Cyclophorus excellens (Pfeiffer, 1855)

Cyclostoma (Cyclophorus) excellens Pfeiffer, 1855a [1854]: 126, 127.

Cyclophorus excellens - Pfeiffer 1854e: 11, pl. 4, figs 1, 2. Kobelt 1902: 128. Kobelt 1908: 670.

Type locality.

Unknown.

Type material.

Lectotype (design. n.), NHMUK 20130084/1 ( Fig. 7C; D =52.5 mm, H=35.9 mm, W=5), paralectotype NHMUK 20130084/2 (1 shell; Fig. 7D; D =44.0 mm, H=31.3 mm, W=5).

Remarks.

This species was described based on material from the Cuming collection, and only one set of shell measurement was given. Later, Pfeiffer (1854e: pl. 4, figs 1, 2) re-published the description and figured a shell from the Cuming collection. Two shells from Cuming’s collection with an original label in Pfeiffer’s handwriting giving the species name are in the NHM collections. The specimen which most closely matches the measurements given in the original description and the illustration in Pfeiffer (1854e) is here designated as the lectotype.
