110 REPORTS ON THE STATE OF SOIRNOE,~1917, 
intimately connected with the literature of the deposits as is Bacchus 
Marsh, and it is certainly more appropriate, since the Werribee River 
has cut the famous gorge through these glacial deposits, and thus 
enabled the series to be so well exposed. ; 
Though the term Permo-Carboniferous has priority and was made 
by such an eminent paleontologist as Mr. Robert Etheridge, jun., 
I prefer the term Carbo-Permian, for— 
(1). it would be uniform with the other Australian linked system 
names, such as Siluro-Devonian and Trias-Jura instituted by 
the same author; 
(2) it is a simpler term; and 
(3) it is I think equally expressive. 
I do not favour a single Australian name such as Hunterian for 
the whole of the deposits with glacial beds, having the same objection 
to that as Professor Skeats has. Neither Victoria nor South Australia 
has any known equivalents of the marine portion of the Hunter series. 
I may add that I think the Victorian glacials are lacustrine, as well 
as fluvio-glacial and land-ice deposits. 
Question 4.—I regard all the lower main glacial beds as contem- 
poraneous, and the differences in their upper portions as due to local 
glaciations of varying character, intensity, and extent. 
Question 5.—It appears desirable at present to accept the classi- 
fication suggested by Professor Skeats with the additions and modi- 
fications made by Professor David and Professor Woolnough, except- 
ing— 
(a) the Lower Maitai of New Zealand, and the Schizoneura Sand- 
stone of Victoria, about which I hold the same opinion as 
Professor Skeats ; 
(b) the separation anywhere by a definite line of the division between 
Permo-Carboniferous and Permian. 
In the light of our present knowledge it seems to me impossible 
to divide them. If the upper limit of Glossopteris marks the upper 
limit of the Permo-Carboniferous—and this seems doubtful—the 
deposits in New South Wales, Queensland, Western Australia, South — 
Africa, South America, Antarctica, the Falkland Islands, and India 
can scarcely be called Permian, and consequently the lines of division 
between the Permo-Carboniferous and Permian should be excised 
therefrom. The Beaufort and Ecca series are conformable according 
to Hatch and Corstorphine.? 
Question 6.—The Devonian and Carboniferous are conformable in 
Victoria. I offer no opinion regarding the other countries. 
Question 7.—The Carboniferous and Permo-Carboniferous appear 
to be conformable in parts of New South Wales, and certainly uncon- 
formable in other parts of that State, as proved by Professor David. 
There is no known contact of these in Victoria. The uppermost 
beds of the Grampians sandstones, however, when carefully examined 
may yield some useful information on the point. 
Question 8.—It seems to me that there is no definite evidence to 
separate the Permo-Carboniferous from the Permian in the Southern
