  The 
  Fauna

  Shales;

  Although 
  the 
  fauna 
  of 
  the 
  Miocene 
  shales 
  at 
  Florissant 
  has 
  

   been 
  much 
  studied 
  in 
  recent 
  years, 
  no 
  summary 
  has 
  been 
  pub- 
  

   lished 
  since 
  1906 
  (University 
  of 
  Colorado 
  Studies, 
  III, 
  pp. 
  163- 
  

   168). 
  It 
  is 
  not 
  possible 
  for 
  a 
  student 
  of 
  general 
  geology 
  or 
  

   palaeontology 
  to 
  ascertain 
  precisely 
  what 
  is 
  known 
  from 
  Floris- 
  

   sant 
  to-day 
  without 
  a 
  good 
  deal 
  of 
  bibliographical 
  research, 
  

   and 
  the 
  data 
  compiled 
  in 
  1906 
  are 
  no 
  longer 
  in 
  any 
  sense 
  ade- 
  

   quate. 
  I 
  therefore 
  present 
  a 
  concise 
  summary, 
  complete 
  to 
  

   the 
  present 
  date 
  (July 
  11), 
  but 
  including 
  only 
  described 
  and 
  

   published 
  species. 
  Families 
  or 
  groups 
  marked 
  with 
  an 
  asterisk 
  

   are 
  no 
  longer 
  found 
  in 
  North 
  America, 
  while 
  those 
  marked 
  

   with 
  a 
  dagger 
  are 
  wholly 
  extinct. 
  Genera 
  are 
  only 
  cited 
  when 
  

   they 
  are 
  extinct 
  and 
  do 
  not 
  fit 
  comfortably 
  into 
  the 
  recognized
