deposits at Mornington and Grice's Creek, on the opposite side of 

 Port Phillip, with which horizon its fossil contents correlate it. 

 Out of 203 species of molluscs identified by us, only 26 (which 

 are marked in our list with a dagger) are not included in the 

 lists relating to the Mornington beds by Messrs. Hall and 

 Pi-itchard in the last volume of this Society's Proceedings.^ 



(4) These blue clays become finally mixed with a coarse water 

 worn quartz gravel, and cease to be fossiliferous. 



We are indebted to Messrs. Pritchard and Hall for assistance 

 in the identification of some of the molluscs and to Mr. 

 J. Dennant, F.G.S., for naming the corals. "We have also to 

 thank Mr. Coop, of North Williamstowm, for having placed at 

 our disposal a small collection of some of the larger forms which 

 have added a few useful names to our list. 



So far as possible we are depositing the specimens on which 

 our identifications are based (including those given by Mr. Coop) 

 with the National Museum. Other specimens have been lodged 

 with the Geological Museum of the University. "We have in 

 addition a very large number of other forms which we are unable 

 to identify as named species.
