REMARKS

Bourguignat attributed the name to “Letourneux, mss”. However, it is not clear that Letourneux alone was responsible for both the name and the nomenclatural act satisfying the criteria of availability (ICZN 1999b: art. 50.1.1), so authorship is Bourguignat alone. There is nothing in the original description that allows definitive identification of this shell as type material. However, the old label is in Bourguignat’s hand and favoured purple ink, and on this basis we consider this to be a syntype.
