bands (see fig. 5, Tab. XVII of Ltitken 1. c. 1886); this specimen has 9 dark cross-bands (besides the 

 dark spot on the point of the tail), but it does not stand alone, as in my fig. 1 e, Tab. VII a specimen 

 with if) cross-bands will be seen, whilst on the other hand, the number of bands in a specimen 114mm. 

 long is reduced to b. — In specimens not quite young the sharp boundary between the dark cross- 

 bands on the side of the body gradually disappear, dark colour-material being here deposited ; the light 

 interspaces between the bands then assume the form of saddle-shaped markings, which extend from 

 the free edge of the dorsal fin down towards the lateral line, but they may be traced especially on 

 the posterior part of the tail right across the body (cf. the two largest figures on Tab. VII). - The 

 light dark-margined band, which extends across the neck and down on to the free fold of the gill- 

 cover, is frequeutlv divided in part or entirely, into three light spots b\ a dark longitudinal streak on 

 each side, sometimes even into four spots by another dark streak on the middle line of the neck; 

 rarely it is represented only by a light spot on and over the gill-cover. 



In all the 3 females the eggs are small, at the most with a diameter of 1,5 mm. (in the 205111111. 

 female, taken the 26th of July 1901). 



Distribution. /.. rossi is a high arctic fish, hitherto only found in the Kara Sea, in I'or- 

 sanger Fjord and at Spitzbergen. 



At .Spitzbergen, it has been taken at several places. First by a Swedish expedition of 1861 

 in Treurenberg Bay, at 5 fathoms depth, and at Fosters Islands in Hinlopen .Straits, in each case a quite 

 small specimen; next, by the Russian expeditions of 1899 and 1900 in the Stor Fjord, where the depth 

 was 39 — 75 fathoms and bottom-temperature -- 0,7 to — 1,6 C, a small specimen at each place. The 

 Kolthoff Expedition of 1900 took one specimen 163 mm. long in Ise Fjord (Coal Bay) at 100 meters 

 depth, and another of 87 mm., \Y. from C. Mitra (79" 10' X. L. n'E, L.) at 100 meters. Lastly, Dr. J o h an 

 Hjort in 1901 took a number of specimens (54,5—205 mm. long) in Green Harbour (an arm of Ise 

 Fjord), where the depth was 75 fathoms. 



In the Kara .Sea the Dijmphna Expedition of 1882—83 obtained four specimens (65 — 223111111. 

 long) at 46—100 fathoms depth. 



Finally, Dr. Hjort during the 1900 cruise of the Michael Sars , obtained it in one of the 

 fjords of East Finmark, namely in the innermost part of the Porsanger Fjord (the so-called 0stpol) 

 where the depth was 30—50 fathoms and the bottom-temperature — 1,2 C. 



Relation to allied Species. 



L. rossi stands very close to the Greenland L. reticulatus Reinh.; it has however a more 

 slender form, and on the whole fewer rays in the pectoral fin (J17J 18— 19I20] against 1 19I ao |2i | ), and 

 its colouration does not change over with age into the network-formation (reticulate I. Concerning its 

 relation to L. reticulatus var. macrocephalus see p. 70. 



L. lutkenii Coll. is also a closely allied form (cf. p. 61).
