Original description: Stichocorida (vel Stichocyrtida eradiata aperta) with cylindrical shell, the upper pole of which is rounded, the lower truncate. Cephalis with a horn.

The genus Artostrobus and the following Dictyomitra
Translated description: Lithomitra] differ from all the other Stichocorida in the cylindrical or nearly cylindrical form of the shell, all the joints of which are nearly equal in breadth, and are very short, often with a single transverse row of pores only. The first joint or cephalis is usually different from the following, often hemispherical or cap-shaped joints. The last joint is truncate, and has a wide-open mouth. Since the constrictions between the single joints are often very slight, some species are very similar to the Dicyrtid Sethocorys.
Remarks on original description: In description for Dictyomitra read Lithomitra.
