584 ^^- Stephensen. 



it is also found N. and S. of Bering Strait. The usual depth is 

 2—50 fm. 



Spirontocaris macilenta is known from W. Greenland : Fiskenæsset 

 (ca. 63° N.) (Krøyer), 6б°44' N., 56°08' W., ca. 175 fm., 69°29' N., 52° 

 56' W., 75 fm. and 69°59' N., 55^26' W., 116 fm. ("Tjalfe" Exped.); it 

 thus seems on the whole rare at W. Greenland. It is found further 

 at E. America : Halifax, Nova Scotia 26 — 57 fm,, St. Lawrence estuary 

 30 — 70 fm. and Labrador. W, of America it occurs in Bering Strait, 

 Bering Sea towards the American side, at Kamtschatka and in the 

 Sea of Ochotsk 16—100 fm. 



3B. Endemic Greenland littoral species. 



There are only two species here (common to W. and E. Green- 

 land), namely, Amphitopsis (Halirages) megalops and Ischyrocerus latipes. 



Amphitopsis megalops is very common at W. Greenland from 

 Godthaab (ca. 64° N.) to Upernivik (ca. 72^2° N.) (H. J. Hansen 1887, 

 Vanhoffen 1897); it has been taken further in Smith Sound (Ort- 

 mann 1901). On E. Greenland it occurs from Angmagsalik (ca. 67° N.) 

 to Danmarks Havn (ca. 77"" N.) (Buchholz, H. J. Hansen 1895, Dan- 

 mark Exped.). 



Ischyrocerus latipes is found at W. Greenland from Godthaab 

 (ca. 64° N.) to Kekertak (ca. 70° N.) (H. J. Hansen 1887) and at E. Green- 

 land in Scoresby Sound (H.J.Hansen 1895). 



The 2 following species may be taken as coming nearest to this 

 group. 



Nectocrangon lar is very common at W. Greenland and has also 

 been taken at E. Greenland (70°27' N. — ca. 77° N.) (H. J. Hansen 1895, 

 Danmark Exped.), but it is also found both N. and S. of Bering 

 Strait and goes S. to Vancouver Island and the Kurilles. 



Spirontocaris groenlandica is found at arctic N. America (Sars: 

 2nd "Fram"-Exped.) and is probabl}^ common along the whole of 

 the Greenland coast, both to the west and east, but is not found at 

 Jan Mayen, the Færoes or Iceland. At E. America the southern 

 boundary lies at Cape Cod. A record from Christianssund (Norway ; 

 G. O. Sars: Oversigt af Norges Crust., Forh. Vid. Selsk., Christiania 

 1882) is probably not correct. W. of America it is found both N. 

 and S. of Bering Strait. 



ЗС. Arctic littoral species occurring from Greenland to 



Spitzbergen or further east, but not N. of Siberia and in 



Norway not S. of Finmarken. 



Sclerocrangon boreas. Hippomedon Holboelli. 



Socarnes bidenticulatus. Aristias tumidus.
