  Dall 
  discussed 
  this 
  species 
  in 
  detail 
  (1891) 
  and 
  figured 
  the 
  type 
  (a 
  young 
  shell) 
  and 
  an 
  

   adult 
  individual 
  from 
  San

  later 
  (1902) 
  repeated 
  his 
  earlier 
  statements.

  "This 
  specimen 
  still 
  has 
  the 
  operculum 
  with 
  it. 
  Otlierwise 
  the 
  two 
  are 
  in 
  equally 
  good 
  

   condition. 
  Perhaps 
  12572 
  should 
  be 
  designated 
  as 
  the 
  Lectotype." 
  

  

  In 
  referring 
  to 
  the 
  specimen 
  at 
  the 
  University 
  of 
  California 
  as 
  the 
  type 
  which 
  he 
  figured 
  

   (1892), 
  Dall 
  described 
  the 
  specimen 
  as 
  containing 
  the 
  operculum. 
  The 
  writer 
  therefore 
  iden- 
  

   tifies 
  no. 
  12572, 
  University 
  California 
  Museum 
  Paleontology 
  as 
  that 
  shell 
  and 
  selects 
  that 
  

   specimen 
  as 
  the 
  lectotype 
  of 
  the 
  species. 
  

  

  A 
  specimen 
  in 
  the 
  U. 
  S. 
  National 
  Museum, 
  no. 
  11839, 
  is 
  labelled, 
  "Catalina 
  Id. 
  Cooper 
  

   Type 
  fig'd." 
  The 
  shell 
  is 
  10 
  mm. 
  length 
  and 
  6 
  mm. 
  greatest 
  diameter 
  ; 
  hence 
  it 
  is 
  a 
  young 
  

   shell 
  about 
  the 
  size 
  of 
  the 
  lectotype. 
  From 
  the 
  original 
  description 
  (1866) 
  there 
  could 
  be 
  

   syntypes, 
  all 
  from 
  Catalina 
  Island 
  and 
  of 
  the 
  same 
  size. 
  If 
  the 
  specimen 
  in 
  the 
  U. 
  S. 
  National 
  

   Museum 
  was 
  indicated 
  as 
  type 
  in 
  Dall's 
  day, 
  it 
  is 
  odd 
  that 
  Dall 
  did 
  not 
  describe 
  that 
  speci- 
  

   men 
  and 
  figure 
  it 
  instead 
  of 
  going 
  so 
  far 
  afield. 
  As 
  the 
  labels 
  stand 
  it 
  can 
  be 
  regarded 
  as 
  a 
  

   syntype 
  and 
  a 
  lectotype 
  can 
  be 
  chosen 
  from 
  the 
  three 
  syntypes, 
  which 
  is 
  what 
  the 
  writer 
  has 
  

   done 
  above. 
  

  

  Oldroyd 
  figured 
  both 
  University 
  California 
  syntypes. 
  The 
  U. 
  S. 
  National 
  Museum 
  

   "syntype" 
  apparently 
  has 
  not 
  been 
  figured, 
  regardless 
  of 
  the 
  label. 
  

  

  This 
  species 
  does 
  not 
  seem 
  to 
  be 
  typical 
  Trophonopsis 
  [Boreotrophon].
