Cyclophorus lingulatus (Sowerby I, 1843)

Cyclostoma lingulatum Sowerby I, 1843b: 64. Sowerby I 1843c: 126, pl. 29, figs 208-210. Pfeiffer 1849: 168, pl. 26, figs 6-10.

Cyclophorus lingulatus - Reeve 1861: sp. 49. Kobelt 1902: 114. Kobelt 1907: 573.

Type locality.

Island of Siquijod [Siquijor, Philippines]; Deleguete, Zebu Island [Cebu Island, Philippines]; Sibonga, Zebu Island [Cebu Island, Philippines]; Loboc, Bohol Island [Loboc, Bohol, Philippines]; Argao, Zebu Island [Argao, Cebu Island, Philippines].

Type material.

Lectotype (design. n.), NHMUK 20110272/1 from island of Siquijod ( Fig. 12F; D =21.3 mm, H=16.9 mm, W= 4½), paralectotypes NHMUK 20110272/2-3 (2 shells; Fig. 12G; D =20.9 mm, H=17.5 mm, W= 4½; D=20.0 mm, H=17.2 mm, W= 4½).

Remarks.

The original description included eight varieties indicated as "var. a" to "var. h.", based on samples from various localities sampled by H. Cuming and cites an illustration in "Thesaurus Conchyliorum part 3, pl. 30, fig. 208". This illustration matches the specimens in Cuming collection labelled as "var. a". Therefore we believe this implies that "var. a" is the type series of Cyclostoma linguiferum s.s. and the specimens labelled as "var. b" to "var. h" 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, fig. 208) is here designated as the lectotype.

Measurements of specimens in the lots previously recognized as "var. b" to "var. h" are given here for future reference:
