the process of impregnation and to clarify the possible allochtonous occurrence of the mollusc shells (ROTARIDES, 1942; KROLOPP, 1967; SZÓNOKY, 1968).

Finally I thank Dr. Endre KROLOPP (Hungarian State Geological Institute) for providing the study material and for his assistance during the preparation of the manuscript. H W \ 1 1 6.7 l
