Two western Atlantic vitrinellids, Cyclostremiscus beauii (Fischer, 1857) and Circulus texanus (Moore, 1965) new combination are redescribed based on a study of live snails from the burrows of the stomatopod crustacean Lysiosquilla scabricauda (Lamarck, 1818). Anatomy and reproductive biologyare emphasized, with the first recorded description of spawn and larval development in the family. Synonymies are given, and a lectotype isselected for Cy. beauii. Literature data concerning anatomy are reviewed for the marine near-planispiral rissoaceans; Vitrinellidae (including Cyclostremiscus and Circulus, with Circulidae as a synonym) is considered distinct from Tornidae. Unusual morphological aspects of Cy. beauii are discussed, including external ciliation patterns, pallial tentacles (which are functionally and morphologically different from each other), and stomach morphology (with a large posterior chamber). Protandroussequentialhermaphroditismin Cy. Beauii is inferred (for the first time in the Rissoacea) from morphological evidence of sex change correlated with size.
