Remarks.

The original description was published by Sowerby I in 1843 and included and illustation. Later, Pfeiffer (1849) and Reeve (1862) re-published the description and figured this species based on material from the Cuming collection. The NHM collections contain a lot of four shells from the Cuming collection with original labels giving only the taxon name. However, the collection locality "Flores (Martens in litt.)" has been subsequently added. The specimens in the Cuming collection matches well with the illustration in the original description, especially in regard to the dark brown reticulated pattern and dark spiral band on the periphery of last whorl. However, Sowerby I (1843a) did not explicitly state that the species description was based on specimens from the Cuming collection. Therefore, we consider this lot to be possible syntypes.
