. .Some observations on larval life and barnacle settlement in the Port of Genoa are reported together with a key of the nauplii of the four species recorded in the Tyrrhenian coasts: Balanus amphiuite, Balanus perforatus, Balanus trigonus and Balanus eburneus. Weekly densities of naupliar stages for each species as well as the average percent reduction from one stage to the next until the cypris stage have been recorded. The amount of the latter is recorded both in plankton and along with settled barnacles on artificial substrata.
