The height over the anus amounts in general to 8 — 11% of the total lensrth. 



o a O 



The length of the head in the males is 19,6 — 23,8",,, in the females 18,8 — 21,4% of the 

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

 distance from the- snout to the anus being in males 37,8—42,3",,, in females 36,5 — 

 41,7 % of the total length. The yonng have 8 — 10 broad, dark cross-bands over the 

 body; these bauds in the adults either disappear entirely or dissolve into ring-shaped 

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

 black-brown patch, behind which there often i s o ne or two more dark spots. .Seal e s 

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

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

Remarks on the Synonymy. 



In 1S66 a Lycodes, taken in the Christiania Fjord, was described by M. Sars undei the name L. gracilis. It was a 

 very young specimen, only 43 mm. long, characterised 1>v to saddle shaped cross-bands on a whitish background. The species 

 was not rediscovered until in 1888, when Conservator Storm took 4 specimens, 97 — 137111111. long, in Trondhjein Fjord; a fifth. 

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