Obviously, the as yet unknown history of the Palaeozoic Eoraminiferal 
Fauna of N. S. Wales in pre- Permo-Carboniferous time offers an inviting field 
for research, as also does the relation of the Permo-Carboniferous Foraminifera 
to those of the Great Cretaceous Basin of Australia. The general absence of 
any Marine Trias- Jura rocks in Eastern and Central Australia makes it 
improbable that the missing evidence will be supplied from those regions. 
West Australia, however, possesses a Marine Jurassic Fauna, and it is 
not unlikely that the deeper marine strata beneath the Jurassic basins may 
be even of Triassic Age. 
It is, therefore, chiefly to West Australia that we may look for an 
ultimate solution of the problem as to bow our Cretaceous Foraminiferal 
Fauna became evolved out of the Permo-Carboniferous ancestors described in 
this Monograph. 
Appended is a section showing the stratigraphical relations of the 
Foraminiferal Horizons of Wollong and Pokolbin.
