5. THE CYMATIUM (No. 1) 



A brilliantly colored animal preferring warm waters inhabits these rugged shells 

 The two varices to a whorl is a distinguishing characteristic from the closely 

 related murex with its three varices. 



Remember the triton shell used as a horn in ancient Greek literature? The 

 Australian and Polynesian islanders are still using tritonis, the largest species, for 

 this purpose. In parts of India left-handed spirals are considered sacred.
