The specimens from East Greenland and Jan Mayen all show a livelier colouration, as is seen in 

 Fig. i b, c, d, e of Tab. IX and Fig-. 13 & 14 in the text. They have distinctly 2 dark bands on the 

 trnnk and 5 — 7 on the tail; in addition, the end of the tail (fin) is dark-coloured ; the dark bands are 

 especially distinct on the dorsal fin and the upper part of the body, lower down they may disappear in 

 the general darkish ground-colour, lint they are often also, especially on the tail posteriorly, separated 

 by light interspaces right across, the light may even separate the bands forward on the body and 

 constitute an important part of the colouration. The dark bands are light in the centre, often so light 

 that the margins show as a distinct, dark-brown frame, or that an originally single band dissolves 

 into two; sometimes the light in the band is partly limited to a rounded-off spot (see Fig. 1 e of Tab. IX'. 

 Right across the neck, from gill-cover to gill-cover stretches a light, dark-bordered stripe, which some- 

 times however can be limited to a rounded-off light spot on the centre of the neck or very rarelv 

 may disappear almost entirely. 



As alreadv mentioned, I am much inclined to refer Nr. 24 and Xr. 25 among Lit tk en's /.. 

 reticulatus (I.e. p. 332) to L. seminudus. Full certainty cannot be attained as the specimens are now 

 skeletons, but the considerable length of the head (28,5 — 29,5% of the total length), the rich provision 

 of teeth (on the intermaxillary 17 —18 teeth in a row, 5 — 7 on the vomer and 20 in a row on the mandible), 

 as also the shortness of the pectorals (10% of the total length) seem to point certainly in this direction. 

 The number of the vertebrae is 95 — 96 (23 — 24 + 72). 



I Later addition. During my participation in the summer cruise of the Michael Sars in 

 1902, a specimen of L. seminudus was taken on the 26th of June at 62° 58' X.L. 1 56' F.L, and at c. 

 600 fathoms; the place lies in the cold area off western Norway. 



It is a S with all the known characters of the species; its most important proportions are 

 as follows: 



Total length 268 mm. 



Length of the head 73 



Distance from snout to anus 128 



Height over the anus 28 — 



In proportions of the total length, the length of the head is therefore 27,2%, the distance 

 between the snout and the anus 47,8%, the height over the anus 10,4%; of the same length the 

 distance between the snout and the anterior end of the dorsal fin is 32,1%, the length of the pectoral 

 10,6%; the latter fin contains 21 22 rays. 



The scab' covering reaches from the end of the tail forward to a point, which lies an e\ e's 

 length behind the point of the pectoral, being wedge-shaped in front; the scales extend out oil to the 

 basis of the posterior part of the dorsal fin. The body is without markings. 



Further, our Museum has recently received through Mr. H. Kraul, director of the Upernivik 

 colony in West Greenland, 4 very large /.. seminudus (400— 497 mm. long), all males, which are 

 remarkable for their relatively large head (its length being 27,6 — 30" ,, of the total length). The pectorals, 

 which count (19) 20 rays, amount in length to n, 1 — 11,8",, of the total length. The scab wedge in 

 one specimen extends forward slightly in front of the vertical line through the anterior end oi the
