Si 



the mouth of Chatang-a Hay (75" N.L. 113^ 30' E.L.), where the depth was 15 fathoms and the bottom- 

 temperature - 0,8° C. 



The specimens of the Dijmphna Expedition were taken in the Kara Sea at a depth of 46—100 

 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 nnn. in diameter; 

 the date of the catch is not forthcoming. 



Comparison with allied forms. 



A scaleless Lvcodes has not been known hitherto from the European-Greenland coasts. From 

 Arctic North America however, 2 species were known, whicli are described as perfecth- naked, and set 

 up by Bleeker therefore as a separate genus: Lycodalepis, nameh- L. turnerit Bean (Ala.ska, Bering 

 Straits) and L. mncosus Richardson (Northumberland Sound, Cumberland Gulf). The scaleless L\codes 

 from the Kara Sea presents great similarity- to L. titrnerii amongst these, the latter's i)roportious 

 according to Bean') being as follows: 



Total length 33° mm- 



Length of the head iu % of the total length 23 



Longitudinal diameter of the eye — — 2,5 



Distance of the anal fin from the snout — — 51 



But L. turnerit has 18 rays iu 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^) 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 & Evermanni) have given of Bean's type-specimen. 



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

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

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

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

 weak development of the scaly covering (e. g. L. seminiidus], present transitions between entirel\- 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. platyrliinus niihi).
