OF 



AURICULIDiE, 



The Auriculidce are a family of Mollusca, which breathe the 

 external air by lung-like organs, and have no operculum. They 

 are distinguished from the other families of Pulmonata by the 

 following characters : — 



The animal is hermaphrodite ; its head terminates in an ob- 

 tuse, somewhat fringed snout ; tentacles two, rather cylindrical, 

 which cannot be retracted like those of Helicidce ; eyes situated 

 near the inner base of the tentacles; mantle thin, with the 

 margin thickened; foot elongate, bearing on its middle the 

 spiral part of the body. 



Shell spiral, variously shaped ; pillar generally plaited in all 

 ages ; body of the penultimate whorl usually toothed or plaited; 

 peritreme sharp and straight, or expanded, thickened, often 

 toothed or transversely ribbed.
