  Because 
  there 
  seems 
  to 
  be 
  doubt 
  in 
  the 
  minds 
  of 
  workers 
  who 
  have 
  not 
  seen 
  Gray 
  (1821, 
  

   p.

  as 
  to 
  the 
  status 
  of 
  Sync 
  era 
  (supposed 
  to 
  be 
  proposed 
  there 
  as 
  a 
  genus) 
  the 
  following 
  

   is 
  a 
  copy 
  of 
  the 
  only 
  mention 
  the 
  writer 
  can 
  find 
  in 
  that 
  work 
  in 
  regard 
  to 
  Syncera. 
  

  

  "Nerita 
  Syncera 
  Hepatica, 
  N. 
  S. 
  — 
  The 
  animal 
  of 
  this 
  shell 
  differs 
  from 
  all 
  the 
  others 
  of 
  

   this 
  order, 
  by 
  the 
  eyes 
  appearing 
  to 
  be 
  at 
  the 
  ends 
  of 
  the 
  tentacula 
  ; 
  but, 
  I 
  believe, 
  that 
  they 
  

   are 
  placed 
  on 
  a 
  peduncle 
  as 
  long 
  as 
  the 
  tentacula, 
  and 
  the 
  peduncle 
  and 
  tentacula 
  are 
  sordered 
  

   [sic} 
  together. 
  . 
  . 
  ." 
  

  

  One 
  cannot 
  regard 
  this 
  name 
  as 
  a 
  valid 
  generic 
  proposal, 
  "^ 
  and 
  hence 
  the 
  name 
  Syncera 
  

   as 
  of 
  that 
  reference 
  would 
  not 
  have 
  priority 
  over 
  Assiminea.

  The

  should

  added 
  to 
  Oldroyd's 
  (1927) 
  copy

   (1866):

  the

  There 
  are 
  20 
  specimens 
  in 
  the 
  U. 
  S. 
  N'ational 
  Museum, 
  no. 
  126645. 
  which 
  are 
  segregated 
  

   as 
  Carpenter 
  "type" 
  material, 
  one 
  of 
  which 
  is 
  labelled 
  as 
  the 
  "lectotype" 
  of 
  Bartsch. 
  The 
  label 
  

   of 
  the 
  specimens 
  is 
  "Vancouver 
  Is. 
  Taylor." 
  That 
  specimen 
  labelled 
  lectotype 
  is 
  not 
  the 
  one 
  

   figured 
  as 
  "type" 
  by 
  Bartsch 
  (1920). 
  The 
  plate 
  explanation 
  defined 
  the 
  specimen 
  as 
  "type," 
  

   and 
  in 
  the 
  text 
  the 
  specimen 
  stated 
  to 
  be 
  described 
  and 
  figured 
  was 
  U. 
  S. 
  X'ational 
  Museum 
  

   no. 
  271483 
  and 
  came 
  from 
  San 
  Diego, 
  California. 
  This 
  specimen 
  could 
  be 
  selected 
  as 
  a 
  neo- 
  

   type 
  whereas 
  U. 
  S. 
  National 
  Museum 
  no. 
  126645 
  could 
  not. 
  The 
  type 
  locality 
  is 
  San 
  Diego, 
  as 
  

   stipulated 
  by 
  Carpenter, 
  and 
  therefore 
  a 
  Vancouver 
  shell 
  (no. 
  126645) 
  would 
  not 
  be 
  eligible.
