Area. 



By J. Dennant, F.G.S., and D. Clakk, B.C.E. 



[Eead 21st October, 1897.] 

 (With Plate VII.) 



The marine miocene in the neighhourhood of Jemmy's Point 

 was described by one of us in 1890/ and it was then advised 

 that furtlier explorations should be made in order to determine 

 more precisely the boundaries of the area occupied by such 

 strata. Some work in this direction has since been done by 

 Mr. W. Gregson and ouiselves, the results of which are now 

 given. 



Soon after the publication of the previous article, a junction 

 of the miocene and eocene strata was reported as visible at Swan 

 Reach on the Tambo, but we did not closely examine the section 

 till a few months ago on the occasion of a holiday trip to the 

 Gippsland Lakes. A road-cutting on the eastern bank of the 

 river, and about 100 yards south of the Punt Crossing at Swan 

 Reach, has exposed a tolerable thickness of the marine tertiaries. 

 A peculiar feature of the outcrop and that which distinguishes 

 it from junctions of similar strata noticed elsewhere, is that 

 certain characteristic fossils of the two horizons mentioned are 

 apparently mingled promiscuously together on the face, instead 

 of being strictly arranged in the order of their geological age. 

 Befoi'e, however, any explanation of this is attempted, it will be 

 necessary to give further details concerning the section. 



Though individual specimens are fairly numerous, the actual 

 number of miocene species represented is very small, the follow- 

 ing being the only ones we could find : — 



Pecten antiaustralis. Ostrea arenicola. 



Pecten meringte. Cidaris sp. (spines). 



Placunanomia ione. Balanus amaryllis.
