Type locality.

Amboyna [Ambon Island, Maluku Province, Indonesia].

Type material.

Lectotype (design. n.) NHMUK 20170352/1 (Fig. 1E), paralectotypes NHMUK 20170352/2-3 (2 shells; Fig. 1F).

Remarks.

The original description lacked mention of an operculum and did not include an illustration, and only one set of shell measurements was given. Pfeiffer (1854a) re-published the description and figured the species which no operculum. There is a lot of four shells from the Cuming collection with two Pfeiffer handwritten labels. The larger label states "C. Amboinensis Pfr.", "The operculum shows that …” and the collection locality from "Isle of Lobok". We presume that this lot contains a subsequently introduced specimen that has an operculum. Therefore, the specimen with an operculum attached (NHMUK 20070352/4) is excluded from the type series. The remaining three shells have no operculum and the smaller label states "Cycl. Amboinense Pfr." and gives the collection locality as “Amboyana”. The specimen that most closely matches with the measurements given in the original description and the illustration in Pfeiffer (1854a) is here designated as the lectotype to stabilise the name.
