Lectotype — GELLAI-NAGY (1988), pl. IV, figs 1-7. Paralectotype — M.99.43. Kis-Sváb-hegy, Buda Marl Formation, Upper Eocene. Type locality — Budapest, Buda, Császár fürdő. Type level — Buda Marl Formation, Upper Eocene. Material: — 202 specimens were in the Hantken Collections in Hungary (Table 4). Dimensions — length is 2-A mm, width 0.6-1.0 mm. Diagnosis — The test is elongate, triserial in the early ontogenetic stages, later uniserial, and triangular in section. The wall is aggjiutinated, relatively thick and solid. The aperture rounded, terminal and central in the adult stage, and may occur on a small neck. Remarks — It is one of the most characteristic form of the Clavulina Szabói layers (riANTKEN 1864, 1866a, b, as Rhabdogonium Szabói; 1868, 1875a, b). On the basis of the occurrence of this species HANTKEN (1866a) wrote: "... the Buda Marl and Kiscell Clay (Kis-czelli tályag) are of the same in age, Oligocène". Stratigraphical range — Tritaxia szabói is a common species, being the most characteristic foraminifer in the lower and upper part of the Clavulina Szabói layers (HANTKEN, 1868; 1875a, b). riANTKEN collected specimens from many occurrences (Table 3). In Hungary, this species ranges from the Middle Eocene to the Early Miocene (NAGYNÉ GELLAI 1973; SZTRÁKOS 1978, 1979, 1982; KORECZNÉ LAKY & NAGYNÉ GELLAI 1985; OZSVÁRT 1999) and charaaeristic in the Buda Marl and Kiscell Clay, but it cxxurrs in the Upper Oligocène and Lower Miocene formations, too. In the Central Paratethys, it ranges from the Middle Eocene to Middle Egerian (POPESCU & IVA 1971; SlKIC 1985; ClCHA et al. 1998). In Ukraine it occurs from Middle Eocene to the Lower Oligocène (KRAEVA & ZERNECKTJ 1969). In South Bulgaria, it ranges from Upper Eocene Paleocene to Lower Oligocène (DARAKCHIEVA 1999). In the Aquitanian basin it ranges from the Middle Eocene to the Oligocène (CU

VÏÏTTF.R & SZAKÁLL 1949). In Italy this species occurs in the Upper Eocene (HAGN 1956; BRAGA & GRÜNIG in BRAGA et al. 1975). Ecology — Tritaxia szabói is a typical euhalin form, frequent in the bathyal sandy clay and sandy fades together with bathyal agglutinated and calcareous taxa, such as Reticulopbragmium, Planulina, Heterolepa.

—Budapest, Ujlak Type level

—Kiscell Qay Formation, Upper Kiscellian Material — Two specimens remained in the Flantken Collections in Hungary. Dimensions

—length 2.5 mm, width 13 mm Diagnosis — The test is subconical and trochospirally coiled in early ontogenetic stages. The number of the inflated (hambers is five per whorl Subsequently, the number of chambers per whorl reduced to three. The wall is finely aggliitinated with calcareous particles. The ar^rture is a low sht near the base of the apertiiral face A narrow Remarks — "The generic attribution of the spedes is doubtful. A canaliculate wall has not been proved", wrote RÖGL (in QCHA et aL 1998), on the basis of the specimen, stored in NHM (Wien) Collection. The figured specimen is collected from the Kiscell Qay, Budapest, Mátyás-hegy, Holzspach brickyard, coll. T. BÁLDÍ). Stratigraphical range — It is sparse in the Qavulina Szabói layers IdANTKEN (1875a, b), mainly in the Kiscell Clay. SZTRÁKOS (1979) found the figured specimen in Ujlak, in the Kiscell Qay Formation. Fa the Central Paratethys it ranges from the Upper Eocene to the Egerian (QCHA et al. 1998). Ecology — It is an infaunal, cktritivore form, living under cold water condition in normal marine, fine sediment bathyal fades (MURRAY 1973,1991).
