hell description

The shell is taller and narrower than "Duplicaria tristis", and has much more rapidly increasing whorls, with the axial sculpture subobsolete, but fine spiral striae are still present.

The shell coloration varies from uniformly dark shining reddish-brown to almost white, with only the early whorls and lower half of the base reddish-brown. Other variants are dark brown, relieved by a spiral narrow pale zone that may be either sub or supra-sutural.

The shell height is up to 22 mm, and the maximum width is 6 mm.
