of fossils as showing the existence of a distinctly marked marine 
fauna in Australia, and then goes on to say that “the general 
aspect or facies of the Serpule, Brachiopoda, Lima, &e. is exactly 
that of those of the base of the Oolite and Lias beds, whilst some 
of the Monotis recall the Saliferous beds of Germany.” ‘‘ Perhaps,” 
he adds, “ one of the most interesting points in my examination of 
these fossils is my determination of Professor Bronn’s genus M/yo- 
phoria (nos. 23, 24, 29), so abundant in the Muschelkalk of Ger- 
many, strengthening my general reference of the whole to the base 
of the Mesozoic series, as well as suggesting, for the first time, the 
existence of the Muschelkalk m Australia, the only Kuropean forma- 
tion wanting in England.” His view of the general series was that 
they are “not younger than the base of the Oolite, nor older than 
the Trias.” 
The Rey. W. B. Clarke at the same time suggests (p. 52) the 
possibility of this group of fossils belonging to the Rhetic formation, 
and of the small fish-teeth found with them being identical with 
those found by myself in the Rheetic fissures near Frome. ‘The evi- 
dence that will be adduced will show that neither of the above con- 
clusions is correct, and that the whole series must be assigned to a 
higher position in the geological scale. 
The locality from which most of the specimens come is Wollum- 
billa, on the east side of the Fitzroy Downs, whilst a few are from 
the Fitzroy Downs, the Mitchell Downs on the Amba river, the 
downs on the Nive river, the Upper Maranoa west of Bendango, 
Mount Abundance, Blythesdale, and Bungeeworgorai, all in the 
Queensland colony. The Rey. W. B. Clarke has also forwarded me 
a photograph of a Cytherea from the Gregory River, a few miles 
north of Finnis’s Springs, on Stuart’s Route from Adelaide to Cham- 
ber’s Bay. 
As in the case of the remains already noticed from Western 
Australia, there appears to be little room for doubt that those now 
under consideration haye not been obtained from their parent bed 7m 
situ, but from the sides or beds of creeks, and from derived boulders 
scattered over the face of the Queensland Downs. 
As there are 38° of longitude between the district from which the 
Liassic and Oolitic specimens from Western Australia come and that 
of Wollumbilla, throughout which space as yet no Secondary beds 
appear to have been found in situ, we have evidence (which is also 
confirmed by the general character of the Australian continent) that 
there must have been an enormous denudation of the Secondary 
series over a considerable part of its surface between the deposition 
of the Paleozoic rocks and that of the Tertiary beds, the missing 
members of the Secondary series being as yet only made known to 
us by the comparatively meagre evidence afforded by the series of 
Mesozoic fossils now under consideration. 
In his ‘Recent Geological Discoveries in Australia’ (p. 52), the 
Rey. W. B. Clarke states that the Wollumbilla fossils occur in 
rounded, nodular, or concretionary boulders imbedded in a brittle 
marl in the creeks and on the downs, which are covered by grits
