Report on the Malacostraca, Pycnogonida and some Entomostraca. 601 



180 m., 73°20'N., 2Г20' W., 70 m. and 74°52' N., 17°16'W., 350 m. 

 (Ohlin 1901), as also Jan Mayen (Ohlin 1901), Iceland, Spitzbergen, 

 Barents S^a, Kara Sea, Varanger Fjord, Scotland, Shetland (61°22' N., 

 1°25'W., 496 m., Zirwas 1910), Ireland, Bay of Biscay and eastern 

 N. America. The depth varies from 10 to 1360 fm. So far as I 

 know, this species is the only deep-water bottom-form, which seems 

 to be equally distributed in the arctic and boreal regions, comp. 

 Janira maculosa. 



Idothea metallica has a very wide distribution. At W. Greenland 

 it has been found at 64°46' N., 53°35' W. (H. J. Hansen 1887), at 

 Iceland and S. of Cape Sable (south point of Nova Scotia). Further, 

 between the Azores and Newfoundland 47° N., 37^ W. (H.J.Hansen 

 1887, p. 188), S. W. Ireland and widely distributed in the Mediter- 

 ranean (Tattersall 1905), Monte Video, between Patagonia and Mag- 

 ellan Straits, N. S. Wales and Borneo. Lastly, it has been taken at 

 a number of localities in Japan (H. Richardson, Proc. U. S. A. Nat. 

 Mus., vol 37, 1909, pp. 107—08). It seems thus to be practically cos- 

 mopolitan. 



Eclotia nodulosa is known from certain localities at W. Greenland 

 only from 6646' N. and Godhavn (ca. 69° N.). Further, it has been 

 taken at eastern N. America, W. Spitzbergen and in the Kara Sea, 

 as also in the northern part of the Pacific (Harger). 



Janira maculosa has only been taken at 2 places at W. Green- 

 land, namely, 66°32' N., 55°34' W., 100 fm., and 72°32' N., 58°51' W., 

 116 fm. (H.J. Hansen 1887) and E. Greenland: 69°25'N., 20°0Г W., 

 167 fm. (H. J. Hansen 1895). Further, at Iceland, Barents Sea, whole 

 of Norway, Kattegat, Great Belt, Baltic, Holland, north coast of France, 

 British Isles and S. W. Ireland (Tattersall 1905). The distribution of 

 this species thus resembles somewhat that of Calathiira brachiata, 

 but has only 3 arctic localities. 



Jixra marina (= J. albifrons) has very much the same distribution ; 

 this may be given as follows (cf. Apstein, teste Zirwas 1910) : 72°— 40° N., 

 75° W. — 55° E. Though in Greenland as elsewhere, where it occurs, 

 it lives in quite shallow water, it has curiously enough only been taken 

 at 4 places at W. Greenland, for which the records of the locality are 

 certain; it may however be considered to be much more widely 

 distributed. It has not been taken at E.Greenland; on the other 

 hand, it is known from the Mediterranean. 



Munna Fabricii also has almost the same distribution, but in 

 W. Greenland goes right up to ca. 71° N. and has been taken in arctic 

 America (Sars 2nd "Fram" Exped.); it is also known from Jan 

 Mayen (Koelbel). 



Munna Kroeyeri is found in the same regions, but is not known 

 S. of the Channel Islands.
