(Fine, sandy desposit) 3. (rough, sandy deposit) 7. (fine, banded, greyish, yellowish clay). The 388 G. frumentum shells which formed the study material are deposited in the collection of the Hungarian State Geological Institute, Budapest. I was not in a position to take direct measurements of the fossil material because of the fragile condition of the shells. So I placed them on a 8x8 cm ribbed plate and after photography, I took the measurements from the photos, proportionated 1 to 1, with 0.1 mm precision (max 5% measuring error). It would be unreal to work with higher precision because of longitudinal
