Shell nearly covered perforate, trochiform, thin, shining, nearly 

 smooth (under a lens seen to be decussated with incremental and 

 transverse striae,) pellucid white under a very thin buff epidermis. 

 Spire elevated, conoid, the apex obtuse ; suture simple. Whorls 7, 

 nearly flat, the last convex beneath, carinated at the periphery, a 

 little descending and subconstricted in front. Aperture oblique, 

 subquadrangular, angulated at the termination of the carina ; peris-
