Limacina Lamarck, 1819 (Pelseneer, 1887b ( Limacina = Spiratella ); Meisenheimer, 1905; Vayssière, 1915; Lebour, 1932; Hoffman, 1939; Gabe & Prenant, 1951, 1952b; Morton, 1954; Van der Spoel, 1967; Lalli & Wells, 1978; Lalli & Gilmer, 1989). (43–51) The highly concentrated nervous system (Pelseneer, 1887b) has two symmetrical pairs of cerebral and pedal nervous masses and one asymmetrical pair of visceral nervous masses, in which histological sections (Meisenheimer, 1905) did not allow identification of fused ganglia. We accept the hypothesis of Hoffmann (1939) here for the visceral loop ganglia {PlSb(AbdSp)Pl}.
Peraclis Forbes, 1844 (Van der Spoel, 1976; Pelseneer, 1887b; Meisenheimer, 1905; Vayssière, 1915; Lalli & Gilmer, 1989). (18) In accordance with Pelseneer (1887b) and Van der Spoel (1967), gill lamellae are considered here analogous with that of cephalaspideans. (43–51) The visceral loop of the highly concentrated nervous system is coded: {PlSbAbdSpPl} (Pelseneer, 1887b; Meisenheimer, 1905).
