No attempt is here made to subdivide the two series 
of the Victorian Silurian, designated by Prof. J. W. Gregory as 
Melbournian and Yeringian* "it was evident, during the pro- 
gress of the present work, nevertheless, that several horizons can 
eventually be defined, after further detailed work has been done, 
by conjoining the stratigraphical and palaeontological data!
