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

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

 markings from the }-oung with sharply marked black cros.s-bands to a network formation in the adults 

 (cf. Tab. VIII), reminding one quite of that in L. reh'ciilatus. For this reason Prof. S mitt (I.e.) has 

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

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

 Ele\en specimens were taken at northern East Greenland b\- Swedish expeditions; two were taken at 

 Jan I\Iayen in 1900 b\- the .steamer Michael Sars and kindly handed over to me for examination 

 by Prof. Collet t; one was likewi.se taken at Jan May en by Dr. F'ischer and has been placed at my 

 disposal by Prof. F. S t e i n d a c h n e r. 



Description. 

 The most important proportions of all 14 sijecimens are as follows: 



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. 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 gradualh' more and 

 more compressed. The anus lies ahnost at the middle of the body, its distance from the snout being 

 46,2 —50,6 "/,> of the total length. 



The length of the head is 26,2-28,600 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 slighth- 

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

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