Viii PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [May 1 9 00. 



Prof. T. W. Edgewokth David, B.A., F.G.S., in exhibiting three 

 small glacially-striated boulders from the Hunter Biver District 

 (New South Wales), remarked that they were all obtained in situ. 

 One was discovered by Mr. W. G. Woolnough in the Upper Marine 

 beds of the Permo-Carboniferous rocks at Branxton, and the other 

 two are samples of a large number found, by Mr. E. C. Andrews 

 and Mr. 0. Trickett, of the New South Wales Geological Survey, 

 and the exhibitor, near Lochinvar in that colony. The horizon 

 from which these recently-discovered striated pebbles were collected 

 is probably not less than from 3500 to 4000 feet stratigraphically 

 below that in which occur the upper boulder-beds, wherein Mr. 

 II. D. Oldham had previously recorded the occurrence of a striated 

 pebble. Both glacial horizons are intimately associated with 

 marine Permo-Carboniferous beds, and they are separated one from 

 the other by the Greta Coal Measures (containing Glossojoteris 

 abundantly), as well as by about 4000 feet of marine Permo- 

 Carboniferous strata.
