Tlie variety squainiventer was taken t)y the Ingolf Expedition of i8g6 east from Iceland 

 (St. 105, 104, 10 1), where tlie deptlis were 537 957 fathoms and tlie bottom-temperature o--]\.o \\Z. 

 (5 specimens); north from the Fjcroe Isles (St. 141) at 679 fathoms and bottom-temperature 

 — o°6C. ( I specimen); and by the Michael Sars in 1902 off the Sh etIaud-Norwa v Slope (63° 

 7' N.L. i" 38' E.L.), where the depth was 650 fathoms and bottom-tomperatm-e under o'' C. (6 specimen.s). 



L. pallidas lives in polar waters; in southern latitudes therefore, it is first met with at great 

 depths (300 fathoms and deeper) but in high arctic seas it comes up quite to the sublittoral zone.

Body zoarciform, yet relatively- more elongated than in most other species of 

 the genus Lycodes, the height o\er the anus being onl\ 8,2",, of the total length; 

 the length of the head is 19,9",, of the same length, the distance between the snout 

 and the anus 37 "o- The colour is uniformly of a ruddy brown-gra\-. Scales are 

 wanting. Lateral line double, ventral and medi olateral, most distinct in its course 

 towards the anus. The size (of the single specimen) 148,5 mm.

Distribution. Between Jan IMayen and Iceland, loio fathoms. 



Only one specimen of this species, which was placed b\- Liitken with L. frigidns. is at hand 

 for investigation; it is a male. 



The most important proportions are the following: 



Total length 148,5 mm. 



Length of the head 29,5 — 



Distance between snout and anus. . 55 — 



Height over the anus 12,25 — 



The form of the bod\' is more slender than in most other species of the genns Lycodes, the 

 height over the anus being onh' 8,2 " o of the total length. On the trunk the height is almost uniform 

 and the tail tapers very gradually down to the tip. The trunk is somewhat compressed, its thickness 

 being i' 2 times in the height, and the tail becomes gradually more and more compressed. The anus 

 lies a little behind the termination of the anterior third of the bod\', the distance between tlie snout 

 and the anus being 37 °o of the total lengtli. 



The head is broad, flat in front and tolerably short, its length being 19,9 "n of the total 

 length. The height over the crown is somewhat greater than the breadth at the same place, but 

 further forward the head becomes very low without at the same time losing in breadth; the end of 

 the .snout is blunt, but low, seen from above it is broadly rounded off. The eyes are small, so that 

 their longitudinal diameter is scarcely ' gth of the total length of the head; they are placed high up, 

 on the very margin of the forehead, but at a fairly clear distance from one another amounting to quite one
