 Skjællene smaa, runde, nedtrykte i Huden. Sidelinie 

 tilstede, ofte mindre tydelig, undertiden dobbelt.

 mindre, end ' t af Pectoralemes Længde. Gjælle-

 Palatinbenene. Pseudobranchier tilstede: Analpapille

Af denne i flere Henseender mærkelige Slægt have de 

 seneste Aars Undersøgelser efterhaanden bragt for Dagen 

 et ikke ringe Antal nye Former, saa ledes at den er kom-

 kjendte arctiske Dybvandsfiske 1 .

 The southern limit of its range is probably Bohuslen, in 

 Sweden, one or two individuals having been obtained off 

 Gothenburg (58° X.). 



'It is an interesting fact, that individuals taken on the 

 southern coast of Norway and Sweden, where the tempera- 

 ture of the water is comparatively high, diller 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, 

 circular, imbedded in the skin; lateral line present, 

 frequently indistinct, sometimes double. Eyes mode- 

 rate, jaws 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 oj the eye, or less than */ 4 oj 

 the length of the pectorals. Gill-opening rather 

 narrow; branchial membrane disconnected on the 

 inferior surface of head. Teeth in the jams, and, as 

 a rule, also on the vomer and palatine horn's. Pseu- 

 dobranchiæ present: anal papilla and swimming- 

 bladder wanting. Pyloric appendages 'J, or altogether 

 wanting. 



Within the last few years the labours of ichthyolo- 

 gists have brought to light 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 tisb.es yet 

 known 1 .
