Iskop. Foram. SSSE. Tr. Vnigri n. ser. 76. pp. 78-79. pi* 11. figs. 1 a-2 v, 6 a-7 V, 5 av, but not 3 a-4 vi Description. Test small, of two whorls, with four chambers in the last one. Trochospire high. Chambers Inflated, spherical. Sutures strongly depressed, right, radial. Umbilicus small, deep. Aperture situated on the last chamber, which is smaller than the previous one. It is an intraumbilical, high arch, with a scarcely discernible rim-like thickening. Note. Differs from the holotype in being more loosely col­led, from Globigerina ouachitaensis by its lower trochospire, and by the aperture of the penultimate chamber being not visi­ble in the umbilicus, and from G. praebulloides in the disposi­tion of the chambers, by its narrower umbilicus and by the not visible former aperture. Occurrence. Common in all horizons of the Buda Marl, but particularly so in the Oligocène part. Also present in the Kiscell Clay.
