Remarks.

The two specimens preserved in the NHMUK (196515 and 196516) and belonging to the Cuming collection cannot be considered syntypes. The original description, as well as the original figure (Fig. 10G), describe a specimen with an incomplete aperture, in contrast to the specimen illustrated in Figure 10A-C. Moreover, the original description refers to a shell with 20 whorls, while both specimens found have 9-12 teleoconch whorls; specimen in Figure 10D has also a large paucispiral protoconch in contrast to the elongated and pointed profile of the original figure which suggests a multispiral protoconch. At present, T. alveolatus should be considered a nomen dubium.
