Hab. Philippine Islands ; Cuniiiig. 



This species, it will be seen, is quite distinct from S. 

 auraHtius, the spines being more delicately attenuated and 

 much more numerous, while the shell is chai-acterized in 

 the young state by a multitude of fine prickles, interspersed 

 at the base with brown-black s])ots.

of similar sculpture. It is of a rich purple rose-colour,
