This strangely distorted shell is about an inch and three-quar- 

 ters long, and more than an inch broad, and is variously car- 

 buncled all over; the whirls are partially and alternately 

 gibbous, and have irregular decussated ribs, which form no- 

 dules or granules of different- sizes at their intersections ; 

 the aperture is surrounded by a widely expanded thin mem- 

 brane over both its lips, and ends in a short recurved beak ; 

 the colour is white with indistinct bands of pale reddish 

 yellow.

 slightly ascending ; the colour is brownish white, and the 

 membrane which expands round the aperture has a purplish
