tion to the coal-beds, contain one plant often of the size, shape, 
and reticulated neuration of the Glossopteris Browniana, but 
without the midrib. For this I have proposed the name Gan- 
gamopteris; and of this generic form a species, G. angustifolius 
(M‘Coy), occurs in New-South-Wales coal-plant beds along with 
the Glossopteris Browniana. 3 
In all the marine Australian Mesozoic fossiliferous beds which 
I have seen, the genus Trigonia is absent. 
TRIASSIC AND PERMIAN PERIODS. 
I was able to suggest the existence of Trias deposits in Aus- 
tralia from the muschelkalk genus Myaphoria, which I recog- 
nized in some fossils from Wollumbilla sent by Mr. Clarke ; 
and the Permian I suggested to exist at Mantuan Downs, also 
in New South Wales, from the Producte and Aulesteges of that 
period submitted to me in the same collection. se 
CARBONIFEROUS PERIOD. 
The sandstones of the Avon in Gippsland are the only traces 
of this formation that I can recognize in Victoria ; ‘and the only 
fossil I have seen from it is the Lepidodendron referred to above, 
identical with that recognized by me many years ago from New 
South Wales, and which I have lately seen also from Queens- 
land. 
DEVONIAN PERIOD. 
It is with great pleasure I announce the fact of my having 
been able satisfactorily to determine the existence of this forma- 
tion also in Australia, the limestone of Buchan in Gippsland 
containing characteristic corals, Placodermatous fish, and abun- 
dance of the Spirifera levicostata, perfectly identical with speci- 
mens from the European Devonian Limestones of the Eifel. 
UPPER SILURIAN PERIOD. 
I have been able to recognize the Mayhill Sandstones and the 
Wenlock rocks with certainty in many localities in Victoria. 
At Broadhurst Creek, for instance, the beds are filled with 
numbers of the Phacops (Odontochila) longicaudatus, exactly as 
the corresponding English beds of Cheney Longville are in Shrop- 
shire; and here, as in every part of the northern hemisphere, 
the Spirifera reticulata is the commonest Brachiopod ; and many 
others identical with species of England, Bohemia, and North 
America occur with it. 
The Ludlow rocks are indicated by the Orthoceras bullatum — 
and a series of starfish closely representing those of the English 
Ludlow beds, together with a beautiful new Homalonotus (H.
