Amphidromus adamsii subunicolor Fulton, 1896

Amphidromus adamsi var. subunicolor Fulton, 1896a: 82, pl. 5, fig. 5.

Type locality.

Banguey Island [Sabah, Malaysia].

Type material.

Lectotype NHMUK 1896.6.13.46 (Fig. 15A; H=30.1 mm, W=16.8 mm).

Remarks.

Fulton attributed the authorship of this variety to von Martens (1867: 357). However, von Martens only describe this varietal form with a letter " Bulimus adamsii var. D.", which is not a valid name ( ICZN 1999: Art. 11.9). Later " subunicolor " was appropriately described and figured in Fulton (1896a). The basal lip or bottom of the aperture of the lectotype was damaged and so the shell height given here is much smaller than the actual specimen size.
