LVCODIX.E. 2L 



Its dimensions are as follows: 



Total length i 9 2 mm. 



Length of the head 30 



Distance between snont and amis n% — 



Height over the anus i - — 



The length of the head is thus 20,3°',;, of the total length and falls therefore within the limits 

 of variation occurring in the adult specimens from Finmark; thus, the measurements given by 

 Prof. Collett, reckoned in percentages, show the length of the head as 19,2 24 , of the total length 

 (in 10 males 22,2— 24%, in 12 females 19,2— 21,9%). Again, the head and trunk together (or distance 

 between snout and anus) is 38",, of the total length, which figure is very close to that of the adult 

 individuals, where (in 4 specimens) it is 38,3 — 42,9 "',, '). 



It is the colouration however which makes one think at once of L.esuiarkii. The ground- 

 colour is dusky brown above, yellowish white below; the scales are whitish and show as light points 

 against the dark background. ( hi the brown ground-colour the body is marked by 7 whitish yellow 

 bands which are distributed wide apart with exception of the last. The foremost of these bands 

 extends from the gill-cover over the edge on to the middle line of the neck; the band on the one 

 side does not reach so high up and does not therefore meet with that on the other side. The second 

 band lies almost over the end of the pectorals; it begins at the upper margin of the dorsal fin and 

 divides like a horse-shoe a little below the Hue of the back. The third band, which lies somewhat 

 behind the anus, is similarly branched but more angularly; the fourth and fifth bands have also 

 more or less the distinct form of a A- The sixth band as also the seventh, which lies near to the 

 sixth, just at the end of the tail, extends across the tail and out to the borders of the fins in the form 

 of forward projecting arches. — If one compares this with Collett's figure of an adult L.esmarkii 

 (1. c. PI. Ill, fig. 22) one sees that the colouration of the latter is only a further development of that in 

 the present young specimen, as the bands by much branching have assumed the form of festoons. 



The pectoral fins have 22 rays, which number agrees with that of the adults from Finmark; 

 in five of these I have counted 22 — 23 rays, the above mentioned specimen of 443111111. has 23 rays 2 ). 

 The lower rays are gradually .shortened so that the posterior margin of the fin is evenly rounded as 

 in the adults. The dorsal fin has 117 rays, the anal 102, which numbers also fall within the variations 

 found in the adult specimens from Finmark, viz. [13— 118 rays for the dorsal, 97—102 for the anal, 

 according to Collett. 



The scaly covering extends forward to the light band on the neck, to the base of the 

 pectorals and ventrals, also some way on to the unpaired fins, especially the dorsal fin, hut the fore- 

 most part of the anal fin on the other hand is naked. The scales have therefore almost reached til 

 complete distribution. 



M As it might be of interest to have the measurements of the specimen ca. 443 111111. mentioned above, the smallest 

 hitherto obtained from Finmark, I give them here: distance between snout and anus [75 mm. (39,5 ofth< total li igth 

 of the head 90mm. (20,30/0 of the total length), height over the amis 54,5mm. (12,3 ' , of the total length). The specimen is 

 badly preserved and the colour has almost entirely disappeared, the internal organs have been removed s,, that the sex cannot be 

 determined. 



-1 When Collett gives 20—23 ra\s. it must he remembered, that tin lower number has arisen through including 

 under L. esmarkii the specimens with smaller number of fin-rays (— L. eudipleurosticlus) from the Norwegian N.ith Atlantic 

 Expedition.
