tion is also very similar: 7 saddle-shaped bands, bordered by a dark margin, break the light ground- 

 colour; between the foremost band and the dark-coloured neck there is a light eross-stripe. In addition, 

 a brown stripe is present on the head, extending from the snout under the eye on to the gill-covers; 

 further, there is a light oval spot but surrounded by a dark margin, behind the eye towards the upper 

 side. The pectorals count 20 — 21 rays; in one specimen there are 92 rays in the dorsal fin, 73 rays 

 in the anal.

Comparis o 11 w i t h Ly codes reticulatus. 

 The present form displays no slight resemblance to L. reticulatus Reinh. from West Greenland, 

 mainly in respect to colouration, as both in the older stages have the dark cross-bands transformed 

 to a more or less distinct network-formation; further, the} - have a mediolateral lateral line; nor do the 

 numbers of rays in the fins present any differentiating character. On the other hand, it seems as if 

 the variety macrocephahis was a form with relatively large head and large eye, which will appear 

 from the following comparison between two male specimens of almost equal size: 



Further comparison between almost equally large adult specimens is unfortunately not possible 

 for the time being, as L. reticulattis is not present in smaller nor var. macrocephalus in larger male 

 specimens than those given, and there is also a great gap in size between the females at hand. I 

 must provisionally suggest that the differences noted cannot be overlooked without further investi- 

 gation and that two varieties are to be reckoned with. 



If we bring < L. perspicillum Kr., the supposed voting of L. reticularis, into the comparison, 

 we see that the young of the latter have likewise a smaller head as well as a relativelv longer tail:

L. rossi Malmgr. (from Spitzbergen and the Kara Sea) is also near to the present form, but it 

 has a smaller head (length, 22,4—25,3% of the total length) and relatively small eyes (longitudinal 

 diameter, 3,6—4% of the total length). In addition, L. rossi has on the average fewer rays in the 

 pectorals, namely 117118 — 19(20), and the marking does not change over into the reticulate.
