  There 
  is 
  some 
  question 
  as 
  to 
  the 
  true 
  type 
  of 
  this 
  species. 
  The 
  first 
  specimen 
  which 
  Car- 
  

   penter 
  noted 
  (1864b, 
  p. 
  602) 
  was 
  a 
  specimen 
  collected 
  by 
  Dr. 
  Kennerley 
  from 
  Puget 
  Sound. 
  

   There 
  is 
  a 
  question 
  whether 
  that 
  shell 
  is 
  the 
  one 
  now 
  labelled 
  type 
  in 
  the 
  U. 
  S. 
  National 
  

   Museum 
  (no. 
  5249) 
  and 
  figured 
  by 
  Dall 
  (1901b). 
  That 
  specimen 
  is 
  labelled, 
  "Dr. 
  Kennerly 
  

   [sic] 
  Puget 
  Sound." 
  There 
  are, 
  however, 
  in 
  the 
  Redpath 
  Museum, 
  two 
  broken 
  specimens 
  la- 
  

   belled 
  "type. 
  Dr. 
  Kennerly 
  [sic] 
  Puget 
  Sound." 
  

  

  Carpenter 
  did 
  not 
  give 
  a 
  complete 
  description 
  of 
  this 
  form, 
  but 
  with 
  the 
  few 
  descriptive 
  

   words 
  by 
  Carpenter 
  (see 
  above) 
  the 
  locality 
  is 
  stated 
  to 
  be 
  "? 
  Catalina 
  Island." 
  

  

  The 
  Puget 
  Sound 
  specimens 
  are 
  not 
  the 
  primary 
  types, 
  but 
  the 
  questionable 
  Catalina 
  Is- 
  

   land 
  specimen 
  noted 
  by 
  Carpenter 
  has 
  not 
  been 
  found. 
  The 
  first 
  locality 
  mentioned 
  (1864b, 
  

   p. 
  602) 
  in 
  connection 
  with 
  the 
  specific 
  name 
  was 
  Puget 
  Sound. 
  Therefore, 
  it 
  would 
  seem 
  

   logical 
  to 
  designate 
  as 
  tlie 
  lectotype 
  a 
  specimen 
  which 
  had 
  been 
  labelled 
  by 
  Carpenter 
  and 
  

   collected 
  from 
  Puget 
  Sound 
  by 
  the 
  original 
  discoverer. 
  Dr. 
  Kennerley. 
  In 
  the 
  first 
  mention 
  

   of 
  the 
  species. 
  Carpenter 
  wrote, 
  "one 
  living 
  sp." 
  Hence, 
  there 
  would 
  be 
  a 
  question 
  as 
  to 
  

   which 
  is 
  the 
  authentic 
  original 
  shell, 
  one 
  of 
  those 
  of 
  the 
  U. 
  S. 
  National 
  Museum 
  or 
  of 
  the 
  

   Redpath 
  Museum. 
  Since 
  the 
  Redpath 
  Museum 
  specimens 
  are 
  broken, 
  the 
  writer 
  designates 
  

   the 
  specimen 
  figured 
  by 
  Dall 
  (1901), 
  U. 
  S. 
  National 
  Museum, 
  no. 
  5249, 
  as 
  the 
  lectotype 
  of 
  

   the 
  species. 
  There 
  are 
  three 
  specimens 
  under 
  no. 
  5249. 
  Dall 
  (1901b 
  explanation 
  of 
  pi. 
  XL, 
  

   fig. 
  2) 
  refers 
  to 
  the 
  specimen 
  as 
  the 
  type. 
  

  

  ^-Opsis, 
  Greek, 
  feminine 
  gender. 
  Following 
  Dall, 
  tliis 
  specific 
  name 
  has 
  been 
  incorrectly 
  

   written 
  in 
  the 
  masculine 
  when 
  written 
  with 
  Axinopsis. 
  Probably 
  Carpenter 
  when 
  he 
  stated 
  

   "epidermis 
  silken" 
  and 
  named 
  the 
  species 
  scrricatus 
  [sic] 
  meant 
  the 
  Latin 
  word 
  sericatus 
  

   ("clothed 
  in 
  silken 
  garments"). 
  Hence, 
  the 
  original 
  spelling 
  of 
  the 
  specific 
  name 
  could 
  be 
  con- 
  

   sidered 
  a 
  lapsus 
  and 
  the 
  name 
  be 
  corrected 
  to 
  sericatus 
  as 
  Dall 
  did 
  in 
  1921. 
  Tlie 
  reasoning 
  op- 
  

   posed 
  to 
  this 
  change 
  is 
  that 
  Carpenter 
  consistently 
  spelled 
  the 
  specific 
  name 
  with 
  two 
  r's, 
  and 
  

   Car])enter 
  was 
  also 
  a 
  Latin 
  student.
