168 RALPH TATE. 
Cliffs, the upper beds of the Muddy Creek section and the low- 
level fossiliferous beds around the Gippsland lakes, which last 
repose against the escarpments of the Hocene-limestones, well- 
exposed in the cliffs of the Rivers Mitchell, Tambo, &c. A marine 
fauna of Pliocene Age has been discovered and recorded by me in 
Trans. Roy. Soc. 8. Austr., Vol. xr, p. 172, 1890. 
An examination of the fossils of the Oamaru Series in New 
Zealand brings to light many previously unknown specific com- 
munities with our Older Tertiary ; and in the case of the echino- 
derms, the generic grouping is absolutely identical, though the 
species are for the most part different, which leaves no room to 
doubt that the Oamaru Series is correlative with the Eocene of 
this continent, and is homotaxially related to the lowest members 
of the European Eocene, if it be not somewhat older. 
The additions to the specific representatives of the various 
genera, recorded in my Census are too numerous to record here, 
but I have described an exemplar species of each of the majority 
of the genera now added. 
Class MAMMALIA. 
The skeleton of a marsupial is recorded by Mr. R. M. Johnston 
from the ‘“ Turritella beds” at Table Cape, and by him referred 
to the living genus Halmaturus without specific name. At the 
time of writing my Census, I had thought it possible that the 
specimen might be of recent date, and had reached its position by 
way of a vertical fissure from the surface, and it was accordingly 
omitted. During the meeting of the Australasian Association for 
the Advancement of Science at Hobart, the slab containing the 
skeleton was carefully examined by Professérs Hutton and Spencer 
and myself, and by us was unhesitatingly pronounced to be lying 
in the bedding plane of the rock. Subsequently Professor Spencer 
and myself visited Table Cape to study its stratigraphical features, 
with the result that this extensive vertical section represents one 
period of deposition, gradually passing from the basal conglomer- 
ates and coarse grits, rich in marine fossils, to the “ Turritella-—
