At the “ Stone Hut,” on Eockwood Creek, is a bed of grey sandstone weathering 
buff, the lowest four inches of which is a sort of conglomerate of curious long oval 
pebbles of clay, which I think must be rolled casts of Zin^ula-like bivalves, together with 
fish-teeth, Echinus spines, Belemnites, Gasteropods, and Pelecypods. Among thespecimens 
which I brought home, my Colleague recognised fangs and tooth of Otodus, Belemnites, 
Amelia liugliendenensis, Eth., and sections of long spiral univalve shells. 
Half-a-mile east of Byrinnia Station are some quarries of blue-grey sandstone 
weathering buff, containing some shells. 
From Eockwood, on the Landsborough, grey sandstones and drab-coloured lime- 
stones are seen at intervals for sixteen miles, when, at the “ Jump Up” on the head of 
Jirking Creek, the Desert Sandstone unconformably overlies the Eolling Downs 
Formation. 
From the Junction of Eockwood Creek with the Landsborough, my Colleague 
recognised Inoceramus (a young form) among my Collection ; from the Landsborough, 
five and a-half miles north-north-west of Eockwood, Aucella hugliendenensis, Eth., 
and Pecten ; and, from near the head of Jirking Creek, Aucella Intghendenensis, Eth., 
and Pecten. In the same district numerous examples of Inoceramus were seen on the 
ground, but they were either too bulky, or too imperfect, to carry away. 
During a journey in the southern part of the Western Interior, in October and 
November, 1885, accompanied by Mr. J. B. Henderson, Hydraulic Engineer, I made the 
following notes : — 
At Minmi Old Station, on Bungil Creek, near Eoma, a soft dull-grey sandstone) 
with thin partings of blue shale, dips to S. at 2° to 3°. The sandstone contains 
numerous plant-impressions, some fragments of silicified wood, and fossil Pelecypoda, 
of which a list is given on a subsequent page. 
On the Maranoa Eiver, about half-a-mile north of the Eailway, are blue shales 
with bands of limestone nodules. The shales and limestone at the lowest point down 
the river dip up the river at about 15°. The remainder of the section dips, if 
anything, up the river, but is practically horizontal. From the limestone nodules I 
obtained numerous fossils, among which my Colleague recognised the Pelecypoda, of 
which a list is also given on a subsequent page.* 
On To To Creek, a tributary of the Warrego, in Lat. 26° S., is a section 
of green sandstone with calcareous and ferruginous parts, and grey shales, and 
cone-in-cone limestone in very thin bands. Ironstone nodules in the shale contain 
doubtful leaf-impressions and shells, and the sandstone contains Belemnites. The 
Eolling Downs rocks are seen at intervals between To To Creek and Ellangowan. 
* In a collection from the Lake Eyre Basin, submitted by Prof. K. Tate to the undersigned, an 
exactly similar matrix and mode of preservation of tho fossils exists. (R, E. Junr.)
