Some critical notes about the introduction of the subspecies Zonaria pyrum nigromarginata Deprez & Govaert, 2009 (Mollusca: Gastropoda: Cypraeidae), pp.14-15, pl. I-XII, by Frank Nolf

Turritella nzimaorum Ryall & Vos, 2010 a junior synonym of Turritella caelata Mörch in Dunker, 1858, p. 28-29, pl. I-III, by Frank Nolf & Johan Verstraeten

Recently,P.Ryall& C. Vos (2010) described a new species of Turritella from western Africa. This species was compared with other similar representatives of the genus Turritella but the authors failed to notice the existence of Turritella caelata Mörch in Dunker, 1858 a species from the Gulf of Guinea with the same characteristics as those of T. nzimaorum Ryall & Vos, 2010. Because of the unmistakable likeness with the type and the original figures of T. caelata, the name T. nzimaorum is rejected as taxon.

Keywords: Mollusca, Gastropoda, TURRITELLIDAE, Turritella caelata, Turritella nzimaorum, junior synonym.
