  The 
  type 
  material 
  is 
  in 
  the 
  U. 
  S. 
  National 
  Museum 
  and 
  consists 
  of 
  five 
  specimens 
  (one 
  a 
  

   fragment 
  of 
  a 
  body 
  whorl). 
  The 
  label 
  reads 
  "Neeah 
  Bay 
  J. 
  G. 
  Swan." 
  The 
  specimen 
  figured 
  

   by 
  Strong 
  (1930) 
  as 
  type 
  is 
  apparently 
  the 
  same 
  specimen 
  as 
  figured 
  herein 
  (PI. 
  20, 
  fig. 
  23). 
  

   Another 
  specimen 
  of 
  the 
  type 
  group 
  is 
  figured 
  herein 
  (PI. 
  20, 
  fig. 
  24). 
  The 
  apices 
  of 
  all 
  the 
  

   specimens 
  are 
  gone. 
  All 
  specimens 
  are 
  white 
  and 
  slightly 
  worn. 
  The 
  varices 
  vary 
  respectively, 
  

   15 
  in 
  the 
  largest 
  specimen, 
  10 
  varices 
  on 
  the 
  next 
  largest, 
  14 
  varices 
  on 
  the 
  next, 
  and 
  11 
  on 
  the 
  

   smallest 
  individual. 
  Therefore, 
  the 
  number 
  of 
  varices 
  might 
  vary 
  from 
  10 
  to 
  15. 
  if 
  all 
  the 
  

   specimens 
  are 
  retained 
  in 
  the 
  species. 
  The 
  maximum 
  number 
  is 
  the 
  same 
  as 
  in 
  Carpenter.
