Abstract

Foraminifera indicative of the Terliary Lower e. Upper e, and Lower f ''Stages' of the East Indian Letter Classification ate recognized in the post-Eocene limestones of Christmas Island. The local ranges of Spiroclypeus globulus Nuttall (here regarded as a junior synonym of S. margaritatus), Miogypsina neodispansa (Jones and Chapman), Lepidocyclina (Eulepidina) ephippioides (J. and C.), and L. (E.) andrewsiana (J. and C.)—for all of which this small island is the type area —are determined. Five faunal assemblages are recognized, and one new species, Heterostegina barriei, described.
