All specimens attached by their posterior side have the same ovoid shape with the oral siphon apical and the atrial at 1/3 of the body length. The tunic surface has a pavement of lenticular swellings on the body and tubercles on the siphons. Red in life the colour becomes brownish after fixation. No tunic spinules have been found and there are no epibionts. Extracted from the tunic the body wall is not transparent with red siphons and yellowish body. The musculature is dense (
