DESCRIPTION. Shell turreted, elongately bi-conical, spire shorter than 

 body-whorl ; volutions 9 or 10 divided by a linear suture, posteriorly wide 

 and depresso-concave, narrow and nearly vertical in front, last whorl furnished 

 with a straight canal which is slightly twisted at the base, apex consisting of 

 two or three smooth inflated whorls (protoconch not preserved) ; labrum 

 smooth interiorly, wide and angulate at periphery, provided in rear with a 

 deeply ovate central sinus ; columella nearly straight, covered with a thin 

 callus exposing the spiral ornamentation. Sculpture composed of close, 

 deeply ovate, longitudinally sinuous lines contained within the periphery and 

 the suture where they are thickest and there forming a necklet of short 

 equi-distant oblique costae, all being crossed by regular and well marked 

 spiral lines ; the periphery bears a circlet of small, equi-distant, bead-like 

 tubercles succeeded below on the penultimate whorl by two or three similar 

 rows of tubercles arranged beneath each other and which are fewer on the 



O 



earlier stages of the spire ; the tubercled periphery of the body -whorl is followed 

 in front by numerous circlets of nearly contiguous tubercles, each circlet being 

 separated by a row of smaller tubercles, while the whole of this spiral ornament 

 is crossed by strong, outwardly curved and crowded lineations which proceed 

 from the sinuations in rear of the periphery, and which are continued 

 perpendicularly over the surface of the canal.
