Fustiaria

Fustiaria is a genus of scaphopods in the order Dentaliida and is the only genus comprising the family Fustiariidae, with 24 species.

==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 (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 septum.
