Remarks. — This curiously and elegantly painted shell I owe to Lieu- 

 tenant Dornin, who, when on board the sloop of war Vincennes on 

 her voyage round the world, very kindly collected for me many rare 

 and fine specimens. It is eminently distinguished by its compound 

 band, its globosity, and its innumerable minute spots. The columella 

 is somewhat thickened by a dark pink deposit.
