  Feistmantel 
  from 
  New 
  South 
  Wales 
  as 
  G. 
  Browniana 
  l 
  agree 
  very 
  

   closely 
  with 
  this 
  form 
  of 
  frond, 
  at 
  least 
  as 
  regards 
  the 
  venation. 
  

   The 
  specimen 
  represented 
  in 
  PL 
  XXI. 
  tig. 
  2 
  is 
  from 
  Casey's 
  Town- 
  

   ship 
  (Francis). 
  

  

  A 
  much 
  larger 
  portion 
  of 
  a 
  frond, 
  15 
  cm. 
  long 
  and 
  5 
  cm. 
  broad, 
  

   which 
  agrees 
  exactly 
  with 
  the 
  fragment 
  shown 
  in 
  PI. 
  XXL 
  fig. 
  2, 
  

   has 
  been 
  found 
  by 
  Mr. 
  Draper 
  in 
  the 
  coal-beds 
  of 
  Maggies 
  Mine. 
  

  

  PI. 
  XXI. 
  fig. 
  3. 
  (G. 
  Browniana 
  var. 
  indica.) 
  

  

  This 
  specimen 
  shows 
  the 
  venation 
  much 
  less 
  clearly 
  than 
  those 
  

   of 
  figs. 
  1 
  and 
  2, 
  PI. 
  XXI. 
  It 
  is 
  in 
  the 
  form 
  of 
  an 
  indistinct 
  

   impression 
  on 
  sandstone, 
  and 
  was 
  obtained 
  from 
  the 
  same 
  quarry 
  

   at 
  Vereeniging 
  as 
  that 
  which 
  afforded 
  the 
  specimens 
  of 
  Sigillaria 
  

   described 
  below. 
  The 
  length 
  of 
  the 
  leaf 
  is 
  14*5 
  cm., 
  and 
  the 
  

   broadest 
  part 
  measures 
  6 
  cm. 
  ; 
  the 
  midrib 
  is 
  well 
  marked 
  and 
  broad, 
  

   gradually 
  tapering 
  towards 
  the 
  frond 
  apex. 
  The 
  lateral 
  veins 
  are 
  

   very 
  numerous, 
  and 
  oblique 
  to 
  the 
  midrib, 
  agreeing 
  with 
  those 
  of 
  

   fig. 
  2, 
  PI. 
  XXI. 
  ; 
  the 
  leaf 
  should 
  most 
  probably 
  be 
  referred 
  to 
  the 
  

   same 
  species 
  — 
  G. 
  Browniana 
  var. 
  indica. 
  

  

  On 
  the 
  same 
  piece 
  of 
  sandstone, 
  which 
  is 
  practically 
  full 
  of 
  

   imperfect 
  leaf-impressions 
  and 
  forms 
  part 
  of 
  a 
  leaf-bed, 
  there 
  are 
  

   several 
  long 
  and 
  narrow 
  Glossopteris-le&ves 
  like 
  that 
  from 
  Casey's 
  

   Township 
  (Francis) 
  shown 
  in 
  PI. 
  XXI. 
  fig. 
  4a, 
  also 
  portions 
  of 
  Noeg- 
  

   gerathiopsis, 
  and 
  in 
  one 
  case 
  possibly 
  a 
  fragment 
  of 
  Gangamopteris 
  

   like 
  the 
  large 
  specimen 
  of 
  PI. 
  XXII. 
  fig. 
  1. 
  This 
  form 
  of 
  leaf 
  bears 
  

   a 
  close 
  resemblance 
  to 
  those 
  named 
  by 
  Feistmantel 
  ' 
  Glossopteris 
  

   damudica,' 
  2 
  which 
  it 
  is 
  difficult 
  to 
  distinguish 
  from 
  his 
  G. 
  communis 
  

   ( 
  = 
  G. 
  Browniana 
  var. 
  indica). 
  Compare 
  also 
  G. 
  ampla, 
  Dana.

  fig. 
  A 
  a. 
  (G. 
  Browniana 
  var. 
  angustifolia.) 
  

  

  Leaf 
  imperfect 
  ; 
  length 
  of 
  the 
  portion 
  preserved 
  17 
  cm., 
  and 
  

   breadth 
  about 
  2 
  cm. 
  The 
  venation 
  agrees 
  with 
  that 
  of 
  Brongniart's 
  

   type 
  of 
  G. 
  angustifolia, 
  and 
  indeed 
  with 
  G. 
  Browniana. 
  The 
  

   specimen 
  figured 
  by 
  Zeiller 
  as 
  G. 
  Browniana 
  in 
  pi. 
  xvi. 
  fig. 
  4 
  (op. 
  cit.) 
  

   bears 
  a 
  close 
  resemblance 
  to 
  this 
  specimen, 
  which 
  is 
  from 
  the 
  same 
  

   locality. 
  Several 
  smaller 
  and 
  less 
  perfect 
  specimens 
  of 
  this 
  form 
  of 
  

   leaf 
  have 
  been 
  found 
  in 
  the 
  sandstone 
  at 
  Vereeniging 
  in 
  the 
  beds 
  

   containing 
  Sigillaria, 
  and 
  in 
  one 
  or 
  two 
  of 
  these 
  impressions 
  the 
  

   broader 
  basal 
  part 
  of 
  the 
  short 
  petiole 
  is 
  clearly 
  shown. 
  In 
  cases 
  

   where 
  these 
  narrow 
  leaves 
  do 
  not 
  show 
  the 
  apical 
  portion, 
  it 
  is 
  

   possible 
  to 
  mistake 
  the 
  long 
  and 
  narrow 
  basal 
  portion 
  of 
  a 
  large 
  leaf 
  

   of 
  G. 
  Browniana 
  var. 
  indica 
  for 
  an 
  almost 
  complete 
  linear 
  leaf.
