anterior third, while the maximum convexity is at the half of the length. There are no beak ridges and planareas. The surface of the shell is costate, 8-10 weak costae can be seen on the valves. The cross section of costae is rounded triangular. Internal characters: The internal characters were not studied due to the paucity of the material. Remarks: Only an incomplete specimen was found, which is infilled by coarse-grained sparry calcite, so the identification is impossible. However its characters are very different from the features of the other rhynchonellids.

Material: 1 incomplete specimen from Kávás-hegy. Dimensions (mm): Specimen M.93.8. (Text-fig. 6) length: -, width: 17.0, thickness: 11.0 (incomplete). Description - External characters: Medium-sized shell. The angle between the lateral margins is about 90°. Biconvex form, the pedicle valve is more convex, than the brachial one. The maximum width and the maximum convexity is situated at the anterior third. Text-fig. 6: Drawing The umbo of brachial valve is small and not pro- of Liospiriferina pichleri, minent. The beak is medium sized and strongly curved. Kávás-hegy The preservation of the region of the lateral interarea is not very good, so the interpretation is difficult. The anterior part of the specimen is missing but a prominent uniplication has already developed near the beak. Internal characters: There were no adequate specimens available for serial sectioning due to the paucity of the material. Remarks: The only specimen is rather fragmentary, but it can well be identified with Neumayr's species. The uniplication has already developed near the beak. Mancenido (1993) did not figure L. pichleri but he revised Renz's (1932) material, therefore his record was accepted in the synonymy. Mancenido (1993) mentioned some similar forms: Spiriferina alpina Oppel, 1861 and Spiriferina inventa De Gregorio, 1930. However L. pichleri has got a prominent sulcus and its beak is very narrow. Distribution: According to Aimeras (1964), L. pichleri is Hettangian to Early Sinemurian in age. The species was reported from the Northern Limestone Alps, Western Greece, the Central Appennines and the Transdanubian Central Range.
