Osteology of the Zeiformes from the Menilite Beds (The Carpathian flysch) is discussed. The genus Antigonia (Caproidae) and Zeus jaber are for the first time found to occur in the Carpathians. Zenopsis sp. from the Carpathians is a junior synonym of Z. clarus Daniltshenko from the Caucasus. Osteological characters of Zeus hoernesi show that it should be assigned to the genus Zenopsis. Osteological description of Capros radobojanus (Caproidae) from the Carpathians is given and a new species of C. medianus (Caproidae) is described. Comparison of osteological characters suggests that Capros medianus was not an ancestor of Capros aper; both species may have developed from a form close to Capros radobojanus.

Key words: Teleostei, taxonomy, Oligocene, Polish Carpathians.
