Isot very distant tlie same careful observer detected some of 
tlie same species as occur in Queensland in tlie middle Jurassic 
formation, described by Mr. Moore, c.r/., Asfarte icollumUllaensis, 
with other genera and species, that link in the South with the 
Korth Island (p. 105). These discoveries justify the inference 
that Triassic rocks arc probably present also ni New South Wales. 
^ When I first announced in 1860 the proof that Secondary fos- 
sils did exist in Australia, exhibited in Sydney, and forwarded 
to Sir Henry Barkly for Professor McCoy’s inspection I 
especially mentioned the occurrence of Cretaceous species. This 
was doubted, and the whole series classified as not higher'^ than 
the “ lower part of the great OoliteA But in 1S66, the Professor 
himself announced from another part of Queensland the occur- 
rence of two Inoceraynij and two Ammonites, from the Blinder’s 
Eiver district. He also announced an Icthgosaurus, a Plesio- 
saurus, a Belemnitella, from lower Cretaceous strata of the 
same district. 
Mr. Moore says, of the Wollumbilla fossils, that they all 
belong to the Upper Oolite may with safety be inferred, but the 
Cretaceous beds have a claim to be considered, and he established 
the existence of the genus Crioceras, which was first reported by me. 
In 1S72, j\Ir. Daintree, P.Gr.S., read his Xotes on Queensland, 
before the Geological Society, the marine fossils illustrating 
which were (as before stated), described by Mr. Etheridge, E.E.S., 
E.G.S., Paleontologist to the Geological Survey of Great Britain. 
The number of Oolitic species recorded is six, and of Cretaceous, 
twenty-five. 
The expedition of 1872, in the Cape York Peninsula, in which 
Mr. Yonnau Taylor, of the Yictorinn Survey, was Geologist, has 
added to the list of Secondary fossils in Queensland. These w^ere 
sent to me for inspection by the Minister for Public AYorks in 
that Colony, and at his request forwarded to the jAgent General 
in London. They have not yet been fully described. 
A still further amount of Cretaceous fossils forwarded by Mr. 
Hann, the leader of the Expedition of 1872, to Mr. Etheridge, 
and a large collection in my own cabinet, remain yet to be deter- 
mined. 
This is sufficient to show the extent of Mesozoic formations 
developed since 1860. 
Mr. Daintree reckons the areas of the Cretaceous and Oolitic 
formations in Queensland at 200,000 square miles ; the Carbon- 
aceous (Mesozoic) at 10,000, and the Palaeozoic Carboniferous 
at 14,000, wdiilst the Devonian and Upper Silurian occupy 
40,000. The two younger, therefore, are more ih-^wfive times as 
■extensive as the older. 
After the Herman Taylor collection had gone to England, I 
received three or four specimens from the Table Mountain,
