operculum is corneous and pancispiral. Its nucleus is near the inner lip.
The animal shows subulate tentacles, approaching at the base. The eyes are large and nearly sessile. The foot is truncated in front. The foot of Eulima secretes a mucous filament which assists to sustain it in the water. The mentum is bilobed. The opercular lobe is winged on each side. The branchial plume is single."
