preservation of Nucubidze's (1949) specimen is not very good and it is also largesized. The specimen of Uhlig's (1879) second figure (pi. 4., fig. 2.) is probably not S. albertii, because of the well-defined planareas. Distribution: According to Aimeras (1964) Salgirella albertii is Sinemurian in age. Its occurrence in the Pliensbachian is uncertain. The specimen of the Bakony Mts. is of Hettangian age, thus extends the global range of this species, (N.B. Almeras treated S. albertii v&r.lobata separately, which is Hettangian to Sinemurian in age). The species was reported from the Eastern Alps, the Southern Alps, the Northern Appennines, Algeria, the Caucasus and the Transdanubian Central Range. Rhynchonellida sp. 1. (Plate I: Fig. 3; Text-fig. 4) Material: 1 brachial valve from Szesztra-hegy. Dimensions (mm): Specimen M.93.6. (Text-fig. 4) length: 12.6, width: 15.0 (incomplete). Description - External characters: Medium-sized shell, subtriangular in outline. The sides of triangle are straight, the base of triangle is probably convex. The angle between the laText-fig. 4: Drawing teral margins is about 100°. The two corners are rounded at of Rhynchonellida the anterior margin. The width is larger than the length, sp. l, Szesztra-begy The brachial valve is slightly convex, but the convexity is very low. The maximum width is situated at the anterior third. The surface of the brachial valve is costate, 14 rounded, flat costae run straight to the anterior end. internal characters: The internal characters were not studied due to the paucity of the material. Remarks: Only a brachial valve was found but it characteristically differs from the other rhynchonellids. C. ? plicatissima has got more and sharper costae and its valve is more convex. S. cf. albertii is much more convex and it has got few and very sharp costae. Rhynchonellida sp. 2. is very different in shape. The incomplete preservation render a more precise identification impossible. Rhynchonellida sp. 2. (Text-fig. 5) Material: 1 incomplete specimen from Szesztra-hegy. Dimensions (mm): Specimen M.93.7. (Text-fig. 5) length: 10.7, width: 8.9, thickness: 8.5. Description - External characters: Small shell, rounded triangular in outline. The sides of triangle are very convex, the base of triangle is less convex. The angle between the lateral margins is about 85°. The two corners are rounded at the anterior margin. The length is larger than the width, while the Text-fig. 5: Drawing thickness is slightly smaller than the width, of Rhynchonellida Biconvex form, the convexity of the pedicle valve is larger sp. 2, Szesztra-hegy than the brachial one. The maximum width is situated at the
