Discussion. 
The Prustpent inquired whether the absence of reef-corals might 
not be indicative of the climate of South Australia having been much 
the same as at present in Tertiary times, as these forms required a 
temperature of about 68°. 
Prof. Ramsay expressed his satisfaction at the manner in which 
Mr. Selwyn’s work on the Australian Geological Survey had been 
appreciated by the author. 
Mr. Jenxins, who had been working on the foal mollusea of 
Australia, had arrived at the conclusion. that at the time of the de- 
posit of the beds mentioned by Dr. Duncan, the climate had been 
warmer than at present. The shells presented the same strange and 
abnormal features as the corals, in differmg from other older and 
well-known species merely in some minute detail. There was no 
point of contact between the Australian and European faunas to 
afford a criterion of relative age, though there were some points of 
similarity to be found in the Mediterranean area. 
Mr. Gwyn Jurrreys stated, as an instance of the singularities of 
the Australian fauna, that Rhynchonella psittacea, essentially an 
arctic species, had occurred in the Tertiaries of Spain, in our Glacial 
deposits and the Norwich Crag, and is now found living in 
Australia. 
Dr. Duncan shortly replied to the various speakers, and was dis- 
inclined to limit the occurrence of any forms of corals to particular 
temperatures. 
2. Nore on a New and UNDESCRIBED WEALDEN VERTEBRA. 
By J. W. Horxz, Esq., F.R.S., F.G.S. 
[Puate XXII. | 
Tus vertebra was found on the shore near Brooke, Isle of Wight, 
almost completely hidden in a large block of stone. Last autumn, 
when I obtained it, I showed the block to Mr. Fox, of Brighstone, 
whose knowledge of the Wealden strata in this neighbourhood is 
unrivalled; and he without hesitation referred it to a bed which 
occurs near the top of the high cliff between Brooke and Chilton.
