Of the two Aplacophora taxa, we believe the neomeniolds are the less derived (Scheltema, 1993, 1996; Scheltema et al., 1994; Ivanov, 1996), and are thus particularly important in considerations of the phylogeny of molluscs.
Species were selected from the following collections of Aplacophora: West European Basin (INCAL, 15 July to 11 August, 1976, Centre National de Tri d'Oc6anographie Biologique [CENTOB]; and RV Chain Cruise 106, 15 August to 6 September, 1972, Woods Hole Oceanographic Institution); off Gibraltar (BALGIM, 25 May to 22 June, 1984, CENTOB); Bass Strait (Bass Strait Survey 1979-1984, Museum of Victoria, Australia); and Argentine Basin (RV Atlantis II Cruise 60, 10.iii-30.iii.1971).
