Remarks.

The reproductive anatomy of Orcula schmidtii transversalis ( Westerlund 1894) was described by Hausdorf (1987) and Reischütz and Sattmann (1990). According to Hausdorf (1987), the penial caecum of Orcula schmidtii transversalis is short, but simple. The caecum appears double in the illustration provided by Reischütz and Sattmann (1990).
