  Only 
  one 
  whorl; 
  too 
  imperfect 
  for 
  specific 
  identification. 
  

  

  Above 
  zone 
  D 
  2 
  are 
  much 
  finer 
  shales 
  (D 
  3 
  ) 
  which 
  contain 
  an 
  

   occasional 
  fossil 
  and 
  resemble 
  considerably 
  the 
  Sherburne 
  shales 
  

   of 
  Schoharie 
  co. 
  After 
  20 
  feet 
  of 
  these 
  shales, 
  however, 
  there 
  

   is 
  an 
  abundantly 
  fossiliferous 
  stratum 
  of 
  the 
  coarser 
  Ham- 
  

   ilton-like 
  shalee 
  (D 
  4 
  ) 
  but 
  a 
  little 
  more 
  than 
  a 
  foot 
  in 
  thickness. 
  

   Above 
  and 
  below 
  D 
  4 
  are 
  the 
  fine, 
  smooth 
  shales 
  containing 
  only 
  

   an 
  occasional 
  fossil. 
  The 
  fauna 
  of 
  D 
  4 
  is:
