1. On the Term Permo-Carboniferous and on the Correlation of thal 
System. By W. S. Dun and Professor T. W. Epaswortu Davin, 
C.M.G. 
The term Permo-Carboniferous was originally applied to certain formations 
in Queensland which on stratigraphical evidence were at the time considered 
to belong to one and the same general system. At the time it was considered 
that a series of strata at Gympie, which contained an assemblage of fossils 
of distinct Permian affinities, were stratigraphically below another set of 
strata known as the Star Beds. The latter contain among other fossils 
Phillipsia, Lepidodendron australe, and Aneimites, all typical Carboniferous 
fossils in Australia, and the first mostly of Devonian age. Accordingly these 
formations were grouped together under the term Permo-Carboniferous, and 
the name has subsequently been widely used. It has now been proved that, so 
far as Queensland is concerned, the name has been given in error. The 
Gympie Beds are stratigraphically above the Star Beds, not below as was 
originally supposed. Nowhere in Australia or Tasmania has a single trilobite 
or Lepidodendron ever been found in our Carboniferous rocks proper. In the 
absence of a zoning of these Carboniferous rocks it is impossible to say what 
exactly are its equivalents in other parts of the world. If it is wholly Lower 
Carboniferous, as some suppose, there may be some justification for the retention 
of the term Permo-Carboniferous, but if its fauna and flora ascend to Upper 
Carboniferous, then it is suggested that there is much to be said in favour of 
using the term Permian instead. In Russia Schizodus occurs in fiumbers 
beneath the whole not only of the Glossopteris beds, but of the Gangamopteris
