  is 
  almost 
  entirely 
  composed 
  

   of 
  Diplograptidae

   bears 
  in

  Bpeciea 
  a 
  decidedly 
  yonnger 
  charai 
  

   than 
  the 
  Normans 
  kill 
  fauna, 
  as 
  becomes 
  apparent 
  by 
  a 
  compari- 
  

   with 
  the 
  vertical 
  range 
  of 
  the 
  same 
  forms 
  in 
  (Sweden 
  and 
  

   at 
  Britain. 
  In

  to 
  the

  of 
  Ids 
  death 
  Hall 
  insisted 
  on 
  

   the 
  different 
  I 
  the 
  two 
  faunas. 
  ;l 
  s 
  the 
  writer 
  can 
  assert 
  by 
  

  

  personal 
  information 
  from 
  the 
  genial 
  paleontologist. 
  

  

  Hie 
  concurrence 
  of 
  the 
  two 
  graptolites 
  will 
  indicate 
  hardly 
  

   more 
  than 
  the 
  Middle 
  Champlainic

  Mohawkian 
  age 
  of 
  

   the 
  Normans 
  kill

  The 
  Cohoea

  which 
  Whitfield 
  believes 
  to 
  be 
  of 
  equal 
  age 
  

  

  with
