GENUS BUCCINUM. JJ 



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. Dictioji. page 13, tab. ,26, fig. 94), which has 

 been found in the bay of Dublin, upon'tne coasts of England, 

 and upon those of Ireland.
