seven 
  ; 
  these 
  spines 
  are 
  

   generally 
  straighter 
  than 
  those 
  on 
  the 
  upper 
  valve, 
  and 
  channelled 
  

   on 
  the 
  uppersidc. 
  Sowcrby's 
  figure 
  exaggerates 
  the 
  wavy 
  character 
  

   and 
  breadth 
  of 
  the 
  upper 
  spines. 
  

  

  The 
  surface 
  of 
  the 
  valves 
  and 
  the 
  hinge-area 
  agree 
  with 
  Crosse's 
  

   description 
  of 
  the 
  variety 
  ivrightlanas, 
  which 
  has 
  the 
  spines 
  on 
  the 
  

   upper 
  valve 
  straighter, 
  and 
  less 
  spreading 
  at 
  the 
  extremities. 
  The 
  

   single 
  specimen 
  dredged 
  by 
  Dr. 
  Coppinger 
  has 
  the 
  spines 
  of 
  a 
  pinkish- 
  

   buff 
  colour, 
  whilst 
  those 
  in 
  the 
  type 
  are 
  pure 
  white.

  It 
  is 
  not 
  surprising 
  that 
  M. 
  Bcrnardi 
  did 
  not 
  recognize 
  his 
  shell 
  

   in 
  F.

  considering 
  how 
  inadequate 
  a 
  description 
  is
