LYCODIN.E. 



Z. inurcena sens, str., and have a greater distribution in relation to the total length of the fish, than 

 in L. flagellicauda. 



The lateral line is double in both species, mediolateral and ventral; the mediolateral branch 

 may sometimes be particnlarly distinct in L. jiiurceiia (see fig. 15), bnt in L. flagellicauda it is always 

 verv indistinct, as even in the most favonrable cases only single pores can be seen'). For the rest, the 

 \entral branch in Ijoth species may be rather difficnlt to follow, or not at all traced, beyond the anns. 



The colonr in both sj^ecies is nniforni, withont bands or spots. L. mjcrtena is brownish above, 

 below the median line yellowish; the anal fin and pectorals are grayish-white, the dorsal fin dark- 

 gray; on the belly, the black peritonenm shines through; the scales stand out lighter than the gronnd- 

 colonr of the bod\'. L. flagellicauda tends most often to be more gra\-bro\vn. 



In conclusion I niav give the most important proportions of the three L. miircena present: 



Distribution. With the limitation here given to Lycenclielys murcvna Coll., the .species is only 

 known from 3 .specimens. The first of these (140 mm. long) was taken b)- the Norwegian North-Atlantic 

 Expedition in June 1877 off Helgeland in Norway, 325 kilom. W.S.W. from Bodo (66" 41' N.L. 6° 59' E.L.), 

 where the depth was 350 fathoms and temperature of the bottom — o°9 C. The second specimen (145 nun. 

 long) was caught in July 1900 by the .steamer cMichael .Sars E. from Iceland (64° 53' N.L. 10° W.L.) 

 where the depth was 340 fathoms and bottom-temperature — o°69 C. Lastly, the third specimen (181 mm. 

 long) was taken in 1902, likewise by the Michael Sars , in the Fferoe Channel (60° 19' N.L. 5"'39' W.L.), 

 where the depth was 620 fathoms and bottom-temperature under o" C.

1) Such is the case at any rate in my present specimen.s. Fig. 31 in the Fi,she.s of the North-Atlantic Expedition 

 shows however, a whole row of pores along the linear median furrow of the side; such a condition 1 have not seen.
