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

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

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

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

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

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

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

 conjectures, the specimen ho had for inspection might probably have been 

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