  Conclusion. 
  

  

  The 
  facts 
  described 
  in 
  the 
  preceding 
  paper, 
  it 
  is 
  believed, 
  

   satisfactorily 
  establish 
  the 
  following 
  points. 
  

  

  1. 
  There 
  is 
  a 
  succession 
  of 
  faunas 
  in 
  the 
  limestones 
  about 
  

   Springfield. 
  

  

  2. 
  The 
  faunas 
  of 
  the 
  lower 
  part 
  of 
  the 
  section 
  may 
  be 
  corre- 
  

   lated 
  with 
  the 
  Burlington 
  faunas 
  of 
  Iowa, 
  and 
  those 
  of 
  the 
  

   upper 
  part 
  with 
  the 
  Keokuk 
  faunas. 
  

  

  3. 
  The 
  whole 
  series 
  of 
  sub-faunas 
  is 
  continuous, 
  and 
  the 
  

   whole 
  series 
  of 
  rocks 
  should 
  be 
  designated 
  by 
  a 
  single 
  name. 
  

   The 
  Osage 
  Group* 
  is 
  the 
  earliest 
  name 
  suggested 
  for 
  this 
  series 
  

   of 
  strata.
