Judging from the worn shell in the collection of Mr. Bell, the 

 species must have been beautiful, the colour being pale lilac, 

 with a broad band of darker tint, and the outer lip a delicate rose. 

 Tins skell differs from M. L'argillieri in kaving four folds on the 

 columella, and in the different form of the columellar swelling at 

 the posterior end.
