Popis
Mitra antillensis: The Caribbean analogue of the west American Mitra swainsonii differs from this species only in features of sculpture. The spiral grooves are distinct and deeper, and produce 9 flat spiral cords on the penultimate and 24 cords on the body whorl in the holotype; the columella has
5 folds and a very small sixth fold anteriorly. The longitudinal sculpture is also more prominent, particularly around the sutural area. The Caribbean species appears to live in appreciably deeper depth than the nominate subspecies.
Holotype of antillensis: Height 81.0 mm; Width 23.0 mm; Height of aperture 40.0 mm.
