exhibits : 



1. Mr. W. N. Benson exhibited specimens of intrusive 

 tuffs from Tamworth and thin sections. 



2. Mr. W. R. Browne exhibited a Oycad, closely related 

 to Pterophyllum, from Newcastle. The fossil is very 

 similar in general character to P. distans of the Upper 

 Gondwanas of India. The specimen is of particular interest 

 as the occurrence of Oycads in the Permo-Carboniferous of 

 Australia has not been recorded since Alexander Berry's 

 remarks in his essay on the geology of the coast of N. S. 

 Wales, in speaking of the cliffs at the entrance to the 

 Hunter River, " I think I have been able to recognise the 

 leaf of the Zamia spiralis." (Barron Field, Geographical 

 Memoirs on N.S. Wales, 1825, p. 286). 



3. Judge Docker exhibited enlargements of photographs 

 taken in the Warrumbungle and Nandewar Ranges and of 

 geological interest, and other views. 



4. W. S. Dun exhibited a new species of fish from the 

 Brookvale brick pit.
