ADDENDUM. 



Since the tabulated list was set up I have received front 

 Mr. Waters a copy of his report upon the Polyzoa collected 

 during the voyage of the "Belgica" in the Antarctic Circle, 

 from which it appears that the following of our fossil species- 

 are living there : — Schizoporella rid ley i, McGr.; Smittia reticulata, 

 J. McG.; Smittia (Porella) marsupium, McG.; and Cellaria 

 dennanti, McG. This last species has not been found living 

 anywhere else, and it is included by Mr. Waters in the list of 

 " common " species.

Remarks on the Deposits. 

 By T. S. Hall. 



The marine tertiaries of Southern Australia cover a consider- 

 able area, and are rich in fossils, though at present pi^obably not 

 more than half of even the known species are described, these 

 being chiefly mollusca. No very full description of the beds as 

 they are displayed at the various localities as a vvhole has hither- 

 to been published, nor indeed is as yet possible. The most com- 

 plete is a series of three papers on their correlatioia, by the late 

 Professor R. Tate and Mr. J. Dennaut, in the Transactions of 

 the Royal Society of South Australia. A large series of papers 

 by various authors on the beds and their fossils will be found 

 chiefly in the same publication and in the Proceedings of this 

 Society. Tlie general sequence is fairly well agreed upon, but 

 there are differences of opinion in individual instances, evern 

 where the fauna of these is well known. A valuable census of 

 the fossils, by Messrs. J. Dennant and A. E. Kitson, has been 

 published by the Department of Mines of this State, but it may 

 as well be pointed out again that not half of the fauna is as yet 

 named, so that far-reaching conclusions based on a few simple 

 arithmetical calculations as to percentages and distribution are 

 not likely to be of any value at all. 



As to the age of the beds in European terms, differences of 

 opinion exist among those who have given attention to the sub- 

 ject. We are able to recognise three faunas. The most recent
