Belongs within: Heterobranchia.

The Architectonicoidea is a group of marine gastropods uniting the Architectonicidae with related fossil families. The Architectonicidae, sundails, have discoidal or depressed-conical shells with a rather flat base, often with a very widely open umbilicus within which the coiled whorls are visible, and a sculpture of beaded spiral and radial ribs (Wilson & Gillett 1971).
