  In 
  the 
  

  

  fmall 
  gully 
  on 
  the

  side 
  of 
  the

  about 
  three-quarters 
  of 
  a 
  

  

  mile 
  north-east 
  of 
  Coopoor, 
  the 
  following 
  succession 
  of 
  beds 
  occurs 
  :

  Laterite 
  gravel.

  The 
  dip 
  of 
  these 
  beds 
  is 
  between 
  3° 
  and 
  5° 
  north. 
  Corresponding 
  

   beds 
  a 
  few 
  hundred 
  yards 
  to 
  the 
  east 
  show 
  a 
  dip 
  of 
  about 
  3° 
  north- 
  

   north-east. 
  No 
  fossils 
  but 
  a 
  few 
  small 
  stalk-like 
  fragments 
  of 
  plants 
  in 
  

   bad 
  preservation 
  were 
  found 
  by 
  me, 
  though 
  the 
  beds 
  were 
  very 
  carefully 
  

   searched, 
  but 
  Dr. 
  Hunter 
  and 
  Major 
  Applegath, 
  of 
  the 
  Madras 
  Staff 
  

   Corps, 
  both 
  state 
  that 
  they 
  have 
  found 
  plant 
  remains 
  in 
  the 
  shaley 
  beds 
  

   north 
  of 
  the 
  nullah 
  and 
  overlying 
  the 
  beds 
  of 
  the 
  above 
  section. 
  

   These 
  shaley 
  beds 
  are 
  much 
  obscured 
  by 
  the 
  lateritic 
  gravel 
  in 
  situ 
  

   and 
  as 
  debris. 
  

  

  In 
  a 
  lump 
  of 
  shaley 
  grey 
  clay 
  said 
  to 
  have 
  been 
  found 
  here, 
  

   Dr. 
  Hunter 
  showed 
  me 
  the 
  impression 
  of 
  a 
  fossil 
  bivalve 
  shell, 
  which, 
  

   if 
  my 
  memory 
  be 
  true, 
  is 
  identical 
  with 
  the 
  Q/pricardia 
  found 
  in 
  the 
  

   plant 
  shales 
  at 
  Amerumbode. 
  Dr. 
  Hunter 
  also 
  showed 
  me 
  a 
  drawing 
  

   of 
  a 
  plant 
  found 
  in 
  the 
  same 
  place, 
  and 
  strongly 
  resembling 
  in 
  its 
  

   outline 
  and 
  shape 
  a 
  pointed 
  Palcsozamia 
  frond, 
  but 
  the 
  venation 
  was 
  

   different, 
  and 
  probably 
  incorrectly 
  represented 
  as 
  concentric 
  to 
  the 
  

   external 
  edges 
  of 
  the 
  leaflets. 
  

  

  These 
  beds 
  unquestionably 
  extend 
  below 
  the 
  narrow 
  alluvial 
  valley 
  

  

  of 
  the 
  Cuum 
  river, 
  and 
  re-appear 
  at 
  the 
  village 
  

   Perumalpett 
  section. 
  

  

  of 
  Perumalpett 
  (Permalnaigpett 
  of 
  map), 
  about 
  

  

  three 
  miles 
  west-south-west 
  of 
  the 
  railway 
  station 
  at 
  Tinanoor.
