Bothriembryon tasmanicus, photographed by Ken Harris.

Belongs within: Orthalicoidea.

The Bulimulidae is a group of land snails including the Australasian Bothriembryon and a number of Neotropical taxa. Within the Bulimulidae, the Odontostomini are distinguished from other taxa by the presence of only a small number of mandibular plates, and of dents and/or lamellae narrowing the lamellae (Breure 1979).

Characters (from Breure 1979): Mandibula with large number of plates, smooth surface and amorphous internal structure; radula with central teeth mono- or tricuspid, and transverse tooth rows straight or V-shaped; genitalia with genital atrium absent, penis cylindrical, penis appendix absent, proximal penis sheath present or absent, flagellum present, retractor muscle slender and thin, spermoviduct not torted, spermathecal duct as long as spermoviduct or reduced; pallial organs with sigmurethrous ureters, weak to strong pulmonary veins, adrectal ureter open or closed; columellar muscle present; protoconch sculptured.
