Genus Casmaria H. Adams & A. Adams, 1853
Buccinum vibex Linnaeus, 1758 (= Casmaria erinaceus (Linnaeus, 1758)) (by subsequent designation in Harris 1897)
Casmaria ponderosa has a long and complex synonymy, which has recently been comprehensively analyzed by Beu et al. (2012). All relevant type specimens were tracked down or proven to be lost. The syntype of Cassis torquata Reeve, 1848, illustrated earlier by Abbott (1968), was designated as the lectotype and also as the neotype of Buccinum ponderosum Gmelin, 1791, B. nodulosum Gmelin, 1791, Phalium quadratum Link, 1807, Buccinum biarmatum Dillwyn, 1817, Buccinum pantherina Dillwyn, 1817, and Cassis tenuilabris Menke, 1828 ( Beu et al. 2012: 78). For this reason, none of these names can apply to the new species we describe.
