The prostomium bears a pair of long antero-lateral antennae
and a pair of long tapering ventral palps. Nuchal organs are
present. A short muscular eversible barrel-shaped pharynx is
present; the surface of the everted pharynx is covered with
scattered oblong papillae and terminal papillae. Jaws are
absent. The first segment is indistinct, and bears two pairs of
long tentacular cirri. The neuropodial lobes of the parapodia
are elongate. Notopodia are represented only by
a digitiform dorsal cirri (present from chaetiger 2).
Neurochaetae are compound. Aciculae and one
pair of very long pygidial cirri are present.
