Cyclophorus linguiferus (Sowerby I, 1843)

Cyclostoma linguiferum Sowerby I, 1843a: 31. Sowerby I 1843c: 125, pl. 29, fig. 198. Pfeiffer 1849: 168, pl. 23, figs 1-3.

Cyclophorus linguiferus - Reeve 1861: sp. 23a, b.

Cyclophorus validus var. linguifera - Kobelt 1902: 121.

Type locality.

Lobock, insulae Bohol [Loboc, Bohol, Philippines].

Type material.

Lectotype (design. n.), NHMUK 20110269/1 from Loboc, Bohol Island, Philippines, ( Fig. 12D; D =35.4 mm, H=31.5 mm, W=5), paralectotypes NHMUK 20110269/2-3 (2 shells; Fig. 12E; D =33.1 mm, H=26.6 mm, W=5; D=31.1 mm, H=26.9 mm, W=5).

Remarks.

The original description included three varieties indicated with "var. a", "var. b" and "var. c". Sowerby I subsequently published Thesaurus Conchyliorum ( Sowerby I 1843c) with Latin and English descriptions and associated illustrations. Pfeiffer (1849: pl. 23, figs 1-3) and Reeve (1861: sp. 23a, b) published illustrations of the species, however, neither author recognized or used the three varietal forms. These subsequent illustrations are matched with the specimens in the 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" and "var. c" 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 in Sowerby I (1843c: pl. 29, fig. 198), and closest to the dimensions given in the original description is here designated as the lectotype.

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

"var. b." NHMUK 20110270 from Loboc, Bohol Island [Philippines] (3 shells; D=32.6 mm, H=29.3 mm, W=5; D=32.1 mm, H=28.0 mm, W=5; D=30.1 mm, H=25.4 mm, W=5).

"var. c" NHMUK 20110271 from Loboc, Bohol Island [Philippines] (1 shell; D=30.3 mm, H=27.3 mm, W=5).
