-Silicified Middle to Late Eocene shallow water sandstones outcropping in the Lower Murchison District near Kalbarri township contain a silicified fossil fauna including foraminifera, sponges, bryozoans, solitary corals, brachiopods, echinoids and molluscs. The known molluscan fauna consists of 51 species, comprising 2 cephalopods, 14 bivalves, 1 scaphopod and 34 gastropods. Of these taxa three are newly described, Cerithium lvilya, Zeacolpus bartol1i, and Lyria lamellatoplicata. 25 of these molluscs are identical to or closely comparable with taxa from the southern Australian Eocene. The occurrence of this fauna extends the Southeast Australian Province during the Eocene from southwest Western Australia along the west coast north to at least 27°present day south latitude; consequently the province is here renamed the Southern Australian Province.

-Sixty species of Bivalvia, representing 28 families and 41 genera, are recorded from three outcrops of the Karai Formation (Uttattur Group, Cauvery Basin) near Odiyam village, Tiruchirapalli district, south India. Both Kunnam and Odiyam Members of the Formation are represented in the study material. An undifferentiated Cenomanian age is assigned to the fossil assemblages.All species are described as fully as preservation and representation allow. Twenty three are redescribed with revised taxonomy. Newly described and named are the following 17 species: Nuculana (N
