﻿CRUSTACEA MALACOSTRACA. C3 



on the north-west coast also it lias been taken in Patriks I^'jord and Arnar Fjord in 20 to 50 fni.; on 

 the north coast several times in Sk:'dfandi and once in 1 10 fin. 



Distribn tion. Xornian notes the species from the Slietland Isles, bnt it is not improbable 

 that there was confusion with the later established A'. .S'ur.sii. In 1890 vSars writes that this species is 

 found on the west coast of Norway, it occurs at Lofoten and accordin^^ to his account mtist o-o much 

 further south, though he does not mention the limit. It is also found on the western and eastern 

 coasts of Finraark (Sparre-Schneider and Norman), in the whole of the Murman vSea and in the White 

 Sea (Birula); further in the Barents vSea {Hoek, vStebbing), is frequent at vSpitzbergen right up to 

 81° 14' N. L. at all depths between 5—8 fm. and down to 133 fm. (Ohlin, Doflein, Birula); it is comuKJU 

 in the Kara Sea in 10 to 100 fm. (vStuxberg, Hansen), has been taken in the Siberian Polar vSea at 

 115'/^ E. L. and 170° 17' E. L. (Stuxberg). On the east coast of North America it goes south to Mass- 

 achusetts Bay, ca. 42'. 5° N. L., and it has been taken at a number of localities from there to the St. 

 Lawrence estuary in 15 and down to 70 fm. (Smith, M. Rathbun). It is not found in the IJehriug 

 Straits and north of the American continent — i. e. between ca. iSo° and 80° W. L. The species has 

 been taken in 7 — o fm. and down to ca. 180 fm. ; it is a pronouncedh' arctic form. 



Remark.s. Ohlin (Bih. K. Sv. Vet. Akad. Handl. B. 27, Afd. IV, No. 8, ]x 37) has already 

 mentioned the superficial remark of Doflein's in "F'auna Arctica" that Sab. Sursii is a variety of .V. 

 si'ptcmcariiiata : Doflein has probabh- never seen .S'. Sursii. Ohlin also mentions the .S'. sfptcmcarinala 

 described and figured by Bate in the "Challenger" IMacrura; Bate says that his specimens agree luost 

 closeh' with Smith's S. Sarsii. which he considers as a "jjronounced variet\'". This last opinion is 

 incorrect; I liave never seeu anj- specimens wdiich in regard to the form of the rostrum were inter- 

 mediate between S. Sarsii and ,S'. sipfcii/carii/afa : also, there are very interesting differences in the 

 geographical and Ixathymetrical distribution of the two species. The largest Icelandic specimen, a 

 female with eggs, is from Bern F'jord and measures 76 mm.; from 70° 48' N. L. comes the largest East 

 Greenland specimen, likewise a female with eggs, 8i'5 mm.; the largest specimen from the Kara Sea 

 was 82 '5 mm.
