*) Shell much elongated ; pale brown, often at the summit deep reddish 
brown , with several spiral series of very small deep brown spots , of which 
those next below the suture are the larger , and a somewhat interrupted 
band of the same around the anterior extremity; with closely set much 
elevated sharp transverse lamellae, which are slightly crenulated by numerous 
spiral impressed lines , of which one next below the suture is more deeply 
impressed ; spire with scarcely convex outlines ; apex truncate with the loss 
of nearly three Avhorls ; nearly five quite convex whorls remaining , with a 
well impressed suture; last whorl a little detached from the penult whorl 
next the aperture; aperture ovate- orbicular ; lip simple, slightly spread, re- 
flected nearly into the plane of the aperture , more developed at the angle
