108 REPORTS ON THE STATE OF SCIENOE.—1917. 
(Deltopecten) limeformis, &c., are repeated in the Salt Range Boulder 
bed, which lies there also at the base of the system. Moreover the 
same fossils, as well as Productus brachytherus, Spirifera vespertilio, 
Lurydesma globosum, EH. cordatum, &c., contained in the Speckled 
Sandstone and Lower Limestones which succeed the Boulder bed in 
the Salt Range, are also common forms in the Tasmanian Lower Marine 
beds. 
The Indian Gondwana beds of the Talchir division which succeed the 
Talchir Boulder bed, and the succeeding Karharbari beds, contain a 
flora identical with that of the Mersey Coal measures in Tasmania; 
and the same may be said of the Ecca series which succeeds the Dwyka 
basal conglomerate of the Karroo system in South Africa. 
In Tasmania the Lower Marine strata are overlain by the Mersey 
Coal measures with the Glossopteris and Gangamopteris flora, and 
these are succeeded by the Upper Marine beds containing organic 
remains for the most part similar to those of the Lower Marine, but 
less abundant, and some familiar species of the lower division appear 
to be absent. 
The thickness of the maximum development of the beds belonging 
to this system is estimated at nearly 3,000 feet. The strata are hori- 
zontal or gently inclined. They have not been deformed by crustal 
folding, but have been greatly depressed or raised by block-faulting. 
The whole assemblage of the Permo-Carboniferous and Trias-Jura 
sediments in Tasmania may in a broad sense be conceived as belonging 
to a Gondwana Land system if we extend the meaning of the latter 
term so as to include both continental formations and the marine de- 
posits fringing the shores of the ancient continent. It would seem 
desirable to devise some name which would express this relationship 
and at the same time put an end to the controversies which rage round 
the use of the terms Permian and Permo-Carboniferous, besides avoid- 
ing the unnatural and confused employment of European nomenclature. 
Provisionally, however, the term Permo-Carboniferous is in common 
use, gives expression to the facts, and ought not to be exchanged for 
any other which implies homotaxial correspondence or contemporaneity 
with European systems. ; 
There seems to be no stratigraphical reason why the Permo-Carboni- 
ferous of this island should not share any common name which may be 
decided on for the same system as a whole as developed in Australia. 
Permo-Carboniferous Rocks in New Zealand. 
By Professor P. Marswauu, M.A., D.Sc., The University, Dunedin, 
S. Island, New Zealand. 
The fossils originally recorded by McKay from the Wairoa Gorge, 
Nelson, viz. Productus brachytherus, Spirifera bisulcata, S. glabra, 
Cyathocrinus and Cyathophyllum, have recently been unpacked at the 
Dominion Museum, Wellington, and are now available for study. 
They are quite different from any fossils that have been found else- 
where in New Zealand. Additional specimens have lately been found 
in the same place by Mr. C. T. Trechmann. These fossils quite 
possibly indicate a Permo-Carboniferous age, but accurate identifi-
