Remarks.

Godwin-Austen described this species based on material from A Everett. The NHM collections contain a lot of two shells from the A Everett collection with an original label stating “Type”. The specimen which corresponds to the illustrations and shell dimensions given in the original description, and marked with an “X”, is figured herein (Fig. 10B).

Godwin-Austen also described a varietal form "var. depressa" from "Molu Hills" based on specimens collected by Mr. Boxall, ex. R Hungerford collection. The type series of the taxa could not be traced in the NHM collections.
