 Shell sometimes two inches long, and nearly half as broad, 

 formed by eight whirls gradually tapering to a point ; colour 

 white, or bluish with transverse bands of red, green, yellow, 

 black, or brown, and varying in number. Gmelin after hav- 

 ing cited the same figure for B. Virginea, has afterwards 

 constituted another species with the name of B. ambigua, 

 from Knorr, vi. t. 28. f. 4, which, though badly executed, 

 was certainly intended either for B. Virginea or B.fasciata. 



fasciata. 46. Shell conical, with transverse 

 bands; pillar sub-truncated, and the aper- 

 ture white.
