Amalda

Gastropoda - Neogastropoda - Ancillariidae

Taxonomy
Amalda was named by Adams and Adams (1853) [Sepkoski's age data: K u R Sepkoski's reference number: 614]. It is extant.

It was assigned to Ancillinae by Wilson (1994); to Neogastropoda by Sepkoski (2002); to Olivinae by Harzhauser (2002); to Ancillariinae by Pacaud et al. (2013); and to Olividae by Harzhauser (2004), Darragh (2017).
