Material examined.

Lectotype. Formosa, coll. Swinhoe (NHMUK 1871.1.20.9/1), new designation, 10.1 × 16.5 mm, whorls 4.5.

Paralectotypes. Formosa, coll. Swinhoe (NHMUK 1871.1.20.9/2-8, 7 shells). Taiwan, Formosa, from collection of H. Adams (NHMUK 1878.1.28.22, 3 shells).

Remarks.

The lot NHMUK 1871.1.20.9 was registered and labelled as "Cyclotus formosensis", but was later published as Cyclotus taivanus . Nine specimens were registered, but only eight were found. The specimen corresponding well in size with the measurement of Adams (1870) is designated as the lectotype for the stabilization of the name (ICZN 1999: Art. 74).
