Belemnites were found in a calcareous conglomerate. In a creek a short distance to the 
north-east of Camp 81 (return journey), there occur largo quantities of ironstone 
nodules, in one of which I discovered a fine and very perfect crustacean, which, however, 
appears to have heenlost,* * * § as it was not noticed hy Mr. Etheridge, senr., when describing 
the Collection. The Mesozoic rocks here rest on a grey felsitic quartz-porphyry. 
“ At Camp 11 the Mesozoic beds consist of thin-beddod brown, olive, and 
whitish concretionary shales, passing downward into blue marly-shales, having a 
crystalline efilorescence on the surface (sulphate of soda ?) and decomposing rapidly. 
The olive-coloured limestone concretions form lines (in the shales) in the cliffs, like 
the flints in the chalk of England. These beds dip slightly northwards, and are faulted 
in several jilaces, and are jointed east and west. To the south the plains are occasionally 
covered with these boulder-hke concretions and glazed ironstone pebbles.f 
“ At Elizabeth Creek, between Camps 11 and 13, the cliffs consist of red and white 
conglomerates J passing downwards into sandy beds, which rest on blue shales and 
gypseous marls, with thin layers of gypsum and cone-in-cone limestone. Septaria also 
occur with veins of dolomite and centres of calc-spar. Irregular patches of red and 
yellow concretionary ironstone also occur, some pebbles having an external jet-black 
polish. With the exception of a fragment of an Orthooeras,% the only fossils I could find 
were Belemnites in a calcareous conglomerate at the base of the cliffs and obscured hy 
talus. 
“ At Camp 14, Mesozoic blue shales and concretionary limestones occupy the 
river bed, overlaid by a grey jointed calcareous sandstone. The rounded flattened 
concretions (not boulders) in these beds, as well as the beds themselves, contain a rich 
store of fossils, esjoecially Cephalopoda (Ammonites, Crioceras, &c.). These fossil 
beds are everywhere overlaid by siliceous pebbly conglomerates, coarse grits and 
sandstones, and ironstone and ferruginous grits.” || 
“ In a letter from the late Eev. W. B. Clarke to myself, dated 4th June, 1874, 
he says : “Prof. Etheridge (senr.) says of the Walsh River fossils, ‘there is no 
specimen of Orthoceras in the entire series,’ and Mr. Carruthers writes thus : ‘ There 
is not sufficient to warrant establishing a species, hut the fragments point to a form of 
Teeniopteris, nearly allied to Stranyerites ensis (Oldham and Morris in Indian Survey 
Memoirs), which Schimper calls Angiopteridium, We must have more materials, 
however, before we can be certain.’ ” 
The following is Mr. Etheridge’s description of the AValsh River fossils, quoted 
in a letter of the late Mr. K. T. Staiger, the then Curator of the Queensland Museum, 
Brisbane, dated 8th May, 1874. 
“ The Walsh River fossils consist of the following forms : — 
Cephalopoba. 
Ammonites, allied to A. clypeiformis. 
Ammonites, sp. (?) 
Crioceras (4), sp. 
Belemnites (2), sp. 
- All from nodules. 
* In a letter to me, dated 26th October, 1879, Mr. Taylor says ; “ In looking over the list of Queensland 
Exhibits, at Sydney, I find one by the Trustees of Brisb.ane Museum of a Crustacean unknown, from the 
Walsh, which must be my missing specimen.” (R.L.J.) The specimen exists in the Queensland Museum, 
and will be described, (B. E. Jiinr. ) 
t Mr. Skene, of Wrotham Park Station, assures’ me that Ammonites and Belemnites occur at 
Elizabeth Creek in situ, (B.L.J.) 
J Desert Sandstone, apparently. (B.L.J.) 
§ Probably the phragmaeone of a Belemnite. (B. E. junr.) 
II Desert Sandstone ? (B.L.J.)
