Abstract
The evolution of the Globorotalia zealandica Hornibrook and G. miozea Finlay lineages is outlined and some morphologically distinctive elements of limited strati-graphic range are distinguished as new subspecies, namely:G. zealandica incognita, G. zealandica pseudomiozea, G. miozea conoidea, and G. miozea sphericomiozea. The material studied is mainly from the Gisborne area, on the east coast of the North Island of New Zealand.
