Tilstedeværelsen af en Sidelinie synes ikke at være 

 omtalt i noget af de ovenfor anførte Skrifter, og Kroyer 

 nævner udtrykkelig, at den mangler. En Sidelinie er ikke- 

 destomindre tilstede, og Porerne ere overalt tydelige, om 

 end ikke særdeles store'. Den udspringer ved Gjællespal-

 funden ved Island (Fische Isl. p. 54, 1829); ved Spitsber- 

 gen er den ligeledes. som det synes, hyppig, og er her 

 funden af Kroyer allerede i 1838. og senere af idle de 

 efterfolgende Expeditioner i disse Farvaude. Den er liidtil 

 ikke fundet veil det europæiske Continent, men forekonnuer 

 sandsynligvis ogsaa her paa passende Dybder af Ishavet.

Descriptive Observations. — The total length of 

 file individual taken on the Expedition was 79™"'; length 

 of head 25'""'. The cuneiform osseous tubercles are so 

 closely disposed over the body that their basal lines, in 

 tlie lateral region, are as a rule contiguous; on the tail, 

 these tubercles are all considerably smaller. The 5 tii'st 

 rays in the first dorsal are furnished on either side towards 

 the point with a small granulated spine. Moreover, the 

 base of the pectorals, exteriorly, is invested with .a teg- 

 ument similar to that covering the head and the body. 



Number of fin-rays: — 1 D. 7; 2 D. 12; A. 12; 

 P. 23; C. 10. 



The occurrence of a lateral line does not appear to 

 have been observed by any of the naturalists whose works 

 are cited above; nay. Kroyer emphatically declares it to 

 be wanting. A lateral line nevertheless there is. and the 

 pores, though not particularly large, are distinctly percep- 

 tible.' It commences at the upper extremity of the branch- 

 ial opening, extending fi-om thence nearly straight till 

 a little below the 2nd dorsal, where it suddenly bends down- 

 wards, striking (iir obliquely to the mesial lint", which it meets 

 at a i)oiut distant aliout half the length of the head from 

 the origin of the tail, and then passing straight to the 

 caudal. Number of jiores 13 — 14.

 depth of from 60 to 20U fathoms (or still deeper), and is 

 one of the fishes whose range extends furthest north. (3u 

 the coast of Greenland, where it is common, it was observed 

 as far hack as the last century, hv Miiller and Fabricius, having 

 been latest met with on the English North Pole Expedition, 

 1875. in divers localities on the western shores of Green- 

 land, as far north as 79" and 80". According to Faber. 

 (Fische Isl. p. 54, 1829) it inhabits the coast of Iceland; 

 off Spitzbergen it is likewise said to be numerous, having 

 been observed in those regions by Kroyer, in 1838. and 

 since • then on all subsequent Arctic Expeditions. Up to 

 the present time it has not been met with oft' the con- 

 tinent of Euro])e, but occurs probably here too at the 

 right depth. VycJopferus orhis, from Bering's Straits, being, 

 as before observed, hardly entitled to rank as a sjjecies 

 distinct from E. sphiosus, it is perhaps circumpolar in its 

 ranse. 



' Probably it is more or less obliterated in specimens preserved 

 for any length of time in spirits, but will again become obWous if 

 the skin be sufficiently moistened with water.
