The spheroidical test is densely perforated, the apertures are larger pore-like holes, delimiting slightly protruding portions from the surface of the test. The protruding parts do not alter the globelike form but if they are bigger, the test takes on a pear-like shape, that is, the younger chamber does not cover the older one in the usual degree, — this is B r a d y's so-called ,supplementary chamber" — but the two chambers may have identical or almost equal diameters and in this case it is the form C. biloba, to be found also in Markusevec. The apertures are observable not only on the protrusions — which are really the chamber walls or sutures — but irregularly also on other parts of the test. It occurs in rare and lucky cases that, within the broken, globular and youngest chamber, chambers of the older globigerina composition (mostly similar to the shape of 0. triloba) may, as if imbedded, be observed, on which the Globigerina-Uke aperture is invisible. (A similar phenomen has been observed in the case of Orbulina universa.) The Candorbulina are very frequent in the Tortonian deposits of the Carpathian's Basin, from Dés, Iza-völgye to Vát in the western Transdanubium. It may often be found in masses in the deposits of this age both on surface as in deep borings. Zsupanek Zsupanek lies north to Orsova, in the Tortonian calcareous clay of which (coming to the suface to the West of this locality) a Bulimina sp. n. had been found (3). This species was discussed by Franzenau in his note. Bulimina scalena Franzenau (Plate I, figs. 10, 11) 1894. Bulimina n. sp. — Franzenau, Természetrajzi Füz. XVII. p; 40. The test is the broadest at its lower third, its lower portion blunt-tipped, the upper one bent in an arch. The coils are made by elongated chambers, of which the last makes up threefourth of the test. The suturai lines run in small furrows. The slit-like aperture is at right angles to the upper edge of the last but one chamber. Its length is 0,5 mm. Rare. A similar form is Bulimina preoli Reuss var. pyrula D'Orbigny, figured by Parker and Jones in 1865. Romhány Franzenau discusses the fauna — but does not publish the figures of the new species (4) — originating from the Rupelian clay marge from 8 m depth of the municipal well of Romhány.
