Remarks.

Martens (1873) and Strebel (1909) both based themselves on material in the ZMB. Strebel mentioned "Das Stück stammt aus den Albersschen Sammlung und ist von Grüner in Maracaibo gefunden", thus he implicitly described this taxon from one shell. The specimen found corresponds to the figures given by Strebel, and is regarded the holotype. There is also a label indicating that Albers had two specimens ( “37-38”), but only one specimen is present and was mentioned by Strebel (1909). The current systematic position is following Richardson (1993).

Current systematic position.

Orthalicidae , Orthalicus gruneri (Strebel, 1909).
