For sometime past the fossil fern Tniopteris, to which is allied 
Oleandridium, has been known to occur in the beds both above 
and below the Hawkesbury Sandstones, but as far as I know, 
there has been no record made of its occurrence in these particular 
beds. 
Professor David has noted the presence of Macrotceniopteris in 
the Narrabeen Shales, and Mr. R. Etheridge, Junr., the Govern- 
ment Paleontologist, has informed me he found traces of Tent- 
opteris and Macroteniopteris in some of the many lenticular 
patches of shale occurring in the sandstones around Sydney. 
Oleandridium, however, until now has not been found anywhere 
in our sedimentary rocks, and judging from the number of impres- 
sions which may be seen on single blocks of stone, the deposits 
which I have discovered, when opened out, would prove to be 
immensly rich in these plant remains. All the fossils obtained 
by me were from exposed places, and probably, by further excavat- 
ing much better preserved specimens would be found. 
The locality in which the deposits of these plant remains occur 
is about a mile and a quarter north of Manly, and is known as 
Freshwater, being the second point on the coast line north of 
Manly Ocean Beach. (See accompanying sketch plan.) 
The outcrop of the fossiliferous bed, which is shale and shaly- 
sandstone of about twenty-five feet in thickness, is very conspicu- 
ous on the south side of the point, where a good natural section 
isexposed to view. The sketch section on the accompanying plan 
will show its relation to the beds above and below it.
