Remarks.

We found one specimen from the Cuming collection (NHMUK 1878.1.28.422). Its label specifies that it comes from the collection of H. Adams. This specimen has slightly fewer whorls (11) than stated in the original description (12-14), but has the fourth to sixth spiral cords (clearly visible on the base) completely smooth, while the original figure (Adams and Reeve 1850: pl. 11, fig. 33b) clearly shows that cord four and five bear well-defined granules. Therefore, we doubt that this specimen belongs to the type series and suggest that T. granulatus should be considered a nomen dubium.
