Campylaspis rubicunda. Nymphon longitarse + N. micro- 

 Pycnogonum littorale. rhynchum. 



Phoxichilidium femoratum. — gracilipes-}- N.Stroemii. 



Pseudopallene circularis. Chætonymphon hirtipes. 

 Nymphon grossipes + N. mixtum. — macronyx. 



As will be seen, the 6 Nymphon-spec'ies are thrown together in 

 pairs, as this is frequently done in the literature, so that it cannot 

 be seen to which of the two species the localities mentioned belong. 



Hyas araneus is distributed from arctic America and Greenland 

 eastwards to Nova Zembla, but from here and almost to Bering Strait 

 is absent. The southern boundary is from Cape Cod — Channel — 

 N. France. It is found at 0—170 fm., mostly 0—40 fm. 



Hyas coarctatus is found from W. Greenland (but not E. Green- 

 land) to the entrance of the White Sea; the southern boundary is 

 Cape Cod — Channel. In the Pacific it occurs from Bering Strait to 

 Korea, perhaps to Amoy (24^2° N.). The distribution is thus essen- 

 tially boreal; 10— lOOfm.; rarely 100— 200 fm., perhaps 906 fm. 



Lithodes Maja has the same distribution but is likewise found 

 at E. Greenland though not in the Pacific. It lives usually at 40 — 

 100 m., greatest depth 291 fm. 



Eupagiirus pubescens is found at Greenland (rarely at E. Green- 

 land), Spitzbergen, Bear Island and extends to the Kara Sea, which 

 however it does not enter. The southern boundary is at 37°8' N. on 

 the American side, in Europe on the S. W. of Ireland. It lives 

 mostly at 40 — 100 m., seldom 640 fm. The temperature (according 

 to the "Ingolf") is 0.8° -8.4' С It is largest in the north, but is 

 not distinctly arctic. 



Sabinea Sarsii is found at W. Greenland : 65°35' N., 54°50' W., 

 80 fm., and 66°32' N., 55°84' W., 100 fm. (H. J. Hansen 1887), and 

 66^35' N., 55 54' W., 88 fm., l.o" С ("Ingolf"). It is not found at 

 E. Greenland, but occurs at E. America (Gulf of Maine and S. of Halifax), 

 Iceland, the Færoes and in the Skager Rak. Towards N. E. it is found 

 at E. Finmarken and reaches to the entrance of the White Sea. It may 

 go down to 388 fm. and has its widest distribution at places which 

 are not distinctly arctic; thus not found, for example, at E. Greenland. 



Spirontocaris Gaimardii goes from arctic America (Sars 2nd 

 "Fram" Exped.) over W. and E. Greenland to the Kara Sea. The 

 southern boundary is Cape Cod — W. Scotland — Firth of Forth — 

 Kiel Bay. Further, it occurs N. of Alaska and extends through the 

 Bering Strait to 57° N. on the west coast of America. 



Spirontocaris spinas is essentially arctic. It is found at W. and 

 E. Greenland, Spitzbergen, in the Barents Sea and in the White Sea.
