From these measurements is conspicuous tliat the snout, as usual, is smaller in 

 younger individuals than in older, but also that, contrary to the rule, the eyes 

 are comparatively smaller and the interorbital space broader in young than in old 

 specimens. 



Nototlicnia inizops var. iiudifrotis appears to be very common at the coast of 

 South Georgia in a depth from 10 to 250 m. But it was also found further south 

 within the truly antarctic region as is recorded in another chapter. X. iiiizops was 

 originally described from Kerguelen Land. The distribution of the species is tlius 

 by the discoveries of the Swedish Antarctic Expedition proved to extend over at 

 least half the subantarctic region over the Atlantic and Indian quadrants. 



The colour of one specimen of this fish is shown on PI. I fig. 2 where a sketch 

 made by Mr. Skottsberg from a living specimen is reproduced. Concerning the 

 colours of the specimens caught at stat. 20 the label informs us: "the largest brownish 

 red on the sides, the others with dark spots on a whitish ground-colour, belly white". 



6. Notothenia larseni - n. sp. 



(PI. 1 fig. 3.) 



I specimen from stat. 17, Shag Rocks, \V. of South Georgia, depth 160 m., 

 gravel and sand, temperature at bottom + 2,05° C. 19th of April 1902. 



5 specimens from stat. 34, outside Cumberland Bay, South Georgia, depth 252 —

 June 1902. 



D. VI, 37-39. A. 38. P. 26. Sq. 69-76. 



Depth of body 4'/3 to 5 times in total length without caudal. Length of head 

 y!i times in total length. Head and body rather compressed. Head rather pointed 

 with eyes protruding. Upper contour from snout to first dorsal almost a straight 

 line. Diameter of eye 3 times in length of head. Interorbital width 11 to 13 times 



' The supraocular skin is not contained in this mrasurement. 



" Named after Captain C. A. Larsen renowned from his voyages in the Antarctic regions, and chief 

 n.avigator of the Swedish Antarctic expedition.
