This shell is very different from other species in its form, 

 which is globular, and its color, of a deep violet. In some spe- 

 cimens the spire is more elongated, and sometimes, within the 

 shell, where it is of a paler violet, are delineated deeper bands ; 

 one only exists upon the upper whirls, and two broader upon 

 the lowest. 



This species strongly resembles in its form the BUCCINUM 

 ovum of Turton, figured in the Zoological Journal, vol. II. 

 pi. 13, fig. 19 ; but it is thicker and more colored than that, 

 which, on the contrary, is thin and of an ivory white.

Shell ovate, conical, of a bluish ash color, traversed by dis- 

 tant lines, articulated and generally formed by oblong black 

 points ; the spots upon the upper whirls are larger, flamed, 

 more or less numerous. Seven whirls to the spire ; they are 

 slightly convex, and united by a pretty fine and regular linear 

 suture. The aperture is oblong ovate, slightly longitudinal, 

 smooth and of a chamois-yellow color ; the right lip is thin 

 and sharp. 



Length 2 inches. Width 1 inch. 

 Inhabits the seas of New Zealand. 



We have figured several specimens of the shell at different 

 ages and of different varieties, to show how much this species
