AbstractA large collection of fragmentary Mollusca from 203–215 m in a bore near Glenbrook Beach, south of Manukau Harbour, is from deeper in the bore than were previous collections from the area, and is correlated with the Opoitian fauna of Kaawa Creek, south of Waikato Heads. Faunas previously reported from bores south of Manukau Harbour by Schofield are all correlated with the Waipipian fauna of Otahuhu Brewery well.
