south, their general trend being E.-N.E.” The position of these 
exposures is opposite J 38. 
The only other catalogued fossiliferous limestone from the 
river bed is “ 2 limestone with fish palate, Camp Z 31, river bed 
Ord,” which obviously is not the specimen named by Mr. Etheridge. 
The specimen of Salterella hardmani in the Museum Collection 
is labelled HB 33, and was obtained from Mt. Panton. 
Hardman’s palaeontological observations in the field do not in 
any way lead to the belief that his locality south of Base Line or 
Base Line Camp refers to the Base Line laid down in 1883. 
Firstly, his list of specimens collected in 1883, in the Appendix of 
his Report for 1884, does not include a single fossil or fossiliferous 
specimen collected from or near Mt. Campbell, where the Base 
Line was situated 1 ; and, secondly, the fossils observed in the rocks 
near that locality show a purely Carboniferous facies, for they 
include Poteviocrinus, Athyris, and Lithodendron 2 in a good state of 
preservation. 
In the Report for 1884, numerous fossils are recorded from the 
Ord river district, including some purely Carboniferous genera, but 
there is some likelihood of Hardman’s field observations being 
at fault, for, unlike the fossils from the Western district, these 
latter were “ usually so worn by the excessive action of the weather 
in this tropical climate that identification as to species is almost 
impossible in many cases. ” 3 Of the genera mentioned, only one, 
Athyris, is more or less confined to the Carboniferous. 
LITHOLOGICAL EVIDENCE. 
In describing the Limestone Series (L) of the Ord District, 
Hardman says 4 : — 
“ 123. This portion of the limestone country rises in a succession 
of low and almost imperceptible terraces into high tablelands. 
One of these extends to the east of the Ord, near the ‘ Cattle 
Station,’ and another to the north and east of the Negri River, 
where it is capped by Mt. Panton.
