Reconh.—On Beaufort in 120-200 m (17, 

 21, *). 



Di-<t)-ibiitl())i. — North Atlantic from Sweden 

 and Greenland south to the West Indies; ? 

 Australia; from the edge of the continental 

 shelf to abyssal depths. 



Apltrodito sp. 



Rcnuirks. — The two juveniles collected may 

 belong to Aphvodita liastata Moore, reported by 

 Pettibone (1963a) from the Gulf of St. Lawrence 

 to Chesapeake Bay in 4-2,000 m. 



/?rrorf/.s'.— Off Beaufort in 200 m (*). 



Aphrogenia sp. 



Fi^TJic la, I) 



Description. — Body 2 mm long, broadly oval. 

 Dorsal felt poorly developed. No eyes, no ocular 

 peduncles. Notosetae in a graded series; very 

 fine ones forming felt, stouter cylindrical forms 

 (P^igure la) tapered to fine tips with a double 

 row of granules near end. No barbed setae nor 

 serrated sabre-setae. Neuroseta (Figure lb) 

 long, stout and spurred, with two to five spines 

 on longer limb. 



R< nnn-ks. — The single specimen is a ju\enile, 

 but the lack of barbed setae or sabre-setae 

 distinguishes it from both H( I'moiiia and Poiito- 

 g(iii(i. It appears to be close to Aplirogi iiia 

 alhu Kinberg, recorded from St. Thomas Island 

 in the West Indies, but it lacks the stout 

 notosetae with strongly curved tips figured 

 by Kinberg (1858) for a 15-mm specimen. 



Record. — One juvenile off Beaufort in 200 m 

 (*).
