Description The length of the shell varies between 35 mm and 50 mm.
The ponderous shell is dark chestnut or chocolate. The shell shows a slight shoulder-angle, above which the whorls are slightly concave to a sutural band. Below the shoulder the shell shows close rude longitudinal ribs, sometimes decussated into nodules by the raised revolving lines. Towards the base of the body whorl the latter remain prominent, whilst the former have vanished.G.W.
