19. Turbo serrrcostatus. Hal/cribbed Turban. 

 Montagu, pi. 21. f. 5. 



Shell conic, short, obtuse, white, sometimes transpa- 

 rent : spires fair or five, rounded and well defined by the 

 separating lin* ; the larger ones marked with faint longi- 

 tudinal ribs, m>t extending the whole length of the volu- 

 tion, and strate transversely where these ribs terminate, 

 so that the volutions are partly ribbed lengthways, and 

 partly striate across ; but both marks are lost on the smaller 

 volutions : aperture somewhat orbicular ; pillar smooth, 

 slickly reflected at the lip : length half a line j breadth 

 half its length, 



t sometimes resembles the Turbo spiralis ; but the VOT 

 lutjons are more rounded, the ribs are coarser, and it wants
