Description
editThe length of the shell attains 2 mm, its diameter 1 mm.
This is a very small and narrow shell, coniform or subcylindrical. The very short spire consists of subulate whorls, separated by indistinct sutures. The body whorl is very large, olivoid and attenuated in front. The aperture is narrowed in the middle by the contraction of the outer lip which folds up a little inside, although it is not very thick. The columella contains four folds.[2]
Distribution
editFossils of this marine species were found in Eocene strata in Paris Basin, France.
