IL Norwegian Sea 



(a) The Norwegian banks in the Norwegian Sea were only investigated 

 during the Spring period, with exception of the Romsdal Bank where the spawning con- 

 ditions were the same as in the North Sea. If the ling spawns later than in the spring, 

 the northern boundary cannot be fixed, but it may just be mentioned that in the invest- 

 igations so far made the young fish taken furthest to the north was found at the Lofotens 

 and this was over 15 mm. long. We may thus place the northern boundary south of 

 the Lofotens. 



(b) At the Faeroes the ling spawns in quantities all round the islands. 



(c) At Iceland the ling spawns on the south coast and on the south-west coast, in 

 quantities however only on the western part of the south coast. There is no spawning 

 on the north and east coasts. 



III. Atlantic Ocean 

 The species spawns in great quantities on the coasts of the British Isles. 

 The spawning decreases south of Ireland, but continues on the west coast of South 

 England, at the mouth of the Channel and in the north of the Bay of Biscay. 



14. Molva byrkelange, Walbaum 

 (see Chart fig. 18) 



I. Atlantic Ocean 

 The species only spawns above depths greater than 1000 M. or in the neighbourhood 

 of the 1000 M. curve, thus over the Atlantic deep-sea margin, with the southern boundary 

 near to the large Irish deep-sea Bank to the west of Ireland; from there along the west 

 coast of Scotland, at the Faeroes and on the south and west coasts of Iceland. 



The largest quantity of young fishes was taken in the area between the P'œroes and 

 Scotland. 



II. North Sea 



No spawning has been found in the North Sea, which is in agreement also with the 

 small depths. In the deep Skager Rak there is a very little spawning. 



III. Norwegian Sea 

 In the Norwegian Sea and over the Norwegian Sea banks no young fish have been 

 found. On the other hand, small fry of 10—35 mm. in length were taken in the deep 

 Norwegian Hjörunds Fjord, and we may therefore conclude that the species spawns in 

 other deep fjords, e. g. Trondhjem Fjord, where it is of common occurrence. 



15. Molva elongata (Risso) 



(see Chart fig. ig) 

 I. Atlantic Ocean 

 The species spawns only in great depths or in the neighbourhood of the 1000 M. line, 

 thus along the Atlantic deep-sea margin from the large Irish deep-sea Bank in south- 

 erly direction along the Bay of Biscay and presumably also further south, where however 

 no investigations were made. The species is also common in the Mediterranean.
