THE FISHEvS OF THE aNFOLF:> EXFEDITIONS. 



Lycodes muraena Coll. 



A specimen io3/^ inches long (275"'™) was obtained in the Davis Strait between Godthaab and 

 Sukkertoppen, at Station 27: 64- 54' Lat. N., 55= 10' Long. W., at a depth of 393 fathoms (a temperature 

 of 3°. 8 C. at the bottom, which consisted of a soft gray clay with numerous pebbles, mostly granite). It 

 agrees substantially with the figure and description of Collett ( Den norske Nordhavsexpedition», Fiskene, 

 p. 116, pi. IV, fig. 29 — 31; compare also F. Smitt: < Skandinaviens Fiskar p. 618 and Giinther's 

 «Deep-Sea Fishes: Challenger Expedition > S. 79, tab. 12, fig. A). The species has been taken in several 

 instances by the said Norwegian expedition at the banks off Helgeland, Beeren-Island and Spitsbergen 

 (Norsk-0erne) on depths of 350 — 658 fathoms, the bottom brown, green or bluish-gray clay, the bottom 

 temperature being -^ o'.g a -f- i\2 C. L. inn r ana is further taken by an English expedition in the 

 fi Faroe-channel » at 540 — 608 fathoms. In 1896 Ingolf? obtained further 12 younger specimens at the 

 following stations: 



The larger specimen from Stat. 27, the only squamate, has larger eyes than the smaller and \-ounger 

 ones, apparently also a less flatfish liead and a shorter snout. It is therefore not quite certain that it 

 is identical as species with these. The size of the younger specimens lies between 203'"'" and 108™™. 

 Of the scales nothing is seen in these smaller .specimens. In the larger of them the length of the head 

 is scarcely '/s of that of the whole body (trunk and tail), in the smaller ones it varies between i -^6.5 

 and I -4-8.1. With 2 exceptions (Stat. 27 and 65, where the bottom temperature was + 3'.8 and +3') 

 all these specimens were from stations with a bottom temperature below zero. 



Of allied species with a similar longish eel-like shape some other species are described i) L. 

 Verrillii G. & B., 2) L. paxilliis G. & B. (into which L. paxilloidcs' is afterwards drawn as a synonym), 

 for these species may be consulted the ;■ Oceanic Ichth}'ology p. 309 — 11 and 527, fig. 277, 279, 280 and 

 282. Further 3) L. (Lycodomis) iniyabilis Goode &. Bean (Giiuther: Deep-Sea Fishes, Challenger 

 Report etc. p. 81); 4) L. (LycodopJiis) alhiis Vaill. («Expeditions scientifiques du Travailleur p. 309, 

 pi. 26, fig. I), caught at a depth of 3975 metres on the way between the Azores and France, and 5) L. 

 (Lysoichelys) porifer Gilb. (Proceed. Un. St. Nat. Mus. XIII (1890), p. 104), from South California at a 

 depth of 857 fathoms.
