1 specimen from stat. 20, Antarctic Bay (just outside the glacier), South Geor- 
gia, depth 250 m., small stones. 6th of May 1902. 
2 specimens from stat. 22, Cumberland Bay, South Georgia, depth 75 m., clay 
and some algæ, temperature + i, 5 ° C. 12th of May 1902. 
i specimen from stat. 33, Boiler Harbour, Cumberland Bay, South Georgia, 
depth 22 m., clay and algæ. 30th of May 1902. 
D. Ill, 23 — 24. A. 17. 
Head broad, depressed, body compressed. Depth of body (at ventrals) not 
quite 4 times in total length without caudal in adult specimens, 4V4 times in young. 
Length of head about 2 3 / 5 to 2 2 / 3 times in total length without caudal. Interorbital 
width 8 to 8V4 times, in adult 7 1 /* to 8 times in length of head. Diameter of eye 
nearly 4 times in adult, 372 to 3V3 times in young, in length of head. Snout and 
eye subequal in adult, the former a little shorter in young. Lower jaw a little pro- 
jecting, more in young than in adult. Distance from snout to vent s / 4 (125 — 130$) 
of distance from vent to root of caudal fin. Depth of caudal peduncle contained 
about 4 times in length of head. Length of caudal fin about a / 3 of length of head 
in adult, nearly s /<5 of the same in young. Pectoral rounded about 2 / 3 of length of 
head. Ventrals a little less than 7 2 length of head in adult male, a little more than 
V 2 length of head in adult female, 3 /s of the same in young male, a little more than 
that in young female. First dorsal very narrow, in young specimens r / 4 (q 71 ) or 
Vs (?) of total length without caudal, in adult broader and shorter, y? (<V) to hardly 
more than I /s (?) of total length without caudal, in the last case hardly more than 
reaching second dorsal, in the first overlapping the same widely. 
Barbel simple and bluntly pointed in females, not much more than V 4 of length 
of head; with a club-shaped end covered with small papillæ and equal to I / 3 of 
length of head in males. The barbel is subequal to or usually longer than diameter 
of eye.
