On the anatomy of Novisuccinea strigata (L. Pfeiffer, 1855) (Gastropoda, Stylommatophora, Succineidae) from British Columbia, Canada

Novisuccinea strigata (L. Pfeiffer, 1855) is an arcticboreal terrestrial mollusc that is both amphiberingian and occurring across a large area of northwestern Canada, including northern British Columbia, Yukon, and the Northwest Territories. The shell, jaw, and reproductive anatomy is described from specimens collected near the Hyland River, on the Liard Plain for northern British Columbia. Reproductive anatomy, and most notably the twisting of the free oviduct around the duct of the bursa copulatrix, indicates that this species properly belongs to the genus Novisuccinea as redefined by some American workers.
