Belongs within: Heterobranchia.

The Architectonicoidea are 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). Fossil relatives include the Middle Triassic Amphitomaria cassiana which has a discoidal shell with a slightly concave outer whorl face bordered by well-defined carinae (Knight et al. 1960).
