4 DISCOVERY REPORTS 



will include the important collections made during the trawling survey of the Magellan- 

 Falkland Islands region, and will also deal with the fishes of the coast of Chile. The 

 fishes of South Georgia, the South Orkneys, the South Shetlands, and those of the 

 Antarctic Continent, will form the subject of the last section of the report. 



On her first commission the ' Discovery ' made brief calls at Ascension and Tristan 

 da Cunha on her way to the south, and a few fishes were obtained at both these islands. 

 In July 1927 she called at the Cape, and while the ship was in dock at Simon's Town 

 Mr E. R. Gunther and Mr F. C. Fraser were able to make a trip lasting about five days 

 in one of the South African commercial trawlers (S.T. 'Richard Bennet') and to 

 preserve a valuable collection of deep-water fishes obtained with the trawl. On the 

 homeward voyage in 1927 the 'Discovery' made several hauls off the coasts of Angola 

 and French Congo, and off Annobon, obtaining a very interesting series of fishes, 

 several of which have proved to be new to science. After leaving the Gulf of Guinea a 

 call was made at the Cape Verde Islands, where a few fish were collected. In June 

 1927 the 'William Scoresby ' was at Gough Island, and one or two fishes were obtained 

 from here. 



All the text-figures accompanying this report are the work of Lieut.-Col. W. P. C. 

 Tenison, D.S.O., who has prepared the drawings with his customary care and skill. 



The author takes this opportunity of expressing his sincere thanks to the members 

 of the Discovery Committee for permission to study these collections and to undertake 

 the preparation of this report.
