Introduction. 



During her famous circumnavigation of the world, H.M.S. Challenger left the 

 Cape of Good Hope on the 17th December 1873, and, proceeding in a south-easterly 

 direction, visited in succession Prince Edward and Marion Islands, the Crozet Islands, 

 Kerguelen Island, and Heard Island. From Heard Island the Expedition sailed south- 

 ward, and on the 16th February 1874 passed ten miles beyond the Antarctic Circle in 

 longitude 78° 22' E., the ship being at this time surrounded by a large number of huge 

 tabular icebergs, some of them four miles in length, and all with perpendicular sides 

 rising about 200 feet above the sea-level. From this most southerly point the Challenger 

 took a north-easterly course towards Melbourne in Australia, where she arrived on the 

 17th March 1874. 



Throughout this cruise to the Antarctic Eegions the Expedition made a very large 

 number of observations on the meteorological, physical, chemical, and biological conditions 

 of the Great Southern Ocean. In this communication it is proposed to deal chiefly 

 with the biological results, and more especially with the biological results obtained in 

 the deep water and shallow water trawlings and dredgings of this region of the
