Abstract : 30 species of the archaeogastropod family Trochidae are described from the Campanian of the southern Pyrenees, 15 of them are new. The new genus Amphigibbula is introduced and the genus Chilodontoidea is renamed as Hudledonta. Apparently several trochid lineages with living species can be traced back into the Late Cretaceous. This regards the Eucyclinae, Margaritinae, and Solariellinae, and the Tegulinae with some reservations. Among the groups examined here, only the members of the Trochinae appear to be of rather different character than their modern representatives. The fossil record of the Umboniinae can go far beyond that of the Late Cretaceous and connect even to Palaeozoic genera. The 15 new species are: Eucyclomphalus reminiscencius, Calliotropis torallolensis, Calliotropis seguris, Ilerdus pyrenaeus, Eucycloscala cretacea, Hudledonta nicolae, Danilia kosslerae, Margarites kasei, Margarites nielseni, Margarites kowalkei, Tectus quinteroi, Thoristella marshalli, Suavotrochus ponsi, Ethalia vinxae, and Protorotella herberti.
