Proboscis with its proximal part finely rugose, distal part smooth, both parts separated by a distinct furrow. Terminal ring without distinct papillae but with two large lateral papillae on the inside of the ring. Tentacular cirri reaching about segment 4-5, ventral pair stouter than dorsal. Segment 2 with parapodial lobes carrying about 10 chaetae and pointed, ventral cirri. Dorsal cirri of median segments rounded, situated on prominent cirrophores. Parapodial lobes with a large number of chaetae. Terminal end of chaetal shaft symmetrical with one large tooth and a few smaller ones on each side. Blades long and slender. Ventral cirri sub-triangular with distinctly pointed tips, longer than the parapodial lobes (E. suecica-detail). Pygidial cirri about as long as broad.
