Mangelia vauquelini ( Payraudeau 1826)

( Fig. 18 )

Pleurotoma vauquelini Payraudeau 1826: 145–146 , pl. 7, figs 14–15.

Materials: 08.05.2002, Salih Island (Bodrum), Aegean Sea , sand, 9 m, 1 spm + 1 sh. ( ESFM- GAS/2002-37 ) ; 20.09.2005, Ovacık (Mersin Bay), Levantine Sea , sand, 5 m, 1 sh. ( ESFM-GAS/2005-106 ) .

Remarks: M. vauquelini has a shell with a multispiral protoconch and sculpture of thick orthocline axial ribs (on the body whorl 9–10 ribs) and slim spirals, evident mostly between the axial ribs. Adult specimens have a thick labial varix and a posterior sinus of medium depth.

The species is characteristic with its shell shape and wide brown stripe on the body whorl below the suture.

According to Scarponi & Della Bella (2010:59), although the species (as well as M. taeniata which is discussed above) is traditionally attributed to genus Mangelia , it should at least to be considered doubtful due to the similarities of some protoconch and teleoconch characters with those of the genus Lyromangelia . But later the genus Lyromangelia was synonymized with the genus Mangelia (Bouchet et al. 2011) .

Distribution: Eastern Atlantic Ocean and Mediterranean Sea ( Cachia et al. 2001). Turkish Coasts: Levantine Sea, Aegean Sea and Sea of Marmara (Özt̹rk et al. 2014)
