The eyes are obscure, situated behind the bases of the outer paired tentacles. The gills begin as a slender filament on the first setigerous somite. In one specimen they become 2-branched on the fourth and 3- branched on the sixth. They are longest and most prominent in.

In one fragment of more than 100 somites they con- tinued to the end. Lack of complete individuals makes it impossible to tell how far they extend in the entire animal. In the first setigerous somites the dorsal cirri are rather heavy. Farther back they are as slender as the gill branches. On the first five setigerous somites the ventral cirri are fleshy and sharp-pointed, and extend beyond the apex of the parapodium. On the seventh.
