In this genus the last whorl is usually spinose or tuber- 

 cled, and the outer lip is thin and acute : the species are 

 tolerably numerous, and are principally inhabitants of the 

 East Indian Islands. As the shells increase in size the 

 animals fdl the nuclei of the spire with solid calcareous 

 matter.
