GEOLOGY. 
1. By Mr. B. Dunstan, F.G.S., &c. — A collection of 
fossils, among which were the following : — 
Graptolites (Hydrozoans) and Lingulocaris (one of the 
earliest representatives of Mollusca), from the Ordovician 
Rocks of Victoria. Several v^ell preserved of those interest- 
ing early forms of Crustacea — Trilobites (Encrinurus, 
Calymene Phacops, Hausmannia, &c.), from the Upper 
Silurian Rocks of X.S. Wales. Corals (Favosites, Helio- 
lites, Cyathophyllum, &c.), from the Upper Silurian Rocks 
at Chillagoe and Molong, N.S.W. A very interesting 
Brachiopod (Rhynchonella pleurodon), specially character- 
istic of the Devonian (Mt. Lambie) Rocks of X.S. Wales. 
Common forms of Brachiopods (Spirifera, Martiniopsis, 
Productus, &c.) ; Pelecypoda (Aviciilopecten Moenia, &c.) ; 
Gasteropoda (Platyschisma and Pleurotomaria) ; Pteropoda 
(Conularia); and of Cephalopods (Goniatites), from the 
Permo-Carboniferous Rocks, both of Queensland and X.S. 
Wales. Of Permo-Carboniferous Corals were the well- 
known forms Trachypora Wilkinsonii, from X.S. Wales, 
and Stenopora crinita from Gympie. Zaphrentis from near 
Rockhampton, and the new and interesting Lithostrotion, 
from Lion Creek, near Stanwell. Fenestella and Rhombopora 
laxa,from Gympie, were forms of Polyzoa from these rocks. 
Plants, characteristic of the P. Carb. beds of Eastern 
Australia, shown were Glossopteris, Gangamopteris, and 
Vertebraria. From Carboniferous Rocks were Rhacopteris, 
a beautifully well preserved specimen of the order Filices, 
and specially characteristic of these beds at Stroud, X.S.W. 
Large fossil fishes, some of which are still imdescribed, from 
the Wianamatta Shales (Triassic) near Sydney. Casts of 
vertebrge of a large Saurian (Plesiosaurus), from the 
Cretaceous Beds, near Lake Eyre, S. Australia. Tertiary 
Plants from X.S.W.; Fossil Xuts, from the deep leads at 
Gulgong, X.S.W., and Haddon, Victoria. Marsupials’ 
remains from the Post-Tertiary Beds of Queensland and 
and X.S.W. , including Diprotodon jaws, tusks, and teeth, 
a large sacrum bone of an extinct Kangaroo (Palorchestes 
Azael, Owen), from Wellington Caves, X.S.W., which must
