Two new species of Columbellidae (Gastropoda: Buccinoidea) from the Cape Verde Archipelago

A new species of Anachis and another one of Mitrella (Gastropoda:  Columbellidae) from the Cape Verde Archipelago are described. The paucispiral protoconch of both of them indicates a non-planktotrophic development. The new species seem to have a distribution restricted to the Archipelago and are compared with other related West African columbellids.
