ON SOME MESOZOIC FOSSILS. 
By C. W. De VIS, M.A. 
Prominent iu an interesting collection of fossils made and 
liberally presented to the Museum by F. L. Berney, Esq., E. A.O.TL, 
of Wyangaria, I find more than one of so much promise that I am 
tempted to accept from them, as intermediary, whatever informa- 
tion they have to impart to the branch of science whose concern 
they are. I cannot persuade myself to pass on without venturing 
to pledge to Mr. Berney thanks other than " mine own " for his 
painstaking appreciation of the value to knowledge of relics of 
past life, an intelligent appreciation unhappily too exceptional. 
Would that more than the very few among the dwellers in our 
wilds at present known would help us onwards by utilizing to 
similar good purpose similar opportunities ! Wyangaria is a station 
in the neighbourhood of Richmond and Hughenden, approximately 
in lat. 121, long. 143, more precisely on O'Connell Creek, one of 
the headwaters of the northward flowing Flinders Eiver. 
There is presumptive evidence of the age of the fossils in 
question, in the fact of their occurrence on an area of that forma- 
tion which has been traced so far and wide over the surface of 
Northern Queensland, the Eolling Downs or Lower Cretaceous, 
conclusive testimony from the familiar fauna associated with them 
— e.g., Ichthyosaurus australis, Belemnites canhami, Aurella hughen- 
densis. Of the exact sfcratigraphical position of the beds con- 
taining them, I am uninformed. From the almost entire absence 
of fracture surfaces upon them, and the bold relief of their 
enclosed organisms, it seems allowable to suppose that they have 
been weathered out of beds which possibly have disappeared. The 
rock is a rather thin- bedded, highly calcareous marlite, disintegrated 
with brisk action by hydrochloric acid, and leaving, after solution of its 
lime, a copious residue of ferruginous alumina. Internally it is 
fine-grained, hard, very tough, and darkly coloured by iron oxide ; 
superficially it has, by partial loss of constituents, been rendered
