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 Zodlogical Journal, vol. II. 
pl. 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
