About the presence of Limaria rotundata (Sowerby G.B. II, 1843) (BIVALVIA: PECTINOIDEA: LIMIDAE) off the coast of Angola, pp.22-24, plates I-VI by Frank Nolf.

For the first time, Limaria rotundata (Sowerby G.B. II, 1843) is mentioned as living in West Africa, namely in the coastal waters of Angola.
