On some Australian Tertiary Fossil Corals and 
Polyzoa. 
By the Rev. J. E. anyon la aa oe Hon. Mem. 
Roy. Soc. N.S. W, 
[Read before the Royal Society of N.S.W., 4 September, 1878. ] 
a year I published in the Proceedings of this Society (vol. 11, 
a description of some tertiary fossil corals from the 
Nudd Creek beds, Western Victoria. Since then I have found 
corals generally. In the first place I am or to signalize the 
discovery of a Monitlivaltia in our terti en i this is 
another link to that chain of facts which iam lary 
such a mesozoic aspect: I allude especially to yay rove esa of 
Salenia and Belemnites as the inga beds, nastrea 
Tsannanie, our simple endothecal corals generally, and Pleuroto- 
maria. wy aoe apne ei &e., among the mollusca. Most 
of these genera have probably livin ing representatives, though 
they were a their ate development long before the pany: of 
the tertiary period. Montlivaltia is a similar instance. 
genus was established by Lamouroux ee  Méthodique des 
in the jurassic or the chalk formations. There are about ten 
tertiary species known, but none living. The tertiary species 
are Eocene and Miocene. The forms of this coral vary very 
nical to discoid. 
which I draw attention belongs ; but it is *: discoid form which 
is flat or even concave beneath, and that is, I believe, rare in the 
genus. There is a fossil fa lately a by Mr. Tomes 
* This Trigonia is a kable i as it is so diff t fr our living 
species and so tike some mesozoic forms.
