 Shell from four to six inches long, and the breadth at the 

 shoulder of the body-whirl is nearly two thirds of the length, 

 but the Variety is proportionably narrower ; it has eight 

 transversely angulated whirls, and a row on each of obtuse 

 nodulous longitudinal plaits ; the aperture is striated trans- 

 versely, and the pillar has three oblique plaits ; the colour 

 is brown, brownish-white, or yellowish-brown marked trans- 

 versely with blackish lines in pairs. A specimen of a most 

 extraordinary size, eighteen inches long, is mentioned in the 

 Portland Catalogue, p. 189, lot 4015.
