nor have I been able to detect, among the numerous collections 
which have passed through my hands, distinct evidence of 
any but doubtful examples of those foliated rocks which belong 
to the so-called Primary epoch. In Southern Australia, also, 
there does not appear to be any considerable amount of strata 
which could be referred to this epoch. 
Lower Paeozoic Rooks, 
Of these there are undoubted evidences in some limited dis- 
tricts of Tasmania, whilst in New South Wales and Queensland 
considerable areas are occupied by them. 
e greater mass of them, in the two latter provinces, 
appears to belong to Upper and Middle Silurian ; the mud- 
Stones of Yarralumla, with Encrinurus and Calymene; the 
Coralline and Pentamerus beds of Deleget and Colalamine ; 
the Tentaculite and Halysites beds of Wellington and Cavan ; 
and the beds with Calymene, Encrinurus, Beyrichia, and others 
with Illoenus, Harpes, Bronteus ; Brachiopoda, including Stro- 
phodonta and Radiata embracing Star-fishes, point to the exis- 
tence of at least the Upper Silurian formation on both flanks of 
the southern part of the Cordillera. There are also numerous 
corals included in the list given by me in the Southern Gold 
Fields (p. 285), which also confirm the same determination ; 
and it may be added that the above, and other fossils of this 
age mentioned by me elsewhere, have been examined by Pale- 
ontologists of eminence in Europe. Such are the genera Fa- 
vosites, Coenites, Ptychophyllum, Calamapora, Syringopora, 
Emmonsia, Alveolites and Cystophyllum, &. These, perhaps, 
might not alone satisfy a doubt, but with them occurs Recep- 
taculites ; since 1858, when these were determined, I have 
detected Halysites, which may settle the question as to Upper 
Silurian. Wenlock beds seem to be well developed on the
