Amphidromus lindstedti (Pfeiffer, 1857)

Bulimus lindstedti Pfeiffer, 1857c [1856]: 388.

Type locality.

Malacca.

Type material.

Lectotype NHMUK 19601448 (Fig. 10D; H=38.9 mm, W=18.4 mm).

Remarks.

Fulton (1896a: 85) described the type as being bleached in condition, and suggested that the specimen should have a color pattern if it were not bleached. We examined the lectotype but, in contrast, consider it to be entirely white in shell colour and not bleached. In addition, Laidlaw and Solem (1961) suggested that Amphidromus quadrasi Hidalgo, 1887 and Amphidromus versicolor Fulton, 1896 from the Philippines were probably junior synomyms of this species. With a unique straight columella, thickened parietal callus and elongated aperture, Amphidromus lindstedti (Pfeiffer, 1857) is clearly distinct from both speceis. However, new collections from precise localities will help elucidate whether this is a distinct species or a colour form of the other taxa.
