the N. Stroemii of Sars so far north as 65 34', in the Davis Strait; on the other hand, however, I 

 must acknowledge that most of the specimens that I after Sars temporarily determined as N. Stroemii, 

 are from more southern stations (2, 3, 4, 35, 44, 67), while those that I determined as N. gracilipes, 

 are from more northern ones (29, 32, 106). It is, however, a well known fact that many animals, for 

 inst. among the Crustacea, in the higher latitudes by and by assume a somewhat different shape and 

 especially a more considerable size; I shall only remind of so well known animals as Gammarus 

 loc^lsta and Amathilla Sabinei. 



If N. grossipcs be taken in a so wide conception as here, its distribution will be very consider- 

 able. From the arctic seas around Franz-Joseph Land (Heller), the Barents Sea (Hoek), the Kara 

 Sea (Hansen), and off Grinnell Land (Miers) it stretches in the west down along the eastern coast 

 of North America (Wilson), and in the east along the Finmark (Sars) into the Norwegian Sea, and a 

 little into the Atlantic, as also through the North Sea along the eastern coast of England (Goodsir), 

 and to the east quite into the Skager Rack and the Cattegat.

Occurrence. The Ingolf-station 29 gives it to be taken in the Davis Strait close to the 

 western coast of Greenland, at a depth of 68 fath. 



Further it is found at the Zoological Museum from the following localities: Baffin's Bay 72 

 4o'Lat. N. 57 1 5' Long. W., 118 fath. (Fylla, Holm); 69 54' Lat N. 55 34' Long. W. , 50 fath. (idem), 

 and from the Davis Strait, along the western coast of Greenland till Igaliko (K. J. V. Steenstrnp), and 

 Frederikshaab (Lundbeck). 



Distribution. Sars, I.e. p. 78, states it as occurring at Greenland (that is the western coast, 

 Kroyer), the Barents Sea (Hoek), the eastern coast of North America (Wilson), and the eastern 

 coast of England (Hoek), as he also himself has it from the whole Norwegian coast and from the 

 Kara Sea.
