[From Introduction]
While collecting at a floating boat dock in Bodega Harbor, California, one of us (Belman) found a thick gelatinous sac attached to a colony of a hydroid (Obelia sp.). A polychaete was moving around inside the sac; this worm could not be identified as any polychaete reported from California (Hartman, Atlas of errantiate polychaetous annelids from California. Allan Hancock Foundation, Los Angeles, 1968; Atlas of the sedentariate polychaetous annelids from California, Allan Hancock Foundation, Los Angeles. 1969) and turned out to belong to the family Notophycidae, recently described from New Zealand (Knox and Cameron, Trans. Roy. Soc. New Zealand. Biol. Sei.. 12:73-85. 1970). The Californian specimen differs from the other known specimens in several respects and is described as a new species in a new genus.
The relationship between the family Notophycidae and related polychaetes was discussed in detail by Knox and Cameron (1970).
