Abstract


The new material of chitons and cuttlefish from the Korytnica Clays (Middle Miocene, Badenian; Holy Cross Mountains, Central Poland) is presented to supplement the data on some species, especially those established formerly as new ones (BAŁUK 1971, 1977). In chitons, a special attention is paid to the taxonomical problems resulting from diverse judgements in the literature (LAGHI 1977) upon the relations between some Neogene (Miocene and Pliocene) and present-day species. In cuttlefish, discussed are some morphological details of the fragmented sepions belonging to the formerly established species Sepia sanctacrucensis BAŁUK.
