haul with a net. in the Porsanger Fjord, West Finmark- 

 The southern limit of its range is probably Bohuslen, in 

 Sweden, one or two individuals having been obtained off 

 Gothenburg (58 o N.). 



It is an interesting fact, that individuals taken on the 

 southern coast of Norway and Sweden, where the tempera- 

 ture of the water is comj)aratively high, differ in no respect 

 from those met with in the frigid expanse of ocean at the 

 northern extremity of Spitzbergen.

Body elongated, as a rule scaled. • Scales small, 

 ciroidar, imbedded in the skin: lateral line present, 

 frequently indistinct, sometimes double. Eyes mode- 

 rate, j'atos without fringes: upper jaw longer than 

 lower. Fin-rays soft, articulated: caudal indistinct, 

 continuous with the dorsal and anal. Ventrals pre- 

 sent, placed on the throat, each furnished with a few 

 exceedingly slender rays, of a, length less than the 

 longitudinal diameter of the eye, or less than '/^ oj 

 the length of the pectorals. Gill-opening rather 

 narrow: branchial membrane disconnected on the 

 inferior surface of head. Teeth in the jaios, and,- as 

 a rule, also on the vomer and palatine bones. Pseu- 

 dobranchiæ present: anal j^d'P^ttO' cind swimming- 

 bladder wanting. Pyloric appendages 2, or altogether 

 wanting. 



Within the last few years the labours of ichthyolo- 

 gists have brought to Hght a considerable number of new 

 forms belonging to this, in many respects, remarkable genus, 

 which is now shown to comprise a greater number of 

 species than any of the other Arctic deep-sea fishes yet 

 known ^
