  DESCRIBED

  CARPENTER 
  

  

  hence 
  his 
  name 
  is 
  no 
  more 
  valid 
  tlian 
  tlic- 
  initial 
  remarks. 
  There 
  is 
  also 
  a 
  confusion 
  in 
  the 
  

   spelling 
  which 
  makes 
  further 
  confusion 
  in 
  the 
  use 
  of 
  the 
  name. 
  

  

  No 
  types 
  exist 
  for 
  the 
  name. 
  If 
  it 
  is 
  to 
  acquire 
  proper 
  status 
  it 
  must 
  be 
  described 
  by 
  some 
  

   author 
  subsequent 
  to 
  those 
  already 
  credited. 
  It 
  is 
  assumed 
  by 
  workers 
  to 
  be 
  synonymous 
  

   with 
  A. 
  pelta.

  22,2,;

  p. 
  288; 
  Pilsbry,

   p. 
  233 
  was 
  described 
  as 
  from 
  "Monterey." 
  

  

  Tomlin, 
  (1925, 
  p. 
  121) 
  identified 
  the 
  syntypes 
  of 
  the 
  species, 
  which 
  are 
  in 
  the 
  British 
  

   Museum, 
  as 
  "Cellana

  1946, 
  PI. 
  1,

  The 
  name 
  can, 
  therefore, 
  be 
  authentically 
  eliminated 
  from 
  the

  of
