With BOULENGER 1 * I feel convinced that FiSCHER’s Notothenia angustifrons a 
ought to be referred to GüNTHER’s N. marionensis 3 in such a way that both belong 
to the same species. I am, however, uncertain whether there is a subspecific dif- 
ference between the fishes from Marion Island and South Georgia, or not. The for- 
mula for the vertical fins of GüNTHER’s small specimen is given as “D 7/29, A. 25.” 3 
FISCHER records: “D. 6 — 29; A. 30.” In the present specimens I have counted in 
most cases d. VI, 30 (31), a. 30. There is thus a difference in the number of anal 
rays. The interorbital width is also, as it seems, narrower in the fish from South 
Georgia, and contained about 10 times in the length of head. The snout is also 
longer than eye in the adult, but not in the young. 
As GÜNTHER only had a single specimen it is, however, best to leave the ques- 
tion about the subspecific difference, alluded to above, open as yet. Should such a 
difference be proved, the name of the fish from South Georgia will be Notothenia 
marionensis angustifrons . 
The general shape, the strongly ctenoid, rather large scales, and their distribu- 
tion on the head and body etc. make this species easily recognizable. 
The largest specimen in this collection measures 120 mm. without caudal. 
4. Notothenia dubia n. sp. 
(PL III fig. 9.) 
3 specimens caught in a net sunk to a depth of 20 m. in Boiler Harbour, 
Cumberland Bay, South Georgia. 30th of May 1902. 
Among the collections from South Georgia, Boiler Harbour were three small 
specimens of a Notothenia which I cannot refer to any of the known species. They 
may therefore be described here under the above given provisional name. 
Depth of body about 5 times in total length without caudal. Length of head 
about 3 I L to 3 3 / 5 times in total length. Diameter of eye about 4 times in length 
of head. Interorbital width about b'/z times in length of head. Head and body 
compressed, upper and lower contour-lines almost similar. Snout shorter than dia- 
meter of eye or at most in the smallest specimen equal to the same. Mouth a little 
oblique, lower jaw projecting a little beyond upper, maxillary reaching to below 
anterior fourth of eye. Opercular and occipital regions covered with small and thin 
scales, which extend at least to posterior portion of interorbital region, but it is diffi- 
cult to see how far. Dorsal V, 35. Anal 32. Pectoral rounded nearly as long as 
head reaching beyond origin of anal. Ventral very little shorter, about s /6 of length
