DESCRIPTION. 159 



Inhabits the American, Indian, and Mediterra- 

 nean seas. 



The Linnaean species Erinaceus and Fihex are so 

 obviously the same, and pass so imperceptibly from 

 the plaited and crowned to the even surface, that 

 the characters of both have been here united under 

 the title Vibex as most appropriate. The figured 

 specimen is an exact link between them, the upper 

 whorls and great part of the inferior one being 

 perfectly smooth, the plaits and papilla extending 

 but a very little distance from the outer lip. In 

 plate XXIV the young shell is given, which by its 

 marking is an Erinaceus ; by its form, a Vihex. 

 The peculiar black spot at the extremity of the 

 Cauda is a sufficient proof of their identity.
