It is also stated that a number of L. pallidus were obtained by 

 the Danish Ingolf-Expedition in July and August 1896, from several places 

 north of the Faroe Islands, about Iceland, and south of Jan Mayen 

 Island'. 



The specimens, the largest of which was of a total length of 

 245 mm., were caught at considerable depths, or between 293 and 

 957 fathoms, and from icy cold water (bottom temperature down to 

 — 1.1° Celsius). 



No special description has as yet appeared concerning these spe- 

 cimens. 



4. L. zoarchus, Goode & Bean. In 1895, a couple of specimens 

 of a Lycodes were described under tliis name which were obtained by 

 the «Albatross Expedition» (of late years) from a depth of 130 to 190 

 fathoms, off Nova Scotia. The largest of these individuals was of a 

 total length of 366 mm. 



It appears from the detailed descriptions, given by the above 

 named authors, and the accompanying illustrations, that L. zoarchus does 

 not appear to differ in any important point from the Scandinavian 

 L. gracilis. 



Diagnosis. 



Body tolerably elongated; the height is contained (above the anus) 

 9.5 to 10.5 times in the total length. 



In the males the head is contained about 4.5, and in the females 

 about 5 times in the total length. 



The tail is longer than the head and body together. The body 

 proper is contained about 2.5 times in the total length. 



Colouration changes with age. Young ones have 8 to 10 broad, 

 dark, and closely situated cross bands down the body. 



These bands disappear completely, as a rule, in adults; the ground 

 colour is light greyish brown with irregular patches which can form 

 annular stripes along the body, or the body is of one uniform dark 

 greyish brown colour throughout. 



Most (light and uniformly coloured) specimens have a row of dark 

 greyish brown spots running along the median line of the body.
