Material — One specimen. Kiscell-1. borehole, 83 m, Budapest, Óbuda. The lower part of the Tard Clay Formation, Lower Kiscellian. The specimen has broken after taking the photo.. Dimensions — 0.7 mm, width 0.3 mm. Diagnosis — The test is a biserial one. The chambers are slighdy inflated. Their number is 8-10 per side. The sutures are horizontal, parallel to each other. The height and width of the chambers are equal. The wall is agglutinated with calcareous portions. The aperture is a low arch at the base of the arx^rtural face. Remarks — It had been lost from the Hantken Collections. SZTRÁKOS (1982) gave the exact definition and taxonomical position for this species. Stratigraphical range — This species is very rare (HANTKEN 1875a, b). It could be found in the lower part of Clavulina Szabói layers, near Császár-fürdő, Buda. Recently one specimen has been found in the lowermost part of the Tard Clay Formation, Lower Oligocène. It is rare also in the Buda Marl, Upper Eocene (SZTRÁKOS 1987). Ecology — It is an epifaunal detritivore, clinging on hard substrates normal marine, cold water of the bathyal region (MURRAY 1973, 1991). It is sporadic in bathyal marl and clayey marl sediments.

Lectotype — GELLAI-NAGY (1988), pL L figs 4-5. Paralectotype — Budapest, Ujlak, Kiscell Clay Formation, Upper Kiscellian. The specimen has broken after taking the photo. Type locality — Budapest, top of the Kis-Sváb-hegy. Type level — Buda Marl Formation, Upper Priabonian. Material — One specimen remained in the Flantken Collections in Hungary. E>imensions — Length 1.5 mm. Diagnosis — The test is elongate, large, oval in section. The chambers ordered biserial, increasingly added. The wall is agglutimted, not so finely. The sutures are distinct, horizontally. The aperture is a short slit above the base of the arx^rtural face and surrounded by a lip. Remarks — riANTKEN (1868) described this species on the basis of a single specimen. Subsequendy, he succeeded in œUecting some further specimens in a sample from the Neustifter Zidegschlag (Ujlak, brickyard) from Kiscell Clay. Stratigraphical range —Plecanium elegáns is a very rare spedes (riANTKEN 1868, 1975 a, b), cxxurring in the Buda Marl Formation, Upper Eocene and in the Kiscell Clay, Upper Kiscellian. No specimens have been found recendy. Ecology — There are no data for its distributions in the Recent seas. Sparse fossil occurrences are known in bathyal marl and clay formations. 1871 1872 1875a 1875b 1889 1936 Family Valvulinidae BERTHELIN, 1880 Subfamily Valvulininae BERTHELIN, 1880 Genus Cylindroclavulina BERMÚDEZ & KEY, 1952 Cylindroclavulina rudilosta (HANTKEN, 1875) (Plate I: 10, Plate II: 10) Clavulina cylindrica — HANTKEN, p. 98.
