... ). Frýda (1998) suggested that the Pragoscutulidae belongs to Caenogastropoda or Neritimorpha and noted some similarities of Pragoscutula wareni with species of the Jurassic Symmetrocapulus . The protoconch of Symmetrocapulus Dacqué, 1934 is not well known but seemingly consists of somewhat more...

... placement in the Neritimorpha Golikov and Starobogatov, 1975 is clear from its typical hemispherical shell and D-shaped inner lip with a row of denticles. Long considered linked to Recent Nerita Linnaeus, 1758 (see Wenz, 1938–1944 ; Kase, 1984 ; Squires and Saul, 1993 ; Bandel and Kiel, 2003...

... Platyceratoidea unites some gastropods belonging to the subclass Neritimorpha ( Bandel, 1992 ). In addition, new studies focused on the protoconch morphology revealed that the Platyceratoidea unites two long-lived groups of Neritimorpha with quite different protoconch morphology ( Frýda 1998a, 1998b, 1999...

... ). This morphology is also shown by stem members of extant clades such as the Caenogastropoda (Perunelomorpha) ( Frýda, 1999 ) ( Figs. 1D, 1E ) and Neritimorpha ( Bandel and Frýda, 1999 ) ( Fig. 1A ), whereas it is absent in all possible modern descendants of these clades. Openly coiled initial whorls are known...

... synonymized with Otostomia and Neritoplica , respectively, as discussed by Bandel and Kiel ( 2003 ) and Kiel and Aranda-Manteca ( 2002 ). A key to genera of the Neritimorpha accompanying the description of seven new species by Bandel and Kiel ( 2003 ) seems less able to distinguish between genera than...

.... In order to protect the embryos against various extrinsic factors, most recent gastropods (Caenogastropoda and Neritimorpha) lay capsule-enclosed eggs on a variety of firm and hard media (e.g., Pechenik 1982 ; Rawlings 1999 ; Przeslawski 2004 ; Aktipis et al. 2008 ; Bigatti et al. 2010 ; see Roche et...

... that anatomically dextral (or sinistral) animals occupy dextrally (or sinistrally) coiled shells. Conversely, hyperstrophy ( 3, 4 ) means that handedness of the shell and soft body is different. Coiling of all shell whorls in the same direction (e.g., Caenogastropoda and Neritimorpha) is termed homeostrophic ( 5...

... suggests the gastropod had a well-developed unidirectional inhalant current, possibly, but not likely, with a siphon. This well-developed inhalant sinus suggests that this genus was more advanced than the Vetigastropoda, possibly occurring as a sister group to the Neritimorpha or even the lower...
