SUPPLEMENTARY NOTE. 
The fish which form the subject of Dr. Smith Woodward’s Monograph were 
collected by Mr. B. Dunstan, E.G.S., Acting Government Geologist of 
Queensland, from the brick pits of St. Peters, one of the Illawarra suburbs 
of Sydney. 
The clay which is quarried at these pits belongs to the Wianamatta 
shales, and constitutes the uppermost stage of the Triassic Hawkesbury Series. 
The Gosford fossil fish which were described by Dr. Woodward in his 
previous Memoir were collected from a horizon either at the top of the 
Narrabeen stage — which is separated from the Wianamatta by a thickness, of 
from nine hundred to one thousand feet of Hawkesbury Sandstones — or at 
the base of the Hawkesbury Sandstone itself. 
As Dr. Woodward has pointed out, the fish are found in two types of 
matrix, a greyish mudstone or shale, and an indurated shale or claystone. 
There are several bands of this harder rock in the quarries, constituting 
definite horizons, and separated by the mudstones. 
Mr. Dunstan’s collection was made at the following pits : — 
(a) Gentle’s Brick Pit — 
Myriolepis pectinata, Sm. Woodward. 
Elonichthys semilineatus, Sm. Woodward. 
Palaeoniscus antipodeus, Egerton.
