LYCODIN^. 



tioii is also very similar: 7 saddle-shaped bands, bordered b>- a dark margin, break the light ground- 

 coloitr; between the foremost band and the dark-colonred neck there is a light cross-stripe. In addition, 

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

 further, there is a light oval spot bnt surrounded by a dark margin, behind the ej-e 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. 



One of these specimens is represented in fig. i a on Tab. \'III. 



Comparison with Ly codes reticulatus. 

 The present form displa)-s no slight resemblance to L. reticulatiis 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; furtlier, 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 macrocephaliis was a form with relativeh- large head and large e>'e, which will appear 

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

Further comparison between almost equalh- large adult specimens is unfortunateh not possible 

 for the time being, as L. reticHlatiis is not present in smaller nor var. macrocephaliis 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 \\ith. 



If we bring «Z. perspicillum Kr., the supposed young of L. reticulatus, 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"/o of the total length). In addition, L. rossi has on the average fewer rays in the 

 pectorals, namely (17)18 — 19(20), and the marking does not change over into the reticulate.
