  The

  resemble 
  

   small 
  Litorinae." 
  [Carpenter, 
  1864, 
  p. 
  428] 
  

  

  The 
  type 
  material 
  consists 
  of 
  nine 
  specimens 
  labelled 
  "Type 
  Neeah 
  Bay 
  Swan." 
  The 
  body 
  

   whorl 
  of 
  the 
  shells 
  has 
  a 
  sharp 
  basal 
  margin. 
  The 
  umbilicus 
  is 
  long 
  ; 
  it 
  has 
  a 
  sharp 
  margin 
  

   above 
  and 
  flares 
  below. 
  The 
  surface 
  is 
  smooth 
  with 
  faint 
  microscopic 
  striae 
  in 
  some 
  places. 
  

   The 
  largest 
  specimen 
  is 
  figured 
  herein. 
  

  

  In 
  comparing 
  the 
  illustrations 
  of 
  the 
  various 
  types 
  of 
  the 
  Carpenter 
  named 
  forms 
  the 
  

   dimensions 
  of 
  each 
  should 
  be 
  borne 
  in 
  mind. 
  The 
  photograph 
  of 
  L. 
  compacta 
  is 
  enlarged 
  to 
  

   greater 
  magnification 
  than 
  the 
  others, 
  which 
  are 
  larger 
  in 
  actual 
  measurements. 
  

  

  L. 
  compacta 
  has 
  the 
  whorls 
  carinated 
  stronger 
  than 
  any 
  of 
  the 
  other 
  Carpenter 
  Lacunae 
  

   shells, 
  as 
  well 
  as 
  the 
  illustrations 
  of 
  L. 
  carinata 
  Gould 
  or 
  L. 
  solidula 
  Loven. 
  

  

  /.. 
  compacta 
  has 
  been 
  included 
  under 
  L. 
  divaricata 
  (Fabricius) 
  ^^ 
  by 
  Tryon, 
  probably 
  

   by 
  Dall 
  and 
  Oldroyd, 
  as 
  synonymous 
  with 
  L. 
  solidula 
  carinata 
  Gould 
  by 
  Strong, 
  and 
  L. 
  

   divaricata 
  carinata 
  Gould 
  by 
  Grant 
  and 
  Gale. 
  Carpenter 
  regarded 
  L. 
  solidula 
  Loven 
  and 
  L. 
  

   carinata 
  as 
  synonymous 
  as 
  did 
  Dall 
  (1925, 
  p. 
  18, 
  PI. 
  34, 
  fig. 
  2, 
  L. 
  solidula 
  Loven). 
  Grant 
  and 
  

   Gale 
  maintained 
  each 
  as 
  a 
  distinct 
  subspecies. 
  Woodring, 
  Bramlette, 
  and 
  Kew 
  (1948) 
  believed 
  

   L. 
  porrecta 
  and 
  L. 
  carinata 
  equal. 
  

  

  L. 
  divaricatus 
  (Fabricius) 
  cannot 
  be 
  used. 
  According 
  to 
  English 
  writers 
  it 
  is 
  equivalent 
  

   to 
  L. 
  vincta 
  Montagu.
