CARBONIFEROUS ROCKS OF THE SOUTHERN HEMISPHERE. 107 
stephensi occurs at Pokolbin in the Lower foraminiferal band, and is 
also found at the Irwin River in W.A-, where Foord regarded the beds 
as Carboniferous). 
5. Vredenburg correlates the Middle Gondwana with the New Red 
Sandstone. This would make our Glossopteris flora much younger 
than generally believed. 
6. They are often so conformable as to be indefinable as separate 
systems at their junction. We 
Notes on Prof. Skeats’ Table of Correlation. 
In the Indian column should not the ‘ Panchet’ series read ‘ Rani- 
ganj’? The Panchet series equals New Red Sandstone. Between the 
Damuda and the Talchir comes the sub-stage of ihe Karharbari beds. 
In the Victorian column the upper plant-bearing sandstones of 
Bacchus Marsh are probably Triassic. 
’ In the Queensland column I would place the Star series low down 
in the Carboniferous, since Lépidodendron is so abundant, and there 
also occurs Receptaculites australis (at Mt. Wyatt), which in Victoria 
and N.S. Wales is found in the Middle Devonian. 
The Permo-Carboniferous System in Tasmania. 
By W. H. Twenverrers, F.G.S., Government Geologist of Tasmania, 
The stratigraphical development of this system in Tasmania is, in 
descending order, as follows: 
5. Coal measures at Mt. Cygnet and on Bruny Island, which are 
perhaps the uppermost beds of the system. 
4. Upper marine series of mudstones, sandstones, and limestones. 
3. Coal measures and Tasmanite beds in the Mersey basin. Coal 
measures at Preolenna. — 
2. Lower marine series of mudstones, limestones, and mudstone 
conglomerates, frequently carrying glacial erratics. — 
1. Basal beds of glacial conglomerate and till. 
The beds nowhere rest on Carboniferous strata, but on Devonian 
granite or on Silurian or older rocks. 
The coal measures of the system are characterised by a Gangamo- 
pteris and Glossopteris flora. 
The only correlation with other countries suggesting itself as practi- 
cable and reasonable (and that a partial one) is with the Gondwana and 
Salt Range deposits in India, the Karroo in South Africa, the Orleans 
conglomerate in Brazil, and the San Luis conglomerate in Argentina. 
The glacial conglomerates and tills at the base of the system in Tas- 
mania are with great probability homotaxial with the basal conglomerates 
in New South Wales, the Bacchus Marsh conglomerates in Victoria, 
the Dwyka conglomerate in South Africa, the Indian Talchir conglome- 
rate, and the Boulder bed of the Salt Range in the Punjab. In all 
these continents the overlying beds contain the remains of a common 
flora (Gangamopteris and Glossopteris) and pass upwards into strata 
with plants of a Triasso-Rhatic type.

Tasmania, such as Conularia, Martinopsis darwini, Aviculopecten
