• Calcarina spengleri (Gmelin) and Baculogypsina sphaerulata (Parker and Jones) are common reef-dwelling species of Foraminifera of the tropical Pacific. They are found, at places separately and at places in association, as major constituents of many beach sands around the islands of the western Pacific. Six shallow borings into reefs and outcrops on five islands give evidence of the existence of one or both species in the late Tertiary and Pleistocene of the equatorial Pacific between about 170°W. and 120°E. Both species seem to have first appeared in the western Pacific probably late in the Tertiary. In Recent sediments they are commonly found within the area from the Great Barrier Reef of Australia to the Philippines and Ryukyus on the west and from the Marianas to the Marshalls, Gilberts, Phoenix Islands, Samoa, and Niue on the east.
