Aporrhais serresianus, Mich. 18. Cerithium metula, Lov. 19. Columbella haliaeti, Jeffr. It now appears that Fusus costulatus of Cantraine, to which this species had been referred by Italian conchologists, as well as lately by myself, belongs to the genus Pleurotoma, together with his Fusus semicostatus. The former species is in all probability P. striolata of Scacchi, and the latter is certainly (from Cantraine's type) P. maravigna of Bivona. The type of Cantraine's Fusus costulatus has been unfortunately lost. Under these circumstances I must retain my name haliaeti. Buccinum acutecostatum of Philippi = B. testa of Aradas is allied to the present species; but it is not, in m y opinion, identical with C. haliaeti. 20. Cylichna alba, Brown. All these species, except the last and those which are new, have an extensive range in the North Atlantic. Station 13. Warm area. 1. Amussium hoskynsi, Forb. 2. Lima subauriculata, Montagu. 3. Lima subovata, Jeffr. |
