1. This paper discusses the sedimentary, igneous and metar 

 morphic rock* of Moorooduc, in the Mornington Peninsula, 

 Victoria. 



2. Tte previous literature on the area is discussed. Chrono- 

 logically arranged, the salient features so far as they bear on 

 this communication aire as follow : — 



1856. Selwyn finds a oast of an eucrinite stem on Sand- 

 stone Island, Western Port, and indicates the age of 

 the older sedimentary rocks of the district as Silurian 

 on his geological map. 



1900. A. E. Kitson suggests a lithoLigical resemblance 

 between the older sedimentary rocks of Moorooduc 

 and the L. Ordovician rocks of Lancefield. He also 

 notes the localization of the micas in the acid veins 

 from the granite to the walls of the intrusion. 



1900. Evelyn G. Hogg describes petrologically the granite 

 rocks of areas adjoining Mt. Eliza. Some are de- 

 scribed as " granitite," others as " syenite."
