(Schwed. Südpolar-Exp. 
6. Artedidraco skottsbergi n. g. & sp. 
(PL II fig. 7, PI. 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 tirrjes. 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 
3V3 times in length of head. Length of caudal fin 85 / of length of head. Pecto- 
rals V 5 of length of head. Ventrals 65 % of length of head. First dorsal in the 
only preserved specimen rather narrow, half as long as head. * Barbel simple, 6 2 / 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 PI. 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 — i, 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. SKOTTSBERG 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.
