is circular. Additionally, there are specimens with slightly compressed to slightly depressed conch cross section, which are identical to the type in all other features. The relatively low number of specimens in the collection does not allow for a proper evaluation of this character for classification purposes. Here, the variability in conch cross section is interpreted as intraspecific and the species diagnosis is emended accordingly.
