Type material.
Lectotype (design. n.) NHMUK 1888.12.4.1967 (Fig. 7B).
Remarks.
The species description was very brief and only one set of measurements was given. The NHM collections contain a mixed-species lot consisting of two specimens with an original label stating “Type”. The specimen that matches with the figures in Hanley and Theobald (1870: pl. 5, figs 6, 7), the measurements (width 29.6 mm) given in the original description and marked with an “x” is here designated as the lectotype to stabilise the name.
The other shell, NHMUK 1888.12.4.1977, differs from the lectotype in having a smaller shell width (23.6 mm), shallow suture without a canal-like structure and an expanded apertural lip without a canal-like accessory respiratory structure. We considered this shell as a distinct species, and so it excludes it from the type series.
