Description
The length of the shell attains 15 mm, its diameter 6 mm.
The dark sienna-brown shell is elegantly fusiform.It contains 8 whorls 8 (the protoconch is imperfect in our specimens). The remainder are very closely and finely longitudinally costate, say about sixteen on the body whorl, slightly oblique, warm-brown in colour, with a spiral white band just below the sutures. The ribs are particularly nurmerous and fine in character, not in the least incrassate. The surface is crossed with uniform spiral raised lines. These extend very nearly to the base of the body whorl. The aperure is narrow. The outer lip is rather incrassate. The anal sinus is well expressed, just below the suture. The columellar margin is straight. The siphonal canal is very short.

This marine species occurs off Cuba , in the Gulf of Mexico and off the Lesser Antilles.
