Not Valuta elongata Schroeter, 1804 {=lAurinia sp.); not Voluta 

 elongata Swainson, 1821 {=Alcithae swainsoni Marwick, 1926). 



It is strange that both Franc (1957, p. 152) and Solem (1961, 

 p. 477) use Martyn's name, even though in 1957 the "Universal 

 Conchologist" was officially rejected for nomenclatorial purposes. 

 Neither do they list the three subsequent, earUest names, those of 

 Lightfoot, Bruguiere, and Roding. Since the name fihratus is un- 

 available, the adoption of Lightfoot's name should prove acceptable,

The generic name Labyrinthus Beck, 1837, must yield to the earlier 

 name Lampadion Rodmg, 1798. Winckworth (1945, p. 141) lists as 

 type Lampadion labyrinthus Roding, citing Gray (1847, p. 173) as 

 authority for this type designation. Although Gray gave Helix otis 

 as the type of the genus, which was not one of the originally included 

 species, Winckworth's action is vahd ("International Code of Zoologi- 

 cal Nomenclature;" art. 69(a) (iv)), Wurtz (1955, pp, 106-107), 

 apparently overlooldng Winckworth's statement, designated as type 

 the same species of Roding, Lampadion labyrinthus, fixing this name 

 on the figure in Favanne (1780), cited by Roding, Wurtz then goes
