Description

The length of the shell attains 15 mm, its diameter 6.5 mm.

Very elongated variety, finely ribbed, also found on sponges^[2]

(Description as Nassa ferussaci arcuata) The shell is bulging and strongly ribbed. On the first whorls, the ribs are arched; on the body whorl, they are flexuous. The ribs and the intervals are furrowed by decurrent striae which create a reticulation less pronounced than that of Tritia reticulata, to which this species bears a resemblance. The aperture is weakly compressed on the side of the outer lip; the mode of coloration is similar to that of Nassa subdiaphana. ^[3]

Distribution

This species occurs in the Mediterranean Sea off Tunisia.
