  The 
  type 
  material 
  of 
  this 
  species 
  consists 
  of 
  23 
  specimens, 
  which 
  vary 
  in 
  size. 
  They 
  have 
  

   a 
  label, 
  "Swan 
  Neeah 
  Bay." 
  Although 
  Carpenter 
  described 
  the 
  umbilicus 
  as 
  wide, 
  that 
  char- 
  

   acter 
  varies 
  in 
  extent 
  among 
  the 
  syntypes. 
  !Most 
  have 
  a 
  large 
  umbilicus 
  with 
  a 
  sharp 
  margin, 
  

   but 
  on 
  one 
  specimen 
  the 
  umbilicus 
  is 
  closed. 
  The 
  umbilicus 
  is 
  not 
  consistent 
  with 
  age, 
  for 
  its 
  

   size 
  varies 
  on 
  individuals 
  of 
  similar 
  age 
  or 
  size. 
  The 
  spire 
  is 
  elevated 
  and 
  twisted. 
  The 
  young 
  

   specimens 
  have 
  a 
  shorter 
  and 
  blunter 
  spire. 
  Two 
  of 
  the 
  syntypes 
  are 
  figured 
  herein. 
  Both 
  

   of 
  those 
  specimens 
  are 
  umbilicate 
  (widely 
  sunken).

  Joshua 
  Baily 
  pointed 
  out 
  to 
  me 
  that 
  he 
  is 
  not 
  sure 
  that 
  tiiis 
  species 
  belongs 
  to 
  Littorina. 
  

   If 
  it 
  does 
  it 
  requires 
  a 
  new 
  name, 
  because 
  the 
  specific 
  name 
  Littorina 
  castanea 
  is 
  preoccupied 
  

   (see 
  synonymy). 
  If 
  it 
  is 
  not 
  a 
  Littorina, 
  the 
  species 
  need 
  not 
  be 
  renamed 
  unless 
  the 
  name 
  is 
  

   preoccupied 
  in 
  the 
  genus 
  in 
  which 
  it 
  is 
  reclassified. 
  The 
  species 
  should 
  not 
  be 
  renamed 
  until 
  

   the 
  generic 
  position 
  is 
  verified.
