  300 
  feet 
  higher. 
  Near 
  the 
  foot 
  of 
  this 
  hill 
  loose 
  flat 
  slabs 
  of 
  

   blue, 
  rather 
  fine 
  grained 
  sandstone 
  were 
  found 
  in 
  which 
  fossils 
  

   are 
  common. 
  It 
  is 
  not 
  probable 
  that 
  these 
  slabs 
  came 
  from 
  

   ledges 
  in 
  the 
  vicinity 
  of 
  Conesville 
  since 
  nothing 
  similar 
  to 
  them 
  

   was 
  found 
  in 
  place 
  in 
  that 
  region. 
  It 
  is, 
  however, 
  perhaps 
  

   worth 
  recording 
  that 
  two 
  loose 
  slabs 
  with 
  a 
  similar 
  fauna 
  were 
  

   noticed 
  in 
  the 
  gorge 
  of 
  the 
  Schoharie 
  river 
  below 
  Gilboa. 
  The 
  

   loose 
  blocks 
  back 
  of 
  Conesville 
  contained 
  the 
  following 
  species: 
  

  

  1 
  Spirifer 
  sp. 
  (c) 
  

  

  Specimens 
  badly 
  broken 
  and 
  imperfectly 
  preserved.

  Tropidoleptus 
  carinatus

  * 
  At 
  the 
  brow 
  of 
  the 
  hill 
  about 
  three 
  fourths 
  of 
  a. 
  mile 
  northeast 
  

   of 
  Conesville 
  is 
  a 
  ledge 
  of 
  gray 
  massive 
  sandstones 
  (Y 
  3 
  ) 
  45 
  feet 
  in 
  

   hight, 
  known 
  locally 
  as 
  " 
  The 
  Rocks," 
  and 
  fairly 
  well 
  shown 
  in 
  

   the 
  accompanying 
  plate. 
  The 
  base 
  of 
  the 
  ledge 
  is 
  225 
  feet 
  above 
  

   Conesville 
  and 
  approximately 
  620 
  feet 
  above 
  the 
  Schoharie 
  river 
  

   at 
  Gilboa. 
  Some 
  of 
  the 
  sandstone 
  is 
  thin 
  bedded, 
  while 
  other 
  layers 
  

   are 
  quite 
  massive 
  and 
  there 
  is 
  frequently 
  somewhat 
  irregular 
  

   structure. 
  Some 
  of 
  the 
  bluish 
  gray 
  sandstone 
  which 
  is 
  quite 
  

   coarse 
  grained 
  contains 
  a 
  few 
  poorly 
  preserved 
  fossils, 
  among 
  

   which 
  Spirifer 
  mesastrialis 
  Hall 
  is 
  the 
  most 
  common. 
  A 
  careful 
  

   search 
  furnished 
  the 
  following 
  species: 
  

  

  1 
  Spirifer 
  mesastrialis 
  Hall 
  (r) 
  

  

  Poorly 
  preserved. 
  

  

  2 
  Tropidoleptus 
  carinatus 
  (Con.) 
  Bill. 
  (r) 
  

  

  3 
  Pectinidae 
  (rr) 
  

  

  Too 
  imperfectly 
  preserved 
  for 
  generic 
  identification. 
  

  

  4 
  (?) 
  Actinopteria 
  sp. 
  (r) 
  

  

  Small 
  and 
  very 
  imperfectly 
  preserved 
  specimens. 
  

  

  5 
  (?) 
  Spathella 
  cf. 
  typica 
  Hall 
  (rr) 
  

  

  Larger 
  than 
  the 
  figures 
  of 
  this 
  species 
  but 
  in 
  outline 
  resem- 
  

   bles 
  it 
  more 
  closely' 
  than 
  any 
  of 
  the 
  other 
  figures.
