Mangelia Spadiana

''Mangelia'' is a large genus of sea snails, marine gastropod mollusks in the family Mangeliidae.

The genus has been used for a long time as a wastebasket taxon. There have been many described species, many of which have become synonyms. Among the remaining accepted names a good number are still in doubt and are little known. They are only tentatively placed within the genus ''Mangelia''.

This genus was named ''Mangelia'' by Leach and accepted by Risso in 1826. Later, some authors, such as Lovén in 1846, spelled it inadvertently as ''Mangilia'', to honor the Italian malacologist Mangili Giuseppe (1767-1829). This had led to some confusion.

Description

The shell has a fusiform shape. It is mostly longitudinally ribbed The spire is elongated, turriculated, acuminated. The lip is very finely rugosely denticulated. The lip is thickened and slightly sinuated at the upper part. The siphonal canal is short, more or less truncated. The columella is smooth. The sinus is near the suture. There is no operculum.

The genus ''Mangelia'' used to be defined by a multispiral protoconch, contrary to the genus ''Mangeliella'' Bucquoy, Dautzenberg & Dollfus, 1883 which was defined by a paucispiral protoconch. In 2011 the genus ''Mangeliella'' has been recognized as a synonym of ''Mangelia''.
