or has an umbilical suture; and the genitalia are extremely lengthened. Jaw either plaited or solid.
Odontostomini is clearly a natural group of genera, confined to South America east of the Andes, and with the exception of some species, south of the Amazon. That the whole series had its inception in a form in which the characteristic apertural teeth had already been developed, is demonstrated by
the fact that these lamella and folds are clearly homologous throughout the species of the several genera. It follows from this that the toothless forms, such as Moricandia
, are secondarily so, by degeneration of the teeth of their ancestors. Many species show the various stages of tooth
degeneration.
Land snail
A land snail is any of the many species of snail that live on land, as opposed to those that live in salt water and fresh water. Land snails are terrestrial gastropod mollusks that have shells, It is not always an easy matter to say which species are terrestrial, because some are more or less...

Odontostomini
Species in tribe Odontostomini have the aperture obstructed by internal lamellae, folds or teeth (rarely absent by degeneration); the base is perforateor has an umbilical suture; and the genitalia are extremely lengthened. Jaw either plaited or solid.
Odontostomini is clearly a natural group of genera, confined to South America east of the Andes, and with the exception of some species, south of the Amazon. That the whole series had its inception in a form in which the characteristic apertural teeth had already been developed, is demonstrated by
the fact that these lamella and folds are clearly homologous throughout the species of the several genera. It follows from this that the toothless forms, such as Moricandia
