  Description 
  of 
  the 
  Beds. 
  

  

  The 
  "Grey 
  Limestone" 
  of 
  Scarborough, 
  and 
  its 
  associated 
  and 
  alter- 
  

   nating 
  beds 
  of 
  sandstone 
  and 
  shale, 
  have 
  lately 
  attracted 
  the 
  atten- 
  

   tion 
  of 
  geologists 
  from 
  other 
  parts 
  of 
  England, 
  who, 
  aided 
  by 
  their 
  

   knowledge 
  of 
  the 
  Oolites 
  of 
  their 
  own 
  districts, 
  and 
  of 
  France 
  and 
  

   Germany, 
  have 
  done 
  much 
  to 
  establish 
  more 
  accurate 
  views 
  of 
  the 
  

   correlations 
  of 
  the 
  Yorkshire 
  beds. 
  

  

  I 
  do 
  not, 
  therefore, 
  hope 
  to 
  add 
  much 
  to 
  the 
  general 
  information 
  

   which 
  is 
  now 
  possessed 
  as 
  to 
  the 
  true 
  position 
  of 
  the 
  fossil 
  plant- 
  

   yielding 
  beds 
  at 
  Gristhorpe 
  Bay, 
  Cloughton 
  Wyke, 
  and 
  the 
  neigh- 
  

   bourhood 
  of 
  Whitby 
  ; 
  my 
  chief 
  intention 
  being 
  to 
  describe 
  and 
  figure 
  

   some 
  new 
  or 
  imperfectly 
  known 
  species, 
  and 
  to 
  point 
  out 
  certain 
  affi- 
  

   nities 
  and 
  differences 
  that 
  have 
  hitherto 
  escaped 
  detection. 
  

  

  Prof. 
  "Williamson, 
  in 
  a 
  paper 
  communicated 
  to 
  the 
  Geological 
  

   Society 
  in 
  1839f, 
  first 
  pointed 
  out 
  the 
  true 
  position 
  of 
  the 
  famous 
  

   plant-bed 
  at 
  Gristhorpe 
  Bay, 
  below 
  the 
  Grey 
  Limestone 
  ; 
  and, 
  in 
  

   1859, 
  his 
  views 
  were 
  confirmed 
  by 
  Dr. 
  Wright, 
  the 
  subject 
  being 
  

   considerably 
  amplified 
  in 
  a 
  paper 
  read 
  by 
  the 
  latter 
  author 
  before 
  

   the 
  Geological 
  Society 
  in 
  April 
  of 
  that 
  year 
  J. 
  I 
  have 
  only 
  to 
  add, 
  in 
  

   confirmation 
  of 
  these 
  opinions, 
  a 
  fact 
  which 
  is 
  not 
  made 
  sufficiently 
  

   prominent 
  in 
  Dr. 
  Wright's 
  paper, 
  that 
  from 
  the 
  first 
  appearance 
  of 
  

   the 
  " 
  Grey 
  Limestone 
  " 
  in 
  the 
  north 
  corner 
  of 
  Gristhorpe 
  Bay, 
  through
