bands (see fig. 5, Tab. X\'II of Liitkeii 1. c. 1886]; this specimen has 9 dark cross-bands (besides the 

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

 witli 10 cross-bands will be seen, whilst on the other hand, the number of bands in a specimen 114 mm. 

 long is reduced to 6. — In .specimens not qnite young the sharp boundar\- between the dark cross- 

 bands on the side of the body gradually disappear, dark colonr-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 the>- ma\- 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 frequentl)- divided in part or entirelx', into three Hght 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; 

 rareh- 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 nnn. (in the 205 nun. 

 female, taken the 26th of July 1901). 



Distribution. L. rossi is a high arctic fish, hitherto only fonnd in the Kara Sea, in Por- 

 sanger Fjord and at Spitzbergen. 



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

 in Treurenberg Kay, at 5 fathoms depth, and at Fosters Lslands in Hinlopen Straits, in eacli case a qnite 

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

 was 39 — 75 fathoms and bottom-temperatnre — 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., \\'. from C. Mitra (79'' 10' N. L. 11° E. L.) at 100 meters. Lastly, Dr. Joh 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 fonr specimens (65 — 223 nnn. 

 long) at 46 — 100 fathoms depth. 



Finalh', Dr. Hjort during the 1900 crnise 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-temperatnre — 1,2" C. 



Relation to allied Species. 



L. rossi stands verv close to the Greenland L. reticulahis Reinh.; it has however a more 

 slender form, and on the whole fewer rays in the pectoral fin (|i7| 18— 19I20I against |i9|2o|2i|), and 

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

 relation to L. reticulattis \ar. macrocephalus see p. 70. 



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