generic character. 



Animal a Limax. Linn* Shell univalve, spiral, gibbous, 

 flattish at the bottom ; aperture semi-orbicular and semi-lunar, pillar 

 lip transversely truncated. 



# # # Perforated with the lips denticulated. 



* Linnaeus describes the animal of the Nerita as a limax, the body of 

 which is oblong, with a fleshy shield above, and a longitudinal flat disk 

 beneath : aperture on the right side within the shield ; feelers, four, placed 

 above the mouth : eyes, two, and situated one at the tip of each of the 

 larger feelers. This character does not exactly accord with the animal of 

 the Nerita, for in this tribe, instead of the eyes being situated upon the apex 

 of the longer feelers, they stand each upon a kind of papilla, situated at the 

 outer base of the longer feelers. And besides this, it differs in some less 

 material peculiarities.
