Clathurella Polignaci
''Clathurella'' is a genus of sea snails, marine gastropod mollusks in the family Clathurellidae. Description The shell is fusiform or turriculated. The columella lip has no callosity, except a small posterior tooth. There is no operculum. The surface is cancellated and has a more ventricose form, and a more evident siphonal canal. This distinguishes it from ''Mangelia''; the emargination of the outer lip from ''Clavatula''; the texture and sculpture of the surface from Bela and '' Daphnella.''
