XVI.—A_ Description of some Fossil. Corals and Echinoderms 
from the South-Australian Tertiaries. By P. Martin Dun- 
can, M.B. (Lond.), F. & Sec. Geol. Soc. 
[Plates V. & VI.] 
THE interesting simple Corals about to be described came from 
Muddy Creek and the Murray beds, and the Echinoderms from 
the latter locality *. The forms are more interesting, as yet, 
zoologically than geologically ; for very little can be determined 
from them concerning the age of the beds whence they were 
derived. The great Australian Tertiary formation is not of one 
age, but the fossils from Muddy Creek and the Murray give part 
of it a synchronism with the Upper Miocene and older Pliocene 
of Europe, and with the latest Miocene Coral-beds of the West 
Indies. Very probably the Tertiaries of Java, described by 
Mr. Jenkins +, and those whose Echinoderms have been studied 
by Herklots{, are of the same relative age.
