N.Z. Geological Survey, Lower Hutt

Abstract Eleven species are described from five localities in Hawkes Bay, South Canterbury, and Otago. Six are new: Wetzeliella (Wetzeliella) tabulata, Kaiatan Stage; W. (W.) hampdenensis, Bortonian; W. (W.) echinosuturata, Porangan; W. (W.) edwardsi, Heretaungan and Mangaorapan; W. (W:) ornata, Mangao-rapan; and W. (Rhombodinium) waipawaensis, top Waipawan. The other five species have previously been described from overseas, four from Europe: Wetzeliella {Rhombodinium) glabra Cookson, a new variety of which is described, from the Kaiatan Stage; W. (Wetz.) coleothrypta Williams and Downie, Heretaungan and Mangaorapan; W. (W.) articulata Eisenack, Danne-virke Series; W. (W.) hyperacantha Cooks. & Eis., Waipawan; and W. (W.) homomorpha Defl. & Cooks., Waipawan and Teurian. Results indicate that the genus should prove very useful in the correlation of New Zealand and overseas Eocene and Paleocene strata. A peridinioid tabulation is demonstrated for W. (W.) tabulata and W. (W.) echinosuturata.
