Two specimens of tbis very pretty species were collected by 

 P. W. Bassett-Smitb, Esq., of H.M.S. "Penguin." The upper 

 surface bears considerable resemblance to our common British Gihhula 

 magus, Linn. The keel of the body- whorl, and one of the lirse around 

 the middle of the base, are very prettily spotted with deep rose and 

 white.
