also to the Victorian Cainozoics.* He further remarks that. 
“The Miocene clay beds of New Guinea, judging from the 
Specimens collected by Mr. Macleay, are exactly similar 
in lithological character to the Lower Miocene beds near 
Geelong, and on the Cape Otway coast in Victoria.’’ 
Wilkinson accepted McCoy’s conclusions as to the Miocene 
age of the Victorian beds, when he compared them with 
the clays of Hall’s Sound. Since that time, however, some 
authors have relegated the Victorian beds above named to 
the lower series, the Hocene. Latterly the writer, having 
obtained what he regards as conclusive evidence of the 
Sequence and relative ages of the Victorian beds, finds it 
supports the original idea of McCoy’s, that the Geelong 
and Torquay series are comparable with the Miocene beds. 
of the northern hemisphere. It will, therefore, be of great 
interest if we can obtain further evidence from Papua as. 
to the relationship of the blue clays to the Lepidocyclina. 
limestone herein described. 
Wilkinson also referred to an oolitic limestone occurring 
at Bramble Bay,* which he thought to be an upper bed of 
the Miocene formation. Itis here suggested that this and 
the brecciated rock composed of corals, shells and echinoids, 
from Yule Island, may have some age affinity with the 
present brecciated limestone. Sofar as we can judge from 
the paleontological evidence, both the Voluta clays and 
the Lepidocyclina limestone occur on or about the same 
horizon; the latter by its characteristic species denoting 
an Upper Aquitanian stage, whilst the Cape Otway series. 
probably comprises that and the succeeding Burdigalian 
stages, as seen in the shell marls of Bird Rock and the 
polyzoal rock of Spring Creek and Batesford’ respectively. 
* Wilkinson rightly refers the two species named as common to the 
Otway series, now called Janjukian, and not, as would be gathered from 
Mr. Etheridge’s note (Pal. Queensland and New Guinea, 1892, p. 697), 
denoting the fauna of Schnapper Point, Mornington and Muddy Creek.
