The specimens of the Dijmphna Expedition were taken in the Kara Sea at a depth of 46 too 



fathoms. I give below the proportions of 11 specimens chosen according to size:

In the 1S5 mm. long female the eggs are of a considerable size, namely 4,5 mm. in diameter; 

 the date of the catch is not forthcoming. 



Comparison with allied forms. 



A scaleless Lycodes lias not been known hitherto from the European-Greenland coasts. From 

 Arctic North America however, 2 species were known, which are described as perfectly naked, and set 

 up by Bleeker therefore as a separate genus: Lycodalepis, namely /.. turnerii Bean (Alaska, Bering- 

 Straits) and L. mucosus Richardson (Northumberland Sound, Cumberland Gulf). The scaleless Lycodes 

 from the Kara Sea presents great similarity to /.. turnerii amongst these, the latter's proportions 

 according to Bean') being as follows: 



Total length 330 mm. 



Length of the head in % of the total length 23 



Longitudinal diameter of the eve 2,5 



Distance of the anal fin from the snout 51 



lint L.turnerii has iS rays in the pectorals, 85 in the dorsal fin, and 67 in the anal; and these 

 data can scarcelv be regarded as resting on wrong counting, since Scofield 2 ) in a second specimen 

 has found: P. 18, D. 86, A. 67. Nor does the colouration agree, so far as I can discern from the figure 

 which Jordan & Eveniiaiiu ; | have given of Bean's type-specimen. 



Until further information is forthcoming, I must therefore consider the scaleless Lycodes from 

 the Kara Sea and Chatanga Bay a separate species. The European Lycodes-fauna is thus enriched 1>\ 

 an interesting form which has hitherto been misunderstood. I cannot find however, am sufficient ground 

 for adopting the genus-name Lycodalepis proposed by Bleeker, since we know forms which, in their 

 weak development of the scalv covering (e.g. L. semimidus\ present transitions between entirely naked 

 and perfectly scaled species; and other characters do not exist which might be the basis for a generic 

 separation of the naked species, so far as I can see (cf. for the rest p. 5, with remarks on the likewise 

 scaleless L. platyrhinus mihi).
