phores and small papillar palpostyles, paired short lateral antennae, 

 ^vithout median antenna. Tentacular segment with 2 pairs of ten- 

 tacular cirri. Parapodia subbiramous. Notopodia with inflated 

 cirrophores with internal notoacicida, without notosetae; conical dorsal 

 cirri more or less set oft' from dorsal cirrophores. Neuropodia conical 

 lobes with stout nem-oacicula; neurosetae simple, variable in length; 

 ventral cii-ri short, conical. Pygidium with or without short anal 

 cirri. Proboscis unarmed, globular. Integument minutely papillated.
