Deltocyathus Italicus, Ed. and H.

Abstract

I FIND that Prof. Ralph Tate, F.G.S., President of the Adelaide Philosophical Society, has lately written as follows in an anniversary address. “On the other hand the Geelong coral, Deltocyathus italicus, Ed. and H., better known from the Italian Miocenes, is considered by Count Pourtales and Sir Wyville Thomson to be specifically distinct from its living analogue inhabiting the deep waters of Florida—an opposite, opinion to that held by Prof. Duncan.” During the last conversation I had with the late M. de Pourtales he informed me that after having seen and studied the Italian types, he was satisfied that I was correct in the statement I had made regarding the specific identity of the Tertiary and recent forms.
