THE FISHES OF THE «INGOLF. EXPEDITIONS. 



21 



specimeus in the eastern part of the North Sea, at the stations enumerated below, belong to the said 

 species, which is carefully described and excellently figured in the Norwegian work cited here, I shall 

 limit myself to a few remarks. As characteristic for L. frigidus may be mentioned the uniform dark 

 or brownish colour and the uniform delicate squamation on the entire body to the occiput and the 

 branchial orifice and on the belly. Further the lateral-ventral side-line, starting from the upper end of 

 the branchial orifice, then arches downwards, running parallel with the lower margin of the tail in a 

 great extent. Young specimens (until no™™ length) are entirely naked, in the somewhat greater ones 

 the scales cover a smaller or larger part of the tail, and in the more mature state of the fish they 

 spread over the trunk and the belh'. 



The Ingolfiau specimens are from the following stations.

The largest specimen of the «North-Sea Expedition* has a length of little more than half a 

 meter; a specimen of a little larger size in the -Ingolf; -collection reminds so much of the L. rcticu- 

 Infus Gthr. (< Challenger Expeditions^ p. 77, pi. XIII), that I must regard them as absolutely identical. 

 The specimens of the < North-Sea Expedition* were from the seas around Beeren Island and Spitsbergen. 

 From the American expeditions of the « Albatross* a series of locaHties is indicated (,; Oceanic Ichthyo- 

 logy* 1. C). 



Lycodes Esmarkii (Coll., I.e. p. 84, pi. II, fig. 19— 21 and pi. Ill, fig. 22). 



A specimen, 260™" in length, from Station 138: North of the Faroe Islands (63^26' Lat. North, 

 7° 56' Long. West, depth 471 fathoms, temperature at the bottom -^ o=.6 C.) having 5 Hght bands over 

 the dorsal fin and the back and with both a medio-lateral and a ventro-lateral lateral Hne, agreeing 

 well with Colletts fig. 21, represents this type in the collections of <the Ingolf . Previously known 

 from the banks off Lofoten and from the north-west coast of Spitsbergen and from several points of 

 Fimnarken (260 — 459 fathoms).
