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 Lysianasside, 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, | 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, 1t 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. Prerrer and Dr O. Sreruaus 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 PFErrer in 1888; Monsieur Epovuarp CHEVREUX has sent me co-types 
of several of his species ; from Mr A. O. Watker 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 Waker; while the Rev. T. R. R. Srepprne 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. Caiman, 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 HE. SHackieton’s British Antarctic Expedi- 
tion in 1908-09, which had been placed in Mr Hopeson’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.
