  the 
  species

  have, 
  so 
  far 
  as 
  observed, 
  not 
  shown

   of

  We 
  shall 
  not 
  be 
  surprised 
  when 
  sufficient 
  material 
  shall 
  have 
  

   been 
  collected 
  from 
  the 
  Lower 
  Lignitic 
  if 
  this 
  varietal 
  form 
  

   proves 
  to 
  be 
  different 
  enough 
  from 
  the 
  original 
  "Red 
  bluff" 
  

   type 
  to 
  warrant 
  a 
  new 
  specific 
  name. 
  Our 
  present 
  specimens 
  

   though 
  numerous 
  are 
  all 
  too 
  fragmentary 
  to 
  use 
  as 
  types.

  This 
  is 
  a 
  characteristic 
  Lignitic 
  Eocene 
  species. 
  It 
  occurs 
  in 
  

   abundance 
  at 
  Woods 
  bluff 
  and 
  lower 
  localities 
  in 
  Alabama. 
  I 
  

   have 
  already 
  recorded 
  (see 
  above 
  reference) 
  it 
  from 
  Sabinetown, 
  

   Texas. 
  We 
  have 
  obtained 
  more 
  material 
  from 
  the 
  same 
  locality.
