on the Pliensbachian brachiopods in 1968. In a preliminary note (VÖRÖS 1970) I listed a part of the fauna. In the present paper I revise and improve many of my earlier determinations after examination of the internal morphological features and after comparative studies of the Jurassic brachiopod collections in Vienna, Padua, Pisa and Palermo. LOCALITIES The geographical distribution of the 31 Pliensbachian brachiopod localities studied is shown in Fig. 1. (In a few cases, certain close localities of little importance have been grouped together and figured as single points. ) In the majority of the localities the detailed collection has been made by the Hungarian Geological Institute; their geology and sedimentology was described by KONDA (1970). A very precise ammonoid biostratigraphy was Fig. 1 Pliensbachian brachiopod localities in the Bakony Mts. 1. Városlőd, Kopasz-hegy (Határárok section); 2.
