« Shell taper, brown, whorls transversely striated, and longitudinally undulated. Aperture toothless. » – E. Donovan: The natural history of British shells… vol. V, London 1803 (1804), plate CLXXIX fig. II. However, we notice some labial denticles inside the aperture. We can also notice the minute longitudinal striae, notably marked in the interspaces between the transverse cords, and obsolete on the latter.

Whatever the colours of the shell, the spiral banding is continuous, while it is interrupted in mamillata for example, and varies in strength in turritellata. Notice also the longitudinal folds, which are not mandatorily aligned from whorl to whorl. Finally, the sculpture is less cancellate than in recondita. – Above: subadult from 8m deep, Bozcaada island, Çanakkale, W. Marmara, NW. Turkey. 5,7mm.
