CRUSTACEA MALACOSTRACA.

At Iceland this species has several times been taken on the west side, from Arnarnses to 

 Reykjavik and Skagi; on the east side it has been found in Mid Fjord, 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 

 further out to sea in 30, 60 and 100 fm. (Th. Mortensen). 



Distribution. It has been found at Oban, west coast of Scotland, at 56V2 N. L. (Norman), 

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

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

 a typical specimen in the Kristineberg collection. In Norway it goes southward at least to ca. 59^-,° 

 N. L., 30 — 40 fm. (G. O. Safs); and has been taken at Bergen and Christianssund only "at great depths" 

 (Danielssen); it is known from the fjords near Tromso (Sjj. Schneider), but not from East Finmark 

 (Norman), it occurs through the whole of the Murman Sea — is commonest here according to Birula 

 in 40 — 50 fm., but is found 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, Stebbing), is common at Spitz- 

 bergen (several authors), 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 Scotia, in depths from 5 to 90 fm. 

 (S. I. Smith, M. Rathbun); it is likewise found 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 Rathbun), 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 yet 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 trustworthy. It 

 has been taken in so low a bottom-temperature as f- 1-42° (Ohlin), but it also occurs on grounds with 

 low positive temperatures. 



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

 S. spimis. The differences will be dealt with under S. Lilljcborgii.

Occurrence. The "Ingolf has brotight home this species from two stations: 

 Davis Straits: St. 31: 66° 35' N. L., 55° 54' W. L., 88 fm., temp. i-6°; 6 spec. 

 North-West of Iceland: St. 129: 66° 35' N. L., 23°47'W. L., 117 fm., temp. 6-5°; 11 spec. 



I I agree with Appellof in his suggestion that Walker probably referred a specimen of 5 Lilljeborgii to S. spimis, 

 consequently that 5. spimis has not been found in the Irish Sea.
