network-marking is developed from the dark borders of the bands, especially on tlie 

 front portion of the body. The scaly covering in older individuals extends from a 

 little behind the root of the pectorals to the end of the tail or ceases somewhat in 

 front of this, but the belly and the anterior part of the back are naked; there are no 

 scales on the fins. The lateral line is mediolateral. Pyloric appendages 2. Size 

 245 mm. 



D. 91—96. A. 72 — 78. P. (19)20 — 21. 



Distribution. Northern East Greenland, ca. 50 — 150 fathoms; Jan Ma\en, ca. 

 40 — 100 fathoms. 



Of this form, which I ha\-e thought it best to consider as a \ariet\' of the foregoing species, 

 there is a number (14) of specimens, presenting a special interest as they show transition stages in 

 markings from the young with sharph" marked black cross-bands to a network formation in the adults 

 (cf. Tab. VIII), reminding one quite of that in L. reticulaUis. Por this reason Prof. Smitt (I.e.) lias 

 referred (the most of) these specimens to the West-Greenland species; I cannot but think however 

 that the differences are important, and I nnist for the time being hold them in part distinct. 

 Eleven specimens were taken at northern East Greenland by .Swedi.sh expeditions; two were taken at 

 Jan Ma3'en in 1900 b\' the steamer Michael Sars and kindh' handed over to me for examination 

 by Prof. Collett; one was likewise taken at Jan Mayen by Dr. Fischer and has been placed at my 

 disposal b\- Prof. F. Steindachner.

The form is moderately elongated, the height over the anus going 8—10 times in the total 

 length. The greatest thickness lies forward on the cheeks and is ca. I'/j times greater than the height 

 at the same place; the trunk is alread>- somewhat compressed, as its thickness a little in front of the 

 end of the pectoral goes about 1,4 times in the height, and the tail becomes gradually more and 

 more conrpressed. The anus lies almost at the middle of the bod\-, its distance from the snout being 

 46,2—50,6% of the total length. 



The length of the head is 26,2— 28,6°;o of the total length in males, 25— 26,2 °o in young 

 females and small specimens. Seen from the .side, its upper and lower margins each form a slighth' 

 curved line, seen from above the outline is somewhat oval. The top of the head is slightly arched. 

 The eyes are placed high up, so that their upper margins project forward over the forehead; their
