130 HELICIDiE. 



ACHATINA. Lamarck. 



Shell spiral, ovate or elongated, turreted, invested with 

 an epidermis, which is frequently (in exotic species) co- 

 loured, but not polished and shining. Mouth ovate or 

 elongated, canaliculated below in consequence of the trun- 

 cation of the pillar-lip ; peristome simple, never reflected. 



Animal closely resembling that of the Bulimus. 



Some of the largest of known land-shells belong to this 

 extensive, though somewhat artificially composed, genus. 

 They are mostly tropical, and often as remarkable for 

 beauty of colouring as for size. In Britain we possess only 

 a single, and that diminutive representative.
