  the 
  oblique 
  anastomosing 
  veins 
  may 
  be 
  readily 
  

   distinguished, 
  but 
  as 
  the 
  two 
  fragments 
  lie 
  in 
  different 
  planes 
  the 
  

   veins

  not 
  clearly 
  shown 
  in

  The 
  whole 
  specimen 
  

   is 
  by 
  no 
  means 
  clear 
  ; 
  it 
  is 
  possible 
  that 
  we 
  have 
  simply 
  an 
  accidental 
  

   association 
  of 
  what 
  appears 
  to 
  be 
  a 
  portion 
  of 
  a 
  NoeggeratMopsis- 
  

   leaf

  leaves

  Glossopteris.

  The 
  specimen 
  shown 
  in 
  PI. 
  XXII. 
  fig. 
  1 
  is 
  an 
  imperfect 
  impression 
  

   on 
  a 
  slab 
  of 
  iron-stained 
  sandstone 
  from 
  Vereeniging. 
  It 
  measures 
  

   10 
  cm. 
  in 
  length, 
  and 
  is 
  about 
  6 
  cm. 
  broad 
  ; 
  the 
  form 
  is 
  obovate 
  or 
  

   broadly 
  oval. 
  The 
  veins 
  spread 
  from 
  the 
  narrow 
  basal 
  portion 
  in 
  a 
  

   flabellate 
  manner, 
  and 
  along 
  the 
  median 
  line 
  they 
  are 
  almost 
  

   vertical 
  ; 
  the 
  details 
  are 
  not 
  at 
  all 
  clearly 
  seen 
  on 
  the 
  sandstone- 
  

   surface, 
  but 
  there 
  appear 
  to 
  be 
  indications 
  here 
  and 
  there 
  of 
  lateral 
  

   anastomoses. 
  The 
  form 
  and 
  general 
  appearance 
  of 
  the 
  leaf 
  remind 
  

   one 
  of 
  the 
  European 
  genus 
  Psygmophyllum 
  figured 
  by 
  Lindley 
  

   and 
  Hutton 
  1 
  from 
  England 
  as 
  Nceggeraihia 
  flabellata, 
  by 
  Schmal- 
  

   hausen 
  2 
  from 
  Russia, 
  etc. 
  A 
  comparison 
  may 
  also 
  be 
  made 
  with 
  

   Rhipidopsis 
  ginJcgoides, 
  Schmalh., 
  and 
  Palceovittaria 
  Kurtzi, 
  Feistm. 
  

   Among 
  Southern 
  Hemisphere 
  fossils, 
  some 
  of 
  the 
  Indian 
  leaves 
  

   figured 
  by 
  Feistmantel 
  as 
  Gangamopteris 
  cyclopteroides 
  3 
  agree 
  fairly 
  

   closely 
  with 
  the 
  present 
  specimen, 
  which 
  may 
  probably 
  be 
  referred 
  to 
  

   that 
  species. 
  The 
  same 
  author 
  has 
  also 
  figured 
  a 
  very 
  similar 
  leaf 
  

   from 
  near 
  Kimberley.

  The 
  smaller 
  leaf 
  (4-8 
  cm. 
  long) 
  represented 
  in 
  text-fig. 
  lc 
  (p. 
  324) 
  

   is 
  from 
  the 
  shales 
  of 
  Casey's 
  Township, 
  and 
  is 
  probably 
  an 
  example 
  

   of 
  the 
  same 
  species.
