Memoir by Mr. Wilkinson (as quoted by Duncan) the reference 
to these rocks is not very clear, though some portions at least 
seem to have been recognised as younger than Miocene, and are 
called “‘more recent Tertiary sandstone.” So far as the section 
given affords a clue, the dune limestone, with its characteristic 
variation of dip, is apparently indicated. We shall notice this 
section at greater length presently in the special description of 
the Aire River rocks. 
Cape Otway is 39 miles from Forrest, the nearest railway 
station, and only 14 miles from Krambruk (Apollo Bay), the 
terminus of a coach-line ; but, though in reality not more than a 
day’s journey from Melbourne, the nature of the country renders 
travelling difficult, and it is seldom visited, except by a few ad- 
venturous tourists. At the Aire River, five miles west of Cape 
Otway, our guide assured us that probably no one had been on 
the beach for three years prior to our visit. From Krambruk 
travelling is either on foot or on horseback, and if a stay at the 
Cape is intended it is necessary to take materials for camping, 
the proverbial hospitality of Western Victoria being there con- 
spicuous by its absence. At the Aire River we were most hos- 
pitably entertained by Mr. Robinson, the genial proprietor of the 
Aire Cattle Station. 
Cape Otway. 
Although called by the above name, the section is really about 
one and a half miles west of the Cape and close to Point Flinders. 
The fossils occur in great abundance on the surface of mound- 
like masses of slate-colored stiff clay which extend from sea-level 
up to a height of about 40 feet. ‘The chief shells are species of 
Turritella and Pleurotoma, the latter being especially character- 
istic of the bed. As the list appended shows, numerous other 
species occur, but relatively to those named they are individually 
scarce, many species in our collections being represented by one 
or two examples only. It is useless to dig for fossils, as just 
below the surface the clay appears quite barren, though of course 
the shells are there, but undistinguishable until the clay is 
washed away from them. The fossiliferous patch is very limited 
in extent, but as the tops of isolated mounds crop out from under 
the sand for a few chains to the west, it is probable that the clay 
underlies for a considerable distance. 
To the east mesozoic rocks rise on the cliffs, and the fossilifer- 
ous clay disappears. Resting upon the tertiaries, or, when they 
are wanting, directly upon the mesozoic strata, is a layer of dune 
limestone of variable thickness, and again upon this the ordinary 
sand dunes of the coast. 
At Point Flinders itself small streams of clear sparkling water 
fall over the face of the rock. Their origin is interesting, as
