Extensive material originating from different sources is currently examined by the author for a review of Mediterranean and northeastern Atlantic Muricidae. As a result, three species are here described as new. Ocenebra brevirostra n. sp. is the species usually figured as O. torosa (Lamarck, 1816) in literature. It is reported from the Atlantic coast of Morocco, and recognized as distinct from O. erinaceus (Linnaeus, 1758). Ocinebrina leukos n. sp. is a species with a uniformly white or dirty-white, lanceolate, heavy shell with a high spire, broad axial ribs, and a small, paucispiral protoconch. It is reported from Lanzarote Island, in the Canary Archipelago, and is compared with O. edwardsi (Payraudeau, 1826) from which it differs in being larger and very stable in form, sculpture and colour, unlike the highly variable shell morphology of O. edwardsi. ?Muricopsis cevikeri n. sp. is included in a group of species whose shell has reduced or obsolete second abapical cord, and is doubtfully included in the genus Muricopsis Bucquoy & Dautzenberg, 1882. It is reported from West Turkey and Cyprus, in the eastern Mediterranean Sea.
