(Pl. IV fig. 13.) 
2 specimens from stat. 53, Port Williams, Falklands, depth 12 m., sand and 
gravel. 3d of Sept. 1902. 
3 specimens from stat. 54, Port Stanley, Falklands, depth 10 m., mud and shells. 
3d of Sept. 1902. 
D. VI, 28 — 30. A. 28 — 29. Sq. about 46. 
Head broad, rather strongly depressed, its width being 3 / 4 of its length, the latter 
contained about y / 3 times in total length without caudal. Anterior portion of body 
depressed, posterior compressed, its depth about 5 to 5 1 /* times in total length 
without caudal. Diameter of eye a little more than 4 times in length of head in 
adult specimens, only 3V3 times in small specimens. Snout broad, rounded, equal 
to diameter of eye in young specimens, a little longer in the adult. Interorbital 
width 67 z to 7 times in length of head. Maxillary extending to below anterior 
third or fourth of eye. Lower jaw not projecting. Scales on body rather large, 
ctenoid, on head smaller and weaker, but covering opercles, occipital region and 
posterior part of interorbital space (in young specimens the scales of the head are 
still less developed). Lower side of head, preorbital and snout to behind nostrils 
and anterior part of interorbital space naked. Second dorsal rather high, its longest 
rays about z / 3 of length of head. Pectorals rounded about 3 / 4 length of head, 
ventrals a little shorter reaching to vent or beyond. Pectorals reaching to about 
fourth anal ray. Caudal strongly rounded. Fins to great extent black, especially vent- 
rals, but also anal in all specimens quite black. Dorsal and caudal sooty with light 
margin and the latter also with small light round spots (in spirit). Caudal peduncle 
much deeper than long, its depth being contained about 3 times in length of head. 
This fish appears to be related to Notothenia marionensis GÜNTHER, but the 
scales of the head are by far not so strongly developed in the former as in the 
latter, at least if the South Georgia race of it is similar to the typical one from 
Marion Island. The interorbital space of N. marionensis is much narrower and its 
ventrals shorter not reaching the vent. Its head is narrower being about z / 3 of its 
length and the snout is more pointed. The intensely black fins of the new species 
seem also to present a very good characteristic. The race of N marionensis from 
South Georgia has a much more slender caudal peduncle which is longer than deep 
and with its depth less than a fourth of the length of head. The same fish has also 
the caudal less strongly rounded than this new species. 
Notothenia sima which has a similar number of fin rays and scales as N. karl- 
andreæ differs from the same in having a less depressed and narrower head with
