The animal of this genus appears to be ovo-viviparous, 

 the same as the Cymbium of Klein, the young ones 

 being arranged in the oviduct of the female in a long 

 string, without egg-shells. The shells are usually orna- 

 mented with a variety of colours, and their whorls, pos- 

 teriorly, are adorned with a diadem of spines; they are 

 usually covered with a smooth, greenish-brown epidermis, 

 and the nucleus is spiral and persistent. New Holland 

 and the great islands of the Eastern Archipelago appear 

 to be the countries in which the species of this genus 

 are found, none of them having been observed in the 

 New World.
