PULMONATA, SOLEOLIFERA

Veronicella Blainville, 1817 (Simroth, 1891; Sarasin & Sarasin, 1899; Pelseneer, 1901; Robbins & Cockerell, 1909; Colosi, 1922; Baker, 1925a, b, 1926, 1931; Grimpe & Hoffmann, 1925; Hoffmann, 1925; Coifmann, 1934a, b, 1935, 1938; Lanza & Quatrini, 1964a, b; Simroth, 1913; Thomé, 1975; Tillier, 1980, 1984) (According to Thiele: Vaginula = Vaginulus = Meisenheimera = Veronicella ). (1) The shell is probably not heterostrophic (Robertson, 1985). (43–51) We accept here the topology of the visceral loop {Pl(SbAbSp)Pl} (Coifmann, 1934a, b; Van Mol, 1967) and we do not accept here the topology which has been described by Hoffmann (1939): {Pl(Pa(SbAb)Sp)Pl} because parietal ganglia have not been anatomically observed. (52–53) Dorsal bodies that cannot be observed externally (Pelseneer, 1901; Van Mol, 1967) are supposed to be present here. (56) Fertilization pouch either present (Lanza & Quattrini, 1964a, b) or absent (Baker, 1925a, b; 1926; 1931). (67) Eggs of the spawn are joined by a ‘filamento mucozo’ (Lanza & Quatrini, 1964a, b), which is analogous with a chalaze, because of a distinct anatomy.
