MUEICID^. 



The aperture is nearly twice as long as the spire, and the revolv-

Shell turreted, rough, inelegant, antiquated, dingy white, or faint 



brownish horn color ; whorls 

 eight, very convex, rather ven- 

 tricose, encircled by distant, 

 elevated, light chestnut col- 

 ored bands or ribs ; on the up- 

 per whorls two of these lines, 

 more prominent than the rest, 

 give them a bicarinated appear-

 are usually three lines, and on 

 the lowest are several others, 

 gradually diminishing in prom- 

 inence, and never reaching 

 the front, except in immature 

 shells ; sutural division abrupt ; 

 strice of growth quite apparent, 

 1)ut, Avith these exceptions, the 

 shell has a smooth and worn 

 ai)i)earance ; aperture rather 

 less than half the length of the 

 shell, broad oval, and some- 

 what dilated ; outer lip sharp 

 and somewhat angulated by 

 the most prominent revolving 

 bands ; inner margin covered 

 with a callus in mature shells ; canal short, and very much re-
