between the sexes. I regret that the time at my disposal has been too short to allow 

 of the complete examination of these series of specimens. 



By far the greater part of the collection was made at the South Orkney Islands, 

 mainly at Scotia Bay, Station 325, lat. 60 43' S., long. 44 38' W., the winter quarters 

 of the Scotia. This appears to be a good collecting-ground for Amphipoda, particu- 

 larly, of course, for the Lysianassidse, and the forms obtained from this locality are 

 extremely useful for comparison on the one hand with those obtained in 1882-83 by the 

 German Transit of Venus Expedition from South Georgia, and on the other hand with 

 the specimens collected by the French Antarctic Expedition from Port Charcot, Wandel 

 Island, and other neighbouring localities. A few specimens were obtained from stations 

 further south, at localities intermediate between Kerguelen Island and those already 

 mentioned. Besides these, a small number of species was gathered at Gough Island, a 

 locality from which very few Amphipoda had hitherto been described ; others at the 

 Falkland Islands ; and some were obtained at Cape Town and Saldanha Bay in South 

 Africa, and help to show the relation of the Amphipoda of South Africa to those of the 

 various sub-Antarctic lands. 



A few species were collected in the northern and tropical parts of the Atlantic on 

 the voyage out and on the homeward voyage. As the greater part of the collection 

 is from Antarctic and sub-Antarctic regions, I have kept these Atlantic species in a 

 list by themselves, distinct from those gathered in the sub-Antarctic localities, under 

 which I include Gough Island and South Africa. 



As I was able to consult the reports on the Amphipoda of some of the Antarctic 

 Expeditions, and already had some acquaintance with several of the sub-Antarctic 

 species, it seemed a favourable opportunity for endeavouring to compare the results 

 as far as possible, and to determine cases where the same species had been described 

 under different names by different authors. In this effort I have been greatly assisted 

 by the kindness of many friends. Dr G. PFEFFER and Dr 0. STEINHAUS of the 

 Hamburg Museum very kindly placed at my disposal everything that I needed 

 from the collections made at South Georgia by the German Expedition in 1882-83, and 

 described by Dr PFEFFER in 1888 ; Monsieur EDOUARD CHEVREUX has sent me co-types 

 of several of his species ; from Mr A. 0. WALKER and from the British Museum I have 

 had co-types of many of the species obtained by the Southern Cross and Discovery 

 Expeditions, and described by Mr WALKER ; while the Eev. T. R. R. STEBBING and the 

 authorities of the Vienna Museum have supplied still other specimens that have been 

 extremely useful for comparison. Later on, when most of the work was completed, I 

 was able, through the kindness of Dr W. T. CALMAN, to check my results by comparison 

 with types and other specimens in the British Museum. At the same time, I have been 

 able to see the Amphipoda collected by Sir E. SHAUKLETON'S British Antarctic Expedi- 

 tion in 1908-09, which had been placed in Mr HODGSON'S hands ; and in several cases I 

 have been able to compare the Scotia specimens with New Zealand specimens that I 

 had brought with me to England. To all those who have assisted me in these various 

 ways I desire here to record my most grateful thanks.
