ON SOME AUSTRALIAN TERTIARY CORALS. 195 
The — of the observations contained in the foregoing 
i are 
. That we have no Caryophyllia living or fossil in the Austra- 
ae seas or rocks. 
. That we have three well marked and peculiar forms of 
Saray ge 
hat we have two species of Sphenotrochus, one of which is 
still existing 
4. That we e have two fossil analogues of our living Conocyathus 
ep ae latter is supposed to be identical with a European 
iocen 
5 . we have a fossil form of the Cretaceous genus 
Smilotrochus i in our Miocene rocks. 
a new species of Gonceenitia with only two cycles. 
I may add also that, in a monograph I am preparing of our 
Npatealina living corals, I shall have occasion to describe two 
new species of ‘Deltocs yathus, one very similar to D. viola, and 
several species of Paracyathus, “Balonephaliig Eupsammia, §e.
