THE FISHES OF THE SWEDISH SOUTH POLAR EXPEDITION. 
I I 
to make this identification because I have only one specimen which is quite young. 
The name M. holotrachys was also given and the diagnose based on a single speci- 
men so that the possible variation of the species has not been ascertained. The 
specimen described by GÜNTHER was found “East of the mouth of Rio de la Plata” 
in a depth of 600 fathoms by the Challenger Expedition. 
12. Myxine australis JENYNS. 
Several specimens from Ushuaia, depth 30 m., shells and gravel. 20th of March 
1902. 
The conditions of this locality proves that M. australis is less exclusively con- 
fined to muddy bottom. 
At, and in the mouth of, a fresh water rivulet emptying into Tekenika Bay, Tierra 
del Fuego, partly in brackish, but partly also in fresh water, a kind of large fishes 
were caught in a fair number by seining. The water was so shallow that the mem- 
bers of the fishing party could manage the small seine wading in the water with 
top boots. From 10 to 80 fishes could be caught at one time and as they were 
rather large, 60 to 70 cm. in average, this kind of fishing caused a great excitement 
among the crew. It was certainly also a lively scene to see the great fishes and 
the sailors splashing in the shallow water. The people residing at Tekenika Bay, 
and two falklanders hired as sailors termed these fishes “mullet”, but they were 
certainly no members of the genus Mugil as they had a long dorsal fin. Their 
colour was light greyish above shading into whitish or silvery below. Mr. ANDERS- 
SON thought that they resembled, to some extent, a Merluccius , but the specimens 
preserved were lost, among so many other valuable collections, with the sinking vessel. 
It is not easy to express any opinion about them now, but just because the zoo- 
logist of the expedition was sure about their identification when the preserved ma- 
terial had been carried home, as he certainly hoped it should be, he made no further 
examination of, or notes about them as his time was much occupied with such a 
great number of other things. 
A similar fishing was also done at Port Albemarle, Falkland Islands, although 
not quite so successfully.
