Toledonia Dall, 1902

The genus Toledonia was created by Dall (1902) for the species T. perplexa . It is characterised by a small, thin shell that is smooth or can have spiral furrows. The spire is elevated resembling an Acteon . The foot is not forked and the prostate is not divided. Usually there is a diverticulum present between the buccal mass and gizzard and the denticulated rachidian tooth can be flanked by up to two lateral plate-like teeth ( Dall 1902; Marcus 1976; Golding 2010).
