Adams & A. Adams, 1857 Round to modioliform, beaks more or less behind anterior end, anterior hinge margin thickened and vertically striated or with dysodont teeth, dorsal hinge margin usually finely vertically striated. Surface with radial sculpture commonly absent on median area or rarely smooth. Free living, nestling, rarely boring ( Soot-Ryen, 1969 ). Gregariella Monterosato, 1883 ( Fig. 1 ) Type species.

The probable syntypes of V. s p l e n d i d a (BMNH 1967564/1-3, negative 1623) have nothing to do with Gregariella but Volsella . Although referring to Dunker (1857) , Reeve’s description and figure of his Lithodomus splendidus (1858: sp. 31, pl. 5, fig. 31), is a member of a hairy Gregariella . Chenu’s figure (1862, fig. 775) is the same as Reeve’s and Kobelt’s figure (1881, pl. 106, fig. 10) is a redrawing of Reeve’s. Thus, Kobelt’s selection of splendida “Dunker” as type of Botula should be ruled out (see Type species problem). Keen (1971: 67, fig. 135) attributed Dunker’s species to Lioberus , noting “three specimens from the type lot in the British Museum, not previously illustrated ”. BMNH 1967564/1, the largest, 21-12-? mm, is among the figured in Keen (1971) , below the figure number 136.
