A correlation with Sues sections was attempted by the same 
author, op. cit. II., p. lii., and at p. ivi. the term Eocene was 
applied to the Lower Aldinga Seri ies, and that of Miocene to the 
Upper Series. 
4. Kangaroo Island.—The small outlier of Eocene limestone 
near Kingscote, first indicated by Peron, has been described by 
Tate, op. ae Wipro, S62. 
5. River Murray Plain.—tThe literature relating to the geology 
of this extensive area, as well as detailed descriptions of the sec- 
tions, age, and eoereleon, has been dealt with by Tate, op. cit. 
VIL, pp. 24-41, 1885. 
6. Mount Gambier District.—Tenison Woods’ ‘“ Geological Ob- 
servations,” London, 1867, embodies the chief literature’ relating 
to the geology of this area. 
Mr. Edward V. Clark, in a paper read this year before this 
Society submits proof of the subter-connection of the limestones 
of the Mount Gambier area with the more arenaceous beds of the 
Murravian area, and indicates the occurrence of deeper-seated 
sands, the fossils of which seem to be part of the fauna character- 
ising the inferior beds of the Aldinga section. 
II. MiocENE AND ITs RELATION TO EOCENE. 
1. River Murray Cliffs. > Murravian 
Series were detached from the underlying Eocene calciferous 
sandstones on paleontological data, but re-examinations of the 
section in the cliffs at Nor-West Bend leave no doubt of a 
genuine erosive surface between the two sets of beds. 
2. Adelaide.—Burr* was the first to describe the lithological 
features of the beds on which the city of Adelaide stands, and 
considered them to belong to the Tertiary period, without assign- 
ing any definite age. Sturt recognised, however, that these beds
