What is "brasilennea"

Brasilennea is a fossil genus of small to medium-sized air-breathing land snails, terrestrial pulmonate gastropods in the family Cerionidae. The genus is known only from the Brazilian Paleocene Itaboraí Basin, in Rio de Janeiro. The most characteristic feature of the genus is its two spiral furrows on the body whorl.

The name Brasilennea implies that it is a Brazilian genus that is very similar to the African genus Ennea. The genus was originally classified in the family Streptaxidae, but it was later transferred to the family Cerionidae.
