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

 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 arc no 

 scales 011 the fins. The lateral line is m ediola t eral. Pyloric appendages _'. Size

Distri but i i)ii. Northern East Greenland, ca. 50 — 150 fathoms; fan May en, ca. 

 40 — 100 fathoms. 



Of this form, which I have thought it best to consider as a variety 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 sharply marked black cross-bands to a network formation in the adults 

 (cf. Tab. VIII), reminding one quite of that in L. reticulatus. For this reason Prof. Smitt (I.e.) has 

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

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

 Eleven specimens were taken at northern East Greenland by Swedish expeditions; two were taken at 

 Jan Mayen in 1900 by the steamer Michael Sars and kindly 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 by 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 011 the cheeks and is ca. 1' . times greater than the height 

 at the same place; the trunk is already 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 compressed. 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 bead is 26,2—28,6",, of the total length in males, 25 26,2% in young 

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

 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
