Gastropoda - Architectibranchia - Cylindrobullinidae
If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|J. Gründel and A. Nützel 2012||The shell is cylindrical with planispiral or slightly concave spire. The whorls embrace at the adapical edge of the preceding whorls so that the last whorl covers all preceding whorls in lateral view. The previous whorls are visible in apical view only. The aperture is high and narrow and lacks folds. The other characters are close to those of Cylindrobullina.|
