Shell thin and fragile, subpellucid, ovate-elongate. Spire 

 conoid, the apex obtuse. Whorls 6, a little convex, separated 

 by an impressed suture, the first very delicately punctate, 

 the rest decussated with strong oblique growth-plica? cut by 

 transverse stria?. Transverse striae close below the suture, 

 more remote towards the lower part of the whorls, and evan- 

 escent below the periphery of the last whorl, which is espec-

 thirds the total length. Columella a little arcuate, truncate 

 below. Lip simple, arcuate and acute. 



Color yellow, lightning-streaked with brown longitudinal

 aperture is milk-white towards the margin within, but in the 

 throat is subpellucid, showing the external markings through.
