  We 
  have 
  but 
  a 
  small, 
  fragmentary 
  specimen 
  of 
  this 
  species 
  

   from 
  Pendleton, 
  Texas, 
  but 
  its 
  markings 
  are 
  so 
  peculiar 
  that 
  its 
  

   identification 
  is 
  simple 
  and 
  certain.

  Two 
  varieties 
  of 
  this 
  species 
  are 
  present 
  in 
  the 
  lyignitic 
  of 
  

   Louisiana. 
  One, 
  the 
  form 
  figured, 
  is 
  rather 
  characteristic 
  of 
  the 
  

   Lower 
  Lignitic 
  and 
  Midway 
  ; 
  another 
  with 
  much 
  callositj' 
  about 
  

   the 
  upper 
  portions 
  of 
  the 
  volutions 
  is 
  not 
  uncommon 
  in 
  the 
  form 
  

   of 
  casts.
