  sional 
  list 
  of 
  the 
  little 
  shells 
  from 
  the 
  lilera 
  clay 
  (No.

  after 
  a 
  prelimi- 
  

   nary 
  examination 
  of 
  them 
  by 
  Mr. 
  G» 
  Nevill 
  (late 
  of 
  the 
  Indian 
  Museum), 
  

   who 
  has 
  kindly 
  taken 
  them 
  in 
  hand 
  for 
  determination 
  and 
  description 
  :

   Besides 
  three 
  or 
  four 
  others 
  not 
  determined. 
  

  

  It 
  will 
  be 
  seen 
  that 
  the 
  collection, 
  though 
  small, 
  is 
  of 
  some 
  interest 
  

   A 
  deserted 
  extension 
  to 
  tlie 
  conchologist, 
  as 
  well 
  as 
  to 
  the 
  geologist, 
  

   of 
  the 
  gulf. 
  Tlie 
  general 
  facies 
  presents 
  a 
  mingling 
  of 
  brackish 
  

  

  water 
  with 
  marine 
  forms 
  ; 
  and, 
  in 
  connection 
  with 
  the 
  fact 
  that 
  the 
  

   locality 
  is 
  situated 
  65 
  miles 
  from 
  the 
  present 
  head 
  of 
  the 
  gulf, 
  bears 
  

   out 
  the 
  hypothesis 
  already 
  stated, 
  that 
  the 
  Ran 
  had 
  been 
  an 
  annexe 
  

   of 
  the 
  gulf 
  not 
  so 
  very 
  long 
  ago, 
  which, 
  as 
  the 
  salt 
  water 
  receded, 
  be- 
  

   came 
  silted 
  up. 
  

  

  A 
  belt 
  of 
  alluvium, 
  mostly 
  sub-aerial, 
  extends 
  along 
  the 
  northern 
  

  

  limit 
  of 
  the 
  Kathiawar 
  peninsula 
  : 
  its 
  outer

   Alluvium 
  near 
  the 
  Ran. 
  

  

  gin, 
  forming 
  the 
  southern 
  coast 
  line 
  of 
  the 
  Ran, 
  

  

  is 
  in 
  many 
  parts 
  loaded 
  with 
  sand 
  dunes 
  (raised 
  by 
  the 
  prevailing 
  wind 
  

  

  from 
  W.S.W.). 
  The 
  belt 
  varies 
  in 
  width 
  from 
  two 
  or 
  three 
  miles 
  at 
  

  

  Kuda, 
  to 
  about 
  sixteen 
  miles 
  in 
  the 
  Malia 
  district 
  ; 
  while, 
  in 
  the 
  east, 
  

  

  it 
  widens 
  to 
  six 
  or 
  seven 
  miles, 
  and, 
  sweeping 
  round 
  the 
  Jurassic 
  rock 
  

  

  area 
  of 
  Dhrangadra, 
  spreads 
  out 
  into 
  far-reaching 
  plains, 
  which 
  extend 
  

  

  into 
  the 
  Ahmedabad 
  country. 
  

  

  Along 
  the 
  inner 
  margin 
  of 
  this 
  alluvium, 
  there 
  are 
  sundry 
  accumula- 
  

  

  tions 
  which 
  I 
  regard 
  as 
  older 
  alluvium.
