Liospiriferina alpina (OPPEL, 1861) (Plate VI: 41-43) — One hundred and eighteen specimens were found at fourteen collecting points. This species is missing only at one locality, where the specimen number was rather low. L alpina was the most frequent taxon during our field work. It is similar to L. brevirostris but its brachial valve is not so flat, the beak of the pedicle valve is not so curved and the length is larger than the width. Detailed systematic description was given by DULAI (1992 and in press). Liospiriferina angulata (OPPEL, 1861) — Ten brachiopods occurred at five localities. Similar species are L. obtusa and L. darwini, where the beak of the pedicle valve is not so pointed as in L angulata. Our specimens are very small-sized at the railway station terminal and Suissensee localities but larger along the Schafberg slopes. Detailed systematic description was given by DULAI (1992 and in press). Liospiriferina aradasi (GEMMELLARO, 1878) (Plate VII: 1—3) — Eight specimens were found at four collecting points. This species is similar to L. pichleri, but the beak of the pedicle valve is wider, more elongated and very

7 high. L pichleri shows a small sulcus, which can be followed from the anterior margin to the beak of the pedicle valve. Another similar species is L alpina, but the beak is quite stronger and more curved at L aradasi. This is the first record of this species from the Northern Calcareous Alps. Detailed systematic description is given by DULAI (in press). Liospiriferina brevirostris (OPPEL, 1861) (Plate VII: 4—6) —Five large-sized specimens were collected along the Schafberg slopes and at Mondsee locality

. This species is very similar to L alpina, but its beak is more curved and the brachial valve is flatter. In the absence of the brachial valve it is difficult to distinguish the two species. Its valves are sometimes slightly ribbed at the anterior margin. Detailed systematic description was given by DULAI (1992 and in press). Uospiriferina cordiformis (BÖSE, 1898) (Plate VII: 7-10) — Three specimens occurred at two localities. This species was described from Schafberg area by BÖSE (1898). Two brachial valves were found above the Schafbergalpe: they are ven

7 convex with not high but wide and strongly curved beaks. Both valves are very convex at the figured specimen, the brachial beak is large and strongly curved. The beak of the pedicle valve is broken, it is probably higher than the brachial beak. Width is larger than the lenght. Liospiriferina darwini (GEMMELLARO, 1878) (Plate VII: 11—13) — Sixteen specimens were found at five collecting points of the Schafberg slopes and at Mondsee. The Schafberg material generally consists of smallsized forms. The depth and the development of the sulcus is very variable at the studied specimens. L. sylvia is a similar form but these two species can be cüstinguished by the angle between the interarea and the comissures (45° at L sylvia and 85° at L darwini). Detailed systematic description is given by DULAI (in press). Liospiriferina gryphoidea (UHLIG, 1879) — This species occurred at one locality only but it can be found rather frequently at Mondsee (seventeen specimens). It is similar to L. brevirostris but the beak of the pedicle valve is more curved and the outline is more elongated. The Schafberg specimens are generally small- to medium-sized, elongated forms. This is the only brachiopod taxon in the studied material, which can be regarded as not fixed form but free living in the loose sediment. Detailed systematic description is given by DULAI (in press). Liospiriferina meneghiniana (CANAVARI, 1880) — Only one small-sized juvenile pedicle valve was collected at Mondsee locality. The small beak is very

7 high. It is similar to L angulata, but its beak is slightly curved and not so pointed. It was also mentioned from the Pliensbachian formations of the Transdanubian Central Range by VÖRÖS (1997) but it is the first record of this species from the Northern Calcareous Alps. Liospiriferina obtusa (OPPEL, 1861) (Plate VII: 14-17) — L obtusa is relatively frequent brachiopod taxon in the studied region: twenty-five specimens occurred at ten collecting points. A specimen found at the tunnel of Schafberg has rather pointed sulcus and it shows a transitional form to L. acuta. The beak of the Schwarzensee specimen is broken and probably slighdy convex, therefore its identification is uncertain. The sulcus of two Mondsee specimens are rather distorted but otherwise the forms are not deformed. At some brachiopods the beaks are nearly at the same heights; the beak of the brachial valve is wider and larger, while the beak of the pedicle valve is slightly pointed. Similar taxa are L, angulata and L sicula, distinguishing characters were described by DULAI (1992 and in press). Liospiriferina pichleri (NEUMAYR, 1879) — Only one very small juvenile pedicle valve was collected at Mondsee locality. This species is very similar to L alpina but a small sulcus developed from the beak and its beak is narrower. SlBLÍK (1993) mentioned the differences between the outlines and the short hinge line. The small uniplication shows an important difference between L. pichleri and L meneghiniana. Detailed systematic description was given by DULAI (1993 and in press). Liospiriferina rostrata (SCHLOTHEIM, 1822) — Only three specimens were found at one collecting point along the slopes of Schafberg. It is similar to L. alpina but it shows slight sinus and small uniplication. Fine ribs were frequently mentioned in the literature, but they are not observed at the Schafberg material. BÖSE's (1898) specimens from the Schafberg area are also smooth.
