   the

  clays

  the 
  brickyard 
  west 
  of 
  Barkwith 
  (now

   stated 
  by

  to 
  possess

   Further 
  north, 
  in 
  the 
  brickyard 
  | 
  mile 
  south 
  of 
  Holton-le-Moor 
  

   station, 
  are 
  dark 
  clays 
  with 
  : 
  — 
  

  

  Ammonites 
  decipiens, 
  Sow. 
  Ostrea 
  gibbosa, 
  Les. 
  

  

  Corbula

  At 
  the 
  brickyard 
  mentioned 
  above 
  as 
  occurring 
  \ 
  mile 
  west 
  of 
  

   Xorth 
  Kelsey 
  Station, 
  the 
  workmen 
  informed 
  me 
  that 
  when 
  the 
  pit 
  

   was 
  first 
  opened, 
  a 
  short 
  distance 
  to 
  the 
  east 
  of 
  where 
  they 
  are 
  now 
  

   at 
  work, 
  the 
  clays 
  were 
  so 
  full 
  of 
  oyster-shells 
  (like 
  0. 
  deltoidea 
  

   pointed 
  out 
  to 
  me) 
  that 
  they 
  proved 
  useless 
  for 
  brickmaking. 
  If 
  the 
  

   observation 
  of 
  these 
  men 
  can 
  be 
  regarded 
  as 
  trustworthy, 
  we 
  appear 
  

   to 
  have 
  at 
  this 
  point 
  clays 
  similar 
  to 
  those 
  of 
  West 
  Barkwith 
  and 
  

   Woodhall 
  Spa. 
  

  

  The 
  selenitiferous 
  clays 
  of 
  the 
  "YTrawby-Bridge 
  railway-cutting 
  

   mentioned 
  above 
  are 
  succeeded 
  by 
  dark 
  clays 
  with 
  brownish 
  iron- 
  

   stone 
  concretions 
  and 
  some 
  nodules 
  of 
  iron-pyrites. 
  They 
  may 
  he 
  

   seen 
  on 
  the 
  east 
  side 
  of 
  the 
  bridge, 
  but 
  their 
  junction 
  with 
  the 
  

   underlying 
  clays 
  cannot 
  be 
  seen, 
  because 
  it 
  is 
  concealed 
  by 
  debris. 
  

   These 
  clays 
  are 
  much 
  weathered 
  and 
  fossils 
  are 
  not 
  abundant 
  ; 
  

   nevertheless, 
  Ammonites 
  decipiens 
  is 
  fairly 
  common, 
  as 
  well 
  as 
  

   Thracia 
  depressa 
  and 
  Astarte 
  supracorallina. 
  Prof. 
  Blake 
  also 
  

   records 
  § 
  Ammonites 
  biplex, 
  Ceriihium 
  cerebrum, 
  Nvcula 
  Menkii, 
  

   and 
  Serpula 
  tetragona. 
  

  

  A 
  brickyard 
  at 
  the 
  south 
  end 
  of 
  the 
  village 
  of 
  Worlaby 
  is 
  opened 
  

   in 
  dark 
  blue 
  somewhat 
  sandy 
  clay, 
  with 
  brownish 
  ironstone 
  con- 
  

   cretions 
  and 
  some 
  iron-pyrites. 
  The 
  following 
  fossils 
  were 
  obtained 
  

   here 
  : 
  — 
  

  

  Ammonites 
  decipiens, 
  Sow. 
  Phaladomya 
  acuticosta, 
  Sow. 
  

  

  Cerithium 
  forticostatum, 
  Blake. 
  Ostrea 
  gibbosa, 
  Les. 
  

  

  Area, 
  sp. 
  Serpula 
  intestinalis, 
  Thill. 
  

  

  Prof. 
  Blake 
  mentions 
  [| 
  the 
  occurrence 
  in 
  this 
  pit 
  of 
  Lingula 
  

   oralis 
  and 
  Ammonites 
  biplex. 
  He 
  considers 
  the 
  clays 
  of 
  Worlaby 
  

   to 
  be 
  the 
  lowest 
  beds 
  of 
  the 
  Kimeridge 
  Clay 
  observed 
  in 
  Lincoln- 
  

   shire, 
  and 
  places 
  them 
  below 
  the 
  selenitiferous 
  clays 
  of 
  Wrawby- 
  

   B 
  ridge 
  cutting, 
  and 
  also 
  of 
  that 
  to 
  the 
  north-west 
  of 
  the 
  latter. 
  

   Lithologically, 
  however, 
  they 
  are 
  identical 
  in 
  character 
  with 
  the 
  

   clays 
  seen 
  in 
  the 
  eastern 
  half 
  of 
  the 
  Wrawby-Bridge 
  cutting. 
  The 
  

   most 
  common 
  fossil 
  present 
  in 
  both 
  is 
  Amm. 
  decipiens, 
  and 
  these 
  are 
  

   preserved 
  under 
  similar 
  conditions 
  ; 
  ironstone 
  concretions 
  and 
  iron- 
  

   pyrites, 
  not 
  noticed 
  elsewhere 
  in 
  the 
  Kimeridge 
  Clay 
  of 
  Lincoln-
