The height over the anns anronnts in general to 8 — 1 1 °/o of the total length. 

 The lengtli of the head in tlie males is 19,6 — 23,8";o, in the females 18,8 — 21, 4",, of the 

 total length. The tail is considerably longer than the head and trnnk together, the 

 distance from the snont to the anns being in males 37,8— 42,3 "„, in females 36,5 — 

 41,7 "^o of the total length. The yonnghave 8 — 10 broad, dark cross-bands over the 

 bod)-; these bands in the adnlts either disappear entirel}- or dissolve into ring-sliaped 

 stripes and irregular spots; on the anterior corner of the dorsal fin is almost always a 

 black-brown patch, behind which there often is one or two more dark spots. Scales 

 begin to appear at a total length of ca. 60 mm.; at a length of ca. 100 mm. the tail and 

 the trnnk are completely covered by scales, as also the base of the unpaired fins. 

 Lateral line ventral. Pyloric appendages 2. The length reaches 520 mm.

Remarks on the S >■ u o n >■ m \-. 



In 1866 a Lycodes, taken in the Christiania Fjord, was described b}- M. Sars under the name L. gyacilis. It was a 

 very young specimen, only 43 mm. long, characterised by 10 saddle shaped cross-bands on a whiti.sh background. The species 

 was not rediscovered until in 1S8S, when Consen'ator Storm took 4 specimens, 97— 137 mm. long, in Trondhjem Fjord; a fifth, 

 very small individual was taken in the same fjord 6 years later. Lastly, during some of the practical fisheries investigations
