Enoidea

Chondrula tridens, photographed by Jozef Grego.

Belongs within: Stylommatophora.

The Enoidea is a group of medium-sized snails most diverse in the Palaearctic and Africa.

Characters (from Tillier 1989, as Enidae): Visceral mass obviously shortened. Cerebral commissure and lateral connectives never very long. Left cerebro-pedal connective always longer than right. Left parietal ganglion always touches both left pleural and visceral ganglia.
