| Abstract |
Three new genera of the superfamily Seguenziacea are proposed. Hadroconus is erected for two western Atlantic and one western Pacific species formerly assigned to Basilissa Watson, 1879. Another species, Basilissa lampra Watson, 1879, is here made type-species of the monotypic genus Rotellenzia . One specimen from the syntype series of Carenzia carinata (Jeffreys, 1877) from the North Atlantic Ocean is a juvenile of Basilissa munda Watson, 1879, which is here established as type-species of Asthelys new genus; Basilissa simplex Watson, 1879, is also assigned to this genus. Shells of Hadroconus altus (Watson, 1879), Rotellenzia lampra (Watson 1879), and (Watson, 1879), are described and illustrated by SEM micrographs and/or light photographs. Comments on utility of shell and radular characters for generic definitions are presented. |
