  GROUP,

  view 
  as 
  well 
  the 
  age 
  of 
  the 
  group 
  in 
  question 
  and 
  the 
  evidence 
  of 
  order* 
  

   ly 
  deposition 
  which 
  seems 
  to 
  have 
  prevailed 
  from 
  the 
  termination, 
  at 
  

   least 
  of 
  the 
  Secondary 
  period 
  down 
  to 
  the 
  present 
  time, 
  I 
  think 
  we 
  are 
  

   justified 
  in 
  regarding 
  the 
  boundary 
  of 
  the 
  Axial 
  group 
  as 
  a 
  faulted 
  one 
  

   (at 
  least 
  on 
  its 
  Eastern 
  side), 
  and 
  the 
  elevation 
  of 
  this 
  portion 
  of 
  the 
  

   range 
  towards 
  the 
  frontier 
  along 
  a 
  line 
  of 
  fault 
  as 
  a 
  distinct 
  process, 
  

   supplemental, 
  perhaps, 
  but 
  differing 
  both 
  in 
  kind 
  and 
  degree 
  from 
  that 
  

   to 
  which 
  the 
  general 
  formation 
  of 
  both 
  the 
  Arakan 
  and 
  Pegu 
  ranges 
  is 
  

   due, 
  as 
  previously 
  described. 
  

  

  The 
  alternative 
  explanation 
  of 
  the 
  juxta-position 
  of 
  the 
  Axial 
  and 
  

   Nummulitics 
  through 
  either 
  denudation 
  of 
  the 
  older 
  beds 
  prior 
  to 
  the 
  

   deposition 
  of 
  the 
  newer, 
  or 
  the 
  overlap 
  of 
  the 
  latter 
  over 
  the 
  former, 
  

   though 
  not 
  impossible, 
  is 
  too 
  unsupported 
  by 
  evidence, 
  and, 
  as 
  I 
  think, 
  

   too 
  opposed 
  to 
  the 
  general 
  tenor 
  and 
  succession 
  of 
  geological 
  conditions^ 
  

   as 
  they 
  seem 
  to 
  have 
  obtained 
  over 
  this 
  area 
  during 
  the 
  period 
  in 
  ques- 
  

   tion, 
  to 
  require 
  to 
  be 
  discussed 
  at 
  length 
  ; 
  and 
  the 
  subject 
  will 
  best 
  be 
  

   considered 
  when 
  we 
  are 
  in 
  possession 
  of 
  some 
  knowledge 
  of 
  the 
  relations 
  

   of 
  the 
  Axial 
  and 
  newer 
  groups, 
  on 
  either 
  side 
  of 
  the 
  Arakan 
  range, 
  at 
  a 
  

   higher 
  parallel 
  of 
  latitude 
  than 
  that 
  we 
  are 
  at 
  present 
  restricted 
  by. 
  

  

  The 
  best 
  characterised 
  portion 
  of 
  this 
  group 
  is 
  what 
  I 
  have 
  designa- 
  

   ted 
  the 
  upper 
  Axials 
  in 
  my 
  sketch 
  of 
  this 
  group 
  in 
  the 
  Records 
  of 
  the 
  

   Geological 
  Survey 
  (vol. 
  iv, 
  for 
  1871, 
  page 
  36). 
  At 
  the 
  base 
  of 
  this 
  upper 
  

   division 
  occur 
  the 
  only 
  two 
  beds 
  "wherein 
  I 
  have 
  detected 
  fossils, 
  though 
  

   I 
  am 
  sanguine 
  of 
  future 
  researches 
  in 
  this 
  group 
  revealing 
  a 
  richer 
  

   fauna, 
  when 
  a 
  wider 
  area 
  of 
  these 
  beds 
  comes 
  under 
  observation. 
  This 
  

   upper 
  group 
  extends 
  from 
  the 
  frontier 
  down 
  to 
  the 
  point 
  where 
  the 
  Axials 
  

   disappear 
  on 
  the 
  bank 
  of 
  the 
  Thanni 
  stream. 
  These 
  beds 
  are 
  first 
  seen 
  

   along 
  the 
  West 
  bank 
  of 
  the 
  Moo 
  stream, 
  and 
  are 
  well 
  displayed 
  in 
  a 
  

   feeder 
  of 
  the 
  Moo, 
  near 
  Kondeing-zu 
  or 
  (Kondeing-keng) 
  , 
  and 
  thence 
  on 
  

   to 
  Khyoung-tha. 
  The 
  beds 
  near 
  Kondeing-zu 
  are 
  in 
  places 
  vertical, 
  or 
  with 
  

   a 
  high 
  dip 
  to 
  West-by-north 
  ; 
  between 
  this 
  and 
  Khyoungtha 
  the 
  high 
  dip
