Amphidromus enganoensis Fulton, 1896

Amphidromus enganoensis Fulton, 1896a: 71, pl. 6, fig. 11.

Type locality.

Engano Island, West Sumatra.

Type material.

Lectotype NHMUK 1896.6.13.40 (Fig. 7E; H=50.5 mm, W=29.2 mm).

Remarks.

The original description was based on more than one specimen and three sets of measurements were given. The unique type was not explicitly designated, and the single specimen that remained in Fulton’s collection could not be implied to be the unique type (ICZN 1999: Art. 74.6). The “holotype” referred to in Laidlaw and Solem (1961) is explicit with a unique indication that constitutes a valid lectotype designation. Therefore, this specimen should be recognized as the lectotype to stabilise the name.
