 equidistant axial riblets, about twenty on the last whorl, interstices 

 with microscopic fine growth-lines ; points of intersection ornamented 

 with round gemmules. Colour yellowish -white. Spire high conical, 

 much higher than the aperture ; outlines almost straight. Protoconch 

 papillate, of two convex smooth whorls, a little deviated from the 

 vertical axis. Whorls about 7, regularly increasing, flatly convex ; 

 base smooth and slightly concave. Suture impressed, channelled by 

 the cingula. Aperture vertical, ovate, angled above, produced below 

 into a short, widely open, and basally emarginate canal. Outer lip 

 sinuated by the spiral sculpture ; basal lip produced beyond the canal.

Shell small, elongate, thin and fragile, translucent, finely reticulated. 

 Sculpture : the first two whorls smooth, the following four with three 

 subequidistant fine spiral threads, and the body-whorl with five, the 

 two lowest a little stronger than the others ; they are reticulated by 

 subequidistant, slightly oblique, and flexuous axial threads, slightly 

 nearer together than the spiral lines, and extending over the base ; 

 interstices with fine microscopical growth-striae. Colour yellowish- 

 white. Spire high, turriculated, outlines lightly convex. Protoconch 

 of two convex, smooth, and polished whorls. Whorls 7, regularly 

 increasing, convex, flattened towards the suture ; base slightly convex. 

 Suture impressed. Aperture subquadrangular, produced below into 

 a short and open canal. Outer lip rounded, thin, and sharp ; basal lip 

 bent almost straight over towards the canal. Columella vertical, 

 straight, curving off at the base to form the inner margin of the canal.
