  SIGILLARTA 
  AND 
  GLOSSOPTERIS 
  IN 
  SOUTH 
  AFRICA. 
  [Aug. 
  1 
  897, 
  

  

  particularly 
  clear, 
  but 
  the 
  speaker 
  had 
  found 
  Glossopteris 
  in 
  the 
  

   Marine 
  Series, 
  thus 
  placing 
  the 
  matter 
  beyond 
  all 
  doubt. 
  

   . 
  Feistmantel 
  has 
  described 
  the 
  Palaeozoic 
  plants 
  ; 
  but 
  there 
  is 
  a 
  

   difficulty, 
  as 
  stated 
  by 
  Mr. 
  Seward, 
  in 
  distinguishing 
  forms 
  ; 
  and 
  in 
  

   1894 
  Mr. 
  R. 
  Etheridge, 
  Jun., 
  pointed 
  out 
  that 
  the 
  whole 
  question 
  

   of 
  generic 
  name, 
  specific 
  characters, 
  etc. 
  of 
  Glossopteris 
  had 
  become 
  

   almost 
  hopelessly 
  involved. 
  Gangamopteris 
  and 
  Glossopteris 
  are 
  

   associated 
  at 
  Lochinvar 
  and 
  Newcastle 
  (N.S.W.). 
  

  

  Mr. 
  Mark, 
  in 
  the 
  absence 
  of 
  the 
  Authors, 
  pointed 
  out 
  that 
  

   Mr. 
  Seward's 
  paper, 
  which 
  had 
  been 
  read 
  in 
  very 
  brief 
  abstract, 
  

   was 
  mainly 
  palaaobotanical, 
  and 
  that 
  the 
  evidence 
  brought 
  forward 
  

   by 
  Dr. 
  Blanford, 
  Dr. 
  Waagen, 
  and 
  others 
  as 
  to 
  the 
  age 
  of 
  the 
  beds 
  

   was 
  relied 
  upon 
  by 
  Mr. 
  Seward.
