1 1 , i ,, the Longitudinal diameter of the eye 3 — 4,4 °/ . The colour is uniform, brown 

 or grayish, without bands or spots 1 ); the belly and posterior border of the gill-eover 

 darkish. The scales arc small, relatively smaller than in the two foregoing forms and 

 have a somewhat wider distribution, as the\' extend from the end of the tail not 

 only to neai the base of the pectorals, but also to the neck (sometimes however, a 

 bare strip occurs in the mid die line of the back in front of the dorsal fin), as well as 

 on the underside- of the belly, which is scaled a considerable portion in front of the 

 anus, often just to the tip or even to the root of the ventral fins; in medium-sized 

 and adult individuals the scales spread out also on to the unpaired fins. The lateral 

 line is double, ventral and m e d i o 1 a t e r a 1 , most distinct in its course down towards 

 the anus. Pyloric appendages 2. The size reaches to 260mm.

Remarks on the Synonymy. 



/.. pallid-us was formed by R. Collett for two small Lycodes, taken by the Norwegian Xorth-Atlantic Expedition 

 in [878, north-west from Spitzbergen at 260—459 fathoms depth. In 1SS1— S2 the species was again taken in the Kara Sea 

 by tlit- Dijmphna Expedition, according to Liitken, who described n specimens from there and figured some of them. 

 Later, the same author mentions a number of specimens, taken by the Iugolf Expedition of 1896 at 8 stations in the cold 

 water between the Faeroes, Iceland and Jan Mayen. Lastly, X. Knipowitsch has recently elescribed a specimen, taken by 

 .1 Russian expedition to Spitzbergen. 



The species seems thus to have gradually gained recognition. In his latest treatise (on L. gracilis ) Prof. Collett has 

 meanwhile come to doubt how far L. pallidas land its probable young stage L. rossi ) is a good species, or if it possibly is 

 synonymous with L. gracilis M. Sars. 



The results my investigations have led to, are as follows: L. pallidas Collett is an independent species, which does 

 not show any near relation to L. rossi or to L. gracilis 1= L.valilii). L. pallidas Liitken from the Kara Sea is identical with 

 Collett's species, and the same holds for L. pallidas Knipowitsch. L. pallidas Liitken from the Ingolf Expedition belongs 

 likewise to the same species, but in certain regards displays a tolerably great amount of variation, and for some of the 

 specimens I have been led to form two separate varieties: similis (cf. p. 46) and squamiventer (p. 48). 



After these preliminary remarks had been written down. I have had the opportunity to examine an additional and 

 considerable number of specimens, especially from the Polar Depths and from the north-eastern Greenland; regard has also 

 been taken for these in my diagnosis, and they are deserving of special mention. 



Ly codes pallidus from the Iugolf Expedition. 

 Tab. IV, fig. 1 a, b, c, d, e. 

 There are n specimens in all from the seas north of the Fseroes (St. 138) and Iceland 

 I St. 124, 126); the depths varied from 293 — 495 fathoms. 



I give below the most important measurements of these specimens: 



Total length . 

 Length of the head 

 Instance from snout to anus 

 Height over the anus 



'1 Quite young individuals are certainly not known, but such is the condition in all the specimens to hand 

 whose total length is down to 117,5 mm.
