of two species of fossils which have hitherto been held Creta¬ 
ceous, an additional example of the manner in which certain 
genera ascend in time to overlying formations (see pp. 1G, 31)* 
The latest discovery of the existence of Tertiary Marine fossils 
is on the S.E. Coast of New Guinea. On the voyage of the 
“ Chcvert,” the Hon. W. Macleay obtained a series of rocks and 
fossils, which 1 had the pleasure of seeing, and considered to be 
Tertiary. Since then they have been examined by Mr. C. S. 
"Wilkinson, whose experience of the Victorian Tertiaries is so 
well known. i I e has determined (“ Proe. Linn. Sue. N.S. W.f vol. 
i., pj>. 113-117) the following Lower Miocene shells, from Hairs 
iSound, most of which he recognizes as known in Victoria, and 
of which two have been described by Prof. McCoy (“ Prodrom. 
Pee. /”) : —

“Notes on a Collection of Geological Specimens collected by W. 
Macleay , Esq., F.L.S., Sfc., from the Coasts of New Guinea ’ Cape 
York, and neighbouring Islands: By C. S. Wilkinson , F.G.S ., Gov. 
Geologist .” 
The matrix of these fossils is described as exactly that of the 
Lower Miocene beds near Geelong and Cape Otway. At Jvatau, 
on the west side of the Bay of Papua, there are also fragments 
of shells in clay similar to those of Hall’s Sound and Yule 
Island. 
As described by Mr. Macleay, lltli Oct., 1875, Yule Island 
has a considerable inward clip from a horizontal face of cliff. 
The rock is calcareous, with corals, shells, echini, &c., bedded like 
the coral rag of Oxford. 13’Albertis mentions basalt in the 
valleys, and coralline cappings on the hills, which reach a height 
above the sea-level of from 600 to 700 feet. In Victoria there 
is a similar arrangement— “ Yellow and blue calcareous clays 
full of fossil shells, overlaid by thick beds of coralline limestone, 
consisting of an aggregate of comminuted fragments of shells 
and echinoderms.” 
Mr. "W ilkinson regards the ferruginous capping of the porphyry 
of Cape York, which is but 00 miles distant from the Papuan 
coast, as Tertiary, and that the New Guinea beds may be yet 
found in the Cape York Peninsula. Of course, future researches
