Type locality.

Unknown.

Type material.

Lectotype (design. n.), NHMUK 20110231/1 ( Fig. 22A; D =32.1 mm, H=28.2 mm, W=6), paralectotypes NHMUK 20110231/2-3 (2 shells; Fig. 22B; D =28.0 mm, H=25.5 mm, W=6; D=30.4 mm, H=26.2 mm, W=6).

Remarks.

The original description of this species included seven varieties indicated with "var. a" to "var. g" from the Cuming Collection. Latin and English descriptions associated with illustrations were then published in the "Thesaurus Conchyliorum" ( Sowerby I 1843c). None of the subsequent authors recognized or used these seven varietal names. Two further works provided illustrations of the species from the Cuming coll. ( Pfeiffer 1848: pl. 8, figs 13-16; pl. 16, figs 17-20; Reeve 1861: sp. 25a, b; 8 fig. 30). These subsequently published illustrations match the specimens in the Cuming collection labelled as "var. a". Therefore we believe this implies that "var. a" is the type series of Cyclostoma tigrinum s.s. and the specimens labelled as "var. b" are distinct variants and are therefore excluded from the type series of this nominal species ( ICZN 1999: Art. 72.4.1). The specimen of "var. a" illustrated by Sowerby I (1843c: pl. 29, figs 201, 202) is here designated as the lectotype.

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

"var. b." NHMUK 20110232 from Guimaras Island [Philippines] (3 shells; D=30.5 mm, H=26.5 mm, W=6; D=28.0 mm, H=26.6 mm, W=6; D=27.2 mm, H=22.3 mm, W=6).
