With BOULENGER ' I feel convinced that Fischer's Notothenia angustifrons " 

 ought to be referred to GüNTHER's N. viarioneiisis ' in such a \va)' 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." s 

 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 Nototlienia 

 mario7iensis aiigiistifrons. 



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. 



(I'l. Ill h^. 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' 2 to 33/5 times in total length. Diameter of eye about 4 times in length 

 of head. Interorbital width about 6'/2 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 5, 6 of length
