AZECA. 



To those not well acquainted with conchology this 

 species may readily be mistaken for that of Zua; the 

 form of the shell closely resembling Zua. The chief 

 distinction lies in the mouth, which is ovate and pro- 

 vided with teeth, whereas in Zua it is toothless. 



The animal is similar to a Zua. 



Only one species is found in Great Britain.
