502 CYPR^AD^. 



MARGINELLA. Lamarck. 



Shell ovate or oblong, smooth ami polished, spire sliort 

 but visible, body-whorl large, more or less veutricose or 

 sub-cylindrical ; aperture narrow, canaliculated below ; 

 outer lip more or less inflected, often thickened and den- 

 ticulated. No operculum. 



Animal with large, usually papillose mantle-lobes, re- 

 flected on the shell and over the spire ; head somewhat 

 muzzle-shaped, mouth with a retractile proboscis ; tongue 

 constructed like that of Cypraa, tentacles subulate, bearing 

 eyes on bulgings at their external bases ; siphon produced ; 

 foot large, truncate in front, obtuse behind. 



The only British species of this elegant genus belongs to 

 that section of it in which the shells have a thickened 

 outer lip. These constitute the genus Erato of Risso, but 

 cannot be regarded as more than a section of Marginella.
