LYCODIN.'E. 



L. murcena sens, str., and have a greater distribution in relation to tlie total length of the fisli, than 

 in L. flagellicatida. 



The lateral line is double in both species, niediolateral and \-entral; the niediolateral branch 

 may sometimes be particular!}- distinct in L. mnrctiia (see fig. 15), but in L. flagellicaiida it is always 

 very indistinct, as even in the most favourable cases only single pores can be seen"). 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.miirce7ia 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 jjeritoneum shines through; the scales stand out lighter than the ground- 

 colour of the body. /.. flagellicaiida tends most often to be more gray-brown. 



In conclusion I ma\' gi\e the most important proportions of the three L. miircEua present:

Distribution. With the limitation here given to Lyceiiclielys umrtviia Coll., the species is only 

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

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

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

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

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

') Such is the case at anj' rate in my present specimens. Fig. 31 in the Fishes of the Xorth-Atlantic Kxpedition 

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