Notes on West African Perrona (Gastropoda: Clavatulidae), with the description of a new species

The type species of the genus Perrona is poorly known and given an erroneous type locality. One of the purposes of this paper is to clarify its status and correct spelling as well as illustrating the species and defining its distribution area. A new species from Angola belonging to this genus is described. The shell, protoconch, operculum and radula are illustrated, and the reasons for assigning this new species to this genus are discussed. All known species of Perrona are figured.
