Fossil bivalves and gastropods originating from a neptunian dike infilling are described from Central Italy. The fauna of Middle Jurassic age is composed of hundred of specimens. Among them we acknowledged 26 species from 19 genera. Parallelodon apenninicus, P. carsulanus and P. maxiai among bivalves are described as new. Among the gastropods the following new genera and species are erected: Proconulus (Laeviconulus) keratomorphus, Odoardia, O. prosornata, Fischeriella, F. umbra, Naticopsis (Marmolatella) esui, Neritoma (Neridomus) riettii, Crossostoma macerinoi, Planicollonia, P. macrostoma, Allocosmia geometrica.

Abstract
Fossil bivalves and gastropods originating from a neptunian dike infilling are described from Central Italy. The fauna of Middle Jurassic age is composed of hundred of specimens. Among them we acknowledged 26 species from 19 genera. Parallelodon apenninicus, P. carsulanus and P. maxiai among bivalves are described as new. Among the gastropods the following new genera and species are erected: Proconulus (Laeviconulus) keratomorphus, Odoardia, O. prosornata, Fischeriella, F. umbra, Naticopsis (Marmolatella) esui, Neritoma (Neridomus) riettii, Crossostoma macerinoi, Planicollonia, P. macrostoma, Allocosmia geometrica. The family Crossostomatidae Cox, 1960 is also emended.Pubblicazioni consigliate
