Type locality.

Takow, Formosa [northern Qi-Jin, Kaohsiung City] (Swinhoe)

Material examined.

Lectotype. Formosa, coll. Swinhoe (NHMUK 1866.5.9.11/1), new designation, 13.7 × 19.4 mm, whorls 5.75.

Paralectotypes. Formosa, coll. Swinhoe (NHMUK 1866.5.9.11/2-3, 2 shells).

Remarks.

Adams (1866) described the locality as Takow, Formosa, but the original label has only "Formosa". The lot NHMUK 1866.5.9.11 was first registered and labelled as " Nanina propinqua ", then later published as Nanina assimilis . None of these shells exactly match with the measurements of Adams (1866). The specimen in the best condition is designated as the lectotype for the stabilization of the name ( ICZN 1999: Art. 74).
