Cyclophorus validus (Sowerby I, 1842)

Cyclostoma validum Sowerby I, 1842: 82. Sowerby I 1843c: 123, pl. 27, figs 132, 133. Pfeiffer 1848: 89, pl. 11, figs 9, 10.

Cyclophorus validus - Reeve 1861: sp. 23c, d. Kobelt 1902: 120. Kobelt 1908: 581.

Type locality.

Island of Leyte, island of Luçon, island of Samar and island of Mindanao, Philippines.

Type material.

Lectotype (design. n.), NHMUK 20110280/1 from island of Leyte ( Fig. 23C; D =47.9 mm, H=40.4 mm, W=5), paralectotypes NHMUK 20110280/2-3 (2 shells; Fig. 23D; D =46.7 mm, H=39.9 mm, W=5; D=44.0 mm, H=37.6 mm, W=5).

Remarks.

The original description of this species included four varieties indicated "var. a" to "var. d", without illustration from the Cuming Collection. Subsequent authors (including Sowerby I 1843b) did not recognise or use these varietal names. The NHM collections contain four lots of Cuming collection material with original labels giving the taxon and varietal names "var. a" to "var. d". The description and illustration in Sowerby I (1843b) match the specimens in the Cuming collection labelled as "var. a". We consider that this implies that "var. a" is the type series of Cyclostoma validum s.s. and the specimens labelled as "var. b", "var. c" and "var. d" 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: pl. 27, figs 132, 133), is here designated as the lectotype.

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

"var. b." NHMUK 20110281 from Tayabas Province, Luzon [Philippines] (3 shells; D=39.2 mm, H=35.8 mm, W=5; D=38.2 mm, H=33.9 mm, W=5; D=36.8 mm, H=34.2 mm, mm, W=5).

"var. c." NHMUK 20110282 from Catbalonga and Basay, Samar Island [Philippines] (3 shells; D=43.5 mm, H=34.8 mm, W=5; D=43.8 mm, H=34.6 mm, W=5; D=44.5 mm, H=34.9 mm, W=5).

"var. d." NHMUK 20110283 from Cagayan, Misamis Province, Mindanao Island, Luzon [Philippines] (3 shells; D=35.6 mm, H=28.4 mm, W=5; D=33.1 mm, H=26.1 mm, W=5; D=32.7 mm, H=25.4 mm, mm, W=5).
