The last whorl is composed of 3 large subglobular chambers, wall calcareous, finely perforate, surface pitted. Sutures strongly depressed, slightly curved on the dorsal side, straight radial on the ventral side. Umbilicus wide, open. Aperture a large arch, ihteriomarginal

7, Taramsa section. Stratigraphie range: This species was first described by PINLAY (1938) from the middle Eocene of New Zealand. BOLLI (1957) recorded G. linaperta from the Paleocene till the upper Eocene of Trinidad. H0RNIBR00K (1958) found this species in the middle Eocene of New Zealand. BLOW & BANNER (in Eames et al, 1962) described this species from the Paleocene to the upper most Eocene, Lindi area, east Africa. NAKKADY (1959) identified this species as G. triloculinoides from the Paleocene of the Kharga Oasis, Western Desert, Egypt. Mc. TAVISH (1966) recorded G. linaperta from the upper Eocene of the Malaita group, British Solmon Islands, Remarks : Globigerina linaperta PINLAY differs from G. trilocu linoides PLUMMER by the more compressed chambers, which increase moderatly in size, and by the aperture which extends laterally to cover the previous chambers.
