LYCODIX.^J. 



51 



The variety sqtiamiveiiter was taken by tlie I ugolf Expedition of 1896 east from Iceland 

 (St. 105, 104, loi), where the deptlis were 537 -957 fathoms and the bottoni-teniperature 0^7 to- -11 C. 

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

 — o°6C. ( I specimen); and b\' the IMichael Sars in 1902 off the S li e tl an d -Norwa \- Slope (63° 

 7' N.L. I" 38' E.L.), where the depth was 650 fathoms and bottom-temperatnre under o' C. (6 specimens). 



L. pallidns 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 snblittoral zone.

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

 and the anus 37%. The colour is uniforml\" of a rudd\- brown-gra\'. Scales are 

 wanting. Lateral line double, \- e n t r a 1 and m e d i o 1 a t e r a 1 , most distinct in its course 

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

Distribution. Between Jan Ma}'en and Iceland, loio fathoms. 



Onh- one specimen of this species, which was placed b\" Liitkeu with L. frigidiis. is at hand 

 for in\estigation; it is a male. 



The most important proportions are the following: 



Total length i48)5 i""!- 



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 genus Lycodes^ the 

 height over the anus being only 8,2 '^' \, of the total length. On the trunk the height is almost uniform 

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

 being i' \ 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 the snout 

 and the anus being 37",, of the total length. 



The head is broad, flat in front and tolerably short, its length being 19,9",, 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; the\- are placed high up, 

 on the ver\- margin of the forehead, but at a fairh- clear distance from one another amounting to quite one
