The case is relatively slim and tall, it has 12 to 13 turns. It measures in height to about 2.5 cm in diameter max. 5 mm. The last four turns take very little to the width, the flanks thus almost parallel to each other. The windings are externally flattened, nearly straight; thus are only slightly deepened the seams.

System

Emil Adolf Rossmaessler cited as the author of nature " Ziegl. ", But the description of nature is (probably incorrectly) attributed exclusively Rossmaessler. It was later determined the type species of the established by Boettger in 1877 Montenegrina genus. The genus Montenegrina currently contains more than 20 species that are native to the Balkans to Greece.
