6. Artedidraco skottsbergi n. g. & sp. 



(PI. H fig. 7, n. IV fig. 15.) 



I specimen from stat. 6, S. of Snow Hill, depth 125 m., stones and gravel. 20th 

 of Jan. 1902. 



D. Ill, 25. A. 19. 



Head less depressed, profile contour of snout steeper, body still more com- 

 pressed than in A. minis. Depth of body nearly 5 times in total length without 

 caudal, length of head not quite 3 times. Interorbital width about 10 times in length 

 of head. Diameter of eye very little more than 3 times in length of head. Snout 

 a little shorter than eye. Lower jaw a little projecting. Distance from snout to 

 vent 126 % of distance from vent to snout. Depth of caudal peduncle contained 

 3'/3 times in length of head. Length of caudal fin 85 ?» of length of head. Pecto- 

 rals 1, 5 of length of head. Ventrals 65 % of length of head. First dorsal in the 

 onI\' preserved specimen rather narrow, half as long as head. * Barbel simple, 6' 3 

 times in length of head, not quite half as long as diameter of eye. 



Concerning the colour is stated on the label of the preserved specimen: "Whitish 

 with numerous dark spots on the sides and vertical fins." The distribution of these 

 spots is seen on fig. 15 PL IV. 



A second specimen of this interesting fish was caught at another opportunity 

 viz. at stat. 81 Bransfield Strait, depth 849 m., mud and some few stones, tempera- 

 ture at the bottom — 1,55' C. the 25th of Nov. 1902. Mr. SkoTTSBERG made a 

 sketch of this latter specimen, which was larger than the one described above. It 

 was of course preserved since it had been figured, but belonged to the zoological 

 treasures which were lost with the sinking vessel, "Antarctic". The sketch of this 

 fish was unfortunately not so elaborate as the others because Mr. SKOTT.SBERG was 

 in a great hurry when making it. It also looks disfigured because it is drawn as 

 if seen obliquely from above, but I have nevertheless deemed it to be worthy of re- 

 production for the sake of the colours, and to show that this species attains a greater 

 size than the only specimen preserved. 



Artedidraco skottsbergi is nearly related to A. minis, but is easily recognized 

 by its less depressed head with a steeper profile contour of the snout, greater depth 

 of caudal peduncle, shorter barbel, longer fins and different coloration. The difference 

 is perhaps more apparent at the first look than after comparison of measurements. 



The dimensions of the only specimen now in existence are: 



Total length without caudal 57 mm. 



Length of head .20 > 



• Probably comparatively shorter in adult specimens.
