Lönnberg writes (I.e. p. 13): »A very interesting observation 

 was made concerning ^the habits of the Polar-cod, which was 

 found abundantly swimming the surface of the sea round the 

 drifting ice even in such places where the depth of the ocean 

 was 2000 metres and more». Bay is inclined to believe that 

 Gadus saida — at least at a young age — leads a pelagic life. 

 And Lönnberg writes: "It thus leads sometimes a pelagic 

 life». Jensen on the contrary in his diary is of the opinion, 

 that G. saida evidently is no pelagic species whatever, no 

 more than the Amphipods (and masses of Diatoms) which are 

 found together with it on the ice-foot; we «have here to do 

 with a peculiar life of shore species which live out here among 

 the sheets of ice». 



The three largest ones (223, 254, 267 mm.) of the speci- 

 mens at my disposal are females, while the largest male only 

 measures 185 mm. In the largest female caught July 25*^, the 

 eggs are 0.35mm. in diameter: in a 187 mm. long female caught 

 Sept. le*"", the diameter of the large&t eggs is 0.6 mm. 



The numbers of rays in 6 specimens are as follows :

The fry (of 45 mm. and more) is pigmented on back and 

 flanks with dark cross-formed or stellated chromalophores. In 

 larger young ones the dark chromalophores are sometimes amassed 

 in some places towards the back, and produce an intimation of 

 transverse bands; the distal margins of the dorsal fins and partly 

 also of the anal fins are frequently strongly pigmented. 



In fig. 1 a & b, plate ХП is represented a young one of the 

 Polar-cod in natural size (45 mm. long). It reminds us about
