  Some 
  Gaj 
  beds 
  are 
  exposed 
  in 
  the 
  steeply 
  scarped 
  coast 
  line, 
  about 
  a 
  

   mile 
  and 
  a 
  half 
  below 
  the 
  mouth 
  of 
  the 
  stream 
  just 
  mentioned. 
  A 
  yellow 
  

   and 
  marly 
  c 
  rag 
  ' 
  bed 
  is 
  the 
  most 
  conspicuous 
  ; 
  from 
  it 
  an 
  inferior 
  build- 
  

   ing 
  stone 
  has 
  been 
  extracted 
  for 
  the 
  Thakor's 
  summer-house, 
  lately 
  built 
  

   on 
  the 
  high 
  ground 
  above 
  the 
  scarp. 
  The 
  rock 
  is 
  for 
  the 
  most 
  part 
  

   saline, 
  and 
  weathers 
  rapidly 
  on 
  the 
  surface 
  into 
  a 
  fine 
  powder. 
  From 
  this 
  

   rock 
  the 
  following 
  fossils 
  were 
  obtained 
  : 
  — 
  

  

  PeLecypoda. 
  

   Venus, 
  sp. 
  ? 
  (cast). 
  

   PecteUy 
  comp. 
  corneus, 
  Sow. 
  

   P. 
  sp.? 
  

  

  Ostrea, 
  sp. 
  ? 
  (very 
  small). 
  

  

  Bryozoa. 
  

   Lunulites 
  , 
  sp. 
  ? 
  (abundant). 
  

  

  ECHINODERMATA. 
  

  

  Cidaris, 
  spines. 
  

   In 
  one 
  place 
  a 
  close 
  clay-shale, 
  pale 
  greenish 
  in 
  colour, 
  is 
  seen 
  resting 
  

   upon 
  the 
  marly 
  limestone 
  ; 
  no 
  fossils 
  were 
  detected 
  in 
  the 
  shale. 
  

  

  In 
  the 
  tide 
  way 
  along 
  the 
  coast 
  at 
  Gogha, 
  and 
  for 
  some 
  distance 
  

  

  towards 
  Kura, 
  there 
  are 
  very 
  fine 
  soft 
  silty 
  flags 
  

   Coast 
  flags 
  at 
  Gogha. 
  

  

  and 
  sandstones, 
  that 
  harden 
  considerably 
  on 
  expo- 
  

   sure 
  to 
  the 
  air, 
  when 
  they 
  form 
  a 
  fair 
  paving, 
  or 
  flooring 
  stone, 
  and 
  are 
  

   largely 
  used 
  for 
  that 
  purpose 
  in 
  Bhavnagar. 
  At 
  Gogha 
  itself, 
  the 
  sand- 
  

   stones 
  are 
  coarser 
  and 
  rusty 
  brown 
  in 
  colour 
  ; 
  with 
  conglomeratic 
  bands 
  

   and 
  layers 
  among 
  them, 
  enclosing 
  clay 
  pebbles 
  and 
  ferruginous 
  galls. 
  

   These 
  rocks 
  have 
  all 
  the 
  appearance 
  of 
  identity 
  with 
  the 
  beds 
  of 
  Piram. 
  

   This 
  little 
  island, 
  which 
  " 
  is 
  simply 
  a 
  reef 
  of 
  rock 
  covered 
  in 
  part 
  by 
  

  

  blown 
  sand/' 
  l 
  is 
  situated 
  about 
  four 
  miles 
  off 
  the 
  

   Piram 
  Island.

  a 
  paper 
  read 
  before 
  the 
  Bombay 
  

  

  Geographical 
  Society 
  in 
  1838, 
  mentions 
  that 
  it 
  is 
  1,800 
  yards 
  long, 
  and 
  

  

  300 
  to 
  500 
  yards 
  wide, 
  lying 
  north-north-west 
  and 
  south-south-east;
