tubercles entire or bifid, few quatrifid. Elytra with long papillae 

 scattered on the surface as well as on external borders. 



Biology. — Dredged on bottoms of mud, mud with rocks, coral, 

 fine sand and pebbles. 



Material examined. — Off Labrador, Gulf of St. Lawrence (Bay 

 of Chaleurs), Nova Scotia, Maine, Massachusetts (Cape Cod), in 

 25 to 67 fathoms. 



Distribution. — Southern Labrador coast (Strait of Belle Isle) 

 to Massachusetts (Cape Cod). In 25 to 67 fathoms. 



Genus Antinoella Augener, 1928 



Type (designated by Uschakov, 1955): Antinoella sarsi (Malm- 

 gren, 1865). 



Both species have the anterior pair of eyes at the level of the greatest 

 prostomial width, visible dorsaUy. Elytra 15 pairs, easily deciduous. 

 Notopodia and neuropodia extending into conspicuous digitiform 

 acicular lobes. Setae golden yellow. Notosetae much thicker than 

 neurosetae, finely spinous, with short pointed to blunt smooth tips. 



Key to the New England Species of Antinoella 



1. Neurosetae of two kinds: With capillary tips and with slender, relatively 

 obtuse and slightly curved tips (fig. 7,h-j). Prostomium with anterior 



pair of eyes larger than posterior pair (fig. 7e) A. sarsi 



All neurosetae with long, flexible capillary tips (fig. 7,l-ni). Prostomium 

 with four subequal eyes (fig. 7k) A. angusta

 p. 62. 



Description. — Length up to 68 mm., width including setae up to 

 27 mm., segments 37, 38. Elytra large, thin, soft, smooth, with scat- 

 tered microtubercles and short delicate clavate papillae. 



Biology. — Dredged on bottoms of mud with gravel, stones. Swims 

 quickly by making use of its long parapodia; may be pelagic. Found 

 in stomach of haddock (43°39' N., 60°30' W., June 20, 1953, R. 

 Wigley). 



Material examined.— Off Labrador, Gulf of St. Lawrence (Bay 

 of Chaleurs), Massachusetts (Georges Bank), in 6 to 70 fathoms. 



Distribution. — Widely distributed in the Arctic. Also Iceland, 

 Norway to Great Britain, the Baltic, Labrador to Massachusetts, 

 Bering Sea, north Japan Sea. In 3 to 1,215 fathoms.
