  Potonie 
  mentions 
  Sigillaria 
  Brardi 
  as 
  a 
  typical 
  species 
  in 
  the 
  

   Ottweiler 
  Beds 
  and 
  in 
  the 
  Upper 
  Coal 
  Measures 
  and 
  Permian 
  rocks 
  

   generally. 
  1 
  This 
  species 
  is 
  recorded 
  by 
  Zeiller 
  from 
  the 
  Upper 
  

   Coal-Measure 
  and 
  Permian 
  beds 
  of 
  Brive, 
  2 
  as 
  well 
  as 
  from 
  the 
  Coal 
  

   Basin 
  of 
  Valenciennes, 
  3 
  also 
  from 
  the 
  Permian 
  rocks 
  of 
  Bohemia 
  4 
  and 
  

   the 
  Permian 
  of 
  Autun. 
  5 
  The 
  same 
  form 
  occurs 
  moreover 
  in 
  beds 
  

   referred 
  to 
  a 
  Permian 
  age 
  in 
  Pennsylvania. 
  6 
  Without 
  multiplying 
  

   references 
  to 
  this 
  species, 
  enough 
  has 
  been 
  said 
  to 
  show 
  that 
  it 
  points 
  

   to 
  a 
  high 
  horizon 
  in 
  the 
  Coal 
  Measures, 
  or 
  to 
  a 
  Permian 
  age 
  ; 
  as 
  

   Goppert 
  says 
  in 
  his 
  ' 
  Permian 
  Flora,' 
  the 
  species 
  is 
  not 
  uncommon 
  in 
  

   Permian 
  rocks. 
  

  

  There 
  is 
  also 
  some 
  evidence, 
  but 
  not 
  of 
  the 
  best, 
  of 
  another 
  

   species 
  of 
  Sigillaria, 
  S. 
  oculina, 
  occurring 
  in 
  the 
  Bunter 
  Sandstone 
  

   of 
  Germauy. 
  Blanckenhorn 
  7 
  figured 
  a 
  specimen 
  from 
  this 
  horizon 
  

   in 
  1886, 
  and 
  Weiss 
  8 
  subsequently 
  confirmed 
  his 
  determination. 
  

   The 
  preservation 
  is 
  by 
  no 
  means 
  good, 
  and 
  an 
  examination 
  of 
  

   a 
  cast 
  of 
  the 
  specimen 
  in 
  the 
  Bergakademie 
  Museum, 
  Berlin, 
  did 
  

   not 
  thoroughly 
  convince 
  me 
  as 
  to 
  the 
  Sigillarian 
  nature 
  of 
  the 
  

   fossil. 
  Blanckenhorn's 
  determination 
  has, 
  however, 
  been 
  accepted 
  

   by 
  Sterzel, 
  9 
  Potonie, 
  10 
  and 
  other 
  authors 
  in 
  addition 
  to 
  Weiss. 
  

  

  The 
  occurrence 
  of 
  Sigillaria 
  Brardi 
  at 
  Vereeniging 
  is 
  decidedlv 
  

   in 
  favour 
  of 
  the 
  view 
  already 
  expressed, 
  that 
  these 
  beds 
  should 
  be 
  

   referred 
  to 
  a 
  Permo-Carboniferous 
  age. 
  

  

  The 
  most 
  interesting 
  feature 
  in 
  connexion 
  with 
  the 
  occurrence 
  

   of 
  Sigillaria 
  in 
  South 
  Africa 
  in 
  association 
  with 
  Glossopteris 
  and 
  

   Gangarnopt 
  ris 
  is 
  the 
  coexistence 
  of 
  members 
  of 
  the 
  Glossopteris- 
  

   flora 
  and 
  a 
  typical 
  representative 
  of 
  the 
  Northern 
  Hemisphere 
  

   vegetation 
  of 
  Permo-Carboniferous 
  times. 
  In 
  1895 
  Zeiller 
  recorded 
  

   a 
  similar 
  association 
  of 
  Gangamopteris, 
  Lepidodendron, 
  and 
  Lepido- 
  

   phloios 
  in 
  the 
  coal-beds 
  of 
  Rio 
  Grande 
  do 
  Snl 
  in 
  Brazil.
