Shell elegantly fusiform, dark sienna-brown, whorls 8, nuclear ? imperfect in our specimens, the remainder very closely and finely longitudinally costate, say about sixteen on the body-whorl, slightly oblique, warm-brown in colour, with spiral white band just below the sutures. The surface is crossed with uniform spiral raised lines; these extend very nearly to the base of the body-whorl. Mouth narrow, outer lip rather incrassate, sinus well expressed, just below the suture, columellar margin straight, canal very short. Long. 15, lat. 6 mm. Hab.—Cuba.
A striking little shell both in form and coloration. The ribs are particularly numerous and fine in character, not in the least incrassate. Indeed, it superficially recalls some small Mitra of the subgenus Turricula.
