AMPHIPODA OF THE SCOTTISH NATIONAL ANTARCTIC EXPEDITION. 457 
It is a pleasure also to mention here my indebtedness to those who have assisted in 
other ways. I wish particularly to thank Dr E. J. Auuen of the Marine Laboratory, 
Plymouth, for allowing me to make such free use of the facilities offered by the institu- 
tion under his charge ; without his assistance it would have been impossible to do the 
work in the time. Dr W. T. Catan of the British Museum, besides sending me co- 
types of species I required, has assisted me in the examination of others at the Museum 
itself and by his advice on many difficult points. Professor WoLrTERECK of Leipzig 
and Dr A. Bexnine of the Zoological Station at Saratov have most obligingly communi- 
cated to me some of the results of their examination of the Amphipoda of the German 
South Polar and other Expeditions, which are as yet unpublished, though in the printer's 
hands. To Mrs KE. W. Sexton I am indebted for the loan of many papers and books 
that I required, for the keen interest which she has shown in the work during its 
progress, and for the great care and skill with which she has prepared the drawings of 
most of the figures for this paper. 
In order to make clear the various references that will be given below, it may be 
well to state very briefly the growth of our knowledge of the Antarctic and sub-Antarctic 
Amphipoda. That knowledge dates back to the years 1839-40, when three expeditions— 
the British, French, and American—visited Antarctic seas. The British leader, Sir JamEs 
CLARKE Ross, penetrated very far south in his memorable voyage, and during the 
expedition several Crustacea were collected, including some Amphipoda. No special 
report on these Amphipoda was published, but they appear to have been deposited in 
the British Museum, and several of them were afterwards described by Spence BatE 
and other writers. The Crustacea collected by the American Expedition were described 
by J. D. Dana in his well-known work, which forms one of the fundamental treatises 
for the study of the Crustacea. In it many Amphipoda are included. For many years 
after 1840 no further advance was made, and there is nothing noteworthy to be recorded 
until 1874, when several expeditions were sent out to southern seas for the observation 
of the Transit of Venus, and during these expeditions various collections were made. 
The Amphipoda of the British Expedition from Kerguelen Island were described by 
K. J. Migrs, and others collected by the American Expedition by 8S. I. Surru. The 
French Expedition spent some time at the Campbell Island, and the Crustacea 
collected were afterwards described by Henri Frnaor in the Mission de I Ile Campbell, 
in which he also included a general list of the Crustacea of New Zealand. This 
report was not published till the year 1885, and in the meantime a beginning had 
been made with the study of the Crustacea of Australia and New Zealand by Professor 
W. A. Haswett and Mr G. M. Tuomson respectively. During the years 1873 to 
1876 the Challenger Expedition had made numerous collections in sub-Antarctic 
and a few in Antarctic seas, and these were most fully described and figured by the 
Rey. T. R. R. Sressine in his elaborate report published in 1888. In the same year, 
but at a slightly earlier date, there was published a report by Dr G. Prerrer on the 
Amphipoda collected at South Georgia by the German Transit of Venus Expedition of
