Nesiohelix swinhoei , Kuroda 1941: 148.

Type locality.

Formosa [Taiwan] (Swinhoe).

Material examined.

Lectotype. Formosa, coll. Swinhoe, from collection of H. Cuming (NHMUK 20040585/1, large form), new designation, 42.7 × 75.3 mm, whorls 5.5.

Paralectotypes. Formosa, coll. Swinhoe, from collection of H. Cuming (NHMUK 20040585/2, 1 shell, large form, 50.9 × 68.1 mm, whorls 5.25; NHMUK 20040585/3-4, 2 shells, small form, 32.4-32.5 × 50.8-54.5 mm, whorls 4.75-5.0).

Remarks.

The shell sizes of these four specimens do not agree with Pfeiffer’s original measurements of 27-28 × 52-58 mm for the typical form and 25 × 46 mm for the minor form. I consider Pfeiffer’s measurements to be incorrect. The largest specimen is designated as the lectotype for the stabilization of the name ( ICZN 1999: Art. 74).
