  "With

  it

  once 
  recognized

  the

  The

  is 
  much

  the 
  immature

  sent

  In

  difference, 
  however, 
  does 
  not 
  appear 
  to 
  be 
  specific."

  the

  to

  this

  "There 
  is 
  a 
  possibility 
  that 
  the 
  label 
  in 
  the 
  bottle 
  might 
  be 
  Rivers', 
  but 
  it 
  certainly 
  is 
  not 
  

   older 
  than 
  that, 
  and 
  might 
  be 
  younger." 
  

  

  This 
  species 
  was 
  founded 
  on 
  two 
  specimens, 
  one 
  from 
  tlie 
  Recent 
  and 
  one 
  from 
  the 
  

   Pleistocene. 
  Present 
  workers 
  seem 
  to 
  be 
  in 
  doubt 
  whether 
  the 
  species 
  occurs 
  in 
  the 
  living 
  

   fauna, 
  because 
  it 
  has 
  been 
  assumed 
  that 
  the 
  type 
  was 
  the 
  Pleistocene 
  shell. 
  

  

  However, 
  if 
  the 
  label 
  of 
  the 
  existing 
  type 
  is 
  correct, 
  the 
  holotype 
  (depending 
  on 
  whether 
  

   it 
  was 
  originally 
  selected 
  by 
  Carpenter) 
  came 
  from 
  Catalina 
  Island 
  and 
  is 
  a 
  Recent 
  shell. 
  

   Bormann 
  (1946), 
  in 
  the 
  explanation 
  of 
  the 
  figure 
  of 
  the 
  holotype, 
  defined 
  the 
  shell 
  from 
  the 
  

   "Pleistocene 
  of 
  Santa 
  Barbara," 
  but 
  that 
  is 
  a 
  confusion. 
  Apparently 
  the 
  Pleistocene 
  shell 
  is 
  

   not 
  available. 
  

  

  If 
  the 
  holotype 
  or 
  lectotype 
  is 
  established 
  on 
  the 
  Recent 
  species 
  and 
  that 
  is 
  the 
  locality 
  

   which 
  Carpenter 
  mentioned 
  first, 
  the 
  query 
  by 
  workers 
  as 
  to 
  the 
  presence 
  of 
  the 
  species 
  in 
  

   the 
  Recent 
  fauna 
  is 
  settled. 
  The 
  problem 
  would 
  then 
  be 
  to 
  identify 
  living 
  shells 
  which 
  may 
  

   be 
  at 
  present 
  classified 
  under 
  some 
  otiier 
  name. 
  If 
  the 
  Pleistocene 
  shells, 
  heretofore 
  called 
  

   T. 
  squaiiiulifera, 
  can 
  be 
  separated 
  from 
  the 
  holotype 
  of 
  T. 
  squamilifcra 
  as 
  a 
  distinct 
  species 
  

   or 
  subspecies, 
  the 
  Pleistocene 
  form 
  would 
  deserve 
  a 
  new 
  name.

   specimens

  had

  by 
  Arnold 
  have 
  been 
  

   assigned 
  to 
  this 
  species 
  by 
  Willett. 
  Woodring, 
  Bramlette, 
  and 
  Kew 
  agree 
  with 
  Willett 
  in 
  his 
  

   identification.
