[3] Duvaucelia lineata was originally discovered in 1846 and described by British malacologists Joshua Alder and Albany Hancock in 1848.

Veil produced into four long filaments; the two nearest the centre longest and tapering gradually to a point, the side ones shorter and obtuse.

Tentacles pale yellow, the fascicules of filaments slender, and the sheaths rather tight.

Branchiae rather slender, bipinnate, transparent, with an opake white line in the centre of each running into those on the back.

[1] Duvaucelia lineata is found at scattered localities on the coasts of Great Britain and Ireland and in southern Norway and Brittany, France.
