Auriculella

(Original description in Latin) The shell is subperforate and possesses an oblong-conic shape. The apertural wall is armed with a spirally entering lamella, while the columellar fold is situated superiorly, appearing either tooth-like in form or, in some specimens, nearly obsolete. Finally, the peristome is slightly expanded. ==Distribution==

They are endemic to Hawaii (United States) and several are extinct. They are oviparous (egg laying) and hermaphroditic. Among achatinellid snails, they are unique in the fact that they are not restricted to living on plants endemic to the Hawaiian islands. They have been known to relatively thrive on non-native plants such as ginger and night jasmine. ==Species==
