Axial sculpture of raised lines which are seen between the spiral keels. There is a narrow, but deep, umbilical chink and a tooth on the columella.

DISTINGUISHING CHARACTERISTICS
The more conspicuous spiral sculpture, together with the evident prosocline growth-lines, make this species easily distinguishable from all the other Mediterranean pyramidellids. Perhaps, shells of this species with damaged apex could induce to a hurried identification with some rissoid species (e.g. Alvania weinkauffi (Weinkauff, 1868).
BIOLOGY / ECOLOGY
On the basis of the living specimens found along the Turkish coasts, it is possible to assume that this is a shallow water species.
habitat :
5-6 m depth.
