NOTES ON A COLLECTION OF TERTIARY LIMESTONES. 
This sand consists chiefly of quartz grains (well-rounded) and 
rolled shell-fragments in about equal proportions, together with 
fragmental remains of polyzoa, echinoids, and a few worn tests of 
foraminifera. Of the last-named group, the following species, all 
common to the beaches of the southern coast of Australia, were 
recognised : 
Miliolina vulgaris, d’Orb. sp. 
Miliolina tricarinata, d’Orb. sp. 
Discorbina dimidiata, Jones and Parker. 
Pulvinulina repanda, Fichtel and Moll sp. 
Polystomella crispa, Linn. sp.
