Cretaceous Fossils in Australia. AY 
Art. VII.—On the Decomposition of Pyrites. By Mr. 
SHIRESS, of Ballarat. : 
[Read by the President, 10th December, 1866.] 
This paper treated of a new method of decomposing 
pyzites by bringing the ore in contact with the fuel. 
[Subsequently Mr. Shiress was requested to furnish the 
Council with some data by which a conclusion could be 
arrived at as to the correctness of the theory ; but this Mr. 
Shiress has not thought proper to do.—ED.] 
Art. VIII.—On Three New Victorian Birds. By PROFESSOR 
M ‘Coy. 
Professor M‘Coy exhibited a specimen of the Herodias 
grezetta, shot in Gipps Land. This has been only doubtfully 
added by Gould to the list of Australian birds, from inspec- 
tion of a photograph of a specimen killed in Queensland. 
The Victorian specimen exhibited was not only new to the 
colony, but the first of the kind that had been actually 
identified with the species from actual comparison. The 
second new Victorian bird exhibited was a new species of 
Bristle-bird, Sphenura Broadbentt (M‘Coy), found by Mr. 
Broadbent near Portland. The third was a new species of 
Pardalotus, recently described under the name P. Xanthopyge 
(M‘Coy), first noticed by Mr. Leadbeater, taxidermist at the 
Museum, but previously confounded with the P. pune- 
tatus. 
The characters of all these forms were dwelt on in detail, 
and the specimens exhibited have been in the National 
_ Museum for two years. 
Art. IX.—On the Discovery of Enaliosauria and other Cre- 
taceous Fossils in Australia. By Prorrssor M‘Coy. 
This paper was to illustrate a small but most valuable 
series of fossil specimens, sent by Mr. James Sutherland to 
Professor M‘Coy, from the head of the Flinders, for the 
National Museum, in continuation of the series formerly 
described before the Society, presented by Messrs. Sutherland 
and Carson, of Collins-street, and which enabled Professor
