  The 
  holotype 
  is 
  a 
  shell 
  with 
  an 
  operculum. 
  The 
  label 
  is 
  "Neeah 
  Bay 
  J. 
  G. 
  Swan 
  type." 
  

  

  The 
  shell 
  is 
  blackish, 
  partly 
  smooth, 
  smoothest 
  over 
  the 
  spire 
  and 
  lower 
  body 
  whorl 
  ; 
  

   strong 
  sutural 
  rib 
  present 
  just 
  below 
  the 
  suture; 
  spiral 
  ribs 
  on 
  the 
  upper 
  body 
  whorl; 
  apex 
  

   worn, 
  blunt, 
  base 
  with 
  spiral 
  ribs 
  ; 
  posterior 
  groove 
  on 
  the 
  labrum, 
  large 
  tooth 
  on 
  the 
  labium 
  ; 
  

   umbilicate 
  ; 
  operculum 
  horny, 
  circular, 
  spiraling, 
  and 
  thin. 
  

  

  Dall 
  (1892) 
  figured 
  the 
  basal 
  area 
  of 
  the 
  holotype. 
  

  

  Some 
  authors 
  have 
  expressed 
  doubt 
  as 
  to 
  the 
  value 
  of 
  this 
  subspecies. 
  Burch 
  stated 
  that 
  

   certain 
  colonies 
  seem 
  to 
  be 
  umbilicated 
  and 
  others 
  not.
