 Anaitides groenlandica Treadwell, 1948, p. 27, fig. 146.— Eliason, 1962, p. 230. 



Description. — Length up to 450 mm., width up to 9 mm., seg- 

 ments up to 700. Basal part of proboscis with 12 longitudinal rows 

 of papillae (6 rows on each side) with 10-20 papillae per row. Color, 

 in life: deeply pigmented bright metallic green with uTegular brown 

 markings, dark greenish brown or deep reddish blue, with cirri tan 

 to dark brown; color, preserved: deeply pigmented, iridescent reddish 

 blue with cirri reddish bro\vTi, or tannish with middorsal longitudinal 

 iridescent bluish band, dorsal cirri greenish brown. 



Biology. — Found at low water in sand, in holdfasts of algae, on 

 pilings. Dredged on bottoms of mud, sand, sandy mud, and various 

 combinations of mud, gravel, stones, with shells, worm tubes, algae, 

 etc. Found in the stomach of the cod Gadus callarias (Miscou Bank, 

 Gulf of St. Lawrence, July 30, 1952, May 27, 1953, June 25, 1954), 

 in the plaice Hippoglossoides platessoides (Bay of Chaleurs, July 27, 

 1957), and in the stomach of haddock (Georges Bank, 1953 and 1954, 

 R. Wigley). According to Thorson (1946), they lay oval, ohve-green, 

 gelatinous egg masses which adhere by short stalks to algae; larvae 

 hatch as large trochophores and have a long pelagic life; larvae occur 

 mainly in March to September. 



Material examined. — Off Labrador, Gulf of St. Lawrence, Nova 

 Scotia, and Newfoundland to off North Carolina, in low water to 866 

 fathoms. 



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

 Norway to English Channel, Hudson Bay to North Carolina, Bering 

 Sea to southern California, north Japan Sea. In low water to 866 

 fathoms.

Description. — Length up to 150 mm., width up to 3 mm., segments 

 up to 200. Basal part of proboscis with 12 longitudinal rows of 

 papillae (6 on each side), with 8-12 papillae per row. Color, in life: 

 white with middorsal longitudinal brown band (almost continuous) ; 

 also may have dark pigment laterally at the bases of the parapodia 

 (thus 3 longitudinal pigmented bands) ; dorsal cirri with large brown 

 spot in center; may have additional paired yellow spots near the 

 bases of the parapodia.
