  be 
  seen 
  that 
  in 
  the 
  vicinity 
  of 
  Livingstonville 
  to 
  the 
  east 
  and 
  

   west 
  of 
  Cat 
  skill 
  creek 
  there 
  are 
  remnants 
  of 
  the 
  Ithaca 
  fauna 
  

   above 
  these 
  lowest 
  red 
  rocks, 
  and 
  that 
  there 
  is 
  something 
  of 
  an 
  

   alteration 
  in 
  the 
  lithologic 
  appearance 
  characterizing 
  the 
  two 
  

   formations 
  where 
  typically 
  developed. 
  For 
  the 
  purpose 
  of 
  map- 
  

   ping, 
  however, 
  it 
  was 
  decided 
  to 
  consider 
  the 
  lowest 
  reds 
  as 
  form- 
  

   ing 
  the 
  base 
  of 
  the 
  Oneonta 
  formation 
  and 
  it 
  is 
  so 
  represented 
  on 
  

   the 
  accompanying 
  map. 
  

  

  Above 
  the 
  red 
  shales 
  of 
  D 
  2 
  the 
  rocks 
  are 
  so 
  well 
  covered 
  for 
  

   470 
  feet 
  that 
  no 
  red 
  rocks 
  were 
  seen 
  and 
  only 
  an 
  occasional 
  ledge 
  

   of 
  heavy 
  sandstone. 
  Near 
  the 
  upper 
  end 
  of 
  " 
  Cain 
  gulf 
  " 
  at 
  the 
  

   above 
  altitude 
  are 
  thin, 
  blue 
  sandstones, 
  (D 
  4 
  ), 
  having 
  a. 
  consider- 
  

   able 
  thickness 
  at 
  this 
  horizon, 
  and 
  in 
  the 
  field 
  not 
  far 
  from 
  this 
  

   level 
  a 
  sort 
  of 
  cornstone 
  was 
  found 
  in 
  which 
  there 
  were 
  a 
  few, 
  

   very 
  poorly 
  preserved 
  fossils. 
  The 
  species 
  are 
  Tropidoleptus 
  cari- 
  

   natus 
  (Con.) 
  Hall, 
  and 
  Spirifer 
  cf. 
  mucronatm 
  (Con.) 
  Bill., 
  the 
  lat- 
  

   ter 
  being 
  very 
  imperfectly 
  preserved, 
  and 
  perhaps 
  they 
  might 
  be 
  

   compared 
  with 
  S. 
  mesastrialis 
  Hall. 
  The 
  top 
  of 
  the 
  hill 
  is 
  some 
  

   265 
  feet 
  higher 
  but 
  the 
  rocks 
  are 
  poorly 
  exposed.

  . 
  One 
  mile 
  south 
  of 
  the 
  upper 
  part 
  of 
  section 
  LXXVID, 
  

   is 
  May's 
  hill 
  and 
  the 
  head 
  of 
  the 
  southwestern 
  fork 
  of 
  "Cain 
  gulf 
  " 
  

   brook. 
  Just 
  below 
  the 
  east 
  and 
  west 
  highway 
  is 
  a 
  fall 
  and 
  the 
  east- 
  

   ern 
  bank 
  opposite 
  shows 
  some 
  40 
  feet 
  of 
  grayish, 
  blue, 
  olive 
  and 
  red 
  

   argillaceous 
  shales 
  and 
  sandy 
  layers 
  to 
  thin 
  sandstones. 
  Not 
  

   much 
  below 
  the 
  crest 
  of 
  the 
  fall 
  in 
  a 
  somewhat 
  irregularly 
  grained 
  

   layer 
  having 
  red 
  argillaceous 
  shales 
  above 
  and 
  below 
  it 
  a 
  few 
  

   fossils 
  were 
  found. 
  Some 
  of 
  the 
  fairly 
  smooth 
  greenish 
  shales 
  

   contain 
  fragments 
  of 
  branching 
  plants. 
  The 
  fossils 
  are 
  as 
  fol- 
  

   lows 
  : 
  

  

  1 
  Brachiopod 
  sp. 
  (c) 
  

  

  2 
  Beyrichia 
  sp. 
  (r) 
  

  

  3 
  Orthonota 
  sp. 
  (rr) 
  

  

  The 
  above 
  fossiliferous 
  zone 
  is 
  75 
  feet 
  below 
  the 
  summit 
  of 
  the 
  

   divide 
  between 
  Livingstonville 
  and 
  Smithton 
  and 
  in 
  the 
  neighbor- 
  

   hood 
  of 
  800 
  feet 
  above 
  Livingstonville.
