Cyclophorus ibyatensis (Pfeiffer, 1854)

Cyclostoma (Cyclophorus) ibyatense Pfeiffer, 1854b [1852]: 62. Pfeiffer 1854a: 349, pl. 45, figs 19, 20.

Cyclophorus ibyatensis - Reeve 1861: sp. 48. Kobelt 1902: 139.

Type locality.

Insula Ibyat "Bashee group" [Itbayat Island, Batanes Islands, Philippines].

Type material.

Lectotype (design. n.), NHMUK 20130081/1 ( Fig. 11A; D =23.0 mm, H=17.7 mm, W=5), paralectotype NHMUK 20130081/2 (1 shell; Fig. 11B; D =22.0 mm, H=17.9 mm, W=5).

Remarks.

This species was described from specimens in the Cuming collection and only one set of shell measurements was given in the original description. Pfeiffer (1854a: 349, pl. 45, figs 19, 20) republished the description and figured a shell from Cuming’s collection. There are two shells in the NHM collections with an original label in Pfeiffer’s handwriting giving the species name and original collection locality. The specimen which matches the illustration in Pfeiffer (1854a) and the dimensions given in the original description is here designated as the lectotype.
