termination of the same bone. ‘Ten teeth are preserved in the 
maxillary bone. Another block contains the outer side of the right 
mandibular ramus, with teeth, and with some other fragments. In 
a third block is the anterior part of the left mandibular ramus, with 
portions of the teeth. These remains were described in detail; and 
in conclusion the author discussed the bearing of these and other 
Megalosaurian remains upon our knowledge of the structure of that 
animal and its affinity to existing Reptilia, and criticised some of the 
evidence on which the relationship of the Dinosauria to birds is 
inferred—a relationship which he had suggested in 1841, but upon 
grounds which appeared to him to be more satisfactory.

‘Fossil Chilostomatous Bryozoa from Muddy Creek, Victoria.’ 
By A. W. Waters, Esq., F.G.S. 
In this paper the author described a collection of fossil Bryozoa, 
collected and sent over by Mr. J. Bracebridge Wilson, of Geelong. 
The collection is from Muddy Creek, Bird Rock, and Waurn Ponds, 
Victoria, and is of the so-called “ Miocene” age. There are 64 
species, of which 28 are known living; and 18 of these are now 
found fossil for the first time; but of the rest a large number have 
previously been found and described from Curdies Creek, Mount 
Gambier, and Bairnsdale. The author considered that 28 out of 
this number being known living is a large proportion, seeing that 
although our knowledge of the Australian recent fauna has been 
much increased during the last few years, it yet is very imperfect. 
The collection furnished 13 species of Catenicella, of which 5 at 
least are known living; and the author indicated the great importance 
of a thorough study of the living species of that genus. A notch 
in the aperture simulating a sinus seems sometimes to be replaced 
by asuboral pore; anda plate on the front of the cell requires further 
investigation. 
Three species are believed to be identical with fossils from the 
European chalk.

West Australia, north of the Gascoyne River.” By W. H. Hudles-

This collection was forwarded to England by Mr. Forrest, who has 
been engaged for some time past in surveying the northern portion 
of the colony, and was accompanied by a map indicating the positions
