I refer this species to the genus Eurythoe. The caruncle is 

 somewhat lobed at the edges. The setae of the dorsal feet are, 

 some linear, svibarticulated in several places, others linear and sub- 

 bifid, the terminal branch long and slender, whilst a third set are 

 stouter and serrated. The setae of the ventral feet are considerably 

 stouter than the dorsal setsD, and are all bifid and quite smooth.

* Brown confounds this worm with the Teredo or whipworm ! As Pallas 

 conjectures, the specimen he had for inspection miglit jirobably have been 

 taken burrowing in one of the holes made by the Teredo.
