  After 
  about 
  34 
  feet 
  of 
  covered 
  rocks 
  an 
  artificial 
  ex- 
  

   posure 
  of 
  greenish 
  argillaceous 
  shales 
  was 
  shown 
  in 
  an 
  excava- 
  

   tion 
  for 
  a 
  cellar. 
  These 
  shales 
  are 
  fossiliferous, 
  the 
  following 
  

   species 
  having 
  been 
  obtained 
  : 
  

  

  1 
  Rhynchonella 
  sp.

  2 
  Paracyclas 
  lirata

  For 
  99 
  feet 
  above 
  the 
  greenish 
  shales 
  of 
  D

  the 
  rocks 
  

   are 
  mainly 
  covered; 
  but 
  there 
  are 
  loose, 
  angular 
  slabs 
  of 
  arenace- 
  

   ous 
  shales 
  to 
  thin 
  sandstones 
  on 
  the 
  surface 
  that 
  apparently 
  came 
  

   from 
  this 
  part 
  of 
  the 
  hill. 
  These 
  pieces 
  are 
  somewhat 
  fossilifer- 
  

   ous, 
  furnishing 
  the 
  following 
  list 
  :

  At 
  an 
  elevation 
  199 
  feet 
  above 
  the 
  railroad 
  is 
  an 
  ex- 
  

   posure 
  of 
  10 
  feet 
  of 
  rocks. 
  At 
  the 
  base 
  of 
  the 
  ledge 
  is 
  a 
  sand- 
  

   stone 
  which 
  splits 
  into 
  thin 
  layers 
  and 
  contains 
  an 
  occasional 
  

   fossil, 
  as 
  Camarotoechia 
  eximia 
  (Hall) 
  H. 
  & 
  C. 
  (?) 
  and 
  a 
  large 
  lamel- 
  

   libranch 
  shell. 
  Succeeding 
  the 
  thin 
  sandstones 
  are 
  quite 
  argilla- 
  

   ceous 
  shales 
  which, 
  are 
  also 
  fossiliferous 
  and, 
  above 
  the 
  shales, 
  

   sandstones 
  more 
  massive 
  than 
  those 
  at 
  the 
  bottom 
  of 
  the 
  ledge. 
  

   In 
  addition 
  to 
  those 
  mentioned 
  above, 
  the 
  ledge 
  furnished 
  the 
  

   following 
  species: 
  

  

  1 
  Tropidoleptus 
  carinatus 
  (Con.)
