Shell elongate, turreted, rather slowly increasing, whorls seven, almost conical, 

 slightly ventricose and with shallow suture. Slit band 3 millims. wide, situated above 

 the middle of the body whorl and on the other whorls near the upper suture, at a 

 level with the surface of the shell, the crescents small and narrow, very dense. The 

 ornamental lines are transversal, uniform, dense, turned in a highly acute angle towards 

 the slit band. The aperture is ovate, higher than broad. The umbilicus is very nar- 

 row and nearly hidden by a reflexion of the columellar lip.
