divided into three parts, and provisional estimates of each arc given. The 
classification is the following : — 
Upper Devonian — 
Iguana Creek beds : Sedimentary forma- I 
tions with plant remains j — 5,750 feet. 
Snowy Bluff beds : Contemporaneous fel- | 
sites and basalts J 
Middle Devonian — 
Upper Buchan beds : Marine fossiliferous 
limestones = 100 to 500 „ 
Lower Buchan beds : Calcareous tufas, 
felsito tufas, breccias, &c =750 to 1,000 „ 
Lower Devonian (?) — 
Snowy lliver porphyries : Eelsite ash, 
agglomerates, massive fclsitos, &c = 2,000 ,,

The Bacchus Marsh beds are spoken of thus : — £c Blanking the extre- 
mity of the Silurian ranges of the Lcrderderg, and extending from westward 
of the Werribee gorge to the lower portion of Goodman’s Creek, arc thick- 
bedded sandstones, shales, and mudstone conglomerates, classed on the 
geological maps as Upper Palaeozoic, but regarded by Prof. M'Coy, on the 
evidence of the few fossil plant impressions found in them, as of Triassic or 
Lower Mesozoic aspect. These fossils consist of several species cf Garnja- 
mopteris , and are of the fern family. They arc figured and described in 
Professor M'Coy’s Trodronius of Victorian Palaeontology, Decade No. II.” 
(13.) 1884. Murray (R. A. F.) The Carbonaceous Rocks of Victoria. Report of Progress, 
Geol. Survey Victoria, No. VII, pp. 78, et seep 
The Carbonaceous rocks of Victoria arc stated to be unmistakably 
referable to the Mesozoic Era, and with tolerable certainty to the Oolitic or 
Jurassic (Middle Mesozoic) Epoch, excepting the Bacchus Marsh Sandstones, 
whose fossil plant* impressions present a Triassic or Lower Mesozoic aspect. 
* I must state that the fossils alone, being of the genus Gan/gamopteris, would not be able to decide this 
age. It was only by the similarity of conglomeratic beds, in the Hawkeslmry rocks and in the Talchirs in 
India, that these three were correlated ; and as I thought that the Talchir-Karharbari present a Triassic aspect, 
I assumed it for the Bacchus Marsh beds also.
