a male. The testes formed a fairly long chord, expanded in the 

 central part, as shown in hg. 2. This chord was, for a length 

 of abt. 36 cm. furnished with lobes and papillæ. 



Some days after the tinding of a T. arcticus in Dolmsnndet, 

 another specimen was driven on shore at Lerbotten in Alten 

 fjord, Finmarken. On the n /2 1916, a hsherman, Peder Esais- 

 sen, observed a large iish abt. 10 metres out from land, at 

 Lerbotten. The fish had a wound in the neck, but was still 

 alive apparent, and had caught hold of the weed at the bottom 

 with its jaws. The tail portion, however, was visible at the 

 surfa cé. So strong was its hold, that a hook had to be used 

 to lear it away. The specimen was, by request, sent in to 

 Trondhjem Museum for examination, and was found to be a 

 male dealfish. Total length from point of snout Lo slump of

tail (fin rays of the tail altogether lacking) was 211.5 cm. Golour 

 worn off; best described as greyish white in both sides. Dorsal 

 fin blood-red throughout its whole length. Pectoral fin dis- 

 coloured. No neck rays. 7 fairly large spines on the lateral 

 line near the tail. Maximal height of body 42.5 cm.; do. of 

 dorsal fin 14 cm. Length of head from point of snout lo posterior 

 margin of gill cover 28 cm. Diameter of ocular cavity abt. 8 cm. 

 Distance from anus to point of snout 113 cm. Length of diges 

 tive tract from beginning of gullet lo anus 104 cm. Testes of 

 same shape as in the specimen from Dolmsund. In neither case 

 was there any indication of venlral fin rays, but a shallow fur- 

 row on eilher side of the median line marked the posilion of the 

 venlral fins below and slightly in rear of the pectorals. In the 

 specimen from Allenfjord, each of these shallow furrows was 

 12 mm. long.
