Distribution: According to Aimeras (1964) C. ? plicatissima is Late Hettan­gian to Sinemurian in age. Vörös (1983) found it ranging up to the Davoei Zone of the Early Pliensbachian in the Bakony Mts. The species was reported from Ger­many, Switzerland, the Eastern Alps, the Southern Alps, Sicily and the Transdanu­bian Central Range.

Material: 1 fragmentary pedicle valve from Lókúti-domb (leg.: A. Vörös). Dimensions (mm): Specimen M.93.5. (Text-fig. 3) length: 13.3, width: 13.0 (incomplete). Description - External characters: Medium-sized shell, rounded triangular in outline. The sides of triangle are straight or slightly concave, the base of triangle is very con­vex. The angle between the lateral margins is about 90°. The two corners are slightly angular at the anterior margin. The length is nearly equal to the width, but this is an incomplete of salgirella cf albertii specimen, so the total width is greater than the length. Lókúti-domb The pedicle valve is convex. The maximum width is si­tuated at the anterior third, while the maximum convexity is probably at the half of the length. There are no beak ridges and planareas at the pedicle valve. The la­teral commissures are probably straight, the anterior commissure is uniplicate. All the surface of the shell is costate , 9 very sharp costae run straight to the anterior end without bifurcation. Three of them are on the fold and 3-3 on its si­des. The cross section of costae is triangular. Internal characters: There were no adequate specimens available for serial sectioning due to the paucity of the material. Remarks: Only a fragmentary pedicle valve was found, nevertheless, the spe­cimen can be well identified with 5. albertii. The fold of our specimen is not so well defined. Geyer (1889) separated R. Alberti var. lobata, which is probably not distinguishable from typical S. alberti. Fucini (1895) mentioned some surprisingly large specimens (larger than 3 cm). Böse & Schlosser's (1900) specimen is very flat and it has got more costae on the fold than it is typical. On the basis of Princi­pi's (1910) and Dareste de la Chavanne's (1920) figures their specimens have got fewer costae and the costae are less sharp than it is at S. albertii in general. The
