It now appears that Fus^^s costidatus 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. maravignce of Bivona. The type of 

 Cantraine's Fusus costulatus has been unfortunately lost. Under 

 these circumstances I must retain my name haliceeti. Buccinum 

 acutecostatum of Philippi = B. testes of Aradas is allied to the 

 present species ; but it is not, in my opinion, identical with 0. 

 halicBeti. 



20. Cylichna alba. Brown. 



All these species, except the last and those which are new, have an 

 extensive range in the North Atlantic.
