 pJiyllia australiensis. 



CLASS FOEAMIN-IFERA. 



Mr. H. B. Brady, in Geological Magazine for July, 1876, 

 gives a list of 2^ species determined by him from material 

 obtained in sinking the Government Well between Burra and. 

 ]S'orth-A\^est Bend.

The major part of the species upon which the above sum- 

 mary is based consists of those which have been described from, 

 the actual beds, whilst the rest has been included on good 

 authority. Many more remain to be catalogued, as may be^ 

 gathered by reference to a census of the fauna of the Gastropod- 

 bed near Morgan submitted by me in the second volume of 

 our Transactions, p. liv., 1878. Since that time gatherings 

 have been repeatedly made, and the elaboration of the species 

 has received some attention. Many species have been identified 

 with those of the Mollusca described by AV^oods and McCoy, 

 and of Echinoderms by Duncan ; but a large proportion has^ 

 yet to be named. However, the Lamellibranchs are in course 

 of treatment by me after the plan adopted with regard to the 

 Palliobranchs of the Older Tertiary of Australia, and I trust 

 that before the lapse of many months the results will be before 

 you. AYhen the Gastropods shall have been similarly elabo- 

 rated, it will then be possible to correlate the various fos- 

 siliferous beds, and to promulgate more decided opinions as ta 

 the relationship of the fauna? i)ifer se and to those of other 

 Tertiary areas and to recent ones. 



In the lists of the characteristic species of the several sub- 

 divisions of the Murravian formation which follow I have 

 included only those of which diagnoses have been published^ 

 many of which are for the first time recorded as Murravian 

 fossils.
