A classification of the Foraminifera adapted from Mr. H. 2. 
Brady’s “ Notes on Reticularian Rhizopoda”’ is given (p. 1x), and a 
table (p. xiv) showing their range in time, thus aifording a gencrai 
view of the occurrence and succession of the most important genera 
from the Silurian epoch to the present time. 
A combined geologico-geographical arrangement is adopted in 
this Catalogue, with the view of aiding both a special and compre- 
hensive study of the fossil Foraminifera and allied Rhizopods pre- 
served in the British Museum, in which arrangement certain geo- 
graphical lines are followed, beginning with the British Islands, and 
going eastward, under the several geological headings, and then 
returning to the west for a new line, the successive stages of each 
geological system being noted in upward order. 
In the supplementary notes are some valuable remarks on the 
more important groups mentioned in the preceding part of the Cata- 
logue, as Hozoon, Leceptaculites, Fusulina, Orbitolina, Nummulites, 
and on the Foraminifera of the Chalk of England, of that of the 
north of Ireland, and also of the London Clay at Hampstead. 
A geographical index and an index of the genera and species are 
also given; so that it is hoped this Catalogue may be the means oi 
increasing the usefulness of this portion of the national collection.

GEOLOGICAL SOCIETY. 
April 26, 1882.—J. W. Hulke, Esq., F.R.S., 
President, in the Chair. 
The following communications were read :— 
1. “On Fossil Chilostomatous Bryozoa from Mount Gambier, 
South Australia.” By Arthur W. Waters, Esq., F.L.S., F.G.S. 
The author gave a descriptive list of 66 species of Bryozoa, be- 
longing to the suborder Chilostomata, from the colléction of the 
Geological Society and of Mr. Etheridge, Jun. ; of these, 15 were con- 
sidered to be new, 28 are now found living, of which 23 in Australian 
seas, 25 were found in the material previously described from 8.W. 
Victoria, 2 were considered identical with European chalk forms, 11 
with Miocene, 12 with Pliocene, and 21 have been found in a col- 
lection from Bairnsdale, Gippsland. 
Mr. Waters states that the collections in his hand from 8.W. 
Victoria, Mount Gambier, and Bairnsdale will together yield about 
200 species of Chilostomata and Cyclostomata.
