Ebridians and actiniscidians from DSDP Leg 90 sites

Ebridians and actiniscidians are described from Sites 588, 591, and 594 in the southwest Pacific. The middle Miocene to early Pliocene interval at Site 591 can be subdivided into five ebridian-actiniscidian zones. These are correlated to standard nannoplankton zones. Five new species are described from the Neogene of the southwest Pacific: Ammodochium serotinum, Hermesinum obliquum, Actiniscus flosculus, A. laciniatus, and A squamosus.
