Possible synapomorphy of the group are globineurons (small cells) in the procerebrum.
Eyes positioned on the tips of the tentacles were considered a synapomorphy of a clade named Geophila (Stylommatophora + Systellommatophora), but a recent phylogenomic study found strong support for a clade uniting Ellobioidea (eyes at the base of tentacles) and Systelommatopohra (eyes on the tentacle tips). Stalked eyes thus likely evolved twice independently.
