The greatest number of species was found in Sabaudia and Fusaro lakes. Ficopomatus (= Mercierella) enigmaticus (Fauv.) was particularly abundant in oligo- to polyhaline lagoons, where generally it is the only recorded species of Serpuloidea; in euhaline lagoons it is replaced by Hydroides dianthus (Verr.) and H. elegans (Hasw.), sometimes together with Pileolaria pseudomilitaris (Th.-Quiev.), Vermiliopsis striaticeps (Gr.) and Janua pseudocorrugata (Bush.). J. pagenstecheri (Quatr.) and Pomatoceros lamarckii (Quatr.) were found only near the sea mouths. Morphological and taxonomical notes are also given.
