Type locality.

prope Montem Ophir, Malaccae [Gunung Ledang, Johor, Malaysia].

Type material.

Lectotype (design. n.), NHMUK 20120064/1 ( Fig. 22C; D =51.1 mm, H=35.7 mm, W=5), paralectotype NHMUK 20120064/2 (1 shell; Fig. 22D; D =48.1 mm, H=33.4 mm, W=5).

Remarks.

The original description of this species included two un-named varieties from the Cuming Collection. The NHM collection contain two lots from the Cuming collection with the original labels giving the taxon name, type locality and varietal names stated as "var. a" and "var. b". Latin and English descriptions associated with illustrations were then published in the "Thesaurus Conchyliorum" ( Sowerby I 1843c). Two further works provided illustrations of the species from Cuming coll. ( Pfeiffer 1849: 169, pl. 23, figs 10, 11; Reeve 1861: sp. 9). These subsequently published illustrations match specimens in the Cuming collection labelled as "var. a". We consider that this implies that "var. a" is the type series of Cyclostoma tuba s.s. and the specimens labelled as "var. b" are distinct variants and are therefore excluded from the type series ( ICZN 1999: Art. 72.4.1). The specimen of "var. a" illustrated by Sowerby I (1843c: 122, pl. 27, figs 129, 130) is here designated as the lectotype.

Measurements of specimens in "var. b" are given for future reference:

"var. b." NHMUK 20120065 from Mountain Ophir, Malaccae [Malaysia] (3 shells; D=50.4 mm, H=33.8 mm, W=5; D=50.1 mm, H=35.5 mm, W=5; D=48.1 mm, H=34.0 mm, W=5).
