Prostomium rounded, bilobed, with two eyes. Long, stout, cylindrical palps. On the first setigerous segment a dorsal and a ventral bundle on slender capillary setae. Up to the 6th setigerous segment, only capillary setae, with the exception of the 4th bearing the following modified setae: (1) a row of 3-6 large asymmetrical bristles with a denticulate or wrinkled crest and a blunt hook; (2) an inferior row of 3-6 smaller setae slightly enlarged at the tip, which is spoon-shaped, with a more or less blunt lateral process; (3) a few ventral ,slender capillary setae.
about the 6th-7th setigerous segment appear the ventral hooks with a double curvature and a hooked tip with a very long and slender tooth running nearly parallel to the vertex which is provided with a broad hood. Gills, according to Augener, are only to be found on the 6th setigerous segment in a few specimens; they are simple filaments. 3-4 achaetous posterior segments. A conical pygidium, faintly notched, without cup or funnel. Anus terminal. "Proliferation takes place by the formation of the head of a daughter worm and a new tail for the parent between the ninth and tenth segments."
