  The 
  shales 
  become 
  very 
  bituminous, 
  compact 
  and 
  heavy- 
  

   bedded, 
  not 
  changing 
  in 
  character 
  for 
  the 
  entire 
  thickness 
  to 
  

   797 
  feet. 
  The 
  fossils 
  are 
  few, 
  and 
  distributed 
  in 
  thin 
  beds 
  

   as 
  above. 
  The 
  character 
  of 
  the 
  rock 
  is 
  very 
  similar 
  to 
  that 
  

   in 
  the 
  more 
  bituminous 
  beds 
  of 
  the 
  Genesee. 
  

  

  Lunulicardium 
  fragile, 
  Liorhynchus 
  limitaris, 
  Chonetes 
  

   lepida, 
  O. 
  mucronata, 
  and 
  plant 
  remains 
  are 
  everywhere 
  

   abundant, 
  Goniatites 
  uniangularis, 
  Orthoceras 
  exile?, 
  Liop- 
  

   teria 
  Icevis, 
  Bhthonia 
  lirata 
  or 
  sp., 
  and 
  Amboccelia 
  umbonata 
  

   occur 
  frequently; 
  JPhacops 
  rana, 
  Cryphceus 
  Boothi, 
  Belter- 
  

   ophon 
  Leda> 
  Pleurotomaria 
  rugulata, 
  Nuculites 
  sp., 
  Modiella 
  

   pygmcea, 
  Cardiola 
  Boris 
  f, 
  Panenka 
  sp. 
  n. 
  ? 
  are 
  occasionally 
  

   found. 
  

  

  The 
  approximation 
  of 
  this 
  fauna 
  to 
  the 
  normal 
  fauna 
  the 
  

   black 
  fissile 
  Marcellus 
  shales 
  is 
  apparent 
  in 
  the 
  preponder- 
  

   ant 
  species.
