*) Shell much elongated, conic: silky white, with four spiral series of 
brown dots , of which three appear on the spire ; around the umbilicus is a 
fifth series less distinct: with crowded regular transverse obtuse fine raised 
lines.: spire with the outlines moderately convex , truncated with the loss of 
two whorls ; whorls remaining four and one-half, quite convex, with a rather 
deep suture : aperture slightly detached from the penult whorl ; inner peri- 
treme indistinct; outer peritreme moderately expanded, except on the left 
side, which is not reflected: umbilicus small. (Adams 1. c.) 
**) Shell elongate conic: color — ? with numerous transverse modera- 
tely elevated lamellae: apex acute: spire not truncated, with the outlines 
but little convex: whorls six and one-half, quite convex, with a rather deep 
suture ; last whorl at the end much detached from the penult whorl , and 
angular above: aperture nearly circular, with the inner peritreme moderately 
produced, and the outer peritreme small and expanded into the plane of 
the aperture; umbilicus small. (Adams 1. c.)
