Some forty species of fish were taken, and it was reckoned that the most important were : 



Squalus lebruni 

 Psafnmobatis spp. 

 Rajidae (several spp.) 

 Clupea fuegensis 



Macrurotius magellanicus 

 Merluccius hiibhsi 

 Salilota australis 

 Cottoperca gobio 



Notothenia ramsayi 

 N. gunt fieri 

 Champsocephalus esox 

 Stromateus maculatus^ 



The existence of overlapping characters in the ' tesselata group ' of Notothenia was noted in the 

 field, also the profuse variation among the Rajidae of the locality, which necessitated a large collection

for further revision. Five teleosts new to science were collected, and specimens of Cottoperca gobio 

 and Dissostichus eleginoides much larger than any previously recorded were obtained. 



The most important result of the survey was to demonstrate that hake {Merluccius hiibbsi) were to 

 be found in moderate quantity on the shelf to the north and west of the Falkland Islands. This fish
