Remarks.

Sowerby did not state on how many specimens he based himself. The specimen found was figured by Reeve and the label is evidently based on the information given by him. The material is considered as possible syntype; see Breure and Ablett 2011: 2-12 for historical details on the Cuming collection and the relationship with Sowerby’s and Reeve’s taxa.

Bulimulidae , Naesiotus eschariferus (Sowerby I, 1833).
