Tbe colour of this highly sculptured, torn ate, and spirally noduled 

 species is remarkable, being an ashy brovsn, developing at the base, 

 and over the greater part of the body-whorl, to deep plum-coloured 

 purple. The noduled ribs in the centre of all excepting the apical 

 and body whorls give an angular appearance ; these disappear for 

 the greater part on the last whorl, the beautiful cancellations 

 being here seen with the best effect.
