﻿CRUSTACEA MALACOSTRACA. eg 



x\t Iceland this species has several times been taken on the west side, from Arnarnfcs to 

 Reykjavik and Skagi; on the east side it has been fonnd in Mid I'jord, Rode Fjord and Bern Fjord; 

 the depths were from 3 to 52 fm. At the Faeroes it has been taken at Thorshavn and several times 

 fnrther ont to sea in 30, 60 and 100 fm. (Th. IMortensen). 



Distribntion. It has been fonnd at Oban, west coast of vScotland, at 56' ^ N. L. (Norman), 

 and is mentioned from the Irish vSea (Walker)'; a single specimen has been taken in tlie innermost part 

 of the Kattegat at Samso (Meinert); Goes gives it from Bohnsliin, and Appelhif states that he has seen 

 a typical specimen in the Kristineberg collection. In Norway it goes sonthward at least to ca. 59^/3° 

 N. L., 30— 40 fm. (G. O. Sars); and has been taken at PJergen and Christian.ssund onlv "at great depths" 

 (Danielssen); it is known from the fjords near Tromso (.Sp. Schneider), bnt not from East i-'inmark 

 (Norman), it occnrs throngh the whole of the Mnrman vSea — is commonest here according to Birula 

 in 40 — 50 fm., bnt is fonnd in 4 and down to 175 fm. — and penetrates into the White Sea. It has 

 .several times been taken in the Barents Sea in 67 to 124 fm. (Hoek, Stebbiug), is common at Spitz- 

 bergen (several anthors), but on the other hand it has not been taken near Franz Joseph Land, in the 

 Kara Sea nor along the whole of the north coast of Asia. On the east coast of North America it has 

 frequently been taken on the tract from Cape Cod to off Nova vScotia, in depths from 5 to 90 fm. 

 (S. I. vSmith, M. Rathbnn); it is likewise fonnd in the St. Lawrence estuary (Whiteaves), at Labrador 

 (Packard), on the north side of Alaska, in Bering Straits, the Bering Sea, at the Alaskan Peninsula and 

 at the Aleutian Islands, in 5 — 91 fm. (Mary Rathbnn), at Kamtschatka (Richters), lastly at Queen Char- 

 lotte Islands and Vancouver, 50° N. L. (Smith). — How far the species is found on the long tract of 130 

 degrees along the north coast of Asia is not 3'et known. The greatest depth from which it is known 

 with certainty is 175 fm., the notices from 200 and 240 fm. I cannot consider absolutely trnstworth\'. It 

 has been taken in so low a bottom-temperature as ~ 1-42° ((3hlin), l>ut it also occnrs on groiuuls with 

 low positive temperatures. 



Remarks. I have now come to the conclusion that the following species is not a \'aricty of 

 S. spiiins. The differences will be dealt with under ^S'. Lilljiborgii.
