LYCODIN.^. 



1900 in the mouth of the Ise Fjord at a depth of 350 meters, the other two by the Michael Sars» in 



1901 in the Ise Fjord at a depth of 260 meters. The most important measurements of these individuals 

 are as follows:

Tlie largest of the individuals is remarkable for its great breadth of head just behind the 

 eyes; it is a male and the same characteristic has already been noted for this sex in another species 

 {L.vahlii, cf. p. 20 with fig. i & 2); further, the snout in this individual extends unusually far forward 

 in front of the underjaw. The pectorals contain 18, 18 and 19 rays. The distance of the dorsal fin 

 from the snout is 28,2 — 31,2% of the total length. On the side of the body the scales extend forward 

 to a little behind the root of the pectorals, but both the anterior portion of the back and the belly on the 

 other hand are free from scales, even in the largest of the specimens. The 207 mm. long specimen is 

 wanting in cross-bands, uniformly grajish brown, lighter underneath especially on the underside of 

 the head forward; the anal fin darkish, the front part lighter and with a light border. The colour 

 in the 147 mm. long specimen is very dark, rusty brown, with extremely faint indications of cross- 

 bands; the belly and fins are of a dark mouse-gray, the anal darker posteriorly, the underside of the 

 head lighter in parts. In the one 117 mm. long, the colour is likewise very dark except on the fore- 

 most part of the imderside of the head, with very indistinct bands, which are however, very apparent 

 on the dorsal fin, especially towards the margin, to the number of 7 with a dark spot on the point 

 of the tail; the anal fin blackish, especially posteriorly, forward lighter on the lower margin. The 

 ventral lateral line is distinct, also the mediolateral in parts, yet only in the smallest individual. 



Lycodes pallidus from East-Greenland. 



In the Stockholm's , Riks-Museura '^ I have seen not less than 53 specimens, taken at the 

 northerly East-Greenland by the Nathorst-Kolthoff Expeditions of 1899 and 1900. A large number 

 of these specimens have been described by F. A. Smitt (I.e.) under the names: L. vahlii forma pallida^ 

 L. vahlii f. typica and L. retiailatits f. frigida. 



]\Iost of the specimens are under 100 mm. in length, only 18 are above that from 105 — 178 mm. 

 In 33 of these (55,5 — 178 mm.) the length of the head is 20,7 — 25,3%, the distance between the snout 

 and the anus 38-44,4' „, the height over the anus 8—10,3%'), '^he longitudinal diameter of the eye 

 (in individuals of 125 mm. and over) 3,4—4,5% of the total length. The pectoral fins contain 18—19, 

 more rarely 20 rays. A young specimen of 55,5 ram. is still naked, but scales have begun to appear 

 in another of 65 mm. In specimens of total length 70-125 mm., the scaly covering extends forward 



■) In one case ii,i°/o, in young specimens sometimes as low as 7,3 °'o.
