  Heavy 
  concentric 
  markings 
  like 
  P.

  (Con.) 
  Hall; 
  

   but 
  there 
  is 
  no 
  constriction. 
  Something 
  like 
  the 
  shells 
  

   found 
  in 
  the 
  Ithaca 
  in 
  N. 
  E. 
  Pennsylvania. 
  

  

  Xot 
  far 
  west 
  of 
  West 
  Gilboa 
  loose 
  blocks 
  of 
  red 
  sandstone 
  

   occur 
  frequently 
  along 
  the 
  highway, 
  but 
  a 
  ledge 
  was 
  not 
  seen 
  in 
  

   place. 
  In 
  fact 
  there 
  are 
  but 
  comparatively 
  few 
  exposures 
  of 
  

   rocks 
  in 
  place 
  along 
  the 
  upper 
  course 
  of 
  the 
  Minekill. 
  Some 
  two 
  

   and 
  one 
  half 
  miles 
  above 
  West 
  Gilboa 
  loose 
  blocks 
  containing 
  

   fossils 
  were 
  seen 
  by 
  the 
  highway, 
  but 
  it 
  is 
  not 
  certain 
  that 
  they 
  

   came 
  from 
  that 
  immediate 
  vicinity. 
  In 
  these 
  blocks 
  the 
  follow- 
  

   ing 
  species 
  were 
  obtained:

  Spirifer 
  mesastrialis

  Homalonotus

  The 
  posterior 
  emargination, 
  as 
  in 
  Pennsylvania 
  specimens, 
  

   is 
  not 
  as 
  deep 
  as 
  on 
  typical 
  specimens 
  of 
  this 
  species.

  . 
  On 
  the 
  western 
  bank 
  of 
  the 
  Schoharie 
  nearly 
  two 
  

   miles 
  below 
  Gilboa 
  where 
  the 
  road 
  runs 
  very 
  near 
  the 
  river 
  are 
  

   massive 
  unfossiliferous 
  sandstones 
  which 
  are 
  fairly 
  coarse 
  grained 
  

   and 
  mostly 
  gray 
  in 
  color 
  with 
  but 
  a 
  faint 
  tint 
  of 
  green. 
  Perhaps 
  

   one 
  fourth 
  mile 
  belowthe 
  Gilboa 
  bridge 
  near 
  the 
  bank 
  of 
  the 
  river 
  

   is 
  a 
  small 
  quarry 
  E 
  2 
  which 
  has 
  been 
  worked 
  to 
  some 
  extent 
  for 
  

   building 
  stone. 
  The 
  rock 
  is 
  a 
  massive, 
  rather 
  coarse 
  grained, 
  

   greenish 
  gray 
  sandstone 
  which 
  runs 
  down 
  to 
  river 
  level, 
  some 
  

   20 
  feet 
  being 
  exposed. 
  No 
  fossils 
  were 
  found 
  in 
  the 
  bed 
  rock; 
  

   but 
  on 
  the 
  stone 
  wall 
  along 
  the 
  highway 
  at 
  this 
  locality 
  are 
  large 
  

   blocks 
  of 
  bluish 
  sandstone 
  containing 
  specimens 
  of 
  Tropidoleptus 
  

   carinatus 
  (Con.) 
  Hall; 
  Spirifer 
  sp.; 
  Glyptodesma 
  erectum 
  (Con.) 
  

   Hall 
  and 
  other 
  fossils. 
  Careful 
  search 
  was 
  made 
  for 
  this 
  zone 
  

   in 
  the 
  vicinity 
  of 
  Gilboa 
  but 
  without 
  success 
  and 
  it 
  is 
  probable 
  

   that 
  the 
  specimens 
  came 
  from 
  the 
  drift.
