vex slope; the upper whirls are crowned upon the slope with 
a small row of tubercles; between each suture of the whirls of 
the spire, exists a deposit of white and smoother matter, which 
is seen at the upper part, and which terminates by a sort of 
callosity upon the side of the columella ; aperture reddish, wide 
and ovate, terminated by a pretty large emargination ; lip 
simple and arched. 
Length 2 inches. Width 1 inch 6 lines. 
Inhabits the islands of the South Sea, and especially the 
coasts of New Zealand. 
This handsome species is particularly remarkable by the tur- 
reted whirls, and above all by an original deposit of whiter cal- 
careous matter, which is seen at the upper part of the lower 
whirls of the shell. 
The young specimens of this species appear to approximate 
in their form and diminutiveness, the Buccinum carinatum of 
Turton (Conch. Diction. page 13, tab. 26, fig. 94), which has 
been found in the bay-of Dublin, upon the coasts of England, 
and upon those of Ireland.
