In relation to the total length, the length of the head is 25,7 ° 0) the distance 

 between the snout and the anus 47,3 ° ,,, the height over the anus 12,7 °/ , the lon- 

 gitudinal diameter of the eye 3,3 " ,., the length of the pectoral 16,8 ° . The colour 

 is gray-brown with 7 broad, dark cross-bands; a light baud across the neck. The 

 scales extend to a point under the anterior end of the dorsal fin. The lateral line is 

 raediolateral. Pyloric appendages 2. The size (of the single specimen, a female),

L. liitkenii was established in 1SS0 by R. Collett for a species, a single specimen of which, 370 mm. long, was 

 taken by the North-Atlantic Expedition W. from North Spitzbergen, where the depth was 459 fathoms and the bottom-tempe- 

 rature — I s C; it was previously described by the same author in 187S under the name L. reticulatus Reinhardt, an error 

 that Collett himself corrected in the interval after he had examined the real L. reticulatus in the Zoological Museum of 

 Copenhagen. 



Later, /,. liiikenii was reported, on the authority of Liitken. to have been again found in numbers both by the 

 Dijmphna and Ingolf Expeditions. In 1S86 he referred no less than 28 specimens from the Kara Sea to L. liiikenii; I have 

 come to the conclusion however, that the largest of these specimens must lie referred to L. rossi Malmgr., and that the 

 others constitute a new species, belonging to the scaleless Lycodes: Lycodes agnosius (cf. p. 791. In 1S98 further, Lvitken 

 mentioned quite briefly that the Ingolf had taken 6 L. liitkenii S. from Jan Mayeu. Five of these however, are a colour- 

 variety of Lycodes pa/lidus Coll. var. similis mihi (cf. p. 46). The sixth specimen was rightly determined according to my 

 earlier opinion, as expressed in my preliminary report 011 the Lycodes of the Ingolf Expedition (1. c), but after examining a 

 whole series of similar specimens in the Stockholm Riks-Museum, brought from East Greenland by the Nathorst-Kolthoff 

 Expeditions, I have come to a different conclusion, namely: that we have here a form which cannot be separated from L.sc- 

 minudus Reinhardt, and must be considered as a colour-variety of this species (see further p. 72J.

This form has been described in detail and well illustrated by Collett in his work on the 

 fishes of the North-Atlantic Expedition. After I had learnt, through the kindness of Prof. Collett, 

 to know it for myself, I became quite at one with him in believing it to be a distinct species from 

 A. reticulatus Reinh. as C. has well shown (1. c. p. 104). In certain respects, L. liitkenii is nearly re- 

 lated to L. seminudus, as we now know it with the banded colour-markings, and I shall therefore 

 briefly discuss the mutual relations of these forms. 



If the single female specimen of L. liitkenii is compared with a specimen of L. seminudus of 

 the same sex and similar size, they agree essentially in the most important proportions of the body; 

 yet /.. liitkenii is a less slender form, as will be seen:
