Description

The length of the shell attains 100.2 mm.

(Described as Buccinofusus berniciensis) The whorls are encircled with alternately larger and smaller revolving ridges, decussated by fine growth-lines. The margin of the outer lip is slightly everted. The shell is thin, white and covered with a very thin, light olive epidermis.^[2]

The shape of the shell is variable in height and in height-to-breadth ratios, depending on the depth of occurrence and the latitude.^[3]

Distribution

This species occurs in the northeastern Atlantic Ocean in deep water between 400 and 1600 m from the Morocco coast to Norway.
