This species was described in 1908, it was endemic to the Kohala Volcano in the northern part of Hawai’i, Hawaiian Islands.
The shells were very distinct, they were covered with transverse striae that were strongly developed, with cuticular margins which could very easily be broken, they reached sizes of about 0,26 cm in length.
