ABSTRACT OF PROCEEDINGS. xvii. 
Tenison-Woods’ Thala marginata from Table Cape is transferred 
to Cordieria, under the name C. conospira, the name Borsonia 
(Cordieria) marginata being preoccupied. The species occurs 
abundantly in the Eocene in Tasmanian, Victorian and South 
Australian localities. Fossarus refractus is a new species from 
the Eocene of Table Cape, Tasmania. Dissochilus vitreus is a 
new species, described from the Miocene of Muddy Creek, and 
D. eburneus, from the Eocene of Muddy Creek, near Hamilton, 
is also described for the first time. Infwndibulum latesulcatum 
is a new species from the Eocene of Table Cape. Subemar- 
ginula occlusa is a new species from the Eocene of Victoria 
(Muddy Creek and Mornington). Puneturella hemipsila is 
described as new from the Eocene of Table Cape. Atlanta fossilis 
is described as new from the Eocene of Cape Otway. The genus — 
Plicatula also has one species, viz.: P. ramulosa from the Eocene 
of Table Cape. Martesia elegantula is also described asnew. It 
is from the Miocene of Grangeburn, near Hamilton, Victoria, 
burrowing in coral (Plesiastrea ). 
In the Polyzoa, a synopsis is given of McGillivray’s work, this 
author being almost entirely responsible for the very large additions 
to the genera and species of our Eocene fauna. Prof. Tate also 
intimates that he has discovered a representative of Cerithiopsis, 
& genus not hitherto represented in our fauna. The following 
genera are described as new :—Streblorhamphus, Tate and Coss- 
mann—¥. mirulus, from the Eocene of Muddy Creek, Victoria, 
and $. obesus from Mornington being described. Cheleutomia, 
Tate and Cossmann—the new species described being C. subvaricose 
from the Eocene of Victoria (Muddy Creek, Mornington, Curlewis 
and Fyansford). 
Mr. Dennant’s appendix is prefaced by a brief resumé of recent 
work on Australian Tertiary Corals. He then proceeds to record 
two hitherto unrecorded genera for the Australian Tertiary Corals; 
se are represented by the species now described for the first 
time, viz.:— Paracyathus ostatus, from the Eocene at Red 
Bluff, Shelford, Victoria. Montlivaltia variformis, from the 
Eocene of Table Cape, Tasmania.
