INTRODUCTION. 
In 1864 the coast-line in the neighbourhood of Cape Otway was 
surveyed and reported upon by Messrs. Wilkinson and Daintree, 
of the Geological Survey of Victoria. Collections of fossils were 
made by them, but with the exception of the corals, have been 
apparently laid aside and forgotten. Their report is out of 
print, and for the preservation of portions of its contents, as well 
as for the drawings of coast sections accompanying it, we are in- 
debted to Professor M. Duncan, who made copious extracts from 
it when describing the corals in the Geological Society’s Journal.* 
A second survey of the coast was made by Mr. Krause in 1873,+ 
but as he was principally engaged in searching for outcrops of 
coal, the conclusions of his predecessors concerning the geological 
details of the coast-line seem to have been accepted. An 
elaborate plan of the coast was issued by the Mining Department 
as the result of this survey, giving topographical as well as 
geological information. Notwithstanding some errors in the 
Aire River portion of the district, we found the sheets useful as 
a topographical guide, but, as we shall show in the sequel, grave 
blunders appear in the mapping of the tertiary outcrops from the 
Aire River to Castle Cove. Wedo not allude to the mistake 
almost universal with the earlier geologists of Victoria in re- 
garding undoubted Eocene strata as Miocene. This may be ex- 
pected, and the necessary correction is now almost unconsciously 
supplied, but in the case before us an area some miles in extent 
is colored Miocene (Eocene) on the map where certainly the pre- 
vailing, if not the only outcropping, rocks are the ordinary Post- 
Pliocene, or recent dune limestones, so common on our coasts. 
As is well known, they are eolian rocks. In the original
