  THE

  are 
  also 
  present 
  in 
  the 
  Glauconitic 
  Marls 
  near 
  the 
  base, 
  these 
  

   being 
  separated 
  from 
  the 
  Glanconitic 
  Sands 
  by 
  a 
  band 
  of 
  compact 
  

   yellow 
  sandstone.

  The 
  Glauconitic 
  Sands 
  are 
  well 
  exposed 
  at 
  low 
  tide, 
  and 
  are 
  

   of 
  the 
  usual 
  blue-green 
  colour. 
  Fossils 
  are 
  very 
  abundant.

   P.

  and 
  P. 
  Galliennii, 
  d'Orb., 
  are 
  by 
  no 
  

   means 
  uncommon, 
  and 
  a 
  special 
  feature 
  is 
  the 
  abundance 
  of 
  

   small 
  brachiopoda, 
  especially 
  Rhynchonella 
  near 
  Cuvieri, 
  Sow.,

  the

  No 
  continuous 
  sections 
  are 
  to 
  be 
  observed 
  north 
  of 
  the 
  exposure 
  

   just 
  described, 
  but 
  blocks 
  of 
  the 
  various 
  types 
  are 
  plentifully 
  

   scattered 
  along 
  the 
  shore. 
  The 
  Spongiarian 
  layer 
  is 
  particularly 
  

   prominent, 
  as 
  weathering 
  causes 
  the 
  sponge-fragments 
  to 
  stand 
  out 
  

   in 
  branching 
  masses 
  on 
  the 
  surface 
  of 
  the 
  rock. 
  Echinocorys 
  

   scutatus 
  is 
  also 
  abundant, 
  so 
  too 
  is 
  Camerospongia 
  fungiformis, 
  

   Goldf., 
  and 
  casts 
  of 
  lamellibranchiata. 
  

  

  The 
  character 
  of 
  the 
  Chloritic 
  Sands 
  was 
  well 
  illustrated 
  

   in 
  a 
  large 
  mass 
  which 
  had 
  slipped 
  down 
  the 
  hillside. 
  Instead 
  of 
  

   the 
  fossils 
  being 
  irregularly 
  scattered 
  throughout 
  the 
  rock, 
  clearly- 
  

   marked

  are
