  "This

  differs 
  from 
  the 
  common 
  Margarita 
  of 
  the 
  Vancouver 
  district 
  (M. 
  t>upil!a 
  

   Gld. 
  = 
  caUiostoma 
  A. 
  Ad.), 
  in 
  its 
  mucli 
  deeper 
  and 
  salmon-tinted 
  hue; 
  its 
  finer 
  sculpture, 
  

   absence 
  of 
  decussation, 
  and 
  want 
  of 
  distant 
  lirae 
  round 
  the 
  umbilicus. 
  From 
  the 
  Norwegian 
  

   specimens 
  of 
  .1/. 
  undulata 
  it 
  is 
  known 
  by 
  the 
  absence 
  of 
  sutural 
  waves, 
  and 
  by 
  the 
  finer 
  basal 
  

   riblets, 
  of 
  which 
  the 
  interstices 
  are 
  minutely 
  sculptured 
  across. 
  The 
  operculum 
  differs 
  from 
  

   both, 
  in 
  its 
  great 
  thinness 
  and 
  smoothness. 
  Additional 
  specimens 
  may 
  better 
  display 
  its 
  true 
  

   relations."*

  Dall 
  originally 
  described 
  Lirularia 
  as 
  a 
  section 
  of 
  the 
  subgenus 
  Pupillaria. 
  In 
  1921 
  he 
  

   raised 
  the 
  group 
  to 
  subgeneric 
  rank. 
  This 
  classification 
  has 
  been 
  followed 
  by 
  authors 
  but 
  ap- 
  

   parently 
  not 
  with 
  conviction 
  that 
  it 
  is 
  correct 
  (Grant 
  and 
  Gale, 
  1931, 
  p. 
  839; 
  Burch, 
  1946, 
  no. 
  

   58, 
  p. 
  8). 
  In 
  analyzing 
  such 
  segregation 
  as 
  M. 
  rhodia 
  Dall 
  in 
  Pupillaria 
  and 
  M. 
  inflatulus 
  Dall 
  

   in 
  Lirularia, 
  the 
  writer 
  does 
  not 
  see 
  justification 
  for 
  the 
  importance 
  of 
  subgeneric 
  rank 
  of 
  

   Lirularia. 
  The 
  writer 
  therefore 
  returns 
  to 
  its 
  use 
  as 
  a 
  section 
  and 
  is 
  aware 
  that 
  sections 
  have 
  

   no 
  nomenclatorial 
  status 
  in 
  the 
  International 
  Rules 
  of 
  Zoological 
  Nomenclature, 
  except 
  that 
  

   the 
  International 
  Commission 
  agreed 
  to 
  recommend 
  that 
  such 
  groups 
  be 
  treated 
  as 
  having 
  

   subgeneric 
  status.

  The

  should 
  be 
  added

  The 
  syntypes 
  consist 
  of 
  three 
  specimens 
  ; 
  according 
  to 
  their 
  label 
  they 
  are 
  the 
  specimens 
  

   Rowell 
  got 
  on 
  the 
  Haliotis 
  in 
  Lower 
  California. 
  The 
  Neah 
  Bay 
  specimen 
  is 
  apparently 
  not 
  

   available.

  The 
  largest 
  of 
  the 
  syntypes 
  was 
  figured 
  by 
  Dall 
  (1921). 
  The 
  measurement 
  given 
  by 
  Dall 
  

   (explanation 
  pi. 
  17, 
  fig. 
  9) 
  is 
  1 
  mm. 
  larger 
  than 
  the 
  writer's 
  measurement. 
  The 
  specimens 
  

   have 
  a 
  large 
  umbilicus. 
  Numerous 
  spiral 
  ribs 
  are 
  present 
  over 
  the 
  whorls, 
  largest 
  on 
  the 
  pos- 
  

   terior 
  part 
  of 
  the 
  whorls.
