  The 
  holotype 
  of 
  this 
  species 
  is 
  in 
  the 
  United 
  States 
  N^ational 
  Museum. 
  Dall 
  did 
  not 
  state 
  

   that 
  the 
  illustration 
  which 
  he 
  included 
  (1921) 
  was 
  of 
  the 
  type. 
  The 
  dimensions 
  are 
  the 
  same, 
  

   but 
  the 
  drawing 
  presents 
  a 
  different 
  aspect 
  than 
  that 
  of 
  the 
  actual 
  specimen 
  or 
  a 
  photograph 
  

   of 
  the 
  same. 
  Dall's 
  drawing 
  has 
  an 
  additional 
  row 
  of 
  spiral 
  ribs, 
  and 
  the 
  nodes 
  appear 
  less 
  

   sharp 
  than 
  they 
  are. 
  The 
  specimen 
  has 
  intervening 
  fine 
  spiral 
  threads 
  not 
  shown 
  on 
  Dall's 
  

   drawing 
  or 
  on 
  the 
  photograph 
  of 
  the 
  holotype 
  herein 
  included. 
  

  

  The 
  Dall 
  drawing 
  has 
  an 
  aspect 
  of 
  whorl
