FAMILY SPHAERODORIDAE 



Key to genera and species 



Setae compound and falcigerous (EphesicUa) 2 



Setae simple, hooked (SphaerodonnH) No N.C. record 



Only 6 large papillae across dorsum of each segment £■. rlaporvdii 



Ten to twelve large papillae across dorsum of each segment 



(E. mi,ii,tum) No N.C. record 



Ephesiella claparedii {(Jreeff, 1866) 



Sphaerodoi^im claparedii. - Fauvel, 1923: :}79, 

 Fig. 149 d, e. 



Dcfcriptinu. — Body stout and ovoid, 2 mm 

 long, with 18 segments. Prostomium indistinct, 

 papillose. Each segment with a transverse row 

 of six large papillae across dor.sum and a band 

 of smaller papillae across ventrum. No small 

 papillae among large dorsal ones. Parapodia 

 uniramous and cylindrical with three oval pa- 

 pillae distally. About 10 falcigerous compound 

 setae per foot; blades faintly curved and uni- 

 dentate. 



Remarks. — The single specimen obtained was 

 a female containing large eggs. It agrees very 

 well with Fauvel's de.scription except it lacked 

 the small irregularly arranged papillae among 

 the large dorsal ones. According to Hartman 

 (1965b), this species should be referred to Spliae- 

 rodoridiiini Liitzen, but according to Pettibone 

 (1963a), it should be referred to Ephcsiella 

 Chamberlin of which Sphaerodoridiinu is a 

 synonym. 



Records. — One specimen from 200 m off 

 Beaufort (*). This is a new record for the 

 United States. 



Distributio)!. — English Channel and Ireland; 

 intertidal to a few meters.
