“TOLEDONIA, new genus.
Shell small, smooth, thin, imperforate, succineæform; pillar continuous with the basal margin of the aperture, straight, but with an elevated thin plait near the base of the pillar, which appears to he continued into the coil of the shell; nucleus smooth, dextral; soft parts unknown. Type, T. perplexa Dall.
This little shell has a combination of characters which prevent its being assigned to any known genus. It differs from any of the Pyramidellidæ in its form and dextral nucleus; from the Actæonidæ by its peculiar pillar and dextral nucleus; from immature Ringicula by its single plait and general aspect. It is not certain even to what family of gastropods it should be assigned. As it was dredged at a considerable depth there seems no reason to doubt it is normally marine.”
(Dall, 1902: 532-533)
