VÖRÖS, A., SZABÓ, J., DULAI, A., SZENTÉ, L, EBLI, O. & LOBITZER, H. Palaeontological notes Prionorhynchia flabellum (MENEGHINI in GEMMELLARO, 1874) (Plate VI: 1-3) — Five specimens were found at three collecting points. This species is similar to P. greppini but it can be distinguished by a wing-like widening; its pedicle valve is flat and the brachial valve is slightly convex. The Schafberg specimens are smaller than the well-preserved Mondsee material. The figured P. flabellum shows stronger uniplication than the known specimens in the literature (e.g. CANAVARI (1880) or PARONA (1880)). Prionorhynchia greppini (OPPEL, 1861) (Plate VI: 4-6) — Twenty

7 six specimens were collected at several localities. It can be distinguished from the similar P. polyptycha by the smaller number of the ribs and from the triangular Cuneirhynchia palmata by the rounded outline. The planareas are sometimes deep and the lateral commissures slighdy rise from the planareas. Some Schafberg specimens are unusually convex, these are similar to BÖSE & SCHLOSSER's figure (1900, pi. 18. fig. 12a). Detailed systematic description of this species was given by DULAI (1992 and in press). Prionorhynchia guembeH (OPPEL, 1861) (Plate VI: 7-9) — TWrteen specimens were found at five collecting points. It generally occurs in small number (one or two specimens), with the exception of the Mondsee locality, where it is relatively frequent. Our specimens are not so elongated as figured by BÖCKH (1874) and GEYER (1889) but they are similar to OPPEL'

s (1861) samples. The Schwarzensee and the Mondsee specimens have few but strong ribs and very deep planareas. They sometimes show high uniplication. A similar species was described from Hungary as "R." forticostata by BÖCKH (1874). This latter species has fewer ribs at the anterior margin but it has more and smaller ribs near the beak. Prionorhynchia ? hagaviensis (BÖSE, 1898) — Only four specimens occured at three collecting points. This species was described from Kramsach and Schafberg by BÖSE (1898) but it was also mentioned from other areas (e.g. KULCSÁR 1914 from Hungary). A similar form was found in the Early Liassic formations of the Gerecse Mts, which was identified as "Rlynchonella" triquetra (T3ULAI in press). P. ? hagaviensis has larger size and its outline is more angular. The Mondsee specimen is small, flat and triangular, while the material found above the Schafbergalpe is larger with bifurcated ribs (10) and its outline is not so angular. BÖSE (1898) mentioned fewer ribs (5-7). The generic identification of this species is uncertain: SlBLÍK (2002) classified it into Pisirhynchia with question mark. Prionorhynchia polyptycha (OPPEL, 1861) (Plate VI: 10—12) — Thirteen brachiopods were found at four localities. Some of them are large and wide with verydeep planareas, however the figured specimen is smaller and not so wide. BÖHM et al. (1999) and SlBLÍK (2002) regarded this species synonymous with Cuneirhynchia fraasi. This opinion is not followed in this paper, moreover on the basis of the differences between the ribs, the beak ridges, the planareas and the plication, this species was classified into a different genus. Detailed systematic description of this species was given by DULAI (1992 and in press). Prionorhynchia pseudoscherina (BÖSE, 1898) — This species was described from the Schafberg area by BÖSE (1898) and it was also found at three different points along the slopes of the Schafberg during our field works (fourteen specimens). Its valves are rather convex with few rounded ribs. Two similar species are P. forticostata and P. guembeli. The former has more numerous ribs at the beaks but the number of ribs decreases towards the anterior margin. The latter has larger and sharper ribs. Both species show larger and deeper planareas. Cirpa briseis (GEMMELLARO, 1874) (Plate VI: 13-15) — Five specimens were collected at Mondsee. BÖSE (1898) mentioned this species from Kramsach and Hinterschafberg. It has few ribs (8-10), the uniplication is high, the brachial valve is sometimes flat and the outline shows sudden widening from the beak. Sometimes difficult to distinguish from Cirpa variabilis, because this latter species was shown in the literature as very variable and widely interpreted species. Cirpa ? latifrons (STUR in GEYER, 1889) (Plate VI: 1618) — It was found at two collecting points of the Schafberg slopes (5 specimens). The reliable generic classification of this species is not yet available: SACCHI VlALLI & CANTALUPPI (1967) mentioned as member of Prionorhynchia while. SULSER (1993) used Fissirhynchia with question mark. Recendy Cirpa with (or without, e.g. in SlBLÍK 2002) question mark have been used by several authors (e.g. VÖRÖS 1997; BÖHM et al. 1999; DULAI 1992 and in press). The Schafberg specimens are more convex than the Hungarian Lókút material. The uniplication is strongly asymmetrical at the Schafberg specimens. The Schafberg material is very similar to GEYER's (1889) figures. The number of ribs is higly variable both amongst GEYER's (1889) Hierlatz brachiopods and the recently collected Schafberg specimens. This species was described in detail from the Hungarian Hettangian and Early Sinemurian formations (DULAI 1992 and in press). Cirpa planifrons (ORMÓS, 1937) (Plate VI: 19-20) — Only two specimens were found at two localities. This species was described from the Bakony Mts by ORMÓS (1937) but meanwhile it was also mentioned from the Austrian Alps (Steinplatte: SlBLÍK 1993, Adnet: BÖHM et al. 1999). A closely related form was found in the Hungarian deeper water Hettangian formations (Tata, Kálvária-domb; Cirpa aff. planifrons: DULAI in press). C. fronto shows very similar form but this latter species has fewer ribs, which are evenly strong throughout the whole valves, while the ribs become gradually stronger towards the anterior margin in C planifrons.
