external body is larger and somewhat oblong, and especially — but not exclusively —- in such cases the ovi- 
sacs are somewhat or considerably longer in proportion to breadth than usual. Large parasites are most 
frequently found on large hosts.

Davis Strait: Stat. 32: Lat. 66°35’ N., Long. 56°38’ W., 318 fathoms, temp. 3°9; 1 female on the

H, arcticus has been gathered at numerous places along the western coast of Greenland. The most 
northern locality is at about Lat. 76°8’ N., Long. 68°30’ W., 5—12 fath. (Sofia Exped., Sv. Riksmuseum). 
The other places are: Upernivik, Lat. 72°47’ N. (Capt. Ryder); Proven, Lat. 72°23’ N., 6—10 fath. (“Fylla” 
1886, Th. Holm); Disco Bay (Traustedt); Ritenbenk, Lat. 69°44’ N., 20—45 fath. (Sofia Exped., Sv. Riks- 
museum), and from the same colony. 2 old specimens determined by Steenstrup & Liitken; Godhavn, Lat. 
69°14’ N. (specimens in Sv. Riksmuseum secured by Amondsen, and in the Copenhagen Museum gathered 
by Traustedt) ; Claushavn, Lat. 69°05’ N., 15—20 fath. and 20 fath. (Oberg, Sv. Riksmuseum) ; Egedesminde, 
Lat. 68°42’ N., 5—10 fath. and 30—40 fath. (Oberg, Sv. Riksmuseum), and at the same locality specimens 
have been gathered by Traustedt and especially by Levinsen; Northern Strémfjord, ab. Lat. 67°40’ N. 
4I—2I m., temp. + 0.5°— + 0.5°, and 200—240 m. (Dr. V. Nordmann leg., K. Stephensen 1913) ; Holstens- 
borg, Lat. 66°56’ N., ro fath. (Prof. D. Bergendal) ; Ikertokfjord, Lat. 66°40’ N. (“Fylla’”’, Th. Holm) ; Sukker- 
toppen, Lat. 65°25’ N., 60—7o0 fath. and 200 fath. (respectively Oberg and Amondsen, Sv. Riksmuseum), 
besides in 5—20 fath. (“Fylla’, Th. Holm); Godthaab, Lat. 64°11’ N. (Amondsen, Sv. Riksmuseum); Lat. 
63°47’ N., Long. 52°56’ W. (J. Lindahl, Sv. Riksmuseum); Julianehaab, Lat. 60°43’ N., 10o—25 fath. (Sofia 
Exped., Sv. Riksmuseum); Bredefjord, ab. Lat. 601/.°—61° N., at 3 stations (see Stephensen, 1916). —- At 
East Greenland the parasite has been secured at Tasiusak, Lat. 65°37’ N. (II. Amdrup Exped.); besides in 
Danmarks Havn, Lat. 76°45’ N., 5—8 fath., and at Hvalrosodde, Lat. 76°55’ N., o—5 fath. (Danmark 
Exped., K. Stephensen 1912). ——- Levinsen mentions it from Eunoé Oerstedi Mgrn. ; locality unknown. 
At Iceland H. arcticus is less common. It has been gathered at North-West Iceland in Dyrefjord 
(Mag. sc. W. Lundbeck), and at East Iceland in Berufjord (Torell, Sv. Riksmuseum). — Finally secured 
south-west of the Feroes at Lat. 61°15’ N., 9°35’ W., ab. 460 fath., on Harmothoé mollis Sars (the “Thor’’, 
Dr. Joh. Schmidt). 
Distribution. — A gigantic specimen of Harmothoé nodosa Sars with 2 parasites on the head from 
Lat. 72°8’ N., Long. 74°20’ W., 1o—23 fath. (E. Nilsson, Sv. Riksmuseum); Gulf of St. Lawrence, on Nychia 
Amondseni (according to Mc’Intosh, 1874); Kara Sea, 49—51 fath., on Havmothoé imbricata L.. (H. J. Hansen, 
1886); Gulf of Georgia, Puget Sound, on Harmothoé (Kathleen Haddon, 1912). Finally Gravier (1912) states 
that H. arcticus is found on three species of Polynoids from the Antarctic, but as I do not believe in bipolarity 
of any species I suppose that Gravier’s specimens must belong to an allied species.
