Remarks: Trunk cylindrical or flask­like, 0.7–14.2 mm long, 0.5–1.7 mm wide. Introvert partly everted 12–14 mm long, 0.2–0.8 mm wide. When fully extended, introvert 7 times trunk length. Skin thin, transparent or thick, opaque, furrowed. Introvert with 22–40 rings of hooks; 28–35 µm high, 15–18 µm thick at base. An accessory comb with 4–6 spinelets at base of hooks. Ventral retractors thicker than dorsal ones. Intestine and rectum long. Nephridia mostly orange in colour; one or bi­loped; second lobe smaller than primer one. Nephridiopores located in front of anus. Intestine spiral with 10–24 coils. Papillae on trunk globular, rosette sometimes dome­like shaped. Large adult specimens bearing mammiform papillae. Papillae on posterior part of trunk 5–28 µm long, 5–48 µm in diameter. Some specimens with eggs, elliptical; longer axis 50–80 µm in diameter, smaller axis 35–55 µm in diameter.

Distribution: Western and eastern Atlantic Ocean, Mediterranean Sea, two sides of Indian Ocean ( Cutler 1994). Depth range: 300–1860 m ( Cutler 1969; Cutler & Cutler 1987).
