Arte didraco skottsbergi is a true antarctic representative of this genus, this is 
evident as well judging from the localities where it has been caught, as from the 
prevailing physical conditions where it lives, in a water with a temperature below 
zero ! 
7. Pleuragramma antarcticum BOULENGER. 
i specimen from the ventricle of Leptonychotes weddelli, of Jason Land I 2 9 / I 1902. 
The tail of this specimen is broken off, but otherwise it is in a rather good 
condition and it can therefore be concluded that the figure, which BOULENGER has 
communicated in the “Report on the Collections of Natural History made in the 
Antarctic Regions during the Voyage of the Southern Cross” 1 PI. XVIII, and which 
he regarded “as, to some extent, a restoration”, is correct. 
The find of Pleuragramma in the Graham Region is from a zoogeographical 
point of view very important, as it indicates that this, most antarctic of all fishes 
hitherto known, has a circumpolar distribution as it has been found at two almost 
opposite sides of the Antarctic Region. 
Fishing at Paulet Island . 3 
During the winter 1903 it was a very useful as well as appreciated sport to 
fish with hook and handline through holes made in the ice. It was certainly rather 
hard work to make a satisfactory hole through the ice, which was about i r /a m. 
thick, but when such a one was made, a rich reward sometimes remunerated the pa- 
tient and diligent fisherman. With good luck the day’s catch could amount to about 
100 small fishes. All in all about 14,000 fishes were caught in this way by the, on 
Paulet Island, wintering party. They were, however, all of them small. The fishing
