Martini was the first conchological writer who separated this species from the Strombus Gallus of Linnæus; under which name are included three shells, so remarkably different from each other, that they hardly possess a single character in common.
The original name of Linnæus I have retained to that species figured by Seba, tab. 62. fig. 1 and 2, and by myself in Exotic Conchology, Part 4.
