Troschelia berniciensis explained

Troschelia berniciensis is a species of sea snail, a marine gastropod mollusk in the family Buccinidae, the true whelks.

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.^[1]

The shape of the shell is variable in height and in height-to-breadth ratios, depending on the depth of occurrence and the latitude.^[2]

Distribution

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