Abstract: The present paper deals with the distribution of species within the genus Cymbium (Gastropoda: Volutidae) along the coasts of Angola from the mouth of the Congo River in the north to the mouth of the Cunene River in the south. Two known species occur in that area and a third, new one is described from the mouth of the Congo River, where it lives in a restricted distribution range.
