(fig. 796) tapers to pointed end, with a pair of filiform anal cirri. 

 Colorless. 



Biology. — Dredged on bottoms of soft and sticky mud, muddy 

 sand, mud with stones, gravel, and tubes. Dark material found in 

 gut, evidently a bottom-deposit feeder. Females with large yolky, 

 coral-pink eggs, about 2 per segment dorsally; males with white sperm 

 masses; foimd in Maine in August (August 2, 1955, Ebenecook 

 Harbor) . 



Material examined.- — Gulf of St. Lawrence (Bay of Chaleurs, 

 26-33 fathoms), Maine (Ebenecook Harbor, Southport Island, 3 

 fathoms; north end Long Ledge, Sheepscot Kiver, 3 fathoms), Massa- 

 chusetts (Massachusetts Bay, Cape Cod Bay, Vineyard Sound, 10-27 

 fathoms) . 



Distribution. — Bering Sea, Greenland, Iceland, Faroes, Danish 

 waters to British Isles, Gulf of St. Lawrence to Massachusetts, 

 Antarctic. In 3 to 1,112 fathoms.

Paraonis fulgens Fauvel, 1927, p. 71, fig. 24, g-l. — Southward, 195G, p. 268. — 

 Marinov, 1959, p. 95, fig. 11. 



Description. — Length up to 30 mm., width up to 1 mm., segments 

 up to 120. Notosetae and neurosetae forming fan-shaped bundles of 

 capillary setae, some long, some short, limbate, strongly arched. 

 Neurosetae in posterior region (beginning on about setiger 50) with 

 1-2 additional neuropodial hooked crotchets (fig. 79/). Anal end with 

 3 filiform anal cirri, subequal or dorsal pair longer than median ventral 

 one. White with greenish-yellow pigment, pale pink in branchial 

 region, rest with greenish tint. 



Biology. — Found at low water in sandy beaches. Dredged on 

 bottoms of mud. They may be surrounded by thin tubes of sand 

 without any firmness, probably cemented by mucus. Deprived of 

 sand, they roU in a knot except for the anterior branchial part. 

 Females were found with large violet colored eggs (massed in the post- 

 branchial region) during August in Massachusetts (WeUfleet Harbor, 

 August 25, 1953). 



Material examined. — Maine (Sagadahoc Bay, Georgetown Island; 

 Middle Cove, Ebenecook Harbor, Southport Island), Massachusetts 

 (Stony Beach, Woods Hole; Lagoon Pond, Martha's Vineyard; 

 WeUfleet, Cape Cod). 



Distribution. — Denmark, British Isles to Enghsh Channel, 

 Maine to Massachusetts. Low water to few fathoms.
