Description
The shells of ''Fustiaria'' are characterized as smooth, slender, circular in cross section, slightly curved, thin-walled, and virtually transparent. The central tooth of its
radula
The radula (, ; plural radulae or radulas) is an anatomical structure used by molluscs for feeding, sometimes compared to a tongue. It is a minutely toothed, chitinous ribbon, which is typically used for scraping or cutting food before the food ...
(chewing organ), called a "rachis", is unusual compared with that of other Dentaliids in that it is flat on its tip rather than pointed. The space around the foot (the "pedal sinus") is divided by a thin horizontal membrane called a
