or reddish color, oblong or quadrangular, alternating with 

 other similar spots of a dull white : the first, oftentimes, form 

 longitudinal bands ; spire conical, pointed, formed of six slightly 

 convex whirls, the lowest of which is as large as all the others ; 

 they are flattened and angular at the upper part, crowned upon 

 the angle by a subgranulated margin ; the suture is accom- 

 panied at the upper part of each whirl, by a small, slightly 

 convex and undulating margin ; upon the lower whirl are seen 

 nine rounded, transverse, very angular folds : the other whirls 

 are also ornamented with three folds. The spaces between 

 them bear fine transverse striae. The aperture is white, ovate, 

 elongated ; columella thick, rounded, white and almost straight. 

 The right edge is thin, and slightly sharp.
