410 NOTES AND EXHIBITS. 



The limestone contains numerous foraminifera, and abundant 

 remains of small organisms, the precise nature of which has not 

 yet been determined. The specimen from which the sections 

 were cut was presented by Mr. C. W. Darley, M. Inst. C.E. The 

 rock is probably of Carboniferous age. (2) A specimen of fossil 

 algae C?), collected by Mr. C. Jenkins, from the Yass District, and 

 now in the Geological Collection at the University of Sydney. 



Mr. Mitchell, Narellan, exhibited some fossils from the Wiana- 

 matta Series, in the neighbourhood of Narellan, consisting of 

 insect remains and impressions of a plant apparently belonging to 

 the Tceniopteridce. Mr. Froggatt, of the Technological Museum, 

 had determined the insect remains to be referable to the Families 

 Blattid(e and BupreMidcE. Of the former there were impressions 

 of fragments of wings, and of the latter of an elytron. Mr. 

 Etheridge, Curator of the Australian Museum, to whom the 

 specimens had been submitted, confirmed Mr. Froggatt's opinion. 

 The plants consisted of fragments of leaves showing rows of 

 papillae along each side, or in some cases along one side, of the 

 midrib on the basal portion, which may be sori. The fossil 

 Orthoptera are from a railway cutting on the Great Southern line 

 at Glenlee; the Buprestid and plants from the Great Road about 

 a mile N.E. of Narellan. Mr. Mitchell also exhibited some oolitic 

 limestone found in a sample of lime from Marulan.
