*) 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

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 l. c.)
