  The 
  holotype 
  has 
  been 
  drilled 
  vertically 
  by 
  some 
  animal 
  which 
  left 
  a 
  circular 
  opening 
  in 
  

   the 
  posterior 
  columellar 
  area 
  under 
  the 
  overhang 
  of 
  the 
  whorl. 
  It 
  is 
  visible 
  in 
  the 
  photograph 
  

   and 
  appears 
  like 
  a 
  misplaced 
  umbilicus. 
  

  

  Burch 
  (1945 
  no. 
  55, 
  p. 
  24) 
  suggested 
  that 
  the 
  listing 
  of 
  Diala 
  marmorca 
  by 
  Baker 
  (1902, 
  

   p. 
  41) 
  is 
  a 
  misidentification, 
  as 
  he 
  believed 
  D. 
  acuta 
  is 
  the 
  southern 
  form, 
  although 
  in 
  the 
  

   range 
  of 
  B. 
  marmorea, 
  he 
  extended 
  the 
  boundary 
  to 
  Lower 
  California. 
  

  

  A 
  comparison 
  of 
  the 
  illustrations 
  herein 
  of 
  the 
  two 
  above-mentioned 
  species 
  reveals 
  the 
  

   difference 
  in 
  the 
  angulation 
  of 
  the 
  body 
  whorl 
  of 
  the 
  forms.

  Three 
  specimens 
  in 
  the 
  U. 
  S. 
  Nat. 
  Museum 
  (no. 
  32363) 
  are 
  now 
  laljelled 
  "type" 
  and 
  stated 
  

   to 
  be 
  figured 
  by 
  Bartsch. 
  One 
  label 
  has 
  "P.P.C." 
  with 
  no 
  locality. 
  The 
  three 
  specimens 
  are 
  

   each 
  figured 
  herein. 
  They 
  are 
  not 
  labelled 
  "type" 
  in 
  the 
  catalogue, 
  (U. 
  S. 
  National 
  Museum), 
  

   and 
  they 
  do 
  not 
  correspond 
  to 
  Bartsch's 
  statement 
  (1920, 
  p. 
  170) 
  as 
  to 
  type. 
  

  

  Bartsch 
  (1920) 
  explained 
  in 
  the 
  text 
  concerning 
  the 
  species 
  that 
  the 
  specimen 
  figured 
  is 
  

   one 
  of 
  147 
  of 
  no. 
  56446, 
  and 
  that 
  the 
  shells 
  came 
  from 
  San 
  Diego. 
  In 
  the 
  explanation 
  of 
  the 
  

   figure 
  in 
  the 
  same 
  article 
  (and 
  in 
  the 
  column 
  on 
  p. 
  170), 
  the 
  figure 
  is 
  labelled 
  "type." 
  

  

  Since 
  apparently 
  a 
  holotype 
  selected 
  by 
  Carpenter 
  is 
  not 
  available, 
  the 
  specimen 
  figured 
  by 
  

   Bartsch 
  could 
  be 
  designated 
  as 
  the 
  neotype. 
  This 
  specimen 
  is 
  not 
  a 
  lectotype 
  in 
  the 
  strict 
  

   sense, 
  for 
  material 
  from 
  which 
  it 
  would 
  be 
  selected 
  is 
  not 
  in 
  the 
  original 
  collection.
