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.

K. Bandel 2006The protoconch of Paracerithium COSSMANN, 1902 has three spiral lines on the larval shell. The subsutural row of dots and the spiral ribs on the larval shell resembles that of Argyropeza but the protoconch may be larger. The subfamily is based on the genus Paracerithium from the Jurassic. The teleoconch is characterized by an aperture with anterior notch, conical shell shape and ornament with one or two strong spiral ribs creating a keeled appearance. Smaller spiral lines cover the whorl flanks as well as the base. The few widely spaced axial ribs continue from the suture to the spiral keels on the median whorl, forming nodules with them where they cross.
