Twenty-five miles below Marathon Station the road began to be strewn with 
“cone-in-cone” limestone, evidently derived from beds w beneath, and from one 
to four inches in thickness. About a mile further I saw fine-grained yellow sandstones 
and grey shales dij)ping at 7° to the S.E. 
Three miles above Richmond Downs I observed the following section: — 
ft. in. 
Shales, say 4 0 
Soft grey and yellow sandstone 2 0 
Limestone 0 6 
The bottom of the limestone had a cone-in-cone structure, and the top was full 
of shells, which my Colleague named Carsoni, McCoy, J. Sutlierlandi, 'M.cQoy, 
and Inocemmus, a third species. Daintree’s observation, already quoted, that the 
cone-in-cone limestone contains no fossils, and has the appearance of a chemical 
2 )reeipitate rather than that of a mechanical deposit, will be remembered. I saw an 
Inoceramus quite a foot in length, but was unable to detach it from the matrix. 
Between Richmond Dowms Station and the Ffinders, yellow sandstones having a 
slight dip to the south-east were observed. In similar sandstone below the stockyard 
I found an Inoceramus. Near the Richmond Downs Post Office I saw a fragment of an 
immense Griooeras lying on the roadside. 
Thirteen and a-half miles below Richmond Downs Station a gully falling into the 
left bank of the Plinders exposed a section of crumbling grey and bluish shales with 
limestone and grey calcareous sandstone. Prom these 1 obtained specimens of 
Inoceramus Carsoni, McCoy. 
Twenty-one and a-half miles below Richmond Downs Station, a gully on the left 
bank of the river showed a scarp of about twenty feet of brown shales, overlaid by grey 
sandstones, with an apparent dip (though undulating) up the river. Prom the shales I 
obtained Inoceramus Sutherland i, McCoy. 
Eight miles further the bed and banks of the Plinders expose a series of blue- 
grey shales and thin-beddod and flaggy soft fine-grained blue -grey sandstone, 
dipping about 3° to the E. In the sandstone I saw only a fragment of a largo flat 
bivalve. 
At the crossing of Neelia Creek I found Aucella Imghendenensis, Eth., and 
Inoceramus in a bed of limestone. Brown sandstone and cone-iu-cone limestone are 
seen at the crossing. 
Por sixteen miles beyond Neelia Creek the road is covered with loose blocks of 
grey sandstone and conc-in-eone limestone. Belemnites are occasionally seen on the 
surface. On some ridges sixteen miles from Neelia Creek, I saw sandstone and cone-in- 
cone limestone dipping slightly to the east. 
Between Neelia and Julia Creeks, grey and brown sandstone and cone-in-cone 
limestone are frequently seen. At Julia Creek I found the Gasteropod named Natica 
JacTcii, Eth. flh, and a fragment of a Cephalopod. 
Sections of brown flaggy sandstone and cone-in-cone limestone are exposed by 
Box Creek. 
One mile west of the Williams River is an outcrop of semi-vitreous sandstone 
containing Belemnites and nodules of limestone resembling “curling stones” in size and 
shape. 
Eight miles beyond the Williams are blocks of a very hard brecciated siliceo- 
calcareous stratified rock, from which I obtained Inoceramus. Portions of the rock -were 
almost entirely made up of the disintegrated shelly fibres of this genus. I also observed 
in one piece the impression of a Belemnite.
