  Dall 
  and 
  Bartsch 
  (1907) 
  gave 
  and 
  repeated 
  (1909) 
  a 
  complete 
  discussion 
  of 
  the 
  shell 
  

   of 
  this 
  species 
  and 
  figured 
  the 
  lectotype. 
  The 
  specimen 
  (no. 
  4493b) 
  is 
  labelled 
  "Puget 
  

   Soirnd" 
  and 
  "Santa 
  Barbara." 
  Dall 
  and 
  Bartsch 
  suggested 
  tliat 
  the 
  specimen 
  came 
  from 
  

   Puget 
  Sound, 
  as 
  the 
  species 
  has 
  not 
  been 
  reported 
  south 
  of 
  there 
  since 
  Carpenter's 
  and 
  

   Cooper's 
  time. 
  Because 
  of 
  the 
  discrepancy 
  in 
  the 
  label, 
  the 
  writer 
  uses 
  the 
  term 
  lectotype 
  

   and 
  follows 
  Dall 
  and 
  Bartsch 
  in 
  choosing 
  Puget 
  Sound 
  as 
  the 
  proper 
  locality. 
  Dall 
  and 
  

   Bartsch 
  referred 
  (1907; 
  1909) 
  to 
  the 
  specimen 
  mentioned 
  as 
  "type," 
  but 
  it 
  is 
  listed 
  by 
  

   Bartsch 
  (1912) 
  as 
  specimen. 
  

  

  There 
  is 
  still 
  uncertainty, 
  however, 
  regarding 
  this 
  species, 
  because 
  Carpenter 
  (1864b, 
  

   p. 
  531, 
  603, 
  659; 
  1865g, 
  p. 
  148) 
  made 
  particular 
  mention 
  that 
  the 
  species 
  was 
  found 
  by 
  Col. 
  

   Jewett 
  at 
  Santa 
  Barbara.
