The body-whorl of the older specimens of this shell is rather roughly striated or wrinkled, the last but one slightly so, and the remaining whorls are quite smooth. The colour is whitish, with
purple spots more or less obsolete: the old specimens are sometimes of a dull yellowish white. A specimen is deposited in the British Museum.
The young shells of this species are of a whitish brown, with darker coloured striæ. They are very fragile and semi-transparent.
