/.. murcena 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 particularly distinct in L, murcena (see fig. 15), but in L. flagellicauda it is always 



very indistinct, as even in the most favourable cases only single pores can be seen 1 ). For the rest, the 

 ventral branch in both species may be rather difficult to follow, or not at all traced, beyond the anus. 



The colour in both species is uniform, without bands or spots. L.murama is brownish above, 

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

 grav; on the belly, the black peritoneum shines through; the scales stand out lighter than the ground- 

 colour of the bod}'. L. flagellicauda tends most often to be more gray-brown. 



In conclusion I may give the most important proportions of the three L. mur&na present:

Height over the anus

Distribution. With the limitation here given to Lycenchelys murama Coll., the species is only 

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

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

 where the depth was 350 fathoms and temperature of the bottom — o c o. C. The second specimen (145 mm. 

 lung) was caught in July 1900 by the steamer Michael Sars E. from Iceland (64° 53' N.L. io° 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 Faeroe Channel (6cr 19' N.L. 5 39' W.L), 

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

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