Lectotype (design. n.), NHMUK 20130113/1 ( Fig. 3A; D =30.0 mm, H=23.5 mm, W= 41/2 ), paralectotype NHMUK 20130113/2 (1 shell; Fig. 3B; D =26.0 mm, H=22.5 mm, W= 41/2 ). Remarks . This species was described based on specimens from the Cuming collection. In the original description only one set of specimen measurements was given. In 1854, Pfeiffer (1854a : 346, pl. 45, figs 11, 12) re-published the description and illustrated a single specimen from the Cuming collection. There are two specimens from the Cuming collection with an original label in Pfeiffer's handwriting stating the species name, and a subsequent label stating "Type" . The figured specimen in Pfeiffer (1854a) can be recognized by the varix on the last whorl, and is designated here as the lectotype.
