Description
Prostomium broader than long, not notched between the tentacles. Four rather large eyes, with a lens, arranged in a widely opened trapezium. Tentacles about the length of the palpophores. Palps stout, ovoid. Tentacular cirri rather short, the longer reaching backwards to the 6th setigerous segment. Peristomium hardly longer than the succeeding segment. Jaws very pale yellow, transparent, with 5-6 teeth, the inferior ones blunt. Paragnaths missing on the oral ring. On the maxillary ring they are sharply conical, transparent, little conspicuous. On the first 5-6 setigerous segments, the dorsal cirrus is more or less of the same length as the dorsal ligule. The dorsal and ventral rami are divided each into two elongated conical ligules whose tip is already slightly filiform in the upper dorsal one. The ventral cirrus is shorter. In the succeeding feet, the dorsal ligules become flagelliform (whip-like) and much longer than the cirrus. In the ventral ramus, the setigerous lobe is much elongated and divided at the tip into two filiform appendages corresponding to the two fillets. The ventral ligule is whip-like and nearly as long as the dorsal ligules and the ventral cirrus is much shorter. Behind the 20th foot, the ligule still increases in length, especially the ventral one and are more or less coiled. The dorsal bristles are slender homogomph spiningers. The upper ventral bristles are long and slender homogomph spinigers and heterogomph falcigers; the lower ventral ones are hemigomph, or faintly heterogomph, spinigers and long heterogomph falcigers.
