The barnacles collected in dredges and grabs from stations in and off the Straits of Gibraltar (BALGIM 1984 cruise) which were sorted at CENTOB in Brest, are systematically considered. A few other deep sea barnacles are also considered. Of the eighteen species illustrated, three are new to science. Particular attention is given to species of Scalpellinae with eleven species (two new), and Verrucidae with four species (one new). This paper determines only the species and their biogeography, leaving aside questions of generic categorisation, phylogeny, and the particular ecological and hydrological circumstances of each cruise.
