﻿CLASSIFICATION,

  LXXV 
  M. 
  A 
  section 
  was 
  roughly 
  measured 
  from 
  the 
  Schoharie 
  

   river 
  bridge 
  below 
  North 
  Blenheim 
  along 
  the 
  highway 
  and 
  brook 
  

   up 
  the 
  steep 
  hill 
  on 
  the 
  eastern 
  side 
  of 
  the 
  river 
  through 
  Mackey's 
  

   Corners 
  to 
  the 
  top 
  of 
  Leonard 
  hill 
  in 
  the 
  eastern 
  part 
  of 
  the 
  town- 
  

   ship. 
  The 
  hill 
  slope 
  is 
  well 
  covered 
  by 
  drift 
  so 
  that 
  the 
  section 
  

   is 
  not 
  as 
  satisfactory 
  as 
  might 
  be 
  desired. 
  For 
  440 
  feet 
  up 
  the 
  

   hill 
  the 
  rocks 
  are 
  all 
  concealed 
  along 
  the 
  highway^ 
  when 
  an 
  ex- 
  

   posure 
  of 
  bluish 
  shales 
  (M 
  2 
  ) 
  occurs 
  in 
  which 
  are 
  a 
  few 
  poorly 
  pre- 
  

   served 
  fossils. 
  

  

  1 
  Liorhynchus 
  multicosta 
  Hall 
  (?) 
  (c) 
  

  

  The 
  specimens 
  are 
  all 
  quite 
  small 
  and 
  resemble 
  the 
  " 
  young 
  

   individual," 
  fig. 
  26, 
  pi. 
  5G, 
  Paleontology, 
  v. 
  4, 
  more 
  closely 
  

   than 
  any 
  other.

  Coleolus 
  tenuicinctum 
  Hall'(?)

  Just 
  the 
  point 
  of 
  apparently 
  a 
  specimen 
  of 
  the 
  above 
  

   species. 
  

  

  So 
  few 
  fossils 
  were 
  found 
  in 
  these 
  shales 
  that 
  they 
  assist 
  very 
  

   little 
  in 
  determining 
  their 
  age 
  but 
  judging 
  from 
  the 
  sections 
  on 
  

   • 
  the 
  western 
  side 
  of 
  the 
  river 
  at 
  North 
  Blenheim 
  it 
  seems 
  probable 
  

   that 
  they 
  are 
  not 
  older 
  than 
  the 
  Sherburne 
  formation. 
  40 
  feet 
  

   higher 
  are 
  coarse 
  grained, 
  thin 
  gray 
  sandstones 
  (M 
  3 
  ) 
  which 
  con- 
  

   tain 
  more 
  fossils 
  both 
  in 
  number 
  of 
  specimens 
  and 
  species, 
  as 
  will 
  

   be 
  seen 
  by 
  following 
  list: 
  

  

  1 
  Spirifer 
  mucronatus 
  (Con.) 
  Bill. 
  (c) 
  

  

  2 
  Chonetes 
  setigera 
  Hall 
  (c) 
  

  

  3 
  Tropidoleptus 
  carinatus 
  (Con.) 
  Hall 
  (r) 
  

  

  4 
  Leda 
  diversa 
  Hall 
  (rr) 
  

  

  5 
  Orthonota 
  undulaia 
  Con. 
  (rr) 
  

  

  6 
  Schizodus 
  appressus 
  (Con.) 
  Hall 
  (rr) 
  

  

  7 
  OrUculoidea 
  sp. 
  (rr) 
  

  

  The 
  species 
  in 
  this 
  list 
  are 
  Hamilton 
  and 
  on 
  account 
  of 
  their 
  

   stratigraphic 
  position 
  they 
  are 
  not 
  diagnostic. 
  The 
  outcrop 
  is 
  

   probably 
  in 
  the 
  Ithaca 
  formation 
  and 
  is 
  something 
  like 
  800 
  feet 
  

   below 
  the 
  fossiliferous 
  sandstones 
  of 
  LXXV 
  N 
  2 
  , 
  on 
  the 
  hill 
  to 
  the 
  

   southeast. 
  Then 
  for 
  about 
  390 
  feet 
  the 
  rocks 
  are 
  mostly 
  covered 
  

   till 
  in 
  the 
  upper 
  part 
  of 
  the 
  small 
  brook 
  thick 
  bedded, 
  coarse,
