a low trochospire; rapidly growing, inflated. Sutures depressed, right and oblique on the dorsal surface, arched, subradial on the ventral one. Umbilicus very small, usually filled by sediment. Aperture a low arch on the last chamber, with a big, flap-like lip extended over the entire aperture. Aperture extends from the umbilicus to the equatorial rim. It is extraumbilical. Bee cell like pattern is faintly discernible on the surface. Note, Differs from Globigerina eocaena and Globorotalia opima chiefly in the number of chambers in the last whorl. Occurrence. Most abundant in the Cylindroclavulina cylindrica Zone of the Buda Marl; less common in the beds underlying the Tard facies. It seems to be absent from the Kiscell Clay. Budapest region, Bükk Mountains foreland. Globigerina cf. senilis Bandy (Plate IV. 21/a-c) Globigerina ouachitaensis Howe et Wallace var. senilis Bandy, 1949 B.F. Ellis, A.E.

Test small; two whorls are to be seen; the last one has 3 1/2 to 4 chambers. Test shape in dorsal view quadrangular. Dorsal surface slightly convex. Chambers gradually growing, less rapidly in the last whorl. Last chamber usually smaller than the previous one. Sutures depressed, right, radial on the dorsal surface, slightly arched and radial on the ventral one. Umbilicus small, deep, quadrangular, exposes the aperture of the penultimate chamber.Aperture arched, symmetric, rimmed by a thin, rim-like lip along its whole length. It is intraumbilical. Test wall thin, finely perforated.
