In New South Wales the same two divisions have been recognised ; 
and although hut little detailed mapping has been done, much general 
information relating to the occurrence and nature of the beds has been 
obtained, as already mentioned, by Mr. Pittman and his Officers. The former 
gives a summary of the subject in his recently- issued work — “ The Mineral 
Resources of New South "Wales.” ^ I do not propose to enter upon a geological 
description of our Cretaceous deposits ; Imt for further information the reader 
is referred to the works catalogued in the accompanying Bililiography, for 
which I am indebted to Mr. W. S. Dun, Paleontologist to the Geological 
Survey. 
Tlie time is not far distant when we shall be in a position to break up 
our Continental Cretaceous System into a number of well-defined life zones, 
marking equally w'ell-defined geological horizons — i.e., a series of beds in 
which certain species, or some one sjiecies in particular predominates to the 
exclusion of otliers equally indicative of tlic system as a whole, although not 
cliaracteristic to the same extent of tlie beds in question. My studies in 
Queensland and South Australian Cretaceous Palaeontology confirm this. I 
am a strong advocate of adopting Euro^iean or other foreign nomenclature 
for our groat geological divisions of strata only in the broadest sense, i.e., 
from the homotaxial standpoint, regarding them merely as apparently 
occupying the same relative position in tlie geological series, and not as 
precisely synchronous. "Within such divisions I similarly advocate the 
employment of local terms for minor divisions of strata. 
In certain of our Systems this has already been carried out to some 
extent. Por instance, the "Wianamatta, Ilawkesbury and Clarence Series, of 
Clarke and "Wilkinson, in that group of strata believed to be homotaxial 
Avith the Trias of other parts of the Avorld ; the subdivisions now adopted in 
distinguishing our Coal Measures and associated marine strata, through the 
researches of Keene, Mackenzie, AVilkinson, and David, and grouped as a 
Avhole under the term Permo-Carboniferous, suggested by myself ; the names 
employed by McCoy and Selwyn, in Victoria, and Jack, in Queensland, to 
subdivide the strata believed to represent the Devonian of other countries, 
such as the Buchan and Bindi Limestones, &c., or the Burdekin and Panning 
Limestones in the latter of the tAVo States, to say nothing of the potentialities 
of the great Cambrian area of South and Central South Australia foreshadoAved 
by the laliours of Tate, BroAvn, and IIoAVchin. Similarly, I am of opinion 
that equally useful subdiAusions will be possible in the Cretaceous.
