  The 
  holotype 
  of 
  "O. 
  spongiosa" 
  is 
  in 
  tlie 
  U. 
  S. 
  National 
  Museum. 
  It 
  is 
  labelled 
  "type

  There 
  are 
  microscopic 
  punctations 
  over 
  the 
  whole 
  shell. 
  The 
  apex 
  on 
  the 
  holotype 
  is 
  gone. 
  

   On 
  the 
  upper 
  three 
  whorls 
  there 
  are 
  longitudinal 
  ribs 
  which 
  extend 
  the 
  length 
  of 
  the 
  whorl 
  ; 
  

   on 
  the 
  next 
  whorl 
  the 
  ribs 
  do 
  not 
  extend 
  the 
  full 
  length 
  of 
  the 
  whorl, 
  and 
  they 
  become 
  less 
  

   conspicuous 
  in 
  length 
  on 
  the 
  lower 
  whorls. 
  The 
  ribs 
  have 
  the 
  appearance 
  of 
  being 
  tucked 
  in 
  

   at 
  the 
  suture.
