Diagnosis: This is the description of this genus in POWELL (1979): "Shell rather large for the family, thin, auriliform, with very rapidly increasing whorls, the periphery angled or carinated; umbilicus very wide and perspective. Aperture large, D-shaped, very oblique, its top edge greatly in advance of the lower edge; columella edge straight".

HEDLEY (1913) described Naricava in substitution of Aaeorbis angasi (Adams & Angas, 1864) and placed it in Adeorbidae. THIELE (1929: 174) considered Naricava a synonym of Cochliokpis. WENZ (1938: 643) mentioned it as a subgenus of Cochliokpis, also placing it in Tornidae ( Adeorbidae). More recently, POWELL (1940) described a new species, Naricava neozelanica, and (POWELL, 1979) also considered it as a valid genus of Tornidae. PONDER (1994) observed live animals of Naricava angasi and concluded that it is a Vanikoridae and for this reason it must be removed from Tornidae. Our personal observations on species of Macromphalina and Macromphalus (Vanikoridae) from the west African coast, showed us an animal very similar to a those of Tornidae in its general appearance but with a very different radula. Since the radula described for the West African species which we placed in Naricava correspond to the appearance of those described for Tornidae, we provisionally keep Naricava in this family until future anatomical studies of this species confirm or refute its pertaining to Vanikoridae.
