CARBONIFEROUS AND PERMC-CARBOMFEROUS ROCKS, N.S.W. 32 h 



ning of Mesozoic time. Professor J. W. Gregory, 1 has 

 commented on tlie distinctly Permian Age of the labyrintho- 

 dont Bothrlceps "which can hardly be Pre-Permian, and 

 Huxley indeed assigned it to the Trias." 



This occurs on the horizon of the Newcastle Coal- 

 measures of New South Wales, at Airly in the Western 

 Coal-field of New South Wales, and has been described by Dr. 

 A. Smith Woodward. 2 This is probably allied to Platyceps 

 Stephensl of the Wianamatta Shales (Upper Trias) of New 

 South Wales. 3 



Remains of a small labyrinthodont, imperfectly preserved 

 (the head, limbs and tail are missing) have been recorded 

 and roughly figured from the Latrobe Coal-measures* 

 (Greta) at Railton, Tasmania. 4 The Latrobe Coal-measures 

 are intercalated between Upper Marine and Lower Marine 

 Strata, and are the equivalents of the Greta Coal-measures 

 of New South Wales. A detailed examination of these 

 Latrobe labyrinthodont remains might throw important light 

 on the question as to whether the Greta Coal-measures 

 belong to Lower Permian or to Upper Carboniferous time. 



Before reviewing briefly "Permo-Carboniferous" Glacial 

 evidences from other parts of the world it may be mentioned 

 that so far no trace of Glacial deposits of late Palaeozoic 

 Age has been recorded from New Zealand. C.T.Trechmann* 

 has recorded the occurrence of Aphanaia, Martiniopsis (?), 

 Platyschisma etc., from rocks of the Maitai Series in New 

 Zealand, so that Permo-Carboniferous marine fossils are 

 present there, but hitherto no trace has been found, in New 

 Zealand, of a Glossopteris-Gangamopteris Flora.
