orlesspronounced reticular pattern is developed 

 through the dark edges of the bands, especially on 

 the front part of the body. The scales in older 

 specimens are reaching from a little way behind 

 the base of the pectoral fins to the end of the 

 tail, or they stop a little in front of the latter, the 

 belly and fore part of the back being however 

 naked; no scales on the fins. Lateral line medio- 

 lateral. App. pyloricæ 2. Size: 245 mm. 



R. br. 6; D. 91—96; A. 72 — 78; P. (19) 20 — 21. 



One single specimen of this new variety was for the first 

 time caught by the Nathorst- expedition 1899, in Franz Joseph 

 Fjord, at a depth of 100 — 110 metres. In 1900, 6 specimens 

 were caught by the Kolthoff- expedition at 72° 25' lat. N. 

 17° 56' long. W. at a depth of 300 metres, 3 specimens were 

 caught at 73° 55' lat. N. 19° 20' long. W. at a depth of 150 metres, 

 and 1 specimen at 74° 35' lat. N. 18° 15' long. W. (SE. of Pen- 

 dulum Ö), where the depth was 150 metres. The size of these 

 11 specimens is 61 — 245 mm. 



This variety has a great resemblance to L. reticulatus Reinh. 



from West-Greenland, especially with regard to colour pattern 



as both of them when they grow older have the dark transverse 



bands transformed into a more or less pronounced reticular 



pattern ; moreover they both have a mediolateral lateral line ; 



nor can they be distinguished by the numbers of rays in the 



fins. On the other hand the var. macrocephalus seems to be 



a comparatively large-headed and large-eyed fish, which will be 



seen by the following comparison between two male specimens 



of about equal size:
