(of verneuili d'Orb. type), Patellina Will., Pulvinulinella Cush., Pullenia P. and J. Nodosaria longiscata d'Orb. and cf. filiformis Renuss, Bulimina of the pupoides d'Orb. line (as quadrata Plummer), Gyroidina of the zelandica line. (b) Tapuwaeroa Series, North Island. Type locality not designated; by tautonomy should be somewhere in Tapuwaeroa Valley (see Ongley and Macpherson, 1928, p. 23), but insufficient macro- and micro-faunas are known from here as yet. The formation rests unconformably on the Clarentian Raukumara beds, and is overlain by unconformable Mangatu or by overthrust Taitai. The Whangai (Quennell, 1937, p. 3) is not here faunally separated, as there are few macro-fossils, the micro-faunas are poor, and the line of division uncertain. Some of the Foraminifera quoted below will probably be restricted later to a horizon above Tapuwaeroa—possibly a reconstituted Mangatu. Of this the Waipara greensands may be a South Island equivalent. Restricted forms:— (M) *Ostrea lapillicola Marw. (1926B, p. 381). (F) Ammodiscoides Cush. (reappears in Recent fauna), Conotrochammina (as whangaia), Rzehakina Cush. (as epigona Rze.), Bolivinoides Cush. (as dorreeni), Rotamorphina (as cushmani), Globotruncana n.sp.
