Systematic Part. 



Fam. Zoarcidce Swainson (1839). 

 Subfam. Lycodince Jordan & Evermann (1898). 



Body elongated, zoarciform or angnilliform, covered to a more or less extent 

 by small round, non-imbricate scales, which are sometimes wanting. Lateral line 

 ventral, mediolateral or double, often less distinct. Fin-rays soft and jointed; the 

 unpaired fins are continuous, and the dorsal fin has no depressed portion; pectoral 

 fins well-developed; ventral fins present, with few short rays, jugular in rjosition. 

 Gill-membrane firmly united below to the throat. Teeth on the mandible and inter- 

 maxillary, often also on the vomer and palatal bones. Pseudobranehiae present; no 

 swimbladder; pyloric appendages rudimentary (2) or absent. 



Key to the determination of the European and Greenland genera of Lycodinae.

l ) By Polar Depths I understand the deep waters which are bounded to the south, not by the polar circle, but by 

 tlie submarine ridge between Greenland-Iceland-Fseroe Isles-Shetland; because north of this ridge, polar water with a tempera- 

 ture under o° C. (the • cold areas) is constanUy found at the bottom where this lies more than c. 300 fathoms under the surface.
