quartz pebbles. Ovei'lying the limestones, and apparently 

 conformable to them, is a series of unfossiliferous grey sands with 

 plentiful spangles of white mica up to a quarter of an inch in 

 diameter. These pass up into hard ferruginous grits which dip 

 to sea level on the east and cap the mesozoic rocks on the west. 

 Though apparently quite conformable to the high dipping Eocene 

 it is possible that these grits are much younger than they. If 

 they are Eocene then much of the inland gravel and grit capping 

 of the mesozoic with which they seem continuous will be far older 

 than Wilkinson considered it. The actual junction of the fossi- 

 liferous beds with the mesozoic is hidden by dinfting sand, and 

 over this the path to the beach passes. 



An examination of the list of fossils from this locality shows 

 that a number hitherto known only from Aldinga occur, while at 

 the same time the relationship to the Spring Creek lower beds is 

 pronounced ; in fact the Castle Cove section emphasises the close 

 faunal resemblance between Spring Creek and Aldinga. 



The fossils occurring are as follows : — 

 Corals. 



Flabellum distinctum, Edw. and Haime. 

 Echitwidea. 



Leiocidaris australis, Duncan. 



Cassidulus australite, Duncan. [(Echinobrissus) Type locality.] 



Eupatagus coranguinum, Tate. 



Hemiaster planedeclivis, Gregory. 

 Crinoidea. 



Pentacrinus stellatus, Hutton. 

 Brachiopoda. 



Terebratulina triangularis, Tate. 



Magellania pectoralis, Tate. 

 ,, insolita, Tate. 



,, tateana, T. "Woods. 



Crania quadrangularis, Tate. 



Terebratula aldingje, Tate. 

 Latnellibranchiata.
