NOTES AND EXHIBITS. 



A slab of white argillaceous sandstone was exhibited by Pro- 

 fessor David, showing at least five, possibly nine or ten, leaves of 

 the fossil fern Glossopieris attached to a thick stem, showing 

 prominent leaf-scars. The specimen was obtained from the 

 Western Coalfield, between Mudgee and Merriwa, and was pre- 

 sented to the Geological Department of the University of Sydney 

 by M. J. C. McTaggart, B.E., of the Water Conservation Branch, 

 Department of Mines. The discovery of this specimen is likely 

 to throw important light on the structure and affinities of what 

 was probably the predominant and most important member of the 

 flora of the productive Coal-Measures of New South Wales, 

 Queensland, Southern Africa, India and China. 



Mr. Froggatt showed specimens and drawings of galls and 

 coccids described in his paper. Also examples of a fungoid 

 growth upon the scales of an homopterous insect which attacks 

 the leaves of a Eucalypt, from Sutherland, near Sydney. 



Mr. Rainbow exhibited specimens of a remarkable spider, at 

 present undetermined, from Waterfall and from the Clarence 

 River. 



Mr. Maiden exhibited for Dr. Bancroft a photograph of a 

 flourishing pot plant of Marsilea Dmmmondii grown by him.
